Skill-Related Fitness Components • Reaction time (amount of time needed to move once you realize you have to act) • Power (use of strength quickly) • Coordinatio n (ability to use senses with body parts or use 2+ body parts together) • Speed (ability to perform a movement or cover a distance in a short time-frame) • Agility (change of body quickly and control body’s movements) • Balance (maintaining posture while standing still or moving)
5 Health-Related Fitness Components • Cardiovascular Endurance • Muscular Strength • Muscular Endurance • Flexibility • Body Composition **Health is more important than Skill because it AFFECTS EVERYONE!!**
3 Fitness Training Principles • 1. Overload– doing more than your body is used to doing • How to apply overload • Frequency – how often (# days/week) • Intensity – how hard (heart rate OR amount of weight) • Time – how long (minutes OR sets and reps) • 2. Progression– gradually increasing workout • 3. Specificity- choose activities that focus on the Health-Related Fitness Component you want to work
Cardiovascular Fitness • Cardiovascular System – Heart (muscle), blood vessels (arteries = AWAY & veins = TO), blood (oxygen) • Respiratory System – lungs and air passages that bring air (O2) from outside the body to the lungs, CO2 leaves lungs CV & Respiratory Systems work together to bring body cells oxygen (needed for body to function) and get rid of waste products.
Cardiovascular Fitness, cont. • Exercise helps the body systems work more efficiently and effectively. The more you exercise, the more effective your body becomes at delivering O2to body cells (Muscle cells need O2 to contract) • Calories/week on exercise = 2000-3500
Physical Activity & Brain Function • August 2001 Study published in the Annuals of Behavioral Medicine • EXERCISES increases growth of brain cells in hippocampus (part of the brain involving learning & memory), which slows with stress hormones • EXERCISE increases blood circulation (oxygen & glucose) to brain
Physical Activity & Brain Function • Increased breathing and heart rate = more blood to brain • Increased energy production with waste removal • IMPROVED MEMORY, LEARNING ABILITY, CONCENTRATION, and ABSTRACT REASONING • Releases ENDORPHINS responsible for “runner’s high” • Increased EXECUTIVE FUNCTIONING (planning, organization, ability to multi-task)
Physical Activity & Brain Function • Research performed by Jon Ratey, Clinical Associate Professor of Psychiatry at Harvard Medical School • Exercise increases CEREBRAL BLOOD FLOW, spurring cell growth • Stimulates more receptors for insulin, which makes for an improved use of glucose, STRENGTHENING cells • Exercise stimulates the PRODUCTION of a protein called BDNF (brain-derived neurotrophic factor) - “MiracleGro for the Brain” • Promotes neuroplasticity, which enables brain cells to be trained to a different state and to take in new information • Helps prime the brain for learning by helping person stay focused, alert, aroused, and less fidgety
Physical Activity & Brain Function Jon Ratey Research • EXERCISE improves FOCUS & ATTENTION (improves ability to help you increase in test scores) • EXERCISE decreases STRESS & ANXIETY & DEPRESSION • Wards off effects of stress and even reverses the effects • EXERCISE improves MOOD • EXERCISE helps control symptoms of ADHD (exercise, take meds 1 hr later… eventually need for meds may decrease) • EXERCISE improves MEMORY in old age
Physical Activity and Brain Function • BRAIN = MUSCLE • If you don’t USE it, you will LOSE it! • It needs stimulation (exercise) to grow!
