The effects of weekly motivational phone calls on the amount of leisure sports activities and changes in physical fitness

Abstract

Purpose: The purpose of this study is to investigate whether motivational weekly phone calls are able to promote overall and/or leisure physical activity levels and fitness in an urban population of Romania. Material: Sixty-five adult subjects (30 males and 35 females) were randomly selected and followed over the 8-month study period. Total physical activity and changes in body mass and body mass index (kg/m2) were recorded on a monthly basis. Fitness level was assessed by the participants themselves using three standardized motor tests: push-up test, 1-minute sit-up test and 3-minute step test. Results: The intervention resulted in an increase of physical activity level by approximately 70% in males and females aged 25-39 years. In those aged 40-49 years physical activity levels were enhanced by 77% in males and 18% in females. These changes were associated with improvements (25-31%; p < 0.01) in fitness levels. Changes in physical activity over the 8-month intervention period were negatively correlated with body mass index (r = - 0.721, p < 0.01). Conclusions: This study demonstrates that motivation by regular phone calls was highly effective in increasing leisure sports activities and improving fitness levels in young and middle-aged adults of both sexes.
