How Injury Begins

Amateur athlete is highly susceptible to injury because the muscles, tendons and ligaments are weak. Often the force applied to them is greater than their inherent strength. Several hours after training sessions is when muscle soreness is likely to set in. Soreness takes several hours to surface because the body must take steps to repair muscular damage. First is the trauma resulting inflammation. Second, fluid is leaked into gaps between muscle fibers to facilitate the healing process, creating an edema (swelling).

Since training thickens the muscles and makes them more resilient, the better condition the athlete is in, the less severe the soreness will be. Training thickens muscles, tendons and ligaments, making them more resilient. The musculature can sustain higher workloads without breaking down. Severe muscle tears occur more often in a beginning athlete due to the muscle being taxed so heavily that it loses its ability to relax and stretch.

The serious athlete, on the other hand, usually suffer fatigue-related injuries rather than the tearing of unconditioned structure.

Hypothalamus

The hypothalamus is a small area of the brain located in the section of the forebrain called the diencephalon. The hypothalamus is a neural and an endocrine organ. It is concerned with maintaining homeostasis- that is, keeping the body's internal environment constant. The hypothalamus is also essential in controlling behaviour and allowing appropriate responses to multiple incoming stimuli. It continually receives information from the central and peripheral nervous systems concerning temperature, pain, pleasure, feeding, hunger, body mass and metabolic status.

Pack yourself with more muscles

Muscle burn calories. For every 1kg of muscle you gain, you will burn
70-100 calories per day.

Therfore, when you are resting or sleeping, you are burning extra calories away.

With more muscles, you will get higher metabolism rate, isn't that good :) You will definitely look toned, healthy, and confident!
