Pełny tekst źródłaAs lesões desportivas são um grande problema no que diz respeito à sua rápida reabilitação. Inúmeros estudos tentam encontrar a técnica mais rápida capaz de acelerar o processo da recuperação. A oxigenoterapia hiperbárica (OTH) é a aplicação de 100% de oxigénio numa câmara hiperbárica a pressões mais elevadas do que o nível do mar. A inalação de OTH comporta-se como um fármaco multifacetado dotado de efeitos anti-isquémicos, anti-hipóxicos, anti-edematosos, pós-lesão e anti-infecciosos. Portanto, o objetivo desta tese foi analisar a influência da OTH na recuperação de lesões desportivas, como contusão muscular e do ligamento cruzado anterior (LCA) pós ruptura. Em primeiro lugar, verificou-se se a aplicação de OTH melhorou as propriedades biomecânicas, tais como rigidez, alongamento máximo e peso máximo, dos gastrocnémios de ratos após induzir contusão muscular. Em segundo lugar, era de nosso interesse analisar, após de se ter induzido uma contusão muscular nos gastrocnémios dos ratos, a influência da OTH na bioenergética mitocondrial avaliada através do consumo de oxigénio e potencial transmembranar e susceptibilidade à indução do poro de transição de permeabilidade mitocondrial, em mitocôndrias isoladas. Finalmente, no último trabalho experimental, tentou-se verificar se a aplicação de OTH tem a capacidade de melhorar a neovascularização, por meio da análise do factor de crescimento do endotélio vascular (VEGF), bem como analisar a proliferação e a produção de proteína, em coelhos com ruptura do LCA. A OTH parece desempenhar um papel importante na recuperação de lesões musculares, mais especificamente, na contusão muscular em ratos, melhorando as propriedades biomecânicas musculares, tais como a rigidez e peso máximo e na bioenergética mitocondrial, onde o tempo até que o inchaço na mitocôndria iniciasse em grande escala foi menor no grupo submetido a OTH, assim como a amplitude de inchaço foi maior, o que atrasou a apoptose mitocondrial. Contudo, em relação à ruptura do LCA, a OTH promoveu a neovascularização, activando VEGF, mas no entanto, contribuindo para o aumento da espessura da cápsula. VII Palavras-chave: Oxigenoterapia hiperbárica, gastrocnémios, contusão muscular, propriedades biomecânicas, bioenergética mitocondrial, ligamento cruzado anterior, neovascularização, colagénio tipo I. Sports injuries is a major problem what concerns to its rapid rehabilitation. There is innumerous attempting to find the faster technique to apply to the injured ones to accelerate its recovery. Hyperbaric oxygen therapy (HBO) is the application of 100% oxygen in a hyperbaric chamber at pressures higher than sea level. The inhalation of HBO has already shown that behaves like a multifaceted drug endowed with anti-ischemic, anti-hypoxic, anti-edematous, pro-healing and anti-infective effects. Therefore, the objective of this thesis was to analyze the influence of HBO in the recovery from sports injuries such as muscle contusion and anterior cruciate ligament (ACL) rupture. Firstly, it was verified if HBO improved the biomechanical properties, such as hardness, maximum elongation and maximum weight, of rats’ gastrocnemius after inducing muscle contusion. Secondly, it was of our interest to analyze skeletal muscle mitochondrial energetic of rats’ gastrocnemius after induced muscle contusion, by determining end points related to oxygen consumption, transmembrane electric potential and permeability transition pore susceptibility in isolated mitochondria. At last, our last experimental work aimed to verify if HBO has the ability to improve neovascularization, through the analysis of vascular endothelial growth factor (VEGF) as well the proliferation and protein production, of rabbit ruptured ACL. HBO seems to play an important role in the recovery of muscle injuries, more specifically, muscle contusion in rats, by improving muscle biomechanical properties, such as hardness and maximum weight and in mitochondria energetic, where the time until large scale swelling initiates in mitochondria was lower in HBO and the swelling amplitude was higher, which delayed mitochondria apoptosis. However, concerning to ACL rupture, HBO increased neovascularization by activating VEGF, contributing for the increasing of capsule thickness. Les lésions sportives sont un grand problème en ce qui concerne la rapidité de sa réhabilitation. De nombreux études essayent de trouver la plus rapide et moins douloureuse technique capable d’accélérer le processus de récupération. L’oxygénothérapie hyperbare (OHB) consiste à l’inhalation de 100% d’oxygène dans un caisson étanche avec une pression plus élevée que celui de la mer. Il a été démontré que l’inhalation de l’OHB se comporte comme une drogue à multiple facette, qui permet d'agir sur l'ischémie tissulaire qu'elle qu'en soit la cause : vasculaire, traumatique, toxique, ou infectieuse. Pourtant, l’objectif de cette étude a été d’analyser l’influence de l’OHB dans la récupération des lésions sportifs, l’ecchymose du ligament croisé antérieur post rupture. Dans un premier temps, on a vérifié si l’utilisation de l’OHB améliore les propriétés biomécaniques, comme la rigidité, l’étirement maximum et le poids maximum, des Gastrocnémiens chez les rats après induire une ecchymose. Deuxièmement, cela été dans notre intérêts d’analyser, après induire une ecchymose des Gastrocnémiens chez les rats, l’influence du OBH dans la bioénergétique mitochondriale, évalué à travers la consommation d’oxygène, le potentiel transmembranaire et la susceptibilité d’induction du pore de transition de perméabilité mitochondrial, des mitochondries isolés. Pour finir, lors du dernier travail expérimental, nous avons essayé de vérifier si l’application de l’OHB a la capacité d’amélioré la néo vascularisation, en analysant le facteur de croissance de l’endothélium vasculaire (en anglais Vascular endothelial growth factor, VEGF), en analysant aussi la prolifération et la production de protéine, sur des lapins avec rupture du LCA. L’OHB semble avoir un rôle important dans la récupération des lésions musculaires, plus précisément sur l’ecchymose chez les rats, améliorant ainsi les propriétés biomécaniques musculaires, comme la rigidité, le poids maximum et la bioénergétique mitochondriale. Le temps pour que l’oedème dans la mitochondrie arrive à grande échelle a été plus faible dans le groupe soumis à l’OHB, comme l’amplitude de l’oedème fut plus grand, ce qui a retardé XI l’apoptose mitochondrial. Toutefois, en ce qui concerne la rupture du LCA, l’OHB a promu la néo vascularisation, activant le VEGF, contribuant à une capsule épaisse.

