Study aim
The study compared the effects of speed, agility, and quickness (SAQ) training performed on grass
Materials and methods
Twenty-four male university soccer players were randomly assigned to SAQ training on grass or sand surfaces. The intervention lasted four weeks with a weekly frequency of two sessions. The variables assessed were 30-m linear sprint, CODS, countermovement jump (CMJ), drop jump (DJ; jump height, ground contact time [GCT], reactive strength index [RSI]), squat jump (SJ), standing long jump (SLJ), and triple-hop distance. A two-by-two mixed design ANOVA was used to analyze the training effects.
Results
A significant positive main effect of time was observed for CMJ, DJ, and SJ height (p < 0.001) and triple-hop distance, with significant pre-to-post improvement in both groups (all p < 0.001). In addition, a negative main effect of time was observed for DJ GCT and DJ RSI (p = <0.001–0.024), with a significant increase in DJ GCT for both groups but a significant decrease in DJ RSI only for the group training on sand. No main effect of time was found for the 30-m linear sprint, CODS, or SLJ distance (p = 0.080–0.792). An interaction effect on CMJ height was noted (p = 0.027), favoring the group training on the sand surface.
Conclusion
SAQ training on grass and sand surfaces showed similar improvements in the DJ, SJ, and triple-hop performance. However, compared to the grass surface, training on the sand surface induced greater improvements in CMJ but showed negative effects on DJ RSI.
