The two aims of this study were first to measure short-term muscle power (STMP) by means of a cycling force-velocity test (cycling peak power: CPP) and a vertical jump test (jumping peak performance: JPP) and second, to examine the relationships between physical activity (PA) level, peak oxygen uptake (peak VO2) and STMP in healthy elderly women. Twenty-three independent community-dwelling elderly women (mean age: 64+/-4.4) performed on separate days, a peak oxygen uptake test on cycle ergometer, a cycling force-velocity test and a vertical jump test. A questionnaire (QUANTAP) was used to assess lifespan exercise habits. Four indices expressed in kJ day(-1) kg(-1) were calculated. Two indices represented average past PA level: 1/quantity of habitual physical activity (QHPA), 2/quantity of sports activities (QSA). Two indices represented the actual PA level: 3/actual quantity of habitual physical activity (AQHPA), 4/actual quantity of sports activities (AQSA). CPP (6.3+/-1.2 W kg(-1)) was closely correlated to JPP (14.8+/-3.4 cm) (r=0.80, P<0.001). AQHPA and AQSA were only positively associated with peak VO2 (ml min(-1) kg(-1)) (r=0.49; r=0.50, P<0.05, respectively). Past PA level was not related to fitness measurements. Results show that in this population: (1) jumping peak performance was closely related to CPP measured in the laboratory; (2) the cardio-respiratory fitness was related to the actual habitual physical activity level; (3) only age and anthropometric variables explained the actual performances in multivariate analysis.
本研究的两个目的，一是通过自行车测力-速度测试（自行车峰值功率：CPP）和垂直跳跃测试（跳跃峰值表现：JPP）来测量短期肌肉力量（STMP），二是研究健康老年女性的身体活动（PA）水平、峰值摄氧量（峰值VO₂）与STMP之间的关系。23名独立居住在社区的老年女性（平均年龄：64±4.4岁）在不同日期分别进行了自行车测力计峰值摄氧量测试、自行车测力-速度测试和垂直跳跃测试。使用一份问卷（QUANTAP）来评估终生运动习惯。计算了四个以kJ·day⁻¹·kg⁻¹表示的指标。两个指标代表过去的平均PA水平：1/习惯性身体活动量（QHPA），2/体育活动量（QSA）。两个指标代表实际PA水平：3/习惯性身体活动的实际量（AQHPA），4/体育活动的实际量（AQSA）。CPP（6.3±1.2 W·kg⁻¹）与JPP（14.8±3.4 cm）密切相关（r = 0.80，P < 0.001）。AQHPA和AQSA仅与峰值VO₂（ml·min⁻¹·kg⁻¹）呈正相关（r = 0.49；r = 0.50，P均< 0.05）。过去的PA水平与体能测量结果无关。结果表明，在该人群中：（1）跳跃峰值表现与实验室测量的CPP密切相关；（2）心肺适能与实际习惯性身体活动水平相关；（3）在多变量分析中，只有年龄和人体测量变量能够解释实际表现。
