Comparison of Limb and Joint Strengths between Tai Chi Chuan Players and Non-Tai Chi Chuan Groups by Using a Force Sensor

Background: Tai Chi Chuan (TCC) is popular in exercise, but little research has been done on limb and joint strength after the exercise. This study aimed to investigate whether TCC players have different strengths upper lower limbs from non-Tai (NTCC). Methods: Twenty who at least one year of experience playing were compared with a group 25 NTCC participants. A force sensor was used measure forces limbs. Maximum produced by measured during standing position straight legs or seated position. The maximum elbow shoulder levels. Results: knee extensors significantly higher (7.4%) than group; however, flexors group. heel-force hip extension (9.3%) TCC; toe-force plantar flexion There no significant differences between two groups hand-forces Conclusions: routine movements strengthen muscles related extension, which are mainly bending performance For healthy people 42 78 years old, benefits enhancement for not flexion, ankle extension. difference joints. As whole, effect exercise joints compromised. In future, larger sample size this highly recommended.
