Study Overview
Brief Summary
Randomized, controlled, double-blind, crossover clinical trial, depending on the product consumed, to analyze the efficacy on physical performance of a sports supplement consumed prior to and during competition or training.
Detailed Description
Subjects who meet the selection criteria will be randomly assigned to each of the study groups (investigational product or placebo, depending on the group to which they have been assigned). On the second day, participants will consume the product that subjects did not consume on the first day.
The product to be consumed will be ketone monoester. Participants will consume 800 mg/kg body weight, distributed in two intakes. The first one, half an hour before exercise and the same dose will be consumed one hour and a half after the first dose. The intakes will be accompanied by carbohydrates and bicarbonate.
The tests that the cyclists will perform are a time trial on a cycloergometer to measure performance, as well as a 30" sprint. Afterwards, the cyclists will do a 4 and a half hour training session at competition pace. After this training session, the participants will do the same time trial and the 30'' sprint.

Outcomes
Primary Outcomes
Physical performance
Time Frame: Change in performance after product consumption and training at a competitive level
Measured using a power roller. Variables such as maximum power and average power
Secondary Outcomes
- Blood glucose(It will be measured on a daily basis. Measurements will begin two days before the first performance test and end one day after the completion of the performance tests.)
- Heart Rate(It will be measured on four different occasions. Two on the first day (after one intake of product and after a second intake and training at competitive pace) and 4 days later, the same measurements but with the opposite product.)
- Ketone(It will be measured on four different occasions. Two on the first day (after one intake of product and after a second intake and training at competitive pace) and 4 days later, the same measurements but with the opposite product.)
- Heart rate variability(It will be measured every morning. Measurements will be started two days before the first performance test and finished one day after the end of the performance tests.)
- Fatigue(It will be measured on four different occasions. Two on the first day (after one intake of product and after a second intake and training at competitive pace) and 4 days later, the same measurements but with the opposite product.)
- Microcapillary blood(It will be measured on four different occasions. Two on the first day (after one intake of product and after a second intake and training at competitive pace) and 4 days later, the same measurements but with the opposite product.)
- Lactate(It will be measured on four different occasions. Two on the first day (after one intake of product and after a second intake and training at competitive pace) and 4 days later, the same measurements but with the opposite product.)
- Stomach test(It will be measured on four different occasions. Two on the first day (after one intake of product and after a second intake and training at competitive pace) and 4 days later, the same measurements but with the opposite product.)
