This study aimed to test the reproducibility of the 3-min all-out effort applied using shuttle running and compare its values to aerobic parameters. On the first day, 14 futsal players underwent an exhaustive test to determine the maximal incremental speed (MIS) and anaerobic threshold (AnT). On the second day, the participants performed the 3-min all-out effort (n=14), which was repeated after 48 h (third day) to test its reproducibility (n=11).

Maximum isometric handgrip strength (MIHS) is a relevant parameter for judo performance and is related to health. Understanding the association between MIHS and MIHS relative (MIHSrel) and the absolute lean mass of the arm (LMarm) and the percentage of body fat (%BF) can provide important information for performance and health. The study aimed to investigate the correlation between MIHS and MIHSrel with the LMarm and the %BF of young judokas (sub-19, 15 males and 14 females).

The primary aim of this study was to compare the measured oxygen consumption (MeasuredO) in a simulated futsal game (S-Game) with the estimated oxygen consumption (EstimatedO) through a regression equation between heart rate (HR) and oxygen consumption (O) (HR-O) in treadmill running, and a secondary aim was to calculate the total energy expenditure (EE) in S-Game. Ten professional players (22.20 ± 3.

Article Synopsis
  • The study aimed to compare physiological responses (heart rate and blood lactate levels) of futsal players during the first half (1-H) and second half (2-H) while considering their on-court time during substitutions.
  • Results showed no significant differences in heart rate and blood lactate levels between the two halves, though there were variations in time spent in specific heart rate intensity zones.
  • The findings suggest that with proper substitutions and time management, players can maintain similar match intensity levels in both halves, providing valuable insights for coaches and future research.
