Physical fitness
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest. Before the industrial revolution, "fitness" was defined as the capacity to carry out the day’s activities without undue fatigue. However, with automation and changes in lifestyles "physical fitness" is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.
Sport in China
"This article is about sport in the People's Republic of China. For sport in the Republic of China, see Sports in Taiwan." Sport in China has been long associated to the martial arts. Today China (including mainland China, Hong Kong and Macau) consists of a variety of competitive sports. Traditional Chinese culture regards physical fitness as an important characteristic. China has its own national quadrennial multi-sport event similar to the Olympic Games called the National Games. According to the Chinese Basketball Association, there is a record number of around 300 million active basketball players in Asia.
United States Army Physical Fitness Test
The Army Physical Fitness Test (APFT) is designed to test the muscular strength, endurance, and cardiovascular respiratory fitness of soldiers in the Army. Soldiers are scored based on their performance in three events consisting of the push-up, sit-up, and a two-mile run, ranging from 0 to 100 points in each event. A minimum score of 60 in each event is required to pass the test. The soldier's overall score is the sum of the points from the three events. If a soldier passes all three events, the total may range from 180 to 300. Active component and reserve component soldiers on active duty are required to take a "record" (meaning for official records) APFT at least twice each calendar year.
United States Marine Corps Recruit Training
United States Marine Corps Recruit Training (commonly known as "boot camp") is a 13-week program of initial training that each recruit must successfully complete in order to serve in the United States Marine Corps. All enlisted individuals entering the Marine Corps, regardless of eventual active or reserve duty status, will undergo recruit training at one of the two Marine Corps Recruit Depots (MCRD): Parris Island, South Carolina or San Diego, California. Male recruits from the 8th, 9th and 12th recruiting districts (areas west of the Mississippi River except Louisiana and including parts of Illinois, Indiana, Wisconsin and Michigan) are sent to MCRD San Diego.
Physical Fitness Badge
The United States Army Physical Fitness Badge is awarded to soldiers who obtain a score of 270 or higher, with a score of 90 or above in each event, on the 300-point scale of the Army Physical Fitness Test. The badge was first authorized by the Secretary of the Army on June 25, 1986 and first issued on October 1, 1986. The Physical Fitness Badge is intended to recognize those who have excelled in physical fitness, which is considered an important aspect for military service. The only documentation required to award the Physical Fitness Badge is the record scorecard indicating the soldier has met the standard for the badge.
Bonnie Prudden
Bonnie Prudden (January 29, 1914 – December 11, 2011) was an American physical fitness pioneer, expert rock climber and mountaineer. Her report to Eisenhower on the unfitness of American children as compared with their European counterparts led to the formation of the President’s Council on Youth Fitness. Prudden authored 16 books on physical fitness and Myotherapy for all ages and abilities including two best sellers, "How to Keep" "Slender and Fit After Thirty" (1961) and "Pain Erasure: The Bonnie Prudden Way" (1980). She produced six exercise albums, hosted the first regular exercise spots on national television, had a syndicated television show, and wrote a column for "Sports Illustrated".
Canada Fitness Award Program
The Canada Fitness Award Program was a national fitness test and evaluation program operated by the Government of Canada department Health and Welfare Canada from 1970 to 1992. It was a successor to the Centennial Athletic Awards Program, and was replaced by the Active Living Challenge program. Millions of primary and secondary school children participated in the program. It was discontinued in part because it discouraged those it was intended to motivate. The program was developed by Sport and Recreation Canada, a division of Health and Welfare Canada. It was established as a national fitness program by the Government of Canada, and began operating in September 1970.

Physical exercise
Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, including increasing growth and development, preventing aging, strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, and also enjoyment. Frequent and regular physical exercise boosts the immune system and helps prevent certain "diseases of affluence" such as coronary heart disease, type 2 diabetes, and obesity. It may also help prevent stress and depression, increase quality of sleep and act as a non-pharmaceutical sleep aid to treat diseases such as insomnia, help promote or maintain positive self-esteem, improve mental health, maintain steady digestion and treat constipation and gas, regulate fertility health, and augment an individual's sex appeal or body image.

Human nutrition
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and health. Generally, people can survive up to 40 days without food, a period largely dependent on the amount of water consumed, stored body fat, muscle mass and genetic factors. Poor nutrition is a chronic problem often linked to poverty, a poor understanding of nutrition and dietary practices, and deficient sanitation and food security. Malnutrition and its consequences are large contributors to deaths and disabilities worldwide. Good nutrition helps children grow physically, promotes human biological development and helps in the eradication of poverty.
Exercise physiology
Exercise physiology is the physiology of physical exercise. It is the study of the acute responses and chronic adaptations to a wide range of exercise conditions. Exercise physiologists study the effect of exercise on pathology, and the mechanisms by which exercise can reduce or reverse disease progression. Humans have a high capacity to expend energy for many hours during sustained exertion. For example, one individual cycling at a speed of through over 50 consecutive days expended a total of 1,145 MJ (273,850 kcal; 273,850 dieter calories) with an average power output of 182.5 W.  Skeletal muscle burns 90 mg (0.5 mmol) of glucose each minute during continuous activity (such as when repetitively extending the human knee), generating ≈24 W of mechanical energy, and since muscle energy conversion is only 22–26% efficient, ≈76 W of heat energy.
Neurobiological effects of physical exercise
The are numerous and involve a wide range of interrelated effects on brain structure, brain function, and cognition. A large body of research in humans has demonstrated that consistent aerobic exercise (e.g., 30 minutes every day) induces persistent improvements in certain cognitive functions, healthy alterations in gene expression in the brain, and beneficial forms of neuroplasticity and behavioral plasticity; some of these long-term effects include: increased neuron growth, increased neurological activity (e.g., and BDNF signaling), improved stress coping, enhanced cognitive control of behavior, improved declarative, spatial, and working memory, and structural and functional improvements in brain structures and pathways associated with cognitive control and memory.
Reduced muscle mass, strength and performance in space
There is a growing research database which suggests that skeletal muscles, particularly postural muscles of the lower limb, undergo atrophy and structural and metabolic alterations during space flight. However, the relationships between in-flight exercise, muscle changes and performance are not well understood. Efforts should be made to try to understand the current status of in-flight and post-flight exercise performance capacity and what the goals/target areas for protection are with the current in flight exercise program. From the very beginning of the U.S. human space program, serious and reasonable concern has been expressed about exposure of humans to the microgravity of space due to the potential systemic effects on terrestrially-evolved life forms that are so suitably adapted to Earth gravity.
Epigenetics of physical exercise
Epigenetics of physical exercise is the study of epigenetic modifications resulting from physical exercise to the genome of cells. Epigenetic modifications are heritable alterations that are not due to changes in the sequence of nucleotides. Epigenetic modifications, such as histone modifications and DNA methylation, alter the accessibility to DNA and change chromatin structure, thereby regulating patterns of gene expression. Methylated histones can act as binding sites for certain transcription factors due to their bromodomains and chromodomains. Methylated histones can also prevent the binding of transcription factors by hiding the transcription factor's recognition site, which is usually found on the major groove of DNA.
