Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Starts and turns play an important role in swimming performance, with starts accounting for around a quarter of the total time achieved in a 50m freestyle race and have been recommended as a high priority area for improvement by York City Baths Club (YCBC). The relationship between starts and turns and plyometric and general strength training is well documented. However, few studies have explored this relationship in competitive youth swimmers. This non-randomised controlled trial will evaluate the effects of a dry-land strength and conditioning programme, when added to usual swim training, on the physical fitness and start and turn performance of regional- and national-level age-group swimmers. The study intervention will involve two supervised gym sessions per week for 10 weeks. Study outcomes will be assessed before the intervention, at the midpoint and at 1 week and 3 weeks post-intervention. The following testing will occur: Pool-based testing (50m Freestyle; a Time to 7.5m test; Turn time); Gym-based testing (Counter-movement jump; Isometric Mid-Thigh Pull; Athletic Shoulder (ASH)) The dive and turn measures will be assessed via video recordings.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention group

Group Type EXPERIMENTAL

Dry-land strength and conditioning programme

Intervention Type BEHAVIORAL

Participants in the experiment group will be asked to complete two supervised gym sessions per week for 10 weeks. Each session will include a variety of plyometric and strength exercises, selected for their relevance to start and turn performance in swimming.

Control group

Group Type ACTIVE_COMPARATOR

Active control condition

Intervention Type BEHAVIORAL

The control group will complete their usual swimming training which comprises of several pool-based session and one land-based session each week.
