Sports Injury Bulletin

Sports Injury Bulletin provides workouts and exercises for building up the common musculature weaknesses that keep an athlete from maximizing his or her full potential. Identifying and fixing those weaknesses is how Sports Injury Bulletin achieved its pre-eminent statues among the sports fraternity.

The results of our advice are often astonishing, which is why SIB is subscribed to by Olympic level athletes, coaches and leading establishments such as Manchester United Football Club, The London Spine Clinic, US Olympic Committee, Commando Training Centre, The College of Traditional Acupuncture and the Ministry of Defence Medical Library.

The three-part feature on core training with give you a perfect introduction to the systematic and effective way we approach training.
The benefits of core training

The significant benefits of core training follow through to whatever you are involved in, because the area around your trunk and pelvis is where your centre of gravity is located. A strong core gives you:

Better posture
More control
Improved, more powerful performance
Injury prevention and rehabilitation
Increased protection and "bracing" for your back
A more stable centre of gravity
A more stable platform for sports movements

When you have good core stability, the muscles in your pelvis, lower back, hips and abdomen work in harmony. They provide support to your spine and help transmit increased power and performance for just about any activity.

A weak core makes you susceptible to lower back pain, poor posture and a whole host of muscle injuries. Strong core muscles provide the brace of support needed to help prevent such pain and injury -- and this discovery is why core training has become so popular among elite athletes.

How the Core Muscle Training System works from the inside out

The Core Muscle Training System has been tested on athletes at all levels and is now available for you to try out. Once into the program, you’ll find you are transmitting increased power into each movement with less effort, giving an exponential boost to your performance.

Other benefits include a toned torso and abs and a healthy and flexible lower back. Your lower ab muscles are drawn in towards the spine to help you sit up straight, improving your posture.

Core training is an intelligent training structure, because it strengthens weak muscles and imbalances from the inside out.
Endorsed by medical experts, coaches and physios

Sports medics, physiotherapists and strength and conditioning coaches recommend athletes perform regular core stability or trunk strength exercises for a very good reason: strengthening your prime movers brings more benefits than almost any other exercise both in your sporting movements and in your daily life.

Core stability exercises boost performance by building up weak areas and help to avoid a variety of injuries, especially those involving the back, groin, hamstrings and knee.

So why don’t we see more athletes doing core training? The reason most athletes skimp on this vital part bit of their workout is because the benefits are simply overlooked. There are also a number of points where guidance is needed.

Core stability training, while bestowing considerable performance advantages to most athletes, must be approached in the right way: there are a number of common pitfalls to avoid which you will need to know about before you start.

The questions you need to ask about core training, and the pitfalls to avoid

With the advent of Pilates and other core muscle exercise programs the far-reaching benefits of this kind of training has become well known. But there are some crucial questions you need to ask before embarking on your training - and some common pitfalls to avoid.

Within the repertoire of ’core stability‘ there is a large range of exercises. Which ones should you start with? How and when should you progress to the next level? What exercises should beginners avoid? And what is the major reason so many athletes and sports people fail to include a comprehensive core training program within their regular workouts?

”Teach an athlete a new core exercise and they will find it difficult, simply because it’s a new stimulus. Progression and variety are key to success."

That quote comes from the creator of the Core Muscle Training System, Raphael Brandon. As always with our key contributors, he makes good sense. What’s the point of taking delivery of a wide-ranging and effective exercise program if the athlete (that’s you) doesn’t take full advantage of it? The truth is, many workouts take up too much time, the results take too long to come through and the athlete gets bored! We explain below how Core Muscle Training System deals with that dilemma.

Athletes tend to have a list of three to five ‘core stability’ exercises targeting various muscles or positions that they are required to perform regularly each week. Whilst this ‘prehabilative’ strategy is well intentioned, it has two limitations:

Behavioural: core stability exercises can quite quickly become ‘bore stability’! It takes self-discipline to do 20-30 minutes of the same exercises three or more times a week over a long period. As you will read, adherence to the program is an issue we tackle at the outset
Physiological: the principles of specificity and progression apply to core work in the same way as they do to any other body training. It is quite common for an athlete to perform the same core routine over a long period and get very good at four or five movements or ‘holds’. But teach the same athlete a new core exercise and they will find it difficult. We explain why this is and how progression and variety are key to optimizing benefits of the strengthening program

Maximizing the muscle groups you train

The scheme of core training menus, as published in Sports Injury Bulletin, provides a system where an athlete can follow a prophylactic or rehabilitative core stability and strengthening program using a wide variety of movements.

