Full textThe aims of the Thesis were: to investigate and quantify the factors influencing the production of maximum isometric grip strength force in a sample of Australian teenagers when using JamarTM-like handgrip dynamometers; to determine the reliability of this measure over long and short retest intervals; to establish a database of anthropometric and strength values for this group and prediction equations for premorbid strengths to aid assessment of recovery in those with upper limb pathologies. The history of these handgrip dynamometers demonstrates that they have been employed in one form or another for over three hundred years and are still widely used today in hand rehabilitation and medical examinations. Many new types of dynamometers have been constructed subsequent to the ubiquitous JamarTM and have all been briefly reviewed here. Handedness (dominance) was thought to be a possible factor influencing grip strength performance and was later evaluated. But first, the Edinburgh Handedness Inventory was tested with 658 teenagers and 64 adults and confirmed to be a valid tool for assessing handedness. Its validity was improved by substituting the tasks of sweeping and opening the lid of a box for hammering and use of a screwdriver. Its excellent reliability (ICC = .78, p < 0.01) was confirmed with 45 teenagers and 45 adults. There were 235 teenagers who performed maximal isometric grip strength tests and from the results a local database was created. It was confirmed that the grip strength difference in males and females becomes significant after the age of 13 years, and that the average teenaged male is stronger than the average teenaged female by 11.2 Kg force (p < .01). Height, weight, BMI, hand dimensions, past upper limb injuries, degrees of handedness and exercise levels were measured and compared with known norms to establish that the grip strength tested sample of teenagers was representative of urban teenagers in Australia. The influence of handedness on maximal grip strength in dominant and non-dominant hands was unable to be completely ascertained due to the vast majority of the sample of teenagers being right-handed. Only 13 of the 235 teenagers used their left hand for most tasks, with another 20 using their left hands for a small majority of tasks. There was a grip strength bias towards the dominant hand of 2.63 kg force (p < .01). The most accurate way to predict the grip strength of one hand is by knowing the grip strength of the other hand. Prediction models found that 90% (R2 adj .902) and 70% (R2adj .702) of the variance in one hand could be accounted for by the grip strength of their other hand for male and female teenagers, respectively. Prediction equations were also created to assist in estimating the pre-morbid grip strength of teenagers suffering from bilateral hand injuries. If for the males, measurements for height and hand surface area were entered into these models, the grip strength of the dominant and non-dominant hands could be estimated with 62.6 and 63.5% of the variance between the real and predicted scores accounted for, respectively. For the females the prediction models using height and hand surface area could only account for 33.9 and 42.8% of the variances, with no other independent variables improving the prediction equations. The reliability of the maximal grip strength performance of 154 of these teenagers was retested after one or four weeks. A number of sub-group permutations were created for age, gender, retest time interval and handedness groups. The measures of grip strength for males were highly reliable with ICC (3,1) values ranging from .91 to .97. These measures were significantly higher than that obtained from the females, where reliability values ranged from .69 to .83. Handedness played a significant part in grip strength reliability. The dominant hand of right-handed teenagers achieved an ICC (3,1) of .97, as contrasted with the non-dominant hand of left-handers who attained a very poor ICC (3,1) of .27. The shape of the hands of the males did not influence their grip strength or their reliability values, which ranged from .954 to .973. The shape of female hands did not affect their ability to generate maximal grip strength, only its reliability. The females with hands shaped squarer-than-average had mean grip strength reliability values of ICC (3,1) at only .48, in contrast to those with longer-than-average hands who achieved a mean ICC (3,1) of .92. The handle shape of the dynamometer may disadvantage square-handed females, and this should be further investigated.

