Clinical Trial Summary
Three male and three female semi-professional athletes, ranging in age from 22 to 27,
participated in a study that was done at Lund University in Sweden to examine their
physiological responses. The temperature and relative humidity were adjusted at 40 degrees
Celsius for hot, dry conditions and 31 degrees Celsius for hot, wet conditions, respectively.
The participants were instructed to engage in physical activity on a treadmill within the
chamber for 70 minutes, or until participants were able to continue their exercise without
difficulty within the allotted period. Participants were instructed to walk (5 kph) and run
(8 kph). Participants pulse rate, breathing rate, oxygen consumption, and subjective
reactions were all recorded.
On the basis of the Wet Bulb Globe Temperature (WBGT), a heat stress index, the American
College of Sports Medicine has made certain suggestions. The technique used to determine the
temperature on a Celsius scale took into account the influences of relative humidity, air
temperature, wind, and direct sunlight radiation. The American College of Sports Medicine
advises delaying athletic competition when the WBGT is above 28 degrees. In the climate
control chamber, the trials were carried out in high-risk circumstances (28 degrees Celsius
WBGT). According to the study's findings, exercise is influenced by weather, and as air
temperature rises, so do the intensity of exertion and thermal feeling.
Description:
Methodology Experimental research design Study Duration 6 months Study Centres Thermal
Environment Laboratory, Department of Design Sciences, Faculty of Engineering (LTH), Lund
University Main Objectives Objective 1: To examine the physiological responses (skin
temperature, core body temperature, body temperature, heart rate, and oxygen uptake) of
semi-professional athletes during physical activity in different climatic conditions (hot wet
and hot dry) Objective 2: To compare the effects of physical activity intensity (5 km/hr and
8 km/hr) on the physiological responses of semi-professional athletes under varying climatic
conditions.
Objective 3: To investigate the influence of gender on the physiological responses of
semi-professional athletes during physical activity in different climatic conditions.
Objective 4: To assess the suitability of the Physiological Heat Strain (PHS) and Wet Bulb
Globe Temperature (WBGT) index for evaluating heat stress in sports settings based on the
findings from semi-professional athletes.
No. of Participants Six semiprofessional athletes including three males and three females
with a mean age of (24.7 ± 2.1 years) and a body surface area mean of (1.8 ± 0.2 m2)
participated in this study.
Main Eligibility Criteria Key factors to consider when defining semiprofessionals include
participation in regional competition level, receiving monetary compensation for their sports
participation, participating in sports activity in the last six years, and skill level. These
athletes typically demonstrate a higher level of skill and performance than recreational or
amateur participants.
