Dry-land Strength and Conditioning for Competitive Youth Swimmers

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.

Treatment and study plan

Dry-land strength and conditioning programme

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.

Active control condition

Behavioral

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

Primary outcomes

  1. Swim start performance

    Time frame: From enrolment to 3 weeks after the end of the intervention

    Time to 7.5m from a race start

  2. Swim turn performance

    Time frame: From enrolment to 3 weeks after the end of the intervention

    5m turn around time during maximal effort front-crawl swimming with tumble-turn

Secondary outcomes

  1. Swim race performance

    Time frame: From enrolment to 3 weeks after the end of the intervention

    Time to complete a maximal 50m front-crawl race

  2. Countermovement jump performance

    Time frame: From enrolment to 3 weeks after the end of the intervention

    Maximum height achieved on the countermovement jump test

  3. Lower-body strength

    Time frame: From enrolment to 3 weeks after the end of the intervention

    Peak force achieved on an isometric mid-thigh pull test

  4. Shoulder strength

    Time frame: From enrolment to 3 weeks after the end of the intervention

    Peak force achieved in the Athletic Shoulder Test with the arm tested in the 90- and 135-degree positions
