This document discusses the components of physical fitness and provides guidelines for exercise. It covers the six components of health-related fitness: cardiorespiratory fitness, muscular strength, muscular endurance, flexibility, body composition, and metabolic fitness. It recommends that adults get at least 150 minutes per week of moderate exercise or 75 minutes of vigorous exercise to gain substantial health benefits. The document also discusses how to design aerobic and strength training workouts, different types of exercises, flexibility, and mind-body approaches like yoga and Pilates.
Test taking anxiety is a very common issue among college students. Research indicates that physical activity/exercise may help diminish the symptoms of test taking anxiety. Current research has studied the relationship between varying forms of exercise and test-taking anxiety using anxiety measures such as the State Trait Anxiety Inventory (STAI). The purpose of this study was to examine the effects of physical activity/exercise on self-reported test taking anxiety and anxiety scores on the STAI. A total of 267 college students completed an informed consent form preceding an online survey instrument. The survey collected self-reported information such as grade point average, text-taking anxiety, and physical activity/exercise habits; subjects also completed the STAI. Students who participate in moderate-to-high physical activity/exercise scored significantly lower (representing lower anxiety levels) on the STAI in comparison to students who participate in moderate-to-low physical activity/exercise. This would suggest that moderate-to-high physical activity/exercise may reduce academic anxiety such as test-taking anxiety in college students.

Secret to live 100 years get it today and see the difference
<<<https://www.digistore24.com/redir/347298/Kewan17>>>
Okinawa is an island located south of mainland Japan and is known as the site of the largest U.S. military amphibious operation during the Second World War. Today, it is better known as the source of the “Okinawa Diet” — a simple yet effective weight loss program. The Okinawa Diet is about eating plenty of plant-based food which include large quantities of tofu and locally grown vegetables. This eating plan also prescribes the consumption of different varieties of fish rich in Omega-3 fatty acids, seaweed, and other organic products that are high in protein, rich in calcium, and low in fat. In fact, it is not unusual to find Okinawans who are at least 100 years old. The island has been recognized as having the most number of centegenarians in the entire world. To this day, the incidence of heart disease, breast cancer, prostate cancer is still rare in the island.
The growing problem of being overweight and obese in the United States has made the Okinawan Diet very appealing. Many overweight individuals have tried taking a diet pill to minimize hunger pangs and , in the process, reduce food intake. Other weight loss diet pill formulas work by preventing the absorption of fat into the body, most of which come from fat-laden meats.
Since most Okinawans rarely eat meat, weight gain is hardly a problem. It is highly unusual to see overweight or bulging Okinawans. Most of them have retained the short but slim physical appearance of their ancient ancestors who were mostly hardy fisher folk and farmers. The key to the effectiveness of the Okinawan Diet is the philosophy that is best encapsulated in the phrase, “food as tonic, food as medicine.” Islanders have been strongly influenced by the food culture of China, Korea, and Mainland Japan — all which emphasized the medicinal and therapeutic value of certain food groups. In many Okinawan homes, the mother or the person who prepared the food usually serves the meal by saying, “Please eat this. This food is good for healing this or that illness. Eating is good for you.” After the meal, the people who ate the food would say, “Kusuinatan!” The word “kusuinatan” is an Okinawan term which means, “The food is good. My body feels good. Food is like medicine.”

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Joy of Fitness
LectureOutline
I. What Is Physical Fitness?
A. Introduction
1. Physical fitness is the ability to respond to routine physical demands, with
enough reserve energy to cope with a sudden change.
2. The six health-related components of physical fitness are:
a. Cardiorespiratory Fitness
i. The ability of the heart to pump blood through the body efficiently.
b. Muscular Strength
i. The force within muscles, measured by the absolute maximum
weight that you can lift, push, or press in one effort.
c. Muscular Endurance
i. The ability to perform repeated muscular effort; it is measured by
counting how many times you can lift, push, or press a given
weight.
d. Flexibility
i. The range of motion around specific joints.
e. Body Composition
i. The relative amounts of fat and lean tissue (bone, muscle, organs,
water) in the body.
f. Metabolic Fitness
i. Refers to reduced risk for diabetes and cardiovascular disease,
which can be achieved through a moderate-intensity exercise
program.
B. Fitness and the Dimensions of Health
1. Instructors, coaches, and consumers are pursuing a broader vision of total
fitness that encompasses every dimension health:
a. Physical
b. Emotional
c. Social
d. Intellectual
e. Occupational
2. Chapter 7 – The Joy of Fitness
f. Spiritual
g. Environmental
C. Working Out on Campus
1. Only half of undergraduates—54.2 percent of men and 48.8 percent of
women—meet the current recommendations for moderate or vigorous
exercise.
