Breaststroke hand motion and strength exerciser

Abstract

The invention provides a breaststroke hand motion and strength exerciser. The breaststroke hand motion and strength exerciser comprises a base, a prostration cushion, retractable support bars, palm fixing sleeves and a track limiting unit and is characterized in that the upper ends of the retractable support bars are connected with the palm fixing sleeves through spherical hinge pairs, and the lower ends of the retractable support bars are connected with the base through spherical hinge pairs; the track limiting unit is formed by connecting two symmetrical elliptical rings. During exercise, the retractable support bar can be operated along the inner walls of the elliptical rings and accordingly can completely limit and simulate the standard motion track of breaststroke hand motions; meanwhile, elastic ropes are connected between the retractable support bars and the elliptical rings, so that exercises on hand strength required by the breaststroke sport can be achieved.

Description

technical field [0001] The invention belongs to swimming training equipment, in particular to a breaststroke hand movement and strength training machine. Background technique [0002] As we all know, swimming exercise can not only improve the functions of nerves, breathing and blood circulation, but also improve muscle strength, speed, endurance and joint flexibility, so that the body can develop in harmony, and learning breaststroke well is the basis for learning other strokes. However, the breaststroke technique is the most complicated movement, in which the hand movement is a complex spatial trajectory, which requires a lot of repeated standardized exercises. For this reason, some land training equipment for breaststroke hand movements have been invented, but none of them can fully restrain and imitate breaststrokers The standard movement trajectory of the upper body movement, and the resistance of the hand during the real breaststroke cannot be perceived, and the effect ...
