简要总结
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.
详细描述
The PI will verify age with a drivers license or other form of identification to ensure that the study participants are at least 18 years of age to participate. After obtaining consent, the PI will then administer a pre-exercise screening tool, the Physical Activity Readiness Questionnaire for Everyone, to the participant for them to complete in order to aid in determining study eligibility. If the participant is deemed eligible, 3 other questionnaires will be emailed to participants for completion: Physical Activity Enjoyment Scale, Exercise Self-efficacy Scale, and the International Physical Activity Questionnaire (IPAQ) short form. Given that the participants will be instructed to not change any physical activity habits outside of the study, the IPAQ will be used to control for this pre- and post-intervention and weekly throughout the duration of the intervention. All forms must be completed and submitted to the PI prior to further data collection. Data collection will consist of a (1) blood collection visit, (2) exercise testing and abdominal/visceral fat measurement session, (3) three exercise/movement familiarization sessions (only conducted pre-intervention), (4) three strength, muscular endurance, and muscular power testing sessions before and after the intervention, and 12 weeks of training three times per week as described below. Excluding the consent obtaining meeting, participants will attend 8 sessions prior to beginning the intervention as detailed below. During the intervention, participants will be wearing heart rate monitors in order to monitor their training intensity. The PI will lead all data collection procedures with the assistance of School of Health Science students and Dr. Myung Choi except for the blood collection and analysis which will be supervised by Dr. Kristen Landis-Piwowar. All measures will be assessed pre- and post-intervention. Blind copy emails will be sent to remind the participants about upcoming data collection sessions and to schedule a data collection appointment.
Day 1: Prevention Research Center (blood collection visit)
Following 12-hr fast, assessments include:
- weight, height, waist circumference
- resting heart rate
- blood pressure
- venipuncture (blood sugar and fat)
- blood analysis
Day 2: Prevention Research Center (exercise testing and visceral fat visit)

入选标准
- •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.
排除标准
- •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.
研究组 & 干预措施
Multimodal
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.
干预措施: Multimodal High-Intensity Interval Training Intervention (Other)
Rowing
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.
干预措施: Multimodal High-Intensity Interval Training Intervention (Other)
Control
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.
结局指标
主要结局
Aerobic fitness
时间窗: 15 minutes
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.
次要结局
- Physical Activity Enjoyment scale(5 minutes)
- Triglycerides(10 minutes)
