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.

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 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.

Training Principles, Part One - Types Of Strength

By James Walker CCS, STM, Biosig, Master Trainer

There is more than one type of strength, therefore there is more than one way to strength train. Below I’ve listed some of the basic types. If you’re not familiar review and think about how each one can be applied. Of course some seems similar and could potentially overlap in application. This article is also the part of my 'Training Principles' article series, part one of nine.

1. Absolute Strength-is the maximal amount of force an individual can produce, regardless of their bodyweight and time involved, as in the shot put and contact between football linemen.
2. Endurance Strength or Muscular Endurance-is the amount of force an individual can produce over a longer period of time while resisting fatigue as in rowing, swimming, distance running, and cross-country skiing.
3. Maximal Strength-is the maximal amount of force an individual can produce in a single maximal contraction or effort, regardless of the time involved as in weightlifting, shot putting, hammer throwing, caber tossing, etc.
4. Optimal Strength-is the maximal amount of strength that an individual needs to perform their sport optimally and will vary from sport to sport, as in power lifting or weightlifting vs. table tennis or squash.
5. Relative Strength-is the maximum amount of force an individual can produce at a given bodyweight or weight class (per lb or kg), regardless of the time involved as in skiing, gymnastics, bobsledding, figure sating, cycling and wrestling, boxing, weight lifting or weight class sports. Thus it is the relationship between maximal strength and body mass and is beneficial when increasing an athlete’s strength while maintaining their bodyweight.
6. Speed Strength or Power-is the ability to produce the most force in the shortest amount of time or to overcome the resistance in the shortest amount of time as in sprinting, kicking, sprint cycling, sprint rowing, ice-skating, kayaking, etc There are three components of speed strength-explosive, reactive, and starting strength.

• Explosive Strength-is the ability to increase force after a movement has been initiated or the rate at which an individual can achieve maximal force as in the shot put, hammer throw, judo throw, or wrestle take down.
• Reactive Strength-is the ability to quickly change from an eccentric contraction to a concentric contraction as in the high jump, long jump, triple jump, volleyball, and basketball.
• Starting Strength-is the ability to produce maximal force at the start of a muscular contraction or to overcome resistance when initiating movement as in sprint start, bat swing, paddle swing. It is especially a key determinant of performance in sports where the resistance to overcome is relatively light as in table tennis.
