Speed Training with Nick Sorensen

By James Walker CCS, STM, BioSig, Master Trainer

Nick Sorensen trained with AE most of his 10 year NFL career during his off seasons, beginning in June of 2002, after being drafted and released by the Miami Dolphins. That first year we worked with him for five and a half weeks prior to the pre-season camp.

After the initial assessment, we focused on improving his explosiveness, lean muscle mass, his lower core function, flexibility, sprint technique, and reminding him of the correlation between all of those things and his speed. In addition, we addressed his scar tissue needs, in the shoulders, rotator cuff, and lower legs, which inhibited muscle recruitment and performance, along with a few structural balance issues.

Nick never had an issue with body-fat ratios or fat composition, due to clean-healthy eating habits, even in the off season his body-fat was in the 6% and during the season 4%. When Nick began, his best forty-yard time was 4.41 seconds, when he left for camp his best time was 4.35 seconds.

In 2003 we wanted to make him completely healthy, muscular, and strong from the previous season's injuries. By camp with the Jaguars Nick was performing 135 lb dips, 50 lb close grip pull-ups, and 225 jerk presses, all for 3 reps. Likewise his sprinting technique was superb, with excellent angles, tempos, power, and limb placement. His best 40-yard times were 4.28 and 4.23 seconds.

In 2004 we started early as well, working around an elbow injury that he sustained at the end of the 2003 season. Although his time with us was limited due to team obligations and constraints but our goal was to increase his lean muscle mass, strength, explosiveness, over all flexibility, and muscle balance.

During the remainder of his career we worked with Nick through and around injuries to the elbow, shoulder, and lower leg, team off-season training restrictions, releases, transitions, and new team auditions. We would try and maintain all his performance qualities, muscle mass, strength, speed, power, range of motion, structural balance, scar tissue, and any minor injury concerns.

Through it all he learned to be proactive, disciplined, consistent, informed, healthier, and prepared in all phases of his self-care. Nick has been one of the fastest players on each of his teams, the Rams, Jaguars, Browns, and in the NFL. He maintained his 4.2s speed, until his retirement as a result of a neck injury in 2010.

What’s Up, Albert & The 300yd Shuttle?

By James Walker, CCS, STM, BioSig, Master Trainer

In this day and age of technology (cell phones, ipods, laptops, aps, internet, google, etc) that makes gathering information very accessible it’s amazing that so much incorrect and ignorant information permeates the airwaves, internet, and newsprint spheres. And this comes from journalist or in this case sports journalists who we used to rely on for accurate information! Especially since correct and reliable information is only a phone call or keystroke away.

There are countless university exercise science professors and sports-performance-strength coaches, all eagerly ready to be interviewed by some famous sports journalist concerning Albert Haynesworth’s struggle in the 300-yard shuttle. Why can’t he pass it or how should he have prepared in order to pass the easy or hard, depending on the commentator, 300 yd-shuttle test. “He needs more cardio”, “why didn’t his trainer prepare him”, “why didn’t he lose weight”, oh yeah he did lose weight, about 35 lb, “so why didn’t he pass”, or “just because he lost weight doesn’t mean he’s in football shape”, right?

I know all of my former professors, strength coaches, and exercise specialist who have mentored me the past 30 years cringe every time they hear, read, or see the responses from all of the media experts.

The 300-yard shuttle run consists of sprinting 25-yards down and back six times touching the line with the foot in order to complete 300 yards total distance. The times may range from 56 seconds for football receivers and defensive backs to 73 seconds for offensive and defensive linemen. After completion the participant rests 3-5 minutes (3 & ½ for the NFL Washington Redskins) then repeats the test a second time. The times can then be averaged or compared to determine the athlete’s fitness level.

The purpose of the 300-yard shuttle run is to test maximal anaerobic-sprint endurance and/or conditioning. In order to attain a reliable score the participant must sprint at maximum effort and not pace themselves. The general testing populations are sports that involve anaerobic-sprint endurance like-.basketball, hockey, rugby, and soccer.

Now I must confess that when I had to take Testing and Measurement and Statistics decades ago I thought I’d never use any of it but I’ve consistently relied on and utilized the information over and over, especially administering performance assessments and analyzing training data.

All test must be valid, reliable, and objective, all interrelated values and that the measurement must measure the component that it supposed to measure; measure the component consistently; and result in similar scores regardless of the administer.

Let’s look at a quick review of those terms valid, reliable, and objective.

Test validity refers to the degree to which the test measures a specific component that it is intended to measure. The test should contain tasks that reflect those specific components to be measured or it’s content validity.

