Concentric vs Eccentric Exercise in Blood Flow Restriction Training
Comparison of the Effectiveness of Concentric and Eccentric Exercises in Blood Flow Restriction Training
This randomized controlled trial will investigate the effects of blood flow restriction (BFR) training combined with concentric or eccentric exercise on upper extremity reaction speed, muscle strength, and muscle oxygenation in healthy adults aged 18-35 years. A total of 34 participants will be randomly allocated to either a BFR combined with concentric exercise group (n=17) or a BFR combined with eccentric exercise group (n=17).
Before the intervention, maximal muscle strength will be determined using a one-repetition maximum (1RM) test for the dominant elbow flexor muscles. Upper extremity reaction speed will be assessed using the Nelson Hand Reaction Test. Biceps brachii muscle strength will be measured with a digital dynamometer, and muscle oxygenation will be evaluated using a near-infrared spectroscopy (NIRS) device. All outcome measures will be obtained 72 hours before the intervention and repeated 72 hours after completion of the training program by the same investigator.
The findings of this study will contribute to understanding whether concentric or eccentric exercise combined with BFR training provides greater improvements in upper extremity reaction speed, muscle strength, and muscle oxygenation in healthy individuals.

Aktywny komparator: CONCENTRIC GROUP
|
Participants assigned to this group will perform blood flow restriction (BFR) training combined with concentric elbow flexion exercises using the dominant upper extremity.
Training will be performed three times per week for four weeks (12 sessions).
Exercises will be performed at 20-30% of one-repetition maximum (1RM) using a pneumatic cuff applied to the proximal upper arm.
The cuff pressure will be set at 50% of the individual's arterial occlusion pressure.
Each session will consist of four sets (30-15-15-15 repetitions) with 30-second rest intervals between sets.

Upper Extremity Reaction Time
Ramy czasowe: Baseline (72 hours before the intervention) and 72 hours after completion of the 4-week intervention.
|
Upper extremity reaction time will be assessed using the Nelson Hand Reaction Test.
Participants will complete five trials, the highest and lowest values will be discarded, and the mean of the remaining three trials will be used for analysis.
Reaction time will be calculated from the ruler drop distance using the standard equation.

Biceps Brachii Muscle Strength
Ramy czasowe: Baseline (72 hours before the intervention) and 72 hours after completion of the 4-week intervention.
|
Biceps brachii muscle strength will be measured using an ActivForce 2 digital dynamometer.
Three maximal isometric contractions will be performed with 30-second rest intervals, and the highest value will be used for analysis.