Warm-up & Cool- Down • Heart • Muscles WHY? • Warm-up = increase blood flow, increase body/muscle temperature, increase OXYGEN throughout body • Cool-down = prevent blood pooling and fainting, heart rate should drop to 100 bpm after 10 minutes (RECOVERY HR) • BOTH should last 5-10 minutes
Benefits of Cardiovascular Fitness • Decreased risk of heart disease • Decreased risk of heart attack • Decreased blood pressure, resting HR • Decreased chance for life diseases (diabetes) • HIGH High Density Lipoproteins, LOW Low-Density Lipoproteins • Cholesterol- fatty substance found in meats, dairy products, and egg yolks. • Carried through bloodstream by particles called lipoproteins. • HDL - carries excess bad cholesterol out of bloodstream (GOOD) • LDL - carries cholesterol which stays in body and contribute to numerous health issues (BAD) • Reduces FIBRIN in blood (clotting) • Adds YEARS to your life
Cardiovascular Endurance • Definition: The ability of the heart, blood vessels, and lungs to supply oxygen and necessary fuel to muscles during exercise • SPECIFICITY: Running, Biking, Swimming, etc • What is YOUR CV Fitness level? • Assessed with PACER TEST or
Fitness Training Principles & CV • How do we APPLY OVERLOAD to CV Endurance? (Healthy Fitness Zone) • F: 3-6 days/week • I: 60-80% HR Max (target heart rate range) • T: 20-60 minutes or more • PROGRESSION?? SPECIFITY?? • How much is ENOUGH to BENEFIT? • Follow the HEALTHY FITNESS ZONE • HR MAX = Maximum # times heart should beat/minute • 220-age
Target Heart Rate Zone220-age = HR Max RESTING HEART RATE = ____ Actual Training Zone – Karvonen Method Estimate Training Zone using Percentages HR Max – Resting HR(RHR) = Working heart rate(WHR) (WHR) x .60 = ____ + RHR= Low end (WHR) x .80 = ____+ RHR = High end TARGET HR RANGE: Low end = High end = (HR Max) x .60 = low end (HR Max) x .80 = high end TARGET HR RANGE: Low end = High end =
4 Characteristics of CV Activities • Large Muscle group movement • Rhythmic movement - pacing • Aerobic activity - body needs oxygen for extended activity • Continuous - THR Range met for 20+ minutes
AEROBIC VS. ANAEROBIC • AEROBIC Exercise • Activity that is dependent upon the heart, lungs, and blood vessels to transport OXYGEN to use as fuel. • Oxygen is replaced as quickly as it is used • Generally large muscle activities that are sustained for a long period of time • Examples: running, walking, biking
AEROBIC VS ANAEROBIC • ANAEROBIC • Short bursts of intense exercise,20-30 Seconds • Uses immediate energy stored in muscles • Examples: sprinting, single rep weight lifting
Body Composition • Body Fatness - % of total body that is fat tissue (unused calories stored as FAT) • Body Composition – all tissues that make up the body (lean body tissue - muscles, bones, skin, organs vs. fat) **Healthy Range - Males 10%-25% Females 18%-32%
Influences on Body Fatness • Heredity • Metabolism (amount of energy/calories the body uses to keep you living) • SLOWS as we age • Maturation • Early fatness • Diet • Physical Activity
Why we NEED body fat • Fat is an INSULATOR (heat and cold) • Shock ABSORBER (protects organs and bones) • Uses VITAMINS effectively • STORED ENERGY • Note – bulimia (bingeing/purging) & anorexia
How do we APPLY OVERLOAD to Body Composition? Healthy Fitness Zone • Physical Activity • F = 3-6 days/week • I = 40-60% HR Max (Target HR range) • T = 30+ minutes • PROGRESSION?? SPECIFICITY??? • Diet • F = 3 meals or 4-5 small meals • I = To lose 1 lb, eat 3500 cal < normal To gain 1 lb, eat 3500 cal> normal To maintain, eat & burn same cal. • T = No more than 1-2 lbs per week • Females = 2000-2500cals/Males = 2500-3000cals
Measuring Body Composition • Bioelectrical Impedance • (how we measure) • Hydrostatic Weighing • Skinfold
3 Body Types • Ectomorph- Small “delicate” frame and bone structure, Flat chest, Small shoulders, Thin, Lean muscle mass, Finds it hard to gain weight, Fastest metabolism • Mesomorph –Athletic, Hard body with well defined muscles, Rectangular shaped body, Strong , Gains muscle easily, Gains fat more easily than ectomorphs • Endomorph - Soft and round body, Gains muscle and fat very easily, Is generally short and “stocky”, Round physique, Finds it hard to lose fat, Slow metabolism
MUSCULAR ENDURANCE COMPARISONS • Cardiovascular Fitness – heart & lungs function efficiently during vigorous activity (muscles have to work too, but HEART is MOST important!) VS • Muscular Endurance – the ability to contract muscles repeatedly without tiring (heart working, but not the focus)
MUSCULAR ENDURANCE • COMPARISONS Muscular Endurance: the ability to contract muscles repeatedly without tiring More reps - Less weight vs Muscular Strength: amount of force muscle can exert Less reps - More weight
BENEFITS OF M. ENDURANCE • Strengthen Bones • Work longer without tiring • Good posture • Increase lean body mass • Decrease fat • Decrease chance for back & muscle pain or injury
Anatomy – Muscles and Bones • Skeletal Muscle – voluntary muscles; attaches to bones and makes movement possible – used to do physical activity • Muscle fibers – muscle cells that are long, thin, and cylindrical-shaped • Slow-twitch (Type 1)– contract slowly, ie long distance running • Fast-twitch (Type 2b)– contract quickly, ie sprinting • Intermediate-twitch (Type 2a) – use both anaerobic and aerobic means
Muscle contractions (shorten/lengthen muscle) • Isometrics – when muscles contract and pull force in opposite direction/ no joint movement • Isotonics – when muscle contracts, it pulls on bones and produces movement • CONCENTRIC - MUSCLE SHORTENS • ECCENTRIC - MUSCLE LENGTHENS • *Hypertrophy – increase in muscle size
Terms • Rep Max – most amount of weight you can do ONE TIME • Repetitions - # of consecutive times you do an exercise • Set - group of repetitions
M. Endurance Activities • Calisthenics – body weight resistance • Resistance Training – force acting against your muscles, i.e.free weights or machines • Circuit Training – combination of calisthenics and resistance training
HOW DO WE APPLY OVERLOAD TO M. ENDURANCE?? (Healthy Fitness Zone) • F – 3-5 days/week • I – 30-50% 1 rep max • T – 4 sets, 12-20 reps • PROGRESSION?? • SPECIFICITY?? • How do WE measure Muscular Endurance? CURL-UPS!!
