[0018] The following will be combined with the attached embodiment of the present invention Figure 1-3 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1 Reference Figure 1-3 A standing long jump training sole with a thickness difference design, the sole 1 includes a forefoot area 4, a heel area 5 and a toe wrapping area 3, a toe wrapping area for wrapping the toe is provided in front of the forefoot area, and a heel area is provided behind the forefoot area, and the toe wrapping area has a thickened structure.

[0020] The invention discloses a standing long jump training shoe sole with a thickness difference design, wherein a thickened structure and a forefoot area 4 and a heel area 5 form a thickness difference design.

[0021] The utility model discloses a standing long jump training shoe sole with a thickness difference design, wherein the thickness gradually becomes thinner from the rear end of the forefoot area to the rear heel area.

[0022] The utility model relates to a standing long jump training shoe sole with a thickness difference design, wherein the thickness gradually becomes thinner in an inclined plane shape from the rear end of the forefoot area to the rear heel area.

[0023] The utility model discloses a standing long jump training shoe sole with a thickness difference design, wherein the thickness gradually becomes thinner from the rear end of the forefoot area to the rear heel area in an arc shape.

[0024] The utility model discloses a standing long jump training shoe sole with a thickness difference design, wherein the front of the forefoot area is transitioned to a shoe tip wrapping area for wrapping the shoe tip through an arc surface.

[0025] The utility model discloses a standing long jump training shoe sole with a thickness difference design, wherein the thickness of the shoe tip wrapping area is consistent with the thickness of the forefoot area.

[0026] The utility model discloses a standing long jump training shoe sole with a thickness difference design, wherein a forefoot area 4 and a rear heel area 5 are made of different materials.

[0027] A training shoe made of the sole comprises a standing long jump training sole with a thickness difference design and an upper 2, wherein the standing long jump training sole with a thickness difference design and the upper are combined to form a shoe body.

[0028] The thickness difference design compensates for the height loss caused by the forward tilt of the center of gravity and increases the air time. The design of the heel area prevents premature contact and enhances landing stability.

[0029] Design principle:

[0030] 1. Analysis of the take-off phase

[0031] (1) Beginner stage: When taking off, the front of the foot is usually off the ground. At this time, the center of gravity is relatively stable and the inclination angle is small.

[0032] (2) Advanced stage: The center of gravity tilts forward more obviously during takeoff, and the final position off the ground gradually shifts to the toes.

[0033] (3) Advanced stage: The center of gravity of the jump is significantly forward, and the toes are the last part to touch the ground, such as Figure 3 .

[0034] Based on the analysis of sports mechanics, the take-off height is proportional to the time spent in the air, and the time spent in the air is the key factor in determining the horizontal distance. Therefore, high-level athletes need to maximize their take-off height and time spent in the air. However, the sole design of traditional sports shoes is thick at the heel and gradually becomes thinner towards the toe area. This design causes the original standing height to decrease at the moment of take-off, thereby losing the time spent in the air.

[0035] Improved design: Referring to the thickness of the heel of the current mainstream sports shoes, this design has a thickened structure in the toe wrapping area outside the toes at the front of the sole, making its thickness consistent with the thickness of the forefoot sole, reaching the thickness of the heel of the mainstream sports shoes. Ensure that the take-off height will not be affected by insufficient sole thickness when the toes leave the ground, and increase the air time. That is, the thickness of a = b = c, such as Figure 1 .

[0036] 2. Analysis of the landing stage

[0037] (1) Beginner stage: Before landing, the body stretches forward, the calf lags behind, the forefoot touches the ground, the center of gravity is high, and the landing stability is poor.

[0038] (2) Advanced stage: Before landing, the calf is slightly extended forward and the heel touches the ground to provide better cushioning and stability support.

[0039] (3) Advanced stage: Before landing, the lower leg is obviously extended forward, and the heel tip touches the ground first. A series of actions of contracting the abdomen and flexing and extending the legs need to be completed in the air to reduce the loss of distance caused by the lag of the lower leg, such as Figure 3 .

[0040] When landing, the protruding structure of the heel of the shoe tends to contact the ground prematurely, destroying the landing posture and reducing the smoothness and stability of the movement.

[0041] Improved design: This design cuts off the heel part of the sole and connects it with the back of the upper to eliminate the protruding part, avoid premature contact when landing, and extend the air time.

