Isometric Exercise for Delayed Onset Muscle Soreness
13 juni 2026 uppdaterad av: Onur Atakan Sekibağ, Istanbul Nisantasi University
Effects of Isometric Exercise on Recovery Following Experimentally Induced Delayed Onset Muscle Soreness: A Randomized Controlled Trial
The goal of this clinical trial is to learn whether isometric exercise can improve recovery following experimentally induced delayed onset muscle soreness (DOMS) in healthy young adults.
The main questions it aims to answer are:
- Does isometric exercise reduce pain associated with delayed onset muscle soreness?
- Does isometric exercise improve pressure pain threshold, knee joint range of motion, muscle strength, and recovery following delayed onset muscle soreness?
Researchers will compare participants performing an isometric exercise program with a control group receiving no intervention to determine whether isometric exercise improves recovery after experimentally induced DOMS.
Participants will:
- Undergo a standardized exercise protocol to induce delayed onset muscle soreness.
- Be randomly assigned to either an isometric exercise group or a control group.
- Complete assessments of pain intensity, pressure pain threshold, knee range of motion, muscle strength, and thigh circumference.
- Be evaluated before exercise, immediately after exercise, and on Days 1, 3, and 5 following DOMS induction.

Detaljerad beskrivning
Delayed onset muscle soreness (DOMS) is a common consequence of unaccustomed or high-intensity physical activity, particularly exercises involving eccentric muscle contractions. DOMS is characterized by pain, tenderness, temporary reductions in muscle function, decreased range of motion, and impaired physical performance, typically peaking between 24 and 72 hours after exercise.
Various recovery strategies have been investigated to reduce the symptoms of DOMS; however, evidence regarding the effectiveness of isometric exercise in facilitating recovery remains limited. Previous studies have suggested that isometric muscle contractions may induce analgesic effects and increase pressure pain thresholds in musculoskeletal conditions. Whether these effects can improve recovery following exercise-induced muscle damage and DOMS has not been fully established.
The purpose of this randomized controlled trial was to investigate the effects of an isometric exercise program on recovery following experimentally induced DOMS in healthy adults. DOMS was induced using a standardized drop-jump protocol. Participants were randomly assigned to either an isometric exercise group or a control group. Outcome assessments were performed before DOMS induction, immediately after exercise, and during follow-up evaluations on Days 1, 3, and 5.
The findings of this study may contribute to the understanding of the role of isometric exercise as a simple, low-cost, and clinically applicable recovery strategy following exercise-induced muscle soreness.

Experimentell: Isometric Exercise Group
Participants in this group underwent a standardized protocol to induce delayed onset muscle soreness (DOMS) and subsequently performed a structured quadriceps isometric exercise program during the recovery period.
|
Participants performed a structured quadriceps isometric exercise program following experimentally induced delayed onset muscle soreness.
The exercise protocol was applied according to the study protocol throughout the recovery period.

Sham Comparator: Sham Exercise Group
Participants performed a sham exercise protocol following experimentally induced delayed onset muscle soreness.
The sham intervention was designed to mimic the attention and participation associated with the experimental intervention without providing the intended therapeutic effect.

Pressure Pain Threshold
Tidsram: Baseline, immediately after exercise, Day 1, Day 3, and Day 5 following DOMS induction.
|
Pressure pain threshold measured using a digital pressure algometer following experimentally induced delayed onset muscle soreness (DOMS).
|
Baseline, immediately after exercise, Day 1, Day 3, and Day 5 following DOMS induction.
|
|
Pain Intensity
Tidsram: Baseline, immediately after exercise, Day 1, Day 3, and Day 5 following DOMS induction.
|
Pain intensity will be assessed using the Visual Analog Scale (VAS).
The VAS consists of a 10-cm horizontal line ranging from 0 (no pain) to 10 (worst imaginable pain).
Participants will indicate their perceived pain intensity by marking a point on the line.
Higher scores indicate greater pain intensity.
