Sex-Specific Accumulated Oxygen Deficit During Short- and Middle-Distance Swimming Performance in Competitive Youth Athletes.

Introduction: Since sex-specific accumulated oxygen deficit (AOD) during high-intensity swimming remains unstudied, this study aimed to assess AOD during 50, 100, and 200 m front-crawl performances to compare the responses between sexes and analyse the effect of lean body mass (LBM).

Methods: Twenty swimmers (16.2 ± 2.

The reliability of back-extrapolation in estimating in different swimming performances at the severe-intensity domain.

The amount of anerobic energy released during exercise might modify the initial phase of oxygen recovery (fast-O) post-exercise. Therefore, the present study aimed to analyze the reliability of peak oxygen uptake estimate by back-extrapolation under different swimming conditions in the severe-intensity domain, verifying how the alterations of the recovery profile and anerobic energy demand might affect values. Twenty swimmers (16.

Physiological Responses During High-Intensity Interval Training in Young Swimmers.

This study analyzed whether 100- and 200-m interval training (IT) in swimming differed regarding temporal, perceptual, and physiological responses. The IT was performed at maximal aerobic velocity (MAV) until exhaustion and time spent near to maximalVO peak oxygen uptake (⩒Opeak), total time limit (t), peak blood lactate [La] peak, ⩒O kinetics (⩒OK), and rate of perceived exertion (RPE) were compared between protocols. Twelve swimmers (seven males 16.
