#DOMS

A growing body of research argues that pain after exercise is not a necessary sign of progress. While delayed onset muscle soreness (DOMS) often follows workouts, experts say it does not indicate better gains or optimal adaptation. This shift in thinking aligns with safer training practices and has clear implications for Thai athletes, students, and anyone pursuing healthier habits.

While gym culture has long linked effort with pain, researchers explain that discomfort can signal effort but is not a reliable measure of improvement. A leading voice from the University of Bath emphasizes that you may gain more with a touch of soreness, yet pain alone does not drive growth or health benefits. This nuanced view helps to separate effort from injury and to promote sustainable training patterns.

“Feel the burn” and “no pain, no gain” are common mantras in fitness circles, but new research is challenging the idea that muscle pain is a necessary marker of exercise progress. According to a recent feature published by The Guardian (theguardian.com), experts argue that while muscle discomfort—especially the delayed onset muscle soreness, or DOMS—often follows exercise, it is neither a prerequisite for gains nor always a sign of positive adaptation. This timely revelation aligns with growing global awareness around safe exercise practices and has direct implications for Thai fitness enthusiasts, athletes, and anyone embarking on a healthier lifestyle.

A new wave of medical research and expert consensus is dispelling age-old myths about muscle soreness following exercise and highlighting what it really means for health and fitness enthusiasts, including Thai readers exploring their own fitness journeys. Contrary to the popular adage “No pain, no gain,” the latest findings suggest that post-exercise soreness, known as delayed onset muscle soreness (DOMS), is neither a requirement for progress nor an indicator of workout success, challenging beliefs that have been glorified in both international pop culture and Thai fitness circles for decades (The Guardian).

New medical research and expert consensus debunk long-running myths about muscle soreness after exercise. For Thai readers, the message is clear: soreness is not required for progress, and pushing through pain can hinder gains. Contemporary science shows that delayed onset muscle soreness (DOMS) does not signal a successful workout or necessary adaptation.

DOMS typically emerges 12 to 24 hours after unfamiliar or strenuous activity, peaking between 24 and 72 hours, and then fading. The old belief that lactic acid buildup causes next-day soreness has been debunked. A clinical assistant professor at a leading US university notes that lactic acid is cleared within an hour after exercise and is not responsible for subsequent muscle ache. Instead, microtrauma in muscle fibers from new or intensified movements triggers a temporary inflammatory response that explains the discomfort.
