Children are the most naturally physically active human beings; reduced physical activity is a cardinal sign of childhood disease, and exercise testing provides mechanistic insights into health and disease that are often hidden when the child is at rest. The physical inactivity epidemic is leading to increased disease risk in children and, eventually, in adults in unprecedented ways. Cardiopulmonary exercise testing (CPET) biomarkers are used to assess disease severity, progress, and response to therapy across an expanding range of childhood diseases and conditions. There is mounting data that fitness in children tracks across the life span and may prove to be an early, modifiable indicator of cardiovascular disease risk later in life. Despite these factors, CPET has failed to fulfill its promise in child health research and clinical practice. A major barrier to more accurate and effective clinical use of CPET in children is that data analytics and testing protocols have failed to keep pace with enabling technologies and computing capacity. As a consequence, biomarkers of fitness and physical activity have yet to be widely incorporated into translational research and clinical practice in child health. In this review, the author re-examines some of the long-held assumptions that mold CPET in children. In particular, the author suggests that current testing strategies that rely predominantly on maximal exercise may, inadvertently, obfuscate novel and clinically useful insights that can be gleaned from more comprehensive data analytics. New pathways to discovery may emanate from the simple recognition that the physiological journey that human beings undertake in response to the challenge of exercise may be far more important than the elusive destination of maximal or peak effort.
Rest and relaxation. It's such a common expression that it has become a cliche. And although rest really can be relaxing, the pat phrase causes many men to overlook the fact that exercise can also be relaxing. It's true for most forms of physical activity as well as for specific relaxation exercises.

Few things are more stressful than illness. Many forms of exercise reduce stress directly, and by preventing bodily illness, exercise has extra benefits for the mind. Regular physical activity will lower your blood pressure, improve your cholesterol, and reduce your blood sugar. Exercise cuts the risk of heart attack, stroke, diabetes, colon and breast cancers, osteoporosis and fractures, obesity, depression, and even dementia (memory loss). Exercise slows the aging process, increases energy, and prolongs life.
Except during illness, you should exercise nearly every day. That doesn't necessarily mean hitting the gym or training for a marathon. But it does mean 30 to 40 minutes of moderate exercise such as walking or 15 to 20 minutes of vigorous exercise. More is even better, but the first steps provide the most benefit. Aim to walk at least two miles a day, or do the equivalent amount of another activity. You can do it all at once or in 10- to 15-minute chunks if that fits your schedule better. Add a little strength training and stretching two to three times a week, and you'll have an excellent, balanced program for health and stress reduction. And if you need more help with stress, consider autoregulation exercises involving deep breathing or muscular relaxation. Remember, too, that mental exercises are the time-honored ways to cut stress (see box).
As populations continue to extend life expectancy, a central concern is whether the added time comprises years of healthy life and promotes a high health-related quality of life into old age. PA is defined as any bodily movement produced by skeletal muscles that result in energy expenditure. PA encompasses exercise, sports, and physical activities performed as part of daily living, occupation, leisure, or active transportation. Exercise is a subcategory of PA that is planned, structured, and repetitive and that has as a final or intermediate objective for improvement or maintenance of physical fitness. Physical function is the capacity of an individual to perform the physical activities of daily living. Physical function reflects motor function and control, physical fitness, and habitual PA [1].
Improvements in mental health, emotional, psychological, and social well-being and cognitive function are also associated with regular PA. Despite these health benefits, PA levels amongst older adults remain below the recommended 150 min/week [9]. The crude global prevalence of physical inactivity is 21.4% [10]. This translates to one in every four to five adults being physically inactive, or with activity levels lower than the current recommendations from WHO [11]. Inactivity and aging increase the risk of chronic disease, and older people often have multiple chronic conditions (NFH, 2010). The exercise recommendations from WHO include both aerobic exercise and strength exercise as well as balance exercises to reduce the risk of falls. If older adults cannot follow the guidelines because of chronic conditions, they should be as active as their ability and conditions allow [12]. It is important to note that the recommended amount of PA is in addition to routine activities of daily living like self-care, cooking, and shopping, to mention a few.
Drawing on over a decade of research, Daniel Lieberman shows that, in fact, we evolved to be physically active but not to exercise. Offering insights from evolutionary biology and anthropology, he explains why and how exercise can promote health, debunks myths about sitting, speed, strength and endurance, and points the way towards how we can be more physically active in the modern world.
For more ways to make your rest days count, schedule a session with a personal trainer at The Rec to review your goals and strategies to achieve them. And be sure to take advantage of the MSK Clinic for a free 30-minute consultation with a physical therapist about any pains or strains you might be feeling.

Physical exercise is important for maintaining physical fitness and can contribute to maintaining a healthy weight, regulating the digestive system, building and maintaining healthy bone density, muscle strength, and joint mobility, promoting physiological well-being, reducing surgical risks, and strengthening the immune system. Some studies indicate that exercise may increase life expectancy and the overall quality of life.[17] People who participate in moderate to high levels of physical exercise have a lower mortality rate compared to individuals who by comparison are not physically active.[18] Moderate levels of exercise have been correlated with preventing aging by reducing inflammatory potential.[19] The majority of the benefits from exercise are achieved with around 3500 metabolic equivalent (MET) minutes per week, with diminishing returns at higher levels of activity.[20] For example, climbing stairs 10 minutes, vacuuming 15 minutes, gardening 20 minutes, running 20 minutes, and walking or bicycling for transportation 25 minutes on a daily basis would together achieve about 3000 MET minutes a week.[20] A lack of physical activity causes approximately 6% of the burden of disease from coronary heart disease, 7% of type 2 diabetes, 10% of breast cancer and 10% of colon cancer worldwide.[21] Overall, physical inactivity causes 9% of premature mortality worldwide.[21]
Most people can increase fitness by increasing physical activity levels.[22] Increases in muscle size from resistance training are primarily determined by diet and testosterone.[23] This genetic variation in improvement from training is one of the key physiological differences between elite athletes and the larger population.[24][25] There is evidence that exercising in middle age may lead to better physical ability later in life.[26]
Early motor skills and development is also related to physical activity and performance later in life. Children who are more proficient with motor skills early on are more inclined to be physically active, and thus tend to perform well in sports and have better fitness levels. Early motor proficiency has a positive correlation to childhood physical activity and fitness levels, while less proficiency in motor skills results in a more sedentary lifestyle.[27]
The type and intensity of physical activity performed may have an effect on a person's fitness level. There is some weak evidence that high-intensity interval training may improve a person's VO2 max slightly more than lower intensity endurance training.[28] However, unscientific fitness methods could lead to sports injuries.[29]
The beneficial effect of exercise on the cardiovascular system is well documented. There is a direct correlation between physical inactivity and cardiovascular disease, and physical inactivity is an independent risk factor for the development of coronary artery disease. Low levels of physical exercise increase the risk of cardiovascular diseases mortality.[30][31] e24fc04721
