TRAINING AND
CONDITIONING
TECHNIQUES
Chapter 4
Overview
• Lack of physical fitness is one of the primary
causes of sports injury.
• Coaches and athletic trainers should work
cooperatively to supervise training and
conditioning programs.
• The coach and athletic trainer must possess
sound understanding of the principles of
training and conditioning relative to flexibility,
strength, and cardiovascular endurance.
Relationship Between Coaches,
ATC’s, and CSCS’s
• All must work together for the common good.
• High schools may not have ATC’s or CSCS’s
– The coach is responsible in their absence
– It is important to implement all aspects of a
strength and conditioning program
•
•
•
•
Flexibility
Strength
Cardiovascular fitness (aerobic, anaerobic)
Nutrition etc.
Periodization
• Periodization: organizes a training and
conditioning program into cycles
• Macrocycle: usually one year-long cycle
–
–
–
–
Preseason
In-season
Post-season
Off-season
Periodization
• Mesocycle: usually lasts weeks or even months
– Transition (post-season): recreational exercise
– Preparatory (off-season): emphasis for gains
• Hypertrophy phase: low intensity and high volume
• Strength phase: moderate intensity and moderate volume
• Power phase: high intensity and low volume
– Competition (in-season): maintainance
• Includes a mix of intensities and volumes
• Microcycles: during a week may help the athlete peak at
the end of the week.
– Intense early in the week
– Light at the end of the week

•
Specificity
Individuality
Minimize stress
Safety first
Improving and Maintaining
Flexibility
• Flexibility: the ability to move a joint or series of
joints smoothly and easily throughout a full range
of motion.
• An athlete who has a restricted range of motion
will realize a decrease in performance capabilities.
• Flexibility is important in preventing injury to the
musculotendinous and skeletal anatomy.
Factors That Limit Flexibility
•
•
•
•
•
Bony structure
Excessive fat
Skin
Muscles and tendons
Connective tissues
• With the exception of bony structure, age, and gender, all
of the other factors that limit flexibility may be altered to
increase range of joint motion.
Range of Motion
• Active Range of Motion
(dynamic flexibility)
• Passive Range of Motion
(static flexibility)
• Resistive Range of
Motion (strength)
Stretching Techniques
• The goal of any effective
flexibility program
should be to improve the
range of motion at a
given articulation by
altering the extensibility
of the musculotendinous
units that produce
movement at that joint.
Stretching Techniques
• Warm-up
• Stretch to the point of tightness
• Stretching is specific only to the muscle you
stretch.
• Avoid stretching joints and ligaments
• Stretch slowly and under control
• It is recommended to stretch 5 to 6 times per
week.
Stretching Techniques
• Ballistic stretching
– Involves a bouncing movement
– May cause muscle soreness
• Static stretching
– Passive stretch (hold for 30 seconds)
– Is very safe to perform
• Proprioceptive Neuromuscular Facilitation (PNF)
– Involves a combination of stretches and contractions
– Use a 10 sec. push phase and a 10 sec. relax phase
Stretching Techniques
• Proprioceptive Neuromuscular Facilitation (PNF)
– Slow-reversal-hold-relax
– Contract relax
– Hold relax
• PNF is based on the “stretch reflex”
– Muscle spindles – reflexively contract
– Golgi tendon organs – reflexive relaxation
• Golgi tendons override the muscle spindles over time
Stretching Techniques
• Autogenic inhibition: relaxation of the muscle
during or after contraction (tension).
– Uses the contract relax method
• Reciprocal inhibition: a contraction of the
opposite muscle causes a reflex relaxation in the
muscle to be stretched.
– Uses the slow-reversal-hold technique
– Uses the hold relax method
Stretching Techniques
• Increased ROM can be determined with a goniometer at
the joint.
• Other flexibility tests (tape measure)

Sit and reach
Trunk extension test
Trunk rotation test
Shoulder lift test
Stretching Techniques
•

Strength Training
• Muscular strength
• Muscular endurance
• Muscular power
Strength Training
• Skeletal muscle is capable
of three types of
contractions.
–
–
–
–
–
Isometric
Static
Concentric
Eccentric
Isokinetic
Strength Training
• There are three basic types of muscle fibers
– Slow-twitch (type I)
– Fast-twitch (type IIa)
– Fast-twitch (type IIb)
• It now appears that there can be almost any change of
these fibers in response to training.
Strength Training
• Factors that determine muscular strength
–
–
–
–
Hypertrophy vs atrophy
Size of the muscle
Neuromuscular efficiency
Biomechanical factors
• Mechanical (leverage) advantages (genetic)
• Length-tension relationship (optimum is 90 deg.)
– Overtraining
– Reversibility
Strength Training
• Physiology of strength development
–

