High-Intensity Interval Training in a Community Gym

High-Intensity Interval Training in a Community Gym

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.

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.

Inclusion Criteria:

• no contraindications to exercise (PAR-Q+)
• do not have severe mental impairment (>14 on the SAGE)
• ability to walk 100 ft without the use of an assistive device
