  2. Health Benefits of Exercise Increases HDL (the good cholesterol) Lowers resting heart rate Lowers blood pressure Helps prevent: - Heart disease - Stroke - Type 2 diabetes - Cancer - Osteoporosis • Helps manage stress • Improves quality of sleep • Helps decrease mild depression and anxiety • Enhances self-esteem • Helps manage weight • Helps maintain muscle mass • Improves overall feeling of well-being Hewlings/Medeiros Nutrition: Real People, Real Choices 1e 14.2 © 2009 Pearson Education, Upper Saddle River, NJ 07458 All Rights Reserved.

  3. Choosing the Right Exercise Should include aerobic exercise as well as stretching and strength training Realistic: Consider time and other constraints Schedule Be open-minded to new experience and adventure when available Hewlings/Medeiros Nutrition: Real People, Real Choices 1e © 2009 Pearson Education, Upper Saddle River, NJ 07458 All Rights Reserved. 14.3

  4. Exercise in Weight Management and Strength Training Weight Management Metabolic rate Importance of muscle mass Regulation of appetite Strength Training Not just one correct method ACSM recommends: Strength train 2–3 days per week with 1–3 sets of 8–10 exercises (conditioning all major muscle groups) Hewlings/Medeiros Nutrition: Real People, Real Choices 1e 14.4 © 2009 Pearson Education, Upper Saddle River, NJ 07458 All Rights Reserved.

  5. Sports Nutrition for Older Adults Older adults can benefit from the increased strength associated with exercise. Ed Whitlock recorded a 2:52:47 marathon time and became the oldest person to break a 3-hour marathon time at 69 years of age.

  7. Exercise Intensity Adjust according to goals Maximum heart rate = 220 – Age ACSM Recommendation • 3–5 days/week at moderate intensity • Moderate intensity: 55–70% • Workout time should inversely correspond with intensity. • Incorporate stretching Hewlings/Medeiros Nutrition: Real People, Real Choices 1e 14.11 © 2009 Pearson Education, Upper Saddle River, NJ 07458 All Rights Reserved.

  8. Determine Your Age-Predicted Target Heart Rate Range • Use the application tips on page 399 (estimating age-predicted heart rate) to complete this exercise. • 1. Determining age-predicted target heart rate: • 220 bpm – _________ = ________ bpm (age-predicted max heart rate, MHR) • (AGE) • 2. Calculating Heart Rate for Desired Exercise Intensity • Multiply age-predicted max heart rate by desired training intensities. • Moderate Intensity (50–70%) • High Intensity (70–85%) • ____________ bpm  ________ = ___________ bpm • (MHR) (low %) • ____________ bpm  ________ = ___________ bpm • (MHR) (high %) • 3. Heart Rate Target Training Range • ____________ bpm to ____________ bpm • (low %) (high %)

  9. Determine Your Age-Predicted Target Heart Rate RangeExample • Use the application tips on page 399 (estimating age-predicted heart rate) to complete this exercise. • 1. Determining age-predicted target heart rate: • 220 bpm – __20____ = ___200__ bpm (age-predicted max heart rate, MHR) • (AGE) • 2. Calculating Heart Rate for Desired Exercise Intensity • Multiply age-predicted max heart rate by desired training intensities • Moderate Intensity (50%–70%) • High Intensity (70%–85%) • __200_____ bpm  __.70___ = ___140___ bpm • (MHR) (low %) • __200_____ bpm  __.85___ = ___170___ bpm • (MHR) (high %) • 3. Heart Rate Target Training Range • ___140_____ bpm to ____170____ bpm • (low %) (high %)

  15. Energy Needs An athlete’s caloric needs can be far greater than those of a sedentary person. A healthy diet is still important. Important to choose nutrient-dense foods High consumption of empty calories can impair athletic performance. Consume small meals every three to four hours throughout the day to maintain adequate energy for exercise.

  16. Weight Gain (the Healthy Way) Requires planning Calculate realistic weight and calorie needs Add energy-dense foods Dried fruits, nuts, granola, etc. Desired goal is increased muscle mass, not fat Realistic weight gain (1/2 lb. per week) Lift weights; eat a little bit more than usual Hewlings/Medeiros Nutrition: Real People, Real Choices 1e 14.21 © 2009 Pearson Education, Upper Saddle River, NJ 07458 All Rights Reserved.
