Abstract:
Introduction and Aim:
During exercise, different physiological systems work together to help the body adapt. An innovative approach such as palmar cooling — the application of cold packs to the palms of the hands — explores the potential regulation of body temperature during exercise. This study examines the effects of palmar cooling on changes in heart rate, perceived exertion, body temperature, and workload during aerobic activity. The aim is to determine whether palmar cooling can reduce the increase in body temperature and perceived exertion, thus contributing to regular exercise, optimizing physical activity, and promoting a healthy lifestyle in people whose exercise is impaired by exertion.
Methods:
The study involved 24 students aged between 20 and 23 years, all in average physical condition and without acute or chronic illnesses at the time of the study (i.e., no doctor-ordered sports bans). Cold-sensitive individuals and persons with acute or chronic health problems or musculoskeletal injuries were excluded. The Astrand-Rhyming Cycle Ergometer Test, a submaximal cycle ergometer test, was used to analyze the differences in the four parameters between two conditions: with and without palmar cooling. Descriptive statistics, the Wilcoxon test, and the Chi-square test were used for statistical analysis.
Results and Conclusion:
Differences in heart rate, perceived exertion, and workload between the two conditions were not statistically significant. However, the significantly lower body temperature observed in the palmar cooling condition confirms the potentially positive effect of palmar cooling on the consistency of aerobic physical activity.
