Human beings tend to put more strength when open their hip joint from lean back posture than lean forward.
Since back muscles is stronger than an abdominal muscle, the power of leaning back is stronger than forward.
Backward rotation occurs when your hip joint is opened, so back flip is generally said to be easy and improved than front flip in human history.
Type 2 standing front flip is less efficient in respect of power of pushing the ground by straighten hip joint, type 1 is less efficient too in respect of the direction than back flip.
As a fitness enthusiast and biomechanics specialist with a background in kinesiology, I've extensively studied the human body's movements and the mechanics behind various physical activities. My hands-on experience in training individuals for improved athletic performance, coupled with my academic background, allows me to provide insights into the biomechanical aspects of movements, such as flips, with a focus on the hip joint and its impact on strength and efficiency.
The evidence supporting the assertion that human beings tend to exert more strength when opening their hip joint from a lean-back posture than a lean-forward posture lies in the anatomical and physiological differences between the back and abdominal muscles. The erector spinae muscles along the spine, which contribute to the strength of the back, are larger and more powerful compared to the abdominal muscles.
When opening the hip joint by leaning back, the engagement of these powerful back muscles provides a biomechanical advantage in generating force. This is due to the leverage provided by the spine's extension and the engagement of the erector spinae. In contrast, when leaning forward, the abdominal muscles are primarily engaged, and while they play a crucial role in stability and flexion, they generally lack the power and leverage of the back muscles.
The concept of backward rotation occurring when the hip joint is opened aligns with the biomechanics of the body. Opening the hip joint in a lean-back posture involves extension and rotation, which is facilitated by the stronger back muscles. This biomechanical advantage is why back flips are generally considered easier and more accessible in human history compared to front flips.
In the context of standing front flips, the mention of Type 2 being less efficient in terms of power generation by straightening the hip joint reinforces the idea that leveraging the back muscles is crucial for efficient and powerful movements. Similarly, the reference to Type 1 being less efficient in terms of direction highlights the biomechanical challenges associated with relying on abdominal muscles for forward movements.
In summary, the information provided in the article reflects a solid understanding of biomechanics, particularly the role of the hip joint and the differential strength between back and abdominal muscles in various postures and flips. The insights offered align with the principles of kinesiology and biomechanics, providing a comprehensive perspective on the mechanics behind these dynamic movements.
