This study was conducted to investigate the effects of stride walking on cardiovascular and electromyographical responses on a treadmill in healthy young female (mean age of 23.0 yrs, height of 156.2 cm and weight of 50.6 kg). The subjects performed initial 6 minutes walking based on a heart rate of anaerobic threshold minus 10 beats per minute under two conditions of treadmill walking, on increased velocity with horizontal inclination (A) and on a constant velocity (2.0 mph) with increased grade (B). Consequently, the subjects performed stride walking which was made by 10% reduction of steps under each condition. The results were as follows: 1) Under A condition, the values of leg fatigue by Borg’s 20 numeric scale in stride walking was significantly higher than in non-stride walking, while no difference under B condition. 2) Under A condition, the mean values in oxygen uptake and heart rate during stride walking were significantly higher than during non-stride walking, while no difference under B condition. 3) Under A condition, total amount of integrated electromyogram in gastrocnemius, vastus medialis and tibialis anterior were higher during stride walking than during non-stride walking. Under B condition, gastrocnemius and gluteus maximus showed higher values during stride walking than in non-stride walking. These findings suggest that stride walking manipulated on a high velocity tends to alter cardiovascular and electromyographical parameters than on a lower velocity with higher inclination on treadmill walking in healthy young adults.
