Points to Ponder
The Core
Muscles can have two different roles. In one, they act to move the body (mobilizers), in the other they act to resist or control movement (stabilizers). In the core, the mobilizers can move you four main ways: bending forward, backwards, and sideways, as well as twisting.
The role of the core stabilizers is to keep the individual bones of your spine correctly aligned while using your mobilizers. This is known as Spinal or Core stability. These spinal stabilizers include the Transversus Abdominis (TVA), Multifidi and Rotatores. To make things simple, these muscles will be referred to collectively as spinal stabilizer muscles. For exercises that use spinal stabilizers, benefits will be described as “improve core stability.” Of these three stabilizers, you can most easily find you TVA muscle, and therefore know when it is working.
Sit-ups and crunches strengthen the mobilizers, but even when you finally have that washboard stomach you may still have poor spinal stability. Strong mobilizers do not give you good core stability. This is because mobilizing muscles are not attached in the correct positions to do this job, and they become tired quickly. Research shows that people with good core stability are less likely to suffer from lower back pain and injuries.
TVA?
In order to engage your TVA voluntarily and begin training it, you need to learn when it is working. Lie on your back with your knees and hips bent, feet flat on the floor. With your finger tips, find the top left and right corners of your pelvis, they should feel like hard bony points. Now slide your fingers down and inwards 2 inches. Apply pressure. You are now above your TVA muscle. To contract the TVA, hollow your lower abdomen, especially the sides. This is not as easy as it may sound. If you are having difficulty visualizing what to do or contract, try one of the prompt below.
· Imagine you have a string attached just below your belly button running through to your spine. Now pull that string towards your back bone.
· Try to pull the corners of your pelvis (the hard boney points) towards each other.
· Imagine pulling the sides of your waist away from your belt.
If you are contracting your TVA you should feel slight tension equally under your fingertips on both sides. Remember this feeling. This is what you need to do later when you read “engage your TVA”, “stabilize your trunk”, or “stabilize core”. You will use your TVA’s a lot!
If you feel the muscles bulge up, then you are trying too hard and are starting to use your mobilizing muscles. Back off a little. You need to learn to tighten the muscles with a low intensity effort. Postural and stabilizing muscles respond best to low forces. Keep practicing until you get it right!
You want to avoid tilting your pelvis, moving your back, breathing in and holding your breath. If any of these happen, then you are ‘cheating’ by using your mobilizing muscles and need more practice.
Do not worry if you have trouble doing this properly; you are not alone. Many highly trained athletes have trouble contracting their TVA properly! With repeated practice, you should be able to get your core stabilizers to contract on command.
“No Pain, No Gain?”
The old phrase”no pain, no gain” does not apply to all situations. For the most part, pain should not be experienced when performing ball exercises. Feelings of discomfort within the exercising muscle, sometimes described as ‘burning’, ‘aching’, or ‘fatigue’, may be felt. These sensations are similar to those in the stomach when doing many sit-ups, or in you quads when climbing a few flights of stairs. This discomfort is normal and acceptable.
Pains that are ‘sharp’ deep joint pains, or pain that lasts when you stop an exercise, should not be pushed through. If you cannot perform the exercise with correct technique then it is likely too advanced for you. Return to a similar, but easier exercise. NOT all exercises are suitable for everyone. We do not all have the same bodies.
If you are just starting to exercise, or trying a new technique, it is common to experience muscle soreness the following day. This soreness usually peaks on the second day and dissipates over the next few days. To minimize this soreness, start your program slowly and gradually build up the amount and difficulty of the exercises.
Strength vs. Endurance vs. Power
Strength is the amount of force a muscle can generate for a specific movement. Muscular endurance is the ability to do this movement repeatedly or for a sustained period of time. A common misconception is that training muscular strength and endurance is only for athletes. This is not true!
Both strength and endurance are of great value to each and every one of us. We use them every day when you do house-or yard-work, walk, run, lift, carry, sit, stand or any other type of recreational activities. Increased strength and endurance makes all of these tasks easier to perform. Strength and endurance also improves our posture, flexibility, personal appearance, self-image, and increases our metabolism and energy levels. Improved strength and endurance also helps prevent low back pain, decrease risk of injury, reduce body fat, enhance the ability to recover from fatigue and improve overall quality of life!
Power is defined as the rate at which a force is applied. For power, the question of speed of movement is important. The faster a given weight is moved, the more power is being exerted by the muscles. Power is an important concern for athletes and others in highly demanding sports or physical occupations.
In
order to improve your strength and endurance, your body must be challenged to
do more than usual. Tissues in the human
body adapt and improve in response to the challenges they face. If muscles are required to exert more force
than they are used to, they will adapt to this new level of activity by
increasing their endurance and strength.
This is known as the Overload Principle.
A key point to remember is that
once an exercise seems easy, your muscles have adapted and become stronger. For continued improvement, challenges need to
be increased.
The following might be called the ‘Underload Principle’! If you stop challenging your muscles, they will lose the strength and endurance they have gained.
Walking the Walk
Rest Periods: this is the amount of time taken to rest in between sets of exercise. Rest is needed between each set to allow some muscle recovery. If you do not rest, you will not be able to perform the next set effectively. Rest too long and you may not overload your muscles.(Remember the overload principle)
Tempo: This is the speed at which an exercise is performed. Tempo can range from very slow to explosive. To improve general fitness, slow and controlled movements are best. A general guideline for each rep is to take two seconds to perform the concentric phase and three seconds to do the eccentric phase. This should be considered a moderate tempo.
Muscles have to be fatigued in order for them to get stronger. Therefore, when you complete a set of any exercise, your muscles should be tired. A general guideline is that your final rep should be difficult, but still done with proper technique.

Terminology
Aerobic – Long lasting exercise done with oxygen.
Anaerobic – Short, powerful exercises done without oxygen.
Concentric contraction – A muscle contraction when the ends of the muscle are being brought to the center.
Eccentric contraction - A muscle contraction when the ends of the muscle moves away from the center.
F.I.T. Principle – F=Frequency- How often to work out. I= Intensity- How hard to work out. T= Time- How long to work out.
Isokenetic Exercises – Involves moving resistance through a range of motion on a device.
Isometric Exercises – Exercises involving no changes of the muscle length.
Muscular strength – The amount of force produced with a single muscular contraction. Having muscular strength helps decrease injuries, and improves physical conditioning.
Muscular Endurance – The capacity of a muscle or a group of muscles to continue to contract over a long period of time. Muscular endurance helps to resist muscle fatigue.
Set – A group of repetitions performed together is one set.
Repetitions – The number of times an exercise is performed.