Full textGrip strength is a valuable indicator that can be used to describe not only hand function, but also the overall functional status of the upper-limb strength or even of the entire body. A number of improvements could be made. The aim of this thesis is to contribute to the development of new methods of measurement and analysis of grip-strength. After an in-depth literature review of the most relevant aspects of grip-strength testing, an intelligent dynamometer for home-based testing, the Grip-Ball, is presented. This dynamometer consists of a pressure sensor and a wireless communication system, which are inserted in-side a supple, air-tight ball, in order to measure the pressure inside the ball when it is squeezed. In addition to the Grip-Ball, another innovative dynamometer, the Myogrip, which is well-suited to the measurement of very weak grip strength, was compared to two of the most widely-used dynamometers (Jamar and Martin Vigorimeter). Furthermore the investigation was performed to evaluate the effects of elbow position and of the handle sizes when using these three dynamometers. The development of simple predictive model for the maximal grip strength based solely on hand circumference is presented in a third study, with this simple model suitable for routine use. The last three chapters are devoted to the presentation of advanced methods of signal processing obtained from sustained grip-strength contractions: Hilbert-Huang transform, fractal analysis, and recurrence analysis. These methods are able to characterise the effects of fatigue, tremor, disease or age during these sustained contractions

Full textIntroduction: A complex interaction between muscles, tendons, bones, joints and nerves are required for optimal function of the human hand. It is known that an individual’s grip strength is vital for performance of physical demanding tasks such as strength training with free weights. Strength training including a thicker grip around the bar may enhance the strength of the grip in the athlete without other special routines for grip strength development. The purpose of this investigation was to examine the difference in performance in multiple repetitions in two strength training exercises using two different sizes on the bar, to look for correlations between grip strength of the subjects hand and the amount of repetitions executed with two different size of the bar and finally the correlation of hand size and the amount of repetitions executed with two different size of the bar.
Method: 15 strength training men (23,9 ± 4,1 years), underwent measurements of hand size, maximum grip strength, 1 repetition maximum (1RM), a 80 % of 1RM weight strength test with two different bar sizes.
Results: The results from the present investigation indicates a 21,1 % reduction of 80 % of 1 RM weight performance in repetitions executed in the bench press with the thicker diameter of the bar and a 66,2 % reduction in repetitions executed with a 80 % of 1 RM weight in the lying bench row with the thicker diameter of the bar. The size of the hand or the maximum grip strength does not influences the performance in the 80 % of 1 RM strength test.
Conclusion: With support of the results from this present investigation the size of the bar diameter significant influences the performance in maximum repetitions executed in a set in strength training with free weights, in a rowing exercise the repetitions executed reduced with 66,2 % and in the bench press the reduction of executed repetitions were 21,1 % with the thicker diameter of the bar. The size of the hand do not influences the performance of maximal executed repetitions with the thicker bar diameter. Maximal grip strength has no influence of the performance according to the findings of this investigation.

Full textBackground: Core stability is necessary to keep balance and enables force to be transmitted through the body. This makes core stability important in everyday chores, sport performance and to reduce risk of injuries. A better understanding of the core stability in different sports can develop athletes training programs, not only to improve the core stability itself, but also to improve overall performance. Aim: The aim of this study was to examine the differences in core endurance between young female horseback riders and soccer players, and the core endurance association with hand grip strength and spinal rotation mobility. Methods: The McGill’s core endurance test was used to examine the core endurance between female horseback riders (n = 10) and soccer players (n = 10), age 16-20. The hand grip strength was examined with a hand grip dynamometer and was used to get an indication of overall body strength. The spinal rotation mobility was examined with a Myrin goniometer. Shapiro-Wilks was used to confirm the normality of the data. Independent sample t-test was used to compare core endurance time (sec.) between the horseback riders and the soccer players. The significant level was set at < 0.05. A strength ratio was calculated (kg/kg body weight), and the Pearson’s correlation coefficient was used for examining the association to core endurance (sec.). Pearson’s correlation coefficient was also used to examine the association between the spinal rotation mobility (°) and core endurance (sec.). High correlations were set at r > (0.7), moderate when r = (0.3- 0.7) and low when r < (0.3). Results: The result showed that horseback riders had better endurance in the trunk extensor test than the soccer players (p = 0.006). Hand grip strength showed moderate correlation with the endurance time of the trunk extensor test (r = 0.631, r² = 0.398), and with the lateral flexor tests (r = 0.411, r² = 0.169; r = 0.615, r² = 0.378). Low correlation was shown with the trunk flexor test (r = 0.197, r² = 0.039). The spinal rotation mobility test showed low correlation with all the core endurance tests (r >0.3). Conclusion: The results indicates few differences between the horseback riders and the soccer players, which is not enough to draw a conclusion. The correlation between hand grip strength and the core endurance tests indicates that a better core stability might be associated to an increased overall body strength.

