Kei Tamai and his colleagues studied the physical fitness of non-disabled school-aged children born with extremely low birth weights ≤ 1000 g. The subjects were 169 ELBW infants without cerebral palsy or intellectual disability. Physical fitness was assessed using the grip strength, sit-up repetitions, sit and reach, side steps, standing long jump, and softball throw tests. T-scores were calculated using national survey data
