What is Delayed Onset Muscle Soreness?
When you change your training program, DOMS is common after a workout. When you are used to performing 15 repetitions, your muscles adapt to this style of training. If you suddenly switch to 8 repetitions with a heavier weight, you shock your muscles. Another way that your muscles can be shocked is if you have not done any exercise in 6 months, and you suddenly run a couple of miles. You may feel soreness all over your body the next morning. You may also notice muscle stiffness and weakness. These symptoms are a normal response to unusual exertion and are part of an adaptation process that leads to greater strength once the muscles recover. The soreness is usually the worst within the first 2 days following the activity and subsides over the next few days.
