Analysis of qualification standards for parallel bar arm flexion and extension

　　Parallel bar dips and extensions are a classic bodyweight training exercise that can effectively exercise Chest muscles, triceps and other parts. Understanding its qualification standards can help us standardize movements, improve training effects and prevent injuries. The following is a detailed introduction to the qualification standards for parallel bar arm flexion and extension.

action specifications

　　starting position: Hold the parallel bars with both hands, straighten your arms to support your body, keep your shoulders stable, tighten your core, and keep your legs straight or crossed. Lean forward slightly, pushing your chest forward.

　　descending stage: Slowly lower your body, control the range of movement, and keep your chest as close to the parallel bars as possible. During this process, the elbows should be kept at a certain angle to avoid excessive abduction while maintaining shoulder stability.

　　rising stage: Using the strength of your chest and triceps brachii, push your body up to the starting position. When pushing up, pay attention to the order of exerting force. First activate the chest muscles, and then activate the triceps brachii to maintain the smoothness of the movement.

muscle involvement

　　Chest training: Parallel bar dips are an effective exercise for training the chest muscles, especially the lower chest. During the movement, you should feel the contraction and stretching of the chest muscles to ensure that the chest muscles are fully involved in the movement.

　　triceps brachii: The triceps brachii play an important role in pushing up the body. When training, pay attention to the force of the triceps brachii and increase its strength by controlling the movements.

　　shoulder stability: The shoulders play a stabilizing role in parallel bar arm flexion and extension. Keeping your shoulders stable can prevent shoulder injuries while improving the quality of your movements.

breathing rhythm

　　Descending inspiration: During the descent, inhale slowly to fill your lungs with air and provide adequate oxygen to your muscles.

　　Exhale rising: During the ascending phase, exhale forcefully to expel the waste gas from the body, and at the same time cooperate with the exertion of the muscles.

Injury prevention

　　Warm up preparation: Before doing parallel bar arm extensions, you should perform adequate warm-up exercises, such as moving your shoulders, elbows and other joints, and stretching related muscles to reduce the risk of injury.

　　motion control: Control the speed and amplitude of movements and avoid excessive force or violent movements. During the movement, keep the body stable and avoid shaking.

　　progressive loading: As your training level improves, gradually increase the difficulty and load of training, but avoid sudden increases in weight to avoid injury.

Strength Testing and Assessment

　　National exercise standards: You can refer to relevant national exercise standards to understand the qualification indicators for parallel bar arm flexion and extension for different age groups and genders.

　　self assessment: By recording the number and quality of parallel bar dips and extensions you complete, you can conduct self-evaluation to understand your strength level and progress.

　　The parallel bar dip is a compound movement that exercises multiple muscle groups. Qualified parallel bar arm flexion and extension can not only reflect the strength level of the trainer, but also ensure the safety and effectiveness of the training.
