Summary:
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.

Primary Outcome Measures: Calorie expenditure in kilocalories (kcal), Oxygen consumption values will be used to calculate caloric expenditure (kcal) and fat oxidation (kcal) using the indirect calorimetry method., 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.|Fat oxidation in kilocalories (kcal), Respiratory exchange ratio (RER) and oxygen consumption values will be used to calculate fat oxidation (kcal) using the indirect calorimetry method., 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.
Secondary Outcome Measures: Heart rate in beats per minute (bpm), Heart rate is the number of heart beat 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.|Blood pressure in millimeters of mercury (mmHg), Both systolic blood pressure and diastolic blood pressure will be measured., 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).|Rate of perceived exertion, Rate of perceived exertion (RPE) is a subjective measure to indicate the participant's feeling about the exercise., 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 in the ear by using a digital ear thermometer., 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, The participant will fill out a survey on their feeling about exercising with each type of leggings, including their previous leggings-wearing experience and satisfaction level with tested leggings., 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.
