[0019] To better understand the technical solution of this utility model, the embodiments provided by this utility model are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, this embodiment provides a running aid, including: a foot strap 1, a rear straight strap 2, and a front cross strap 3. The foot strap 1 is fixed below the rear straight strap 2, and the front cross strap 3 is fixed on the rear straight strap 2 with at least one fixing point.

[0021] In this embodiment, the foot strap 1 is used to fix the foot, the rear straight strap 2 is set close to the muscles on the back of the calf, and the front cross strap 3 wraps tightly around the muscles on the side of the calf and is fixed opposite to the front of the calf. During running, the foot strap 1 stores energy when the foot touches the ground and, during the support phase, resists the expansion of the foot through tensile force, thereby shortening the foot's contact time with the ground. During the push-off phase, the rear straight strap 2 releases the energy stored by the foot strap 1 in inhibiting muscle expansion upon foot contact, assisting in the calf's ascent. The front cross strap 3 releases the energy stored by resisting the expansion of the muscles and tendons on the side of the calf through tensile force, further increasing running speed. Ultimately, this achieves the collection of non-forward energy during running to assist in forward movement and increase speed. The above structures cooperate with each other in each movement cycle to reduce the body's energy consumption during running and increase speed.

[0022] In this embodiment, the foot strap 1, the rear straight strap 2, and the front cross strap 3 are preferably provided with a latex core and polyester fiber, thereby making the product more elastic, improving the elasticity of the rear straight strap 2 which fits tightly against the calf muscles, improving the lifting force and comfort of the calf during exercise, further inhibiting the expansion of the calf muscles, and releasing the energy collected in inhibiting calf expansion during the contraction of the calf muscles, thereby achieving a more comfortable reduction in running energy consumption and an increase in exercise speed.

[0023] In this embodiment, the running aid is preferably placed on two mirrors that are symmetrical on the left and right sides to improve balance while running.

[0024] In this embodiment, when the user runs with a heart rate ≤160 bpm, the corrected pace can be increased by ≥12%. The corrected pace is calculated according to the formula `P_c=P_m×[1+0.05×(HR_d-HR_b)]` (P_m: measured pace, HR_d: heart rate during device use, HR_b: baseline heart rate).

[0025] The steps for verifying running performance are as follows:

[0026] 1. Obtain baseline data (pace P_b, heart rate HR_b) of users running on the same route without equipment;

[0027] 2. Obtain measured data (pace P_m, heart rate HR_d) after wearing the device;

[0028] 3. Calculate the corrected pace increase: `ΔP={P_m×[1+0.05×(HR_d-HR_b)]-

[0029] P_b} / P_b×100%`;

[0030] 4. When ΔP ≥ 10%, a performance certification signal is generated.

[0031] The specific verification process:

[0032] Based on real-world testing by users in the same environment (same route in Leeds, UK):

[0033] 8.65km travel time 61:39:00 47:45:00 ↓22.3％ p<0.001 Equivalent pace 7:08 min / km 5:32min / km ↑27％ Correcting pace 7:08 min / km 6:22min / km ↑12.1％ Heart rate model

[0034] Significance test based on time data (t = 8.24, df = 1)

[0035] Correction formula: Equivalent pace = Measured pace × (1 + 0.05·ΔHR)` (Wilmore & Costill, 2004)

[0036] The final result showed a 10.5% reduction in calorie consumption (537kcal vs 600kcal), demonstrating a reduction in ineffective energy expenditure.

[0037] In Embodiment 2, the front cross strap 3 includes an upper lifting portion 31 and a front cross portion 32. The upper lifting portion 31 is preferably arranged in a ring shape and is fitted onto the lower part of the thigh during use to improve the fit between the thigh and calf. The front cross portion 32 preferably starts from the rear straight strap 2, crosses over the front side, wraps back downwards, and is fixed to the rear straight strap 2. This allows it to further tighten the muscles on the side of the calf during exercise, increasing the tensile strength of the product as it moves with the body, thereby improving the user experience.

[0038] Furthermore, based on the above embodiments, the foot strap 1 includes a foot loop strap 11 and a bottom strap 12. The foot loop strap 11 is configured with a preload of 8-12N. The foot loop strap 11 can be fitted onto the foot, and the bottom strap 12 is used to fix the relative position of the foot loop strap 11 and the rear straight strap 2. Thus, during exercise, the rear straight strap 2 drives the bottom strap 12, which in turn drives the stretching of the foot loop strap 11, achieving a lifting effect and improving the user's exercise performance.

[0039] Based on the above embodiments, a further embodiment includes a side strap 4, which is disposed on the rear straight strap 2 and / or the front cross strap 3. The side strap 4 is used to protect the muscles on the outside of the calf and has a lifting effect when the user turns, thereby improving the stability of the ankle muscles, thus improving exercise efficiency and preventing ankle sprains.

[0040] Based on the above embodiments, the side band 4 further includes an outer band 41 and an inner band 42, thereby protecting muscles on both sides and improving the lifting effect of the product, thus enhancing the user experience. Specifically, the outer band 41 is used to resist and inhibit foot eversion during the support phase by expanding itself, further reducing exercise energy consumption while improving the safety factor of exercise. The inner band 42 is used to accelerate foot inversion during the push-off phase by contracting itself, thereby increasing exercise speed.

[0041] Building upon the aforementioned embodiments, the rear straight band 2 further includes a latex core with a modulus of 0.8-1.2 MPa, and is positioned along the Achilles tendon. The latex core enhances the elasticity of the rear straight band 2, which closely adheres to the calf muscles, thereby increasing the lifting force and comfort of the calf during exercise. The latex core's modulus of 0.8-1.2 MPa allows for maximum lifting effect while maintaining optimal comfort due to its small thickness. Furthermore, the rear straight band 2's alignment with the Achilles tendon further improves the product's comfort and lifting effect.

[0042] The above provides a detailed description of a running aid provided by the embodiments of this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
