Research suggests that strength training can increase endurance. This should be combined with endurance work for maximum impact
increase maximum strength to a point that the specific load being lifted during repeated actions is less than 40% of the individuals' 1RM. Subsequent training should then focus on maintaining maximal strength levels and improving local muscular endurance in the specific task.
I posted a related question on our sister site for bicycles without a definitive answer, but did receive some helpful suggestions.
What exercises can I do that will allow me to work to about 3 times of the load of bicycling?
