Evaluation of factors of senior fragility of the clients of third age at the Faculty of Physical Culture, Palacky University, Olomouc

Bone strength is conditional upon the quality of the metabolism of bone tissue, is linked to bone density and bone (Kalvach Z, 2004; Osteoporosis Prevention, Diagnosis, and Therapy, 2000). In the muscle component there is shrinkage in the volume of muscles, a loss of muscle strength, endurance, elasticity and speed of muscle contraction. It is precisely this wastage of muscle mass accompanied by a loss of muscle function (muscle strength or performance) as a consequence of ageing that is referred to as sarcopenia (Kalvach Z, 2004; Cruz-Jentoft A, 2010).
