This study was designed to investigate the effect of leg-weight loading on energy expenditure and heart rate response during gradual speed-up treadmill walking exercise. Nine volunteer college students were asked to walk two times at various incremental speeds on treadmill being loaded with 2.3kg weight belt at their ankle and without being loaded. The duration of each stage was 3minutes and every subject was encouraged to keep performing till their exhaustion states. Loading the weight(mean 3.09% of subject`s body weight) at ankle during treadmill walk showed no remarkable change in oxygen consumption, energy expenditure at less than 6km/hr walk speed compared to no loading walk. But, at the 7km/hr walk speed significant increase of oxygen consumption and energy expen- diture were found(p<0.05). Heart rate response was also significantly increased only at more than 7km/hr walk speed(p<0.01). These results represent that the threshold of treadmill walk speed inducing significant increase of oxygen consum- p tion, energy expenditure and cardiovascular response might be 7km/hr in healthy collegeate students when the weight corresponding 3.09% of their body weight would be loaded at their ankle.
