This is known as compartment syndrome which leads to greater death of the surrounding muscle tissue around the injury. [14] As the muscle dies this will cause pain to radiate from the affected area into the compartmentalized tissue. A loss of range of motion from swelling will also be seen in the affected limb.
Excess catecholamines, when released directly by nerves that stimulate cardiac muscle cells, have a toxic effect and can lead to decreased cardiac muscular function or "stunning". [ 11 ] [ 12 ] Further, this adrenaline surge triggers the arteries to tighten , thereby raising blood pressure and placing more stress on the heart, and may lead to ...
Overtraining occurs when a person exceeds their body's ability to recover from strenuous exercise. [1] Overtraining can be described as a point where a person may have a decrease in performance and plateauing as a result of failure to consistently perform at a certain level or training load; a load which exceeds their recovery capacity.

A lower resting heart rate or slower heartbeat will fill the ventricles/heart better and allow for more of a forceful contraction of blood out to the rest of the body, says Dr. Weinberg.
Rhabdomyolysis (shortened as rhabdo) is a condition in which damaged skeletal muscle breaks down rapidly, often due to high intensity exercise over a short period. [6] [4] [5] Symptoms may include muscle pains, weakness, vomiting, and confusion.
Example ultrasound of an athlete. Athlete's heart most often does not have any physical symptoms, although an indicator would be a consistently low resting heart rate.. Athletes with AHS often do not realize they have the condition unless they undergo specific medical tests, because athlete's heart is a normal, physiological adaptation of the body to the stresses of physical conditioning and ...
Myocardial contractility represents the innate ability of the heart muscle (cardiac muscle or myocardium) to contract.It is the maximum attainable value for the force of contraction of a given heart.
Hypertrophic cardiomyopathy (HCM, or HOCM when obstructive) is a condition in which muscle tissues of the heart become thickened without an obvious cause. [8] The parts of the heart most commonly affected are the interventricular septum and the ventricles. [10]