2. College men are generally more active than women.
3. As students progress from their first to fourth year of studies, they
exercise less.
4. In research on influences on students’ health behaviors, peer pressure to
exercise (for men more than women), and having an exercise partner, a
flexible class schedule, access to fitness facilities, and a sense of being
stressed all increase physical activity.
II. Physical Activity and Exercise
A. Introduction
1. Physical activity refers to any movement produced by the muscles that
results in expenditure of energy.
2. Exercise is a type of physical activity that require planned, structured, and
repetitive bodily movement with the intent of improving one or more
components of physical fitness.
B. The Benefits of Exercise
1. Longer Life
a. In various studies, physical activity increased life expectancy by 1.3 to
5.5 years.
2. Healthier Heart and Lungs
a. Sedentary people are about twice as likely to die of a heart attack as
people who are physically active.
b. Exercise makes the lungs more efficient.
c. Cardiorespiratory fitness declines more rapidly after age 45, but
exercising regularly, maintaining a healthy weight, and not smoking
can help maintain cardiorespiratory health throughout life.
3. Protection against Cancer
a. Physical activity may reduce the risk of several cancers, including
breast, colon, endometrial, prostate, and possibly pancreatic.
b. It may also help to prevent cancer by regulating sex hormones, insulin,
and prostaglandins and by enhancing the immune system.
c. The combination of excess weight and physical inactivity may account
for a quarter to a third of all breast cancer cases.
4. Better Bones
3. Chapter 7 – The Joy of Fitness
a. Osteoporosis is a condition in which bones become increasingly soft
and porous, making them susceptible to injury.
b. Exercise during adolescence and young adulthood may prevent bone
weakening and fractures in old age.
5. Lower Weight
a. Exercise may help to control weight by suppressing appetite.
6. Better Mental Health and Functioning
a. Exercise is an effective – but underused – treatment for mild to
moderate depression and may help in treating other mental disorders.
b. Lifelong fitness may protect the brain as we age.
7. Benefits for Students
a. In research on more than 1.2 million men, strong cardiorespiratory
fitness in young adulthood was associated with higher intelligence,
better grades, and greater success in life.
8. Brighter Mood and Less Stress
a. Exercise boosts mood, elevates self-esteem, increases energy, reduces
tension, improves concentration and alertness, and relieves stress.
9. A More Active and Healthy Old Age
a. Exercise slows the changes that are associated with advancing age
such as loss of lean muscle, increase in body fat, and decrease in work
capacity.
10. Enhanced Sexuality
a. By improving physical endurance, muscle tone, blood flow, and body
composition, exercise improves sexual functioning.
C. Exercise Risks
1. Hypertrophic cardiomyopathy (HCM) is a genetic disease that results in
thickening or enlargement of the heart that affects up to 1 in 500 people.
a. HCM accounts for 40 percent of all deaths on athletic fields in the
United States.
2. College students who play contact sports such as football may be at risk of
a condition called chronic traumatic encephalopathy (CTE), the result of
multiple mild head injuries.
III. Physical Activity Guidelines for Americans
A. Overview
1. Recommendations from the U.S. Department of Health and Human
Services Physical Activity Guidelines for Americans:
a. All adults should avoid inactivity.
4. Chapter 7 – The Joy of Fitness
b. For substantial benefits, adults should do at least 150 minutes a week
of moderate-intensity aerobic activity or 75 minutes a week of
vigorous-intensity aerobic activity.
c. For additional and more extensive health benefits, adults should
increase their aerobic physical activity to 300 minutes a week of
moderate-intensity aerobic activity or 150 minutes a week of vigorous-
intensity aerobic activity.
d. Adults should also do muscle-strengthening activities on two or more
days a week.
2. The American College of Sports Medicine (ACSM) and the American
Heart Association (AHA) guidelines recommend:
a. Moderately intense cardiorespiratory exercise 30 minutes a day, 5 days
a week or
b. Vigorously intense cardiorespiratory exercise 20 minutes a day, 3 days
a week and
c. 8 to 10 strength-training exercises, with 8–12 repetitions of each
exercise, twice a week.
B. How Much Exercise Is Enough?
1. The minimum amount of exercise required for a significant lowering of
the risk of premature dying is 500 MET minutes of exercise a week.
2. A single MET, or metabolic equivalent task, is the amount of energy a
person uses at rest.
