Some exercises make muscles tired faster. This study looked at how a special exercise (50 knee bends) made muscles tired in two groups: regular active people and elite runners.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

When active young men do 50 knee extension exercises to exhaustion, their muscles get tired faster afterward—about 22% more tired—showing this workout really wears out their muscles.
For top runners, doing 50 knee exercises in a special machine doesn't make their leg muscles get tired in a way that changes how quickly they fatigue, so it doesn't really affect their muscle tiredness after the workout.
When people do a special warm-up exercise, regular active folks get more tired, but top runners don't get any more tired—showing that your past exercise habits change how your muscles react.
When you do exercises back-to-back with little rest (pre-exhaustion training), it feels harder than doing exercises with normal rest breaks (traditional training).
