Abstract
Description
A sports physical training device Technical Field
[0001] This invention belongs to the field of physical training equipment technology, specifically relating to a sports physical training device. Background Technology
[0002] Physical fitness is the basic motor ability of the human body, manifested through qualities such as strength, speed, endurance, coordination, flexibility, and agility. It is a crucial component of an athlete's competitive ability. The level of physical fitness is closely related to the morphological and functional characteristics of the human body, and the degree to which these physical attributes develop varies at different stages of human development. Students are in a period of rapid physical growth; training not only improves their physical fitness but also allows them to continuously push their physical limits, laying a solid foundation for future training.
[0003] When physical education students conduct physical training, they generally use weighted running by dragging rubber tires or strapping sandbags to their legs. Since sandbags directly impact the body, they can negatively affect the development of the students' lower limbs. Most students use weighted running by dragging rubber tires for physical training. The friction between the rubber tires and the ground not only increases stable load-bearing capacity but also provides durability and resistance to damage, allowing for prolonged training. Weighted running by dragging rubber tires involves connecting one end of a traction rope to the rubber tire, looping the other end over the trainee's shoulder, then around the waist, and securing the rope before dragging the tire forward. However, due to differences in height, the angle of the traction rope between the rubber tire and the trainee's shoulder varies. Taller trainees require a longer traction rope between their shoulder and the rubber tire; otherwise, the front of the rubber tire may not make contact with the ground, failing to provide stable load, resulting in unsatisfactory training effects and significant discomfort.
[0004] Currently, when physical education students use weighted running with rubber tires for physical training, they need to adjust the length of the traction rope according to their own height to ensure both the effectiveness of the training and comfort. For beginners, this requires a significant amount of time for length adjustment, greatly reducing the efficiency of physical training. Summary of the Invention

[0014] Compared with existing technologies, the sports physical training device provided by this invention, through the coordinated use of a support rod, a rotating shaft, a reel, and a traction rope on a rubber tire, not only facilitates physical education students to move the rubber tire for physical training, but also limits the rotating shaft with a first connecting rod. When the distance between the traction rope and the shoulder is short, the traction rope lifts the front side of the rubber tire upward, causing the first connecting rod to release and limit the rotating shaft. After the traction rope on the reel is automatically released to a suitable length, the front side of the rubber tire re-contacts the ground under its own weight and locks the rotating shaft. This avoids beginners spending a lot of time adjusting the length of the traction rope, improving the efficiency of physical training. The physical training equipment of this invention is easy to use, has good training effects, and is highly practical, making it worthy of promotion. Attached Figure Description