[0042] At the same time, compared with the original protruding heel corners, the chamfered heel has a larger contact area when the leg is stretched to touch the ground, which is more anti-slip and improves stability.

[0043] 3. Experiment

[0044] (1) Experimental subjects: 15 eighth grade boys aged 13-14 years old, 155-175 cm in height, and 45-65 kg in weight were selected.

[0045] Beginner level: 3 people; Advanced level: 8 people; Advanced level: 4 people;

[0046] (2) Experimental equipment and comparison shoe models:

[0047] Running shoes (students should bring their own shoes): the thickness of the toe is 5-10mm, the thickness of the forefoot area is 15-20mm, the thickness of the rear foot area is 25-30mm, and the tip of the heel protrudes backwards by 0-10mm.

[0048] Standing long jump shoes: The thickness of the toe is 30mm, the thickness of the forefoot area is 30mm, and the thickness of the rear foot area gradually decreases from 30mm to 10mm. Standing long jump shoes are patented products.

[0049] At the beginner level, wearing running shoes and long jump shoes, since the forefoot leaves the ground and lands on the ground, the take-off and landing heights remain unchanged and have no effect on the air time.

[0050] For the advanced level, the forefoot leaves the ground and the heel lands on the ground. The take-off height is increased by 15mm, the landing height is reduced by 10mm, and the hovering height is increased by 25mm.

[0051] At the advanced level, the front toes leave the ground and the back heels land on the ground. The take-off height is increased by 25mm, the landing height is reduced by 30mm, and the hovering height is increased by 55mm.

[0052] (3) Test process and data: Each student wore two types of shoes and performed three standing long jump tests. The results are as follows:

[0053] Detailed data (90 jumps in total):

[0054]

[0055]

[0056] Data aggregation and analysis:

[0057]

[0058] The results showed that the patented product performed better than running shoes at all levels, with an average improvement of approximately 7-13cm.

[0059] However, it does not mean that advanced athletes with better athletic performance will definitely make greater progress by using long jump shoes. There are even two intermediate and advanced athletes with a standard deviation of 1 cm. In this regard, we have come to the following conclusions through analysis of sports psychology and sports mechanics: long jump shoes do not have a height advantage over running shoes in standing posture. If you want to achieve good results in standing long jump, you need to lean forward and fully stretch your body when taking off, complete the rapid change of flexion and extension of the legs in the air, and extend your calves forward before landing, and move forward instead of backward after landing. Only by doing this standard action every time can the design advantages of the toe and heel of long jump shoes be brought into play.

[0060] After wearing this pair of long jump shoes, students will have a strong psychological hint, which will turn the skills that were originally in theory into a driving force to achieve twice the result with half the effort. Students who originally had psychological barriers to leaning forward when taking off and extending their calves forward when landing will be more likely to overcome this fear, thus achieving the purpose of auxiliary sports teaching.

[0061] The purpose of this long jump shoe is to strengthen the correct posture, guide and strengthen the key points of long jump, and reduce the potential energy loss caused by non-professional shoes in details.

[0062] IV. Innovation and Advantages

[0063] (1) Take-off optimization design: The thickened structure at the toe compensates for the height loss caused by the forward tilt of the center of gravity and increases the airborne time.

[0064] (2) Landing optimization design: The heel-cut design prevents premature contact and enhances landing stability. (3) Comprehensive performance improvement: Adapt to the needs of athletes at all stages and improve performance.

[0065] V. Conclusion

[0066] The design combines kinematics, dynamics and mathematical analysis, and is systematically optimized for the actual needs of standing long jump athletes, and its significant effect has been verified through experiments. This shoe type significantly improves take-off and landing performance, provides professional support for standing long jump special training and competitions, and has high innovation and practical value.

[0067] The utility model relates to a training shoe made of a sole. The training shoe can provide a correct landing effect and correct a long jump action in normal training.

[0068] This product enables the user to obtain obvious results when trying to stretch the calf forward, so that the user can develop the habit of stretching the calf forward. The soles of ordinary shoes are thin in the front and thick in the back, with the center of gravity at the back, while the patented sports shoes are heavy in the front and light in the back, with the center of gravity at the front. When flexing and stretching the leg in the air, it is easier to swing the calf forward.

[0069] In the process of adapting to the patented sports shoes, if the legs are not stretched, the forefoot may step on the ground first. However, the forefoot sole is thick, and the landing will feel uncomfortable, giving the trainees a negative feedback and reminding them to stretch their calves forward.
