You finish a workout and feel great. Then you get up the next morning and your exercised muscles feel sore. You find it hard to lift your arms and brush your teeth, or bend down to pick up a book. What has happened?
Scientists call this soreness 24 to 48 hours after your exercise “delayed onset (延迟发作) of muscle soreness”, or DOMS. It is caused by microscopic damage to muscle fibers, which releases chemicals. The chemicals irritate (刺激) nerve fibers and cause pain.
Muscle soreness is a good sign. It means that you have challenged your muscles and are getting stronger. Everyone experiences it, even the best athletes. But it can be avoided by using the right exercise methods. Here are some tips:
* Warm up before you work out. This is helpful to avoid muscle soreness, but more importantly to avoid injury. It starts circulation to the muscles and warms the muscles and tendons, getting them ready for exercise.
* Stretch after your workout. After exercising, make sure you stretch your muscles for 15 to 20 seconds before they cool down. They will be warm and elastic (弹性的) so they will stretch well.
* Don’t do too much too soon. Whether it’s jogging, running, whatever workout routine you are starting, just do half of the exercise volume the first week to introduce your muscles to the exercises.
If you are already feeling muscles soreness, here are some ways to help relieve it.
* Get a massage (按摩). Lightly massage the sore muscle and gradually increase the depth of the massage. It might be painful in the beginning but it will gradually ease the muscle soreness.
* Take a hot bath. Nothing beats a long soak in a hot bath for muscle soreness. The heat will increase circulation and provide a soothing (舒缓) effect.
* Flush your muscles. Run hot (as hot as you can bear) water over the sore muscles for two minutes and then immediately switch to cold water for 30 seconds. Repeat this process five times. This has the effect of opening and closing your blood vessels (血管). It will flush the acid (酸物质) from them and ease the soreness.
* Exercise gently. Go for a slow walk and breathe deeply. This helps reduce muscle soreness by increasing blood flow to the sore muscles.
