The correct starting posture
The correct starting position varied from person to person, depending on the athlete's strength level and body characteristics. Generally speaking, starting positions included squatting and standing. The squatting starting position was suitable for professional athletes or sprinting competitions, and it required the assistance of a starting block. In the squatting start, the athlete should maintain a stable and flexible posture, with his knees slightly bent, toes shoulder-width apart, and focus on getting ready to start at any time. The standing starting position was suitable for other athletes or ordinary competitions. It did not require a starting block. In the standing start, the athlete should place both feet on the ground, the hind legs on the knees, the front legs bent, the hands behind the starting line, the head lowered and still, waiting for the subsequent command. In general, the key to starting posture was to maintain balance, shift the center of gravity forward, focus, and react quickly.
The correct starting posture for sprinting
There were several different ways to start a sprint. There were two common starting positions: the squatting start and the standing start. Squatting start was to step on the pedal with both feet, put your hands on the ground, and squat on the ground to prepare for the start of the race before hearing the start signal. When he heard the start signal, he immediately stepped off the pedal with his back foot and swung his arms forward. The standing start was to bend your knees, lean your upper body forward slightly, and move your center of gravity forward. The starting position should be adjusted according to the individual's physical condition and strength level. There was no fixed starting position, but one could find a suitable position according to one's training and feelings.
The correct starting posture of squatting
The correct posture for a crouching start was to step on the starting block with both feet in turn. The toes of the feet should touch the ground, and the knees should be on the ground when retreating. Usually, the strong legs should be placed in front of the starting block. At the same time, both hands should be retracted to the starting line, shoulder width, straight arm support, four fingers together and thumb into a "V" shape support.
The correct starting posture for long-distance running
The correct starting position for long-distance running was to lean forward slightly and not lean back. Leaning forward was not bending his waist, but relaxing and straightening his entire torso. This posture helped to increase his running speed.
The correct starting posture for long-distance running
The correct starting position for a long-distance run was to keep your body upright, tilt your head slightly forward, and look forward. This posture could reduce air resistance and increase running efficiency. At the same time, keeping the body upright could also reduce the impact on the joints and reduce the risk of injury.
The correct posture of sitting posture
The main points of correct sitting posture were as follows: 1. ** Equal ischial stress **: First find the ischial node, which is the main stress when sitting down. Make sure that the ischial stress on both sides is consistent and avoid leaning to one side. 2. ** Position of hip and knee joint **: The knee joint and hip joint should be at a 90-degree right angle. The feet should be flat on the ground. The angle of the legs spread varies from person to person, but do not buckle too much inside or outside. It is best to have the feet as wide as the shoulders. 3. ** Spine curve maintenance **: Maintain an upright posture, straighten your waist as far as possible, slightly curve your chest, slightly retract your chin when you raise your head, and adjust the position of the computer screen according to the direction of your gaze to prevent bad movements such as leaning forward and lowering your head. 4. ** body vertical line alignment **: In an ideal state, the ears should be aligned with the shoulders and the shoulders should be lowered so that the head, shoulders, and buttocks are in a vertical line. This will help reduce the tension in the shoulders and relieve the shoulder soreness and back pain caused by sitting for too long. In addition, the simple sitting posture of "sticking out your chest and raising your head" was relatively good, but it was not completely ideal. From the perspective of disc pressure, when the back and knees were sitting at a 90° angle, the lumbar disc pressure could reach 140%. When the back was slightly tilted back to 110°, the disc pressure was even smaller, and when the back was hunched forward, the disc pressure was the greatest. From a muscle point of view, whether it was leaning forward, standing upright, or leaning back, muscle fatigue was inevitable for a long time. Therefore, the best way was to change your sitting position frequently and get up every hour to avoid maintaining the same sitting position for a long time. At the same time, when choosing a seat, you should try to choose a chair that has support, height adjustment, and tilt angle, so that the body can lean on the back of the chair to fit the natural bending of the waist.(For example, wooden chairs, hard plastic chairs), waist pads and cushions can be added to make the waist and buttocks evenly stressed; When the height of the table and chair is not suitable, resulting in the feet not being able to touch the ground, foot pads can be used; When the display screen or laptop is in a low position, a stand can be used to raise and put the screen far away, and an independent keyboard and mouse can be used to protect the cervical spine and eye health.
