CORE ASSESSMENT 2

The Sahrmann core stabilizing test (Stanton, Reaburn, and Humphries 2004) requires participants to lie in a supine position with the knees bent and the feet flat on the floor. A pressure biofeedback unit (PBU) is placed under the lower back of the participant, and the PBU is inflated to a pressure of 40 mmHg. The participant is then  required to complete a series of leg-lifting exercises while not changing the pressure in the cuff by more than 100 mm Hg. A reading greater or less than 100 mm Hg indicates a loss of lumbopelvic stability.

Another means of core assessment was established by Liemohn and colleagues. Similar to Sahrmann, Liemohn and colleagues (Liemohn et al. 2010; Liemohn, Baumgartner, and Gagnon 2005) measured core stability while participants raised one or more limbs into the air. However, they required participants to be in a kneeling, quadruped, or bridge position on a type of wobble board. For periods of 30 seconds, participants would have to maintain balance while alternately raising an arm in time with a metronome set at either 40 or 60 beats per minute. Any deviation in balance outside a 10-degree arc (+- 5 degrees from center) was recorded in seconds for the total time the participants was out of balance.


Sahrmann core stability test consist of:
·  Level 1: slowly raise one leg to a position of 100 degrees of a hip flexion with comfortable knee flexion, and then lower the leg to the initial position. Repeat the sequence on the opposite leg.
·  Level 2: Slowly raise one leg to a position of 100 degrees of a hip flexion with comfortable knee flexion. Slowly lower the leg such that the heel contacts the ground. Then extend to the leg and return to the start position. Repeat the sequence on the opposite leg.
·  Level 3: Slowly raise on leg to a start position of 100 degrees of hip flexion with comfortable knee flexion. Slowly lower one leg such that the heel reaches 12 cm above the ground. Then extend the leg and return to the start position. Repeat the sequence on the opposite leg.
·  Level 4: Slowly raise both legs to a position of 100 degrees of hip flexion with comfortable knee flexion. Slowly lower both legs such that the heels contact the ground. Then extend both legs and return to the start position.
·   Level 5: Slowly raise both legs to a position of 100 degrees of hip flexion with comfortable knee flexion. Slowly lower both legs such that the heels reach 12 cm above the ground. Then extend both legs and return to the start position.

WHAT IS THE CORE??

Imagen
Nowadays there is a confusion about understanding what goes wrong with ‘the core’ is. Its definition has been commonly discussed in the popular media and professional journals for the past decade or more.  However, the precise definition of core is tenuous, with multiple meanings, depending on the interpretation of the literature (Behm, Drinkwater, Willardson, & Cowley, 2010). Among all definitions, the one that we have found which is the most complete is: “the core can be described as a muscular box with the abdominals in the front, paraspinals and gluteals in the back, the diaphragm as the roof, and the pelvic floor and hip girdle musculature as the bottom. Within this box are 29 pairs of muscles that help to stabilize the spine, pelvis, and kinetic chain during functional movements”  (Akuthota, Ferreiro, Moore, & Fredericson, 2008).

CORE ASSESSMENT 3: CORE MUSCLE POWER

Imagen
Test that have focused on core power have utilized some type of medicine ball throw (Shinkle et al. 2012; Cowley and Swensen 2008). Shinkle et al. completed a series of static and dynamic medicine ball throws from a seated position on a bench. Four throws were completed: - A forward throw (figure a) - A backward throw (figure b) - Lateral throws to the right and left to the left (figure c) Using a 6-pound (2,7 kg.) medicine ball. The upper body was held stationary for the static throws, preventing the core muscles from contributing to the throw. For the dynamic throws, the upper body was free to move, allowing contribution of the core muscles. The feet were not secured during any of the throws. Maximum distance for each throw was recorded. Differences between the static and dynamic throws were believed to be due to the core’s contribution.

PLANK REGRESSION

Imagen
In this publication, I continued talking about the regression of plank. In the previous publication we talked about the regression in wall and in floor-high surface. In this publication we are going to focus on the regression in the floor. 3. FLOOR: Execute a plank with both knees and palms resting on the floor (elbows extended). Execute a plank without knees supported on the floor (legs extended) and palms resting on the floor (elbows extended). Execute a plank with supporting knees on the floor and resting forearms on the floor (elbows flexed). Execute a plank without supporting knees (legs extended) and forearms supported (elbows flexed). This regression is one of many that may exist. As I mentioned in previous publications, the abdominal plank is a very complete and very complex exercise. This means that if it is not executed correctly, injuries will be caused. For people who have not exercised the abdomen, this regression would...
