Physical fitness is maintained by a range of physical activities. Human factors and social influences are important in starting and maintaining such activities. Social environments can influence motivation and persistence, through pressures towards social conformity.

ObesityEdit

Template:Essay-like Obesity is a physical marker of poor health, and puts undue strain on the body. In January, Centers for Disease Control and Prevention (CDC), officials revised their estimates on the number of Americans who die each year because of poor diet and physical inactivity. According to a correction in the January 19 issue of the Journal of the American Medical Association, "About 365,000 people died because of those causes [poor diet and inactivity] in 2000, up from about 300,000 in 1990" (CDC).

AdultEdit

Obesity has become a serious health risk throughout the developed world. An examination survey indicates that "An estimated 65 percent of US adults are either overweight or obese. This is an increase from 47 percent of adults' ages twenty to seventy-four years estimated to be overweight in the 1976 to 1980 survey and 56 percent of adults in the same age group estimated to be overweight in the 1988 to 1994 survey" (Shortt 1070). Furthermore, 40% of adults in the United States in 1997 reported engaging in no physical activity, while 59% do not engage in vigorous leisure-time physical activity. Although these percentages and occurrences of inactivity among older adults may vary by racial and ethnic group, and by gender, it's stated that inactivity appears, "From 47 percent among woman age 75 and older to 59 percent in older black males and 61 percent in older black females" (Hughes et al. 55).

ChildrenEdit

Nearly one in five children in the United States are overweight. Ogden et al., studied 3,958 children and adolescents between the ages of 2–19 from 2003–2004.[1] The study was a part of the NHANES which is the National Health and Nutrition Examination Survey. The results were astounding. It showed that 17.1% of the 3,958 children were overweight. Not only is one in five children overweight, but over 35% percent of children ages 6–19 are seriously overweight.[1] Ogden et al., had results showing 37.4% of this group was considered to be seriously overweight. Another age range where there are a high percentage of children who are overweight, are the range from 6–11. Ogden et al., was a study which was conducted in 2003–2004. The data collected was arranged into different age ranges. It showed that 18.8% of children ages 6–11 are overweight.[1] Research has shown that obesity in children has increased a tremendous amount from 1999 to 2004. Ogden et al., also had a few studies done prior to 2004. This study was done in 1999. The study showed that 28.2% of children from the ages of 2–19 were overweight. In 2004 that amount rose up to 33.6%. The age range that was the most affected was children from the ages of 6–11. The percentage rose an amazing 7.4% from 29.8% to 37.2%.[1]

Obesity can be responsible for lowering an individual's views on themselves as well as their self-respect. Sweeting et al., conducted a test on children ages 11–15.[2] 2,127 students were surveyed on who was obese, who needed to slim down, and who was becoming obese. Of these students, 9.6% of males and 10.5% of females were considered obese at age 11. At age 15 10.5% of males and 11.6% of females were obese. 3.5% of the total students surveyed needed to slim down and 4.5% are becoming obese. The test revealed that obesity has a great effect on changing moods and lowering of self-esteem.[2]

Inactivity is one of the biggest reasons for obesity in children. Berkey et al., conducted a study on 11,887 children from the ages of 10–15 to test whether or not an increase in a person's activity level would reduce a person's body fat.[3] A test done on girls concluded that an increase in physical activity brought their body mass index (BMI) down .11. The male test resulted in a .33 decrease in their BMI. An increase of inactivity showed an increase in BMI for girls by .02.[3] A way to improve this inactivity would be by changing a child's daily physical regime. Switching an overweight child's daily physical activity could help a child lose weight and get into better physical condition. Rodearmel et al., studied a couple of Latino families who had at least one child between the ages of 7–14.[4] This was done over a 6-month span. There were two groups that the children were put into. The first group was the "America on the Move" group and the other group was the "self monitor only" group. The America on the Move group had to walk an additional 2,000 steps per day from their baseline which was already measured through pedometers and to eliminate 100 kcal/day from their normal diet by replacing dietary sugar with no caloric sweetener. The self monitor group did not have to change their physical activity or their diet. This group only had to record their physical activity with pedometers. Both groups had results showing they had decreased their BMIs with the America on the Move group decreasing their BMI much more significantly.[4]

Reasons for inactivityEdit

Generally in the West and particularly in the U.S.A., only 26% of adults engage in vigorous leisure-time activity (which includes a sport or exercising three or more times per week. In an effort to increase adult involvedness and decrease the percentage of adult inactivity, the US Department of Health and Human Services has set a national health objective for 2010 that hopes to "Reduce the prevalence of no leisure time activity from more than 25 percent to 20 percent of US adults" (Berlin, Storti, and Brach 1137). Even though most Americans do not meet recommended levels of physical activity, it is never too late to start. Unfortunately, inactivity can contribute to a range of health related problems including: obesity, heart disease, metabolic syndrome, and other disorders. Researches have shown, "49 percent of heart disease in sedentary patients is due to lack of exercise" (Perkins, Whitehead, Steptoe 725) and the relative risk of metabolic syndrome was, "1.7 (95% CI 0.9–2.8) for lack of exercise, 1.5 (95% CI 1.1–2.1) for a positive family history and 2.0 (95% CI 1.2–3.4) in individuals with none or only an elementary school education versus university graduation" (Lee et al. 48).

