Study on the effect of full body isometric resistance training on cardiovascular pressure response.
Study Goal
The researchers aimed to determine the effects of different isometric resistance training (IRT) protocols on blood pressure improvement in overweight or obese college students.
Results Summary
Long-term IRT intervention significantly reduced systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) in multiple groups, while acute exercise temporarily increased cardiovascular responses without excessive pressure.
Population
Overweight or obese college students with irregular exercise habits.
Effective Dosage
Exercise intervention three times a week.
Duration
6 weeks.
Interactions
None mentioned.

BACKGROUND AND AIMS: Exploring the effect of different isometric resistance training (IRT) on improving blood pressure, so as to provide important reference for the design of aerobic exercise prescription for IRT to improve blood pressure. METHODS: Forty eight overweight or obese college students with irregular exercise habits were randomly divided into four groups and underwent exercise intervention three times a week for a total of 6 weeks. Cardiovascular changes were evaluated before the first and 18th exercise sessions, as well as 0, 30, and 60 min after exercise. RESULTS: Heart rate (HR) of equal distance wall squat group (ISG) and whole body equal length exercise group (WIG) increased significantly immediately after exercise, but long-term IRT intervention significantly decreased systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) of WIG and ISG, SBP, and MAP of equal grip strength group (IHG), and DBP and MAP of equal curl up group (ICG); In the first exercise, ICG, ISG, and WIG significantly increased SBP and DBP immediately after exercise, ISG significantly increased MAP immediately after exercise, while in the 18th exercise, IHG, ISG, and WIG significantly increased SBP immediately after exercise, ISG significantly increased DBP and MAP immediately after exercise. CONCLUSION: IRT is a safe and easy to implement exercise mode. Long-term intervention can effectively control blood pressure, and will not cause excessive cardiovascular pressure response after a single exercise.
