Force-Velocity Profiles of Elite Athletes Tested on a Cycle Ergometer
The present study explored the sensitivity of the force-velocity (F-V) modelling approach
obtained from maximal sprints on a leg cycle ergometer to detect selective changes of the mechanical
capacities of the lower body muscles associated with high-level training. Specifically, we assumed that the
F-V relationship parameters, such as maximum force (F0
), velocity (V0
), power (PM) and slope, would differ
among individuals of different high-level training backgrounds. In total, 111 elite athletes divided into four
groups (Combat sports, Athletic sprints, Team sports and Physically active) performed maximal sprints on a leg
cycle ergometer loaded with 7%, 9%, and 11% of body weight. The findings obtained suggest an exceptionably
strong and linear F-V relationship in most of the participants (r > 0.95), while higher PM have been found
in all groups of athletes compared to the Physically active group (p < 0.05). In addition, sport-specific F-V
profiles have been observed in athletes that belong to distinctively different sports (i.e. higher F0
and forceoriented
slope for strength-trained Combat sports and higher V0
for speed-trained Athletic sprints). To our
knowledge, this is one of the rare studies that evaluate the F-V profiles with such a large sample of elite athletes
obtained from commonly used task such as maximal sprints on a leg cycle ergometer. The results obtained
support a high sensitivity of the F-V modelling approach to distinguish among elite athletes with different
training histories
