The effect of caffeine on heart rate during and after both aerobic and anaerobic activity

Caffeine is an alkaloid synergistic properties of the troop, with little information on the effect of caffeine on heart rate during exercise and intermittent exercise protocol are aerobic an anaerobic. Hence, this study investigated the effect of caffeine on heart rate during and after exercise, both aerobic on athletic young introduction anal target. 30 young footballers in aerobic and anaerobic exercise intensity of 80% maximal oxygen uptake participated (the average age 23/60±3/7 year and average weight 83±31 kg). Height, weight, maximal oxygen consumption rate was measured in subjects be for and after exercise. The independents t test was for statistical analysis. The results showed that maximal oxygen consumption and anaerobic power were significantly increase in the experimental group (p<0/05). In contrast, showed a significant decrease in heart rate (p<0/05). The result of this research shows that consumption of at least 6 mg/kg of caffeine on aerobic and anaerobic average there were significant effects.
