THE SIX COMPONENTS OF PERSONAL TRAINING



The Los Gatos Swim & Racquet Personal Training Program is

composed of six distinct steps that are designed to provide

clients with the most comprehensive training program

available. While any of the six components may be used

independently, the complete Personal Training

Program uses an effective and proven process to get maximum

results and help clients attain their goals

Through the Six Components of Personal Training you will

enjoy several important benefits:

o Increase the burn of fat and calories

o Improve cardiovascular fitness and athletic performance

o Exercise without over-training or developing muscle soreness

o A Strength Training Plan to increase lean muscle mass and boost metabolic rate.

o Increase muscle mass

o Enhance flexibility

o Improve core strength

o Enhance balance

o Boost power

o Improve quickness

o Increase agility

o Boost strength

o Speed injury recovery

COMPONENT ONE - ASSESSMENT

RESTING METABOLIC RATE (RMR)

Step One begins with a determination of your daily caloric requirements using a Resting Metabolic Rate (RMR) assessment. This information is essential in creating the most appropriate dietary and nutritional plan for you. The client learns:

· What caloric deficit is required to lose weight
· How many calories are burned from fat compared to carbohydrates
· How many calories they can consume without gaining weight

EXERCISE ASSESSMENT

Everyone’s response to exercise is unique. To get the best results, it is very important to
know the correct exercise intensity that will provide the optimum, sustainable burn of
fat and calories, improve your fitness and athletic performance.
The New Leaf Exercise Assessment provides a metabolic profile that eliminates the
estimations and guesswork that defeat most diet, exercise and training programs. The New Leaf Exercise Assessment helps you the client:

· Understand your unique response to exercise
· Learn your individual fitness level and how you compare to others of your age
· Know the correct heart rate exercise intensity to increase your burn of fat and calories
· Lose weight and inches
· Improve cardiovascular fitness and athletic performance
· Avoid muscle soreness and over-training
· Determine your “true caloric burn” during each training session

KINETIC CHAIN ASSESSMENT

All strength training programs are designed based on a comprehensive and individualized kinetic chain assessment. This head-to-toe fitness and performance evaluation assesses an individual’s strengths and weaknesses in the areas of:

· posture
· movement
· strength
· flexibility
· and athletic performance.

Movement observations are often the quickest way to gain
an overall impression of a client’s functional status. As posture
is a dynamic quality, these observations show postural distortion
in a dynamic setting. The observation process serves as a search
for imbalances in anatomy, physiology or biomechanics that may
decrease client’s results and possibly lead to injury both in and out of
the fitness environment. The Overhead Squat and Single Leg Squat are movement assessment tools that helps detect muscle imbalances by objectively assessing total kinetic-chain neuromuscular efficiency, integrated functional strength and dynamic flexibility. This is a simple assessment procedure that provides your Fitness Professional with a wealth of information.

BODY COMPOSITION ASSESSMENT

Bioimpedance testing provides health care practitioners with a non-invasive tool for objectively monitoring body composition – a key indicator of health and vitality. These measurements increase the certainty of an accurate assessment and allow the practitioner to develop and prioritize nutrition and strength programs.

Bioimpedance Measurements: Readout of the client’s resistance, reactance, and phase angle. This information is obtained through a direct measurement of the complex impedance of the human body.

Mass Distribution: Mass consists of lean body mass (or fat-free mass) and fat mass. Lean body mass is further broken down into its two key components – body cell mass and extracellular mass. Body cell mass is the total cellular mass of living cells. It is the metabolically active tissue of the body. Extracellular mass is the fluid and tissue of the body found outside the cell.

Water Compartments: Total body water, and its two components – intracellular water and extracellular water. Intracellular water is the fluid contained within the cell. Healthy cells maintain their integrity and hold their fluids inside. Extracellular water is the fluid outside the cell. An increase in extracellular water may indicate disturbance in the cellular membrane.

