Land Classes

The benefits of participating in aerobics derive from the focus of the class and the frequency of your participation. A class that meets only once a week has limited health benefits, although it might be fun as a change of pace from a more traditional exercise regimen. Look for a class that meets at least three days per week in order to reap any fitness gains. Studies have shown that aerobics participation reduces pain and improves lower-extremity function, strength, walking speed or distance, and aerobic power, which is an estimate of aerobic endurance from a short activity (Perlman et al. 1990; Noreau et al. 1995). Most of these studies also found decreased depression after completion of a class. They have identified cardiovascular benefits only when the frequency is at least three times per week and the intensity is appropriate (as identified in chapter 3--50 to 85 percent of HRR).
