- Abstract
There is a debate among researchers regarding the impact of environmental factors, such as varying temperatures, on bodily functions, particularly the respiratory system of athletes. Hence, investigating the influence of moderate to cold weather on athletes during exercise is essential for comprehending this relationship and determining optimal strategies for public health maintenance, fitness enhancement, and performance improvement under diverse environmental conditions. Consequently, this study aims to ascertain the impact of the surrounding environment on individuals, the extent to which their physiological systems are affected, and the resultant manifestations, especially during physical exertion. The primary aim of the present study was to assess the differences in respiratory system variables (respiratory rate (RR), tidal volume (TV), pulmonary ventilation (V̇ E)), as well as other parameters (heart rate (HR), completion time (Ct)), at rest and post-cardiorespiratory exercise test (CPET) between moderate heat (24°C ± 1) and cold conditions (15°C ± 1). The researcher hypothesized that there would be no significant disparities in respiratory system variables (RR, TV, V̇ E), HR, and Ct between the moderate and cold conditions, both at rest and after CPET. A descriptive approach was chosen for its suitability to the nature of the study. The research sample comprised eight randomly selected individuals aged between 22 and 24 years who engaged in physical activity. The experimental sessions were conducted in two different thermal conditions: moderate temperature (24°C ± 1) with 30-40% humidity, and cold temperature (15°C ± 1) with 30-40% humidity. Data processing involved the use of statistical and computational methods such as arithmetic mean, standard deviation, coefficient of variation, body mass index, body surface area, and t-tests for two related samples. The findings of the study revealed the following: - Cold environmental conditions led to a significant increase in comfort in the variables TV, V̇ E, and HR at the conclusion of physical exertion, as well as an increase in RR, compared to temperate conditions. - Cold environmental conditions did not result in a significant increase in comfort in RR, TV, V̇ E, and HR at the end of physical exertion in comparison to temperate conditions. - The cold environmental condition during physical exertion did not exhibit a clear negative or positive impact on Ct in terms of the duration of the end of exertion compared to the moderate.
