161. Protein Supplementation and Muscle Recovery in Football

of Thessaly Study Details Study Description Go to Brief Summary: Soccer is an intermittent sport including a high number of powerful actions such as accelerations, decelerations, changes of direction, jumps and impacts that incorporate a strong eccentric component and may therefore lead to skeletal muscle damage. Indeed, match activity is associated with the onset of muscle damage and an acute inflammatory response that result in attenuated performance for as long as 1 to 3 days. In competitive soccer (...) though, multiple matches are performed within a small-time frame resulting in inadequate muscle recovery and reduced field performance. Supplementation with milk proteins following intense exercise protocols has been shown to stimulate protein synthesis and facilitate muscle recovery. Thus, the aim of the present investigation is to examine the effects of milk protein supplementation on muscle recovery and soccer-specific performance during an in-season microcycle with two matches performed three

167. [β-hydroxy-β-methylbutyrate as a dietary supplement (I): metabolism and toxicity]. (Abstract)

[β-hydroxy-β-methylbutyrate as a dietary supplement (I): metabolism and toxicity]. -hydroxy--methylbutyrate (HMB) is a leucine metabolite produced from -ketoisocaproic acid. HMB supplementation has been used as a dietary supplement in sports since 1997, with the aim of decreasing muscle proteolysis. In recent years, positive effects have been reported in different pathologies, which suggests potential health benefits.The objectives of this review are: to know both HMB metabolism (...) and toxicity, and to identify HMB cellular and molecular mechanisms of action when used as a dietary supplement.A search was performed in the Web of Science, Pubmed and SportDiscus data bases. RESULTS were divided into two parts; this article presents the results about both HMB metabolism and possible toxicity.Studies show that HMB is related to cholesterol metabolism in skeletal muscle, which could reduce proteolysis, through hydroxy-methyl-glutaryl-coenzyme A and mevalonate as a precursor

169. Decrease in Ionized and Total Magnesium Blood Concentrations in Endurance Athletes Following an Exercise Bout Restores within Hours-Potential Consequences for Monitoring and Supplementation. (Abstract)

Decrease in Ionized and Total Magnesium Blood Concentrations in Endurance Athletes Following an Exercise Bout Restores within Hours-Potential Consequences for Monitoring and Supplementation. Magnesium is essential for optimal sport performance, generating an interest to monitor its status in athletes. However, before measuring magnesium status in blood could become routine, more insight into its diurnal fluctuations and effects of exercise itself is necessary. Therefore, we measured the effect (...) performed a 90 min bicycle ergometer test (70% VO2max) between 11:00 and 12:30. Whole blood samples were analyzed for iMg and plasma for tMg concentrations. Both concentrations decreased significantly after exercise (0.52 ± 0.04-0.45 ± 0.03 mmol/L and 0.81 ± 0.07-0.73 ± 0.06 mmol/L, respectively, p < .001) while no significant decline was observed during that time-interval on control days. Both, iMg and tMg, returned to baseline, on average, 2.5 hr after exercise. These findings suggest that timing

170. Acute citrulline-malate supplementation improves maximal strength and anaerobic power in female, masters athletes tennis players. (Abstract)

Acute citrulline-malate supplementation improves maximal strength and anaerobic power in female, masters athletes tennis players. Citrulline-malate (CM) is a precursor to nitric-oxide (NO) in the NO synthase (NOS) pathway and is suggested to increase exercise performance in younger individuals. With age, NO production decreases and augmented NO production may provide beneficial effects on sports performance among masters athletes (MAs).To examine the effects of acute CM supplementation on grip (...) within trials, but no significant differences were observed between trials regarding supplement consumed.These data suggest that consuming CM before competition has the potential to improve tennis match-play performance in masters tennis athletes. However, this study utilized a controlled laboratory environment and research evaluating direct application to on-court performance is warranted.

171. Post-exercise branched chain amino acid supplementation does not affect recovery markers following three consecutive high intensity resistance training bouts compared to carbohydrate supplementation. (Full text)

Post-exercise branched chain amino acid supplementation does not affect recovery markers following three consecutive high intensity resistance training bouts compared to carbohydrate supplementation. Amino acid supplementation has been shown to potentially reduced exercise-induced muscle soreness. Thus, the purpose of this study was to examine if branched chain amino acid and carbohydrate (BCAACHO) versus carbohydrate-only sports drink (CHO) supplementation attenuated markers of muscle damage (...) while preserving performance markers following 3 days of intense weight training.Healthy resistance-trained males (n = 30) performed preliminary testing (T1) whereby they: 1) donated a baseline blood draw, 2) performed knee extensor dynamometry to obtain peak quadriceps isometric and isokinetic torque as well as electromyography (EMG) activity at 60°/s and 120°/s, and 3) performed a one repetition maximum (1RM) barbell back squat.

173. Effect of beta-alanine and sodium bicarbonate supplementation on repeated-sprint performance. (Abstract)

Effect of beta-alanine and sodium bicarbonate supplementation on repeated-sprint performance. This study aimed to investigate if combining beta alanine (BA) and sodium bicarbonate (NaHCO3) supplementation could lead to enhanced repeated-sprint performance in team-sport athletes, beyond what is possible with either supplement alone. Participants (n = 24) completed duplicate trials of a repeated-sprint test (3 sets; 6 × 20 m departing every 25 seconds, 4 minutes active recovery between sets (...) ) and for each individual set and for first sprint (sets 2 and 3) and best sprint time (sets 2 and 3). Combining BA and NaHCO3 resulted in "possible" to "likely" benefits for overall TST and for sets 2 and 3. First sprint (set 3) and best sprint time (sets 2 and 3) also showed "likely" benefit after this trial. The BA and placebo groups showed no differences in performance after supplementation. In conclusion, these results indicate that supplementation with acute NaHCO3 improved repeated-sprint performance

Effect of Beta-Alanine Supplementation on 2000 m Rowing Ergometer Performance. Beta-alanine supplementation has been shown to improve exercise performance in short-term high-intensity efforts. However, whether supplementation with beta-alanine is ergogenic to actual sporting events remains unclear and should be investigated in field testing or race simulations.The aim of this study was to assess if beta-alanine supplementation could improve 2,000-m rowing-ergometer performance in well-trained (...) male rowers.Participants (N = 16) completed duplicate trials (2 × before supplementation and 2 × after supplementation) of a 2,000-m rowing-ergometer race separated by 28 days of either beta-alanine (n = 7; 80 mg · kg-1 BM · d-1) or placebo (n = 9; glucose) supplementation.Beta-alanine group (pooled) race times improved by 2.9 ± 4.1 s and placebo group slowed by 1.2 ± 2.9 s, but these results were inconclusive for performance enhancement (p = .055, ES = 0.20, smallest worthwhile change = 49
