A couple of weekends ago, our White Rock Lake studio was honored to host one of the two partners for some very powerful cycling and triathlon training and analysis software, David Tilbury-Davis. Mr. Davis is a triathlon coach with the British Triathlon Union (BTU), and will be relocating from his base in Spain to a new location outside of Houston this year. He came to Dallas to explain to an elite crew of coaches, what RaceDay Apollo is, and what it can do for the coach and the athlete. Read More

Quick question - what is the FOUNDATION for Power Generation in the body? Answer: THE CORE!!!! Now - WHAT THE HECK IS THE CORE?! I mean, there are SO MANY DIFFERENT ideas out there. What are we really talking about?! In a further discussion with Coach Kurt, we'll begin at, of course, THE CORE!!!! "To me, the Core is the link between Upper and Lower Body. This Link tranmsits force, back and forth. In most sports, energy is translated from the legs, through the core, to the upper body and arms. Most 'Striking' and 'Throwing' sports, as well as contact sports, are like this. For example - in a pitcher, a great pitch begins on the base plate. The foot is planted, the legs begin the windup, the energy is transmitted in to the torso as the pitcher literally becomes unbalanced, and the shoulders wind up the arms, to the point that the final extremity to touch the baseball, is literally the edge of the fingers. Imagine doing this 200x/day, for a 20 year career. It's absolutely astounding, especially when the pitcher can intuitively place the ball where he wants, and with different speeds and spins. For cycling, the exact opposite takes place. Energy and the source for high effort begin AT the core, as the body seeks a platform or foundation for stability up above and propulsion down below. The object is to get as little movement as possible in the bike, and get as much energy transmitted from the pedal platform in to the drivetrain. You're not trying to move the bike laterally, and you're not trying to over-emphasize movement in the sagittal plane of the body as well. A STABLE body is an EFFICIENT body. In a sport where literally millimeters and fractions of a second make a difference, as well as economy from an energy expenditure "angle", having a strong, stamina-related torso, will definitely translate in to more Speed, More Strength, and More Stamina. This post will be all about the abdominal muscles and how improving their performance can lead to better cycling. This is an overview of the musculature of the abdominal region in the human body. The outer layers consist of the external obliques, and the rectus abdominis. These are muscles of the outer unit of the abdominal region. The reason they are in the outer unit, is that they are large muscle groups, and are responsible for what we call "Global" stability. Think about it - the 'Guy Wires' that keep telephone poles upright, are critical to our infrastructure's daily maintenance. So, the Abdominals are critical in helping keep us upright and they're important when you're generating a lot of force. EMG's reveal that the abdominals are engaged in just about every single resistance training activity. However, it's important to note that they are engaged much more significantly when individuals are standing, versus sitting or lying. A bike, however, does not translate in to a seated position. You're still transferring force from the arms to the legs, and vice-versa. The next layer is the internal obliques, also considered an outer unit or global muscle. The final layer, and the deepest is the transverse abdominis. The transverse abdominis seen above is part of the Inner Unit, which includes the diaphragm, the muscles of the pelvic floor, and small intervertebral muscles of the lumbar spine, called 'maltifidi'. This is a circular muscle, as it wraps around the body, from back to front, above the hips and below the rib cage, almost like a girdle. When it contracts, it literally squeezes the organs and creates a smaller circumference. As you can see here, the multifidi, are attached to the vertebrae, crossing one or two each. They are responsible for 'inter-segmental stabilization' of the lumbar spine. This is a side view of the muscles of the pelvic floor. When they contract, they tend to LIFT the organs of the lower abdominal cavity upward. The diaphragm provides the 'Cap', or 'Cover' musculature for the abdominal cavity. When we take a deep, belly breath, the diaphragm pushes DOWN on the organs of the abdominal cavity. The transverse abdominis, the multifidi, the muscles of the pelvic floor, and the diaphragm, compose the 'inner unit'. The inner unit works like THIS: A deep belly breath is taken, the diaphragm expands and pushed down on the viscera. As we activate our transverse abdominis, a circular girdle is formed around the viscera, compressing it inward. The muscles of the pelvic floor, also on the same neurological loop, LIFT the viscera upward, and the multifidi, also on the same loop, activate to stabilize the lumbar spine. This creates a noncompressable "cylinder" that supports the lumbar spine, and allows for the reliable, transfer of force, between the lower body/pelvis, and the upper torso/arms. If you've ever wondered why it is that your entire 'gut' is THERE, this is the reason. NONE of this will compress, but when you perform high-force pedaling, this unit is a CRITICAL part of the pedal cycle! Now, all of this is overthinking it a bit. BUT, you HAVE to know this, in order to better apply exercises that will optimize this portion of your body. Here are a few questions for you:
- Which of the four abdominal muscles do NOT attach to the rib cage at some point?