This thesis describes a compact, wireless, wearable system that measures, for purposes of biomechanical analysis, signals indicative of forces, torques and other descriptive and evaluative features that the human body undergoes during bursts of extreme physical activity (such as during athletic performance). Standard approaches leverage high speed camera systems, which need significant infrastructure and provide limited update rates and dynamic accuracy, to make these measurements. This project uses 6 degree-of-freedom inertial measurement units worn on various segments of an athlete's body to directly make these dynamic measurements. A combination of low and high G sensors enables sensitivity for slow and fast motion, and the addition of a compass helps in tracking joint angles. Data from the battery-powered nodes is acquired using a custom wireless protocol over an RF link. This data, along with rigorous calibration data, is processed on a PC, with an end product being precise angular velocities and accelerations that can be employed during biomechanical analysis to gain a better understanding of what occurs during activity. The focus of experimentation was baseball pitching and batting at the professional level. Several pitchers and batters were instrumented with the system and data was gathered during several pitches or swings. The data was analyzed, and the results of this analysis are presented in this thesis. The dynamic results are more precise than from other camera based systems and also offer the measurement of metrics that are not available from any other system, providing the opportunity for furthering sports medicine research. System performance and results are evaluated, and ideas for future work and system improvements are presented.

Pełny tekst źródłaBackground: Endurance athletes, in particular triathletes and ultra-distance runners, undergo high volumes of intense training in preparation for events. There is recent epidemiological evidence that the respiratory tract is the most common system affected by illness in athletes during tournaments. Respiratory tract symptoms have also been shown to affect endurance athletes particularly in the post- event period. However, the prevalence of respiratory related illnesses including respiratory tract symptoms, asthma, and allergies in the pre-race period has not been well studied in endurance athletes. Objective: The main aims of this dissertation were 1) to review the existing literature focussing on the epidemiology, pathogenesis, possible aetiology and management of respiratory tract symptoms, asthma and allergies in athletes, and 2) to conduct an investigation to determine the pre-event period prevalence (6 weeks and 1 week before an event) and nature of respiratory tract symptoms, asthma and allergies in Ironman triathletes and ultra-distance runners. Methods: In the first part of the dissertation, a review of the literature pertaining to respiratory tract symptoms and illness was undertaken. In the second part of the dissertation, a cross-sectional descriptive study was undertaken in 441 triathletes entering the 2006 and 2007 Ironman Triathlon, and 152 ultra- distance runners in the 2009 Two Oceans Ultra-marathon. In the 1 to 3 days before the race (registration period), participants were requested to complete a validated pre-event medical questionnaire containing sections on demographics, training and previous competition, common medical conditions and detailed sections on respiratory symptoms in the 6 weeks and 1 week period before the race, as well as asthma and allergies experienced. Respiratory symptoms were divided into upper respiratory tract symptoms (URTS), lower respiratory tract symptoms (LRTS) and systemic symptoms (SS). All data obtained regarding these respiratory related illnesses were compared between the triathlete group and the ultra- distance runners. Results: The main findings in the experimental section of the dissertation were that 1) triathletes trained significantly more hours in the 6 weeks and 1 week before an event than ultra-distance runners, 2) the period prevalence (6 weeks before the race) of respiratory tract symptoms was 50% of triathletes and 35% of ultra-distance runners, 3) upper respiratory tract symptoms and particularly nasal symptoms (nasal congestion and rhinorrhoea) were significantly more common in triathletes (21 to 27%) in comparison with ultra-distance runners (12 to 17%), 4) systemic symptoms (especially pyrexia) were significantly more common in ultra-distance runners in the 1 week before an event (9.2 vs. 2.4%), 5) the point prevalence of self-reported asthma was low in both study groups (ultra-distance runners 3.4% and triathletes 8.3%) although symptoms of dry cough, wheezing, shortness of breath and "tight" chest were reported