<p>PROBLEM TO BE SOLVED: To reduce the cost of an oxygen gas feeding device and to enable the control of the concentration and flow rate of oxygen gas in an exercise machine for a user to take exercise while taking oxygen gas fed by the machine. SOLUTION: This exercise machine comprises, for example, a bicycle exercise machine 1 and an oxygen gas feeding device 3. The oxygen gas feeding device 3 is driven by utilizing the rotation force outputted from the rotation axis of the bicycle exercise machine 1. In addition, a pressure sensor, an oxygen concentration sensor, and a flow rate sensor are mounted in the oxygen gas feeding device 3, which is feed-back controlled based on the values detected by the sensors, so that the oxygen concentration and the oxygen flow rate are controlled.</p> |
