Abstract
AbstractA regular endurance training program may elicit different adaptations compared to
an isolated training method. In this study, we analyzed the effects of 8 weeks
of a regular endurance training program on running economy (RE), particularly
neuromuscular and biomechanical parameters, in runners of different athletic
abilities. Twenty-four male runners were divided into two groups: well-trained
(n=12) and recreational (n=12). Both groups
completed a 4-min running bout at 13 and 17 km·h-1,
respectively, for the recreational and well-trained group, and a 5-jump
plyometric test pre-post intervention. During the training program, participants
completed low-intensity continuous sessions, high-intensity interval training
sessions, and auxiliary strength training sessions. RE, measured as oxygen cost
and energy cost, decreased by 6.15% (p=0.006) and 5.11%
(p=0.043), respectively, in the well-trained group. In the recreational
group, energy cost of running, respiratory exchange ratio, and leg stiffness
decreased by 5.08% (p=0.035), 7.61% (p=0.003),
and 10.59% (p=0.017), respectively, while ground contact time
increased by 3.34% (p=0.012). The maximum height of the 5-jump
plyometric test decreased by 4.55% (p=0.018) in the recreational
group. We suggest that 8 weeks of regular endurance training leads to an
improvement of ~5% in RE in recreational and well-trained
runners with different physiological adaptations between groups and few changes
in biomechanical and neuromuscular parameters only in recreational runners.
