Physiological and mechanical consequences of running with commercially available hand and/or ankle weights were examined. Five males and three females (age 30 to 56 yr) ran for 30 min on a treadmill (0% grade) at a self-selected pace (8.9 to 13.7 km.h-1), under randomized conditions of: (i) unloaded weights; (ii) hand weights; (iii) ankle weights; and (iv) hand + ankle weights. Respiratory gas exchange determinations, heart rates, and sagittal view film clips were obtained at selected time intervals. Highest energy expenditures and heart values were obtained for the fully loaded condition, with intermediate values measured for independent hand- and ankle-weighted trials. Increased energy expenditure due to loading ranged from 5 to 8%. Lower extremity kinematics were unaffected by loading. Angular velocity and excursion of the arm segments was significantly (P less than 0.05) reduced when hand weights alone were carried. The results indicate that commercial claims of marked increases in energy expenditure during running with hand/ankle weights are exaggerated. It appears that the small actual increases in energy expenditure, the potential for increased impact forces, and the relative discomfort of carrying weights discredit running with hand and/or ankle weights as a desirable exercise alternative.
研究了使用市售的手部和/或踝部负重跑步的生理和力学后果。五名男性和三名女性（年龄30至56岁）在跑步机（坡度0%）上以自定速度（8.9至13.7公里/小时）跑步30分钟，处于以下随机条件下：（i）无负重；（ii）手部负重；（iii）踝部负重；以及（iv）手部+踝部负重。在选定的时间间隔获取呼吸气体交换测定值、心率和矢状面影片剪辑。在负重完全的情况下获得了最高的能量消耗和心率值，在单独进行手部和踝部负重试验时测得的数值处于中间水平。负重导致的能量消耗增加幅度为5%至8%。下肢运动学不受负重影响。单独佩戴手部负重时，手臂节段的角速度和摆动幅度显著（P<0.05）降低。结果表明，关于使用手部/踝部负重跑步期间能量消耗显著增加的商业宣传有所夸大。似乎实际能量消耗的小幅增加、冲击力增加的可能性以及负重带来的相对不适感，都使使用手部和/或踝部负重跑步作为一种理想的运动选择不可信。
