Priority Lifestyles for Good Health:
|
Three priority areas:
1) Physical Activity, 2) Healthy Eating, 3) Managing Stress Reasons why these lifestyles are especially critical: They affect the lives ofall people Many people can make improvements Small changes can havea major impact on individual and public health |
|
Value of Fitness Assessments:
|
Indicate areas needed for improvement in health, fitness, or performance
Provide baseline marker to track progress in exercise programs Promote personal knowledge about skills and abilities |
|
Factors to Consider Prior to Physical Activity:
|
Medical readiness for physical activity (PAR-Q) Physical Activity Readiness Questionaire.
Other Pre-participation issues? medications, injuries, health history, family health issues, surgeries, cancer, pregnancy. Proper equipment and shoes |
|
PRE-PARTICIPATION SCREENING : MAJOR COMPONENTS:
|
MEDICAL HISTORY
MEDICATION (could affect heart rate) INFORMED CONSENT (keeps liability on athlete & protects trainer) WARNING OF CATASTROPHIC INJURY (for tests & activites) WAIVER OF LIABILITY CARDIOVASCULAR RISK STRATIFICATION PAR-Q RISKO (AHA) MEDICAL EXAMINATION (WHEN NECESSARY) (PARmedX) Medical clearance form 4 MET Capacity = 3.5 ml/kg (bw) is 4 X's resting expenditure. |
|
ACSM Guidelines:
|
Because of increased risk, certain individuals should be given a graded exercise test prior to performing vigorous exercise:
Individuals with CHD risk factors(age, family history, high cholesterol, high blood pressure, sedentary lifestyle, smoker, obese, prediabetic) If a patient has 2 or more risk factors they are limited to moderate intensity & have to have physician clearance. Sub-max test would also require physician clearance. BMI- greater than 30 is obese. |
|
Clinical Exercise Test(Stress Test):
|
A stress test can determine whether a person can safely perform exercise.
|
|
PAR-Q:
|
P HYSICAL
A CTIVITY R EADINESS Q UESTIONNAIRE |
|
Wearing Good Shoes is Important:
|
Running
Court Aerobic Walking Tennis Cross trainers |
|
Factors to Consider During Daily Physical Activity:
|
Importance of warm-up and cool-down for reducing risk of injuries and soreness
Environmental factors |
|
Survey the physical environment prior to teaching an activity:
|
Evaluate exercise area for potential issues.
Unsafe conditions? Lighting Debris Surface Cracks Slippery surfaces Unsafe temperature/humidity? ACSM has guidelines. Temperature/dry climate: if someone is not acclimated they should not run in dry/high temp until acclimated. Unsafe equipment? Weight room Proper attire for participants? Not tight or unbreathable |
|
Components of a Workout:
|
1. Warm-up Athlete vs. non-athlete: needs to be sport-specific. dependent on the type of activity being performed. No static stretching for an athlete pre-exercise. Stretching could decrease power & stamina.
2. Workout 3. Cool-down: needs to be longer form more intense workouts. C.V. warm-up. Involve large muscle movements. Return HR & BP to close to resting rate. |
|
Benefits of a Warm-up:
|
Elevate intramuscular temp.
Prepare cardiovascular system: increase blood flow to heart & temperature. Prepare metabolic system: enzymes dependent on energy synthesis depends on temp. & PH levels. Prepare musculoskeletal system |
|
Components of a Warm-up:
|
Cardiovascular component
Flexibility component Age effects the needs of a longer warm-up. Dynamic stretching could be a part of warm-up for athletes such as soccer & football players. 4-10 minutes minimum warm-up but needs to be much longer for martial arts & rigorous exercises or sports. |
|
Benefits of a Cool-down:
|
Reduces blood pooling: by maintaining active recovery.
Promotes recovery Minimizes muscle soreness Should last same amount of time as warm-up. |
|
Signs of Overexertion:
|
OBSERVATION:
Profuse sweating Pallor: pale skin & sign of poor profusion (energy expenditure) Cyanosis (turn blue) Ataxia (change in movement pattern) Stop sweating silent eschemia (not enough oxygen to the heart but the person doesn't know it) Ex. Iron man comp. SUBJECT OBSERVES: Nausea Dizziness Light headed Volitional exhaustion CHEST PAIN Feeling faint. |
|
Exercising Safely in Different Environments:
|
Heat- higher HR
Cold- frostbite Altitude-less oxygen available & increase HR & lose water more rapidly. Pollution- inner city. Runners have a high volume of lead in their blood. |
|
VO2 Max =
|
ml/kg/min.
|
|
Heat Related Illness:
|
Heat cramps
Heat exhaustion Heat stroke The severity of heat related illness increases with the degree of dehydration. |
|
Exercise in the Heat:
|

|
Exercise in the Cold:
|
Wind-chill factor
Dress in layers |

Cold, dry air promotes dehydration Acute mountain sickness |
|
Pollution Induces:
|
Ozone
Pollutants Allergies |
|
DOMS:
|
Delayed-onset muscle soreness from micro tears in the muscles.
24-48 hrs after intense exercise. NOT caused by lactic acid. Caused by microscopic muscle tears resulting from excessive loads on the muscles. Occurs when you violate the principle of progression. |
|
Common Injuries:
|
Sprains - ligaments connect bone to bone
Strains - muscles/tendons connect muscle to bone Muscle cramps - due to dehydration, need to replace electrolytes, bananas can be eaten, can take magnesium or potassium which are electrolytes. |
|
Treatment of Injuries:
|
R Rest
I Ice C Compression E Elevation |
|
Attitudes about Physical Activity:
|
Knowing the most common reasons for inactivity can help you avoid sedentary living.
I don’t have time. It’s too inconvenient. I do not enjoy it. Knowing the reasons people give for being active can help you adopt positive attitudes toward activity. I do activity for health, wellness, and fitness I do activity to improve appearance I do activity because I enjoy it. |

Principles of Exercise Testing:
|
Validity – the extent to which the test measures what it purports to measure

|
|
Health Related Fitness:
|
Cardiovascular endurance
Muscular endurance Muscular strength Flexibility Body composition |
|
Skill Related Fitness:
|
Agility
Balance Coordination Speed Power Reaction time |
|
Cardiovascular Fitness:
|
"Cardio" = heart

|
Synonyms of Cardiovascular Fitness:
|
Aerobic fitness
Cardiovascular endurance Cardiorespiratory fitness |
|
Cardiovascular System:
|
Muscles send deoxygenated blood to heart
Heart sends deoxygenated blood to lungs Lungs oxygenate the blood Heart sends oxygenated blood to body |
|
Characteristics of Blood Vessels:
|
Arteries pump oxygenated blood and have muscular, elastic walls that promote good circulation
Veins carry de-oxygenated blood and rely on pumping action of muscles to move blood |
|
Pulse:
|
Arteries have elastic walls andstretch as the bloodmoves throughthe vessel. This is what is felt as the pulse.
