Validation of a ski simulator
The use of simulation devices to improve the motor performances of athletes is becoming increasingly popular. It was the purpose of this study to determine the validity of a ski simulator (Dukane, Model 14A635). It was hypothesized that this device would not only differentiate among skiers (N = 60) and nonskiers (N = 20), but that it would also classify skiers (N = 80) according to their levels of proficiency, i.e., nonskiers, beginners, intermediates, and advanced skiers. The validity of the simulator was established through the use of divergent groups. A deliberate sampling procedure was utilized to select 20 female subjects for each of the above 4 groups. The subjects ranged in age from 18 to 26 yr and were tested individually under controlled laboratory conditions. After a practice trial at a speed of 6 rpm each subject took 3 trials at slow (6.5) rpm, medium (7) rpm, and fast (7.5) rpm speeds. A 1-min rest period was interspaced between each trial. The simulator recorded automatically an error score for each gate missed during each of the 3 trials. Data were analyzed through the use of 4 X 3 repeated measures design. Statistically significant differences (.001 level) in foot-eye coordination were found among the 4 groups of skiers. Advanced skiers made the least number of errors at medium (7) rpm and fast (7.5) rpm speeds. It was concluded that the simulator was a valid instrument at medium (7) rpm and-fast (7.5) rpm speeds. Except at slow speeds (6.5) rpm, all subjects made more errors as simulation speed increased. © 1975 Taylor 8 Francis Group, LLC.
