What Is the Difference between Muscle Fatigue and Weakness?

Muscle fatigue Muscles of the body withstand fatigue from work activities. The main manifestations are fatigue, weakened work ability, reduced work efficiency, distracted attention, slow operation speed, reduced coordination and flexibility of movement, increased incidence of errors and accidents, and decreased job satisfaction. There are obvious individual differences. Factors such as physical fitness, nutritional status, gender, age, work motivation and sense of responsibility all have significant effects on it. There are many theories trying to explain the mechanism of its generation. Among them, the central theory, the metabolite accumulation theory, and the energy depletion theory are more representative. The central theory believes that the inhibitory protection caused by the continued excitement of the relevant areas of the brain and the inhibition of the spread in the brain are the root causes of its occurrence. The theory of metabolite accumulation believes that its production is due to the continuous production and accumulation of metabolites (such as lactic acid) during work, causing the body to have a similar poisoning effect. The theory of energy exhaustion believes that long-term activities cause the exhaustion of energy substances in the body (such as muscle glycogen), which affects the energy supply of muscles, brains and various tissues and organs, and makes the body lose its ability to continue working. It is generally evaluated from work performance, subjective response, and physiological and biochemical aspects. Proper rest is the most important way to eliminate it. In addition to resting at rest, different muscles can also be rested alternately by constantly changing jobs. Scientifically designing work to keep the working environment and workload in an optimal state is also an important measure to reduce or delay its appearance. ^[1]

Muscle fatigue leads to a decline in working ability when the muscles work repeatedly. The occurrence of fatigue during exercise is related to the intensity of muscle work. Strong

Absolute ability of muscles to work and resist fatigue

Muscle fatigue sleep

Ensuring adequate sleep is a good way to eliminate fatigue and restore energy. During sleep, the excitatory process of the cerebral cortex is reduced, and the catabolism in the body is at the lowest level, while the anabolic process is relatively high, which is beneficial to the accumulation of energy in the body. Every day should ensure 8-9 hours of sleep, so that the body is completely relaxed.

Muscle fatigue massage

Passive massage and self-massage; Passive massage refers to the use of the masseur's hands on the body, which can expand and open the capillaries in the muscle, improve local blood circulation and nutrition, and accelerate waste in muscle movement Elimination of lactic acid, thereby achieving the effect of eliminating muscle fatigue.

Self-massage refers to cleverly rubbing the back with your own hands, patting the shoulders, lower limbs, etc. alternately, rubbing the legs, rubbing the chest and abdomen, standing and shaking the legs alternately, pushing the Yintang points, pressing the temples, and pressing the feet , Brush your scalp, hold your ears with both hands.

Muscle fatigue heat pack

Applying hot packs to sore local muscles can promote blood circulation, improve metabolism, and accelerate the relief and recovery of muscle soreness. It is the most effective way to eliminate muscle fatigue.

Muscle fatigue warm water bath

Warm water bath can accelerate blood circulation throughout the body and promote metabolism, which is beneficial to the transportation of nutrients and elimination of fatigue substances in the body, and accelerates the elimination of fatigue and the recovery of physical strength.

Muscle fatigue supplement

Eat more alkaline foods, such as fresh vegetables, fruits, soy products, dairy products, and animal livers that are rich in protein and vitamins. After these foods are digested and absorbed by the human body, they can quickly reduce blood acidity, neutralize and reach weak alkalinity, and are an important means to eliminate fatigue. Drink black wolfberry soaked in water every day.

Muscle fatigue drinking plain water

Warm boiled water can increase the activity of lactate dehydrogenase in the organs, which is conducive to quickly reducing the "fatigue factor" lactic acid accumulated in the muscles, thereby achieving the purpose of eliminating fatigue and refreshing the spirit.
