The Combination Of Cooling Techniques In A Tropical Environment Improves Precision Performance In Young International Fencers, Aurélie Collado, Nicolas Robin, Stéphane Sinnapah, Elisabeth Rosnet, Olivier Hue, Guillaume R. Coudevylle Jun 2023

The Combination Of Cooling Techniques In A Tropical Environment Improves Precision Performance In Young International Fencers, Aurélie Collado, Nicolas Robin, Stéphane Sinnapah, Elisabeth Rosnet, Olivier Hue, Guillaume R. Coudevylle

Journal of Human Performance in Extreme Environments

The performance of intense exercise in a tropical climate is associated with limited exercise capacity due to thermal strain. This limitation is exacerbated in sports requiring full protective equipment. Research evidence suggests disturbances in cognitive function due to thermal discomfort and/or protective equipment (e.g., helmets), and thus sports that require skills in decision-making, fast reaction times, precision, and/or inhibition can be greatly affected. The objective of this study was to investigate the effects of countermeasures on the psychological and physiological responses in young international fencers wearing full protective equipment during an ecological fencing task. Nine young international fencers performed an …

Background: It is unclear whether energy intake can impact the incidence of upper respiratory symptoms (URS). The purpose of this study was to examine if there are differences in energy intake between symptomatic (SYM) and asymptomatic (ASYM) groups of URS in Ironman-triathletes. Methods: Thirty-three subjects competing in the Lake Placid Ironman-triathlon (mean±SD; age,37±8y; height,178±8cm; mass,76.3±10.4kg; body fat,10.8±3.8%) were randomized into either the control (CON) or intervention (INT). INT consumed 4-commercial recovery drinks, two immediately post-race and two 3-hours post-race. Calorie and macronutrient intake were recorded pre-, during, and post-race. Subjects completed the Wisconsin URS Survey to assess URS over the …

Safety–Performance Management In Extreme Sports? A Situated Analysis In Spearfishing Activity, Aude Villemain, Willy Buchmann Apr 2019

Safety–Performance Management In Extreme Sports? A Situated Analysis In Spearfishing Activity, Aude Villemain, Willy Buchmann

Journal of Human Performance in Extreme Environments

The aim of this research is to understand safety–performance articulation in spearfishing through the study of the global, specific, and temporal organization of an elite free diver’s activity. Three kinds of data were collected: diary reports, ten elicitation interviews on spearfishing, and two self-confrontation interviews on successful and failed apneas. The results indicated (1) the spearfisher’s global organization during the spearfishing set, (2) the alternation of intentions during apnea and periods of stabilization, (3) harmony with the environment, and (4) the strategy of keeping pace with the fish. The article will discuss the specific competence development needed to manage the …

Use Of Psychological Skills By Risk Sport Athletes, Patrick R. Young, Erin L. Knight Nov 2014

Use Of Psychological Skills By Risk Sport Athletes, Patrick R. Young, Erin L. Knight

Journal of Human Performance in Extreme Environments

Psychological skills can help athletes maximize their physical skills (Smith, Schutz, Smoll, & Ptacek, 1995) and overcome sport-related adversity. These skills may be especially beneficial to athletes performing within natural and unstable risk sport environments. The current study assessed psychological skills among risk sport athletes (N = 232) and the impact of experience on the use of such skills. Risk sport athletes of varying degrees of experience completed a modified version of the Athletic Coping Skills Inventory (ACSI; Smith et al., 1995). Risk sport athletes exceeded the midpoint on all of the ACSI subscales, indicating psychological skills usage. Experienced …

The Relationship Between Body Composition And Thermal Responses To Hot And Cold Water Immersion, Jessica M. Stephens, Christos Argus, Matthew W. Driller Apr 2014

The Relationship Between Body Composition And Thermal Responses To Hot And Cold Water Immersion, Jessica M. Stephens, Christos Argus, Matthew W. Driller

Journal of Human Performance in Extreme Environments

The current study aimed to examine the influence of body fat percentage on thermal responses to water immersion at the two temperature extremes used in athletic recovery, by comparing the thermal responses of low- and high-fat individuals to immersion in hot water (HWI) or cold water (CWI). Thirty-nine subjects completed a body composition assessment (to determine low-fat and high-fat groups), and 15 minutes of either CWI (n = 20) or HWI (n = 19), followed by 30 minutes of passive rest. Core temperature (Tc), skin temperature (Tsk), and thermal sensation (TSS) were recorded at various time points during …