Given the social and economic costs of low levels of physical activity there have been a number of public policy initiatives to raise the level, particularly focusing on children and adolescents. For example, United States government agencies, at both Federal and State levels, have initiated a number of programs which include encouraging workers to bike to work rather than to drive. The Fitness Portal, (http://www.fitness.gov), provides a range of tools, examples, and case studies of organization ideas. A few examples given by the Fitness Portal include: using the push mower, going for a walk, taking the stairs instead of an elevator, biking, running errands, visiting friends, cleaning out the garage or the attic, volunteering to become a coach or referee, signing up for a group exercise class, joining a softball league, or parking at the farthest end of the parking lot (http://www.fitness.gov). For children they suggest: taking a dog for a walk, starting up a kickball game, joining a sports team, going to the park, helping their parents with yard work, playing tag, riding their bike to school, walking to the store, seeing how many jumping jacks they can do, or racing a friend to the end of the block (http://www.fitness.gov).

Even though The Fitness Portal provides suggestions that will help a person become more active in daily living, the number of children who can be considered "a couch potato" is increasing day after day. No matter how hard one may try to reverse this, the prevalence of sedentary leisure activities for children is significant. Today video games and the internet are the preferred over physical activity. It has been found that "26 percent of children and adolescents in the United States spend more than four hours a day watching television, and they have become even more sedentary with access to computers and video games" (Damlo 1434). Along with, "62 percent of children nine to thirteen years of age do not participate in organized physical activities, and 23 percent do not participate in non-organized physical activities outside of school hours" (1434). Unfortunately, the sense of joy and achievement associated with developing skills and abilities through exercising, the challenges of friends, and beating personal records have been lost for many.

There may be many reasons why people may remain inactive. One major reason is due to laziness—the refusal to transport one's self from home to gym, and so there are identified correlations between readily available physically tasking activities and the levels of exercise among the people in close proximity to the activities. Individuals completed a Physical Activity Questionnaire and research showed "Over one third (34 percent) of female and 12 percent of male adolescents had no leisure physical activity during a one-week period. Self-efficacy was found to have the highest correlation to leisure physical activity among all selected determinants, while 'laziness' had the highest correlation among perceived barriers" (Analysis). Along with the questionnaire other research suggested that fitness groups and fitness programs positively altered the exercise behavior of families and youths.

InitiativesEdit

Wellness On WheelsEdit

The Wear Valley District Council along with its local Durham Dales Primary Care Trust in England developed an innovative scheme in an effort to combat the high levels of poor health and obesity in the area. They created a mobile gym with electronic fitness monitoring equipment, which is called "WOW" (Wellness on Wheels). This effort was to persuade as many people as possible to enroll in regular workouts as part of a wider campaign in the district. Barry Nelson, a health editor for the Northern Echo, in an interview noted a high level of interest generated. The strategy was to take exercise to people's homes rather than waiting for them to use existing leisure facilities. Children and adults, who otherwise wouldn't have exercised, came out to exercise in the mobile gym. Clearly, from this instance, the availability and nearness of a fitness program in a community positively affected the fitness behavior of the residents. As history explains, twenty-three years ago, Mr. Hackleman was named benefits manager. At this time the county had just three health and fitness programs: blood pressure screenings performed by public health nurses, a tennis tournament and some aerobics classes. However, soon after the roster grew to include at least five preventive health screening programs, eight healthy lifestyle and wellness programs, twelve health improvement and risk reduction programs and five family-life education programs. Finally in 2005, Ms. Gibson documented a total of 3,382 participants in the county's health and fitness programs, or 2,283 individuals, representing 41% of the county's population.

Walking School BusEdit

Most research that defends the idea of fitness programs increasing exercise practices among children and adults stems out of San Diego. Heritage Elementary school implemented its first walking school bus. This initiative had students walking to their designated stops, but not waiting for the school bus. Rather, waiting for a train of people on foot to pick them up. This allowed the students to walk to school with their peers. Although it is not directly stated, a major reason children choose to walk is because they fall victim to mob mentality. Perhaps the phrase, "fall victim to mob mentality" has a negative connotation, but that is, in essence, what the children do. Because so many other students were walking, all joined in. In this instance, mob mentality and mass behavior have a positive influence on fitness behavior, and encourage the students to exercise. The opinion of children, teachers and volunteers has been in general very favorable toward the project. Research states, "91.4 percent of participating students stated they liked the initiative very much and 87.4 percent among them prefer to go to school by the Piedibus than by any other means. Teacher and volunteers outlined the social value of the project and the increase in physical activity as positive aspects of the project". The group environment of the walking bus provides comfort in exercising, which in turn leads children to exercise more often. Although not exactly identical to the "Forrest Gump phenomenon", this walking school bus exhibits the same results: "If I can do it, you can do it".

Video gamesEdit

Several video game companies have developed ways to mix the two spectrums of electronic and exercise. Dance Dance Revolution, perhaps the most well-known exercise game, had players earn points by dancing to a beat. Players earn more points for tapping dance pads on the dancing platform at precise times and in proper sequences, thereby incorporating physical exercise.

In 2006 Nintendo introduced the Wii, a next generation game console the features a motion sensitive controller. Many players have noticed the benefits of increased physical activity due to playing games on the Wii system, but that does not count as serious exercise.
