Effect of Interval and Resistance Exercise on Physiological and Psychological Parameters.

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to examine the physiological and psychological effects of a sprint interval and resistance training intervention on females.

Detailed Description
-----------------
Females aged 20-65 will attend 10 weeks of exercise training consisting of sprint interval training and resistance training for 30 sessions. We will examine changes in body composition, blood panel (fasting glucose, cholesterol, triglycerides), strength (bench press and back squat), aerobic capacity and psychological parameters (hardiness, affect, enjoyment, perception and self-regulation). The effects will be measured acutely after the program and 6-months after the cessation of the program.
