Summary
Functional resistance training (FRT) significantly improved autonomic modulation and reduced blood pressure in individuals with metabolic syndrome (MetS). This approach offers greater benefits than conventional resistance training (CRT) for managing MetS complications.
Area of Science:
- Exercise Physiology
- Cardiovascular Health
- Metabolic Disorders
Background:
- Metabolic syndrome (MetS) is a widespread condition linked to elevated blood pressure (BP) and autonomic dysfunction.
- While functional resistance training (FRT) shows promise for muscle fatigue and pain, its specific effects on autonomic modulation (AM), BP, and heart rate in MetS patients remain unclear.
- This study investigates whether FRT offers superior benefits compared to conventional resistance training (CRT) in individuals with MetS.
Purpose of the Study:
- To compare the effects of FRT and CRT on autonomic modulation (AM), blood pressure (BP), heart rate (HR), and muscle strength in individuals with MetS.
- To determine if FRT is more effective than CRT in improving cardiovascular and autonomic parameters in this population.
Main Methods:
- Thirty-eight individuals (40-60 years) with MetS were randomized to either FRT or CRT groups.
- Training involved 3 sessions per week for 30 sessions, with intensity gradually increasing from 30% to 100% of one maximal repetition (1MR).
- Outcomes, including AM (via heart rate variability), BP, HR, and muscle strength (1MR), were assessed at baseline and post-intervention.
Main Results:
- The FRT group exhibited a significant increase in cardiac parasympathetic activity compared to the CRT group (RMSSD ∆40%, SD1 ∆39%, HF ms 2 ∆80%).
- Only the FRT group demonstrated a significant reduction in both systolic and diastolic blood pressure post-intervention.
- Both training modalities resulted in similar improvements in muscle strength, with no significant changes in heart rate observed in either group.
Conclusions:
- Progressive functional resistance training (FRT) is more beneficial than conventional resistance training (CRT) for enhancing autonomic modulation, specifically increasing vagal activity.
- FRT effectively reduces blood pressure in individuals with metabolic syndrome.
- These findings suggest FRT as a superior exercise modality for managing key cardiovascular risk factors associated with MetS.
