Abstract: An exercise intensity assessing system includes a physiological information sensor, a signal transmitter connected with the physiological information sensor, a central control host connected with the signal transmitter, and a cloud database connected with the central control host. The physiological information sensor senses physiological information of an exerciser before and after the exerciser exercises. The physiological information is transmitted by the signal transmitter to the central control host, and transmitted by the central control host to the cloud database for being diagnosed and analyzed by a fitness instructor. The cloud database obtains a forecasted watt value corresponding to the physiological information, and obtains a resistance level of different fitness apparatuses according to the forecasted watt value.

Abstract: An intelligent exercise intensity assessing system includes an exercise testing machine, a physiological information sensor, a signal transmitter connected with the physiological information sensor, a central control host connected with the signal transmitter, and a cloud database connected with the central control host. The physiological information sensor senses physiological information of an exerciser before and after the exerciser operates the exercise testing machine. The physiological information is transmitted by the signal transmitter to the central control host, and transmitted by the central control host to the cloud database. The cloud database analyzes the physiological information to obtain a corresponding forecasted watt value, and obtains a resistance level of different fitness apparatuses according to the forecasted watt value.

Abstract: The present invention relates to a stunt kite comprising a kite with shroud lines and spars in a way arranged to improve flying performance; and a control mechanism composed of a control rod which acts as a lengthened arm of force in order to achieve an easy control of kite, a flying line regulator to regulate two flying lines connected with corresponding shroud lines of the kite so as to obtain sensitive and responsive flying, and a spool device in a way arranged to maneuver the flying lines so that the kite can be launched and retrieved from the hands.
