Abstract Resume

Background:The Dark chocolate (DC) is abundant in flavanols that exert benefits to cardiovascular system is well known to anti degenerative and antithrombotic actions. Complementarily
the physical exercise has been shown to mobilization substrates with decrease the cardiometabolic risk in prehypertension subjects. However, the impact of DC consumption associated of physical
exercise in cardiometabolic factors is uncertain. Therefore, the aim of this study was to compare the effect of chocolate with 85% cocoa add to acute physical exercise on cardiometabolic parameters of
prehypertension subjects.

Methods:Eight male volunteers prehypertension (age 31,8 ± 5.6 years; body mass 87,5 ± 17.0 kg) participated of 3 phases of the study. In the first phase the volunteers received all
information about  study, exercise electrocardiography with ergoespirometry to determine the threshold 1, 2 and maximal oxygen uptake. In the Phases 2 and 3 was collected blood before and immediately
after the exercise protocol. In these phases the volunteers was carried out the Treadmill Exercise Protocol (starting at 5 km/h increased by 1 km/h every 3 minutes) with DC supplementation (Phase 3)
and without (Phase 2). Statistical analysis was performed using independent t-test for normal distribution data and Wilcoxon test for not normal distribution data. ANOVA two-way and post-hoc
Bonferroni was used to compare the differences between groups with the level of significance of 5%.

Results: DC supplementation significantly decreased the energy expenditure, especially in the ventilatory threshold 1 when compared with Control Group (CG) (P= 0.03). However in
maximal uptake phase the DC significantly increased the energy expenditure compared to the CG (P = 0.03). Similarly it happened with exercise time increased in DC group compared to the CG (P = 0.02).
Only with DC supplementation significantly increased Creatine Kinase (CK) (P = 0,036) and lactate dehydrogenase (LDH) (P = 0.012).

Conclusions: The protocol improve the performance of physical exercise decreasing the energy expenditure and increasing the all time for effort. The DC supplementation associated with
acute physical exercise increased the cell injury biomarker CK and LDH in prehypertension subjects.
