You tried a new class, pushed harder on a run or returned to the gym after a break. The next day felt fine, but forty-eight hours later climbing the stairs is a challenge. Muscle soreness after exercise is a normal part of training, and understanding it helps you recover sensibly and tell the difference between ordinary aches and genuine injury.
Why Soreness Is Delayed
The stiffness that peaks one to three days after activity is known as delayed onset muscle soreness, often shortened to DOMS. It is thought to result from tiny disruptions in muscle fibres and the surrounding connective tissue, followed by an inflammatory repair process. Contrary to a popular myth, lactic acid is not to blame; it clears from the muscles within an hour or so of finishing.
What Makes It Worse
DOMS is most likely when you:
- Try a movement or sport your body is not used to
- Increase intensity, distance or weight too quickly
- Perform lots of eccentric work, where muscles lengthen under load, such as running downhill or lowering weights slowly
- Return to training after time off
The good news is that the body adapts quickly. Repeating a similar session a week later usually causes far less soreness, a phenomenon known as the repeated bout effect.
Recovery Strategies That Help
Keep moving gently. Light walking, easy cycling or swimming increases blood flow and often reduces stiffness more than complete rest.
Sleep well. Much of the body’s repair work happens during deep sleep, so a regular bedtime supports recovery.
Eat and drink sensibly. Adequate protein spread across the day provides building blocks for muscle repair, while fluids and a balanced diet support overall recovery.
Use warmth. A warm bath or heat pack can make tight muscles feel more comfortable. Some athletes prefer cool water immersion; evidence for both is mixed, so choose what feels best.
Massage and soft tissue work. Studies suggest massage may modestly reduce perceived soreness. A 출장마사지 session at home after a demanding weekend of sport can be a relaxing way to ease heavy legs, though it supports recovery rather than speeding up tissue healing dramatically.
Preventing Excessive Soreness
Progress gradually, increasing training load by small steps each week. Include a proper warm-up and ease into new exercises with lighter loads. Mild soreness is not a sign of a better workout, so there is no need to chase it.
Soreness or Injury?
Normal DOMS feels like a dull, widespread ache that improves with gentle movement and fades within about five days. Sharp, localised pain, pain during a specific movement, swelling, bruising or an inability to bear weight suggest a strain or other injury that needs rest and assessment.
When to See a Doctor
Seek urgent medical attention if extreme muscle pain is accompanied by marked weakness, significant swelling, or dark brown or cola-coloured urine, as this can indicate rhabdomyolysis, a serious condition affecting the kidneys. Also see a doctor if soreness does not improve after a week, or if a calf is hot, swollen and painful, which can suggest a blood clot; avoid massaging that area until it has been checked.
