Squash in Los Angeles: Heat Strain and Performance Considerations at the 2028 Olympic Games.

Background: The Los Angeles 2028 Olympics will mark the debut of squash, a high-intensity sport characterized by repeated efforts, posing potential thermoregulatory challenges. The demanding nature of squash results in substantial metabolic heat production, with consequential heat strain exacerbated by the indoor environment of squash courts, where low to moderate evaporative potential limits effective cooling. Players often experience increased body-heat storage and thermal strain, with muscle cramps (an early warning sign of more severe heat-related illnesses) commonly observed during tournaments.

How Does Blood-Flow Restriction Alter Forehand Drive Performance and Muscle Recruitment in Tennis Players?

Purpose: To examine the acute effects of forehand drive (FD) preconditioning with or without blood-flow restriction (BFR) on subsequent forehand performance and muscle recruitment in tennis.

Methods: On separate visits, 12 well-trained tennis players participated in 4 randomized trials. Each visit included pretests (maximal muscle-activation capacity or FD performance), a preconditioning phase, and posttests after 5 minutes of rest (ie, similar to pretests).

The role of exercise in restoring executive function: a comparison of tobacco-exposed college athletes and sedentary students.

Introduction: As adolescent smoking rates rise, its impact on cognitive function has drawn greater attention. This study explores whether exercise can mitigate the negative effects of smoking on executive function in male college students.

Methods: Sixty male college students were divided into four groups (n = 15 each): sedentary smokers, sedentary nonsmokers, athletic smokers, and athletic nonsmokers.