Test reliability refers to the degree to which the test yields consistent and stable scores over repeated trials and time. Reliability depends upon how strict the test is conducted and how motivated the participant is to perform the test.

Test objectivity refers to the degree to which the test can be measured repeatedly and reliably by various testers with minimum subjectivity.

So in spite of how you may feel about Albert and his conditioning it’s amazing that this test is used to test football players, yet alone a 300 lb lineman. Considering that the average play last between 4-5 seconds, why would you test something that last 50-70 seconds? Does this sound valid, reliable, or objective?

First of all, 4-5 seconds of maximal effort utilize absolute strength, power, and speed, all anaerobic bio-components that involve IIB fast-twitch muscle fibers and alactic-glycolytic energy systems.

Secondly, 56-73 seconds of maximal effort (actually slightly sub-maximal) utilize strength and speed endurance that involves IIA fast-twitch muscle fibers and lactic-glycolytic energy systems. The two are very different in their respective functions and actions.

Thirdly, there is another sub-maximal speed endurance IIA fiber that utilizes a glycolytic-oxidative energy system.

Fourthly, none of these are aerobic which starts to kick in after several minutes of continuous sub-maximal effort that involve slow–twitch IA muscle fibers and primarily an oxidative energy system.

In the exercise science community it really doesn’t make since. So when these experts see test such as the 300-yard shuttle or parts of the NFL combine test they cringe, shake their heads, and wonder if any of them ever picks up an exercise science journal or text.

In summary the test is not a very good indicator of anaerobic alactic power required for football. It does not make sense to any knowledgeable exercise scientist. A better test for football conditioning would involve maximal efforts of 4-5 second that are repeated numerous times with 15-30 seconds of recovery to simulate the huddle. Watch the game, doesn’t that make more since?

Training Principles, Part Seven - Basic Sprint Mechanics

By James Walker CCS, STM, BioSig, Master Trainer

 If you’re not blessed to have a biomechanics coach or fortunate enough to work with a competent sprint coach, no one explains or teaches you correct sprint mechanics. Even having a speed & conditioning coach you may not receive the technical or biomechanical information necessary to improve sprinting. Instead you may get an over indulgence of volume running or gimmick training. I’m not suggesting that some devices can’t enhance your speed but they should be a supplement to proper mechanics, structural integrity, muscle fiber recruitment, and overall strength. Here are the basics of sprinting.

1. Sprint Running Mechanics – to run at a fast pace that requires a high or intense neuromuscular effort. The basics of sprinting can be summed up into three phases - start phase, drive phase, and acceleration phase.

a) Start Phase - may be from a two, three, or four point stance, requiring strength and power to over come inertia. Below is a checklist of proper mechanics:

·      Head position-should be down with chin near the collar and neck relaxed.

·      Torso position-(two & three point stances) should be achieved with the hips being higher than the head or hips raised with the shoulders slightly forward of the hands.

·      Arm & hand position-finger tips or hands should be on the line (in a four point stance) or the opposite side hand to the front foot (in a three point stance) with the other arm extended back slightly higher than the hips.

·      Leg & feet position-should be determined by the feet position close (bunched), medium, or elongated. The front foot should be approximately one foots length from the start line with a 90 degree knee angle, while the back foot should be positioned to allow a 120 degree knee angle (this is also the stronger and/or more coordinated leg. Both heels are raised with the front bearing the most weight.

b) Drive Phase - coming out of the start to over come inertia from the stationary position or stance to achieve a 45-degree body lean angle.

·      Head position-should be looking down at the ground but relaxed (the head position dictates the body or torso position).

·      Torso position-should be 45 degree lean angle.

·      Arm & hand position-should be relaxed with a 90 degree angle at the elbow and strong powerful alternating elbow drive to the rear on the backswing.

·      Leg & feet position-feet should be dorsiflexed (toes and ankles pulled up toward the shins) with the ball of the foot (forefoot) striking the ground behind the hips. The legs should drive down toward the ground in a powerful motion (like auto pistons or punching the heavy bag) after the heel is pulled up into the hamstring area (this actually precedes the leg drive). Tighter knee angle and knee lift equals greater striking force. The first few foot strike are critical, they must be powerful and explosive (importance of leg, hip, back, & core strength).

c) Acceleration Phase - post drive phase to reach the maximum running speedwith a 70 degree body lean angle.

·      Head position-should be neutral with the chin level to the ground but relaxed (the head position dictates the body or torso position).

·      Torso position-should be 70 degree lean angle.

·      Arm & hand position-should be relaxed with a 90 degree angle at the elbow and strong powerful alternating elbow drive to the rear on the backswing. The hand or fist should automatically return into the front-swing but only to shoulder level.

