Low-Volume High-Intensity Race-Pace Training in Finswimmers

This single-group case series describe individual responses to a 9-week low-volume, high-intensity race-pace training block in 5 finswimmers from the Antioquia Underwater Activities League (LASA), Colombia. The intervention will be oriented towards race-specific swimming paces and will include repeated swimming efforts prescribed according to each athlete's main competitive event. External training load, heart rate, rating of perceived exertion, pace stability, and sport performance were monitored throughout the block. The primary outcome was the change in performance time in each athlete's main competitive event from baseline to post-intervention. The study used an intra-individual descriptive approach and did not include randomisation, a control group, or causal inference.
