here's an extract:
Endurance athletes have traditionally been encouraged to consume 1.2 g of carbohydrate per kg of body weight immediately after training/competition (8,10). In addition, they are encouraged to continue this supplementation every 2 hours up until 6 hours after their exercise bout. Recent evidence, however, indicates that the addition of protein to a carb drink can actually increase insulin levels higher than carbs alone (11,12). There seems to be a synergistic insulin release with protein plus carbs.
The current recommendations for endurance athletes have therefore changed to include protein. Eating every 2 hours is still recommended, but now endurance athletes are encouraged to consume 0.8 g of carbs per kg of bodyweight in combination with 0.4 g of protein / kg of bodyweight. This means that a 154 lb endurance athlete should be consuming 56 g of carbs and 28 g of protein at each meal: right after training, and 2, 4, and 6 hours after training.
Since most of the research on this topic has been done in endurance athletes, we have to speculate about what strength athletes would need in this regard. From the research, it's clear that strength athletes actually have higher glycogen synthesis rates after exercise than endurance athletes so they can more rapidly refill their glycogen stores (13).
But since strength athletes don't deplete their glycogen stores as badly as endurance athletes, they would need fewer total calories. With this said, I believe it's reasonable to suggest that a strength athlete consume one meal of 0.8g of carbohydrate and 0.4 g of protein / kg of body weight immediately after training.
This means that the 154 lb weight lifter would need 56 g of carbs and 28 g of protein while the 220 lb weight lifter would need about 80 g of carbs and 40 g of protein after a weight-training workout. Since glycogen synthesis rates are so high in strength athletes, they would only need to consume this type of meal immediately after the workout and then resume normal eating about 2-3 hours later.
If the strength athlete is in a bulking cycle, the post-workout recommendations would include 2 servings of recommended formula, one immediately after training and one 30-60 minutes later. Normal eating could be resumed 2-3 hours later.
