To describe the pacing pattern of 400m freestyle swimmers, understand how athletes select the first half compared to their 200-m race pace, and correlate critical speed (CS) and D’ with pacing parameters. The best all-time 400m performances were obtained, and 200m performances were retrieved from the same competition. Twenty-four performances were...

This study compared the in-water bilateral leg kick speed difference between a Paralympic and an Olympic athlete. The Paralympic (former S10) was not eligible after his reclassification in 2019, whereas the Olympic was a semi-finalist in 50 m freestyle in Rio 2016. Kick performance was assessed by a speedometer in one push-off ∼15 m maximal kick sp...

This study investigated the effects of a 4-week training with hand paddles (HPD) on front-crawl swimming performance (SP), clean swimming speed (SPEED), stroke rate (SR), stroke length (SL) and tethered force (TF). Twenty swimmers (10 men and 10 women) were paired according to performance and gender, and were randomly assigned to control (CON, 22.4...

O objetivo deste estudo foi comparar a coordenação do nado borboleta de jovens nadadores em diferentes estágios maturacionais.
