Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of sports equipment, specifically a kind of balance training wobbly log balance bridge. BACKGROUND

[0002] As a kind of training equipment, log balance bridge has multidimensional effect in dance balance training, and log balance bridge forces trainee to mobilize core muscle group (abdomen, back, hip) to maintain body stability through narrow support surface, which is highly consistent with the requirement of continuously controlling trunk stability in dance, for example, single foot rotation and jumping action in dance rely on core strength as support, and walking training of balance bridge can effectively improve this ability, in addition, lower limb muscle (such as calf, thigh muscle group) continuously exerts force in balance process, which can enhance leg strength and endurance, and provide basis for movement and jumping action in dance.

[0003] Dance action often involves complex limb coordination and gravity center shift, and walking of log bridge needs to accurately adjust each part of body (such as arm swing, waist twist) to maintain balance, which is consistent with the training goal of coordination in dance, for example, balance beam training can strengthen "bilateral coordination" ability, and jumping and tilting action in dance needs to rely on dynamic balance, and practice of balance bridge can simulate such unstable environment to help dancer adapt to variable gravity center adjustment.

[0004] When walking on narrow balance bridge, dancer needs to accurately judge the relative position of body and support surface, and control step and foot point, which is directly related to the control ability of space and action route in dance, and action on balance beam needs to "adjust gravity center in limited space", and formation change and fixed point action in dance also need such space perception ability, in addition, instability of log bridge can also train fine control of dancer on muscle, so that action is more smooth and accurate.

[0005] Challenge of log bridge training on psychological state is similar to stress situation in dance performance, and repeated attempt to overcome balance failure can cultivate patience, determination and anti-frustration ability, and dance student often needs to face unexpected situation (such as wet ground, clothing restriction) on stage, and training of balance bridge can enhance its on-the-spot response ability and improve psychological stability during performance.

[0006] Insufficient balance ability is one of important reasons for falling or sprain in dance, and log bridge training can reduce the risk of injury in dance action by strengthening small muscle group (such as ankle joint surrounding muscle group) and joint stability, for example, core strength is the basis of "action stability", and good balance force can avoid "falling and injury".

[0007] But the bottom support of the current balance bridge is fixed, and it is easy to walk on the bridge, so the training effect of balance is low, and as the requirement of dance is improved, the requirement of balance is also improved, so a balance bridge capable of swinging is needed to meet the requirement of high-difficulty dance balance training.

[0010] Further, the bottom surface of the conical structure of the swinging cavity is provided with an upwardly protruding spherical arc surface, the center of the spherical arc surface coincides with the center of rotation of the support ball in the spherical clamping groove, the upper end of the limiting swing column is fixed with a ball seat, the upper surface of the ball seat is provided with freely rolling balls, and the balls are in contact with the spherical arc surface.
