What are some examples of muscular endurance in sports?
Endurance is considered by exercise physiologists to be a little different than aerobic efficiency.
Generally, it's the ability to perform at a high level, but one that is less than maximum, for a prolonged period.
"Strength" is the ability to perform short, hard, "maximum" output. Like lifting a heavy weight.
Endurance would be to lift a less-than-maximum weight for as many repetitions as possible.
So sports like rowing require not only high aerobic capacity, but also considerable muscular endurance. Others might be the long-distance sprints, where the body is taken outside of it's "anaerobic threshold" (about 10–12 seconds of max effort) and must continue for considerably longer than that.
Wrestlers must have great endurance as well; they are often working very close to their maximum effort level for minutes at a time.