COMPONENT TWO - FLEXIBILITY TRAINING

Flexibility training is a key component for all training programs. The purpose of flexibility training is to:

· Correct Muscle Imbalances
· Increase Joint Range of Motion
· Decrease Muscle Soreness
· Decrease Muscle Hypertonicity
· Relive Joint Stress
· Improve the Extensibility if the Musclulotendinous Junction
· Maintain the Normal Functional Length of All Muscles
· Improve Optimal Neuromuscular Efficiency
· Improve Overall Functional Ability

Today, more than ever, individuals are plagued by the following conditions:


· Muscle imbalances
· Joint dysfunctions
· Postural imbalances

To be truly effective in helping our clients achieve optimal levels of function, we must first develop a plan or strategy to guide us in our programming. This Plan is lies within the Integrated Flexibility Continuum. Within the Integrated Flexibility Continuum there are three divisions of flexibility – Corrective, Active, and Functional – each designed with specific objectives.

CORRECTIVE FLEXIBILITY

This type of flexibility applies appropriate stretching techniques to improve muscle imbalances, postural distortions and altered neural tissue dynamics. Corrective Flexibility utilizes static stretching as well as self-myofacial-release techniques in addition to neuromuscular and neurodynamic stretching.




ACTIVE FLEXIBILITY

This type of flexibility applies three stretching techniques designed to improve soft-tissue extensibility and neuromuscular control by utilizing the principles of reciprocal inhibition and autogenic inhibition. Active flexibility utilizes active isolated techniques, neuromuscular stretching with antagonistic contraction and self-myofacial release with antagonist contraction.

FUNCTIONAL FLEXIBILITY

Functional flexibility applies dynamic stretching techniques to improve soft-tissue extensibility by using the body’s muscles to control the speed, direction and intensity of the stretch

COMPONENT THREE - STRENGTH TRAINING


Strength Training is an important aspect of any weight loss, fitness, or
performance program and is used to increase your lean muscle mass and boost
your metabolic rate. The appropriate Strength Training program for each client
is designed specifically with the goals, needs, wants and abilities of the particular client in mind.

Until now, most training programs have been based almost entirely on the

experiences and goals of bodybuilders, coaches, and athletes. Scientifically

unsupported training programs are not designed to meet the needs of our

increasingly de-conditioned and injury-prone society.


The National Academy of Sports Medicine’s exclusive Optimum Performance

Training (OPT) method represents the industry’s first and only comprehensive

training program based on current scientific research that provides undisputed

results specific to individual needs and goals.


Creating a new industry standard for success, OPT virtually eliminates

programming and program-design guesswork for anyone at any fitness

level. By following the systematic OPT method; our certified

professionals develop training, conditioning, or rehabilitation programs

scientifically proven to produce remarkable results.



By incorporating multiple types of training—
flexibility, cardio respiratory, core,
balance, reactive, speed, agility, quickness, and
strength—into every program,
the revolutionary and easy-to-follow OPT
method improves all biomotor abilities
and builds high levels of functional strength, neuromuscular efficiency, and
dynamic flexibility.

COMPONENT FOUR - ENERGY SYSTEM TRAINING USING A HEART RATE MONITOR


The Surgeon General and the American College of Sports Medicine
suggest that adults should engage in a minimum of 30 minutes of
“moderately intense” physical activity every day. But what constitutes
as moderately intense activity? Many exercise programs specifically
spell out the strength training portion, and yet they leave you in the
dark with your cardio. There is no specific planning so most people just go for a leisurely jog.
Others just hop on a stationary bike for 20-30 minutes while reading a magazine or watching
ESPN. Most individuals don’t work nearly as hard as they should and thus waste time and fail to
tap into their potential. They do the same thing every day, their bodies stop adapting, and they
end up looking pretty much the same at the beginning and end of whatever program they’re on.
I dislike the term “cardio” for that very

reason. Over the years it’s come to mean

“light exercise”. At the Los Gatos Swim &

Racquet Club, we refer to cardio as Energy

System Training, or EST, because were not

just burning calories for the sake of burning

them, were also improving the function of

the heart and lungs and building endurance.

In short, were teaching the body to tap into
new energy levels.





For maximum effectiveness, it is important to keep your Energy

System Training exercise in the correct zone based on your metabolic

profile. The heart rate training plan and heart rate monitor will help

guide you the client to exercise at the optimum frequency, intensity

and duration to achieve your goals.

COMPONENT FIVE - NUTRITION TRAINING PLAN




Just like your Flexibility Plan, Strength Training Plan, and Energy System

Training Plan, you need to be proactive about your about your “calories in,”

and create a Meal Plan. Having the proper Meal Plan in place will ensure that

you maximize energy, lose fat, gain lean mass, and save time and money.

