All forms of human movement rely primarily on muscle contraction. Muscle contraction requires energy, which is mainly supplied by the breakdown of carbohydrates within muscle tissue.
In oxygen-rich conditions, such as during rest, carbohydrates in muscles are directly broken down into carbon dioxide and water, releasing substantial energy.
However, during intense physical activity, skeletal muscles demand substantial energy. Although respiration and blood circulation significantly increase at this time, they still cannot fully meet the oxygen requirements of muscle tissue, causing the muscles to enter a temporary state of oxygen deprivation. As a result, carbohydrates break down into lactic acid, releasing relatively less energy.
The accumulation of lactic acid within muscles stimulates nerve endings in muscle bundles, causing a sensation of soreness. This buildup also increases osmotic pressure within the muscles, leading to the absorption of excess water and resulting in localized swelling.
Individuals who exercise regularly enable their muscles to obtain sufficient oxygen during activity, resulting in less lactic acid produced from carbohydrate breakdown and thus minimal muscle soreness.
Relieving muscle soreness often involves stretching and lengthening the muscles. This may occur because stretching stimulates the muscle's Golgi tendon organs, triggering inhibitory impulses.From a central nervous system perspective, stretching muscles alters the excitability of corresponding neural centers. Through the negative stretch reflex, it blocks spasms caused by excessive muscle spindle excitation and improves local tissue ischemia resulting from spasms. This enhances muscle blood flow and promotes recovery of damaged tissues.Electromyography (EMG) also demonstrates that stretching sore muscles gradually reduces their electrical discharge, leading to a state of electrical rest. This indicates that static stretching can improve the excitability of sore muscles. Repeatedly stretching muscles immediately after exercise and before soreness develops yields more pronounced relief of muscle soreness.
How can this be prevented?
1. Post-exercise relaxation.After exercise, rest briefly on a foam or rattan mat. When lying flat, position your feet slightly higher than your head or at the same level. Never lie on damp ground. After resting, perform a headstand or wall-assisted handstand for 3–10 seconds, repeating several times to facilitate blood return from the lower limbs to the heart.Then shake out your limbs: begin by shaking and patting your thighs or upper arms, followed by your calves or forearms.Begin by shaking the limbs to relax the elbow and knee joints along with the muscle groups of the limbs. Commonly used acupressure points on the upper limbs include Bianli (BL11), Quchi (LI11), Shouwuli (LU5), and Biyuexu (LI11), which can relieve soreness, swelling, and pain in the arms and elbows, as well as post-exercise discomfort such as shoulder-arm pain and neck stiffness.For the lower limbs, commonly pressed points include Chengfu (ST17), Weiyang (BL39), Chengshan (BL57), Kunlun (BL60), and Zusanli (ST36). These help relieve pain in the lumbar, sacral, buttock, and thigh regions; cramping and pain in the legs and feet; stiffness in the waist and legs; neck stiffness; lower back pain; and soreness in the knees and shins. When kneading and tapping, begin with larger muscle groups before moving to smaller ones. After massaging one side, proceed to the other.For mutual full-body massage, focus primarily on the Shu points along the back, typically located 1.5 cun lateral to the spine. Massage and relaxation techniques should concentrate on areas 1.5 cun lateral to the spine, along with the Jianwaiyu, Jianjing points on the shoulders, and the Tianzong point near the scapula. This helps relieve back pain and neck stiffness. Combining these techniques yields excellent relaxation effects with rapid recovery. They also provide health benefits for the internal organs.
3. Exercise planning should be reasonable. After a period of training, the exercise intensity that previously caused muscle soreness will rarely trigger symptoms again. This effect is specific. For example, after training for a period of time, downhill exercise can reduce muscle soreness caused by downhill training.
4. Apply local warmth and topical medications. Soaking in warm water after exercise can reduce muscle soreness. Applying oils, ointments, or massage balms to affected areas may also alleviate pain.
5. Muscle stretching exercises can lessen soreness. Stretching accelerates muscle relaxation and counteracting muscle relief, aiding recovery of tense muscles. Such stretching routines also lay the groundwork for preventing exercise-related strains.
6. Perform adequate warm-up and cool-down routines. Thorough preparation and proper post-exercise activities help prevent or reduce muscle soreness.

Healthy weight loss primarily relies on exercise, and among all activities, skipping rope is arguably the most convenient. It requires minimal space and delivers noticeable results. Let's explore it together!
Skipping rope is simple to learn, space-efficient, and produces quick results. Women of all ages can adjust the intensity based on their physical condition.Practice shows that skipping rope is indeed effective for weight loss, particularly in reducing excess fat in the legs and buttocks. Simultaneously, it provides cardiovascular benefits. Key points for skipping rope weight loss: Perform 5-minute sessions daily, aiming for 5-6 sessions per day over 6 days a week. Gradually increase duration as you adapt. Consistent long-term practice will effectively reduce body weight.
Techniques:
Double-foot jump with bounce: After each rope pass, both feet bounce off the ground together.
Double-foot jump without bounce: Continuously jump over the rope without bouncing.
Single-leg jump: Alternate feet jumping, resembling running motion.
