Purpose: This study examined the effects of overnight sleep deprivation on recovery after competitive rugby league matches. Methods: Eleven male amateur players played 2 matches, followed by either a normal night’s (~8 h; CONT) or sleep-deprived night (~0 SDEP) in randomized fashion. Testing was conducted morning match, immediately postmatch, h and next (16 postmatch). Measures included countermovement-jump (CMJ) distance, knee-extensor maximal voluntary contraction (MVC) activation (VA),...

Purpose: This study aimed to assess the effects of precooling volume on neuromuscular function and performance in free-paced intermittent-sprint exercise heat. Methods: Ten male, team-sport athletes completed four randomized trials involving an 85-min protocol 33°C ± 33% relative humidity. Precooling sessions included whole body (WB), head + hand (HH), (H), no cooling (CONT) applied for 20 min before 5 during exercise. Maximal voluntary contractions were assessed after intervention Exercise...

This study examined the effects of post‐exercise cooling on recovery neuromuscular, physiological, and cerebral hemodynamic responses after intermittent‐sprint exercise in heat. Nine participants underwent three trials, including a control ( CONT ), mixed‐method MIX cold‐water immersion (10 ° C ; CWI ). Voluntary force activation were assessed simultaneously with oxygenation (near‐infrared spectroscopy) pre‐ post‐exercise, post‐intervention, 1‐h 24‐h post‐exercise. Measures heart rate, core...

The aim of this study was to investigate the effect court surface (clay vs. hard court) on technical, physiological, and perceptual responses on-court tennis training. Four high-performance junior male players performed 2 identical training sessions clay courts, respectively. Sessions included both physical conditioning technical elements as led by coach. Each session filmed for later notational analysis stroke count error rates. Furthermore, wore a global positioning satellite device...

The use of personal cooling systems to mitigate heat strain on first-responders achieves two potential performance benefits relative the absence such cooling: 1) completion a workload with less effort; and/or 2) greater for same effort. Currently, claims made by manufacturers regarding capability their products in conjunction chemical/biological protective clothing remain largely unsubstantiated. purpose this investigation was evaluate means which can be alleviated during uncompensable...

This study examined the effects of core and muscle temperature on force steadiness motor unit discharge rate (MUDR) variability after a hot-water immersion session. Fifteen participants (6 women; 25 ± 6 years) completed neuromuscular assessments before either 42 °C (hot) or 36 (control) water immersion. Force was measured during knee extension, while HD-sEMG signals were recorded from vastus lateralis medialis for MUDR analysis. Following immersion, decreased by 0.11% (p < 0.05; d = 0.38)...

Generative AI (GenAI) offers transformative potential for exercise and sports science education, addressing traditional data analysis visualisation barriers while promoting real-world learning. This perspective article explores how integrating GenAI into degrees can enhance students' ability to interpret complex physiological data, improve their analytical skills, foster creativity in problem-solving. By automating routine technical tasks such as cleaning visualisation, allows students focus...

The world is experiencing increased frequency, duration, and severity of life-threatening heat extremes. Most hospitalizations excess deaths during extreme events are associated with preexisting diseases in older adults. As climate change persists, the global population ages number individuals chronic expands, more people at risk adverse health outcomes events. Therefore, proactive preventive measures urgently needed to mitigate heat-related risks within these populations. In this context,...

Purpose: Investigations into the specificity of rugby union training practices in preparation for competitive demands have predominantly focused on physical and physiological demands. The evaluation contextual variance perceptual strain or skill requirements between matches is unclear, yet holistic understanding may assist to optimize design. This study evaluated physical, physiological, perceptual, sessions compared with match play preprofessional, elite club union. Methods: Global...

This investigation examined physiological and performance effects of cooling on recovery medium-fast bowlers in the heat. Eight, completed two randomised trials, involving sessions consecutive days (Session 1: 10-overs Session 2: 4-overs) 31 ± 3°C 55 17% relative humidity. Recovery interventions were administered for 20 min (mixed-method vs. control) after 1. Measures included bowling (ball speed, accuracy, run-up speeds), physical demands (global positioning system, counter-movement jump),...

Abstract This study examined physiological and performance effects of pre-cooling on medium-fast bowling in the heat. Ten, bowlers completed two randomised trials involving either cooling (mixed-methods) or control (no cooling) interventions before a 6-over spell 31.9±2.1°C 63.5±9.3% relative humidity. Measures included (ball speed, accuracy run-up speeds), physical characteristics (global positioning system monitoring counter-movement jump height), (heart rate, core temperature, skin...