The Nutrition Training Plan is an individualized program that teaches

the principles of good nutrition and long-term, dietary changes. The program

is individualized based on the client’s weight loss objectives, RMR, and other

health factors.





It is easy to use and is available on the web or from

printed copies so clients can use it anywhere,

anytime. The standards and recommendations used

in the Nutrition Program are those of the American

Dietetic Association, American Heart Association and

the American College of Sports Medicine.













Using the Nutrition Training Program, clients learn how to:

· Choose what to eat

· Read a food label

· Know how much to eat

· Count fat grams

· Plan healthy meals – breakfast, lunch, dinner and snacks

· Shop wisely

· Cook healthy

· Dine at restaurants

· Deal with slips and set-backs

COMPONENT SIX - REASSESSMENT, PROGRESS EVALUATION & ADJUSTMENT

At some point during your program, you will need a follow-up

RMR, Exercise Assessment and measurement of other body

metrics to evaluate your progress and adjust your training

program. As you become more fit, your Personal Trainer may

increase the intensity, duration or frequency of your Energy

System Training and Strength Training Plan. Pounds, inches and

body fat loss, increased RMR, improvements in cardiovascular

fitness; flexibility and strength are other important values to

reassess. Reassessments and evaluations are typically

performed between six and twelve weeks following the start of

the program based on your rate of improvement. Progress evaluations provide several benefits

to you and your Personal Trainer that include:

· Knowing precisely how you are responding to the training program
· Offering incentive and motivation for you to stay with the program
· Having the opportunity to adjust the training program and compensate for the changes in your body’s metabolic profile


The complete Six Step Program offered by The Los Gatos Swim & Racquet Club provides you



with a unique set of tools to be assessed, evaluated

and have a unique, individualized plan



developed that gets the results you want. The Six

Step Program will help you improve the



effectiveness of your training.

Understanding the Deep Muscle Stimulator


The DMS is a new therapeutic machine developed for those suffering from muscle pain. The Deep Muscle Stimulator provides relief for people suffering from chronic pain and restricted movement.

This is the only unit in the arena of modalities that can increase ROM immediately for individuals. The DMS provides soft tissue treatment with excellent results.

WHAT DOES THE DMS DO?

Much of muscle pain stems from various conditions; strain, lactic acid build up, scar tissue, etc... The DMS uses percussion, mechanical vibrations that reach deep into the muscle tissue to stimulate proprioceptive functions. No other device on the market matches the effectiveness of the DMS.

The DMS provides deep muscle tissue with kinetic forms of percussion and concussion vibration, which in turn facilitates the patient or athlete with the benefits of:

Increased circulation
Reduced pain
Faster rehabilitation from injury
Increased lymphatic flow
Break up of muscular scar tissue
Reduced lactic acid build up
Tissue Regeneration
Soft & Active tissue release

The DMS also concentrates on general or local muscle spasms. It increases muscle metabolism and increases the lactic acid cycle to relieve pain. Deep, rapid, short-duration percussion is the key to the elimination of pain. The DMS can be used in effective management of acute and chronic pain, not exclusive to, but including: migraine headaches, sciatica, TMJ, carpal tunnel syndrome, tendonitis, bursitis, edema, myofacial pain and frozen joints.

The Deep Muscle Stimulator is known to increase the circulation of blood and flow of lymph. The direct mechanical effect of rhythmical pressure and movement used in DMS can dramatically increase the rate of blood flow. The stimulation of nerve receptors causes the blood vessels to dilate, which also facilitates blood flow.

DMS can help loosen contracted, shortened muscles and can stimulate weak, flaccid muscles. This muscle "balancing" can help posture and promote more efficient movement. DMS is also being used for Integrated Manual Therapy and Musculoskeletal Dysfunction.

It is possible to do more exercise and training, which in the long run strengthens muscle and improves conditioning. DMS also provides a gentle stretching action to both the muscles and connective tissues that surround and support the muscles and many other parts of the body, which helps keep these tissues elastic.

DMS also aids recovery from soft tissue injuries such as sprains and strains. This is possible because the growth and repair of tissue are accelerated by efficient circulation in the injured areas and appropriate stimulation of the healing tissues.

iTonic Whole Body Vibration Training


What is Vibration Training?

