A treadmill includes a frame and a running belt coupled to the frame. The running belt is configured to rotate relative to the frame. The treadmill includes at least one sensor configured to collect information regarding a rotation of the running belt and a use of the treadmill by a user of the treadmill. The treadmill also includes a light source coupled to the frame and configured to emit a light at least partly away from a front of the treadmill to at least partly illuminate a rear of the treadmill.

A method is provided of evaluating comparative equivalence for a user of a Differential Air Pressure (DAP) system between an unsupported exercise session and an unweighted DAP exercise session. The method includes receiving, for a comparative group of the unweighted and unsupported sessions, an unweighting for each and a 1.sup.st exercise parameter for a base selection of the group having a first gait speed and a first incline. The method includes evaluating a session output for the comparative group based on the first gait speed and incline and an unweighting (if any) of the base selection, which includes determining, for a comparison selection of the comparative group and the session output, based on an unweighting of the comparison selection, a 2.sup.nd exercise parameter having a second gait speed and a second incline. The method further includes providing the output and comparative information including the second speed and the second incline.

In a first aspect, a method is provided that includes the steps of (1) providing a monitor for determining a level of exercise performance performed by an exerciser and for outputting a signal representative of the performance level; (2) using the monitor to measure a level of exercise performance performed by an exerciser; (3) outputting from the monitor a signal representative of the performance level; (4) providing a video game having a character, the video game inputting and being responsive to the performance level signal output by the monitor, the video game using the performance level signal to control a performance level of the video game character; and (5) while the exerciser is not exercising, controlling a performance level of the video game character based on a performance level signal output by the monitor.

A treadmill includes a frame, a running belt coupled to the frame, and a handrail coupled to the frame. The treadmill further includes a display device configured to display information to a user of the treadmill, and a light source coupled to the handrail. The light source is configured to emit a light at least partly away from a front of the treadmill, whereby at least one of a color, a transition characteristic, or a brightness of light from the light source is varied based on collected use information.

A first exemplary aspect is a health promotion system using a computer, the health promotion system including: a door mechanism configured to be opened by an operation performed by a person; a control unit configured to control the door mechanism; and identification information acquisition unit that acquires identification information for identifying the person who operates the door mechanism. The control unit acquires health condition information indicating a health condition of the person, determines whether or not the health condition satisfies a target value that is predetermined for the person identified by the identification information, and increases an exercise load of the operation for opening the door mechanism when the health condition does not satisfy the target value.

The present invention relates to a base for a modular exercise system comprising: a ground element for locating the base on a surface; a resistance apparatus mounted on the ground element; an attachment means for receiving and connecting an interchangeable exercise device to the base; and at least one first sensor which is operative to detect and identify the interchangeable exercise device when connected to the base and to communicate with a processor when the resistance apparatus is engaged with a drive mechanism on the interchangeable exercise device.

A method is provided of evaluating comparative equivalence for a user of a MicroGravity system between an unsupported exercise session and an unweighted MicroGravity exercise session. The method includes receiving, for a comparative group of the unweighted and unsupported sessions, an unweighting for each and a 1.sup.st exercise parameter for a base selection of the group having a first run speed and a first incline. The method includes evaluating a session output for the comparative group based on the first run speed and incline and an unweighting of the base selection, which includes determining, for a comparison selection of the comparative group and the session output, based on an unweighting of the comparison selection, a 2.sup.nd exercise parameter having a second run speed and a second incline. The method further includes providing to the user session output and comparative information including the second speed and the second incline.
