The bicycle ergometer is the most frequently used equipment for loading tests for the purpose of functional diagnosis and for the purpose of locomotor rehabilitation. The energy required to meet this locomotor activity is within a wide range of load intensities which depends linearily on the intensity of pedalling. The steepness of this linear relationship which characterizes the degree of adaptation of the organism to this type of locomotor activity is the smaller the more the investigated subjects are adapted to the load. In general it depends on the degree of training, age, sex, strength, pedalling frequency, on the load protocol and on the biomechanical conditions during pedalling (e.g. the height of the saddle). Based on our measurements in a group of untrained women of different age and in trained women of different age it can be demonstrated that all individual relations between energy characterized by means of VO2 and the intensity of the load - P is within the zone where the upper borderline is formed by the equation VO2(ml) = 11.00.P (W) + 403 and the lower borderline by VO2(ml) = 9.90.P (W) + 252. The basic relationship, independent on the degree of training, age and strength, valid in the zone of pedalling frequencies of 60-80 rot. min-1 and in the zone of load intensities of 75-325 W has the shape of VO2(ml) = 10.60.P(W) + 269. The maximum error of assessment of VO2 by means of the load intensity is 9% or less.
自行车测力计是功能诊断和运动康复中最常用于负荷测试的设备。满足这种运动活动所需的能量处于广泛的负荷强度范围内，该范围线性依赖于蹬踏强度。这种线性关系的斜率表征了机体对这种运动活动的适应程度，被调查对象对负荷的适应程度越高，该斜率越小。一般来说，它取决于训练程度、年龄、性别、力量、蹬踏频率、负荷方案以及蹬踏过程中的生物力学条件（如鞍座高度）。基于我们对一组不同年龄的未受过训练的女性和不同年龄的受过训练的女性的测量结果，可以证明，以VO₂表征的能量与负荷强度 - P之间的所有个体关系都在由方程VO₂(ml) = 11.00.P (W) + 403形成上边界、VO₂(ml) = 9.90.P (W) + 252形成下边界的区域内。在蹬踏频率为60 - 80转/分钟且负荷强度为75 - 325瓦的区域内有效的、与训练程度、年龄和力量无关的基本关系具有VO₂(ml) = 10.60.P(W) + 269的形式。通过负荷强度评估VO₂的最大误差为9%或更小。