Full textBackground: Sportsfysiotherapists help athletes improve their sport-specific abilities. In ice-hockey, the slap shot is the shot-technique that produces the greatest puck velocity. Hand grip strength have shown to be important to hockey players sport-specific abilities and stick movements. Skating speed is an important variable for the hockey players overall performance. Aim: To investigate the mean hand grip strength, skating speed and shooting speed on a group swedish male elite ice-hockey players and investigate the correlation between these factors. Methods: A team of twentythree male elite hockey players were asked to participate in the study. Twenty players participated. A cross-sectional study with a quantitative approach consisting of single measures on one group. Puck velocity, handgrip strength and skating speed were measured one time per player on three separate sessions. Results: Seventeen hockey players completed the studie. The mean puck velocity was 128,167 km/h. The mean hand grip strength were 60,2 kg. The mean shooting speed were 1,405s measured on a distance of 15 meters. The correlation between puck velocity and hand grip strength were not statistically significant weak negative (r=-0,042; p=0,876). The correlation between mean puck velocity and shooting speed were not statistically significant weak negative(r=-0,177; p=0,508). Conclusion: The mean maximal values of puck velocity, hand grip strength and shooting speed are comparable with similar values from other studies. The correlation between puck velocity and hand grip strength and shooting speed were weak which indicate that these factors do not affect the puck velocity from a slap shot. Further studies are needed to strengthen this study's result.

Full textINTRODUCTION: The effects of aging on the respiratory system begin at approximately 25 years of age and lead to a decrease in the maximum function of this system. This diminished function is noticeable on lung volumes and capacities, on respiratory muscle strength and airflow, predisposing the elderly to complications that may result in hospitalization and even death. The mass and reduced muscle strength is already well studied in this population, but with few studies investigating the relation with the respiratory function. OBJECTIVE: To evaluate the relationship between respiratory muscle strength and palmar grip strength in institutionalized and community aged individuals. METHOD: It is characterized by a cross-sectional study with 64 volunteers, being institutionalized 33 (GI) and 31 from the community (GC). The maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), peak expiratory flow (PF), dominant palmar grip strength (FPP D) and non-dominant (FPP ND), anthropometric data and level of physical activity (short IPAQ). The data were submitted to statistical analysis through t Student test for independent samples for comparison between groups, covariance analysis (ANCOVA) controlled by covariate age for respiratory variables and for palmar grip strength, Pearson test for correlation evaluation of the variables and the linear regression analysis to identify the influence of the respiratory variables on the FPP, besides the Bonferroni correction to exclude the type I error. RESULTS: The values found in the respiratory and strength tests between the groups, differed statistically even by the covariable age, and the GI presented values lower than the GC. In GI, we found no correlation between respiratory and FPP variables, but the respiratory predictor most strongly associated with FPP D was the PEmax (p = 0.04). In the CG, correlation was found between PImax and FPP D (r = 0.539), PEmax and FPP D / ND (r = 0.62 / 0.6), PF and FPP D / ND (r = 0.64 / 0, 43) and the respiratory predictor most strongly associated with FPP D was PF (p = 0.009) and PEmax (p = 0.028) and for FPP ND was PEmax (p = 0.021). In the joint analysis of the groups, an association between PImax and FPP D / ND (r = 0.40 / 0,41), PEmax and FPP D / ND (r = 0.57 / 0.54), FP and FPP D (P = 0.01) and PEmax (p = 0.03) and for FPP ND it was the PEmax (p = 0.07) and ND (r = 0.57 / 0.47) and the respiratory predictor most strongly associated with FPP D = 0.008) and PF (p = 0.041). CONCLUSION: GI shows greater respiratory muscle weakness and these variables do not correlate well with PPF. In the elderly in the community, PF and PEmax appear to be a good predictor of PPF

