Brief Summary

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

The purpose of this study is to investigate the effects of high-intensity functional training (HIFT) as compared to traditional resistance training (RT) and concurrent training consisting of RT and high-intensity interval training (HIIT) on physical performance metrics, body composition, and mental and physical readiness of tactical personnel.

Detailed Description

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

This study assesses the impact of 8-weeks of high-intensity functional training (HIFT) as compared to traditional resistance training (RT) and concurrent training consisting of RT and high-intensity interval training (HIIT) on various performance outcomes. The main questions the study aims to answer are:

* Evaluate the distinct effects of HIFT, RT, and RT plus HIIT over eight weeks on physical performance and body composition measures in tactical men and women.
* Determine the distress, training load, and physical readiness associated with each of the three distinct training interventions over eight weeks.

Participants will:

* Take part in 10-weeks total of study-related activity.
* Complete four total sessions of pre and post-testing sessions, which include body composition, maximal oxygen uptake testing (VO2max), upper and lower body maximal strength, and lower body power.
* Be randomly assigned to an exercise training intervention.
