About

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.

Full 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.
