Module 2: Core Stability: How stable is your spine and body?

WHAT WILL YOU LEARN FROM THIS MODULE? At the end of this module, you should be able to: 1. Explain the nature and benefits of core stability exercise; 2. Perform the different core stability exercises with accuracy, strength, and endurance; and 3. Rationalize the importance of determination and patience in order to achieve a toned body.

WHAT IS THIS MODULE ALL ABOUT? This module is designed for you to assess your capacity in performing physical exercises that require muscular strength and endurance. This module will inform you about the value of core stability exercises to your spine and body in general. What are core muscles? The core muscles include the abdominal, spinal, pelvic floor and hip muscles that work together to provide stability in stationary and moving positions. They act as a corset around the trunk and are important as all other movements are generated from here. What is core stability? Core stability refers to your ability to stabilize your core. Stability, in this context, should be considered as your ability to control the position and movement of your core. Thus, if you have greater core stability, you should have a greater level of control over the position and movement of any area of your body. Your body's core is frequently involved in aiding other movements of the body, such as the limbs, and it is considered that by improving core stability, your ability to perform these other movements may also be improved. If your core is stable, then the muscles of your trunk help keep your spine and body stable. This helps you stay balanced when you move. If your core muscles are strong and they contract when they should, your posture will be better.

What are the muscles involve in core stability? The major muscles involved in core stability include the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm. The minor muscles involved include thelatissimus dorsi, gluteus maximus, and trapezius. Notably, breathing, including the action of the diaphragm, can significantly influence the posture and movement of the core; this is especially apparent in relation to extreme ranges of inhalation and exhalation. On this basis, how a person is breathing may influence their ability to control their core.

What is Core Strength? Before you will understand what core strength is, you need to know about your core. The core of the body is broadly considered to be the torso where most of the movements are highly dependent. It is the whole part of your body except the legs and the arms, and a large part of your posture is determined by it. The core muscles align your spine, ribs, and pelvis to resist a specific force, whether static (force that does not change) or dynamic (with force of external resistance). Core muscles create a solid base for your body, allowing you to stay upright and stand strong on your feet. The major muscles of the core reside in the area of the belly and the mid and lower back, and peripherally include the hips, the shoulders and the neck. No matter where your motion will start, it produces a rippling effect on your body upward and downward. Example, you are hitting a shuttlecock, the motions that is necessary will either originate in your core or move through it.

The human anatomy is built to take force upon the bones and direct autonomic force in the desired direction through various joints. You can effectively manipulate the muscles in the core, like if you want a slight forward lean when you run, or efficiently move up and down hill, you need to have some control over your movement in the sagittal (back and forth) plane. If you want to limit or enhance rotation, you need to strengthen muscles that give you control in the transverse plane. Lastly, if you want to keep your balance like in a rocky terrain, you need to have strong muscles that allow you to affect desired movements in the coronal/frontal plane.

What Your Core Does? 1. The major function of your core is it acts as a stabilizer and protector of the spine. It creates stiffness that limits excessive movement as you extend, flex, and rotate. The inner core which is comprised of the diaphragm, pelvic floor, multifidi, deep cervical flexors, and transverse abdominus are engage first during movement or breathing to protect the spine. The outer core muscles. The outer core stabilizes and protects the spine but with a more defined movement functions. 2. The core also provides internal pressure to expel substances like vomit, feces, carbon-laden air etc.