- Which of the four abdominal muscles to NOT attach to the pelvis at some point?
- abdominal trauma or low-back trauma,
- any surgery to the abdominal or low-back area,
- a bike crash or injury to the lumbo-pelvic-hip complex,
- and even extrended, chronic gastro-intestinal disfunction (because these organs literally plug in to the same neuro-muscular 'socket').

When I started coaching twenty years ago, I was privileged to begin at a time when what we knew about performance, and what we didn't know about performance regarding cycling, left a wide gap of knowledge that needed to be filled. Fortunately, in 1996 and 1997, I returned to Dallas, where I hired a Personal Trainer, so that I could become a better mountain biker. Coach Kurt Chacon helped me understand that just because I was skinny and had a high metabolism, it did not mean I was going to be a stronger mountain biker. Texas Mountain Biking required a LOT of upper body muscular endurance and core strengthening, and over six months, Coach Kurt helped me gain about 5 lbs of muscle, which aided me towards getting several Top 10 finishes in my category in TMBRA. We forged a friendship that has now led to Coach Kurt becoming one of the Coaching Professionals at Cycling Center Dallas! This post is going to expand upon the synopsis above - in order to improve ALL of your cycling demands, you have to focus on ALL of the Physiological Requirements, and it ALL begins by assessing your body's composition and physical structure. Recently, Coach Kurt performed one of the first assessments in our newly opened Richardson Studio. The gentleman undergoing the examination was in his 60's, had about 8 years of consistent cycling experience, and had reached a plateau that he wanted to surpass. Coach Kurt followed this protocol to determine what this rider's core strengths and weaknesses were on a biomechanical level. The assessment began with the rider standing upright against a solid-colored wall, beside a plumb line. Upon observation, it became immediately noticeable that this cyclist had serious postural deviations from normal populations. Posture ALWAYS begins at the feet. The plumb line is spotted roughly between the heels. The plumb line should ideally run through the umbilicus, bisect the sternum, chin, nose and forehead. From the waist down, you can see an immediate offset between left and right. The left foot is closer to the median, and upon discussion, Coach Kurt learned that this rider placed all his weight on his left leg. Looking further up, he determined muscular differences, and upon further discussion, Coach Kurt learned that he had broken his right hip and had it pinned back together. Favoring one leg over another had led to pain and chronic arthritis in the left knee. Moving up from the pelvis, the photograph reveals a torso that is shifted to the left. The right hip is markedly higher, and the right shoulder is markedly lower. Diversion from the sternum is also much more obvious. Eyes, teeth and ears, should ideally be perpendicular to the plumb line. Obviously, his torso is shifted to the left, and his head is tilted back to the right to compensate for the left torso shift. In just this sagittal plane view, this rider definitely has needs that extend beyond "Watts". How would a bike shop fit a bicyclist with these deviations?? Good Question! Now, let's approach this client from the coronal plain.... Once again, we begin at the feet. The plumb line starts at the lateral malleolus, which is the "bump" on the outside of your ankle. Ideally, the plumb line should run through the hip joint, the shoulder joint, and right behind the earlobe. As you look at this photo, you can tell immediately that this client has shifted his entire center of gravity forward. Moving further up the frontal plane, the plumb line would ideally pass through the hip joint, and the chromium process. This individual instead, despite his perception that he is standing upright, is instead flattened in the lumbar region, is kyphotic in the thoracic region, and is body-weight forward. Unfortunately, as cyclists age, if they do not pay attention