Vibration Training is a neuromuscular training method which uses vibration stimulus to incite an involuntary response in muscles. Mechanoreceptors are the sensory organs of the muscles which are sensitive to mechanical stimulation. When stimulated by vibration, the mechanoreceptors send impulses to the spine and cause the muscle to contract and relax at the rate of the vibration, a phenomenon called Tonic Vibration Reflex (TVR). This response recruits nearly 100% of the muscle fibers in contraction and enhances neuromuscular efficiency. Skeletal muscles contract and release at the same frequency of the vibration, for example if standing in a squat position on the vibration platform set at 30Hz, muscles will contract and release 900 times in a 30 – second session.

The mechanical rationale behind using the iTonic Vibration Platform is a simple yet powerful formula:
Force = Mass X Acceleration. In traditional strength training, force production is primarily affected by Mass or increasing load by adding weight to an exercise. In Vibration Training, we look at the acceleration variable. The acceleration variable is increased as the result of the platform rapidly moving up and down at a specific frequency. Parameters in Vibration Training are: Hertz (Hz) – the frequency at which the platform travels up and down in one second, Amplitude (L/H) – the vertical distance the platform moves in one second (2mm – 4mm). In the instance of vibration, velocity is the speed at which the platform moves the distance in amplitude. Time is defined as how long it takes to make one vibration. Mass is body weight. Force is the amount of resistance the body is experiencing.


Benefits of Vibration Training
· Time – efficient workout
· High muscle activation with less fatigue
· Boost metabolism and burn calories
· Build core strength, stability and balance
· Improve muscle mass and tone
· Decrease Cortisol (stress hormone)
· Increase testosterone and growth hormone levels
· Easy on the joints
· Increase joint mobility
· Facilitates blood circulation
· Helps to increase bone density to combat osteoporosis



Flexibility and Mobility
Research shows that Vibration Training improves muscle flexibility and range of motion in joints. The significant factors involved are the stretch reflex, reciprocal inhibition, increased heat and pliability, decreased discomfort or pain and the ability of muscles to adopt a new, greater length instantly. The linked responses are positively influenced by vibration and result in warm, elongated, fluid, adaptable muscles and connective tissues, and, ultimately, in an improved range of motion.
When tight muscles are stretched on the iTonic, the vibration reflex and reciprocal inhibition gently and safely allow new range of motion for the muscles being stretched. Traditional contract/relax stretches take minutes to accomplish, and often require a partner, but the iTonic allows a lone individual to achieve greater flexibility in 30 seconds or less.

Regeneration & Recovery
Vibration Training on the iTonic encourages regeneration and recovery, thereby providing immune-boosting benefits, stress reduction, and a sense of well being and ease. The relaxation response results from the activation of the body’s natural reflexes: the alternating contract/relax phenomenon, which activates autogenic inhibition, improved circulation, flexibility, delivery of nutrients and oxygen, and a hormonal response inducing relaxation.
In this respect, the iTonic can act in the same way that bodywork, therapeutic massage and other relaxation techniques do. It benefits the ease and balance of the autonomic nervous system by interrupting negative feedback loops, switching off the pain/spasm cycle and easing tight muscles.

Strength and Power
Vibration Training on the iTonic encourages smarter, stronger, faster neuromuscular systems and offers immediate benefits of improved strength and power, greater hormonal balance, and structural enhancements to muscles and movement patterns that occur over time.
The enhanced neuromuscular development and reinforcement of strength results from high force production and low stress, low impact training.


The iTonic allows clients to perform more work and force production in less time, and to create movement efficiency and skill. Vibration Training positively impacts on every system required for all of the applications of force: neural systems as well as, physiological, mechanical, metabolic and hormonal systems.

Nutrition Basics

The average adult eats close to one million calories a year. Despite this huge number, most healthy people are able to maintain a relatively constant body weight over years and decades without much conscious effort. When “calories in” equals “calories out,” a state of energy balance is achieved and body weight remains constant.

Energy balance is driven by a common law of physics: Energy cannot be created or destroyed. Energy must be either used or stored. When “calories in” is less than “calories out,” a state of negative energy balance occurs and body weight decreases. In contrast, when “calories in” is greater than “calories out,” a state of positive energy balance occurs and body weight increases. Overweight is the end result of a mismatch between “calories in” and “calories out,” that is produced by multiple, interrelated causes including genetic, cultural, and hormonal factors.