The secret is a rotation training system based on off-the-shelf “menus”, which enable the athlete to face new challenges each week, while ensuring they are covering the necessary ground in every workout. The system also allows for progression, a cardinal principle of any successful long-term exercise regime.

This unique system offers a challenging program, covering all the trunk and pelvic muscles. It contains exercises for all athletes, running from basic recruitment to very advanced strength movements.

The training system contains 10 exercise menus, each menu using a single piece of training apparatus. A menu contains four to eight exercises, which between them target most trunk and pelvic muscles. Some of the exercises involve resistance, some bodyweight, some are simply about recruitment.

Within the menu, the difficulty of exercises varies, and some menus are very advanced.

How to use the program

Simply select the most relevant menus to be used in rotation. Thus, if you are using eight menus and doing four units of core training per week, over the course of a fortnight you will perform each menu once.

This will ensure you work all the muscles in a variety of ways, using different pieces of equipment.

The suitability of the exercises chosen will vary according to the therapeutic needs of each individual. There are three major groups:

Those focusing on the recruitment of the small deep-lying stabilizing muscles, transverses abdominis and multifidus, often taken from clinical Pilates
Static bodyweight exercises focusing on developing stability and/or strength endurance in certain postures, and requiring co-contraction of the small stabilizer and larger mobilize muscles, such as the popular ‘plank’ exercise
Traditional dynamic strength exercises for the prime movers of the trunk, often performed on the floor or Swiss ball.

You’ll find Raphael Brandon’s three-part trunk strengthening regime* is designed to sustain challenge and beat boredom. Each technique is fully explained with diagrams.

*The effectiveness of exercises contained in the program has been established by research conducted and published by McGill S (2002) Low Back Disorders Human Kinetics; Behm DG et al (2005) Journal of Strength and Conditioning Research; Konrad P et al (2001) Journal of Athletic Training; Leetun DT et al (2004) Medicine and Science in Sport and Exercise

Menu 1: floor static

The aim of Menu I is to develop a basic level of lumbar and pelvic stability working front, rear and side muscles of the trunk. It can also be used as a maintenance dose of training for intermediate to advanced level athletes. Here are the exercises:

The first exercise requires good abdominal strength and co-contraction of the abdominal wall musculature to hold the lumber spine and pelvis in correct alignment. Muscles targeted are:
Rectus abdominis
Abdominal wall (TvA/internal obliques)
This is a safe and effective exercise for the obliques and quadratus lumborum (a key lumbar stabilizing muscle). Recent research also shows this to be an excellent exercise for the lower abdominal muscles. The level is basic to intermediate, and the muscles targeted are:
Obliques (internal and external)
Quadratus lumborum
Transversus abdominis
Research suggests this is more a low back than gluteal exercise. However, it is a good way to teach athletes to recruit the gluteals in the ‘inner range’ position. The level is basic, and the muscles targeted are:
Gluteus maximus
Erector spinae/multifidus
A safe and effective exercise for the lumbar and thoracic portions of the erector spinae muscle, this exercise also requires co-contraction of the abdominal wall muscles to stabilize the pelvis. The level is basic to intermediate and the muscles targeted are:
Thoracic and lumbar portions of erector spinae

Menu 2: floor, dynamic

This menu develops a good level of strength endurance in the major trunk muscles. Overall the level of these exercises is intermediate to advanced:

The first exercise requires a strong static contraction of the abdominals to stabilize the lumbar spine against the load of the legs. It also requires good active range of motion of the hamstrings. The level is intermediate to advanced and the muscles targeted are:0
Rectus abdominis
Abdominal wall (TvA/internal obliques)
Hip flexors
If the back cannot be stabilized during this movement, the exercise is too advanced and more static transversus stability control work will be needed first.
This is a good exercise for both the obliques and the abdominals. The level is intermediate and the muscles targeted are:
Rectus abdominis
Obliques
This is an isolation exercise for gluteus medius. Strength in this muscle group has been shown to be useful in preventing lower-limb injuries in female athletes. The level is basic and the muscles targeted are:
Gluteus maximus
An advanced active mobility exercise working the obliques and trunk rotation. The level is advanced and the muscles targeted are:
Rectus abdominis
Obliques

What you receive in parts 2 and 3 of the program

Once you experience the benefits of the first part of the program, you can then decide if you wish to continue your subscription to Sports Injury Bulletin and collect parts 2 and 3 of the Core Muscle Training System (remember, the Core Muscle Training System is just one of the workouts featured in Sports Injury Bulletin. Whatever your sport or activity you’ll find it covered).

