Medical Terminology: Learning Through Practice1st EditionPaula Manuel Bostwick 1,562 solutions any bodily movement produced by the contraction of skeletal muscles that results in a substantial increase in caloric requirements over resting energy expenditure Physical Activity a set of attributes or characteristics individuals have or achieve that relate to their ability to perform PA and activities of daily living Physical fitness Cardiorespiratory endurance:the ability of the circulatory and respiratory system to supply oxygen during sustained physical activity. Body composition:the relative amounts of muscle, fat, bone, and other vital parts of the body Muscular strength:the ability of muscle to exert force Muscular endurance:the ability of muscle to continue to perform without fatigue Flexibility:the range of motion available at a joint. These are all_______ related fitness components Health-related agility:the ability to change the position of the body in space with speed and accuracy coordination:the ability to use the senses, such as sight and hearing, together with body parts in performing tasks smoothly and accurately balance:the maintenance of equilibrium while stationary or moving power:the ability or rate at which one can perform work reaction time:the time elapsed between stimulation and the beginning of the reaction to it speed: the ability to perform a movement within a short period of time these are all ________ related fitness components skill several ______ related components can be important for achieving health goals and should be incorporated when designing exercise prescription programs with different populations. ex-power and balance activities with older adults skill Methods for estimating intensities include percentage of oxygen uptake reserve (VO2R), heart rate reserve (HRR), volume of oxygen consumed per minute (VO2), heart rate (HR), or metabolic equivalents (METs). METs are a useful, convenient, and among adults-light intensity _____ is defined as 1.6-2.9 METs, moderate as 3.0-5.9 METs, and vigorous as greater than 6.0 METs PA intensity estimations Because of age-related declines in maximal __________, when older and younger individuals work at the same MET level, the relative exercise intensity (e.g %VO2max) may be different. The older individual will be working at a greater relative %VO2max than their younger counterparts. But... physically active older adults may have aerobic capacities aerobic capacity Over 20 yr ago, people from ACSM, CDC, US surgeon general, and NIH came up with... Amount and intensity of PA needed to:improve health, lower susceptibility to disease (morbidity), decrease premature mortality. Documented dose-response relationships between PA and health i.e-some activity is better than none, and more activity, up to a point, is better than less Public Health Perspective for Current Recommendations All healthy adults aged 18-65 yr should participate in moderate intensity aerobic PA for a minimum of 30 min on 5 dwk-1 or vigorous intensity aerobic activity for a minimum of 20 min on 3 dwk^-1. Combinations of moderate and vigorous intensity can be performed to meet this recommendation. Moderate intensity aerobic activity can be accumulated to total the 30 min minimum by performing bouts each lasting greater than or equal to 10 min. Every adult should perform activities that maintain or increase muscular strength and endurance for a minimum of 2 d*wk^-1 Because of the dose-response relationship between PA and health, individuals who wish to further improve their fitness, reduce their risk for chronic diseases and disabilities, and/or prevent unhealthy weight gain may benefit by exceeding the minimum recommended amounts of PA. The ACSM-AHA Primary Physical Activity (PA) Recommendations Shortly after ACSM-AHA recommendations, the fed gov't convened an expert panel:"2008 Physical Activity Guidelines Advisory Committee found evidence of PA benefits for health as well as the presence of a dose-response relationship for many diseases and health conditions. 2 important conclusions that influenced the development of subsequent PA recommendations: 1. important health benefits can be obtained by performing a moderate amount of PA on most, if not all, days of the week. 2.Additional health benefits results from greater amounts of PA. Individuals who maintain a regular program of PA that is longer in duration, of greater intensity, or both are likely to derive greater benefit than those who engage in lesser amounts. These recommendations resulted in the 2008 Physical Activity Guidelines for Americans (first comprehensive guidelines related to PA published by the______) Federal Gov't Advisory Committee Updated conclusions from 2018 advisory committee findings: For those who are inactive, PA of any intensity (light, moderate, or vigorous) can provide health benefits. Health benefits can be experienced following just a single bout of moderate-to-vigorous PA (MVPA). Any bout of MVPA, regardless of duration can be included when quantifying daily or weekly volumes of PA intended to be counted toward meeting current recommendations. Notable change in the 2018 guidelines:the previous requirement that aerobic activities occur in bouts of more than 10 min in duration to elicit significant health benefits. 2018 physical activity guidelines Adults should move more and sit less throughout the day. Some physical activity is better than none. Adults who sit less and do any amount of moderate-to-vigorous physical activity gain some health benefits. For substantial health benefits, adults should do at least 150 minwk-1 to 300 minwk-1 of moderate intensity, or 75 min*wk-1 to of vigorous intensity aerobic physical activity, or an equivalent combination of moderate and vigorous intensity aerobic activity. Preferably, aerobic activity should be spread throughout the week. Additional health benefits are gained by engaging in physical activity beyond the equivalent of 300 min of moderate intensity physical activity a week. Adults should be also do muscle strengthening activities of moderate or greater intensity and that involve all major muscle groups on 2 or more d*wk-1, as these activities provide additional health benefits. The Primary Physical Activity Recommendations for Adults from the Physical Activity Guidelines for Americans, Second Edition (2018) Global pandemic-identified as one of 4 leading contributors to premature mortality. Globally, 31.1% of adults are this. In the US: 51.6% meet aerobic activity guidelines, 29.3% muscle strengthening guidelines, and 20.6% meet both the aerobic and muscle strengthening guidelines Physical inactivity American adults self-reported being _______ 4.7 hours/day. However, accelerometers reported 7.7-8.0 hours/day sedentary Prolonged periods of sitting or sedentary behavior are associated with deleterious health consequences (i.e increased risk for diabetes, cancer, and heart disease). -50% of an average person's waking day involves activities associated with prolonged sitting such as television viewing and computer. However, sedentary time was associated with a 30% lower relative risk for all-cause mortality among those with high levels of PA as compared with those with low levels PA. Sedentary Behavior and Health What is the minimum of physical activity needed each day to provide substantial health benefits?For substantial health benefits, adults should do at least 150 minutes (2 hours and 30 minutes) to 300 minutes (5 hours) a week of moderate-intensity, or 75 minutes (1 hour and 15 minutes) to 150 minutes (2 hours and 30 minutes) a week of vigorous-intensity aerobic physical activity, or an equivalent combination of ...
What is the minimum recommended duration for A session of physical activity to receive health benefits?Recommendations for Adults
Get at least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes per week of vigorous aerobic activity, or a combination of both, preferably spread throughout the week.
What is the recommended minimum weekly amount of physical activity?Each week adults need 150 minutes of moderate-intensity physical activity and 2 days of muscle strengthening activity, according to the current Physical Activity Guidelines for Americans. We know 150 minutes of physical activity each week sounds like a lot, but you don't have to do it all at once.
What is the recommended minimum number of days per week for participating in physical activity to develop cardiorespiratory endurance?All healthy adults aged 18–65 yr should participate in moderate intensity aerobic physical activity for a minimum of 30 min on five days per week, or vigorous intensity aerobic activity for a minimum of 20 min on three days per week.
