Digital display rope skipping handle capable of informing rope skipping shrinking-second frequency

Abstract

The invention discloses a digital display rope skipping handle capable of informing rope skipping shrinking-second frequency and aims at solving the problem that at present, one-minute rope skipping athletic performances of primary and secondary school students about to enter senior high schools from junior high schools and enter the junior high school from primary schools difficultly reach the standard. Target performances (for example, 180 / minute) to be achieved are quantified at the frequency of (3 / second), the non-uniformity of the actual rope skipping process is considered, and the frequency-shrinking-second target frequency F' slightly higher than the target frequency is adopted for rope skipping. A circuit part of the rope skipping handle is provided with a 'shrinking-second time base generating and output device', and the ratio of 'shrinking-second time base voice output by the device to actual rope skipping times n within the interval time T of two time base voices is real-time rope skipping shrinking-second frequency f'. The f' is regulated to be equal to the F', constant-speed rope skipping is performed to the greatest extent for one minute, and above 98% of results reach or slightly exceed target performances. The preset number in a circuit is relatively fixed, and the digital display rope skipping handle can be used for exercise / competition and has low production cost.

Description

technical field [0001] The invention relates to a portable sports equipment, in particular to a rope skipping handle with auxiliary exercise function. Background technique [0002] The one-minute rope skipping score is an important sports achievement for elementary school to junior high school and junior high school to high school. For example, junior high school to high school requires 180 times of rope skipping per minute to be "excellent". This "excellent" score is the target score for junior high school students to practice rope skipping. We use Q to represent it. Q=180 [times / minute] This target score includes the speed of movement of students' hands and feet, physical coordination ability and physical endurance in the case of rope skipping. requirements. In practice and training, exercise speed, coordination ability, and physical endurance in the case of fast ˉˉrope skipping. These three aspects must be practiced for a certain length of time, and gradually meet the re...