IV. The Principles of Exercise
A. Overload Principle
1. Requires a person exercising to provide a greater stress or demand on the
body than it’s usually accustomed to handling.
2. Progressive overloading—gradually increasing physical challenges—
provides the benefits of exercise without the risk of injuries.
B. FITT
1. The acronym FITT sums up the four dimensions of progressive overload:
frequency, intensity, time, and type.
a. Frequency
i. Health officials urge Americans to engage in moderate-intensity
aerobic activity most days, and resistance and flexibility training
two or three days a week.
b. Intensity
i. Exercise intensity varies with the type of exercise and with personal
goals.
c. Time (Duration)
5. Chapter 7 – The Joy of Fitness
i. The American College of Sports Medicine (ACSM) recommends 30
to 45 minutes of aerobic exercise, proceeded by 5 to 10 minutes of
warm-up and followed by 5 to 10 minutes of stretching.
d. Type (Specificity)
i. The specificity principle refers to the body’s adaptation to a
particular type of activity or amount of stress placed upon it.
C. Reversibility Principle
1. The reversibility principle is the opposite of the overload principle. If you
stop exercising, you can lose as much as 50 percent of your fitness
improvements within two months.
V. Improving Cardiorespiratory Fitness
1. Aerobic exercise, which improves cardiorespiratory endurance, can take
many forms, but all involve working strenuously without pushing to the
point of breathlessness.
2. Anaerobic exercise involves activities in which the amount of oxygen
taken in the body cannot meet the demands of the activity.
A. Monitoring Intensity
1. Resting heart rate is the number of heartbeats per minute during
inactivity.
2. Target Heart Rate
a. The ACSM recommends working at 50 to 85 percent, depending on
your level of fitness, of maximum heart rate to get cardiorespiratory
benefits from your training.
3. The Karvonen Formula
a. The Karvonen formula is another mathematical formula for
determining your target heart rate (HR) training zone.
4. Rating Perceived Exertion (RPE)
a. A self-assessment scale that rates symptoms of breathlessness and
fatigue.
B. Designing an Aerobic Workout
1. An aerobic workout should include:
a. Warm-up
i. The ACSM concluded that preparing for sports or exercise should
involve a variety of activities and not be limited to stretching alone.
b. Aerobic activity
i. The current recommendation is to keep moving for 30 to 60
minutes, either in one session or several briefer sessions, each
lasting at least 10 minutes.
c. Cool-down
6. Chapter 7 – The Joy of Fitness
i. Ideally, you should walk for 5 to 10 minutes at a comfortable pace
before you end your workout session.
C. Aerobic Options
1. Stepping Out: Walk the Walk
a. Walking may reduce the risk factors for cardiorespiratory disease, such
as insulin resistance, as much as vigorous activity does.
2. America on the Move
a. The national “America on the Move” program recommends 10,000
steps each day.
b. You take about 5,000 steps just to accomplish your daily tasks. Adding
about 2,000 steps brings you to a level that can improve your health
and wellness. Another 3,000 steps can help you lose excess pounds and
prevent weight gain.
3. Jogging and Running
a. To enhance aerobic fitness, long, slow, distance running is best.
b. To improve speed, try interval training which is repeated hard runs
over a certain distance, with intervals of relaxed jogging in between.
4. Other Aerobic Activities
a. Swimming
b. Cycling
c. Spinning
d. Cardio kick-boxing
e. Rowing
f. Skipping rope
g. Stair climbing
h. Stair-climbing
i. Inline skating
j. Tennis
k. Zumba
VI. Building Muscular Fitness
A. Overview
1. Strength workouts are important because they enable muscles to work
more efficiently and reliably.
2. Muscular strength is the maximal force that a muscle or group of muscles
can generate for one movement.
3. Muscular endurance is the capacity to sustain repeated muscle actions.
4. The best way to reduce your body fat is to add muscle-strengthening
exercise to your workouts.
B. Muscles at Work
7. Chapter 7 – The Joy of Fitness
1. Overloading is demanding more of muscles than you usually do.
a. To develop strength, do a few repetitions with heavy loads.
b. To increase endurance, do many more repetitions with lighter loads.
2. In an isometric contraction, the muscle applies force while maintaining an
equal length.
3. An isotonic contraction involves movement, but the muscle tension
remains the same.
4. Isokinetic contraction is a constant speed contraction.
C. Designing a Muscle Workout
1. A workout with weights should exercise your body’s primary muscle
groups:
a. Deltoids (shoulders), pectorals (chest), triceps and biceps (back and
front of upper arms), quadriceps and hamstrings (front and back of
thighs), gluteus maximus (buttocks), trapezius and rhomboids (back),
and abdomen.
