The hip flexion angle can be calculated by measuring the angle between the trunk and the thigh when the hip is flexed. This can be done using a goniometer, where one arm is aligned with the trunk and the other with the thigh. Alternatively, you can use a digital inclinometer or motion capture technology for more precise measurements. The angle is typically measured in degrees, with 0 degrees representing the anatomical position of the hip.

the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.
Calculate the percentage that a particular sector represents of the total value. Then the angle size is 3.6 times the percentage.
The human hip joint has three degrees of freedom. It allows for movement in multiple directions: flexion and extension (forward and backward movement), abduction and adduction (side-to-side movement), and internal and external rotation. This range of motion enables the hip to support a wide variety of activities such as walking, running, and jumping.
Hip abduction occurs in the frontal plane of motion. This movement involves the leg moving away from the midline of the body, and it is primarily facilitated by muscles such as the gluteus medius and minimus. The frontal plane is oriented perpendicular to the sagittal plane, which involves movements like flexion and extension.

The prim mover for hip flexion is the Rectus femoris. This is a quadricep muscle that crosses the hip joint.

The optimal angle for shoulder flexion to achieve a 90-degree angle is approximately 150 degrees.
The primary antagonist for hip flexion is the gluteus maximus, as it functions to extend the hip joint. Additionally, the hamstring muscles, particularly the semitendinosus, semimembranosus, and biceps femoris, also play a role in opposing hip flexion. When the hip flexors contract to lift the thigh, these muscles act to control or resist that movement.