Here’s what parts 2 and 3 contain:
Menu 3: Swiss ball, static:

The four exercises in this routine challenge the athlete’s ability to hold good posture and pelvic alignment against both bodyweight and the instability of the Swiss ball. The positions of the holds are similar to the static floor exercises in Menu 1, except they are performed on the ball.

Research shows that the performance of core exercises upon the labile surface of the Swiss ball can increase the levels of trunk muscle activation; so this menu is a progression from floor-based work.
Menu 4: Swiss ball, dynamic:

These exercises are challenging to trunk strength. The use of the Swiss ball both increases the difficulty because of the instability, and allows you to work through useful ranges of movement. This menu targets the front, back and side of the trunk musculature at intermediate to advanced level.

Menu 5: Pulley machine, kneeling
Menus 6: Pulley machine, standing

Menus 5 and 6 work with the weighted pulley machine, and menus 7 and 8 use weighted ‘medicine’ balls.

All menus incorporate the need to work dynamically through the body's natural "sling" systems in order to maximise functional stability in particular in relation to rotational or torque forces. Many sporting actions require strong rotational stability both to enhance performance and guard against injury. In part 4 we wind up the series with 2 super-advanced strength building menus.

Influence of dynamic versus static core exercises on performance in field based fitness tests


Minimal evidence supports the claim that core stability training transfers into
improved performance and the most effective training method to perform core exercises is still unknown. The purpose of the study was to compare the effects of a 6 week unstable static versus unstable dynamic core training program, on field based fitness tests. A static (n Z 6) and dynamic (n Z 6) training group performed two 45 min sessions per week for six weeks.
Seven performance tests, consisting of three core (plank; double leg lowering; back extensions), one static (standing stork) and three dynamic (overhead medicine ball throw; vertical jump; 20 m sprint), were administered pre- and post training. Between group differences were assessed using a repeated measures MANOVA (P < 0.05). Both training groups improved in each of the core tests (P < 0.05). Neither training group demonstrated improvement in the dynamic field based tests (medicine ball throw, vertical jump height and 20 m sprint) (P > 0.05). Findings indicate that both types of training improved specific measures of core stability but did
not transfer into any sport-related skill.

Core stability and core strength have been subject to research since the early 1980s. Research has highlighted benefits of training these processes for people with back pain and for carrying out everyday activities. However, less research has been performed on the benefits of core training for elite athletes and how this training should be carried out to optimize sporting performance. Many elite athletes undertake core stability and core strength training as part of their training programme, despite contradictory findings and conclusions as to their efficacy. This is mainly due to the lack of a gold standard method for measuring core stability and strength when performing everyday tasks and sporting movements. A further confounding factor is that because of the differing demands on the core musculature during everyday activities (low load, slow movements) and sporting activities (high load, resisted, dynamic movements), research performed in the rehabilitation sector cannot be applied to the sporting environment and, subsequently, data regarding core training programmes and their effectiveness on sporting performance are lacking.

There are many articles in the literature that promote core training programmes and exercises for performance enhancement without providing a strong scientific rationale of their effectiveness, especially in the sporting sector. In the rehabilitation sector, improvements in lower back injuries have been reported by improving core stability. Few studies have observed any performance enhancement in sporting activities despite observing improvements in core stability and core strength following a core training programme. A clearer understanding of the roles that specific muscles have during core stability and core strength exercises would enable more functional training programmes to be implemented, which may result in a more effective transfer of these skills to actual sporting activities.

Core stability and cycling


Core stability has received considerable attention with regards to functional training in sports. Core stability provides the foundation from which power is generated in cycling. Abt, et al., (2007) determined the relationship between cycling mechanics and core stability. Hip, knee, and ankle joint kinematic and pedal force data were collected on 15 competitive cyclists while cycling untethered on a high-speed treadmill. Total frontal plane knee motion, sagittal plane knee motion, and sagittal plane ankle motion increased after the core fatigue protocol. Core fatigue resulted in altered cycling mechanics that might increase the risk of injury because the knee joint is potentially exposed to greater stress. Improved core stability and endurance could promote greater alignment of the lower extremity when riding for extended durations as the core is more resistant to fatigue (Abt, et al., 2007). McEwan, (2009) also determined the improve core strength for optimal performance and cycling injury prevention. Accordingly, the glutes, the oblique abdominals, and the back extensors are other muscles that must be working optimally to hold the form when the pressure is on.