2. A weight-training program is made up of reps (the single performance, or
repetition, of an exercise, such as lifting 50 pounds one time) and sets (a
set number of repetitions of the same movement).
3. Free Weights vs. Machines
a. Free weights offer great versatility for strength training and can be
used for a variety of exercises to work specific muscle groups.
b. Strength-training machines
i. Can ensure correct movement which helps protect against injury
ii. Isolate specific muscles which is good for rehabilitating an injury or
strengthening a specific body part
iii. Can tax muscles in ways that a traditional barbell cannot
D. Recovery
1. The ACSM recommends a minimum of 8 to 10 exercises involving the
major muscle groups two to three days a week
2. Never work a sore muscle.
3. Allow no less than 48 hours, but no more than 96 hours, between training
sessions.
E. Core Strength Conditioning
1. Core strength refers to the ability of the muscles to support your spine and
keep your body stable and balanced.
2. The major muscles of your core include the transverse abdominis, external
and internal obliques, and rectus abdominis.
F. Muscle Dysmorphia
1. Also referred to as “bigorexia,” or “reverse anorexia” is a condition that
primarily affects male body builders.
8. Chapter 7 – The Joy of Fitness
2. Its primary characteristics include giving up important activities to work
out, avoiding situations that include body exposure, preoccupation with
body size, and continued use of exercise, diet, or performance-enhancing
substances despite physical or psychological harm.
G. Drugs Used to Boost Athletic Performance
1. The risks include cancer, liver disease, blood diseases, severe arthritis, and
sexual dysfunction.
2. Anabolic steroids are synthetic derivatives of the male hormone
testosterone that promote growth of skeletal muscle and increase lean
body mass.
a. Taking them to improve athletic performance is illegal.
b. Use may lead to liver tumors, jaundice, fluid retention, high blood
pressure, decreased immune function, and severe acne.
c. In men they may cause shrinking of the testicles, reduced sperm count,
infertility, baldness, and development of breasts.
d. Women may experience growth of facial hair, changes or cessation in
menstrual cycle, enlargement of the clitoris, and a deepened voice.
3. Androstenedione – this testosterone precursor is normally produced by
the adrenal glands and gonads.
a. It is a controlled substance, and its use is illegal.
4. Creatine is an amino acid made by and stored by the body and stored
predominantly in skeletal muscle.
a. It may increase strength and endurance.
5. GBL (gamma butyrolactone) is marketed as a performance enhancer and
muscle builder.
6. Ergogenic aids are substances, such as caffeine, baking soda, and glycerol,
used to enhance energy and provide athletes with a competitive edge.
7. Human growth hormone increases lean body mass but does not affect
exercise capacity or aerobic endurance.
8. Erythroprotein (EPO) is a hormone that increases red blood cell
production and improves endurance.
VII. Becoming More Flexible
A. Overview
1. Flexibility is the characteristic of body tissues that determines the range of
motion achievable without injury at a joint or group of joints.
2. Two Types of Flexibility:
a. Static flexibility refers to the ability to assume and maintain an
extended position at one end point in a joint’s range of motion.
9. Chapter 7 – The Joy of Fitness
b. Dynamic flexibility is the ability to move a joint quickly and fluidly
through its entire range of motion with little resistance.
B. The Benefits of Flexibility
1. Prevention of injuries
2. Relief of muscle strain
3. Relaxation
4. Relief of soreness after exercise
5. Improved posture
C. Stretching
1. Static stretching involves a gradual stretch held for a short time.
2. Passive stretching uses your own body, a partner, gravity or weight as an
external force or resistance to help your joints move through their range of
motion.
3. Active stretching involves stretching a muscle by contracting an opposing
muscle.
4. Dynamic stretching increases the range of motion around a joint or group
of joints by using active muscular effort, momentum, and speed.
5. Ballistic stretching is characterized by rapid bouncing movements.
D. Stretching and Warming Up
1. While stretching does not prevent injuries from jogging, cycling, or
swimming, it may benefit sports like soccer and football, which involve
bouncing and jumping.
2. For aerobic activities, one of the best times to stretch is after an aerobic
workout.
E. Stretching and Athletic Performance
1. In some cases, active stretching can impede rather than improve
performance in terms of muscle force and jumping height.
VIII. Mind–Body Approaches
A. Yoga
1. Yoga comes from the Sanskrit word meaning “union,” and consists of
various breathing and stretching exercises that unite all aspects of a
person.
