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.

    为了尝试遏制煤炭消耗量的增长,中国正在可再生能源和核能领域投入巨资,但尽管付出了这些努力,中国迄今为止依然是最大的温室气体排放国。中国每年因化石燃料燃烧和水泥生产排放100亿吨二氧化碳,几乎是美国的两倍,但美国的人均排放量依然远远高于中国。

    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).

    • 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.

    Market watchers were forced to digest the reality of negative 2.9% GDP for the first quarter of the year. All of a sudden, everyone’s forecasts seemed too rosy—or at least too smooth—compared to the lumpy reality. This led to a raft of second-guessing on the timing of the Fed’s eventual exit from its bond-buying stimulus program. We went from confidence to WTF? in a space of a few weeks, with all the asset class rotations and market corrections that come along with a fresh bout of uncertainty.
