Abstract This study determined whether precooling would have an additive effect on repeat-sprint cycling performance in heat following partial acclimation. Ten males completed three trials; Pre Acclimation (Pre Acc) and two Post trials, one with (ice jacket slushy; Acc +PC) another without (Post Acc). Trials consisted of a 30-min baseline period followed by 70-min protocol ∼35°C 60% relative humidity. Separating pre post trials were five acclimation sessions. Although no significant...

Measuring exercise intensity for safety and to inform prescription in acute burn survivors, is challenging. This study aimed assess the validity of adult patient end-of-workout rating session perceived exertion (sRPE); calculated training load (TL) (sRPE × duration) as measures intensity. Secondly, compare clinician perception effort during physiotherapist-led sessions. Repeated RPE data were collected every 5-min two resistance sessions completed by 25 burns patients. Physiological (heart...

This study aimed to compare the simultaneous use of internal and external precooling methods with singular their effect on repeated sprint cycling in hot/humid conditions. Twelve male team sport players completed four experimental conditions, initially involving a 30-min period consisting either cooling jacket (J); ingestion an ice slushy slushy; combination (J + slushy); or control (CONT). was followed by 70 min repeat (in~35°C, 60% relative humidity [RH]), 2 × halves, separated 10-min...

Abstract Context: Cooling jackets are a common method for removing stored heat accumulated during exercise. To date, the efficiency and practicality of different types cooling have received minimal investigation. Objective: examine whether jacket containing phase-change material (PC17) results in more rapid postexercise than gel no-jacket (control) condition. Design: Randomized, counterbalanced design with 3 experimental conditions. Setting: Participants exercised at 75% V˙o2max workload hot...

Abstract This study compared the effects of a hand cooling glove (∼16°C water temperature; subatmospheric pressure −40 mmHg) and jacket (CJ) on post‐exercise rates (gastrointestinal core temperature, Tc; skin Tsk) cognitive performance (the Stroop Colour–Word test). Twelve male athletes performed four trials (within subjects, counterbalanced design) involving cycling at workload equivalent to 75% ⩒O 2 max in heat (35.7 ± 0.2°C, 49.2 2.6% RH) until Tc 39°C or exhaustion occurred. A 30‐min...

To investigate the influence of shorter, more frequent rest breaks with per-cooling as an alternative heat-acclimation session on physiological, perceptual, and self-paced maximal cycling performance, compared continuous heat exposure.

This study compared traditional rugby union (RU) games to a modified small-sided game (SSG) aimed at improving opportunity for physical activity and enjoyment in children. Twenty-six school players (aged 10 y) played RU matches. Five on full-sized field with 10–12 per team five SSG seven team. Movement patterns, enjoyment, involvements (e.g., possessions, passes, tackles, rucks tries), heart rate (HR) were recorded. Session rating of perceived exertion (sRPE) was measured the end each used...

Purpose: Precooling (PreC) may only benefit performance when thermal strain experienced by an individual is sufficiently high. We explored the effect of mixed-method PreC on 20-km cycling time-trial (CTT) under 3 different apparent temperatures (AT). Methods: On separate days, 12 trained or highly male cyclists/triathletes completed six CTTs in ATs: hot-dry (35 °C AT), moderately hot-humid (40 and (46 AT). All trials were preceded 30 minutes no (control [CON]). Results: Faster 2.5-km-split...

High performance sport consists of stressor events which can disrupt an athletes' functioning and negatively influence performance. The way in one reflects upon develops insights regarding how they coped is essential to overcoming similar experiences the future. We conducted a pilot randomised controlled trial with qualitative analysis explore coping among 48 highly trained/national level swimmers lead up major swimming competitions, who reflected on from self-distanced or self-immersed...

This study aimed to determine if children playing field hockey small-sided games (SSG) have different levels of physiological, performance and perceptual responses, compared traditional hockey. Fifteen school players (10–12 y) played eight matches over four months. Traditional (n = 4) were on a full-sized pitch with 11 per team, SSG as two-separate 8), 7 team half-field pitch. Heart rate, movement data match involvement collected during the game. Participants asked their session rating...

(1) Background: Stimulating oropharyngeal transient receptor potential (TRP) channels inhibits muscle cramping by triggering a supraspinal reflex to reduce α-motor neuron hyperexcitability. This study investigated whether longer stimulation of TRP via mouth rinsing with PJ is more effective than drinking at inhibiting an electrically induced cramp (EIMC); (2) Methods: Tibial nerve in 11 cramp-prone adults were percutaneously stimulated elicit EIMC flexor hallucis brevis three...

This study investigated whether the longer stimulation of TRP via mouth rinsing with PJ is more effective than drinking at inhibiting an electrically induced cramp (EIMC). Both conditions were compared control (water). (2) Methods: The tibial nerves in 11 cramp-prone adults percutaneously stimulated...
