Abstract:
BACKGROUND: High-speed exercise is an essential training component
to prepare athletes for competition. To date correlations between
anthropometry and high-speed exercise performance are mixed. OBJECTIVE: To assess anthropometry as a correlate to performance
from workouts comprised exclusively of tonic or phasic repetitions done on a
high-speed resistive exercise device (Impulse Training Systems; Newnan, GA). METHODS: Male athletes (n = 31) did two workouts that involved
performance of a standing unilateral rowing motion with their left arm for
two 60-second sets. Each workout was comprised solely of tonic or phasic
repetitions. Anthropometric measurements included: height, mass, body fat
percentage, shoulder width, upper and lower arm lengths as well as torso
length. Mean force and total work values from each type of workout served as
criterion variables. RESULTS: Anthropometry predicted significant amounts of variance
for both mean force and total work values (r2 ∼ 0.21) from tonic workouts. However anthropometry failed to predict a
significant amount of performance variance from phasic workouts. CONCLUSIONS: Anthropometry acts as a better correlate to high-speed
resistive exercise performance for repetitions that do not terminate with
impact forces and are inherently less ballistic, as the latter likely
utilizes less momentum.
