Metabolic Cost Comparison of Running on an Aquatic Treadmill with Water Jets and Land Treadmill With Incline


This study, conducted at Utah State University, compared the metabolic cost at specific inclines while running on a land treadmill to running speeds with selected jet resistance on an aquatic treadmill. The results showed that an increase in speed and incline on a land based treadmill shows a linear increase in the metabolic cost comparison, whereas on an aquatic treadmill it shows a more cubic change. Running with selected jet resistance on an aquatic treadmill results in greater change in metabolic cost than running on a land treadmill.