The purpose of this study was to evaluate the parameters of the isometric handgrip strength curves in highly trained judo athletes from different categories. 44 judo athletes who were participating of the VII Troféu Brasil, which took place in Porto Alegre, RS and 25 Physical Education students participated of this study. The handgrip strength was evaluated using a dynamometer built at LABIN, located on CEFID/UDESC. The evaluation of the judo athletes was performed during the championship weighing, in Porto Alegre, and the evaluation of the students was performed at LABIN. The handgrip strength was evaluated for 10 seconds, with one attempt on the dominant hand and one attempt on the non dominant hand, on the seated position adapted from the ASHT. The parameters evaluated were Maximum force (FMAX), Time to maximum force (T100), impulse to maximum force (imp100), rate of decrease (IQ) and impulse (imparea1). For the analysis regarding the athletes, the individuals were divided into three groups, according to their body mass (MC), into two groups according to their results and into two groups according to T100. To eliminate the influence of MC over the strength values recorded on both tests and allow the comparison between individuals of different categories and consequently of different body sizes, the allometric scaling was performed on the FMAX. After the statistical analysis was conducted, differences between the lighter and heavier categories in the handgrip strength curve parameters were found. In this case, the correction of the strength values by the corrected MC eliminated the influence of the MC for the categories. Concerning the result of the competition, relative values highlighted the differences between the groups. It is suggested that further studies are conducted, investigating the handgrip strength in judo athletes, for a better understanding of the differences between he categories and a closer investigation to the sport.
O objetivo deste trabalho foi avaliar os parâmetros das curvas de força de preensão manual isométrica em judocas de alto nível competitivo e de diferentes categorias. Participaram do estudo 44 judocas participantes do VII Troféu Brasil, realizado em Porto Alegre, RS. Para a mensuração da preensão manual foi utilizado um dinamômetro de preensão manual desenvolvido no Laboratório de Instrumentação (LABIN), do Centro de Ciências da Saúde e do esporte (CEFID) da Universidade do Estado de Santa Catarina (UDESC). A avaliação dos judocas foi realizada durante a pesagem da competição, em Porto Alegre, e a dos estudantes foi realizada no LABIN. A preensão manual foi avaliada durante 10 segundos, uma vez na mão dominante e uma vez na mão não-dominante, na posição sentada, adaptada da Sociedade Americana de Terapeutas da Mão (ASHT). Foram analisadas a Força máxima (FMAX), o Tempo até a força máxima (T100), impulso até a força máxima (imp100); Índice de queda (IQ) e o impulso total (imparea1). Para as análises, os judocas foram divididos em três grupos de acordo com a massa corporal (MC), em dois grupos de acordo com o resultado na competição e para a análise em função do T100 em dois grupos. No intuito de eliminar a influência da MC sobre os valores de força registrados em ambos os testes e possibilitar a comparação entre indivíduos de diferentes categorias e conseqüentemente de diferentes tamanhos corporais, foi realizado o ajuste alométrico na FMAX pela MC1, MC0,67 e MC0,393. Depois de realizada a análise estatística, foram encontradas diferenças entre as categorias mais leves e as mais pesadas de judocas em parâmetros da curva de preensão tanto sem quanto com ajuste alométrico. O ajuste alométrico da força pela MC0,393 pareceu eliminar a influência da MC na força para judocas de diferentes categorias. Considerando o resultado da competição o MC0,393 evidenciou a diferença de força entre os grupos em valores ajustados, sendo os melhores colocados mais fortes tanto absoluta quanto relativamente. Sugere-se que mais estudos sejam realizados investigando a força de preensão manual em judocas, buscando um maior entendimento das diferenças apontadas entre as diferentes categorias e uma maior aproximação da prática do esporte.

