Water aerobics builds endurance and flexibility

By Bette kson For the Enterprise

No doubt about it. Water aerobics improves cardiovascular conditioning. Because of the water's resistance, participants benefit from increased strength and flexibility, leading to better muscular endurance and balance. And Broomfield resident Showalter is a believer. "It's less impact than floor work," she said. "I love it. Although it was difficult starting back up following the holidays."

Water provides buoyancy and support for the body, so the likelihood of muscle, bone or joint injuries is nearly eliminated when exercise is performed in a pool, lake or the ocean, said water aerobics instructor Diann . "Since water aerobics is often done in chest-deep water, this type of exercise appeals to swimmers and non-swimmers alike," said Becky Giuliano, another instructor at the center. Some classes at the BRC use equipment such as kick boards, floatation belts and hand buoys. A typical water aerobic workout will last an hour, with time devoted to warm-up, cool-down and stretching routines. Many of the aerobic water programs include a toning and strengthening component, as well as the aerobic portion. People of all ages and fitness levels can enjoy water workouts, said. When submerged in chest-deep water, about 85 percent to 90 percent of the body weight remains supported. As a result, much less stress is placed on the body. The BRC offers early morning water aerobics classes as well as evening classes to suit a variety of schedules. How many calories does a one-hour water aerobics class burn ? That depends, and Giuliano said. Participants are encouraged to work at their own pace. In general, a water workout expends more energy than a similar land-based exercise because of the resistance of the water. The average person burns 450-700 calories during one hour of sustained aerobic activity. When performing aquatic exercise, be aware that your heart rate may not be the best indicator of the intensity of your workout. Studies have shown that people who participate in both land- and water-based exercise often find their heart rates lower during water exercise, yet they receive the same benefits. And remember: Never swim or exercise in the water alone. Even the most experienced swimmer can encounter an in-water emergency that requires the assistance of another person.
