NEW YORK – Mini trampolines, the go-to fitness tool for people seeking a joint-friendly cardio bounce, are also adding spring to the push-ups, planks and lunges of boot camp and interval workouts.
Deborah Horton, a group fitness instructor at Crunch fitness in New York City, leads a 60-minute mini trampoline, or rebounder, class called Urban Rebounding that folds planks, jumping jacks and hamstring curls into and between cardiovascular intervals.
“Rebounding is a non-impact cardio workout on a surface so soft you can bounce a raw egg on it and it won’t break,” said Horton.
To add a resistance component, Horton added, some rebounding classes incorporate free weights and body bars.
Michele Olson, professor of exercise physiology at Auburn University in Montgomery, Alabama, said rebounding is a low-to-moderate intensity form of cardio exercise that burns calories similar to brisk walking.
“The calorie burn and intensity are not as high as jogging or running,” she said, “so it could be very useful for less-fit persons, (or) those with orthopedic issues.”
But bouncing, she added, is no substitute for walking.
“Good ground-based walking stimulates the bones in the spine more and is important for preventing osteoporosis,” Olson said. “To protect the bones the feet need to hit the pavement a few times a week.”
John Hines of Bellicon-USA, a Chicago company that distributes Bellicon mini trampolines, said while rebounders are popular among seniors, sales spike among people in their 30s and 40s, and are more popular than expected among 25- to 30-year olds.
“It’s interesting how quickly we adapt to bouncing,” he said. “You can really relearn balance at any age.”
Exercise physiologist Dr. Mark P. Kelly suggests that for seniors mini trampolines have their ups and downs.
“Many older adults feel the trampoline is perfect for them with the soft landing. In reality, the older individual may be the worst candidate for using the bouncy surface due to weak ankles and poor balance,” said Kelly, who teaches at California State University, Fullerton.
Kelly said mini-trampolines are associated with ankle sprains and strains. He urges beginners to hold on to a stable object until the ankles are strengthened and the user gets used to the bouncing action. (Reuters)
