- Abstract
The study compares the speed of step initiation in physically active and sedentary individuals in the ages of from 20 - 25 and 60 - 65 years of age. Speed of step initiation was measured using FiTRO Dyne Premium, the system based on precise analogue velocity sensor with sampling rate of 100 Hz. Maximal step velocity was analysed as only this parameter showed excellent reliability, with low SEM (3.1 %) and high ICC (0.94). This parameter showed also sufficient sensitivity to discriminate between individuals of different age and level of physical fitness. As expected, maximal step velocity was significantly higher in physically active individuals than in sedentary young ones.(10.4 %, p = 0.031). Its values were also significantly higher in physically active than sedentary older subjects (12.2 %, p = 0.026). However, maximal step velocity did not differ significantly (p = 0.191) between sedentary young and physically active older subjects. These findings indicate that physical fitness rather than the age plays a role in speed of step initiation. Such a test may be applied in evaluation of actual level of physical performance in various populations and efficiency of exercise or rehabilitation program.
