About this study
Official title: The Effects of 12-week Strength and Power Training on Movement Pattern, Physical Fitness and Lower Limb Strength Among Chinese College Sports Dancers
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.
Read the detailed description
All participants are randomly allocated into the intervention group (n = 15) and the control group (n = 15). Allocation is performed by drawing lots. Fitness coaches and medical staff from Hubei Normal University who provide the intervention cannot be blinded to group allocation. The assessment staff remain unaware of the main group allocation. Participants are instructed to refrain from discussing their randomization assignment with the assessment staff or classmates. The study measurements include the functional movement screen, Y-balance test, lower limb muscle architecture, lower limb strength and power, and dance performance tests at baseline, mid-intervention, post-intervention, and after 8 weeks of detraining. During the intervention, training sessions are monitored using the rating of perceived exertion (RPE) and heart rate. Each complete measurement requires approximately two days. Written informed consent is obtained from all participants before the pre-intervention assessment. Day 1: muscle architecture, jump tests using a force platform, and dance performance test; Day 2: isokinetic strength tests, functional movement screen and Y-balance test. Before the first week of intervention, the research team demonstrates and teaches the participants the correct movement techniques, warm-up and stretching procedures, and baseline measurement procedures. Measurements are repeated after 6 and 12 weeks of intervention and after 8 weeks of detraining. The intervention group performs lower limb strength training for 12 weeks, three times per week, 60 minutes per session, in addition to dance training. The control group continues with dance training only, without any additional intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
strength trainingBehavioural
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.
| Study group | Role | What they receive |
|---|---|---|
| intervention group | Experimental | strength training and dance traininig Receives: Behavioral: strength training |
| control group | No intervention | dance training |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: 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.
Measured: 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).
Measured: 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.
Measured: Baseline, 6 weeks, 12 weeks, and 8 weeks after detraining (up to 20 weeks per participant)
