As for total work done, the statement is irrelevant: the work required in lifting a 1Kg mass at sea level isn't (largely) different at 8,000m. However, it's the efficiency of the machinery that changes. That's probably where future research will go. Not biomechanical (hardware) but hormonal (software).
