Abstract:
Introduction: To avoid injuries during high-intensity sports training, it is important to recognize conditions of bodily consumption and production of adequate energy; exercise increases the concentration of the blood lactate. This paper is an attempt to compare pre and post lactate tolerance exercise test - blood lactate concentrations - of elite boy swimmers. Methods: Blood lactates are measured by an enzymatic method on 12 subjects 30 minutes before and adjust and 24 hours after the test. Results: The mean lactate concentration of 30.35±12.16 mg/dl is observed in swimmers 30 minutes before the test. Swimmers adjust after the test show mean blood lactate concentration of 108.52±18.17 mg/dl that is significantly higher than 30 minutes before the test (p<0.001). Then blood lactate level decreases below baseline level at 24 hours after the test. Conclusion: Blood lactate increases with the test and decreases below baseline within 24 hours after the test.

Abstract:
The purpose of this investigation was to identify the intensity of recovery exercise, relevant to endurance event performance, that would result in the most rapid times for half decrease in blood lactate concentration, following 2 minutes of cycling at maximal rates. Three recovery exercise intensities were investigated: (a) 7% of the maximal rate of oxygen consumption (VO$\sb2$) (LT $-$7%), (b) lactate threshold VO$\sb2$ ( LT), and (c) 7% of VO$\sb2$max above lactate threshold VO$\sb2$ (LT +7%). Seven well-trained male cyclists (mean VO$\sb2$max 4.6 $\pm$ 0.49 L $\times$ min$\sp{-1}$ participated as subjects in the investigation. Each subject completed seven separate cycling tests: (a) one combined lactate threshold-VO$\sb2$max test, (b) three constant work rate tests, and (c) three tests of recovery following supra-lactate threshold exercise (surge-recovery tests). The absolute values of blood lactate concentration were significantly different across the three recovery intensities (p .01). At the end of the 20 minute recovery period the mean blood lactate concentrations were 1.57, 2.49, and 4.17 mmol $\times$ L$\sp{-1}$ for the LT $-$7%, LT%, and LT +7% recovery intensities, respectively. Times for half decrease in blood lactate concentration were calculated. There were no significant differences in these half decrease times between the three recovery intensities (p .01).

Abstract:
PURPOSE: To compare the effects of recovery intensity on performance of a bicycle sprint task and blood La⁻ clearance. METHODS: On three separate days twelve trained male subjects (27.4 ± 3.9 yrs) performed three supramaximal exercise (SE) bouts at 120% of maximum aerobic power (MAP) for 60% of the time to exhaustion (TTE). Bouts were separated by 5 mm of passive recovery (PR), active recovery (AR) or combined active recovery (CAR). The third bout was followed by a 14 mm recovery. Recovery intensities were: PR (rest), AR at 50% of the workload difference between the individual anaerobic threshold (IAT) and the individual ventilatory threshold (IVT) below the IVT ( ₋50%ΔT), or CAR at the IAT workload for 5 mm and at the ₋50%ΔT workload for 9 mm. Five 10 s sprints were performed 2 mm post-recovery. Blood lactate (La⁻) concentration, power parameters (Peak Power (PP), Mean Power (MP), Fatigue Index (Fl), and Total Work (TW)), Heart Rate (HR), and Oxygen Uptake (VO₂‚‚) were compared using repeated-measures ANOVA. Pairwise comparisons and dependent T-tests were performed to analyze differences. RESULTS: Mean La⁻ values for AR and CAR were lower than PR (9.7 ± 3.5, 9.5 + 3.5, 11.7 + 3.6, respectively, p≤0.05). La⁻ was significantly lower with CAR versus PR at the 3rd, 6th, 9th, and 14th mm of recovery (p≤0.05). AR versus PR La⁻ was lower at the 3rd, 6th, 9th, and 14th min of recovery (p≤0.05). Mean MP was greater in the AR group compared to the PR group (800.1 ± 114.5 vs 782.2 ± 111.7 W, p≤0.05). TW during AR was greater than PR (p≤0.05) but not CAR (p≤0.05, 40003.3 ± 5110.2, 39108.3 ± 4852.9, 39335.8 ± 5022.6 J, respectively). CONCLUSIONS: AR and CAR both demonstrated improved La⁻ clearance when compared to PR, but differences in La⁻ clearance did not determine performance on the sprint task. AR resulted in more TW than PR and greater maintenance of power over the sprints.

