Description

Technical Field

[0001] The invention relates to the field of sports testing equipment, in particular to a portable and detachable weighted lunge testing equipment. Background Art

[0002] The Weighted Lunge Test (WBLT) is a closed-chain motion test that assesses the range of ankle dorsiflexion. This test helps assess the ankle dorsiflexion ability and its effect on knee movement function by observing the flexion and extension of the subject's knee under weight. At the beginning of the test, the subject stands with one foot in front of the other, with the front foot on the tape with scales, the toes pointing vertically to the wall, and the back heel touching the ground. Then, the subject gradually moves the knee forward until the knee touches the wall. The vertical distance from the big toe to the wall is recorded for each test, and the measurement is taken 3 times and the average value is taken;

[0003] Among them, the bow step, as a classic step in martial arts, fitness and various sports, originated from ancient military training and martial arts skills. In the era of cold weapons, the bow step was used to provide a strong support and force base to help soldiers maintain a stable and flexible posture in battle for attack and defense. Over time, the bow step has gradually been integrated into the various martial arts techniques and modern sports training systems, becoming a key element in improving physical strength, balance and coordination, reflecting the profound exploration and inheritance of mankind in the art of sports;

[0004] In the weighted lunge test, the tester needs to ensure that the thighs are parallel or lower than the height of the horizontal bar to determine whether the lunge sinks to the standard. By observing the correspondence between the front and back positions of the feet and the scale lines on the pedal, the stride length of the lunge is measured to judge the standardization of the lunge movement.

[0005] However, the current measurement methods have certain shortcomings. First, a high level of movement accuracy and consistency is required during the test, and individual differences among subjects (such as leg length and flexibility) may lead to deviations in the measurement results. Secondly, the calibration accuracy of the scale lines and the subject's stride adjustment may affect the accuracy of the measurement, making it difficult to fully reflect the standardized execution of the lunge movement.
