简要总结
The primary aim of this study is to investigate the impact of incorporating shortened resistance bands (SRB) into leggings on cardiovascular responses and caloric expenditure during exercise in young, healthy women. This study will employ a randomized, controlled, and double-blind crossover design involving four types of exercise: walking, climbing, rowing, and cycling. Participants will perform each type of exercise for 10 minutes while wearing either SRB leggings or leggings without SRB, with sessions on separate days and about 3 days apart. The cardiovascular and metabolic responses will be measured during and after the exercise.
详细描述
This study will employ a randomized, controlled, and single-blind crossover design involving stair climbing, rowing, and cycling exercises for 10 minutes while wearing either SRB leggings or leggings without SRB (control leggings) on separate days (with at least three days in between). The goal is to compare the metabolic and cardiovascular responses of exercising with different types of leggings.
Participants will be randomly assigned to wear either SRB leggings or control leggings first and then switch to the other type of leggings for the exercise testing on a separate day. The sequence of exercises will also be randomized for each participant but will remain consistent for each participant. The participants, technicians, and PIs will be blinded as to which type of leggings were used on a given day, with leggings being coded as "A" or "B" and provided prelabeled by SweetflexxTM company.
The study will consist of three laboratory visits:
- Laboratory visit 1 (Visit 1): Screening, informed consent, health-related questionnaires, familiarization, exercise pace determination, and legging size fitting. This visit will take 1 hour.
- Laboratory visit 2 (Visit 2): Walk on the treadmill, climb on the StairMaster, row on a rowing ergometer, and cycle on a bicycle ergometer with one type of leggings. This visit will take 2 hours.
- Laboratory visit 3 (Visit 3): Repetition of walking on the treadmill, climbing on the inclined StairMaster, rowing on a rowing ergometer, and cycling on a bicycle ergometer with another type of leggings. This visit will take 2 hours.

结局指标
主要结局
Calorie expenditure in kilocalories (kcal)
时间窗: The oxygen consumption will be monitored during four 10-minute exercises (i.e., rowing, walking, climbing and cycling) and the 10-minute recovery period following the completion of each 10-minute exercise.
Oxygen consumption values will be used to calculate caloric expenditure (kcal) and fat oxidation (kcal) using the indirect calorimetry method.
Fat oxidation in kilocalories (kcal)
时间窗: The oxygen consumption and respiratory exchange ratio will be monitored during four 10-minute exercises (i.e., rowing, walking, climbing and cycling) and the 10-minute recovery period following the completion of each 10-minute exercise.
Respiratory exchange ratio (RER) and oxygen consumption values will be used to calculate fat oxidation (kcal) using the indirect calorimetry method.
次要结局
- Blood pressure in millimeters of mercury (mmHg)(Systolic blood pressure and diastolic blood pressure will be monitored at baseline and every two minutes during the 10-minute recovery period following each 10-minute exercise (i.e., rowing, walking, climbing and cycling, respectively).)
- Heart rate in beats per minute (bpm)(Heart rate will be monitored at baseline, during four 10-minute exercises (i.e., rowing, walking, climbing and cycling), and the 10-minute recovery period following the completion of each 10-minute exercise.)
- Rate of perceived exertion(RPE will be measured every minute during four 10-minute exercises (i.e., rowing, walking, climbing and cycling).)
- Core temperature in Celsius (°C)(The core temperature will be measured at baseline and every two minutes during 10-minute recovery period following each 10-minute exercise (i.e., rowing, walking, climbing and cycling, respectively).)
- Leggings evaluation(Participants will fill out a leggings evaluation survey immediately after the last 10-minute recovery period following the completion of the fourth/last 10-minute exercise bout.)
