Microtrauma is the general term given to small injuries to the body. Injury or bodily injury is Damage or Harm caused to the Structure or function of the Body caused by an outside agent or With regard to living things, a body is the integral physical material of an individual

Microtrauma can include the microtearing of muscle fibres, the sheath around the muscle and the connective tissue. Muscle (from Latin musculus, diminutive of mus "mouse" is contractile tissue of the body and is derived from the Tissue is a cellular organizational level intermediate between cells and a complete organism It can also include stress to the tendons, and to the bones (see Wolff's law). A tendon (or sinew) is a tough band of Fibrous connective tissue that usually connects Muscle to Bone and is capable of withstanding tension Bones are rigid organs that form part of the Endoskeleton of Vertebrates They function to move support and protect the various organs of the body produce It is unknown whether or not the ligaments adapt like this. In Anatomy, the term ligament is used to denote three different types of structures Fibrous tissue that connects Bones to other bones Increased lubrication in response to microtrauma to the bowels is a key factor to the beneficial effects of dietary fibre in increasing bowel robustness, though this is dissimilar to muscular hypertrophy. In Anatomy, the intestine is the segment of the alimentary canal extending from the Stomach to the Anus and in humans and other mammals consists Dietary fibers are the indigestible portion of plant foods that move food through the Digestive system, absorbing water and easing Defecation. Some believe microtrauma to the skin (compression, impact, abrasion) can also cause increases in a skin's thickness, as seen in running barefoot. If it does occur, it might be increased skin cell replication at sites under stress where cells rapidly slough off or undergo compression or abrasion.

Most microtrauma cause a low level of inflammation that cannot be seen or felt. Inflammation ( Latin, inflamatio, to set on fire is the complex biological response of vascular tissues to harmful stimuli such as Pathogens These injuries can arise in muscle, ligament, vertebrae, and discs, either singly or in combination. Repetitive microtrauma which are not allowed time to heal can result in the development of more serious conditions.

Back pain can develop gradually as a result of microtrauma brought about by repetitive activity over time. Back pain (also known " dorsalgia " is Pain felt in the back that usually originates from the Muscles Nerves Bones Because of the slow and progressive onset of this internal injury, the condition is often ignored until the symptoms become acute, often resulting in disabling injury. A symptom' (from Greek σύμπτωμα, "accident misfortune that which befalls" from συμπίπτω, "I befall" from In Medicine, an acute disease is a disease with either or both of a rapid onset a short course (as opposed to a chronic course Injury or bodily injury is Damage or Harm caused to the Structure or function of the Body caused by an outside agent or Acute back injuries can arise from stressful lifting techniques done without adequate recovery, especially when experimenting with more ballistic work, or work where the extensor spinae are stressed during spinal flexion when much of the load is commonly taken up by the slower to heal ligaments which may not adapt progressively to the stress. Weightlifting, also called Olympic weightlifting or Olympic-style weightlifting, is a sport in which participants attempt a maximum weight single lift of a barbell While the acute injury may seem to be caused by a single well-defined incident, it may have been preventable or lessened if not for the years of injury to the musculoskeletal support mechanism by repetitive microtrauma.

One possible example of beneficial microtrauma is in the form of microtears to the muscle fibres as a result of intensive exercise. This is done deliberately in weight training in order to stimulate the building of stronger muscles, ligaments, and tendons during the repair process. Weight training is a common type of Strength training for developing the strength and size of Skeletal muscles It uses the Force of gravity However, it is not known if this practice is as beneficial as originally thought. Sufficient time must be allowed for healing, to avoid overtraining. Overtraining occurs when the volume and intensity of an individual's Exercise exceeds their recovery capacity