Fiber splitting theory
Capillary density with training
Myofilament increase (protein synthesis)
Increased bone and collagen increase
Increased enzymes
Enhanced energy use of the muscle etc.
Strength Training
• Techniques of Resistance Training
– Isometrics (abtronics do not transfer)
– Progressive Resistance Exercise (PRE’s)
•
•
•
•
Isotonics
Overload (reps? Sets? Intensity? Frequency? Recovery?)
Progression

Females vs Males
Aerobic & Anaerobic Conditioning
• Cardiorespiratory Endurance: the ability to perform
whole-body large muscle activities for extended periods
of time.
– Involves the transport and utilization of oxygen
•
•
•
•
Heart
Lungs
Blood vessels
Blood
– Measured by maximum aerobic capacity (Vo2 Max)
• Mostly genetically determined potential
• Training determines how close you can come to your potential
Aerobic & Anaerobic Conditioning
• Measured indirectly by heart rate
• Training Effect causes stroke volume to increase while
the heart rate is reduced at a given exercise load (cardiac
output = SV x HR).
• Fatigue is closely related to the percentage of Max VO2
that a particular workload demands.
Aerobic & Anaerobic Conditioning
• Energy Systems
– The Energy Systems
•
•
•
•
ATP (retreived by creatine phosphate)
Glucose / Glycogen
Free Fatty Acids
Protein
– Aerobic -vs- Anaerobic Metabolism
• They function simultaneously
• Types of activities …..
Aerobic & Anaerobic Conditioning
• Continuous Training (aerobic)
–
–
–
–
Mode: anything that raises your heart rate
Frequency: 3 – 6 times a week
Duration: at least 20 minutes
Intensity
• Maximum HR = 220 – age (.75)
• Karvonen Equation
Target HR Zone = RHR + (.75 [MHR – RHR])
Aerobic & Anaerobic Conditioning
• Interval Training: intermittent activities with periods
of work with active recovery.
– More anaerobic
– Includes a training-recovery ratio
• Fartlek Training: “speed play”
Fitness Assessment
• Tests may be used to assess flexibility, muscular
strength, muscular endurance, muscular power,
cardiorespiratory endurance, speed, balance, agility, or
quickness depending upon the stated goals of the
training and conditioning program.
• See page 107
NUTRITIONAL
CONSIDERATIONS
Chapter 5
Athletes who practice sound nutritional habits
reduce the likelihood of injury, and enhance
performance through the development of
strength, flexibility, and cardiorespiratory
endurance. 57
Nutrition Basics
• Nutrition: is the science of the substances
that are found in food that are essential to
life.
• 6 classes of nutrients
–
–
–
–
–
–
Carbohydrates
Fats
Proteins
Vitamins
Minerals
Water
Energy Sources
• Carbohydrates
– Should account for 55% - 70% of an athletes total
caloric intake.
• Sugars (simple)
– Monosacharides (single sugars)
– Disacharides (two monosacharides)
• Starches (complex carbohydrates)
• Fiber (non digestable plants)
Energy Sources
• Fats: should be less than 30% of total calories
– Saturated (are from animal products)
– Unsaturated (are from plants and are liquid at room
temperature)
• Monounsaturated
• Polyunsaturated
– Fat substitutes are a good alternative because they
contain no cholesterol and 80% less calories.
Energy Sources
• Proteins: the building blocks of the human body
– Amino Acids: obtained through food are referred to
as the essential amino acids.
– Most of the proteins from animal foods contain all
of the essential amino acids that humans require and
are called “complete proteins.”
• The increase in muscle mass that result from
conditioning and training are associated with
only a small increase in protein requirements
that can easily be met with the usual diet and
therefore supplements are not necessary.
Regulatory Nutrients
• Vitamins: regulators of body processes
– Fat-soluble vitamins dissolve in fats
• A, D, E, and K (see table 5-1)
– Water-soluble vitamins dissolve in water
• C – used to build bone, teeth, connective tissue and
strengthen the immune system
• B’s – used to regulate metabolism
Regulatory Nutrients
• Antioxidants protect cells from destructive
agents like oxygen and lactic acid.
– Vitamin C: fruits and vegetables
– Vitamin E: vegetable oils, some fruits and vegetables
– Beta-carotene: a plant pigment found in dark green,
yellow or orange fruits and vegetables.
• Deficiency disease: results from a lack of any
nutrient.
– For most people supplements are a waste of money.
– A wide variety of foods in the diet can prevent the
need for supplementation.
Regulatory Nutrients
• Minerals: more than 20 elements have an
essential role in the body and therefore need to
be supplied by the diet.
– Magnesium: needed for energy-supplying reactions
– Sodium and Potassium: are important for
transmission of nerve impulses.
– Iron: needed for energy metabolism and is assisted
with protein to form hemoglobin (to carry O2).
• Once again minerals can be obtained by eating a
variety of foods and supplementation is not
necessary.
Regulatory Nutrients
• Water: is the most essential of all of the nutrients in the
body.
–
–
–
–
–
60% of all body weight
Necessary for temperature control
Necessary for energy production
Necessary for digestion
Necessary for elimination of waste
Regulatory Nutrients
• Water
– Replacing fluid after heavy sweating is far more
important than replacing electrolytes
– Dehydration
• Fatigue
• Nausea
• Exhaustion
• Fainting
– Electrolyte requirements
• Sodium, cholride, potassium, magnesium,
and calcium
• Can be sufficiently replaced with a balanced
diet
Nutrient Requirements and
Recommendations
• A nutrient requirement is that amount of the
nutrient that is needed to prevent the nutrient’s
deficiency disease.
• A nutrient recommendation is that which will
prevent the deficiency disease for nutrients and
calories of a given food.
– Recommended RDA helps consumers compare
nutritional value of foods.
– Dietary Reference Intake (DRI) or adequate intake
(AI)
Nutrient Requirements and
Recommendations
• Food Labels: percentages of daily values based
on a standard 2,000 calorie diet.
• The Food Pyramid: specifies the minimum
number of servings that should be eaten daily
with examples of the foods to eat (pg. 122).
Nutrient Requirements and
Recommendations
• Exercise increases the need for energy, not for
proteins, vitamins, and minerals.
• A megadose of a nutrient supplement is
essentially an overdose.
• An increased need for nutrients is easily fulfilled
when the athlete eats more nutritious foods.
– Exceptions include calcium (osteoporosis)
– Exceptions include iron (anemia)
Nutrient Requirements and
Recommendations
• Protein supplementation
– RDA = .8 grams per kilogram
– Athletes = 1 – 1.5 grams per
kilogram
– Athletes diets typically easily exceed
these requirements (1.8 – 4.4 grams
per kilogram).
Nutrient Requirements and
Recommendations
• Creatine supplementation
– Free creatine
– Phophocreatine
• Stored in skeletal muscle
• Used to produce ATP during anaerobic
activity
• Side Effects
Nutrient Requirements and
Recommendations
• Sugar and Performance
– Simple sugars (anaerobic benefit)
• The insulin response is not as detrimental as
once believed.
– Complex sugars (aerobic benefit)
• Provides long lasting energy
Nutrient Requirements and
Recommendations
• Caffeine: is a stimulant
– Can cause irritability, nervousness, increased heart rate
and headaches
– Enhances the use of fat for energy during endurance
exercise
– Enhances calcium absorption in the muscles for
muscle contractions
Nutrient Requirements and
Recommendations
• Alcohol

