Therapeutic Lifestyle Program Exercise for Life
Exercise for Life Topics: • Benefits of exercise • Body composition • Measuring progress • How to make exercise a part of your life
Exercise • Being physically active helps you feel good and helps you get more enjoyment out of life • Physical activity is one of the most important things you can do to enjoy a longer, healthier life
Why Exercise? • Prolongs life • Improves mood • Achieves metabolic balance • Promotes sustainable weight loss • Strengthens heart and blood vessels • Increases bone density • Decreases risk for chronic conditions
Aging, Health Risks and Cumulative Disability • “Persons with lower health risks tend to live longer than those with higher health risks. . .” • “Not only do persons with better health habits survive longer, but in such persons, disability is postponed and compressed into fewer years at the end of life.” N Eng J Med 1998;338:1035-41
Decreases Risk of Common Chronic Conditions • Heart disease • Hypertension • Insulin resistance and diabetes • Arthritis • Depression • Cancer • Overweight/obesity • Osteoporosis EXERCISE RISK
Strengthens Heart • Heart is a muscular pump • Beats 100,000 times per day • Beats 35 million times per year • Promotes oxygenation of tissues and delivery of nutrients • Promotes removal of waste products
Strengthens Bones • Weight bearing exercise and resistance training will strengthen bones
Weight Management • Burns excess calories • Increases lean body mass (LBM) • Strengthens this muscle mass • Increases basal metabolic rate (BMR)
Basal Metabolic Rate • Rate at which your body uses calories at rest • Lean body mass influences BMR • People with higher % of lean muscle mass burn more calories
Metabolic Balance • Muscles use blood sugar for fuel • Exercise helps transport blood sugar into body cells • Keeping blood sugar and insulin in healthy range EXERCISE INSULIN BLOOD SUGAR Metabolic Balance
Body Composition • 3 Compartments • Lean Body Mass • Body Fat • Water Fat Lean Mass Water
Effects of Aging on Body Composition • Body fat increases • Lean muscle mass decreases(referred to as sarcopenia) BODY FAT LEAN MASS 20 30 40 50 60 70 80 90
Effects of Exercise on Body Composition • Body fat decreases • Lean muscle mass increases LEAN MASS BODY FAT EXERCISE------------->
Measuring Progress • Weight for Height • Body Mass Index • Waist/Hip or Waist Circumference • Bioelectric Impedance
Weight for Height • Wide range of weights for given height • Doesn’t address body composition • Crude measurement
Body Mass Index (BMI) • BMI = Weight(in kg) Height2(in meters) • Tables of BMI values are readily available • A BMI of <25 = desirable 25 – 29.9 = overweight >30 = obese
Bioelectric Impedance • Measures body composition • Lean muscle mass – predicts BMR • Body fat % • Body water – hydration status

Fitness – 3 Components • Aerobic – cardiovascular • Strength • Flexibility AEROBIC STRENGTH FLEXIBILITY
Aerobic Exercise • Oxygen supply to muscle is constant • Exercise within target heart rate range • Walking, hiking, swimming, cycling, rowing, running
Aerobic Exercise • Great for metabolic balance • Uses fat and glucose for fuel • Tones cardiovascular system • 30 - 60 minutes most days of the week
Strength Training • The resistance in strength training: • Increases lean body mass • Improves basal metabolic rate • Key point to remember: • Exercise muscle until fatigued • Provide the calories and protein needed to build muscle
Strength Training – Frequency • If your goal is to: • Lose fat, 2 times per weekmaintain LBM • Increase LBM 3 – 4 times per week
Flexibility • Lose flexibility, agility with aging • Muscle fibers shorten • Joint connective tissue weakens
Stretching Improves Flexibility • Lengthens muscle fibers • Strengthens tendons and ligaments • Prevents injury • Mentally relaxing • Stretch 5 minutes after mild warm-up before exercise session and after
Stretching Properly • Go slow – gradually stretch muscles • Don’t bounce – this may cause tears • Don’t curve spine – keep back straight • Hold stretches for 5 – 30 seconds • Stretch for at least 5 minutes after exercising
Summary • Body composition more informative than weight for height • Lean muscle mass critical for long term health and fitness • Exercise helps improve body composition • 3 important types of exercise • Aerobic, strength, stretching
Healthy Lifestyle • Live your life as if your health depends on it…because it does!
Healthy Lifestyle • Add Life to your Years versus Years to your Life
