Abstract: (313 Views)
Background: Many human activities in both work and daily life depend on hand function. Exposure to extreme temperatures can impair this function, reducing grip strength and agility, which may lead to adverse effects for health, safety, and occupational performance, as well as an increased risk of accidents. Therefore, the present study aimed to investigate the relationship between skin temperature and hand grip strength.
Methods: Thirty volunteers were randomly selected based on the criteria of having no history of illness, surgery, injury in the hand area, or pain in the upper limb. Hand skin temperature and grip strength were measured before and after hand immersion in hot water (40 °C) and cold water (11 °C) using a laser thermometer and a dynamometer, respectively. The data were analyzed using SPSS software.
Findings: The average grip strength of men and women at normal laboratory temperature was 42.89 kg and 27.44 kg, respectively. After hand immersion in hot water, grip strength reduced to 39.40 kg for men and 26.52 kg for women (P = 0.44). Following hand immersion in cold water, grip strength decreased further to 36.33 kg for men and 23.44 kg for women (P = 0.62). These findings indicate a significant relationship between skin temperature and grip strength, particularly when hands are immersed in cold water (P < 0.05).
Conclusion: Changes in hand skin temperature directly affect the reduction of grip strength. Furthermore, exposure to a cold environment reduces grip strength more significantly than exposure to a warm environment.
