What effect does the muscle relaxation roller massager have on muscle relaxation?

1. Relieve muscle tension and fatigue

The muscle relaxation roller massager promotes local blood circulation and accelerates the removal of metabolic waste, especially lactic acid produced after exercise, by rolling and pressing muscles (such as erector spinae, trapezius, etc.). Studies have shown that using it for 15-20 minutes can significantly reduce muscle stiffness and increase skin temperature by 1-2°C, indicating that metabolic efficiency has improved.

The pressure stimulation of the roller activates the "gating theory" mechanism, that is, mechanical stimulation blocks the transmission of pain nerve signals, thereby reducing muscle soreness. The roller with heating function (temperature ≤45°C) has better effect, similar to the thermal radiation effect of moxibustion.

2. Loosen fascia adhesions

The lateral shear force of the roller can separate fibrotic tissue formed by chronic strain, similar to the traditional Chinese medicine muscle pulling technique. For the cord-like nodules of the latissimus dorsi and erector spinae, progressive rolling can improve the viscoelasticity of the fascia.

Regular use can increase the range of motion of joints (such as hips and knees), especially improve the tightness of hip flexors caused by long-term sitting, and avoid lumbar problems caused by muscle imbalance.

3. Promote blood circulation and recovery

The pressure of the roller can enhance the permeability of capillaries, improve the efficiency of blood oxygen supply, and improve microcirculation disorders such as coldness and numbness of the back.

Use within 30 minutes after exercise to reduce delayed muscle soreness (DOMS) and increase the clearance rate of blood lactate by 30%.

Regular rolling stimulation can reduce cortisol levels, relieve muscle tightness caused by anxiety, and enhance the relaxation effect with deep breathing.

4. Assist in correcting posture and preventing injuries

Rolling along both sides of the spine can stimulate the Huatuo Jiaji point group, regulate paraspinal muscle tension, and assist in correcting mild scoliosis or facet joint disorders.

Note: Severe spinal lesions require doctor's guidance to avoid aggravating injuries by self-operation.

Long-term use can improve muscle flexibility, reduce movement restrictions caused by fascia tension, and reduce the risk of strain.

5. Usage suggestions and precautions

Operation skills:

Roll each part 3-5 times, 20-30 seconds per set, total duration 10-20 minutes.

Apply force gradually from light to heavy, control the pain within 7 points (full score 10 points), and avoid violent operation.

Contraindications:

Patients with skin damage, severe osteoporosis, acute sprain or varicose veins are prohibited.

Pregnant women and patients with cardiovascular diseases need to consult a doctor.
