Progressive overload is a method of strength training and hypertrophy training that advocates for the gradual increase of the stress placed upon the musculoskeletal and nervous system. [1] The principle of progressive overload suggests that the continual increase in the total workload during training sessions will stimulate muscle growth and ...
That is, an individual moves a certain load for some number of repetitions, rests, and repeats this for some number of sets, and the volume is the product of these numbers. For non-weightlifting exercises, the load may be replaced with intensity, the amount of work required to achieve the activity. Training volume is one of the most critical ...
The athlete may continue playing in the game after the second concussion, and may walk off the field without assistance, but symptoms quickly progress and the condition can rapidly worsen. [11] Neurological collapse can occur within a short period, [ 12 ] with rapid onset of dilating pupils , loss of eye movement, unconsciousness, and ...
Diffuse injury has more microscopic injury than macroscopic injury and is difficult to detect with CT and MRI, but its presence can be inferred when small bleeds are visible in the corpus callosum or the cerebral cortex. [34] MRI is more useful than CT for detecting characteristics of diffuse axonal injury in the subacute and chronic time ...
Crush syndrome progression (MC most common,# fracture, MODS multiple organ dysfunction syndrome, RTN renal tubular necrosis). Immediate untreated crush syndrome death is caused by severe head injury, torso injury with damaged abdominal organs, and asphyxia (excessive loss of oxygen).
Focal and diffuse brain injury are ways to classify brain injury: focal injury occurs in a specific location, while diffuse injury occurs over a more widespread area.It is common for both focal and diffuse damage to occur as a result of the same event; many traumatic brain injuries have aspects of both focal and diffuse injury.

The concept of allostatic load provides that "the neuroendocrine, cardiovascular, neuroenergetic, and emotional responses become persistently activated so that blood flow turbulences in the coronary and cerebral arteries, high blood pressure, atherogenesis, cognitive dysfunction, and depressed mood accelerate disease progression."
More than 50% of patients who suffer from a traumatic brain injury will develop psychiatric disturbances. [6] Although precise rates of anxiety after brain injury are unknown, a 30-year follow-up study of 60 patients found 8.3% of patients developed a panic disorder, 1.7% developed an anxiety disorder, and 8.3% developed a specific phobia.
