Is physical activity intensity an important factor for balance skills in sedentary individuals? A pilot study

Aim: While regular sports and exercise are known to improve balance and postural control, it remains unclear whether daily routine physical activity has similar effects, particularly in sedentary individuals. This study aimed to examine whether the intensity of daily physical activity affects functional balance abilities in sedentary adults. Methods: This prospective, cross-sectional study included 34 healthy sedentary individuals aged 19–50 years who did not engage in regular exercise. The Physical Activity Scale-2 (PAS-2) was used to determine participants’ average daily physical activity levels in MET-minutes/day. Height, weight, and body mass index (BMI) were recorded. Balance was evaluated using the Functional Reach Test (FRT), Romberg Test (on firm and foam surfaces), One Leg Standing Test (OLST) with eyes open and closed, and the Timed Up and Go Test (TUG). Results: Among the participants, 28 (82.3%) were female and 6 (17.7%) were male, with a mean age of 22.00±6.75 years. The average physical activity level was 2238.48 MET-min/day. No significant correlation was found between physical activity level and any of the balance test results or anthropometric variables (p>0.05). Conclusion: In sedentary individuals, the intensity of daily routine physical activity does not appear to significantly influence functional balance skills. These findings highlight that general daily activity alone may not be sufficient to improve balance, emphasizing the need for structured and regular exercise interventions.
