Can physical activity maintain normal grades of body mass index and body fat percentage?
Abstract
Background/Aims : A cross-sectional study was undertaken on 767 urban male volunteers performing physical activity and 469 age and socioeconomic status matched controls not doing any physical activity from the city limits of North India. Materials and Methods : Height and weight were recorded for each participant to determine their Body Mass Index (BMI). Body fat percentage and weight was measured using a body fat monitor. Results : Fifty three percent of the physical activity performers showed normal BMI compared to 49% nonphysical activity performers. Overweight was observed in 43.3% physical activity performers compared to 44.7% nonphysical activity performers. Fifty two percent of physical activity performers had normal body fat percent compared to 48.5% nonphysical activity performers. Low body fat percent was observed in 23.4% physical activity performers compared to 2.7% nonphysical activity performers. High body fat percent was observed in 48.7% nonphysical activity performers compared to 45.8% physical activity performers. Conclusions: Overall, the study suggested that physical activity alone cannot maintain BMI and body fat percent, but it can reduce the risk of overweight and high body fat percent in the population.
