SUMMARY:

Caffeine ingestion, is recognized to increase performance in laboratory experiments and in field studies. However, few studies have addressed habituation to chronic caffeine ingestion, which is valuable from a practical standpoint given the high number of athletes who consume caffeine daily. To assess sprint performance measures the evaluation parameters are critical to consider sprinting as a crucial physical determinant for performance in team sports. Based on this, they proposed an alternative to evaluate the entire force-velocity (Fv) spectrum during sprint acceleration, i.e., the horizontal Fv profile, in order to obtain more understandable and meaningful information about the determinants of linear sprint performance. The aim of the study was to evaluate the effect of chronic caffeine supplementation on parameters of the strength - speed - power relationship in high intensity and short duration exercise in soccer players. This is a quantitative, experimental and longitudinal research. The sample consisted of 17 male soccer players of the under-17 category, members of the same soccer team that regularly participated in the competitions offered by the Federação Alagoana de Futebol in Maceió. The anaerobic performance was evaluated by the sprint test. Descriptive statistics are presented as mean ± standard deviation. The Dvideow application was used to analyze the sprints and the best attempt was used to determine the components of the horizontal mechanical Fv profile. A one-way repeated measures analysis of variance (ANOVA) was used to explore the effect of treatment between groups over the weeks. The study revealed significant differences between time points for the caffeine and placebo groups in the F0, v0, Slope, Df, and Pmax variables (p < 0.05), but not for max (RF) (p = 0.05) and total time (TT) (p = 0.287). Among the significant differences presented in the caffeine and placebo groups, the variables v0, max (RF) and TT showed important results (p < 0.05). The other variables did not present significant differences (p > 0.05). When comparing the two groups according to the interaction between treatment and time, both did not present significant differences in any of the variables presented by the study (p > 0.05). After analyzing the sprint test performed in the caffeine and placebo groups, we found that the effects did not present substantial differences.