by 25 to 80% of athletes in both study populations, 6) in most cases the diagnosis of asthma was made by means of history taking and a physical examination by a physician, 7) majority of triathletes used beta 2-agonists only as the treatment of choice for asthma symptoms, while ultra-distance runners used combinations of corticosteroids and beta 2-agonist inhalers as first line treatment, 8) allergies were reported by 34% of triathletes and 22.3% of ultra-distance runners, 9) most allergic symptoms in both study groups were confined to the upper respiratory tract with hay fever ranging from 77 to 83% and sinusitis 55 to 64.2%, and 10) the most common medication used for allergies by triathletes and ultra- distance runners, were anti-histamine tablets. Conclusion: There is a high period prevalence of respiratory symptoms in triathletes and ultra-distance runners in the 6 weeks before an endurance event. Triathletes had a significantly higher prevalence of upper respiratory tract symptoms (especially nasal symptoms) in comparison to ultra-distance runners, which might be related to allergies and a higher training volume. There also appears to be a lack in proper diagnostic evaluation of asthma in these endurance athletes with suboptimal and improper treatment of asthma and allergies. Approximately 10% of ultra-distance runners had systemic symptoms in the week before the event, indicating a lack of athlete education on possible risks of exercising with a systemic illness.

Pełny tekst źródłaUltra-endurance events, in particular Ironman Triathlons, are physically very demanding for the competitors. There is a large body of evidence showing the Upper Respitory Tract Symptoms (URTS) are very common in athletes in the 2-week period after such an event. However, there is no definitive explanation as t the exact cause of mechanism for the development of post-race URTS. The aims of this study were: (1) to determine the incidence of post-race URTS in triathletes competing in an Ironman Triathlon; (2) to identify clinical and immunological factors that are associated with the development of post-race URTS in these triathletes. In this prospective cohort study, 99 triathletes entering the 2006 South African Ironman Triathlon were recruited as subjects. All the subjects completed a validated questionnaire in the one to three days before the race (during registration). The questionnaire contrained sections on demographics, training history and previous performances, common general medical conditions that they may have experienced, and a detailed section pertaining to respiratory tracgt symptoms (RTS) and allergies. At registration, each subject had a blood sample taken for analysis of cytokines representing mainly a TH1 response (IL-2, and IL-12) (cell mediated immunity) and a TH2 response (IL-4, IL-6, IL-10) (humoral immunity), as well as a saliva sample (for salivary α-amylase, cortisol and IgA concentrations). Collection of blood and saliva samples was repeated immediately post-race. Data regarding race performance was collected within one week after completion of the race.

The effects of long-term participation in ultra-endurance exercise on the cardiovascular system have recently been the subject of much interest. It is well known that HRV, a marker of autonomic activity, is enhanced with long-term aerobic exercise training. However, after acute exercise, HRV is reduced, but recovers over time depending on the intensity of the prior bout of exercise. A limitation of previous research is that exercise bouts of only up to 120 minutes have been studied. A modified Stroop Task is a laboratory stressor to assess executive cognitive function by means of reaction time and accuracy. The resting HRV is directly related to these prefrontal neural functions, but the effect of an altered HRV on cognitive function has never been investigated. We determined the effects of an ultra duration (10 – 15 hours) exercise event on parameters of HRV and cognitive function during a Modified Stroop Task, 60 – 200 minutes after the 2007 South African Ironman Triathlon event (3,6km swim; 180 Km cycle; 42,2 Km run). 1 Female and 13 male competing triathletes (IRON; ages 33.7±7.9) and 7 control subjects (CON; 2 female and 5 males aged 42 ±4.5) completed a Modified Stroop Task before and after the event. The individual HRV parameters, heart rate (HR), respiratory frequency (RF), reaction time (RT) and % of mistakes made were recorded via the Biopac MP150WSW System (Goletta, California, USA). Data was transformed by auto regressive analyses (Biomedical signal analysis group, University of Kuopio, Finland) into LF (0.04 - 0.15 Hz) and HF (0.15 - 0.5 Hz) components. Additional calculations included %LF and %HF as well as the central or peak frequencies in both the LF and HF bands.