to these critical muscle groups along the back and spine, gravity has a tendency to 'win', due to positioning. Being over the handlebars is the same gravity strain as sitting over a keyboard, or driving in traffic. Musculo-skeletal diligence is required to maintain proper posture for effective propulsion, and this cyclist is already facing several form-induced performance handicaps. Looking at the lateral, upper view of the frontal plane, the plumb line would again, ideally be located just behind the ears. This individual is about 8cm or more out of the plane, and look how the head juts forward almost beyond the torso. The final part of the posture analysis comes once again from the feet. Notice that in this individual, the right leg's vastus medialis (the thick muscle that you see when you pedal from 3 to 5 o'clock on a pedal stroke), almost touches the plumb line, while the left musculature is at least 2cm lower. The right foot is again forward, and there is very little development of the rider's soleus or gatrocnemius. This implies that the rider has been literally depending on too few muscle groups to perform the work necessary to propel a bike forward. Now take a look at this image. Technically, this would be Scoliosis, but when a professional looks at the muscle imbalance and postural deviations in the trunk, one begins to think this is a Scoliosis of function rather than structure. In other words, this IS a musculo-skeletal imbalance that CAN be improved!!!! One of the most famous physio-therapists of the late 20th and early 21st centuries, Pavel Kolar, says, "You may not be able to alter morphology, but you CAN live a pain-free life." This individual has unfortunately developed a number of muscular compensations to avoid previous episodes of pain which may have resulted from his injury and rehab that did not take an athlete's perspective. In this final photo of the Posture Analysis, the viewer can really see how the right shoulder of this cyclist is below the left. The spinous processes of the lower thoracic vertebrae are visible. This is often referred to as "Naked Spine", and it reveals where the Kyphosis is the most severe. You can see Scoliosis that is concave on the right. The head is also shifted left, but tilted right. From the epicenter of the trunk, even with a scoliotic spine, some of it should be on the plumb line. The fold of the scoop of the Supra-Iliac, reveals that the right side is also higher than the left. Not shown, but revealed during the assessment, was marked deltas in stride when Coach Kurt had the individual walk. Future videos of this individual will be taken to show gait imbalances which directly translates in to pedal stroke imbalances. Finally, it was revealed that this individual suffers fatigue in one leg over the other. Can the reader guess which one? Based on this assessment and overview, it shouldn't be too difficult to determine. With all this information in hand, Coach Kurt now has the ability to compare this to range of motion in all his joints. Video analysis of this individual on a stationary trainer and performing basic functional movement assesments further revealed that, in coach-speak, this athlete was "pedaling with one leg". The imbalanced power output, combined with the significant postural deviations, leave the coaches at Cycling Center Dallas with the impression that this individual is metaphorically 'riding down the road sideways'. One might think that this assessment leaves the athlete in a dire situation or with limited prognosis for improved Stamina, Strength, and Speed. BUT, NEVER UNDERESTIMATE THE POWER OF THE BODY TO ADAPT TO NEW STIMULI AND RETURN TOWARD AN OPTIMAL STATE! This individual has agreed to multiple training sessions with Coach Kurt which will focus exclusively on joint mobilization, flexibility and target strength training. Evidence is revealing that static, traditional resistance training methods may not be the best way to enhance posture, balance, or performance. THIS is the reason that I hired Coach Kurt when I was a Bike Gypsy, and it is the same reason that his knowledge is so valuable today.
