Answer:

the more efficient a heart is, the less work it has to do for a given workload, so it beats fewer times per minute.

Answer:

A "normal" RHR falls between 60 and 100 beats per minute. An RHR under 60 can indicate that youre more physically fit and may be associated with better heart function.An RHR that is above 100 beats per minute can reflex exposure to stress ,excessive caffeine consumption or an illness.
