Provide as complete a definition of fitness as possible. performance-related components of physical fitness are deemed skills not essential to the general population, such as speed. The ability of an individual to go about their day to day life with vigor and alertness, without becoming 7. I argued that separation of components into health- fatigued and retaining ample energy to pursue leisure activities and react in case of an emergency. related and performance-related may not be an ideal model. Give one of my arguments on this topic. 3. The question “are you fit?” should really only be correctly answered by the counter- question “fit for All components of fitness contribute to the range of abilities by the body, which in extreme situations (such what?” Explain what I mean by this statement. as being fast enough to escape some hurtling danger) one’s health may indeed rely on, or simply improve the Different activities/livelihoods require different levels quality of wellness of life in one’s pursuits and capacity. of the components of fitness in their accomplishment, such as specialization in athletes.

Most research experts recommend working out 3-5 14. “Correlation is not causation”. Explain the meaning of days per week to be in optimal health, although this statement with respect to research into human ‘optimal health’ is often defined as the absence of fitness and wellness. disease and many not take into account the amount of exercise needed to be ‘fit’ for different pursuits, such as Correlation suggests a mutual relationship between two those who want to pursue hiking. Any small amount of variables, whereas causation suggests the nature of one activity is better than none, and after a while the peak variable to be a result of the behaviour of the other. effects of exercise start leveling off with the amount With respect to human fitness and wellness, one can done. In truth the amount, intensity, and frequency of determine a direct causation between smoking and lung exercise varies from person to person, and you should problems, but only a correlation can be drawn between try to push yourself past ‘comfortable exercise’ in all regular exercise and overall health – which may be areas you wish to improve. It is possible to “overdo” attributed to a number of things in the regularly active exercise, however, and overtraining can reduce the population (who, being physically active, are possible body’s immune system and lead to fatigue and illness. less likely to smoke which causes health issues) that the non-active population may differ on. 11. Explain the “open window” theory. 15. Discuss the process you would adopt to change a Open window – the period of time after bouts of personal behaviour. extreme exercise where the activity of natural killer T- cells is reduced. I would select one target behaviour to change, and focus on that; setting a precise goal I could meet before 12.

Make a processes and behaviours within and between commitment. Review your goals frequently to assess individuals. However it can be advantageous in their attainability and set new goals once you’ve circumstances such as monitoring VO2 max for an achieved old goals. athlete between different forms of exercise in a controlled room/time frame. 17. What does SMART goal setting mean? Epidemiological studies compare the health of Specific (set goals that are specific and definable in their populations as they present themselves without any attributes) manipulation to observe correlation in physical activity and health. This is advantageous in observing trends for large portions of the population and developing Measurable (set goals that can be measured toward their achievement) overarching hypotheses/theories on fitness. However it can be disadvantageous when correlation is mistaken for causation, or when one accepts an epidemiological study Acceptable (set goals that you will feel good about doing) without examining whether they fall in the studies demographics. Realistic (set goals that are realistic that you have the capacity to accomplish) 13. What criteria should you apply to evaluate whether an epidemiological study is valid? Timely (have deadlines, set short and long term goals 1. The association between exercise and health is repeatable and create new goals when the old ones are achieved.) 2. The association between exercise and health is logical Chapter 2: Basic Principles of Physiologic Conditioning 3. The association between exercise and health is strong 1. Distinguish between physical activity and exercise. 4. Other obvious factors are shown not to be the cause of association Physical activity – any level of activity above resting Frequency – 3 times per week level, such as going for a walk or gardening Intensity – Swimming at a pace between 60-90% of Exercise – A subset of physical activity that is planned, maximum heart rate FOR SWIMMING. Maximum heart structured, and repetitive, such as swimming for 30 rate: 205 – 45 = 160 bpm. Target heart rate: 160 *.7 = minutes 3 times per week. 112, 160 *.9 = 144  between 112 – 144 bpm. 2. Describe the four principles of physiologic conditioning.

Explain the difference between the maximal heart rate and the heart rate reserve methods for determining Specificity Principle – when exercised the body exercise intensity. undergoes adaptations specific to the body systems being exercised. The maximal heart rate method only focuses on the percentage of maximal heart rate used, which is only a Reversibility Principle – once one reaches a level of part of looking at one’s aerobic capacity. The heart rate fitness one must continue to exercise to maintain that reserve method more accurately reflects the percentage level. use of one’s full aerobic capacity. Individual Differences Principle – individual 7. Define the Karvonen formula. characteristics such as genotype, age, and lifestyle, will affect how the adaptations to exercise are expressed. Maximum heart rate – resting heart rate = heart rate reserve. 3. In terms of aerobic training effects, what is the most important factor—training intensity, duration, or 8. What does RPE mean? frequency? Explain. Rate of Perceived Exertion. In terms of aerobic training effects, training intensity is the most important factor because training at low 9. Describe how to use the talk-test. intensity (for example; < 50%) has been shown to have next to no effect on fitness, whereas no lower threshold has been established for duration and frequency. During aerobic work (such as running) one should be able to sustain a conversation. If one can’t because one’s breathing is too laboured, the work being done is 4.

Be specific. sufficient aerobic intensity. Frequency – 5 times a week 10. Is it proper to apply an exercise prescription based on heart rate for running and cycling to swimming? Explain. Intensity – Running at a pace between 70-90% of maximum heart rate. Maximum heart rate: 220 – 28 = No, because swimming is not weight-bearing and occurs 192 bpm, Target heart rate range: 192 * .7 = 134, 192 * with the body in a lateral position where the vascular .9 = 173  between 125 – 173 bpm. column is lowered and the heart isn’t required to pump as hard to circulate the necessary blood.

In most voluntary everyday contractions, slow-twitch A muscle can produce the greatest amount of force motor units are recruited first. With increasing power when it is at resting length because the more proteins output, more fast-twitch motor units are recruited. that are pulled apart in the sliding-filament action, the Slow-twitch motor units have a lower power output but less overlap of protein filaments there is and therefore much greater endurance capabilities, whereas fast less force-generation is possible. On the other hand if twitch motor units have a higher power output but they get to short and overlap too much and again lower endurance capabilities. Slow-twitch motor units cannot produce optimal force. are also used to maintain upright posture (anti-gravity musculature). High-twitch motor units are used during 17.
