caffè alleato dei ciclisti?
Secondo questa ricerca sembrerebbe di si, anche se gli atleti testati sono dei calciatori.Gli scienziati concludono affermando che una bevanda mix di carboidrati e caffeina migliora l'endurance e la concentrazione.
ScienceDaily (Dec. 14, 2011) — Caffeine combined with carbohydrate could be used to help athletes perform better on the field, according to new research by a sport nutrition expert.
Mayur Ranchordas, a senior lecturer and performance nutritionist at Sheffield Hallam University, carried out studies on footballers using caffeine and carbohydrates combined in a drink. Along with improvements in endurance caused by ingesting carbohydrate, the athletes' skill level improved after taking caffeine and carbohydrate together.
Mayur said: "There is already plenty of research that shows that caffeine and carbohydrate improve endurance, but this study shows that there is also a positive effect on skill and performance.
"We carried out three different soccer-specific match simulations of 90 minutes each -- two 45 minute sessions -- that tested agility, dribbling, heading and kicking accuracy. The test was designed to mimic a football game where the participants had to carry out multiple repeated sprints, dribble the ball around cones and shoot accurately.
"We found that the combination of carbohydrate and caffeine allowed players to sustain higher work intensity for the sprints, as well as improving shooting accuracy and dribbling during simulated soccer activity.
"These findings suggest that, for athletes competing in team sports where endurance and skill are important factors, ingesting a carbohydrate and caffeine drink, as opposed to just a carbohydrate drink, may significantly enhance performance. Our findings suggest that soccer players should choose a carbohydrate caffeine drink over a carbohydrate drink to consume before kick off and at half-time."

Spero ghe abbiano ragione perche oggi ho assunto tanta caffeina per un bel po'
Secondo questi scienziati penso che l'integratore gel dell'enervite carbo + caffeina posso essere l'ideale.
Io non l'ho mai preso, ma a voce di chi l'ha fatto (compreso te) da effetti alla HULK.
Attenzione che troppa caffeina (stessa cosa per altri stimolanti come gingseng, guarana,...) porta all'assuefazione, quindi per avere i massimi effetti caffè(ina) solo quando serve.
