running leg musclesAnytime you place an overloading stimulus on the muscle tissue (such as when you lift heavy weights), you are going to create tiny little tears in the muscle that basically are breaking down the fibres. When given rest, the muscles will rebuild themselves, growing back stronger so they can be more resilient in the future.

Along with this muscle tearing process, one thing that is often experienced by individuals is a tendency to feel some muscular soreness about a day or so after heavy lifting or strong cardio workouts. While you do not need to feel muscular soreness in order for it to have been a good workout, the two are often experienced together.

Cyclists performed ten six-second bouts of all out effort, with 30-second rest periods while the researchers measured peak power output, total mechanical work, peak pedaling rate, and peak efficient torque. The same group of cyclists performed these workouts in the morning on one day, and in the evening on another day. They found that the short-term recovery patterns were slower in the evening than in the morning.

While the researchers offered no explanation; decreased muscle performance late in the day may have a lot to do with brain function. Each muscle is made up of millions of individual muscle fibers. Each muscle fiber is instructed to contract by a single nerve fiber that receives messages from the brain. Your brain is far more alert after sleeping and napping than after being active for many hours. Read the rest of this entry »
