<prompt> Which of the following adaptations will be apt to increase the work capacity at high altitudeIncreasing workload, decreasing duration of exerciseIncreasing workload, increasing duration of exerciseDecreasing workload, increasing duration of exerciseDecreasing workload, decreasing duration of exercise  <response>: If we increase the workload, more oxygen will be required. At high altitudes oxygen is low. So we need to decrease the workload. At the same time, to increase the work capacity, we need to increase the duration of exercise without increasing the load.