M. Fitness Training Guidelines • Proper warm-up & cool-down • Breathing (exhale on contraction) • Spotters • NO MAX LIFTS! (bones not strong enough) • Avoid powerlifting • Form/technique • NO fast movements • NO COMPETITIONS!! • WORK OPPOSITE MUSCLE GROUPS
MUSCULAR STRENGTH • Amount of force a muscle can exert • Measured with PUSH-UPS TEST • MUST BE BALANCED WITH FLEXIBILITY TO MAINTAIN HEALTHY MUSCLES
Benefits of Muscular Strength • Work and play without fatigue • Improved posture • Prevents health-related problems & muscle injury • Strengthens bones
HOW DO WE APPLY OVERLOAD TO M. STRENGTH?? (Healthy Fitness Zone) • F – 3-5 days/week • I – 60-90% 1 rep max (TEENS = 60-75% rep max) • T – 3 sets, 4-8 reps (TEENS = 7-10 reps) • PROGRESSION???? SPECIFICITY????
More M. Fitness Exercises • Isometrics & Isotonics • Isokinetics – exercise where speed and resistance are controlled (computer-operated) • Plyometrics- power training (box jumps) BEST AFTER TEEN YEARS • Calisthenics – body weight (push-ups, sit-ups) • Weight/Resistance Training– lifting weight to build strength • PRE (Progressive Resistive Exercise)– gradual increase in resistance training exercises applying the training principles BEST WAY • Body Building – type of WT athletes use to develop large muscles • Muscle Bound – only focusing on certain muscles • STEROIDS – side effects (acne, facial hair in girls, decreased male hormone functioning)
M. Fitness Training Guidelines • Proper warm-up & cool-down • Breathing (exhale on contraction) • Spotters • NO MAX LIFTS! (bones not strong enough) • Avoid power lifting • Form/technique • NO fast movements • NO COMPETITIONS!! • WORK OPPOSITE MUSCLE GROUPS
Agonist vs. Antagonist - OPPOSITES • AgonistvsAntagonist • Agonist – muscle contracting to do work • Antagonist – muscle being stretched when AGONIST is contracting • EXAMPLES: biceps vs. triceps, quads vs. hamstrings
Flexibility • Range of Motion (ROM) – amount of movement you can make at a joint (elbow, knee, shoulder) • Flexibility – the ability to move a joint through a full ROM • *Measured with Sit & Reach Test
Benefits of Flexibility • Improved function (daily activities) • Females tend to be more flexible than males • Improved health & wellness • Improved posture • Prevents injury and muscle soreness • Muscle relaxation
Characteristics that affect Flexibility • Body build – how you are put together • Hypermobility – ability to extend a joint past a straight line, as if bending backwards (elbow, knee, wrist) • More prone to joint injuries • May develop arthritis (inflammation in a joint) • Joint laxity – looseness in a joint (place where bones come together) TENDONS? • When joint allows bones to move in ways other than intended • Strength and Flexibility – must be balanced to maintain health; tight muscles pull on body
Types of Flexibility Exercises • ROM Exercises – flexibility exercises that are used to maintain ROM already present (NO PAIN), ie. Arm circles • Stretching exercises – increase ROM by stretching further than current ROM • Static Stretching – stretch slowly as far as you can without pain until you feel a “pull,” then hold for 15-30 seconds • PNF (ProprioceptiveNeuroMuscular Facilitation) – variation of static stretching; involves the using body’s reflexes to relax muscles before stretching, to stretch it further • Ballistic – series of quick, but gentle bouncing motions that aren’t held for a long time (only for regular exerciser)
