General Adaptation Syndrome (H. Selye)
process which occurs when body reacts to stressors; stages are alarm, resistance and exhaustion
Alarm (fight or flight response)
physiological response when we confront threat, try to escape from or try to recover from it; sympathetic nervous system releases stress hormones from adrenal glands
Catecholamines
adrenaline-like chemicals released during alarm; sometimes kill heart cells
Resistance
follows alarm; if stressor persists for more than a brief time
Higher Metabolic Rate

Lower metabolic rate
easily tired, cold, overweight
Ways body reacts in fight or flight
heart pumps faster; breathing quickens; stored sugars/fats released to bloodstream; muscles tense; digestion slows; perspiration increases; pupils dilate; sense of smell and hearing intensify; blood vessels constrict; blood pressure increases; adrenaline released
Test anxiety (ways to reduce)
study ahead of time; rest; arrive early; eat something nutritious; think positively
Three main techniques to manage stress
Avoid; Alter; Adapt
Avoid
limit exposure to environmental stressors by planning or re-arranging environment
Alter

Primary stressors
original stressor that triggers the stress response
Secondary stressors

FIT Formula
Frequency, Intensity, Time
Muscle Types (3)
smooth; cardiac; skeletal
2 Types small muscle fibers in skeletal muscles
slow twitch; fast twitch
Slow Twitch
many capillaries; slow to fatigue, more blood supply; endurance activities
Fast twitch
fewer capillaries; larger, fatigue more easily; for short intense efforts
Muscle Strength
amount of force or weight a muscle can exert or resist for a brief period; generally measured by a single maximal contraction of a muscle (1RM)
Muscle Endurance
ability of muscles to sustain repeated contractions (reps) or keep muscles under tension for an extended period of time
Strength Training Principles
Progression, Overload, Progressive Resistance, Specificity
Progression
slow, gradual process; adapt to the load
Overload
adding more resistance than body normally receives
Progressive Resistance
adapting workout to breakup boredom and achieve goals
Specificity
body will adapt to stress imposed on it in very specific manner
Non weight-bearing effects on the body
loss of muscle mass; loss of muscle strength (get weaker); increased body fat; decrease in bone density/development
3 types of contractions
Isotonic, Isometric, Isokinetic
Isotonic
muscle contraction against a constant resistance (creating movement); e.g. lifting a weight
Isokinetic
muscle contraction against a resistance that moves a constant velocity through the entire range of motion (like a rowing machine)
Isometric
muscle action in which muscle attempts to contract against a fixed limit (no muscle movement, like a wall squat)
Isotonic Contraction has 2 phases
Concentric; Eccentric
Concentric (pulling or pushing)
occurs when muscle length is shortened by the resistance (upward curl on bicep curl)
Eccentric (resisting or opposing)
occurs when muscle is lengthened under tension (downward movement of bicep curl)
Antagonistic (opposing) muscle groups
Biceps/Triceps; Chest/Upper Back; Stomach/Lower Back
Agonist
muscle group which directly engages in action around a joint which has an antagonist,or muscle that provides an opposing action
Antagonist
muscle that can provide an opposing actin to the action of another around a joint
Adduction
any movement toward the midline of the body
Abduction
movement away from the center of the body
Weakest Point Principle
gaining maximum strength at weakest point of Range of Motion
Plyometrics
involves a sudden eccentric stretching action of the muscles followed by a forceful concentric contraction of those same muscles
Muscle Strength Training Options
Reps, Sets, Resistance
Reps
number of times you repeat the lift without rest and with the same weight selection
Sets
groups of reps performed in a single attempt
Resistance
given load or weight applied against a muscle during a specific exercise
Safety Considerations for Exercising
dont exercise alone; dont hold breath when lifting overhead; dont hyperventilate; keep hands dry; warm up
FIT formula for muscle strength
3 days/wk; 70% 1RM; 2-5 sets of 4-10 reps
FIT formula for muscle endurance
3+ days/wk; 40-60% 1RM; 2-4 sets of 20-40 reps
FIT formula for muscle hypertrophy
3+ days/wk; 70-85% 1 RM; 3-6 sets of 6-10 reps
FIT formula for muscle tone
3+ days/wk; 50-70% 1RM; 2-3 sets of 15-20 reps
Body Composition
how much of your body weight comes from fat mass and how much from lean mass (LBM); influenced by sex, age, diet, exercise
Lean Body Mass (LBM)
weight of the body, less the fat weight; consists of tissues other than body fat, e.g. muscle tissue, heart, liver, etc); LBM is primary determinant of body's basal metabolism rate; major influence on energy requirements and nutrient needs
Obesity
body weight more than 20% over standard (men >25%; women>30%)
Obesity (35% adults are obese)
higher risk heart attack; high blood pressure common; narrowing of arteries;
3 Body types
endomorph, mesomorph, ectomorph
Endomorph (endo = within)
round build, gain weight easily; hourglass figure
Mesomorph (meso = middle)
muscular with low percentage of body fat
Ectomorph (ecto = outer,external)
typically tall and thin
Mesoendomorph
new category; good musculature but higher percent of body fat
Overfat
excess of fat weight
Overweight
people with body wt. above 10% above standard height/weight tables; 65% Americans are overweight
Obese
Men 25%, women 30% over height/weight tables
Dominant Factor of Obesity
Inheritance
Body Mass Index (BMI)
calculated by dividing weight by height
Facts about Body Fat
75 BB fat cells; size of fat cells can be shrunk, but cells cannot be eliminated; fat cells increase in number w/obesity, age and inactivity; for every liter of oxygen consumed, 5 calories of fat are burned; burning 3500 calories + 1 lb weight loss
Creeping Obesity
most people will gain 1 lb/yr after age 25
3500 calories
# calories you need to burn for one pound weight loss
Essential fat
needed for normal physiological functions; about 3% total fat in men and 12% in women
Stored fat
stored in adipose tissue, subcutaneous tissue and between organs (visceral); men store fat around waist and women around hips and thighs
Factors influencing weight fluctuation
Resting metabolic rate (RMR); fat metabolizing enzyme activity; set point theory; fat cell number
RMR
energy expended while resting (also known as BMR); directly related to oxygen consumption; sedentary people have low RMR
Factors Affecting RMR
Age (after 20, RMR decreases 2-% per decade), Height (tall, thin people have higher RMR) , Gender (Men have 10-15% higher RMR), Dieting (RMR drops during fasting), Environmental Temps, Exercise
Energy Expenditure
60-70% ttl energy ouput is = rest; 20-30% = physical activity; 10% = digestion
Strategies for Weight Mgmt
combination of aerobic exercise and weight training most effective for reducing fat; to burn excess fat, lengthen workouts (1st 20 min of aerobic burns carbs; 2nd 20 minutes body burns fat stores)
LBM formula
body wt x body fat% = lbs of fat; to find lean body mass - body wt - lbs of fat = LBM
LBM formula
BW x BF% = # lbs fat; BW = # Fat = LBM
