Postural Stability in Individuals with Different Levels of Physical Activity: A Preliminary Study

Abstract

Purpose: This study aimed to investigate the differences in posture, static balance, and dynamic balance among young adults with varying levels of physical activity. The research explored the potential impact of physical activity on postural stability, focusing on posture and balance in individuals with different activity levels. Methods: A cross-sectional study was conducted with 23 healthy young adults aged 18-29 years. Physical activity levels were assessed using the International Physical Activity Questionnaire - Short Form (IPAQ). Posture was evaluated through photographic method, and static balance were measured using the FreeMed baropodometric platform. Participants were categorized into inactive, minimally active, and active groups based on their MET-min/week scores. Balance outcomes were measured through Delta X, Delta Y, and AVsurface, including monopodal and bipodal stances, with eyes open and closed. Results: No significant differences in forward head posture were found across groups (p = 0.630). However, balance parameters such as Delta X and Delta Y in closed-eye monopodal stances demonstrated significant differences. The active group showed superior stability in these balance tests in closed-eye monopodal stances (p < 0.05). Discussion: Regular physical activity was associated with better balance, particularly in dynamic tasks, as evidenced by improved stability in closed-eye monopodal balance tests. While no differences were observed in posture, the results suggest that physical activity enhances proprioceptive control and neuromuscular coordination, which contribute to improved postural stability. These findings underscore the importance of physical activity in enhancing balance and stability, especially under challenging conditions. Further research is needed to explore the long-term effects of physical activity on postural control.
