| خلاصه مقاله | Background and Aim: Physical inactivity is a risk factor for developing many chronic conditions that
impact functional mobility in older adults. Conditions like Heart disease, Hypertension, Type 2 diabetes,
Obesity, Osteoporosis…
Aerobic capacity, muscle mass and strength decline with age. The age related loss of strength is one the
most critical factors contributing to mobility disability. Up to one third of the age related decline in
aerobic capacity (VO2 max) can be reversed with prolonged (six months or more) aerobic training
leading to decrease in all-cause mortality and morbidity (even if started after age 75), also Resistance
exercise can result in 25 to %100 or more strength gains in older adults through muscle hypertrophy and
combined with adequate nutrition , prevent muscle wasting in institutionalized elderly, thus it is never too
late for patients to benefit from physical activity. Age should not limit training; however experts
recommend a more gradual approach in older patients.
Methods: An individual’s specific health history, risk factors, personal goals, & exercise preferences
will shape & detail the exercise prescription which should address the health-related physical fitness
components of cardiorespiratory (aerobic) fitness; muscular strength and endurance; flexibility and
neuromotor fitness. Components of the Exercise Prescription include FITT-PRO principle which are
frequency, intensity, time (duration), type & progression (advancement)
Results: Frequency recommended for aerobic exercise is about 3 to 5 days per week dependent upon
intensity, for Resistance & Flexibility training is 2 to 3 days per week and for Neuromotor exercise
training involving balance, agility, coordination, & gait is at least 2 to 3 days per week.
For inactive osteoporotic individuals , a supervised, non-strenuous, progressive resistive exercise
program can improve bone density which can be advanced to antigravity and strengthening
exercises.
Conclusion : The overall recommendations on physical activity state that adults over 18 years of age
must do at least 150 min/week of moderate intensity or 75 min/week of vigorous intensity aerobic
physical activity and muscle strengthening training 2 days per week focusing on all muscle groups .
Adults over 65 years are advised to follow the adult recommendations if possible or advised to be as
physically active as possible. Warm up and cool down periods consisting of 5 to 10 minutes of less
intense activity should be included to decrease the risk of hypotension , musculoskeletal and
cardiovascular complications.
Patients should be counseled to discontinue exercise and seek medical advice if they experience major
warning signs or symptoms (e.g., chest pain, palpitations or lightheadedness). |
