Article Synopsis
- The study examined how specific genetic variations (polymorphisms) impact athletic performance, focusing on Brazilian swimmers and their endurance and strength abilities.
- 123 elite and sub-elite athletes participated, with findings indicating a higher frequency of certain genotypes (like DD in ACE) among strength experts in elite groups.
- The results suggest that genetic factors like ACE and ACTN3 polymorphisms play a significant role in influencing athletic performance in swimmers, although no differences in overall allele distribution were found among athletes versus controls.
Background: This study aimed to analyze the extent of fatigue responses after female soccer matches and the ensuing recovery time course of performance, physiological, and perceptual responses.
Methods: Three databases (PubMed, Web of Science, and SPORTDiscus) were searched in October 2020 and updated in November 2021. Studies were included when participants were female soccer players, regardless of their ability level.
Objective: This study examined the effects of resistance training (RT) performed at 24 or 48h post-match on recovery in female soccer players.
Methods: In a randomized cross-over design, 10 professional female soccer players undertook matches followed by three conditions: Control (no RT), RT-24h and RT-48h post-match. RT was a high-speed and low-load session, consisting of 3 sets of 6 repetitions of lower-body exercises at 50%1RM.

This study determined the time-course of recovery after resistance training (RT) sessions and the association between changes in performance with changes in biomechanical, physiological and perceptual parameters. After a 4-week familiarization period, 14 resistance-trained males performed 3 experimental conditions, each one including 2 sessions with a recovery interval of 24, 48 h or 72 h, in a randomized order. RT sessions consisted of 5 sets of 8-10RM on squat and leg press exercises.

Studies were identified from a systematic search of three databases (PubMed, Web of Science, and SportDiscuss), with search phrases constructed from MeSH terms, alone or in combination, limited to English-language literature, and published up to January 2016. Our main findings were that variables related to external load (distance, speed, and duration) are used to monitor load in competition.

Methods:: Cross-sectional study, carried out in Itaúna-MG, in 2010, with 290 school children ranging from 6 to 10 years-old of both sexes, randomly selected. Children from schools located in the countryside and those with medical restrctions for physical activity were not included.
