| Summary: | Background: Although anaerobic power affects soccer performance, the
relationship between anaerobic power and core strength in soccer players has not
been well studied. The aim of our study was to investigate the relationship
between anaerobic power and core strength. Methods: The subjects were 31
college male soccer players. Their physical characteristics, anaerobic power
(Wingate anaerobic test: WAnT), and core strength (isokinetic trunk strength
test; ITST) were measured. To describe the effect of core strength on anaerobic
power, the Pearson correlation coefficient and multiple regression analysis were
conducted. Results: A significant relationship between the WAnT peak
power (PP) and variables of ITST was observed (vs. trunk extension strength; TES:
r = 0.629, vs. trunk flexion strength; TES: r = 0.507, vs. trunk extension power;
TEP: r = 0.411, and vs. trunk flexion power; TFP: r = 0.555). We also found a
relationship between the WAnT mean power (MP) and variables of ITST (vs. TES: r =
0.654, vs. TFS: r = 0.559, vs. TEP: r = 0.468, and vs. TFP: r = 0.720). The
variables of ITST affecting WAnT PP were TES (P < 0.001) and TFP
(P < 0.001). The explanatory power of these variables was 59.7%
(R2 = 0.597). The variables of ITST affecting WAnT MP were TFS (P< 0.001) and TSE (P < 0.001). The explanatory power of these
variables was 72.7% (R2 = 0.727). Conclusion: The results of our study
showed that isokinetic trunk strength significantly associated with the WAnT peak
and mean power.
