However, I would argue that the mass gained by lifting is minimal for most endurance athletes given the persistent catabolic state that most endurance athletes are in (I will expand on this further in Part 2, but for now suffice it to say that unless a runner is eating to gain weight, he or she will NOT gain
much muscle mass due to lifting weights).
Not exact matches
Due to the fact that women do not, and can not, naturally produce as
much testosterone (one of the main hormones responsible for increasing
muscle size) as males do, it is impossible for a woman to gain huge amounts of
muscle mass by merely touching some weights.
Remember that these people were also consuming inadequate protein and were not doing resistance exercise like lifting weights, so
much of this drop in resting metabolic rate was also
due to a drop in
muscle mass.
As was mentioned above,
due to the fact that most calculations on protein need are based solely on the amount needed to optimize
muscle mass, and
due to the fact that, in reality,
muscle accounts for less than half of the total body protein need,
much more dietary protein is needed that what has been typically suggested by researchers and instructors in the nutritional community.
