Study Details

Brief summary:

The goal of this study is to learn how the number of weekly exercise sessions affects improvements in fitness in healthy university aged students. The main question it aims to answer is how training frequency affects improvements in fitness. Participants will complete a pre-testing sessions to assess fitness level and sprint performance. Following this participants are assigned to one of four groups. A group that exercises 2 days a week, a group that trains 3 days a week, a group that trains 4 days a week, or a no-exercise control group. Participants in this group will not complete any training and allow the researchers to compare the exercise groups to a group that didn't train. Each participant will train for 4 weeks. During each training session participants will complete 4-6 30 second all-out sprints with 4 minutes of rest between each. Participants will complete the same tests they did during the pre-testing session following the 4 weeks of training to see how frequency affects improvements.

Interventions and Outcome Measures

Arms

experimental: 2 days per week group

Participants in this group complete 2 training sessions each week (Monday and Thursday).

experimental: 3 days per week group

Participants in this group complete 3 training sessions each week (Monday, Wednesday, and Friday).

experimental: 4 days per week group

Participants in this group complete 4 training sessions each week (Monday, Tuesday, Thursday, and Friday).

no intervention: No-exercise Control group

This group does not complete any training intervention. They are asked to maintain their regular physical activity habits.

Interventions

Exercise Intervention

Participants will complete an exercise intervention where they will exercise 2, 3, or 4 days per week for 4 weeks.

Primary outcome measure

  • Cardiorespiratory fitness [ Time Frame: This will be assessed before and after 4 weeks of training (or control). ]
