PowerBar Protein Plus bar presence some peculiarities. The weight of each bar, about 55 grams, is superior to competing products that typically offer about 40 grams, then we can see that there is an overall low caloric intake, due, no doubt, from the low-fat, about 6%, which is very small. These positive characteristics is matched by an excellent protein content, about 30%, and reached a high value from few other competitors, which offer a higher level of fat and calories. We then tried to make the training of about two hours, in which the athletes were regularly fed and hydrated, followed by a rest period of about an hour, in which athletes were reinstated, and then a new round of training two hours. Athletes from time to time shall be replenished with a protein bar Powerbar Protein Plus, with a regular protein bar and a plain ham sandwich. We then analyzed the performance of individual athletes, according to the different supply systems, without underestimating the specific level of preparation for each athlete, his ability to recover after exercise and at a general athletic. All athletes have found the PowerBar Protein Plus bars taste pleasant, but above all to easy assimilation. No athlete has had absorption problems or reduced digestibility. Evaluating the performance difference in the second part of the physical test we have considered the integration with the classic sandwich as a baseline performance and analyzed the increase or decrease in performance by integrating with different fingers. In general, at least in our specific tests, integration with the classic sandwich has been the most inconvenient. In fact, although there was a good supply of carbohydrates and proteins, the slow assimilation of the product has prevented all athletes to take over the effectiveness of training after only an hour break. We do not deny that if the break had been about three hours, the results could be different. PowerBar having a low-fat and a good supply of calories and protein has allowed an effective reintegration of lost energy, with a rapid assimilation, so they can effectively return to training. The bars for comparison were richer in fat, smaller in size, were therefore slower assimilation. Again if the break between the two training sessions had been longer the results would have been better, though already well above the classic sandwich. In general, therefore, the PowerBar Protein Plus bars were very effective, easy to assimilate and with a good protein intake. Being low in fat and with a modest calorie intake are perfect for those athletes who need a meal post-workout or race, low calorie, to better control the weight. In general in our test all athletes have had in the second part of the training performance of more than 5% compared to other protein bars and 10% compared to the classic sandwich. Important values, but we point out, can vary greatly depending on the version of the test and, although indicating the efficacy of the product in general, can not be taken as an absolute reference point. But the PowerBar Protein Plus bars have proved their unquestioned validity. PowerBar recommends them only as a post-race meal, but we saw their rapid assimilation and digestibility, we feel we can recommend it as a meal pre-race intake with at least one hour before the sporting event, if PowerBar also in the catalog are no other specific products such as pre-race food. This, however, testifies to the validity of the bars Protein Plus cost of each finger is about 1.8 Euro (on line) or about 2.3 Euro (in stores) at very competitive prices in the report for the weight of the rod and its great effectiveness. A great product, perhaps the best available today, such as food after the race.
