What is a hallmark symptom of Delayed Onset Muscle Soreness (DOMS)?

  1. A bruise within 12 hours

  2. Pain that occurs 24-48 hours after a workout

  3. Immediate pain during exercise

  4. Tightness after warming up

The correct answer is: Pain that occurs 24-48 hours after a workout

Delayed Onset Muscle Soreness (DOMS) is characterized by muscle pain and stiffness that typically occurs after engaging in intense or unfamiliar exercise. The hallmark symptom of DOMS is indeed the pain that arises 24-48 hours after the workout. This delayed response is thought to result from microtrauma to muscle fibers during exercise, particularly when involving eccentric movements or increased intensity. The timing of this soreness is essential for identifying DOMS as it distinguishes it from other types of exercise-related discomfort, such as acute muscle pain that may occur during or immediately after a workout. This understanding is crucial for personal trainers when creating workout programs and managing clients' expectations regarding recovery and soreness. Other symptoms of DOMS may include reduced range of motion and swelling in the affected muscles, but the delayed onset is a key aspect that supports the diagnosis. Recognizing this pattern allows personal trainers to provide appropriate guidance on recovery strategies and help clients understand the normal response of their bodies to exercise, ultimately promoting adherence to training programs.
