The Effect of Caffeine Ingestion on Anaerobic Power, Plasma LDH and Ca+ Concentration During a Maximum Activity Intermittent Performance in Young Mans Soccer Players

The present study aim is to investigate the effect of caffeine ingestion (caf : 6mg/kg) on the anaerobic power, plasma LDH and Ca+2concentration during a intensive - interval activity in the soccer players . The study was done by the semi -experimental design. Among 380 young soccer, 22 subjects were randomly selected as control and experimental groups (CG & EG), with averages of: (weight : 62.5 ±7.5 kg , height :171±5.3 cm) which have been participated during native competition league. EG and CG performed the Davise and Wingate protocols. The subjects ingested caf and placebo (dextrose) for 1 hours before price program (pp). This protocol was involved 30 min activity with 10 interval rep ><3min. Blood sampling and (AP) were measured, before, immediately and after (PP) protocol respectively. Absolute and relatively values (AP) and plasma Ca+2 concentrations were significantly increased in the (EG), however LDH concentrations were not markedly among two groups. Data showed that a given caff ingestion is caused an increased AP during (PP) in the young soccer.
