In children with type IV, joint ROM and muscle strength decreased, especially in the LEs.
The study found that back muscle strength decreased significantly in the non-exercising group, but was maintained in the twins who exercised.
GH deficiency in adults is associated with fatigue, decreased energy, depressed mood, decreased muscle strength, decreased muscle mass, thin and dry skin, increased adipose tissue, and decreased bone density.
Consequently, upper extremity muscle strength decreases less rapidly than lower extremity muscle strength.
Respiratory muscle strength decreases with age and much more so in men than in women (Table 6).
Respiratory muscle strength decreases with age and can impair effective cough, which is important for airway clearance.
It is well documented in the literature that trunk muscle strength decreases in older adults [ 3, 5, 20].
Minzer et al. (2005) found that 1 month after TKA, quadriceps muscle strength decreased by 62% relative to the preoperative level.
In comparison with other injury models such as the myotoxic and contusion injury models, muscle strength decreased for 2 7 days after the injury, and recovered after > 14 days [ 26, 30].
12 If an elderly person becomes ill with pneumonia, and therefore has increased metabolic demands for oxygen in the setting of decreased respiratory muscle strength, decreased cellular energy reserve, and decreased overall muscle function, he or she may not be able to meet those demands.
