Analysis of the role and usage scenarios of handheld massage rollers for sore muscles

1. Role and function of massage rollers
Handheld massage rollers for sore muscles can promote blood circulation and metabolism. The rollers stimulate blood vessel dilation through rolling pressure, accelerate local blood flow, improve the delivery efficiency of oxygen and nutrients, and promote the discharge of metabolic wastes such as lactic acid and inflammatory factors. Roller massagers can reduce post-exercise edema, reduce the accumulation of inflammatory substances, and relieve delayed muscle soreness. Relieve muscle tension and fascia adhesion. Through continuous pressure and rolling, the transmission of muscle spasm signals is inhibited, excessive contraction of muscle fibers is reduced, and stiffness is relieved. Compared with traditional manual massage, rollers can apply deeper pressure through the principle of leverage, accurately act on muscle pain points, relieve deep pain, and improve exercise recovery efficiency.

2. Actual application scenarios and effects
After high-intensity training: Rolling massage of lower limb muscles (such as quadriceps and gastrocnemius) can reduce the probability of DOMS and reduce the intensity of soreness the next day.
Endurance exercise recovery: Use rollers to relax the deep fascia of the legs after mountain climbing, significantly improve soreness and joint flexibility.
People who sit for long periods of time: Rolling the upper back (trapezius and rhomboids) can relieve stiffness in the shoulders and neck and improve rounded shoulders and hunchbacks.
Muscle imbalance adjustment: Roll on tight muscle groups such as the iliopsoas and pectoralis minor, and use stretching movements to correct posture problems.
