Can muscular hypertrophy be a bad thing?
Most of the time, muscle hypertrophy is a good thing; it signals that your muscles are growing normally or responding normally to resistance-training exercise. Occasionally, hypertrophy can be harmful, especially in diseases of the cardiac muscle tissue.
Which disease is a result of hypertrophy?
Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle becomes abnormally thick (hypertrophied). The thickened heart muscle can make it harder for the heart to pump blood.
Can a shoulder injury cause deltoid muscle atrophy?
A shoulder injury resulting in non-use of the shoulder will result in atrophy. Likewise, conditions that limit movement can also cause deltoid atrophy. In these situations, strength training can help to correct the problem. The axillary nerve is in your shoulder and helps to control the deltoid muscle.
What happens when you strain the deltoid muscle?
This can lead to discomfort in the area of the deltoid muscle with associated swelling and loss of function. A forced eccentric contraction of the shoulder (lengthening of the muscle belly while contracting), can lead to strain of the deltoid muscle (ie: doing a “negative “while weight lifting).
What are the grades of deltoid muscle tears?
Deltoid strains are classified in three grades. If you have a grade one strain, you can use your arm normally, but will have some tightness or soreness in your shoulder. Your shoulder may be slightly swollen. Grade two strains are partial deltoid muscle tears.
What causes numbness and weakness in deltoid muscle?
The axillary nerve is in your shoulder and helps to control the deltoid muscle. It can be damaged due to a direct injury, pressure, or inflammation and can result in axillary nerve dysfunction, whose symptoms include deltoid atrophy, numbness, and weakness.