16

3. It has the ability to produce force with respect to core stability, which is the ability to control the force you produce. How Will You Make Your Core Stronger? Sometimes you would focus more on the training of your core as a prime mover and in isolation doing crunches, push up, etc. this way of training will not only miss out the most important function of the core but as well as gaining better strength, more movement efficiency, and longevity of health. Having a six pack abs is only one concept of a strong core, don’t be confused of it but if you have a well defined abdominal muscles most likely you have a strong core. You will only get a strong core if you will work hard on it. Core strength exercises can be done on a mat or a carpeted floor. There are many ways to achieve it by going to the gym or by following the videos. What are the benefits of core stability exercises? Core stability may promote the following benefits: 

Improve posture



Reduce pain



Greater control of movements



Promote normal movement



Improve the efficiency of the muscles



Reduce strain on the lower back



Reduce muscle imbalance



Increase stability of the spine and pelvis



Increase muscle strength and flexibility



Improve balance and coordination



Reduce muscle spasm

What should be the proper posture? Posture is the position in which you hold your body upright against gravity while standing, sitting or lying down. Good posture involves training your body to stand, walk, sit and lie in positions where the least strain is placed on supporting muscles and ligaments during movement or weight-bearing activities. Standing Properly

Are core stability exercises limited to sit-ups and crunches?

Many people think that doing lots of sit-ups or crunches are the solution, but that is old thinking and could possibly even lead you to injury. Performing the sit-up

19

movement actually can produce “hunchback posture” when done in high volume. Crunches are most definitely not the best exercise for the core. People generally do crunches all wrong, even when done with strict and correct form. The crunch represents an unnatural and awkward movement for the human spine. Hands behind the head, cause neck muscles to tighten, resulting in a forward tilt. This causes pressure on the lumbar spine, in order to get great core strength, there is a need to build and tone many muscles in the trunk and pelvis, which include back muscles, butt muscles, stomach muscles and even chest and upper thigh muscles. Core Stability Exercises for Beginners Here’s a great little circuit that will challenge your core safely and effectively: 

Bird-dogs – 10-12 reps



Plank – 30 seconds



Side Plank – 30 seconds each side



Glute Bridge – 10–12 reps

Recover for 1 minute; repeat the circuit 2 more times

Bird Dogs

Begin on your hands and knees, with a neutral spine and a tight core.

20

In one movement, lift your left arm – bent to 90 degrees at the elbow – and your right leg off the ground. When your arm and leg are parallel to the ground, hold the position for five seconds, keeping your core and glutes strong. Slowly return to the starting position and repeat on the other side. Plank

This one is a “must” on any list of classic core strengthening exercises for beginners because it works. 

Begin on the floor, supporting your weight on your elbows, which should be directly under your shoulders. Extend your legs straight out behind you, as you press into your heels.



Tighten your core and keep your back straight. Hold this position.

21



If this is too challenging to do with your knees elevated, you can drop your knees to the floor and hold from that position, being sure to keep your core engaged. Side Plank



Lie on your side, with your weight on your right elbow, which should be aligned directly under your right shoulder, and your knees bent. Tighten your core and lift your hips off the ground. Hold this position.



Switch sides when the rep is complete. To make this more challenging, perform the plank with straight legs. Glute Bridge

Lie on your back with your knees bent and your feet flat on the floor.

22



Tighten your glutes and lift your hips off the floor.



At the highest position, there should be a straight line from your knees all the way to your shoulders. Be careful not to “crunch” your neck by shrugging your shoulders up toward your ears. Hold the contraction for five seconds before returning the to starting position.



To make this more challenging, perform the movement as described but lift your right leg off the floor when you reach the top of the bridge, keeping your glute muscles engaged. Return your rights leg to the ground and then lift your left leg. Return to the starting position.

Core Strength vs. Core Stability

ACHIEVED

SCORING

Based from your performance, rate your core stability from 15, five as the highest and one as the lowest. Explain your rating.

24

 Core stability is the ability of the core to resist an unwanted movement. Whereas, core strength can be identified as the amount of force the core can produce to perform a desired movement.  Any physical activity that requires in maintaining balance is core stability while anything that requires in resisting fatigue is called core strength.  Core stability is the ability to keep one’s posture and position stable whereas, core strength is the ability to hold a position while resisting fatigue. Signs of Poor Core Stability If you experience any of the following symptoms you may have poor core stability:       

reduced sports performance weak stomach muscles poor balance "collapsing" technique in running or landing slower times less power increased injuries, aches and pains

Back Pain Specific Core Instability
