Relative age effects on speed trials in Brazilian athletics.

Background: Relative age effect (RAE) is a concept related to the possible advantage that older athletes would have over younger ones within the same category. Although many studies have approached this subject in individual sports, there are few clippings by events within the sport. More detailed analyses are necessary for a better understanding of how RAE behaves in sports, especially in athletics, the subject of this study.

Relative age effect in elite Brazilian athletes in different combat sports: an observational study.

Background: The relative age effect (RAE) suggests that, due to maturity, young athletes born in the first quartiles of the year may have advantages over those born in the last quartiles of the year. Thus, it is important to evaluate the RAE in different sports and to consider the particularities of the subdivisions of the sports categories.

Objective: To analyze the RAE in the top 20 of the Brazilian rankings in different combat sports.

A cloth facemask increased ratings of perceived exertion and reduced affect, without affecting sprint or muscular performance.

We determined the effects of wearing a cloth facemask on exercise performance and subjective responses during training of track and field athletes. Track and field athletes (n = 10, sprinters and long jumpers) performed two training sessions with and without a three-layered antiviral cloth facemask. The training session simulated the specific demands of the sport, consisting of five 30-m sprints, interspersed with passive 4-min intervals.

Equation for analyzing the peak power in aquatic environment: An alternative for olympic rowing athletes.

Purpose: To develop an equation to provide the peak power (PP) through a specific stimulus performed in an aquatic environment, as well as to correlate morphological, anthropometric and strength variables with rowing performance.

Methods: The sample consisted of 16 elite young rowing athletes of both sexes (15.7 ± 1.