Yoga and Core stability


Yoga is one of the trainings for core stability that has been mentioned through a few studies. For instance, the study conducted by Petrofsky and Morris (2005) demonstrated the effect of Yoga on the right and left rectus abdomens and of the right and left external oblique muscles. The “Uddhyana Bhanda” and “Nouli” are practices of Yoga that Omkar, Vishwas, and Tech (2009) applied to core stability. They also argued those practices that can affect lumber multifidus, transversus abdominis, rectus abdominis, internal obliques and external obliques muscles.

Pilates and core stability



Pilates and core stability
Julie, (2003) noted that Pilates can affect on core. His study mentioned that Pilates is a mind and body approach to fitness, including 6 basic principles such as breathing, precision, centering, flowing movement, control, and concentration. He presented several key movements and breathe patterns used in Pilates, including neutral pelvis, C-curve and spinal articulation, back muscle engagement, and abdominal muscle engagement. Making Pilates a regular part of one's fitness regimen can help achieve a longer, leaner looking physique, an increased energy and stamina, and fewer aches and pains from the stresses of everyday life. Another study conducted by Kane and Bell (2009) affirmed the effects of 6-week Pilates exercise on the 3 children, 9-11 years old. The effect of the program on motor skills, self-perceived adequacy for physical activity and balance, strength, and core stability activities was examined.

The Pilates training group improved in quickness and functional ability, both important components of lower extremity function. Pilates training can be beneficial for football linemen to increase quickness and the ability to move horizontally. Sander (2005) recognizes effect of Pilates training to increased lower extremity functional ability in Division II football players. Pilate’s exercises were shown to influence the lumbo-pelvic-hip complex, thereby leading to an increase in strength and stability.

Core exercise with Swiss ball


Researchers in their studies proclaim the effect of Swiss ball on the core stability. One study found that during biceps curls the activity in the rectus abdominis and external obliques increased (Moreside, Vera-Garcia, and McGill, 2007). Another study concluded that five weeks of Swiss ball core stability and balance exercises increased torso balance and EMG activity compared to conventional floor exercises in women (Cosio-Lima, Reynolds, winter, Paolone, and Jones, 2003).

Upper rectus abdomens and lower rectus abdomen are muscles of core area. (Duncan, 2009) investigated the effect of on and off Swiss ball exercise on those muscles. As the results of electromyography, muscle activity was greater when exercises were performed on a Swiss ball in comparison to a stable surface. Marshall and Murphy (2005) in the same study found this result as they assessed lumbo-pelvic muscle activity during different core stability exercises on and off a Swiss ball. Subjects performed four exercises on and off a Swiss ball: inclined press-up, upper body roll-out, single-leg hold, and quadruped exercise. They also found, there was a significant increase in the activation of the rectus abdominus with performance of the single-leg hold and at the top of the press-up on the Swiss ball. There was evidence to suggest that the Swiss ball provides a training stimulus for the rectus abdominus, and core stability.

Stanton, et al., (2004) examined the effect of a Swiss ball training program on core stability, VO2max, and running economy. Subjects were randomly divided into a Swiss ball group or a control group. Both groups continued to perform their normal physical training, which consisted of skills training and run-based conditioning.

Significance of core


Significance of core
Being fit in physical activity and sports helps perform skills better and prevent injuries during the performance. In recent years, there has been an increasing interest in core stability. The core stability improves coordination of lower body limbs and balance to perform better activities. For example dynamic balance is an important factor in sports and among athletes that helps them to perform activities better. In addition, core training is not difficult or time consuming and it does not require expensive equipment.

Sports and activities can be organized in many different ways. For the purpose of this blog, sports are classified in order to understand the training demand and movement pattern. It is possible to look at the muscular activity of each sport and see that certain movement skills are similar and therefore can be trained in a similar approach. Some sports are quite similar to others in pattern of movement as well as identification of muscle groups which need to be trained. Of course, some sports can be fit into more than one category.

Core training has important assistance in sport, fitness, and injury prevention. It can be one of the most successful tools for athletes and non-athletes. Core training adds variety to the traditional weight-training program. Core will strengthen posture, abdominals, back, and decrease risk of injury. Core is the center of power. A strong core will ensure efficient and effective functions of the body. All balance training is partly core strength training. From foam rollers, to balance boards, to balance balls, all balance devices involve core muscles for stabilization and develop strength as well.