Work-related repetitive strain injury (RSI), one of the work-related musculoskeletal disorders, is the most commonly reported occupational illness, yet the pathophysiological mechanisms are not yet clear. Using our unique RSI animal model, pathophysiological tissue responses can be examined simultaneously with behavioral responses that serve as indicators of sensorimotor function. Studies in humans and with this animal model have shown that prolonged performance of repetitive tasks leads to declines in grip strength and increased of serum pro-inflammatory cytokines, both valuable biomarkers of underlying tissue injuries. Identification of biomarkers would help to elucidate the time course of the inflammatory stage of these disorders and disease progression. Sickness responses/behaviors, normal responses and behaviors occurring as a consequence of infection or illness, are responsible for re-organizing perceptions and actions to enable individuals to respond appropriately to the infection, injury and other illnesses. These behaviors can include malaise, fatigue, increased irritability and social withdrawal, behaviors that can be beneficial when ill for avoiding others and enhancing wellness. However, sickness behaviors can also include depression, sleep disorders and an enhanced perception of illness. Although recent studies have shown that circulating pro-inflammatory cytokines in serum may trigger sickness behaviors, only a few studies have examined if there is an association between work-related musculoskeletal disorders and subsets of sickness behavior; no one to date has elucidated any plausible biological cause of this association. Also, the combined effects of both aging and performance of repetitive tasks needs more evaluation since several epidemiological studies have shown a relationship between advancing age and susceptibility to musculoskeletal disorders. Therefore, using female Sprague-Dawley rats, the aims of this dissertation project are to: 1) To determine if a systemic inflammatory response is maintained long-term in rats exposed to a moderate demand lever-pulling task with high repetition, low force (HRLF) requirements; if aging enhances this systemic inflammatory response and if this response correlates with functional motor declines; 2) To determine if performance of repetitive upper extremity tasks leads to the development of sickness behaviors (weight loss, decreased social interaction and increased aggression); 3) To determine if a relationship between repetitive upper extremity tasks lead to the development of dose- and age-dependent sickness behaviors, and, to determine if increased serum or brain inflammatory cytokines are plausible mechanisms for the induction of sickness behaviors in this model; and, lastly, 4) To determine if prophylactic or secondary systemic treatments with anti-inflammatory drugs (anti--tumor necrosis factor alpha or ibuprofen) reduces sickness behaviors in rats performing a high demand high repetition high force (HRHF) reaching and handle pulling task. This finding would be in further support of an underlying task-induced inflammatory mechanism contributing to these sickness behaviors. In the first study, the relationship between serum and grip strength was examined in aged and young adult rats performing a HRLF task. Serum levels of interleukin 1-alpha (IL-1α), interferon-gamma (IFNγ) and IL-6 were higher in aged rats in general, compared to young adult rats. Each increased more in aged trained-only and 12-week HRLF rats than in young adult trained-only and 12-week HRLF rats. Serum IL-6 showed the greatest increases, with the highest levels observed in aged 12-week HRLF rats. Grip strength declined with task performance in both age groups; however, this decline correlated negatively and only moderately with serum IL-6 levels in aged rats. Thus, aging enhanced a serum cytokine response in general, a response that was even greater with repetitive task performance. Grip strength was adversely affected by task performance in both age groups, but was apparently influenced by factors other than serum cytokine levels in young rats. In the second study, the relationship between sickness behaviors (weight loss, duration of social interaction and aggression towards novel juvenile rats), serum cytokines and brain cytokines were examined in aged and young adult rats that trained to one of two task levels before performing a HRLF task. Decreased duration of social interaction and increased aggression was greater in both young adult and aged rats that trained for 10 min/day for 4-5 weeks to learn a high force (TRHF) task, compared to young adult and aged rats that learned a low force (TRLF) task. TRHF and TRLF rats of both age groups then performed a HRLF task for 6 to 24 weeks, rats termed TRHF-HRLF and TRLF-HRLF, respectively. Declines in social interaction resolved by week 3 in young adult TRHF-HRLF rats, but were still evident in 6-week aged TRHF-HRLF rats (the final endpoint for TRHF-HRLF rats). Significant increases in aggression were observed only in TRHF-HRLF rats, in both age groups. Declines in social interaction were also observed in aged rats performing a TRLF-HRLF task through week 9, but not in young adult TRLF-HRLF rats, even those performing the HRLF task for 24 weeks. These behaviors correlated moderately with increased serum IL-6 observed in the aged task rats (both TRHF-HRLF and TRLF-HRLF) and young adult TRHF-HRLF rats, although serum TNFalpha and IL-1beta also increased with task performance. Increased IL-6 and IL-6 receptor was detected immunohistochemically in brains of aged TRHF-HRLF rats, specifically in ependymal and endothelial cells, as well as glial cells and neurons of the anterior cingulate cortex and paraventricular nucleus. Thus, training to high force, even