Brief Summary

In this study, which will investigate the effects of 12-week strength training with 8-week detraining on movement patterns, lower limb strength, and dance performance among Chinese college dancesport athletes, functional movement patterns, muscle architecture, lower limb strength and power, and dance performance will be measured. In dance activity, implementing appropriate strength conditioning programs can effectively enhance dancers' strength levels and improve performance while preserving the integrity of technical and aesthetic elements. The study is a randomized controlled trial. Dancesport major students will be assessed according to the screening conditions, and 30 participants will be recruited. Participants will be randomly assigned to an intervention group or a control group. The intervention group will undergo training three times per week, 60 minutes per session, for 12 weeks. All participants will undergo measurements at four time points: baseline, after six weeks, after twelve weeks, and after eight weeks of detraining.

Outcome Measures

Primary Outcomes (5)

• Functional Movement Screen (FMS) Total Score

  Assesses fundamental movement quality using a standardized 7-action screening tool. The Functional Movement Screen (FMS) is a comprehensive tool designed to evaluate an individual's fundamental movement patterns. The FMS has been shown to correlate significantly with athletic performance, supporting its validity as a functional assessment tool.

  Baseline, 6 weeks, 12 weeks, and 8 weeks after detraining (up to 20 weeks per participant)

• Y-Balance Test

  The Y Balance Test is a validated functional assessment tool designed to evaluate dynamic balance, neuromuscular control, and injury risk in both upper and lower extremities by quantifying dynamic stability and identifying functional asymmetries predictive of lower extremity injury risk.

  Baseline, 6 weeks, 12 weeks, and 8 weeks after detraining (up to 20 weeks per participant)

• Isokinetic strength test for the knee and hip

  Isokinetic strength testing provides a dynamic and objective method for evaluating muscle function under constant angular velocity, enabling the quantification of parameters such as peak strength, total work, and muscular endurance.

  Baseline, 6 weeks, 12 weeks, and 8 weeks after detraining (up to 20 weeks per participant)

• Jump test for power

  Jump test by force platforms can provide multi-dimensional key parameters such as strength, power, speed and time by accurately measuring the ground reaction force (GRF).

  Baseline, 6 weeks, 12 weeks, and 8 weeks after detraining (up to 20 weeks per participant)

• Dance performance for the qualitative aspects

  The dance performance assessment was divided into two parts. The first part evaluated dance performance using the Performance Competence Evaluation Scale (PCEM); the intra- and inter-rater reliability coefficients were 0.95 and 0.94, respectively, indicating strong validity and reliability of the measure. The second part assessed competition performance based on the World Dancesport Federation (WDSF) rules, which are widely used in major dancesport competitions worldwide.

  Baseline, 6 weeks, 12 weeks, and 8 weeks after detraining (up to 20 weeks per participant)

Interventions

strength training BEHAVIORAL

A 12-week strength training program designed for college dancesport athletes. Training is performed three times per week, 60 minutes per session, in addition to participants' regular dancesport training. Exercises include multi-joint resistance movements (e.g., squats, lunges, deadlifts, jumps) following NSCA guidelines with progressive overload based on 1RM. After the 12-week intervention, participants continue with an 8-week detraining phase without supplemental strength sessions and dance training.
