Abstract

A high energy demand is required for training and racing in road cycling. The aim of this study is determine the association between daily fluid body changes and training load responses observed from monitoring elite road cyclists across the course of a competitive season.

Five professional cyclists participating in two training camps and two 5-days stage races. Body mass (BM) and BIA measurements  were performed each morning. Bioelectrical values were associated with vector length (VL) were used to indicate changes in total body water. Power output data were collected during every training session and race stage. Training load was calculated as the percentage of time spent in 4 zones: <100W, 100-300W, 300-500W, >500W  Training Peaks Software (Peaksware LLC, Lafayette, CO, USA) was used to analyse training data and calculate Normalized power (NP).

Significant negative correlations were found between: VL and BM (r=-.856 p<.001); VL and % time spent at 300-500W (r=-.335 p<.001); BM and time spent at 100-300W (r=-.352 p<.001); VL with NP (r=-,268 p<.01). Positive correlations were found between: VL and %time spent below 100W (r=.235 p<.05); VL and %time spent at 100-300W (r=.254 p<.01); BM and %time spent at 300-500W (r=.383 p<.001); BM and NP(r=.337 p<.001).

The main findings of this study are that body water content, changes according the preceeding effort sustained during training and racing.VL changes  could be used as a method to detect these small changes of body water content an subsequently identify the physiological effects of training load on the cyclist