for a short time period, induced increased sickness behaviors. Aging contributed to increased sickness behaviors in repetitive task rats, and to increased expression of IL6 and IL-6 receptor in several brain regions. In the third study, the relationships between sickness behaviors (duration of social interaction and aggression towards novel juvenile rats), serum cytokines and brain cytokines were examined in young adult rats performing a high repetition high force (HRHF) task with or without anti-inflammatory medications. Rats that trained to high force (TRHF) had decreased duration of social interaction and increased aggression; these behaviors were prevented by prophylactic anti-TNFalpha or ibuprofen treatment. Untreated TRHF rats that went on to perform a HRHF task showed decreased social interaction and increased aggression through week 12; these behaviors were attenuated by secondary anti-TNFalpha and ibuprofen treatments. Untreated HRHF rats had increased serum GroKC, IFN-gamma, IL-1beta, MIP2, MIP3a and TNFalpha. These increases were attenuated after two weeks of anti-TNFalpha treatment in HRHF weeks 5-6, and after 8 weeks of ibuprofen (in HRHF weeks 5-12). The sickness behaviors correlated moderately with increased serum Gro-KC, MIP2 and TNFalpha, and were concomitant with increased IL-1beta immunoexpression in ependymal and endothelial cells in brains of untreated TRHF and HRHF rats. Both treatments reduced the increased brain IL-1beta expression. Thus, sickness behaviors induced by overuse are attenuated by anti-inflammatory interventions that reduce task-induced increases in systemic and brain inflammatory cytokines. In conclusion, both aging and task performance increased serum inflammatory cytokine responses, the latter in an exposure-dependent manner, with a greater serum cytokine response with performance of high force tasks than low force tasks. While grip strength was adversely affected by task performance in both young and aged rats, it was influenced by factors other than serum cytokine levels. In contrast, decreased duration of social interaction and increased incidence of aggression were influenced by task-induced increases in serum and brain inflammatory cytokines, responses attenuated to baseline levels with systemic anti-inflammatory treatments. Sickness behaviors were also dose- and age-dependent, with higher incidence with performance of high force tasks than with low force tasks, and higher incidence in aged rats. We postulate that the higher incidence in aged rats is due to aged-induced brain "inflamm-aging", as they also had increased immunoexpression of IL6 and IL6 receptor in blood brain barrier cells and in glial and neurons of the hypothalamic pituitary axis.

The objective of this study was to analyze the characteristics of grip in Judo. The study included 08 athletes with a degree of black belt in Judo, male, over 18 years, competing at the international level and who seek to place the 2012 London Olympics. To characterize the types of grip that make up the judo technique to grab the opponent, there were shots of fighting athletes in training, was used a spreadsheet where identifies the type of grip on the judogi specific locations and also in relation to specific by hand. As for the quantification of the kind of grip on fighting, videos of international competitions were analyzed, was used a spreadsheet that quantifies the number of grips on each site judogi the opponent, so that later was made an indirect relationship with the spreadsheet data characterization and thus to obtain a quantification of the types of grip in international fights. For the measurement of handgrip dynamometers were used developed by Instrumentation Laboratory (LABIN/CEFID/UDESC). The handgrip strength was measured for 30 seconds, three times in the dominant hand and three times in the non dominant hand with measures interspersed in his hands, sitting, adapted from the American Society of Hand Therapists (ASHT). Was analyzed the following parameters of the Force vs. Time curve of the grip types identified, maximum force (FMAX), reaction time (TREACT), time to maximum force (TFMAX), growth rate of force (TXCRESC) and the Index fall of force (IQ). Among the results cited that were identified in all three ways to grip used by judokas: Full Palmar, digit-palmar and a third consisting of an association between Digit-palmar and lateral pinch. To check the difference in the use of forms of grip, between the dominant and non dominant hand was used Wilcoxon test where differences were found in the use of all forms of grip, in his hands. To see if there was a difference between the parameters of force-time curve of the ways to grip seen between the dominant and non dominant hand was used T test for paired data in the parametric data and Wilcoxon test for non-parametric, difference lying only in the Index fall of force of the Full palmar. To correlate the use of a way to grip with the behavior of their parameters from force-time curve was used Pearson's correlation test for parametric data and Spearman correlation test for non-parametric, and correlation was found in four cases. Two correlations were positive: use of Digit-palmar grip and the maximum force Full Palmar in the dominant hand and Full Palmar grip use and time to the maximum force in the non dominant hand. The other two correlations are presented as negative: Full Palmar grip use and maximum force Palmar grip in the dominant hand and the use of the association of Digit-palmar and lateral pinch and reaction time of lateral pinch grip on non dominant hand. The data obtained from the study demonstrate the difference function and use of the hands of judo, and how the usage is correlated with the parameters of force-time curve, explaining a specific conditioning.
