Cholesterol and Saturated Fat: Part 1


The topic of saturated fat and cholesterol has been in the news a lot lately with "studies" saying meat is bad and eggs are bad. The first myth I want to dispel is that cholesterol is bad and that eating saturated fat and cholesterol raise cholesterol levels in the blood.

There is no such thing as "good" or "bad" cholesterol, all cholesterol is good! Yup, cholesterol is essential for our existence, is part of every cell membrane, and is the biochemical starting point for the formation of all our hormones. Two things must happen for cholesterol to have a negative effect on the body: (1) Cholesterol ends up in the coronary (and carotid) arteries and (2) Inflammation occurs which can cause an obstruction in the artery. This obstruction can deteriorate and small pieces can break off. That is when the trouble begins (A future article will talk about this process in more detail).

About 25% of our daily intake of cholesterol comes from what we eat and the remaining 75% is produced by our bodies. The body has a very complex monitoring system of cholesterol levels and makes sure that cellular cholesterol levels are maintained in a very narrow range. It is plasma cholesterol (blood) that is measured by your doctor. This measurement does not tell us where the cholesterol is going and has little to do with cellular or artery cholesterol (which is what we don't want).

So, eating cholesterol rich food may increase your plasma cholesterol in the short term, but not in the long term. My next article will discuss the importance of this blood cholesterol reading and what the relationship is to heart disease.

DOMS: Delayed Onset Muscle Soreness


DOMS - Delayed Onset Muscle Soreness. What we dread after working out and what causes many people to give up working out altogether.
Causes of DOMS
1. Eccentric muscle contractions or "negatives." For example, when you perform a biceps curl and curl the weight up, that is a concentric muscle contraction.... the muscle shortens. When you lower the weight slowly, the biceps is contracting, but it is lengthening while it contracts. When you perform lots of slow, lengthening contractions, this can cause significant post-workout soreness.
2. A brand new workout. When you perform new movments, this is stressful to the body. It is not that you are using muscles you never used, it is that you are using them in a different way. This can cause soreness.
3. Dehydration. Muscles do not like when the body is dehydrated, so drink. Use a scale before and after to learn how much you need to replace. If you happen to gain weight after working out from drinking, then back off the fluid (this is called hyponatremia - for more click here.
4. Reactive Oxygen Species. In other words the increase of free radicals is related to DOMS. What to do - LifePak or LifePak Nano!
5. Neurology. Yes, this soreness can "spread" to adjacent muscle groups via the central nervous system. That is why recovery is so important. If your movement patterns are off, then this type of soreness is much more likely to occur. Get a Functional Movement Screen!
So, why is the title of this article Overdrive? Because Overdrive is the name of the best supplement I have come across in all my years of training to combat DOMS. I have always used a recovery supplement of some type and have experimented with dozens over the years. Overdrive has been a HUGE help to me during my recovery and allowed me to get back to where I am (and their is certainly more to come).

KINESIO TAPE

Here is a great article describing the benefits of kinesio tape by Keith Jardine, D.C.
I have been taping for 6 years now and am a Certified Kinesio Taping Practitioner. It works!


Advancements in pain neurophysiology have shed light on the treatment potential of kinesiology taping and form the basis of modern education into its use. Current research documents the negative neuromuscular consequences of injuries on a patient’s recovery following musculoskeletal injuries. This has led to an increased understanding of the importance of sensorimotor stimulation for both therapeutic and rehabilitative success.
Figure A - Neuromuscular Deficits
Figure B - Applying Kinesiology Tape
What the research has shown us is that virtually all painful conditions are associated with altered neurosensory signaling between the muscles and joints affected, and the central nervous system (CNS). The clinical presentation of this is what we call neuromuscular deficits (FIGURE A). This is ultimately where injuries result in an alteration of information coming into the central nervous system and if you have altered information coming in, you will have altered information going out. Therefore, what we are attempting to do with our treatment and rehab strategies is provide the right type of afferent stimulation in order to change the efferent output in the direction of therapeutic intent. This is exactly what we achieve with the use of kinesiology tape (FIGURE B).
The altered signals experienced by the nervous system after an injury can be normalized due to the afferent stimulation of the tape on the skin. This process occurs through a combination of mechanotransduction and mechanodisruption, leading to neuroplastic changes if prolonged. When the tape is adhered to the skin’s surface, it mechanically stimulates the touch receptors. This stimulation is converted into an electrical signal through the process of mechanotransduction. The electric impulse is then sent rushing through the nervous system. Since the impulse is traveling on A-beta fibers, touch receptors, which are bigger and faster than C-fibers and pain transmitting neural pathways, the end result is the modulation or dampening of the sensation of pain. In the nervous system, as the signaling of pain diminishes, the ability of affected muscles to activate properly is restored.
Rigorous scientific testing is still needed, but anyone who has used kinesiology taping in practice will vouch for the benefits seen in clinical practice. The introduction of pre-cut, ready-to-apply applications like those offered by SpiderTech™ now make applying kinesiology taping more clinic-friendly and time-efficient. The sound understanding of the clinical relationship between a patient’s complaint and how you apply the tape underlies the importance of an educational program. The education behind the use of kinesiology tape helps the clinician understand the multitude of conditions taping can benefit and can also help explain the different ways that the same piece of tape can be applied in order to achieve a different clinical outcome.
One of the main therapeutic benefits of using kinesiology tape in practice is the ability to extend therapeutic input to the patient beyond the office walls. As an example, we can look at something as common as knee pain. With the signals of discomfort actively transmitting to the CNS, the brain will be telling the muscles supporting the knee to “turn off,” which leads to an alteration in the timing and sequence of activation and thus a loss of function. In clinical practice, after treating the area I would apply kinesiology tape and instruct the patient to leave it on for 5 days. In this case an upper knee Spider would be applied using a neuro-sensory technique (there are various techniques that are dependent on clinical objectives) resulting in a reduction in discomfort for the patient, but more importantly, a restoration toward normal motor activation. This is crucial if movements and exercise are used as a part of the treatment plan.
Different from traditional forms of tape, kinesiology tape is designed to be flexible, so it moves with the body in motion. The tape also has a very special adhesive that allows kinesiology tape to be in contact with the skin for multiple days of continuous wear without leaving any residue or skin irritation. As seen with many of the Olympic athletes in London, the tape can be worn in very vigorous physical activity as well as during water events like diving.

The advent of kinesiology taping provides patients, whether athletic or not, an opportunity to “wear their therapy” whether demanding the most out of their bodies or simply trying to get through their day.
