Curve Sprinting in Soccer: Kinematic and Neuromuscular Analysis
Int J Sports Med DOI: 10.1055/a-1144-3175Sprinting in curvilinear trajectories is an important soccer ability,
corresponding to ~85% of the actions performed at maximum
velocity in a soccer league. We compared the neuromuscular behavior and foot
contact-time between outside leg and inside leg during curve sprinting to both
sides in soccer players. Nine soccer players (age=23±4.12 years)
performed: 3×Sprint linear, 3×Sprint right curve, and
3×Sprint left curve. An ANOVA with repeated measures was used to compare
the differences between inside and outside leg, and Cohen’s d was used
to calculate the effect-size. Considering the average data, the performance
classification (from best to worst) was as follows: 1. Curve
“good” side (2.45±0.11 s), 2. Linear (2.47±0.13
s), and 3. Curve “weak” side (2.56±0.17 s). Comparing
linear with curve sprinting, inside leg recorded significant differences
(“good” and “weak”; effect size=1.20 and
2, respectively); in contrast, for outside leg, there were no significant
differences (“good” and “weak”; effect
size=0.30 and 0.49, respectively). Electromyography activity showed
significant differences (p≤0.05) during curve sprinting between outside
(higher in biceps femoris and gluteus medius) and inside leg (higher activity in
