# How does a simulated high-intensity functional training competition influence on stress, recovery and muscle power?

## TL;DR

This study examines how a simulated high-intensity functional training competition affects stress, recovery, and muscle power in participants.

## Contribution

The study evaluates the specific effects of a simulated HIFT competition on stress, recovery, and muscle power in experienced participants.

## Key findings

- HIFT_C increases somatic complaints and impairs sleep quality.
- HIFT_C reduces participants' perception of success.
- Upper limb muscle power increases during specific competition phases.

## Abstract

High-intensity functional training (HIFT) has increased the number of practitioners who find in the modality a way to improve their health levels. HIFT sessions are called “Workout of the day” (WODs), and in addition to training sessions, some practitioners choose to participate in competitions (HIFT_C). Competitions are held on consecutive days and can raise stress levels and affect recovery. The aim of study was to evaluate the effects of a simulated HIFT_C on markers of stress, recovery, and muscle power. Fifteen men with experience in HIFT_C, participated. The HIFT_C was held over 2 days, 2 WODs on each day, and 2 h between WODs. Levels of general stress, and physical and emotional recovery were assessed using the RESTQ-Sport Questionary 48 h before and 24 h after the HIFT_C. The muscle power in the lower and upper limbs were assessed through the height of the Countermoviment Jump (CMJ) and medicine ball throw distance (AH), respectively. The results showed increases in somatic complaints, a reduction in success, and a reduction in sleep quality. In power parameters, when compared with baseline, we observed increase in AH in Pre-WOD 2, Post-WOD 3, Pre-WOD 4 and Post-WOD 4. We conclude that HIFT_C increases somatic complaints, reduces the perception of success, and impairs sleep quality and increases in power in the upper limbs.
