This entailed her performing a pushup with her thumbs aligned with her chin. Since she was unable to perform this, her thumbs were moved to align with her clavicle and it was reattempted. With the second attempt she was successful. This gave her a raw and final score of 2 out of 3. In order to determine the changes she should make first it will be beneficial to look at some of the muscles involved in a pushup. To name a few, the triceps brachii, coracobrachialis, pectoralis major, deltoid, rectus abdominus, and the serratus anterior are involved with this motion. The positioning of the arms in relation to the body, however, changes the size of the load placed on these different muscles. By moving the arms to a more superior position, the action of extending at the elbow is required for a greater amount of the force required to perform a pushup, thus there is a greater demand placed on the triceps brachii. If there is weakness in this muscle, the body compensates by saging in order to recruit greater involvement from stronger muscles such as the pectoralis major. Since these muscles are typically stronger it is easier to perform a pushup with the arms closer to the body. This is why Nini was able to perform the pushup in this position and not in the position with her thumbs aligned with her chin. In order to remedy this, she could work on strengthening her triceps brachii through extension exercises. An example of this would …show more content…
This entailed propping on one arm and leg on the same side while trying to touch the knee to the elbow. Since she was unable to perform this, she switched to a stance where she was propped on an opposing arm and leg. This new position enabled her to be able to touch her knee to her elbow. Moreover, she was able to complete this for both sides earning her a 2 out of 3 for both the raw and final score. When it comes to the rotary stability test, some of the major muscles involved are the rectus abdominus, external obliques, internal obliques. These play an important role in stabilizing the trunk while trying to utilize the hip flexors, shoulder extensions, and arm extensors to touch the knee to the elbow. The difficulty of this is vastly different depending on the position of the body. By propping on the same side, more core muscle involvement is needed to stabilize. In contrast, if an opposing arm and leg is used, it partially balances the body, thus decreasing the activation of the core. Since Nini, was unable to get a score of 3 some core strengthening exercises could help her achieve this. Examples of this are crunches, situps, and Russian
