Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We sought to investigate the effects of 4 weeks of 16/8 time restricted eating (TRE) with windows of 16 hours of fasting and 8 hours of eating) on elite cyclists' performance, metabolic and blood parameters.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sixteen elite under-23 cyclists were randomly assigned to a TRE group or to a control group (CTRL) with a traditional meal pattern. The TRE group consumed 100% of its estimated daily energy needs in an 8-hour time window: from 10:00 AM (ante meridiem) to 6:00 PM (post meridiem) whilst the CTRL group consumed 100% of its estimated daily energy needs in 3 meals between 7:00 AM and 9:00 PM. During the experimental period, training loads were similar in the two groups. Athletes were tested before and after 4 weeks of the intervention. Body composition , basal metabolism, performances indexes and blood parameters were measured.
