The word aerobics probably makes you think of a group fitness class where people perform coordinated movements to music. Over the years aerobics classes have evolved to incorporate steps (step aerobics) and martial arts (aerobic kickboxing). But who created aerobic dance, and when did it become popular? Aerobic dancing was created and made popular in the early 1970s by a woman named Jacki Sorensen. Richard Simmons took over the role as the aerobic dancing king in the early 1980s, while Jane Fonda established herself as the aerobics queen. In the early 1990s, Billy Blanks made Tae-Bo (aerobic kickboxing) popular. Fitnessprofessionals will continue to use their creativity to produce new types of aerobic dance classes that get people moving. Maybe that fitness professional is you!
You’re not able to do anaerobic physical activities for long periods because you have limited amounts of anaerobic fuel supplies. For this reason, you must separate bouts of intense physical activity with bouts of rest During the rest periods, your body is regenerating the anaerobic fuel so that you may engage in anodier bout of intense physical activity. The sports that require anaerobic physical activity are characterized by intense bouts of activity followed by bouts of rest. For example, hockey players work in shifts of about 45 seconds and then rest while other players take the ice. Football players engage in explosive bouts of physical activity that last about 15 to 20 seconds and then rest between downs. Soccer also requires anaerobic physical activity interspersed with periods of rest.

SNOWBOARDING

Snowboarding, winter sport with roots in skiing, surfing, and skateboarding where the primary activity is riding down any snow-covered surface while standing on a snowboard with feet positioned roughly perpendicular to the board and its direction, further differentiating it from skiing, in which riders face forward. Moreover, no poles are used as in skiing, and the majority of participants wear not hard but soft- to mid-flexing boots for support. The sport developed in the 1960s and ’70s, grew in popularity in the 1980s, and became an Olympic sport in 1998. To die-hard riders and enthusiasts worldwide, including this author, snowboarding is a special kind of “medicine for the soul,” combining the beauty of nature, the thrill of competition, and the opportunity for self-expression. There is no single way to snowboard.
The precursor of the modern snowboard came about in 1965, when engineer Sherman Poppen of Muskegon, Michigan—the widely acknowledged “father of the snowboard”—invented the prototype that paved the way for the modern board. The “Snurfer” got its snappy name from Poppen’s wife, who neatly combined the two words that described the contraption’s purpose: surfing on snow. Poppen’s initial model was just two snow skis bolted together—he later attached a rope to the front for steering. No specialized boots or bindings were required.
