The present invention discloses a method for providing an exercise guiding. Determine at least one mathematical correspondence to divide a coordinate plane into a plurality of regions for defining a plurality of two-dimensional exercise training zones, wherein the coordinate plane has a first axis based on a first parameter of a fitness performance level and a second axis based on a second parameter of an exercise intensity. Transform the plurality of two-dimensional exercise training zones into a plurality of one-dimensional exercise training zones of a current value of the fitness performance level for a user having the current value of the fitness performance level. Provide the exercise guiding for the user according to the plurality of one-dimensional exercise training zones.

A personal physical conditioning system, for a single, full-size human subject, has a sealable chamber that is configured to allow entry therein and occupancy thereof by the entirety of the single, full-size human subject and to allow the subject to exercise in a standing position using an item of physical conditioning equipment entirely contained within the sealable chamber. The system also has a ventilation system, including a pump, operable to change air in the sealable chamber and to establish, within the sealable chamber, a desired non-zero air pressure level of less than 1 atmosphere and down to pressure conditions substantially equivalent to an elevation of 25,000 feet above sea level. Related methods are also provided.

A method and a system for determining the maximum heart rate, called HRmax of a user of in a freely performed physical exercise and using an apparatus with software and memory. An intensity model takes account of, in addition to heart rate, respiration rate and/or kinetics information.

A system or a method for assisting an individual to acclimatize to hot environment prior to being exposed to the hot environment using a measured heart rate with or without a measured skin temperature and/or a measured body core temperature. A Physiological Strain Index (PSI) or adaptive PSI (aPSI) is calculated for the individual to provide a target for the individual's exertion level such that an area under the calculated PSI/aPSI curve is used to determine the amount of heat acclimatization that has occurred for that particular training session and/or prior training sessions.

Aspects relate to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.

According to one embodiment, an apparatus comprising a portable monitoring device to be affixed to a user. The portable monitoring device including: 1) a set of one or more sensors to generate sensor data indicative of physical activity of a user when the portable monitoring device is affixed to the user; and 2) processing circuitry coupled with the set of sensors, to detect that the user has been sedentary for a period of time, and cause the portable monitoring device to alert the user responsive to the detection to encourage the user to move.

An exercise load estimation method includes a measurement step of measuring a heart rate of a target person who exercises, and an estimation step of estimating an exercise load on the target person based on the measured heart rate and a length of a measurement period in which the heart rate was measured. The estimation step includes an exercise intensity calculation step of calculating an exercise intensity of the target person from the heart rate measured in the measurement step, and an exercise load calculation step of calculating the exercise load based on the calculated exercise intensity and the length of the measurement period.

Methods, systems and devices are provided for motion-activated display of messages on an activity monitoring device. In one embodiment, method for presenting a message on an activity monitoring device is provided, including the following method operations: storing a plurality of messages to the device; detecting a stationary state of the device; detecting a movement of the device from the stationary state; in response to detecting the movement from the stationary state, selecting one of a plurality of messages, and displaying the selected message on the device.
