Previous studies have explored the effect of differing heat and relative humidity (RH) environments on performance multiple anaerobic high-intensity interval training (HIIT). Still, its impact physiological responses following aerobic HIIT has not been well studied. This study examined effects RH in college football players HIIT. Twelve completed under four different environmental conditions: (1) 25 °C/20% (Control group); (2) 35 (H20 (3) °C/40% (H40 (4) °C/80% (H80 group).

This thesis details the meta-analytical and experimental work conducted to investigate effects of dietary supplements, specifically taurine, on physiological thermoregulatory responses in humans during heat exposure. Meta-analysis determined that ergogenic many supplements endurance exercise performance appear affected by heat. Supplements established be efficacious thermoneutral conditions, such as caffeine creatine provided no benefit, while amino acids (e.g. taurine) demonstrated greatest ergogenicity. Of meta-analysed for their effects, several acids, anti-oxidants anti-inflammatories, those affecting fluid balance, offered benefits Conversely, enhancing nitric oxide bioavailability had effect thermal induced a thermogenic when ingested Overall, taurine responses, was, therefore, selected focus subsequent empirical data chapters. Within studies thesis, supplementation augmented sweating fixed metabolic production hot including increased whole-body sweat loss, local rate gland activation, alongside cutaneous vasodilation. Greater translated heightened evaporative dissipation reduced storage, modelled partitional calorimetry. Improved tolerance was also observed, through delayed transition uncompensable stress. Drivers response measurement techniques used assess these were sufficiently reliable control detect likely changes, respectively. indicates findings regarding taurine’s are genuine unaffected influencing factors. Taurine may exert its vaso-active osmoregulatory roles, though this requires further investigation. Nevertheless, offer potential strategy support thermoregulation environmental conditions permit dry transfer.

Background: Caffeine is widely recognized as an ergogenic aid to enhance athletic performance, yet its effects in hot environments remain relatively underexplored. Aims: To provide a comprehensive overview of the research landscape and identify themes this field. Methods: We systematically searched Web Science (WoS) SCOPUS databases using keywords related caffeine (e.g., caffe*), heat, hot, or therm*), performance cardio, endurance, strength). The Bibliometrix package R was used for bibliometric analysis result visualization, while narrative review subsequently performed themes. Results: found that studies examining impact on exercise conditions are sparse have progressed slowly recent years. Research domain has predominantly been concentrated within academic network led by Professor Lawrence Armstrong. Recent contributions sporadically made emerging scholars, with collaborations largely confined few groups countries. Key identified include thermoregulation, fluid balance, physiological responses, immune synergistic other compounds, influence individual differences. Of these, first three themes—exercise balance—have received most attention. Conclusions: Caffeine’s not thoroughly studied. existing varied, conclusions show considerable inconsistencies. Our study highlights need further into dosage, administration methods, population-specific variables. also call increased collaboration among advance scientific understanding address gaps
