Learning Outcomes Describe the health benefits of being physically active. Distinguish between physical activity required for health, physical fitness, and performance. Identify the motivating factors for becoming physically fit, including the benefits, goals, and challenges to manage. Understand and be able to use the FITT principles for the health-related components of physical fitness. Design a training program that works for you, incorporating the key components of a personal physical fitness program. Summarize ways to prevent and treat common injuries related to physical activity. © 2015 Pearson Education, Inc.

Physical Activity for Health 26.2 percent of Americans are sedentary. Regular physical activity reduces the likelihood of coronary artery disease, high blood pressure, type 2 diabetes, obesity, and other chronic diseases. Physical activity refers to all body movements produced by the skeletal muscles, resulting in substantial increase in energy expenditure. Exercise refers to a planned, structured, and repetitive bodily movement done to improve or maintain components of physical fitness. © 2015 Pearson Education, Inc.

Physical Activity for Health If all Americans followed the 2008 Physical Activity Guidelines, it is estimated that the following deaths could be prevented: One third related to coronary heart disease One fourth related to stroke and osteoporosis One fifth related to colon cancer, high blood pressure, and type 2 diabetes One seventh related to breast cancer © 2015 Pearson Education, Inc.

Physical Activity for Fitness and Performance Physical fitness is the ability to perform regular moderate to vigorous levels of physical activity without excessive fatigue. © 2015 Pearson Education, Inc.

Health-Related Components of Physical Fitness Cardiorespiratory Fitness Aerobic ("with oxygen") is any exercise that requires oxygen to make energy for prolonged activity Aerobic capacity (VO2max) is the maximum volume of oxygen consumed by the muscles during exercise. © 2015 Pearson Education, Inc.

Health-Related Components of Physical Fitness (cont.) Muscular Strength Refers to the amount of force a muscle or group of muscles can generate in one contraction. To assess the strength of a particular muscle or muscle group, measure the amount of weight that can be moved one time and no more (one time repetition maximum, 1 RM). Muscular Endurance A muscle's ability to exert force repeatedly without fatiguing or the ability to sustain a muscular contraction for a length of time © 2015 Pearson Education, Inc.

Getting Motivated and Committing to Your Physical Fitness (cont.) Incorporating Physical Activity in Your Life Choose activities that you genuinely like. Choose activities that you are capable of doing. Start slow, plan enjoyable activities and progress to more strenuous or vigorous activities.

Principles of Fitness Training FITT Frequency The number of times per week you need to engage in particular exercises to achieve the desired level of fitness in a particular component Intensity Refers to how hard your workout must be to achieve desired level of physical fitness Time Refers to how many minutes or repetitions of an exercise are required at a specified intensity during any one session to attain the desired level of physical fitness Type Refers to what kind of exercises should be performed to improve the specific component of physical fitness © 2015 Pearson Education, Inc.

The FITT Principle for Cardiorespiratory Fitness ACSM recommends 3–5 days per week of moderate to vigorous, rhythmic, continuous activity at 64–95 percent of heart rate maximum be performed for 20–60 minutes at a time, depending on level of intensity. Twenty minutes is fine for vigorous-intensity workouts. Thirty minutes is fine for moderate-intensity workouts. The amount of aerobic exercise is at least 150 minutes per week for moderate intensity and 75 minutes for vigorous intensity. © 2015 Pearson Education, Inc.

The FITT Principle Applied to Cardiorespiratory Fitness, Muscular Strength and Endurance, and Flexibility © 2015 Pearson Education, Inc.

Target Heart Rate, Perceived Exertion, and The Talk Test Target heart rate can be determined by subtracting your age from 220 (males) or 226 (females). This is your maximum heart rate (MHR). Your target heart rate is somewhere between 70 and 90 percent of MHR. Borg's rating of perceived exertion (RPE) is another method of determining intensity. The talk test is the easiest but least scientific method of measuring cardiorespiratory exercise intensity. © 2015 Pearson Education, Inc.

Taking a Pulse © 2015 Pearson Education, Inc.

The FITT Principle for Muscular Strength and Endurance Frequency is 2–4 days per week of exercises that train major muscle groups, using enough repetitions and sufficient resistance to improve muscular strength and endurance. Intensity is determined using greater than 60 percent of your 1 RM for muscular strength, and less than 60 percent of it for muscular endurance. © 2015 Pearson Education, Inc.

The FITT Principle for Muscular Strength and Endurance Sets and Repetitions To increase muscular strength you need higher intensity and fewer repetitions and sets. For muscular strength, use a resistance of more than 60 percent of your 1 RM performing 2–4 sets with 8–12 repetitions per set. For muscular endurance, use less than 50 percent of your 1 RM, 1–2 sets of 15–25 repetitions. Rest Periods Resting between exercises can reduce fatigue and help with performance and safety. © 2015 Pearson Education, Inc.

Methods of Providing Resistance © 2015 Pearson Education, Inc.

Specificity, Exercise Selection, and Exercise Order Specificity Principle Effects of resistance training must be specific to the muscles exercised. You must include exercises for all the major muscle groups. You must ensure that overload is sufficient. You must have a degree of tension in muscles that is greater than that which they are accustomed to. Exercise selection must be specific. © 2015 Pearson Education, Inc.

The FITT Principle for Flexibility Use static stretching that slowly and gradually lengthens a muscle or group of muscles. Train a minimum of 2–3 days, but daily training produces the most benefits. Perform and hold the static stretch (10–30 seconds) at the point of tension, or mild discomfort, but not pain. © 2015 Pearson Education, Inc.
