Ten male physical education major students performed treadmill jogging at a mph to study the cardiorespiratory responses to exercise with arm-help(AW) or with leg-held weights(L.W). Eleven load conditions(no added load, loads of 1%, 2%, 3%, 4% and 5% body weights added to either the wrists or ankles) were examined. The results demonstrated that HR, SBP, V˙E, V˙O2, an V˙CO2 increased significantly(p<0.05) as load was increased on both the wrists and ankles. Especially HR, V˙E, V˙O2, and V˙CO2 increased significantly (p<0.05) after the 1% additional external weights(average weights : 0.65㎏) were added to the wrists. In case of the same load(0.65㎏) was added to the ankle HR, V˙E, and V˙O2 increased significantly (p<0.05). SBP increased after 3% additional external weights (average weights : 1.95㎏) were added to the ankles. V˙CO2 increased significantly (p<0.05) after 4% additional external weights(average weights : 2.60㎏) were added to the ankles. HR and SBP for LW were greater than far AW. V˙O2 and V˙CO2 for AW were greater than for LW. DBP and RER did not changed significantly according to the load conditions. These data suggest that 1% wrists or ankles weights can increase the cardiorespiratory benifits of training and may be useful in exercise priscription for the individuals who want to jog.