Pełny tekst źródłaExercise-associated muscle cramping (EAMC) is a common condition of spontaneous, painful skeletal muscle spasms that occur in exercising muscles during exercise or in the immediate post-exercise period. There is a high prevalence in endurance athletes, including ultra-distance triathletes. The exact cause for this condition has not been defined but various hypotheses have been proposed. Over the last decade the ""fatigue hypothesis"" has received most of the support in the scientific literature. Evidence from animal experiments, clinical studies on endurance athletes and situational information, suggest that neuromuscular fatigue may precede the increased neuromuscular excitability leading to EAMC. The objective of this research study was to identify factors associated with EAMC in endurance triathletes in an attempt to further elucidate the aetiology. Triathletes competing in the 2006 South African lronman triathlon were recruited as subjects in a prospective cohort study. A total of 44 triathletes made up the cramping group and 166 the non-cramping group. A detailed questionnaire, including information on training, personal best performances and a cramping history was completed by both groups of triathletes. Full clinical data was also collected from both groups. This included pre-and post race body weights, and pre- and post-race serum electrolyte concentrations. The main findings of the study were that the two independent risk factors for EAMC in these triathletes were a faster overall race time (and cycling time), and a past history of cramping (in the last 10 races). Results showed that EAMC was correlated with faster overall and cycle section times. The athletes who had experienced cramps in this event not only achieved taster race times but also predicted faster times, despite similarly matched preparation and performance histories as those who did not cramp. A higher intensity of racing would thus be required by these athletes, predisposing them to premature fatigue. The results thus agree with the ""fatigue hypothesis"" as an aetiological mechanism for EAMC. This study also showed no correlation between EAMC and changes in hydration status or changes in serum electrolyte concentration. This study thus adds to the evidence against disturbances in hydration and electrolyte balance as causes for cramping in exercise and further focuses attention on neuromuscular fatigue as a possible primary factor.

Pełny tekst źródłaTriathletes, in particular Ironman triathletes, undergo intense training and compete in a very physically demanding race. Medical conditions in the pre-race period in these triathletes have not been well documented, but there is evidence form other endurance sports that symptoms of respiratory tract infection are particularly common. However, the prevalence, causes and consequences of these symptoms have not been studied in Ironman triathletes. The aims of this study were: 1) to determine the incidence of respiratory tract symptoms (RTS) in triathletes preparing for an Ironman Triathlon, 2) to establish the factors associated with the development of these RTS, and 3) to determine the effects of the RTS on pre-race training and race performance. Methods: In this cross-sectional descriptive study, 304 triathletes entering the 2006 Ironman triathlon in South Africa were recruited as subjects. All the subjects completed a validated questionnaire in the 1-3 days before the race (during registration). The questionnaire contained sections on demographics, training and previous competitions, common general medical conditions that they may have experienced, and a detailed section pertaining to RTS and allergies, including use of medication. Data on race performance was collected after completion of the race. Subjects were divided into the following groups, based on their self-reported history of RTS in the 6 weeks period prior to the race: no RTS, all RTS, only upper respiratory tract symptoms (URTS), lower respiratory tract and/or systemic symptoms (LRT +SS).

Pełny tekst źródłaIt is well documented that participation in ultra-endurance events such as the Ironman Triathlon, can be associated with the development of post-race water and sodium imbalances in athletes. Variants within genes that encode for proteins that regulate thirst have been shown to be associated with weight changes during participation in an Ironman Triathlon. Recent evidence of mutations within the arginine vasopressin 2 receptor (AVPR2) gene, which encodes a constitutively active receptor in the collecting tubules of the kidney, resulted in increased water reabsorption and hyponatraemia in two unrelated male infants. This suggests that serum imbalances and hydration status in individuals participating in an endurance event may also be, in part, controlled by variants withink the AVPR2 gene. The aim of this study was to investigate whether polymorphisms within the AVPR2 gene are associated with exercise-associated serum sodium and/or water imbalances in triathletes who particpated in the 2006 South African Ironman Triathlon.
