Abstract
The purpose of this study was to measure heart rate(HR), energy expenditure(EE), body fat mass(BF), muscle mass(MM) among walking types on treadmill for investigating the difference of walking with or without hand weights. Seven healthy men (age: 23.5±0.79) volunteered for this experiment. Each of them performed 4-types of walking(dumbbell, nordic, power, and general) at speed of 3~5km/h(warm up), 6km/h(slow), 7km/h(fast), and 5~3km/h(cool down) for 40 minutes on a treadmill. HR and EE data were measured by heart checker(POLOR 810i) at slow and fast walking and FM and MM were measured by body fat impedance system(INBODY 3.0) at rest and after walking. As a result, at slow walking, walking with 3-pound hand weight way showed higher score(HR:127.8±8.27bpm, EE:85.4±14.51 kcal/min) compared to general walking way(104±8.2bpm, and 70.4±10.99kcal/min). Nordic walking way(121.4±11.74bpm, 77.0±16.83kcal/min) was second, power walking way(118.5±9.98bpm, 68.7±20.62kcal/min respectively) was next. At fast walking, same trend was shown. Especially, at the end of 40min aerobic walking exercise, walking with 3-pound hand weight way showed higher score compared to general walking way in THR(t=2.792, p=0.016, p<.05). The both highest FM decreasing and MM increasing was shown in dumbbell walking type(FM:-1.03kg, MM:0.66kg) followed by nordic, power, general walking way. In conclusion, these results can be interpreted that the ways with hand weight(dumbbell, or nordic pole walking) during walking exercise can be more effective than general walking.
