Physical fitness levels of physically active and sedentary adults with Down syndrome

The purpose was to compare physical fitness of two groups of adults with Down syndrome, one active group of Special Olympians (9 males, 4 females), and one sedentary group (5 males, and 2 females). The active group had trained Cor an average of 4.9 hr per week for a minimum of 1 year for Special Olympics competitions. Participants underwent laboratory testing, including (a) treadmill test to determine peak oxygen uptake; (b) isometric strength tests of handgrip, lower back, and quadriceps; (c) explosive power: and (d) body composition. Peak oxygen consumption and muscle strength were significantly greater in the active group. Although crossectional, these findings suggest that long term exercise training, at a greater than previously reported weekly training load, may enhance physical fitness in individuals with Down syndrome.
