Apparatus and methods for providing breath training. In illustrative embodiments, an operator creates a pressure, either positive or negative, in the lungs. This pressure is transferred through a mask assembly to a breathwork apparatus, which utilizes pistons moving within cylinder volumes to provide numerical feedback to an operator regarding the operator's breathing. Through breath control exercises, the operator of a breathwork apparatus can develop deeper and slower breathing habits which are more efficient. One embodiment provides a breathwork apparatus comprising an exhalation side; a transfer case; an inhalation side; and, a mask assembly, wherein the exhalation side and inhalation side are joined by transfer case which comprises a plurality of channels, such that at least a first channel of a plurality of channels terminates in an exhalation rate meter, and at least a second channel of the plurality of channels terminates in an inhalation rate meter.

A device including a first flow channel, a second flow channel and a body part including an inner volume. A first space of the inner volume is adapted to be filled with liquid and a second space of the inner volume is arranged to receive steam. The device further includes means for conveying a gas flow from the steam space of the inner volume via the first flow channel to the outside of the device during inhalation and means for conveying the exhaled gas flow from the outside of the device via the second flow channel to the first space of the inner volume. The device further includes means for measuring a flow and a temperature of an airflow, and means for adjusting the flow of the airflow mechanically and/or automatically. The present disclosure further relates to a method and a system.

A system and method for adaptive fitness testing is provided. A fitness testing application manages fitness tests on a fitness testing apparatus by collecting physiological data and calculating various performance metrics. The fitness testing application automatically reconfigures fitness tests to adopt to a user's improving fitness level.

Described herein are systems and methods for favorably coordinating a timing relationship between a musculoskeletal activity cycle and a cardiac cycle of a user. A method may include repetitively detecting a signal that correlates to a blood volume in the user; determining an actual value of the signal that varies with the timing relationship; computing a trend of the actual value of the signal; and adjusting the movement guidance based on the trend of the actual value. A system may include a prompt device configured to provide recurrently a movement guidance to the user for guiding performance of the rhythmic musculoskeletal activity; a sensor configured to provide a signal that correlates to a blood volume in the user; and a processor configured to determine an actual value of the signal that varies with the timing relationship and to adjust the movement guidance based on the trend of the actual value.

Systems and methods directed to handheld respiratory diagnostics, trainings, and therapy are disclosed. More specifically, a device that collects data associated with a user's breathing using sensors, analyzes that data to determine time series readings of one or more health-related vitals, and generates trainings and therapies to assist the user in real time is described.

A system and method for managing ventilation of a user, through the use of an oral appliance, is disclosed. The appliance is configured to fit between the user's teeth and lips or cheeks to inhibit ventilation by the user around the appliance, and includes a passageway. An airway resistor within the passageway includes an aperture that is sized to allow a metered amount of air flow by the ventilation of the user. A pressure sensor measures an air pressure in the aperture, which measurement is transmitted to an external computer processor to generate feedback data for the user.

An exercise apparatus includes a first cord, a second cord, and an adjustment mechanism. The first cord is pullable from and retractable around a first pulley. The second cord is pullable from and retractable around a second pulley. The adjustment mechanism allows for adjusting a pull-out tension provided by the first cord independently of a retraction tension provided by the first cord. The pull-out tension provided by the first cord is a tension provided by the first cord when the first cord is pulled from the first pulley. The retraction tension provided by the first cord is a tension provided by the first cord when the first cord is retracted around the first pulley.
