摘要

This study was intended to determine various indices of motor ability in 5- to 7- year-old children, born at extremely low birth-weight (ELBW: 500-999g, n = 14, 6.4 ± 0.1y) and very low birthweight (VLBW: 1000-1499g, n = 20, 6.7 ± 0.1y) with no manifestation of any overt neuromuscular disability in comparison to normal birthweight (NBW: > 2500g, n = 24, 6.4 ± 0.1y) term controls. The following data were collected: simple reaction time (RT) of the legs (msec), several components of whole body and inter- and in-tralimb coordination (MQ), maximal cycling speed (CSmax) (rpm) of a 30 sec cycling task at ,,zero" resistance (Fleisch Metabo, Switzerland), anaerobic muscle endurance (MP) and power (PP) (30 sec Wingate Test). The main finding was a deficiency in performance of the ELBW children compared with the VLBW and NBW groups (p < 0.05). Results: Mean RT: 403±115, 339±58, 342±48 msec for ELBW, VLBW and NBW, respectively; MQ: 73.4±10.3, 81.5±11, 84.6±.4; CSmax: 128±13, 143±11, 143±13 rpm; PP/kg: 6.2±0.8, 7.210.9, 7.3±1 W·kg~(-1); MP/kg: 3.8±0.6, 4.8±0.6, 4.5±0.5 W·kg~(-1). These findings suggest that ELBW, associated with a complicated perinatal course, is likely to result in a delayed motor ability in such children, due to deficiencies in neuromuscular control.
