The Claim

In well-trained male kayak sprint athletes, resistance-type and paddling-based high-intensity interval training improve 500-meter paddling performance by approximately 3.5–3.7 seconds, which is significantly greater than the 1.9-second improvement observed with endurance paddling.

In plain English

Among trained male kayak sprinters, high-intensity interval training using resistance or paddling exercises improves 500-meter race times by 3.5 to 3.7 seconds, while endurance paddling improves times by only 1.9 seconds.

See the scientific wording

In well-trained male kayak sprint athletes, both resistance-type and paddling-based high-intensity interval training improve 500-meter paddling performance by approximately 3.5–3.7 seconds, which is significantly greater than the 1.9-second improvement seen with endurance paddling.

Why this might work

Intense training makes the heart pump more blood with each beat and increases the number of muscle fibers that fire at full force, allowing the athlete to generate more power during short, maximum-effort paddling.

  1. Study: Effects of a New Form of Resistance-Type High-Intensity Interval Training on Cardiac Structure, Hemodynamics, and Physiological and Performance Adaptations in Well-Trained Kayak Sprint Athletes

    In elite kayak racers, two types of intense training—resistance exercises and high-speed paddling intervals—both made them about 3.5 seconds faster in a 500-meter race, while regular slow paddling only improved times by about 1.9 seconds. The study confirms this difference.