Just like your Strength Training Plan, Flexibility Plan, and Energy System Training Plan, you need to be proactive about your about your “calories in,” and create a Meal Plan. Having the proper Meal Plan in place will ensure that you maximize energy, lose fat, gain lean mass, and save time and money.

Starting a Meal Plan begins with the basics, the number of meals per day. Having five to six meals per day means that you will have something to eat every 2 ½ to 3 hours. When you eat regularly and often your body adapts to such a schedule and then becomes a more efficient calorie burning machine. In addition, eating frequently keeps you from overeating. If you know that you are going to have something in a couple of hours, you’ll be less likely to overeat and be less likely to be extremely hungry.

One of the many reasons why people don’t eat well is because they don’t plan ahead. They allow their body to get to a certain stage of hunger where poor decisions are made on the quality and quantity of food, so they end up devouring whatever they can grab. Stressing out over where and when to eat is unhealthy, a problem made worse by the junk that is inevitably consumed in such a state. As a result you end up increasing body fat and decreasing lean mass.

Eating well, like working out properly, is a matter of understanding a few concepts and then implementing them. If you have a proper Meal Plan in place, you’ll find that eating healthy is less stressful, less expensive, and more enjoyable.

The Energy Balance Equation

“Calories In”

Food provides calories (energy) for the body in the form of carbohydrate, protein,
alcohol and fat. Any calories from food that are not used immediately for energy
production are stored. Each source of calories is unique in the way it is used and
stored by the body.

Carbohydrate is usually the main source of energy for the body. Carbohydrate contains four calories per gram. Carbohydrate is stored in the body as glycogen. The body can only store limited amounts of carbohydrate as glycogen.

Protein is used by the body to build and maintain body tissue and to regulate body processes. Protein also contains approximately four calories per gram, but protein is rarely used by the body for energy. Like carbohydrate, the body can only store limited amounts of protein.

Alcohol, although not a major source of energy for the body, contains seven calories per gram. When alcohol in consumed, it is immediately used as fuel and is not stored in the body. Alcohol may contribute to the storage of fat by causing fat that is eaten to be stored rather than used as fuel.
Fat is the most calorie-dense of the nutrients. It contains nine calories per gram. Body fat is the preferred way to store energy. Unlike carbohydrate and protein, the body is very efficient at storing the fat you eat as body fat. The body has an almost unlimited capacity to store fat.

“Calories Out”

Counting the calories provided by the food you eat tells you your “calories in,”
But to balance your energy you also need to know your “calories out.” The body
Uses (or burns) calories in three ways:

Thermo Effect of Food

The body uses calories to digest, absorb, transport, and store food. This process
is called the thermic effect of food. Typically, the thermic effect of food represents
only about 10 percent of the “calories out.” However, the precise number of
calories used to process the food you eat is primarily influenced by the type of
food you eat. The thermic effect is higher for protein and carbohydrates than for
fat. That is one reason why it is much easier to gain weight from excess calories form fat than from excess calories from carbohydrates. Eating a low fat diet is important for weight loss and weight management.

Physical Activity

The body uses calories for physical activity. Physical activity includes exercise as well as all other activity that uses muscles for movement, including fidgeting. Because most physical activity is voluntary (you choose to be active or sedentary), it is the most variable part of “calories out” in the energy equation. The number of calories burned during physical activity and exercise varies from individual to individual and form day to day. Calories for physical activity may represent less that 20 percent of “calories out” for a sedentary person or more that 30 percent of “calories out” for someone who is very physically active. Calories for physical activity depend upon the type of activity, intensity (how hard you exert yourself), and duration (minutes) of the exercise.

Resting Metabolism

The body uses calories to sustain life. Resting metabolism provides the energy the body needs for pumping blood through the body, inhaling and exhaling air, maintaining body temperature, sending and receiving nerve impulses, thinking, and making important chemicals in the cells. Resting metabolism occurs in a continual process throughout 24 hours a day and remains relatively constant over time. Resting metabolism is the largest component (typically 60 to 70 percent) of “calories out” in the energy equation.
