Cardiovascular fitness strengthening using portable device.

The paper describes a reliable and valid Portable Exercise Monitoring system developed using TI eZ430-Chronos watch, which can control the exercise intensity through audio stimulation in order to increase the Cardiovascular fitness strengthening.

An equivalent circuit model for onset and offset exercise response.

Background: The switching exercise (e.g., Interval Training) has been a commonly used exercise protocol nowadays for the enhancement of exerciser's cardiovascular fitness.

Modelling and regulating of cardio-respiratory response for the enhancement of interval training.

Background: The interval training method has been a well known exercise protocol which helps strengthen and improve one's cardiovascular fitness.

Purpose: To develop an effective training protocol to improve cardiovascular fitness based on modelling and analysis of Heart Rate (HR) and Oxygen Uptake (VO2) dynamics.

Methods: In order to model the cardiorespiratory response to the onset and offset exercises, the (K4b2, Cosmed) gas analyzer was used to monitor and record the heart rate and oxygen uptake for ten healthy male subjects.
