Context:Although body cooling has both performance and safety benefits, knowledge on optimizing cooling during specific sport competition is limited.Objectives:To identify when, during sport competition, it is optimal for body cooling and to identify optimal body-cooling modalities to enhance safety and maximize sport performance.Evidence Acquisition:A comprehensive literature search was conducted to identify articles with specific context regarding body cooling, sport performance, and cooling modalities used during sport competition. A search of scientific peer-reviewed literature examining the effects of body cooling on exercise performance was done to examine the influence of body cooling on exercise performance. Subsequently, a literature search was done to identify effective cooling modalities that have been shown to improve exercise performance.Evidence Synthesis:The cooling modalities that are most effective in cooling the body during sport competition depend on the sport, timing of cooling, and feasibility based on the constraints of the sports rules and regulations. Factoring in the length of breaks (halftime substitutions, etc), the equipment worn during competition, and the cooling modalities that offer the greatest potential to cool must be considered in each individual sport.Conclusions:Scientific evidence supports using body cooling as a method of improving performance during sport competition. Developing a strategy to use cooling modalities that are scientifically evidence-based to improve performance while maximizing athlete’s safety warrants further investigation.

Moderate Effect

Beta-alanine supplementation has been shown to improve exercise performance in short-term, high-intensity efforts.Purpose:The aim of this study was to assess if beta-alanine supplementation could improve 800 m track running performance in male recreational club runners (n = 18).Methods:Participants completed duplicate trials (2 presupplementation, 2 postsupplementation) of an 800 m race, separated by 28 days of either beta-alanine (n = 9; 80 mg·kg−1BM·day−1) or placebo (n = 9) supplementation.Results:Using ANCOVA (presupplementation times as covariate), postsupplementation race times were significantly faster following beta-alanine (p = .02), with post- versus presupplementation race times being faster after beta-alanine (–3.64 ± 2.70 s, –2.46 ± 1.80%) but not placebo (–0.59 ± 2.54 s, –0.37 ± 1.62%). These improvements were supported by a moderate effect size (d = 0.70) and a very likely (99%) benefit in the beta-alanine group after supplementation. Split times (ANCOVA) at 400 m were significantly faster (p = .02) postsupplementation in the beta-alanine group, compared with placebo. This was supported by large effect sizes (d = 1.05–1.19) and a very likely (99%) benefit at the 400 and 800 m splits when comparing pre- to postsupplementation with beta-alanine. In addition, the first and second halves of the race were faster post- compared with presupplementation following beta-alanine (1st half –1.22 ± 1.81 s, likely 78% chance of benefit; 2nd half –2.38 ± 2.31 s, d = 0.83, very likely 98% chance of benefit). No significant differences between groups or pre- and postsupplementation were observed for postrace blood lactate and pH.Conclusion:Overall, 28 days of beta-alanine supplementation (80 mg·kg-1BM·day-1) improved 800 m track performance in recreational club runners.

Probiotics are increasingly being used as a nutritional supplement by athletes to improve exercise performance and reduce post-exercise fatigue. Lactobacillus salivarius is a natural flora in the gastrointestinal tract of humans and animals. Lactobacillus salivarius subspecies salicinius (SA-03) is an isolate from the 2008 Olympic women’s 48 kg weightlifting gold medalist’s gut microbiota. In this study, we investigated its beneficial effects on physical fitness. Male ICR mice were divided into four groups (n = 10 per group) and orally administered with SA-03 for 4 weeks at 0, 2.05 × 109, 4.10 × 109, or 1.03 × 1010 CFU/kg/day. Results showed that 4 weeks of SA-03 supplementation significantly improved muscle strength and endurance performance, increased hepatic and muscular glycogen storage, and decreased lactate, blood urea nitrogen (BUN), ammonia, and creatine kinase (CK) levels after exercise. These observations suggest that SA-03 could be used as a nutritional supplement to enhance exercise performance and reduce.
