<p>An underwater treadmill apparatus (10) is made up of a treadmill belt (18) trained over a drive roller (19) and take-up roller (20), a fluid drive motor (32) and flywheel (38) coupled to a common drive shaft (28) in direct driving relation to the drive roller, and an isolated power source (24) outside of the body of water includes an electric motor-driven hydraulic pump (56) to direct hydraulic fluid under pressure to the hydraulic drive motor. The upper course of the treadmill belt (18) advances over a rigid deck (75) having an upper cushion layer (120) with raised straddle portions (74) on each side, and the take-up roller (20) is resiliently mounted at one end of the deck (75). A bonding grid break (64) and sacrificial anodes (68) are provided to inhibit corrosion, and the treadmill frame (12) can be placed in compressible padding (26) and be leveled from a point above the surface of the water, for example, when placed in a swimming pool.</p> |