·      Leg & feet position-feet should be dorsiflexed (toes and ankles pulled up toward the shins) with the ball of the foot (forefoot) striking the ground under the hips. The legs should drive down toward the ground in a powerful drive motion (focus on striking the ground under the hips) after the heel is pulled up into the hamstring area, which facilitates knee lift or a tight knee angle (this actually precedes the leg drive). Tighter knee angle and knee lift equals greater striking force.

Training Principles, Part Five - Principles Of Exercise Science Con’t

By James Walker CCS, STM, BioSig, Master Trainer

Training principles of exercise science con’t…

16. Reps and Sets Relationship – reps and sets have an inverse relationship, fewer reps require more sets while more reps require fewer sets.

·      In part this based on the motor learning principle of “repeated effort”- when learning a new skill, task, or lesson the more times it is repeated the easier it is to remember or to perform.

·      Consequently this “repeated effort” or practice will increase the number of times that the particular muscle fiber type and its corresponding energy system gets used thereby making future efforts easier and the muscle more conditioned.

·      e.g., motor skill of riding a bike or learning a different language or exercise, the more the effort is repeated the greater the learning capacity.

17. Super Compensation – the amount of time required for the body to fully recover from the previous workout or workouts.

·      There should be full recovery prior to repeating the same muscle workout for the best gains.

·      This will result in strength increases of 1-2% or by 1-2 repetitions each week.

·      Optimal increases will not occur with out the proper rest, recovery, and regeneration.

                                                                                                                                                                                                                              18. Technique and Posture – proper form and posture are necessary for correct muscle recruitment and optimal strength gains.

·      If a movement cannot be performed with the correct technique, form, and posture it should be stopped.

·      An assessment should be made to determine the reason, so that the necessary corrections can be made.

·      Remember correct technique and posture will optimize neural drive to the correct muscles and will prevent faulty muscle recruitment patterns.

·      E.g., excessive forward lean vs. upright torso in the squat, or treadmill vs. running outside.

19. Tempo-is the pace, rhythm, and time required for each repetition.

·      Planned tempo use will ensure correct muscle fiber and energy system recruitment, and will reduce injury and faulty motor patterns.

·      Tempo is usually expressed in counts e.g., 302, 301, 30X or 402, 401, 40X, or 502, 501, 50X, that are normal but may be 31X, 512, 911 counts.

·      The first number represents the negative (eccentric) phase of the rep, usually expressed in a 2-9 range.

·      The second number usually represents the midway point, usually expressed in a 0-2 range.

·      The last number represents the positive (concentric) phase, usually expressed in a X-2 range.

·      e.g., a 302 tempo for an arm curl, starting position at the bottom with the weight in front of thigh, a 2 count is performed while the weight is curled up to the shoulders, a 0 pause at the top or midway position,  a 3 count is done while lowering the weight to the start.

Training Principles, Part Three -Principles Of Exercise Science Con’t

7. Muscle Balance – each muscle action or group has an opposite muscle action or group (agonist vs. antagonist).

·      e.g. triceps vs. biceps, must maintain a mutual balance in strength and flexibility to function properly.

·      In performance activity the antagonist muscles may act as a brake to slow down acceleration e.g. the elbow flexors act as a brake to the elbow extensors in a punch, so they need to be strong to perform this task.

·      Demonstrate-a throw or punch or sprint.

8. Muscle Fiber Type and Energy System – there are two basic muscle fiber types, slow twitch (IA) and fast twitch (IIAo, IIA & IIB). Each muscle fiber type has a corresponding energy system that supplies it and determines its action and performance parameters.

·      Slow twitch (IA) utilizes oxygen (aerobic) as its primary energy source, 3 minutes or longer duration and has an intensity threshold of 25% or less of the persons strength capacity and is used during postural and endurance activities.

·      Fast twitch oxidative glycolytic IIAo utilizes glycogen (anaerobic) and oxygen (aerobic) as its energy sources and is strength endurance oriented, 2 to 3 minutes in duration and has an intensity of 25% to 60% of a person’s maximal strength capacity.

·      Fast twitch glycolytic IIA utilizes glycogen (anaerobic) as its primary energy source and is strength oriented, 13 to 30 seconds in duration and has an intensity of 60% to 85% of a person’s maximal strength capacity.

·      Fast twitch phosphogenic IIB utilizes creatine phosphate (CP) and adenosine triphosphate (ATP) (anaerobic) as its primary energy sources and is explosive-power oriented, 1 to 12 seconds in duration and has an intensity threshold of 85% to 100% of a person’s maximal strength capacity.

