The Ups and Downs of Exercise

Early in the decade, exergames, or interactive gaming systems, grew in popularity. A typical program was GoKids Boston, which met for two 90-minute sessions each week and used Dance Dance Revolution, LightSpace, Nintendo Wii, Cybex Trazer, Sportwall, and Xavix products. These programs were generally seen as positive, and a viable alternative to traditional fitness activities. But — and isn’t there always a but? — it was also recorded that “use of exergames by adolescents typically declines within a few weeks or months.”

At the same time, what amounted to an anti-exercise program emerged in some places. For instance, in Edgewater, Florida, a 48-family townhome community considered not only banning all outdoor play, but fining the residents $100 for each separate offense.

The common area had very little green space, and kids rode their bicycles and skateboards in the parking lot, so no more of that, and no games of tag, either. It’s hard not to see the grouchy residents’ side of things. There’s the noise, and nobody wants their car dinged up by a bike crashing into it.

Still, it makes a person wonder, couldn’t there be some kind of concession? Like, one morning a week, let’s all park on this one side of the lot, and allow the kids have their scooter rodeo or whatever? Would that be too much to ask? Maybe they worked it out. There does not seem to be any subsequent news.

Around the same time, Prince Edward County, Ontario, Canada, was working on becoming the first “come alive outside” community in North America. The object was “to teach young people the lost art of unstructured play at no cost to the municipality.” The prime movers were the Wentworth Landscaping Group, whose partial plans were described by journalist Nicole Kleinsteuber:

The landscaping group is working on developing a nature trail with fitness equipment near the soccer fields in Picton. The trail would start at Queen Elizabeth Public School, run across the street from PECI, along the top ridge of the Johnson Street soccer field and follow the track within the fairgrounds and the youth park.

Meanwhile, back in the lab

A meta study from researchers at the University of Missouri looked at “various animal models that simulate childhood obesity through inactivity.” This type of experiment uses a thing called the rodent wheel lock model, first allowing rats to have exercise, then shutting off the exercise wheels to see how the rodents’ organ systems are affected:

[S]tudies have shown that young, inactive rats have reduced insulin sensitivity, eat more and burn off fewer calories, and develop larger fat pads than animals who continue to exercise. Other studies show that fat cells multiply to a significantly greater extent in rats who aren’t allowed to run on their wheels…

Human studies have shown a similarity, in that inactive children strongly tend to remain inactive later in life, and that childhood inactivity “initiates the mechanisms that lead to the consequences of obesity seen in adults.”
