Background: The effects of pre-sleep protein supplementation on endurance athletes remain unclear, particularly whether its poten- tial benefits are due to the timing of protein intake or solely to an increased total protein intake. We assessed the effects of pre-sleep protein supplementation in professional cyclists during a training camp accounti...

We aimed to establish whether this relationship differs between cyclists of different performance levels or team roles. Methods: Mean maximal power (MMP) output data from 177 riders were obtained from 2012 to 2021 from training and competitions. Cyclists we...

Workload is calculated from exercise volume and intensity. In endurance sports, intensity has been measured using heart rate or RPE, giving rise to load indexes such as sRPE or TRIMP. In cycling, the advent of power meters led to new indexes, such as TSS. All these indexes have limitations, especially for high intensity exercise. Therefore, a new i...

TO THE EDITOR: Podlogar et al. (1) have nicely discussed cur- rent methods for classifying athletes in applied physiology studies attending to their training or performance level. We agree with them that relying on a single physiological marker such as maximum oxygen uptake is not without limi- tations and endorse the use of more performance-based...

Purpose: The functional threshold power (FTP), which demarcates the transition from steady state to non-steady-state oxidative metabolism, is usually determined with a 20-minute cycling time trial that follows a standard ∼45-minute warm-up. This study aimed to determine if the standard warm-up inherent to FTP determination is actually necessary an...

RESUMEN El ciclismo indoor (CI), es una de las actividades fitness más practicadas en los centros deportivos españoles.