·      Examples: 25-50 mile race vs.800-1500 meters vs. 200-400 meters vs. 50-100 meters sprint.

9. Muscle Receptors and Sensors – within the muscles there are various receptors and sensors (proprioceptors) that perform specific tasks e.g.,

·      vestibular receptors- measure balance and equilibrium;

·      muscle spindle- measures change in muscle fiber length and change in muscle fiber speed;

·      Golgi tendon organ- measures the range of motion (rom) or stretch in muscle tendons;

·      Ruffini receptors- measures the position of the muscle and joint in relation to space;

·      Pacinian corpuscle- measures the tension and pressure within the muscle fiber and tendon.

·      All of these sensors relay information from the muscles to the spinal cord and/or to the brain or central nervous system. In turn the appropriate muscle response occurs.

Training Principles, Part Two - Principles Of Exercise Science

By James Walker CCS, STM, BioSig, Master Trainer

There are quite a few scientific principles that apply to training. I will list some of my favorites that I use daily.

1. Central Nervous System Training (CNST) – is made up of the brain, spinal cord, nerve pathways, and sensors to the muscles and organs.

·      The impulse or signal to the muscles from the spinal cord is called neural drive, involving motor or efferent neurons, nerve fibers, motor units, motoneurons, and muscle fibers.

·      Things that interrupt and obstruct neural drive are poor posture, improper form, flexibility and strength imbalances, nerve injury, and scar tissue.

·      Demonstrate-ROM with proper vs. poor flexibility, seated rotation or elbow retraction

2. Critical Drop Off (CDO) – after the first set If the rep number drops by more than 2, e.g., from 6 to 3 reps or 20-30%, the particular exercise should be discontinued.

·      This drop off indicates neuromuscular exhaustion so stopping will prevent over training, reduce the possibility of injury, and allow the super compensation process to begin. So move on or continue with the next exercise.

3. Exercise Variation (EV) – by varying the exercises for each cycle over training and muscle imbalance can be significantly reduced.

·      For example during workout cycle one a flat chest press can be performed and for workout cycle two an incline press can be done.

·      Exercise variation may include changes in exercise selection, or changes in hand, foot, limb angle, or body position, and in apparatus type.

4. Faulty Muscle Recruitment (FMR) and Loading Patterns – faulty muscle recruitment occurs as a result of performing a task incorrectly and may be caused by:

·      Scar tissue present within the muscle which impedes its ability to function normally.

·      A muscle imbalance that effects the neural drive to the muscle.

·      Using too heavy a load so that the appropriate muscles can not perform the task.

·      Continuing to train while not addressing any of the previous issues or several other factors.

·      Remember how you practice will influence how you play and perform.

5. Faulty Loading Patterns (FLP) and Muscle Type Response – stability muscles also known as postural or tonic muscles tend to shorten and tighten under faulty or improper loading.

·      Their composition seems to be mostly slow twitch or IA type fibers.

·      While the dynamic, explosive, or phasic muscles tend to lengthen and weaken under faulty loading.

·      They seem to be made up of a predominance of fast twitch IIB and IIA fibers.

·      This is the general rule but some muscles may have dual roles and have a composition of several fiber types.

6. Muscle Action Response (MAR) – most muscles will be comprised of both fast and slow twitch fibers, however the percentages or ratios will vary based on genetics, and muscle group but training will affect it’s development.

·      E.g., fast vs. slow ratio may be 40:60 or 50:50 or 60:40 or 70:30, this will determine your athletic preference and possible physical training potential.

·      Muscles that flex joint angles like the arm and leg biceps tend to be comprised of mostly fast twitch fibers.

·      While muscles that extend the joint like the leg quadriceps and lower back erectors will have a greater endurance capacity.

·      Remember this is the general rule, individuals need to be tested to determine their specific muscle response.

Does Exercise Science Matter?

By James Walker CCS, STM, BioSig, Master Trainer

Does exercise science matter when training? First of all, what is exercise science? Exercise Science is the study of human movement and the related biological responses. Movement becomes a science through precise study, analysis, and documentation of exercise and sport type activities. It involves biomechanics, kinesiology, physiology, and health and constructs usable principles from this science into training. Well what are these principles of exercise science? There are many exercise science principles. In this article I will list and briefly describe 10 scientific principles of training, in no particular order.

1. Super Compensation is the amount of time required for the body to fully recover from the previous workout or workouts.

• There should be full recovery prior to repeating the same muscle workout for the best gains.
• This will result in strength increases of 1-2% or by 1-2 repetitions each week.
• Optimal increases will not occur with out the proper rest, recovery, and regeneration.

