REHIT Versus SMIT in Sedentary Young Women

Not Applicable

Completed

• Conditions: Sedentary Behavior
• Interventions: Other: Reduced-exertion high intensity training; Other: Short moderate intensity training

• Registration Number: NCT05875051
• Lead Sponsor: University of Valencia

Brief Summary

Reduced-exertion high-intensity training (REHIT) is a novel form of exercise known for being non-classical, time-efficient, and effective on different populations. However, REHIT was scarcely tested on sedentary women with mortality risks. The aim of the study is to compare the effects of REHIT versus short moderate-intensity training (SMIT) on functional capacity, resting heart rate (RHR), and activity enjoyment in sedentary young women.

Detailed Description

The aim of the study is to compare the effects of reduced-exertion high-intensity training (REHIT) versus short moderate-intensity training (SMIT) on functional capacity, resting heart rate (RHR), and activity enjoyment in sedentary young women. Therefore, sedentary young women will be randomly allocated to either a: i) REHIT group or ii) SMIT group. Both groups will perform an intervention over 6 weeks duration for 10 minutes each session for 2 sessions/week, but with different intensities (REHIT or SMIT). Both forms of exercise will be conducted on a cycle ergometer with the subjects monitored throughout the intervention. Before and after the 3-week intervention, functional capacity (6-minute walking test) and RHR will be measured. Additionally, physical activity enjoyment (Physical Activity Enjoyment Scale) will be assessed after the intervention.

Arm && Interventions

Group	Intervention	Description
Reduced-exertion high intensity training group	Reduced-exertion high intensity training	The REHIT part will consist of maximum cycling sprints of all-out exercise at 100% of the HRmax, increasing for up to 10 seconds, 15 seconds on week two and 20 seconds on week three.
Short moderate intensity training group	Short moderate intensity training	The SMIT part of the session will consist of 6 minutes of moderate intensity exercise at 60-70% HRmax.

Primary Outcome Measures

Name	Time	Method
Functional capacity	After the intervention (3 weeks)	It will be measured using the 6-minutes walking test (6MWT). Participants will be instructed to walk as quickly as possible along a 30-meter hallway for a duration of six minutes without running. Then, the distance in meters they cover will be registered. The greater the number of meters run, the better the functional capacity.

Secondary Outcome Measures

Name	Time	Method
Resting heart rate	After the intervention (3 weeks)	It will be measured with a patient monitor (ProAct PC-3000 Patient Monitor, Medisave, UK).
Physical activity enjoyment	After the intervention (3 weeks)	To assess enjoyment, a modified version of the Physical Activity Enjoyment Scale (PACES) will be used. In this questionnaire, 17 items are scored on a 7-point bipolar scale, with an overall enjoyment score ranging from 17 (not enjoyable) to 68 (neutral) and 119 (enjoyable).
