Question

question:
jashon has taken a month-long break from running and is trying to get back into it. he has found that he can no longer run as far as he used to. why is this likely the case?

answer options:
select one of four
jashon has detrained.
jashons max heart rate is higher.
jashons stamina has increased.
jashon is taller now.

Explanation:

When a person stops regular exercise like running for an extended period, their cardiovascular and muscular endurance decreases, a process called detraining. The other options are incorrect: a higher max heart rate would not reduce running distance, increased stamina would let him run farther, and height does not change noticeably in a month.

Answer:

Jashon has detrained.