A foundation of Core Stability and Balance Training presents a detailed review of the basic progressions for developing core stability. Each progression is explained and demonstrated, using a physioball, tubing, and the whole body – in a manner designed to challenge and develop static and dynamic stability, balance, and the ability to move in a functional, integrated way.

Core training reduces risk of injury since the balance is improved as well as building strong back and strong abdominals. Positive contributions of core training are seen in sport, athlete conditioning, and general fitness. In core training, well executed technique produces optimal results. Moving on ball may seem like a simple or playful concept, but it activates the body’s proprioceptive mechanism challenging the low back and deep abdominal stabilizers. Fitness professionals modify and adapt each exercise to each level of fitness to follow for exercise progression (Roetert, 2001).

According the studies (Akuthota, et al., 2008; Akuthota and Nadler, 2004; Faries and Greenwood, 2007) core stability may provide several benefits to the musculoskeletal system, from maintaining low back health to preventing knee ligament injury. For instance, the acquisition and maintenance of core stability is of great interest to physical therapists, athletic trainers, and musculoskeletal researchers. Core stability is the ability of the lumbo-pelvic hip complex to prevent buckling and to return to equilibrium after perturbation that refers to balance. Although static elements (bone and soft tissue) contribute to some degree, core stability is mainly maintained by the dynamic function of muscular elements. Core stability increase balance, strength, and functionality, helping feel better, have more energy and reduce pain for an active lifestyle. In other words, those that have good core stability also have good balance. Use this exercise program to help develop better core strength, core stability and improved balance.

Anatomy of core



Anatomy of core

The anatomy of musculature and synergies of the core is the first step to fully understanding core stabilization and its effects. The core muscles are divided into two groups: local musculature and global musculature (Akuthota, et al., 2008). Local muscles include the transverse abdominis, internal oblique, multifidus, lumbar transversospinalis, diaphragm, and pelvic floor musculature. The global muscles consist of the rectus abdominis, external oblique, erector spinae, quadtratus lumborum, adductor complex, quadriceps, hamstrings, gluteus maximus, and abductor muscles. Other muscles of the lumbo-pelvic-hip complex also contribute to the synergies and stabilization of the core, including piriformis and psoas major-iliacus complex (Donatelli, 2007).

What is the core stability?


Core stability

Kibler, et al., (2006) alleged a general definition of core stability as the ability to control the position and motion of the trunk over the pelvis and leg to allow optimum production, transfer and control of force and motion to the terminal segment in integrated kinetic chain activities. The core can be described as a muscular box with the abdominals in the front, par spinals and gluteus in the back, the diaphragm as the roof, and the pelvic floor and hip girdle musculature as the bottom (Faries and Greenwood, 2007). Core strength should be distinguished from core stability.

Core strength versus core stability

Term of core strength refers to the strength of these core muscles. Core muscle strength is usually operationally defined by a measurement of the strength of core muscles, either in terms of how much weight/resistance a muscle can lift, how many repetitions a muscle can perform, or how long a muscle can hold a neutral stable position (Faries and Greenwood, 2007).

So, "stabili­ty" describes the ability of the body to control the whole range of motion. In general, the goal of the core musculature is to stabilize the spine during functional demands, because the body wants to maximize this stability. When the term "core stability" is used, reference is being made to the stability of the spine, not the stability of the muscles them­selves (Faries and Greenwood, 2007). Measurement of core stability is more challenging to measure than core muscle strength as it requires incorporating parameters of coordination and balance. An example of testing ones core stability is a lunge. A lunge is a dynamic movement in which a large step forward bending the knee, and touching the opposite knee to the ground. The spine should maintain an erect posture, without tilting the pelvis or shoulders, the forward foot is directly under the knee, the forward leg does not deviate to either the right or the left. Accomplishing this maneuver without deviation requires the deep trunk muscles to control the spine, pelvis and hips, while lifting the body’s weight.

A more challenging example of testing core stability would be the Olympic weight lift of the “clean and jerk. This requires very strong core muscles, correct spinal alignment, while lifting a progressively heavier weight. Another example is to maintain the spine and trunk in a stable alignment while, sitting, or standing on an unstable surface such as a gym ball, or balance board while lifting weight with the arms or legs.