2. Benefits include:
a. Improved flexibility
b. Protection of joints
c. Stronger, denser bones
d. Enhanced circulation
e. Lower blood pressure
f. Relief of stress-related symptoms and anxiety
10. Chapter 7 – The Joy of Fitness
g. Lower blood sugar
h. Reduced pain in people with back problems, arthritis, carpal tunnel
syndrome, fibromyalgia, and other chronic problems
i. Improved lung function in people with asthma
j. Less inflammation, fatigue, and depression in breast cancer survivors
B. Pilates
a. Pilates exercises improve flexibility and joint mobility and strengthen
the core by developing pelvic stability and abdominal control.
C. T’ai Chi
1. Ancient Chinese practice, designed to exercise body, mind, and spirit.
2. It gently works muscles, focuses concentration, and improves the flow of
“qi” (often spelled “chi”), the vital life energy that sustains health.
IX. Keeping Your Back Healthy
A. Low back pain causes more disability than nearly 300 other conditions
worldwide, according to new research, and nearly 1 in 10 people around the
globe suffers from an aching low back.
B. One of the most effective ways to prevent or recover from back problems is to
strengthen the core muscles.
X. Sports Nutrition
A. Introduction
1. Athletes in competitive sports may have increased energy requirements.
a. Athletes generally do not need more protein.
b. Complex carbohydrates are essential in an athlete’s diet.
c. Including the right types of fats in the daily diet can actually improve
athletic performance.
B. Water
1. We need more than any other nutrient.
2. The ACSM recommends fluid intake before, during, and after exercise to
regulate body temperature, and replace body fluids lost through sweating.
3. Hyponatremia or water intoxication is too much water during long
prolonged bouts of exercise.
C. Sports Drinks
1. Consuming a high-carbohydrate, high-caffeine sports drink 10 to 60
minutes before exercise may improve mental focus, alertness, anaerobic
performance, and endurance, but athletes should consider the effects on
their metabolic health.
2. Nonfat milk may be more effective than soy or sports drinks like Gatorade
at burning fat and building lean muscles mass.
11. Chapter 7 – The Joy of Fitness
D. Dietary Supplements
1. Vitamin and mineral supplements do not provide benefits to healthy,
well-nourished individuals.
2. Vitamin supplements marketed for athletes are poorly regulated, and
some may be adulterated with banned substances, such as ephedrine.
E. Energy Bars
1. Little scientific research has studied the benefits of the various types of
energy bars, including their effects on blood glucose levels and athletic
performance.
XI. Safe and Healthy Workouts
1. To prevent exercise-related problems before they happen, use common
sense and take appropriate precautions, including:
a. Get proper instruction.
b. Make sure you have good equipment and keep it in good condition.
c. Always warm up before and cool down after a workout.
d. Stay active throughout the week and do not overdo on weekends.
e. Use reasonable protective measures.
f. Go with a buddy.
g. Take each outing seriously.
h. Never combine alcohol or drugs with any sport.
B. Temperature
1. Heat Cramps
a. Heat cramps are caused by profuse sweating and the consequent loss
of electrolytes.
2. Heat Syndromes
a. More serious temperature-related conditions that include heat
exhaustion and heat stroke.
3. Heat exhaustion
a. Heat exhaustion is a mild form of heat-related illness that can be
caused by exercise or hot weather.
4. Heat Stroke
a. A heat stroke can occur when the body temperature rises to 106
degrees Fahrenheit or higher within 10 to 15 minutes.
5. Protecting Yourself from the Cold
a. Because frostnip is painless, you may not even be aware that it is
occurring.
b. Frostbite is more severe.
i. There are two types of frostbite, superficial and deep frostbite.
12. Chapter 7 – The Joy of Fitness
c. Hypothermia occurs when the body temperature falls below 95
degrees Fahrenheit and requires emergency medical attention.
C. Exercise Injuries
1. Types of injuries include:
a. Acute injuries—sprains, bruises, and pulled muscles—result from
sudden trauma, such as a fall or collision.
b. Overuse injuries result from overdoing a repetitive activity, such as
running.
2. PRICE
a. Protect the area with an elastic wrap, sling, splint, cane, crutches, or air
cast.
b. Rest to promote tissue healing.
c. Ice the area immediately.
d. Compress the area with an elastic bandage until swelling stops.
e. Elevate the area above your heart.
3. Overtraining
a. Signs of overdoing it include persistent muscle soreness, frequent
injuries, unintended weight loss, nervousness, and an inability to relax.
4. Exercise Addiction
a. Excessive exercise can become a form of addiction, and “exercise
dependence” is not uncommon among young men and women.
