At FitToFar we never stop insisting on the importance of good muscle toning work to “keep birthdays under control.” Now we also know, after having read the *study published in Phisiology.org, that the loss of muscle inherent to age and accentuated by inactivity is much more pronounced in the legs than in the arms.(1)
The graph shows the distribution of muscle mass according to the study carried out on 468 men and women between 18 and 88 years old. The line that represents the lower body has a much steeper decline than the one that represents the upper body.
The best remedy, and practically the only one, is regular physical activity , emphasizing intense sessions with high loads and somewhat contradicting the prescriptions of doctors who generally prescribe “walking and swimming.” If you start from a terrible physical condition, walking and swimming are enough to start, but otherwise more intense activity is needed for the stimulus to do anything significant to maintain muscle mass. Furthermore, if intense activities are not carried out, bone density decreases even more with age, a problem that is especially significant in women due to the hormonal decline of maturity.