O objetivo deste trabalho foi analisar as características da preensão manual no Judô. Participaram do estudo 08 praticantes de judô com graduação de faixa preta, do sexo masculino, maiores de 18 anos, que competem em nível internacional e que buscam vaga para a Olimpíada de Londres 2012. Para a caracterização dos tipos de preensão que compõem a pegada do Judô, foram realizadas filmagens dos atletas desempenhando pegadas no treinamento, utilizou-se uma planilha onde se identifica o tipo de preensão em locais específicos do judogui e com especificidade também em relação à mão. Já para a quantificação do tipo de preensão em lutas, vídeos de competições internacionais foram analisados, utilizou-se uma planilha que quantifica o número de pegas em cada local do judogui do adversário, para que posteriormente fosse realizada uma relação indireta com os dados da planilha de caracterização e assim obtivesse-se uma quantificação dos tipos de preensão em lutas internacionais. Para a mensuração da preensão manual foram utilizados dinamômetros desenvolvidos pelo Laboratório de Instrumentação (LABIN/CEFID/UDESC). A Força de preensão manual foi avaliada durante 30 segundos, três vezes na mão dominante e três vezes na mão não dominante com mediadas intercaladas entre as mãos, na posição sentada, adaptada da Sociedade Americana de Terapeutas da Mão (ASHT). Foram analisados os seguintes parâmetros da curva de Força x Tempo dos tipos de pega identificados, Força máxima (FMAX), Tempo de reação (TREACT), o Tempo até a força máxima (TFMAX), Taxa de crescimento da força (TXCRESC) e o Índice de queda da força (IQ). Entre os resultados cita-se que foram identificadas no total três formas de pega utilizadas pelos judocas: Palmar Plena, Dígito-palmar e uma terceira que consiste em uma associação entre Dígito-palmar e Pinça Lateral. Para verificar a diferença no uso das formas de pega, entre a mão dominante e não dominante foi utilizado o Teste de Wilcoxon onde foi encontrada diferença no uso de todas as formas de pega, entre as mãos. Para verificar se existia diferença entre os parâmetros da curva força x tempo das formas de pega identificadas entre a mão dominante e não dominante foi utilizado Teste T para dados pareados nos dados paramétricos e Teste de Wilcoxon para os não paramétricos, encontrando diferença somente no Índice de queda da força de preensão Palmar Plena. Para correlacionar o uso de uma forma de pega e o comportamento de seus respectivos parâmetros da curva força x tempo foi utilizado o Teste de Correlação de Pearson para os dados paramétricos e o Teste de Correlação de Spearman para os não paramétricos, sendo que foi encontrada correlação em quatro casos. Duas correlações obtiveram resultado positivo: uso de preensão Dígito-palmar e a força máxima Palmar Plena na mão dominante e o uso da preensão Palmar Plena e o tempo até a força máxima na mão não dominante. As outras duas correlações se apresentaram como negativas: uso da preensão Palmar Plena e a força máxima de preensão Palmar na mão dominante e uso da associação Dígito-palmar e Pinça Lateral e o tempo de reação da preensão de Pinça Lateral na mão não dominante. Os dados obtidos com a pesquisa demonstram a diferença de função e de utilização das mãos dos judocas, bem como de que forma a utilização se correlaciona com parâmetros da curva de força x tempo, explicando um condicionamento específico.
