11.3: Health Related Components of Physical Fitness

  • Page ID
    11766
  • In many studies related to physical fitness and health, researchers have focused on exercise, as well as on the more broadly defined concept of physical activity. Physical activity is defined by the World Health Organization as any bodily movement produced by skeletal muscles that requires energy expenditure, while exercise is a form of physical activity that is planned, structured, repetitive, and performed with the goal of improving health or fitness. So, although all exercise is physical activity, not all physical activity is exercise. Although physical activity and exercise are defined concepts, the ultimate focus of the health related components of physical fitness is to provide a framework for components that are necessary for good health. They are cardiorespiratory (CR) endurance (also called aerobic endurance), flexibility, muscular strength, muscular endurance, and body composition.

    Cardiorespiratory Endurance

    • Aerobic endurance: The ability of the heart, blood vessels, and lungs to work together to accomplish three goals:
      1. deliver oxygen to body tissues
      2. deliver nutrients
      3. remove waste products.

    Intensity

    The Guidelines for adults focus on two levels of intensity: moderate-intensity activity and vigorous–intensity activity. To meet the Guidelines, adults can do either moderate-intensity or vigorous-intensity aerobic activities, or a combination of both. It takes less time to get the same benefit from vigorous-intensity activities as from moderate-intensity activities. A general rule of thumb is that 2 minutes of moderate-intensity activity counts the same as 1 minute of vigorous-intensity activity. For example, 30 minutes of moderate-intensity activity a week is roughly the same as 15 minutes of vigorous-intensity activity. A person doing moderate-intensity aerobic activity can talk, but not sing, during the activity. A person doing vigorous intensity activity cannot say more than a few words without pausing for a breath.

    Muscular Strength and Endurance

    • Muscular strength: The ability of muscles to exert maximal effort.
    • Muscular endurance: The ability of muscles to exert submaximal effort repetitively (contract over and over again or hold a contraction for a long time).

    These kind of activities, which includes resistance training and lifting weights, causes the body's muscles to work or hold against an applied force or weight. These activities often involve relatively heavy objects, such as weights, which are lifted multiple times to train various muscle groups. Muscle-strengthening activity can also be done by using elastic bands or body weight for resistance (climbing a tree or doing push-ups, for example).

    根据独立健康慈善金基金的分析,到2021年,医疗预算将持续缩减大概8亿欧元(超过10亿美金),尤其是在性健康和性传染病方面的缩减。

    • Intensity, or how much weight or force is used relative to how much a person is able to lift;
    • Frequency, or how often a person does muscle strengthening activity; and
    • Repetitions, or how many times a person lifts a weight (analogous to duration for aerobic activity). Repetitions play a key role in determining if an activity is improving muscular strength or endurance. Low repetitions with more weight will focus more on muscular strength, while high repetitions with less weight will focus more on muscular endurance. The effects of muscle-strengthening activity are limited to the muscles doing the work. It's important to work all the major muscle groups of the body: the legs, hips, back, abdomen, chest, shoulders, and arms.

    While the S&P 500 is on track to conclude another stellar year of gains, those who sought to beat the index are poised to finish with a more dubious distinction. According to Lipper, 85% of all active stock mutual fund managers had been trailing their benchmarks through the end of November. In a typical year, there are nearly twice as many managers outperforming, with only around two thirds of funds struggling to catch up. Lipper says this is the worst year for active managers relative to the market in three decades.

    Shapley made early theoretical inroads into the subject, using game theory to analyze different matching methods in the 1950s and 1960s. Together with US economist David Gale, he developed a mathematical formula for how 10 men and 10 women could be coupled in a way so that no one would benefit from trading partners. While that may have had little impact on marriages and divorces, the algorithm they developed has been used to better understand many different markets.
