BACKGROUND: Insufficient physical activity and prolonged sedentary behavior among college students are associated with reduced lower-limb muscle strength, impaired dynamic balance, and increased susceptibility to sports-related knee injury. Female college students may be especially vulnerable because of sex-specific neuromuscular and biomechanical characteristics. Tai Chi Chuan may improve proprioceptive control and coordinated knee muscle activation, whereas unstable resistance training may rapidly enhance strength and neuromuscular stabilization. Whether a combined programme can produce complementary central-peripheral benefits remains to be verified in a rigorously designed randomized trial.
METHODS: This protocol describes a single-center, parallel-group, randomized controlled trial. Fifty-seven healthy female college students aged 18-22 years will be recruited from Fenyang College, Shanxi Medical University, and randomly allocated in a 1:1:1 ratio to a Tai Chi Chuan group (TCC), unstable resistance training group (URT), or Tai Chi Chuan combined with unstable resistance training group (T + URT). All interventions will last 8 weeks, with three 60-min sessions per week. The primary outcomes will be dominant-leg knee extensor peak torque, knee flexor peak torque, and hamstring-to-quadriceps ratio measured using an isokinetic strength testing system at 60 degrees/s. Secondary outcomes will include overall stability index, anteroposterior stability index, and mediolateral stability index under eyes-open and eyes-closed conditions measured with the Biodex Balance System. Assessments will be conducted at baseline and after the 8-week intervention. Intention-to-treat and per-protocol analyses will be used. Missing data will be handled using multiple imputation where appropriate.
DISCUSSION: This trial is designed to determine whether Tai Chi Chuan combined with unstable resistance training provides superior improvements in knee muscle function and dynamic balance compared with either intervention alone.
