Abstract

Various types of physical activity, including tai chi exercises, have become part of physical rehabilitation of young athletes after knee joint injury. However, many physiological mechanisms of the restorative effect of traditional systems still need to be clarified. We recruited 38 girls aged 10–16 years (mean age 12.5 years, interquartile range [10.8; 13.2] years) involved in different types of physical activity (rhythmic gymnastics and choreography) needing to recover their knee joint function after overuse injury. The subjects were divided into two groups: the main group (physical rehabilitation using a specially developed set of tai chi movements) and the control group (standard course of physical rehabilitation taking place in a physical therapy room). After 2 weeks of rehabilitation, the participants underwent isokinetic testing of the knee joint using the Biodex System 4 Pro (USA). The test results obtained by cluster analysis were typified into three characteristic patterns (χ2 test, p = 0.004): 1) insufficiency of strength parameters (peak torque (PT), peak torque to body mass (PT/BM)) at high speed and insufficiency of functional parameters (PT angle, deceleration time) at high speed; 2) insufficiency of functional parameters (time to PT, deceleration time); 3) insufficiency of strength parameters (PT, PT/BM). It was shown that while the classical means of physical rehabilitation are good for restoring the dynamic muscle parameters (PT), tai chi exercises optimally restore the functional parameters of muscle activation (TP angle and deceleration time).
