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, Four - Principles Of Exercise Science Con’t

By James Walker CCS, STM, BioSig, Master Trainer

10. Overload and Progressive Loading – neuromuscular adaptation occurs as a result of progressive amounts of overload or in other words your body adapts to progressive small amounts of stress (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).

11. 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, increase in injury, healing time, resting heart rate, normal blood pressure, illness, change in mood and appetite, decrease in immune system and performance.

·      In addition to excessive inflammation, scar tissue formation, over compensation of other body parts, soft tissue strain and tear, bone fractures, and a weakened level of strength and conditioning.

·      Example-scar tissue, traps or hamstring or calve, get volunteer

12. Periodization or Periodized Training - 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.

13. 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 may get assistance from the forearm brachioradialis muscle.

·      Often these muscles are the smaller muscles and/or the secondary actions of neighboring muscles.

14. 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.

15. Rep and Set variation – rep and set ranges should be varied for each training cycle (2-4 weeks for advance trainees, 5-8 weeks for experienced trainees, 9-12 weeks for intermediate trainees, and 13-16 weeks for beginners).

·      This will allow total muscle and strength development and will reduce overuse syndromes.

·      For example a muscle hypertrophy workout cycle: cycle One - 6 reps x 6 sets; cycle Two - 12 reps x 3 sets; cycle Three - 8 reps x 5 sets; and cycle Four - 10 reps x 4 sets.

·      For example relative strength or power workout cycle: cycle One - 5 reps x 5 sets; cycle Two - 2 reps x 8 sets; cycle Three - 4 reps x 6 sets; and cycle Four - 1 reps x 10 sets.

·      The rep ranges should be based on your objectives, whether for relative strength and power or for hypertrophy strength or for muscle endurance, whichever need is the priority.

·      The set ranges will help determine and influence the conditioning of the muscle fibers trained.

Marvin Lewis vs. AE-Combine Preparation!

By James Walker CCS, STM, BioSig, Master Trainer

Theredzone.org, Joe Reedy of the Cincinnati Enquirer reports when it comes to evaluating talent in the draft, Bengals coach Marvin Lewis is always quick to point out “the film doesn’t lie”.

On Friday on Dan Dakich’s show in Indianapolis, Lewis did chide those who go through unusual steps of preparing for the combine, saying that the way most go about it is “asinine”.
 The Bengals did show last year, with the selection of Andre Smith, that a disastrous combine won’t wreck their chances of being selected. And for that case, neither does the pro day.
 Among other things from the interview, courtesy of our friends at Sports Radio Interviews:

On players who leave school to workout and prepare for the Combine: “The other one that just kills me is that they spend three or four years with a strength coach on a college campus and as soon as the season’s over they go somewhere else to some guy who doesn’t know them from a hole in the wall and pay this guy a bunch of money. It doesn’t make any sense at all. It used to be that they had to pay for it and now it’s part of the agent deal. They’ve cultivated a whole industry out of it. It doesn’t make sense. It’s actually asinine that if I go to school in Florida, now I have to go to Arizona to train. If I go to school in Arizona, I have to go to Georgia to train. These guys have the best facilities and the best people working with them year round and now all the sudden they got to go somewhere else. You don’t need to go away. A football player is a football player.”

On how much stock he puts in workouts at the Combine: “The workout becomes a confirmation for a lot of players. It’s got to be judged individually with the player. The number one thing is what that guy has done on his college campus. So as these college players who are going to be underclassmen who may be listening to your show should know to take stock in what they do on the football field their – junior and senior – their last two seasons and not get all caught up in what this is.”

On what the NFL Scouting Combine is: “This is just a confirmation; that I can run. I weigh this much. I’m smart enough. I can carry on a conversation. I can learn. I can understand. And I’m a good person.”

AE Response By James Walker

I respect Marvin Lewis and agree with his opinion about the best current evaluation of a prospective football payer is their game film. Although you can always find exceptions to this with those players with little or no game film such as Willy Parker, Mike Lewis, and Ray Crittenden to name a few.

I also agree that many college strength programs are top notch and do a wonderful job at preparing athletes. Though I disagree with Marvin’s premise that athletes shouldn’t seek out additional help to increase their stock especially since with the current system there is so much money and opportunity involved.

First, most college football programs involve over a 100 athletes it’s difficult to address the specific needs of individual players or a select group each week while neglecting everyone else.

Second, those athletes may have specific needs involving strength, speed, power, mobility, flexibility, agility, nutrition, technique, structural integrity, soft tissue health, etc. From a logistical perspective most of these issues cannot get addressed per individual. Therefore a critical evaluation or assessment is vital.

Third, If any of these specific needs is not addressed the athlete will be at a disadvantage and unable to display their best performance on possibly their biggest stage. Unfortunately some of them go into the combine, pro-day, or camp ill prepared by innocently overlooking their specific needs and is released. Many do not receive a second chance.

Again most college strength coaches or programs by themselves do not have the resources or time to address this individually. So under the current system the athlete needs to do whatever is legally or ethically necessary to increase their opportunity.

In-Season Strength Training: Part Two

By James Walker CCS, STM, BioSig, Master Trainer

In Part One we defined in-season training and listed the first two objectives when designing a program including exercise selection and energy system needs of the athlete. In Part Two we are discussing the remaining components that determine an athletes program, including rep range, weight load-intensity, muscle fiber type, and  work volume consideration.

An intertwined objective to consider when determining the athlete’s program is choosing the correct rep range, weight load-intensity, and muscle fiber type that’s needed to improve their performance. A blocker or outside hitter in volleyball will need to develop and recruit their fast twitch fibers, so doing between 1-6 reps, with 95-80% of their one rep max (1RM), for their phasic muscles will accomplish this. Similarly, a running back in football will benefit from the same intensity and rep ranges. Now these values can vary depending on the age, maturity, health, and genetic make up of the athlete but explosive power is the important component.