Full text
Abstract:
(1) Background: Maximum isokinetic force loads show strongly increased post-load lactate concentrations and an increase in the maximum blood lactate concentration rate ( V˙ Lamax), depending on load duration. The reproducibility of V˙ Lamax must be known to be able to better assess training-related adjustments of anaerobic performance using isokinetic force tests. (2) Methods: 32 subjects were assigned to two groups and completed two unilateral isokinetic force tests (210° s−1, Range of Motion 90°) within seven days. Group 1 (n = 16; age 24.0 ± 2.8 years, BMI 23.5 ± 2.6 kg m−2, training duration: 4.5 ± 2.4 h week−1) completed eight repetitions and group 2 (n = 16; age 23.7 ± 1.9 years, BMI 24.6 ± 2.4 kg m−2, training duration: 5.5 ± 2.1 h week−1) completed 16 repetitions. To determine V˙ Lamax, capillary blood (20 µL) was taken before and immediately after loading, and up to the 9th minute post-load. Reproducibility and variability was determined using Pearson and Spearman correlation analyses, and variability were determined using within-subject standard deviation (Sw) and Limits of Agreement (LoA) using Bland Altman plots. (3) Results: The correlation of V˙ Lamax in group 1 was r = 0.721, and in group 2 r = 0.677. The Sw of V˙ Lamax was 0.04 mmol L−1 s−1 in both groups. In group 1, V˙ Lamax showed a systematic bias due to measurement repetition of 0.02 mmol L−1 s−1 in an interval (LoA) of ±0.11 mmol L−1 s−1. In group 2, a systematic bias of −0.008 mmol L−1 s−1 at an interval (LoA) of ±0.11 mmol L−1 s−1 was observed for repeated measurements of V˙ Lamax. (4) Conclusions: Based on the existing variability, a reliable calculation of V˙ Lamax seems to be possible with both short and longer isokinetic force loads. Changes in V˙ Lamax above 0.11 mmol L−1 s−1 due to training can be described as a non-random increase or decrease in V˙ Lamax.

Abstract:
The purpose of this investigation was to examine the change in pulmonary ventilation (V_E), ventilatory equivalent of oxygen (VE_O_2) and lactic acid (LA) in relation to oxygen uptake (V_O_2) as predictors of the lactate threshold (LT). Eight healthy male (21.9 ± 3.0 years) subjects conducted three incremental-load tests. In each test the initial work rate consisted of 4 minutes of unloaded pedaling ("0" load) followed by incremental-load work of 360 Kgm • min^-1 at 60 rpm for trial I and trial II, while during trial III the work rate consisted of 540 Kgm • min^-1 of incremental-load work at 90 rpm. Work load was increased every third minute until the subject reached voluntary exhaustion. Blood samples from a forearm vein were collected during trial II (60 rpm) and trial III (90 rpm) and analyzed for lactic acid. In our subjects the measured (x̄ ± SD) lowest VE_O_2 for O_2 in relation to V_O_2 for trial I of 22.9 ± 1.9 occurred at a V_O_2 of 1.27 ± 0.8 L • min^-1. For trial II the VE_O_2 of 22.4 ± 1.3 occurred at a V_O_2 of 1.30 ± 0.09 L • min^-1, while for trial III a VE_O_2 of 24.4 ± 2.5 occurred at a V_O_2 of 1.84 ± 0.15 L • min^-1. The lowest VE_O_2 and onset of LA accumulation as calculated from individual exponential equations relating V_E to V_O_2 yielded V_O_2 values at 1.77 ± 0.18 L • min^-1 and 1.74 ± 0.25 L • min^-1 for trial II, and 1.83 ± 0.19 L • min^-1 and 2.02 ± 0.53 during trial III. Utilizing ln[LA]-ln V_O_2 equations, the LT occurred at a V_O_2 of 1.30 ± 0.07 L • min^-1 during trial II and 1.85 ± 0.12 L • min^-1 during trial III. It was concluded that during the 60 rpm test that the lactate threshold was best predicted by measured lowest VE_O_2 and the plot of the In[LA] to In V_O_2 relationship. The methods used in this study provide a valid and reliable estimate of the lactate threshold and support the use of measured lowest VE_O_2 , a respiratory gas exchange measure, as an indirect measure of the lactate threshold.

