Brief Summary

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

The aerobic fitness is important for mountain bikers, but riders should also be able to generate maximal and supramaximal efforts in some crucial phases of the competition. Although there is an increase interest in high-intensity aerobic training, to investigators knowledge, there are no studies examining the effects of interval (INTV) or intermittent training (INTM) in mountain bikers. The aim of this study was to compare the effects of INTV and INTM on aerobic fitness variables (peak power output, Wmax, lactate threshold, and onset of blood lactate accumulation) but more importantly on performance as measured using a controlled mountain bike race, i.e. simulation. The investigators hypothesized that INTV and INTM training were equally effective in improving Wmax, Lactate threshold and onset of blood lactate accumulation, but INTV was superior in enhancing performance in mountai bike race simulation.This hypothesis is due to studies that have shown higher gains in performance with long duration of aerobic high intensity interval training in comparison to the shorter training at a higher intensity.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Interval Training

The INTV consisted of 7 to 10 repetitions of 4-6 min at the highest intensity sustainable, and in the last 30 s of each repetition was performed a maximal sprint, the active recovery was 4-6 min in intensity from 10 to 15 of scale of perceived exertion CR100.

Group Type EXPERIMENTAL

Interval Training

Intervention Type OTHER

The interval training group consisted of 7 to 10 repetitions of 4-6 min at the highest intensity sustainable, the active recovery was 4-6 min in intensity from 10 to 15 of scale of perceived exertion CR100.

Intermittent Training

The riders completed 8 to 12 repetitions of 30 s all-out with 4 min of active recovery (10-15 on the CR100 scale).

Group Type EXPERIMENTAL

Intermittent Training

Intervention Type OTHER

The riders of intermittent training group completed 8 to 12 repetitions of 30 s all-out with 4 min of active recovery.
