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 ...
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 ...
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 ...
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.

A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [8] Symptoms may include headache, dizziness, difficulty with thinking and concentration, sleep disturbances, mood changes, a brief period of memory loss, brief loss of consciousness; problems with balance; nausea; blurred vision; and mood changes.
Brain injury can occur at the site of impact, but can also be at the opposite side of the skull due to a contrecoup effect (the impact to the head can cause the brain to move within the skull, causing the brain to impact the interior of the skull opposite the head-impact). While impact on the brain at the same site of injury to the skull is the ...
SIS is a potential complication from an athlete returning to a game before symptoms from a minor head injury have subsided. [4] Such symptoms include headache, cognitive difficulties, or visual changes. [1] The initial injury may be a concussion, or it may be another, more severe, type of head trauma, such as cerebral contusion. [5]
A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity ranging from mild traumatic brain injury (mTBI/concussion) to severe traumatic brain injury. [ 5 ]
