Claim 18:
19. A Method for controlling a differential air pressure (DAP) system during use by a user for a current unweighted exercise session, the DAP system comprising:
an inflatable enclosure having a base extending upward when inflated from the base to a top opening defined therein and configured for attachment with a user seal interface;
a platform for retaining an exercise device and securing the enclosure base above the exercise device;
a pair of powered vertical lifts secured to the platform, each having a vertically drivable carriage;
a seal frame connected to each carriage extending about the top opening and attached to the enclosure proximate the top opening; and
a control system computer operatively connected to the exercise device, an inflation source coupled to the DAP system in an airtight connection, and the pair of powered lifts;
wherein a user seal worn by a user comprises an interface configured for secure, airtight attachment with the top opening during use of the DAP system for unweighted exercise;, the method comprising:
calculating a user seal interface height based on an estimated height for the user;
determining, based on the user seal interface height, an attachment carriage height and a usage carriage height different than the user seal interface height;
driving the powered vertical lifts to raise each carriage to an attachment position at the attachment carriage height;
confirming attachment of the user seal interface to the top opening;
responsive to the confirming attachment, driving the vertical lifts to move each carriaae to a usage position at the usage carriage height;
inflating the enclosure comprising operating the pressure source to inflate the enclosure to an unweighting pressure and controlling the lifts to retain the usage position;
calculating an output for the user for the current unweighted exercise session and for an equivalent non-unweighted exercise session based on exercise parameters for each session, the exercise parameters comprising a speed, a %grade, and a %bodyweight for each session, wherein:
the %bodyweight for the non-unweighted exercise session is a bodyweight of the user; and
the %bodyweight for the current unweighted exercise session is the bodyweight of the user multiplied by a reduced value corresponding with an unweight support percentage applied by the inflated enclosure to the user, the %bodyweight having a value less than 1.00; and

providing output information to the user for the current unweighted exercise session and the non-unweighted exercise session.
