I've heard of resistance training increasing baseline metabolic rate due to muscle hypertrophy but not endurance sports, high impact or not. I think you just made that up
Self-selection or not, there is the weight-bearing aspect of it significantly increases the difficulty as well as muscle strain for any new runner compared to a new cyclist of comparable ability.
If you honestly believe that a nonweight bearing activity like recreational easy cycling is equivalent to comparable effort recreational easy running in terms of calorie burn and adaptation to the training, you're free to believe that.
Again, you don't need to have detailed peer reviewed studies for this sort of obvious stuff. I might as well ask for peer reviewed studies proving decisively that increased weight makes climbing on a bike harder. It's hard to find those studies - because it's so obvious.
