Velocity-Based Resistance Training Effects on Inflammation in Older Adults

4. května 2026 aktualizováno: National Taipei University

Dose-Response Effects of Velocity-Based Resistance Training on Anti-Inflammatory Responses in Older Adults

This study aims to investigate the effects of resistance training (RT) with different training volumes on immune modulation and anti-inflammatory responses in older adults. Participants will be randomly assigned to one of three RT volume groups (low, medium, or high) or a non-exercise control group. Participants in the training groups will complete a 4-week RT program, followed by a 4-week detraining phase. The findings are expected to provide evidence for volume-specific RT prescriptions to support healthy aging.

Intervence / Léčba
Experimentální: low training volume resistance exercise
Participants assigned to the low-volume resistance training group will perform one set per exercise at a load corresponding to 80% of 1RM. Each set will be terminated when movement velocity decreases by 30% from the first repetition. Rest intervals of 2-3 minutes will be provided between exercises.
The RT program will consist of 12 sessions over a 4-week period, with participants training three times per week and at least one rest day between sessions. All sessions will be supervised by research personnel to ensure proper technique and safety. Exercises will be performed using resistance machines and will include chest press, shoulder press, seated row, lat pulldown, and leg press.
Experimentální: medium training volume resistance exercise
Participants assigned to the medium-volume resistance training group will perform three sets per exercise at 80% of 1RM. Each set will be terminated when movement velocity decreases by 30% relative to the first repetition. Rest intervals of 90 seconds will be provided between sets, and 2-3 minutes between exercises.
The RT program will consist of 12 sessions over a 4-week period, with participants training three times per week and at least one rest day between sessions. All sessions will be supervised by research personnel to ensure proper technique and safety. Exercises will be performed using resistance machines and will include chest press, shoulder press, seated row, lat pulldown, and leg press.
Experimentální: high training volume resistance exercise
Participants assigned to the high-volume resistance training group will perform five sets per exercise at 80% of 1RM. Each set will be terminated when movement velocity decreases by 30% relative to the first repetition. Rest intervals of 90 seconds will be provided between sets, and 2-3 minutes between exercises.
The RT program will consist of 12 sessions over a 4-week period, with participants training three times per week and at least one rest day between sessions. All sessions will be supervised by research personnel to ensure proper technique and safety. Exercises will be performed using resistance machines and will include chest press, shoulder press, seated row, lat pulldown, and leg press.
Žádný zásah: sedentary control
Participants in control trial stayed sedentary during the period.