2. Periodization – is a pre-planed training plan, which consists of short or long-term cycles (days vs. weeks vs. months), with changes in the workout at regular intervals.

• By manipulating your training variables, such as variations in exercises, reps, sets, and weight load intensities you will maximize your progress and motivation, and help to prevent plateaus, injuries, and over-training.

3. Time Under Tension (TUT)  is the time required to complete a rep or a set (group of reps). TUT is influenced by the tempo.

• Muscle fiber type recruitment and energy system type utilization depends on time under tension.
• e.g., tempo x reps = total time under tension per set, 302 tempo = 5 seconds total tempo x 6 reps = 30 seconds of time under tension per set.

4. Tempo-is the pace, rhythm, and time required for each repetition.

• Planned tempo use will ensure correct muscle fiber and energy system recruitment, and will reduce injury and faulty motor patterns.
• Tempo is usually expressed in counts e.g., 302, 301, 30X or 402, 401, 40X, or 502, 501, 50X, that are normal but may be 31X, 512, 911 counts.
• The first number represents the negative (eccentric) phase of the rep, usually expressed in a 2-9 range.
• The second number usually represents the midway point, usually expressed in a 0-2 range.
• The last number represents the positive (concentric) phase, usually expressed in a X-2 range.
• e.g., a 302 tempo for an arm curl, starting position at the bottom with the weight in front of thigh, a 2 count is performed while the weight is curled up to the shoulders, a 0 pause at the top or midway position,  a 3 count is done while lowering the weight to the start.

5.Technique and Posture – proper form and posture are necessary for correct muscle recruitment and optimal strength gains.

• If a movement cannot be performed with the correct technique, form, and posture it should be stopped.
• An assessment should be made to determine the reason, so that the necessary corrections can be made.
• Remember correct technique and posture will optimize neural drive to the correct muscles and will prevent faulty muscle recruitment patterns and injury.
• e.g., excessive forward lean vs. upright torso in the squat, places undue stress on the knees and lower back regions.

6. Reflex Inhibition –when a muscle is injured by repetitive use, trauma, faulty motor patterns, imbalances, or scar tissue, the central nervous system shuts down the neural drive to the muscle (turns off the muscle) to protect it from further injury.

7. Posture, Stability, and Synergist Muscles – are muscles that assist the primary (larger) muscles by helping to hold a position to achieve the desired action. This help is called synergist.

• e.g., when sprinting the ankle dorsi-flexor muscles and the toe extensor muscles put the foot in the correct position prior to the foot strike.
• The synergist may also assist in achieving a particular action.
• ,e.g; in elbow flexion the arm biceps muscle may get assistance from the forearm brachioradialis muscle.
• Often these muscles are the smaller muscles and/or the secondary actions of neighboring muscles.

8. Over Training-is caused by constant training that does not allow adequate time for recovery, regeneration, or super compensation to occur.

• Symptoms may include irritability, increases in injury, healing time, resting heart rate, normal blood pressure, illness, and changes in mood and appetite, decreases in immune system and performance.
• In addition there may be excessive inflammation, scar tissue formation, over compensation by other muscle groups, soft tissue strains and tears, bone fractures, and a weakened level of strength and conditioning.

9. Overload and Progressive Loading – neuromuscular adaptation occurs as a result of progressive amounts of overload or in other words your body adapts to small progressive amounts of stress (the fictitious Greek wrestler Milo carrying the calf until it’s a full grown bull).

• This adaptation is optimal when the progression of stress or overload is gradual and in small increments of 1-5% of the working intensity level (also called the Kaizen Principle of constant and never ending improvement by increasing in small increments over a long period of time).

10. Central Nervous System (CNS) – is made up of the brain, spinal cord, nerve pathways, and sensors to the muscles and organs.

• The impulse or signal to the muscles from the spinal cord is called neural drive, involving motor or efferent neurons, nerve fibers, motor units, motoneurons, and muscle fibers.
• The central nervous system response is extremely fast and gets better with repeated efforts but happens instantly, e.g., picking up a pencil vs. picking up a 50 lb dumbbell. The CNS instantly determines if the task can be completed, what muscles to recruit, and how to perform the task. It knows the difference between the weight of the pencil and the 50lb dumbbell even with your eyes closed by touch and feel.
• Things that interrupt and obstruct CNS neural drive are poor posture, improper form, inflexibility, strength imbalances, nerve injury, and scar tissue.

These are just a few of many scientific principles that can and should be incorporated into a training program. By incorporating them you will achieve results at a much faster, safer, calculated, predictable, and repeatable outcome. Look for a trainer or strength coach who understands and employs principles such as these and you will be on your way to new gains in strength and a different outlook towards training.
