subject: Recurrent Problem During Exercise [print this page] Involuntary tonic contraction of the muscle occurs, that is, muscle cramps, commonly known as "cramps." Occurred in the movement prevalent in the lower leg gastrocnemius muscle cramps, followed by flexor, flexor muscle and the flexor muscles.
Reason:
1. Cold stimulation. If the cold water, cold air and other environmental training, if for lack of exercise, high incidence of muscle cramps.
2 .Muscle disorder or injury. If too fast continuous contraction, the muscles relax enough from spasm, or movement, repeated micro-injury of muscles, causing the protective tonic contraction.
Performance: Muscle cramps, the local hardening, pain, fingers, toes involuntarily flexion, extension difficult.
Treatment:
1. Pull finger flexion (toe), so that hyperextension, so that the muscles are stretching and spasm spasm, and local massage, hot compress.
2. Leave the cold stimuli in the environment to drink salt water.
Prevention:
1. Strengthening exercises to improve the ability to adapt activities to prepare adequately before exercise, especially when exercising in cold environments, especially should pay attention to this point. Prone to spasm of the muscles, proper massage.
2. Keep warm in winter, winter swimming can not be inactive for too long in the water, swimming in summer as the water temperature is low, the swimming time not too long.
3. Summer sweat more, pay attention to drink salt water, add the loss of electrolytes.
4. Tired, not long strenuous exercise.
Second, exercise-induced syncope
After exercise in the movement or temporary loss of consciousness, known as exercise-induced syncope, sudden ischemia is caused by the brain, low levels prevalent in the training of young people.
Reason:
1. Reduced cardiac output.
Lack of exercise are usually a sudden large amount of exercise to participate in the exercise, the heart function can not keep up movement needs a time, plus usually a lack of training, lack of coordination, breath holding,
resulting in reduced flow of blood back.
2. Gravity shock. Such as the long standing motionless for a long time suddenly got up and squatting, running, and suddenly stop activities, can be returned by gravity to the blood flow reduction, and the formation of brain
ischemia.
Performance:
First by generalized weakness, dizziness, ringing in the ears, eyes black, pale and other prodromal symptoms, followed by loss of consciousness, suddenly fell to the ground, hand, foot cold, slow and weak pulse, blood pressure, breathing slowly, miosis and other symptoms.
Treatment:
With prodromal symptoms should be squatting or lying under a short break, you can avoid fainting. Have syncope should make it almost lying down, head low enough high, loosen the collar, keep warm, push the lower limbs
as concentric kneading massage. Wake pinch or acupuncture may refer to people, Baihui, springs, Hegu and other points, or smell of ammonia, and can be awake. If breathing has stopped, could be artificial respiration, then head to turn to the side, avoid blocking the throat mucus or vomit.
Prevention:
1. Adhere to exercise, enhance physical fitness.
2. Long standing, we should always turn lower limb activities, do not suddenly stand up after squatting for a long time to slowly stand up.
3. Do not sprint after the arrest does not move, to continue to jog and take a deep breath for a moment.
4. Chronic illness, the infirm, temporarily to participate in strenuous exercise.
