The Claim

In well-trained male kayak sprint athletes, 8 weeks of resistance-type high-intensity interval training using one-armed cable row at 100% vO2peak increases maximal oxygen uptake by 9.1% and increases one-repetition maximum upper body strength by 1.7 standard deviations.

In plain English

In well-trained male kayak sprinters, 8 weeks of high-intensity resistance training using one-armed cable rows increases maximal oxygen uptake by 9.1% and increases upper body strength by 1.7 standard deviations.

See the scientific wording

In well-trained male kayak sprint athletes, 8 weeks of resistance-type high-intensity interval training (RHIIT) using one-armed cable row at 100% vO2peak improves maximal oxygen uptake (VO2peak) by 9.1% and increases one-repetition maximum strength in the upper body by 1.7 standard deviations, demonstrating that a single-mode resistance-based HIIT protocol can simultaneously enhance both cardiorespiratory fitness and muscular strength.

Why this might work

Intense rowing workouts force the heart to pump more blood with each beat by filling it more fully and squeezing harder, which delivers more oxygen to muscles. At the same time, the heavy resistance triggers nerves to activate more muscle fibers and signals muscles to grow larger, making them stronger. These two changes happen together during the same training sessions.

  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

    This study showed that elite kayak athletes who did eight weeks of intense one-armed rowing workouts got both better at endurance (their oxygen use went up 9.1%) and stronger in their upper bodies (strength jumped by 1.7 times more than before), proving one type of workout can improve two things at once.
