Exercise workout support device

A device is provided, which is capable of determining the maximum oxygen uptake quantity without the restriction of a large device or requiring troublesome operations to be carried out. The device displays the upper and lower limit values for the pulse rate corresponding to an appropriate exercise intensity, and realizes in a wireless manner by means of optical communications the sending and receiving of information such as pulse wave signals to and from an information processing device which processes pulse wave information. The device is provided with a pulse wave detector 101 for detecting the test subject s pulse waveform; an FFT processor 103 for determining the test subject s heartbeat rate from the pulse waveform; a body motion detector 104 for detecting body motion when the test subject is running; an FFT processor 106 for determining the pitch from body motion during running by the test subject; exercise intensity calculator 108 for determining pitch, the test subject s stride, and the exercise intensity from body motion during running; and a nomogram recorder 109 for recording the relationship indicated by an Astrand-Ryhming nomogram, and determining the maximum oxygen uptake quantity from the heart rate and exercise intensity. The obtained maximum oxygen uptake quantity is divided by the test subject s body weight, to calculate the maximum oxygen uptake quantity per unit body weight. Next, the maximum oxygen uptake quantity and pulse according to sex are determined, and the pulse rate is multiplied by the upper and lower limit value coefficients, to determine the upper limit value UL and the lower limit value LL for the pulse rate.

Non-contact real-time online vibration measurement method based on images

The invention discloses a non-contact real-time online vibration measurement method based on images, and belongs to the field of vibration measurement and analysis. The method includes the steps that a vibration process of a target object is recorded through a high-speed camera, all frames of images contained in a vibration video of the target object are extracted through vibration measurement software arranged in a computer and are stored in a memory pool opened up by the vibration measurement software arranged in the computer, a thread pool is created in the vibration measurement software arranged in the computer, corresponding image frames are extracted from the memory pool by different threads in the thread pool in order, coordinates of the images and an actual object are established so that the size conversion matrix M between the images and the actual object can be solved, and therefore actual coordinates and displacement imaged through the camera are mapped in the vibration process and a measuring result and a data curve are output. A non-contact measurement mode is adopted in the method, vibration characteristics of test objects cannot be changed, measurement accuracy is high, and vibration characteristic measurement can be conducted on vibration objects under poisonous and harmful, high-temperature and dangerous environments.
