Brief Summary

This study will deliver a 9 week high intensity interval training (HIIT) class using functional movements within a community based gym. The class will be twice a week. Outcomes are focused on cardiovascular endurance, balance, strength and muscle size and muscle quality changes. The outcomes will be assessed weekly.

Detailed Description

We will measure cardiovascular endurance (2-minute Step Test; 2MST), balance (Functional Gait Assessment; FGA), muscular strength (Grip Strength and 5 times sit-to-stand; 5xSTS) and muscle size (thickness) and quality (echo intensity) on a weekly basis over the 9 week HIIT class.

High-Intensity Interval Training

Intervention Type: BEHAVIORAL

High-intensity interval training (HIIT) sessions will occur twice per week, on non-consecutive days. Each training session will last 45-60 minutes and consist of eight functional movement exercises incorporating the entire body (upper body, lower body, core/stability, cycling, and agility). Participants will complete two rounds of the 8-exercise circuit with 2-minutes of rest between rounds. The load/resistance used for each exercise will be self-selected by the participants that equates to 15-18 on the RPE scale. During each round, participants will have 1 minute to complete as many repetitions as possible of a given exercise and then have 1 minute of rest before completing the next exercise - giving the participants a 1:1 exercise-to-rest ratio.
