Effects of low-volume court-based sprint interval training on aerobic capacity and sport-specific endurance performance in competitive tennis players.

Sprint interval training (SIT) is a potent exercise strategy to enhance athletes' aerobic capacity in a time-efficient manner. The purpose of this study was to examine the effect of a low-volume court-based SIT program on aerobic capacity and sport-specific endurance performance for competitive tennis players. Sixteen competitive collegiate tennis players were randomly assigned to the SIT (court-based repeated-sprint training) and traditional endurance training (ET; 45-min continuous treadmill running) groups for a 6-week intervention (3 sessions/week).

High-intensity interval training for improving cardiometabolic health in children and adolescents: An umbrella review of systematic reviews.

High-intensity interval training (HIIT) is an emerging exercise strategy to improve health and fitness, but previous studies have evaluated HIIT interventions across different populations and outcomes. This review aimed to comprehensively synthesize published evidence on the effects of HIIT on key cardiometabolic health parameters in children and adolescents. We searched seven databases until February 2024.

Context: Recent studies suggest that light-intensity physical activity may enhance cardiometabolic health and reduce mortality risk in adults. However, more information is required to understand the patterns of light-intensity physical activity and postprandial cardiometabolic health.

Objective: This study examined the effects of different light-intensity walking patterns on postprandial cardiometabolic responses in young obese adults.

Exploring the ergogenic potential of carbohydrate-caffeine combined mouth rinse on exercise and cognitive performance: a systematic review.

Carbohydrate (CHO) and caffeine (CAF) mouth rinsing have been independently reported to benefit sport performance. The proposed mechanisms by which mouth rinsing CHO exerts an influence are reported to be different from those for mouth rinsing CAF. However, the potential ergogenic effects of combining CHO and CAF in a single mouth rinse solution, are unclear.

The objective of the review was to assess the effects of NMN supplementation on fasting glucose, triglycerides, total cholesterol, LDL-C, and HDL-C in adults.

"Still work?" Design and effect of interventions used to modify feeding problems in children with autism: A systematic review of studies employing group designs.

Background: Feeding problems in children with autism jeopardize the well-being of both children with autism and their families. Mixed findings were reported from previous interventions, which were mostly evaluated by single subject research design (SSRD) studies. Moreover, feasibility assessment and social validity measurement were unaddressed by these SSRD studies.

Background: This study investigated the acute effects of various doses of nitrate-rich beetroot juice on the responses to high-intensity interval exercise in women.

Methods: A double-blinded, randomized, placebo-controlled, crossover trial was conducted with 13 recreationally active young women (age = 23 ± 2 years). All participants performed interval exercise (8 × 1-min bouts of cycling at 85% of peak power output [PPO] interspersed with 1-min active recovery at 20% of PPO) 2.

Music Timing Differentiates Fatigue Perception and Performance during Isometric Strength Exercises: A Crossover Randomised Trial.

Music is well-known to elicit ergogenic effects on exercise performance; however, the moderating role of application timing remains unclear.

A scoping review of physical activity-based interventions for obesity management in children and adolescents during the COVID-19 pandemic.

Overweight and obesity have emerged as global health issues among children and adolescents. Restrictions related to the COVID-19 pandemic have aggravated the threat of paediatric obesity due to the prevalent reduction in physical activity (PA) in children and adolescents. However, this has also created an opportunity for healthcare professionals to explore new strategies to address this persistent problem.

Comparing the Effectiveness of Physical Exercise Intervention and Melatonin Supplement in Improving Sleep Quality in Children with ASD.

Purpose: Previous studies have demonstrated that physical exercise can modulate the endogenous melatonin level in children with autism spectrum disorder (ASD) and improve their sleep quality. However, it remains unclear whether physical exercise or melatonin supplement, or a combination of both, is more effective in improving sleep quality in this population. The purpose of this study is to answer this research question by comparing the effectiveness of three types of interventions (physical exercise vs.
