简要总结
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.

盲法说明
All pre- and post-testing is completed by researchers not involved in training, and thus are blinded to which group participants are assigned to. This prevents any potential bias when researchers are completing post-testing sessions.

结局指标
主要结局
Cardiorespiratory fitness
时间窗: This will be assessed before and after 4 weeks of training (or control).
Cardiorespiratory fitness will be assessed through the measurement of maximal oxygen consumption. This will be determined using an incremental exercise test to volitional fatigue on a treadmill. A metabolic cart will be used to assess oxygen consumption using indirect calorimetry
次要结局
- Anaerobic performance(This will be assessed before and after 4 weeks of training (or control).)
