HIIT Versus High-Volume Training in Competitive Para Swimmers
Sponsor: National and Kapodistrian University of Athens
Summary
This study compared the effects of four weeks of reduced-volume high-intensity interval training and higher-volume moderate-intensity swimming training on repeated-sprint ability, physiological responses, and body composition in competitive para swimmers. Twenty-four national-level swimmers representing World Para Swimming sport classes S5-S10 and S14 were randomly allocated to one of the two training interventions by drawing sealed group assignments. Both groups completed two supervised sessions per week for four weeks. Repeated-sprint ability was assessed before and after the intervention using eight maximal 15-m freestyle sprints.

Interventions
Reduced-Volume High-Intensity Interval Swimming Training
The intervention lasted four weeks and included two supervised sessions per week. Main-set activities included intermittent 50-m swims with short recovery intervals, 25-m all-out sprints using a 1:1 work-to-recovery ratio, and five 30-s tethered maximal efforts with 2 min 30 s of recovery between efforts. The precise session content progressed according to the predefined training schedule.
Higher-Volume Moderate-Intensity Swimming Training
The active-comparator intervention lasted four weeks and included two supervised sessions per week. Participants completed 50-, 100-, and 200-m freestyle intervals at moderate intensity using the predefined work-to-recovery structure. Intensity was monitored using heart rate and rating of perceived exertion, targeting approximately 60%-75% of estimated maximum heart rate and moderate intensity ratings (e.g., 3-4) on the Borg CR10 scale. Main-set volume was approximately 50% greater than in the high-intensity intervention.
