영문 초록

Objective: This study is to investigate the impact on energy consumption and exercise intensity during forward and backward walking treadmill for various slope. Method: Each subject completed a treadmill maximal oxygen uptake (VO2max) test and four constant velocity walking trials. These trials differed in walking mode (ie., forward and backward) and elevation (ie., 0°, 5° and 10°). The six walking trials were administered in a counterbalanced order, with each subject randomly assigned to a predetermined sequence. The six walking trials were separated by at least 24 hours and completed within a 3-week period. Results: Percent maximum heart rate (HRmax) and percent maximum oxygen consumption(VO2max) increased incrementally for treadmill grades of 5° to 7.5° to 10° for both FW and BW(p<.01). For each of the 3 treadmill grades, percent HRmax and percent VO2max was 17% to 20% higher for BW than for FW(p<.01). No statistically significant interactions were detected between direction of walking and treadmill grade. Conclusion: Backward walking on a treadmill at 4 km/h and grades of 0°, 5°, and 10° elicits a greater percent HRmax and percent VO2max than does forward walking under the same conditions and, if incorporated into sustained training regimens, would be expected to improve aerobic endurance.