Abstract:
The purpose of this study was to observe the differences in rates of blood lactate reduction (BLR) at three recovery intensities (40% VO₂max, 60% V02max, and combined recovery ) when subjects are highly trained and aerobically fit. Eight well-trained oarsmen (age = 23.2 yr, Ht = 189.6 cm, Wt = 85.3 kg, VO₂max = 5.2 1 / min or 61.6 ml / kg min⁻¹) were tested in one pre-experimental procedure and three experimental treatments. The pre-experimental procedure involved the determination of VO₂max, and the loads at which 40 -, 50 -, and 60% VO₂max occurred from a progressive load VO₂max. The three experimental treatments each involved three one minute maximal load intervals on the rowing ergometer to elevate blood lactate, followed by a 30 minute randomly assigned recovery on the rowing ergometer at either 40% VO₂max (40R), 60% VO₂max (60R), or combined recovery (CR). Blood samples, from an indwelling catheter placed in the cephalic vein, were taken at t=0,1, 2, 3, 4, 5, 6, 9,12,15,18, 21, 24, 27, and 30 min of recovery. Analysis of plasma samples revealed a mean resting blood lactate concentration ( [ Bla ] ) of 1.2 mM and a mean peak [ Bla ] following maximal exercise of 16.3 mM. ANOVA indicated that no significant differences occurred between the rates of lactate reduction for the three treatments (p<.055). With p<.055 and an effect size of eta=.31, further testing using a post-hoc multicomparison analysis revealed a significantly faster (p<.05) rate of BLR during the 60R treatment when compared to the rate of BLR for 40R. No further differences were revealed between any of the other comparisons (40R vs CR, or 60R vs CR). The significant differences between the rate of BLR for 60R compared to 40R may be due to the subjects' high aerobic fitness, the specific nature of both their training and the recovery task, and physiological adaptations related to a high fitness level.

Abstract:
This study examined the relationship between expired non-metabolic CO₂ (EX CO₂) and the accumulation of blood lactate, while emphasis was placed on the ventilatory (EX CO₂ and VE/VO₂) and lactate threshold relationship. Twenty-one elite cyclists (15 males, 6 females) performed a progressive intensity bicycle ergometer test (PIT) during which ventilatory parameters were monitored on-line at 15 second intervals, and blood lactate sampling occured on each minute. Threshold values were determined for each of the three indices; excess CO₂ (EXTT), VE/V0₂ (VVTT), and blood lactate (LATT). The three threshold values (EXTT, VVTT, LATT) all correlated significantly (P<0.001) when each was expressed as an absolute VO₂ (1/min). A significant RM ANOVA (F=8.41, P<0. 001) and post hoc correlated t-tests demonstrated significant differences between the EIXTT and LATT (P<0.001) and the EXTT and VVTT values (P<0.025). The LATT occured at an average blood lactate concentration of 3.35 mmol/1, while the mean expired excess CO₂ volume at the EXTT was 14.04 ml/kg/min. Over an 11 minute range across the threshold values (EXTT and LATT), which were used as relative points of reference, the expired EXC02 volume (ml/kg/min) and blood lactate concentration (mmol/1) correlated significantly (r=0. 69, P<0. 001).

Abstract:
Occupational compression sleeves are commonly used to relieve pain in the upper and lower extremities. Anecdotal data agree on the benefits of using compression sleeves while performing physical work. The purpose of this study was to assess the effects of wearing compression sleeves on the upper limbs on blood lactate concentration while completing a physically demanding activity. This study included six college-age participants from the University of Texas at El Paso. Anthropometric measurements were taken before the beginning of the study. Afterward, each participant’s basal capillary blood lactate level was established by averaging lactate concentration from three consecutive days. Capillary blood samples were taken from the participant’s earlobe, and lactate concentration (mmol/L) was assessed using the Lactate Plus Lactate Analyzer (Nova Biomedical). After obtaining all the baseline measurements, each participant completed six simulated work sessions, one with sleeves and another without sleeves, at an intensity of 25 Watts, 50 Watts, and 75 Watts a cadence of 60 RPM, and 10 minutes of duration. All participants rested for at least 72 hours between sessions to prevent muscular fatigue effects of lactate concentrations. The use of compression sleeves showed an average reduction of lactate concentration of 0.2 mmol/L. This study shows the potential benefits of wearing compression sleeves while performing activities involving the upper limbs by helping prevent lactate accumulation, a common indicator of muscular effort.

ABSTRACT After several years of investigations of the training load in rhythmic gymnastics unification of testing in the field is need-ed. The aim is to implement a protocol for monitoring the physiological parameters. Two high-level rhythmic gymnasts aged 17 (Seniors) took part in this study. The physiological changes of the gymnasts were followed by measuring HR and blood lactate. At first, we tested the minute at which the peak of the blood lactate concentration appeared in order to take only one sample after the routines. In the literature different minutes are given to assess the peak value. Heart rate was recorded during each training for the duration of one micro cycle (a week) and the heart rate and the blood lactate were tested on a certain day of the week (Wednesday) for the duration of one mesocycle (month). The testing was carried out at the end of the preparatory and the beginning of the competitive period. The aim was to check the reliability of the testing with high-level athletes and to implement it into practice. The peak values of the heart rate and blood lactate were taken a few times during the training – before the start of the training; after the warm-up; before 1st routine (specific warm-up with apparatus); after the first, middle, and last routine of the day. The aim was to reduce the number of blood samples taken for each gymnast during the training sessions and also to optimize and simplify the procedure of the testing. With the implementation of this protocol in practice, it will be much more accurate to make a comparison among gymnasts or between the periods of the preparation for the same athlete. However, pilot studies should not be used to test hypotheses. Since the appropriate level in elite sport is measured we consider carrying on with further testing with a bigger number of gymnasts to prove the results.

