Brief Summary

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

The goal of this randomized controlled trial is to compare adherence to training prescription-defined as the percentage of time spent within the prescribed intensity zone-using either a race pace-based method or a heart rate-based method in male and female recreational distance runners.

The main research questions are:

* Which training prescription method leads to greater adherence in recreational runners?
* Which method results in more accurate execution of low- and high-intensity interval training sessions?

Participants will undergo anthropometric and physiological assessments to determine training zones based on ventilatory thresholds. In addition, a 5-km time trial will be performed on a standard track to establish individual race pace zones.

Study Groups

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

Race Pace Group

Participants follow a training program based on race pace zones, including both low-intensity sessions and high-intensity intervals.

Group Type EXPERIMENTAL

Race Pace-based training

Intervention Type OTHER

Participants complete one week of endurance training based on race pace zones individually determined from a 5-km time trial performance. The program includes both low-intensity continuous runs and high-intensity interval training sessions.

Heart Rate Group

Participants follow a training program based on heart rate zones, including both low-intensity sessions and high-intensity intervals.

Group Type EXPERIMENTAL

Heart Rate-Based Training

Intervention Type OTHER

Participants complete one week of endurance training based on heart rate zones individually determined from ventilatory threshold assessments. The program includes both low-intensity continuous runs and high-intensity interval training sessions.
