Application of Analysis of Variance in Evaluating Skin Temperature Changes in the Throwing Hand of Female Handball Players During Training Using Thermal Imaging

This study investigates the temperature changes in the throwing hand of female handball players during training sessions using thermal imaging technology. By applying Analysis of Variance (ANOVA), the study evaluates the significance of skin temperature variations across different hand surface areas over time. The aim is to identify any statistically significant differences in temperature changes due to the physical demands of handball training. The findings provide insights into how thermal stress affects specific areas of the throwing hand, potentially informing better training practices and injury prevention strategies.

I. Introduction

Handball training imposes considerable physical demands on certain muscle groups and body parts, especially the throwing hand. Tracking changes in skin temperature provides valuable insights into physiological responses and potential injury risks [1]–[4]. Thermal imaging, along with monitoring sensors and thermal scanners, offers an effective, non-invasive approach to assess these temperature fluctuations, which can indicate underlying muscular or circulatory stress [5]–[6]. This study examines the throwing hand of female handball players, exploring skin temperature changes during training sessions. Analysis of Variance (ANOVA) is employed to evaluate the significance of temperature differences across various regions of the hand [7], [8].