Weight Control and Body
Competition
• Overweight: having excess body weight
• Obese: an extreme amount of excess fat
– Above 30% for females
– Above 20% for males
• Assessing Caloric Balance
– Calories in and calories out
– 1500 calories = 1 lb.
Weight Control and Body
Composition
• Methods of weight loss
– Dieting
• Fad dieting is very popular but not helpful
• Dieting is a selection of all food groups
• Dieting should not be a total restriction
– Exercise
– Combinations of dieting and exercise is the
best method of losing 1 to 2 lbs. a week.

Environmental
Conditions
Chapter 6
Heat Stress
Maintenance of normal temperature in a hot
environment depends on the ability of the body
to dissipate heat.
Body temperature can be affected by 5 factors.
Heat Stress
• 5 factors that influence body temperature
– Metabolic heat production
– Conductive heat exchange
• Direct contact with the turf
– Convective heat exchange
• Uses a circulating medium like wind or water
– Radiant heat exchange
• Radiation from the sun
– Evaporation heat exchange
• Sweat evaporates taking large amounts of heat with it.
Monitoring the Heat Index
• Wet Bulb Globe Temperature (WBGT)
– Dry bulb temperature (DBT)
• thermometer
– Wet bulb temperature (WBT)
• Sling psychrometer
• Use the WBGT Index (pg. 141)
• Use a Relative Humidity Index
Heat Illnesses
• Heat Rash (prickly heat)
– Red raised rash
– Tingling
• Heat Syncope
– Rapid physical fatigue
– Fainting, nausea caused by pooling of blood in the
extremities to try to cool the body off.
Heat Illnesses
• Heat Cramps
– Painful muscle spasms
– Usually occur in the calf, hamstrings &
abdomen
– Related to loss of water and electrolytes
– Treated with water, electrolyte drinks,
stretching the muscles, and cooling the body.
Heat Illnesses
• Heat Exhaustion

Altitude
• At high altitudes the athletes oxygen uptake is
decreased causing a decrease in performance.
• The body compensates by increasing the heart
rate (tachycardia).

to dehydration
• Causes skin cancer and skin aging
• Sun Protection Factor (SPF)
– SPF 30 sunscreen is advised when participating in
outdoor events lasting long durations.
Electrical Storms
• Flash-to-Bang: provides an
estimation of how far away the
lightning is.
