Genetic Markers Associated with Power Athlete Status

polymorphic variants A1298C (rs1801131 A/C) of 5,10-methylenetetrahydrofolate reductase ( MTHFR ; location: 1p36.3), A2756G (rs1805087 A/G) of methionine synthase ( MTR ; location: 1q43), A66G (rs1801394 A/G) of methionine synthase reductase ( MTRR ; location: 5p15.31) genes were determined in athletes and control subjects. The frequencies of MTHFR rs1801131 C, MTR rs1805087 G and MTRR rs1801394 G alleles (probably associated with a reduced DNA methylation capacity) were significantly higher in athletes compared with controls ( Terruzzi et al., 2011 ).

Caffeine Supplementation for Powerlifting Competitions: an Evidence-Based Approach

directly in the context of strength performance, we may be able to draw some conclusions from studies using other exercise tests. Negaresh et al. (2019) investigated the effects of caffeine on combat performance in five matches consisting of 2 × 3-minutes of wrestling with 45 to 185 minutes of between-match rest intervals. Performance was examined under five different conditions: (a) placebo; (b) high-dose of caffeine (10 mg·kg −1 ) administered in one dose before the first match; (c) moderate dose of caffeine (4 mg·kg −1 ) delivered in the same fashion as 10 mg·kg −1

No Pain, No Gain? Prevalence, Location, Context, and Coping Strategies with Regard to Pain Among Young German Elite Basketball Players

by more than 10% of all participants in the last 7 days, and the frequency of this was significantly noticeable (χ 2 test; p < 0.05). The pain localizations highlighted in light gray (elbow and wrist) did not present simultaneous occurrence to any other localization . As young competitive athletes frequently experience pain in multiple areas, it is worth considering the area in which the pain experienced is most severe. At the time of the survey, 1 in 4 elite young basketball players reported knee and leg pain, while 1 in 6 specified back pain as the most
