Different sports will have different muscular demands. And different levels of experience will have different levels of efficiency. So heart rates and zones will vary from sport to sport.
For example, most of my training has been weight-bearing for the past twenty years and exclusively for the past six. I’m less serious about my performance in those sports, and I’m curious about cycling, so I’ve started biking. My legs are decently strong for weight-bearing sports, but weak for cycling. And I have very little cycling experience. So I can’t hit the same heart rates cycling that I can running or skimo-ing.
Variations per sport also apply to VO2 and lactate tests.
