Breaststroke posture learning limiter

Abstract

The invention discloses a breaststroke posture learning limiter which comprises an upper limb limiting plate, a lower limb limiting plate and a back floating plate, wherein the upper limb limiting plate and the lower limb plate are fixed through fastening screws or mortise and tenon joints; the back floating plate is connected with the lower limb limiting plate through binding laces; the upper limb limiting plate is Y-shaped and comprises a support plate I; the upper part of the support I is circular arc-shaped; the support plate I is provided with two arm limiting parts which extend outwards and correspond to the upper limbs of a human body; the lower limb limiting plate takes the shape of an inverted Y and comprises a support plate II; the support plate II is provided with two leg limiting plates which extend outwards and correspond to the lower limbs of the human body. By adopting the breaststroke posture learning limiter, the mode that in conventional breaststroke posture teaching, a practicer can only learn the breaststroke posture through observation of a coach, proprioception of the practicer and language communication about the swimming action is changed; as the body of the practicer can be limited by the arm limiting plates and the leg limiting plates of the breaststroke posture learning limiter, a beginner can learn the standard swimming posture conveniently, rapidly and comprehensively.

Description

technical field [0001] The invention relates to a sports equipment, in particular to a limiter for breaststroke stroke learning. Background technique [0002] Swimming is deeply loved by the general public and has a solid mass base. In particular, breaststroke is the most labor-saving (lowest physical requirement for swimmers) and the most popular stroke, and it is also the stroke that beginners must first master. However, in terms of technical links: among the four strokes (breaststroke, freestyle, backstroke, butterfly), breaststroke has the most technical requirements. ⑵Breaststroke leg movements, when the legs are retracted, the angle formed between the legs and the trunk is required to be 120-140 degrees, and the inner knee width of the two knees is the same width as the practitioner's shoulders; ⑶Breaststroke leg movements are retracted In the leg movement, when the leg is retracted, the practitioner is required to receive the heel close to the buttocks. The standard...
