Strength Training – Lower Limb
The appropriate intensity for lower limb strengthening exercises can be prescribed based on:
A. One repetition maximum (1RM)* i.e the maximum weight that can be lifted once by a particular muscle group
B. Ten repetition maximum (10 RM) i.e the maximum weight that can be lifted 10 times by a particular muscle group
*Caution: Testing pulmonary rehabilitation patients for their 1 RM may not be advisable. There may be concerns regarding joints, ligaments and bone density in many of these patients.
Prescribing intensity based on repetition maximum
Although 1RM is used in the healthy population as a basis for strength training intensity a 1RM manoeuvre may be too stressful on joints and ligaments of deconditioned and elderly patients
More often 10 RM is used i.e a weight that can be lifted a maximum of 10 times. Such a weight will be lighter than that of a 1RM weight.