Abstract:
ABSTRACT Periodization and planning of the training load is an essential process in the preparation of an elite gymnast. On the one hand, the coaches and gymnasts have to achieve the necessary level (individual maximum) of the volume (quantity of elements and routines), and on the other hand, they have to do it at the “right time”. Last but not least is to prevent the gymnasts from injuries. That is why we need to study the dynamic of the training load from a physiological point of view and should have a better understanding of how the body’s system responds. This study aims to observe body reactions to the training load during one microcycle and one mesocycle in acrobatics gymnastics. One female youth Olympic champion (18 years old) and one male bronze medallist from junior WCH (26 years old) were tested. The study was made at the end of the preparation period and the beginning of the competitive period. The indicators measured were HR, blood La. Heart rate was recorded by Suunto Ambit 2. A drop of blood sample was taken from the fingertip to assess the average peak blood lactate concentration using an Accutrend Plus Roche. A heart rate record was made during one week of training (6 training days). Monitoring of the blood La took place once a week (every Thursday) for one month. The obtained results show how the gymnast body’s systems react to the training load in microcycles and mesocycle in acrobatics gymnastics. The data allow timely optimization of the training load and is a prerequisite for the improvement of the next periodization and planning of the training load not only for gymnasts that were tested but also for high-level gymnasts (Mixed Pair) with similar age and anthropometric indicators.

Abstract:
Original objectivesThe objectives of this project were to evaluate the growth performance, meat yield and quality attributes of broiler strains widely differing in their genetic potential under normal temperature vs. warm temperature (short and long-term) conditions. Strain differences in breast muscle accretion rate, metabolic responses under heat load and, gross and histopathological changes in breast muscle under thermal load was also to be characterized. BackgroundTremendous genetic progress has been made in broiler chicken growth rate and meat yield since the 1950s. Higher growth rate is driven by higher rates of feed intake and metabolism, resulting in elevated internal heat production. Hot rearing conditions negatively affect broiler growth by hindering dissipation of heat and may lead to a lethal elevation in body temperature. To avoid heat-induced mortality, broilers reduce feed intake, leading to depressed growth rate, lower weight gain, reduce breast meat yield and quality. Thus, the genetic potential of contemporary commercial broilers (CCB) is not fully expressed under hot conditions. Major conclusions, solutions, and achievementsResearch conducted in Israel focused on three broiler strains – CCB, Featherless, Feathered sibs (i.e., sharing similar genetic background). Complimentary research trials conducted at Auburn utilized CCB (Cobb 500, Cobb 700, Ross 308, Ross 708), contrasting their performance to slow growing strains. Warm rearing conditions consistently reduced feed intake, growth rate, feed efficiency, body weight uniformity and breast muscle yield, especially pronounced with CCB and magnified with age. Breast meat quality was also negatively affected, as measured by higher drip loss and paler meat color. Exposure to continuous or short-term heat stress induced respiratory alkalosis. Breast muscle histomorphometrics confirmed enhanced myofiber hypertrophy in CCB. Featherless broilers exhibited a significant increase in blood-vessel density under warm conditions. Rapid growth and muscle accretion rate was correlated to various myopathies (white striping, woody and necrotic) as well as to increases in plasma creatinekinase levels. Whether the trigger(s) of muscle damage is loss of cellular membrane integrity due to oxidative damage or tissue lactate accumulation, or to loss of inter-compartmental cation homeostasis is yet to be determined. Based on genome-wide single-nucleotide polymorphism array genotyping, identification of the gene with the recessive mutation Scaleless (sc) facilitated the development a dCAPS assay to discriminate between sc carrier (sc/+) and non-carrier (+/+) individuals. ImplicationsThis project confirmed that featherless broiler strains grow efficiently with high yield and quality of breast meat, even under warm rearing conditions that significantly depress the overall performance of CCB. Therefore, broiler meat production in hot regions and climates can be substantially improved by introducing the featherless gene into contemporary commercial broiler stocks. This approach has become more feasible with the development of dCAPS assay. A novel modification of the PCR protocol (using whole blood samples instead of extracted DNA) may contribute to the efficient development of commercial featherless broiler strains. Such strains will allow expansion of the broiler meat production in developing countries in warm climates, where energy intensive environmental control of rearing facilities are not economical and easily achievable.
