About this study
Official title: Effects of Different Inter-Set Rest Intervals on Indirect Markers of Muscle Damage and Mechanical Parameters After Flywheel Resistance Training in Untrained Men: A Randomized Parallel-Group Clinical Trial
This randomized parallel-group clinical trial will compare the acute effects of three different inter-set rest intervals during a single lower-limb flywheel resistance exercise session in untrained men. Participants will be randomly allocated to one of three groups: 1-minute, 2-minute, or 3-minute inter-set rest interval. The primary outcome will be the change in maximal voluntary isometric contraction of the knee extensors 48 hours after exercise. Secondary outcomes will include mechanical variables during the exercise session, countermovement jump performance, knee flexor maximal voluntary isometric contraction, muscle soreness, pressure pain threshold, range of motion, ultrasound-derived muscle thickness and echo intensity, perceived exertion, perceived discomfort, perceived recovery status, creatine kinase, and lactate dehydrogenase.
Read the detailed description
Participants will complete seven laboratory visits. The first two visits will be used for baseline assessments and test-retest reliability. The third and fourth visits will be used for technical familiarization with the flywheel exercises. The fifth visit will include the experimental flywheel resistance exercise session and immediate post-exercise assessments. The sixth and seventh visits will include follow-up assessments 48 and 96 hours after the experimental session, respectively. Blood samples for creatine kinase and lactate dehydrogenase will be collected before the experimental session and 72 hours after exercise in a partner laboratory.
The experimental session will include squat, Romanian deadlift, knee extension, and knee flexion exercises performed using flywheel devices. All groups will perform the same exercises, volume, inertia, and execution instructions. The only difference between groups will be the inter-set rest interval: 1 minute, 2 minutes, or 3 minutes.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in maximal voluntary isometric contraction of the knee extensors
Maximal voluntary isometric contraction of the knee extensors will be assessed using a load cell with the knee positioned at 90 degrees of flexion. The primary outcome will be the change in force between baseline and immediately, 48 hours, and 96 hours after the experimental exercise session using a flywheel.
Measured: Baseline, 10 minutes after the experimental exercise session, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session
Change in maximal voluntary isometric contraction of the knee flexors
The maximum voluntary isometric contraction of the knee flexors will be assessed using a load cell with the knee positioned at 45 degrees of flexion. The primary outcome will be the change in force between baseline and immediately, 48 hours, and 96 hours after the experimental exercise session using a flywheel.
Measured: Baseline, 10 minutes after the experimental exercise session, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session
Secondary outcomes (11)
Change in vastus lateralis and biceps femoris long head muscle thickness
Measured: Baseline, 10 minutes after the experimental exercise session, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session
Change in vastus lateralis and biceps femoris long head echo intensity
Measured: Baseline, 10 minutes after the experimental exercise session, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session
Change in countermovement jump performance
Measured: Baseline, 10 minutes after the experimental exercise session, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session
Change in active and passive knee flexion and extension range of motion
Measured: Baseline, 10 minutes after the experimental exercise session, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session
Change in lower-limb muscle soreness score assessed by the Visual Analogue Scale
Lower-limb muscle soreness will be assessed using a 100-mm Visual Analogue Scale. The scale ranges from 0 to 100, where 0 indicates no pain and 100 indicates the worst possible pain. Higher scores indicate greater muscle soreness. The outcome will be reported as the change in muscle soreness score from baseline to the post-exercise time points.
Measured: Baseline, 10 minutes after the experimental exercise session, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session
Change in pressure pain threshold of the thigh muscles
Measured: Baseline, 10 minutes after the experimental exercise session, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session
Change in serum creatine kinase and lactate dehydrogenase concentrations
Measured: Pre-exercise and 72 hours after the experimental exercise session
Peak concentric and eccentric power output during flywheel exercise
Peak concentric and eccentric power output will be recorded during each valid repetition of the flywheel exercise session using a load cell connected to the flywheel device. Data will be collected for all sets and exercises, excluding the initial preparatory repetitions. The outcome will be reported as peak concentric power, peak eccentric power, and eccentric/concentric power ratio across the experimental exercise session.
Measured: During all 16 sets performed in the experimental exercise session
Rating of perceived exertion assessed by the OMNI-Resistance Exercise Scale
Rating of perceived exertion will be assessed using the OMNI-Resistance Exercise Scale. The scale ranges from 0 to 10, where 0 indicates extremely easy and 10 indicates extremely hard. Higher scores indicate greater perceived exertion. The outcome will be reported after each set of the experimental flywheel exercise session and 10 minutes after the end of the session.
Measured: After each of the 16 sets performed during the experimental exercise session and 10 minutes after the experimental exercise session
Perceived discomfort assessed by the Discomfort Scale
Perceived discomfort will be assessed using a 0-to-100 Discomfort Scale. The scale ranges from 0 to 100, where 0 indicates no discomfort and 100 indicates maximal discomfort. Higher scores indicate greater perceived discomfort. The outcome will be reported after each set of the experimental flywheel exercise session and 10 minutes after the end of the session.
Measured: After each of the 16 sets performed during the experimental exercise session and 10 minutes after the experimental exercise session
Perceived recovery status assessed by the Perceived Recovery Status Scale
Perceived recovery status will be assessed using the Perceived Recovery Status Scale. The scale ranges from 0 to 10, where 0 indicates very poor recovery and 10 indicates full recovery. Higher scores indicate better perceived recovery. The outcome will be reported as the perceived recovery status score at baseline and at the post-exercise follow-up time points.
Measured: Baseline, 48 hours after the experimental exercise session, and 96 hours after the experimental exercise session

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This randomized parallel-group clinical trial will compare the acute effects of three different inter-set rest intervals during a single lower-limb flywheel resistance exercise session in untrained men. Participants will be randomly allocated to one of three groups: 1-minute, 2-minute, or 3-minute inter-set rest interval. The primary outcome will be the change in maximal voluntary isometric contraction of the knee extensors 48 hours after exercise. Secondary outcomes will include mechanical variables during the exercise session, countermovement jump performance, knee flexor maximal voluntary isometric contraction, muscle soreness, pressure pain threshold, range of motion, ultrasound-derived muscle thickness and echo intensity, perceived exertion, perceived discomfort, perceived recovery status, creatine kinase, and lactate dehydrogenase.
