Brief Summary

Recently, it has been demonstrated that multimodal high-intensity interval training (MM-HIIT) (utilizing resistance-based and functional movements) can produce similar aerobic adaptations compared to high-intensity interval training (HIIT) using rowing but with greater muscle performance in females. In addition, HIIT has been shown to be more enjoyable than continuous training, and this may lead to enhanced self-efficacy and increased physical activity. To the investigators' knowledge, however, the cardiometabolic effects (blood pressure, abdominal/visceral fat, blood sugar, blood lipids/fats) of MM-HIIT have not been reported. The investigators aim to compare MM-HIIT with HIIT using a traditional aerobic fitness exercise (rowing) for the degree of cardiometabolic, physical performance (strength, endurance, power), and psychosocial (self-efficacy and enjoyment) adaptations. They will also determined sustained effects of the intervention by completing a 9-month follow-up.

Outcome Measures

Primary Outcomes (1)

• Aerobic fitness

  Aerobic fitness will be directly assessed by a VO2max bicycle test. Each participant will be allowed to warm-up on the bicycle for 5 minutes at a low intensity. The VO2max bicycle test will include 3 minute stages with increasing intensity each stage of 30 - 60 watts. The required cadence will be maintained at 60 RPMs (revolutions per minute) for each stage. The test will be terminated at volitional fatigue defined as the participant no longer able to maintain 60 RPMs for 20 seconds after encouragement from the testers. For most people, the test will take approximately 10 minutes.

Study Arms (3)

Multimodal

EXPERIMENTAL

Multimodal High-Intensity Interval Training Intervention. This group will train using multimodal exercises for 5 sets of 60 seconds of all out work, followed by 3 minutes of rest. Each session will have the same exercises within each set, but every session will be different than the others for movements utilized. There will be three movements used in each set. The first movement will be a strength movement for 4-6 repetitions. The second movement follows the first immediately and is a faster body weight or light implement power movement for 6-8 repetitions. The third movement follows the second immediately and is a very fast, sprint-like movement for the remainder of the 60 seconds. The intent of each set is to be completed with as much effort as possible across the full 60 seconds.

Other: Multimodal High-Intensity Interval Training Intervention

Rowing

ACTIVE COMPARATOR

Multimodal High-Intensity Interval Training Intervention. This group will train using a rowing ergometer for 5 sets of 60 seconds of all out work, followed by 3 minutes of rest (a total of 20 minutes each session). Each training session will be the same across the 12 weeks. The intent of each set is to be completed with as much effort as possible across the full 60 seconds.

Other: Multimodal High-Intensity Interval Training Intervention

Control

NO INTERVENTION

Multimodal High-Intensity Interval Training Intervention. This group will be instructed to continue with any activity they were involved in prior to the study and to not begin any new exercise programs during the course of the study. To incentive participation in this group, the control group will be offered the MM-HIIT intervention the following semester at no cost.

Interventions

Multimodal High-Intensity Interval Training Intervention OTHER

The intervention will occur 3 times per week for 12 weeks and include a warm-up, MM-HIIT or R-HIIT training protocol, and a cool down.

Eligibility Criteria

• Age: 18 Years - 40 Years
• Sex: female
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Potential participants will be non-obese (waist circumference ≤ 88 cm) recreationally active females aged 18 - 40 years who do not engage in a regular training program. Recreationally active is defined as periodically participating in physical activity or exercise between 1 - 3 hours a week for at least a month, but not involved in a systematic endurance or weight training activity.

You may not qualify if:

• Potential participants will be excluded if they have a history of exercise-limiting cardiovascular, respiratory, metabolic, or musculoskeletal illness/injury or if they are currently taking medication that would alter the physiological responses to exercise. They will also be excluded if they are pregnant or have a history of fainting while giving blood.