On the other hand the cross-country runner may require 15-20 reps or more, at 60-70% of their 1RM to improve their muscle endurance but may benefit from the 1-10 rep range at 75-95% 1RM to help with 100-400 meter surges or sprint finishes. Several of the top Olympic middle distance runners employ this method in their training.

Either of these athletes may require a different rep range and intensity level to address their individual structural needs. In general if their tonic or postural muscles need work a rep range of 8-15, at an intensity of 80-70% of 1RM, may be required. The specific needs of the individual will always be the most beneficial to them.

The last proponent to consider is the appropriate volume of work needed to maintain and/or improve ability without over-training. The primary focus during the season should be the development of the necessary skills, ability, and strategy needed to perform the sport or position at the highest level. The secondary focus should be on maintaining and/or improving power, strength, and conditioning that was developed during the off-season. Usually most in-season practice is devoted to game preparation, sports skills, drills, strategy, tactics, plays, and related task. Therefore most of the repetition and conditioning will come from those activities, so strength related training only needs to occupy about 10-15% of the athletes total weekly time. That can be accomplished in one or two sessions, with consideration given to adequate recovery time before the day of the competition. Ideally the strength training should enhance practices, skills, abilities, and performance, while reducing the injury potential.

Likewise, practices shouldn’t injure the athlete or hinder their strength training but allow for mutual improvement, or a complete synergistic relationship. A big mistake often made is to abandon strength training during the season. This will usually start to gradually impact performance or increase injury potential after about 14 days. The athlete may start the season strong, fast, powerful, explosive, and energetic but within a few weeks will start to exhibit weakness, slowness, sluggishness, or tiredness.

Coincidently, the residual effects from strength training may last up to 10 days; so training a muscle group at least once a week or every 7 days will allow maximal recovery and strength gains. Often world-class sprinters require up to 7-10 days to fully recover, after running a personal record.

So a cheerleader who practices about 10 hours a week, excluding a 3-hour Friday evening game, at 10% of her weekly practice time the strength training would require about 1 hour to complete. Depending on equipment, facility, scheduling, etc, the 1-hour time could be divided into two 30-minute segments as to minimize time away from skills practice. This could be accomplished with a 30-minute strength training session on Saturday (the day after the game), followed by another 30-minute session on Monday or Tuesday, which would also give plenty of recovery time prior to the game. Each session would be comprised of 4 strength-power exercises for 4-8 reps, times 2 sets; and 2-4 structural exercises for 8-15+ reps, for 1-2 sets. The exercise selection could be different for each session to target various or specific muscle groups as well.

As you can see the exercise selection, energy system, rep range, weight load-intensity, muscle fiber type, and volume all comply with her in-season strength training needs. The exercise selection should depend on her individual needs and ability level. Likewise, considering the amount of impact and repetitive stress related injuries that cheerleaders accrue i.e., sprains, strains, twists, pulls, fractures, and soft-tissue adhesions, this would help to address those concerns. Not to mention the additional strength to help with the skills execution.

In conclusion, the benefits of the in-season strength training far out-way the time, cost, injury potential, and other factors involved.  The correct, safe, and scientific approach should consider exercise selection, energy system, rep range, weight load-intensity, muscle fiber type, and volume to best address the athletes in-season needs.

How To Reduce Hamstring Pulls

By James Walker CCS, STM, BioSig, Master Trainer

Over the past few years I’ve seen a multitude of hamstring pulls and strains from elite professional athletes to very good scholastic athletes. In most instances there seems to be a common theme, structural imbalance, existing scar tissue, and a lack of strength in the hamstrings.

From an anatomical perspective the hamstrings are located on the back of the thigh and attach over the hips and over the knee joints. From a performance perspective, the hamstrings extend the hips and flex the knees.

First from a structural perspective the hamstrings have a synergistic relationship with the other muscle groups that are located near or adjacent or on the opposite side of the joint. So the muscles that attach over the front of the hip (hip flexors) have a relationship with those that attach over the back (hip extensors), the outside (hip abductors), and the inside (hip adductors).

This is important because those neighboring muscles act together to produce desired movement like sprinting, running, or jumping etc. When the hip flexors become tighter or stronger than it’s antagonistic neighbors the hip extensors, it will pull the hips forward and result in an alignment or imbalance issue. Likewise if the muscles that act to counter the excess forward tilt i.e., lower abdominals are unusually weak or dysfunctional, this further contributes to misalignment and structural imbalance. These imbalances may then cause excess strain on several muscle groups including the hamstrings. The tight muscles like the hip flexors will need to be stretched and loosened to help realign the hips.

Second there is usually scar tissue or adhesions in the hamstrings and it’s neighbors like the hip abductors and/or hip flexors. In part due to those muscles having to over compensate by assisting the hamstrings from the repetitive use and stress over time. This excess scar tissue will interfere with the proper function and recruitment of these muscles, which in turn produces more scar tissue. This may also shorten and make the muscle tight as well.

Third the hamstrings are usually weak in comparison to it’s neighbors. Since the hamstrings are part of the motor or engine, along with the hips, for those athlete’s who run, jump, throw, and sprint, they need to be strong. If you want to sprint you need a high performance engine aka, Corvette or Lamborghini or Top Fuel Dragster not a Civic or Smart car. In addition the hamstrings will help support the knee joint during planting, stopping, and changing direction, so they need to be dimensionally strong.

So if you want to reduce or minimize hamstring strains address the structural imbalance, scar tissue, and strength needs early on with a good pre-training assessment or evaluation to identify and optimize performance.
