Chapter 7-12 review Flashcards
Developing a personal fitness plan
- Set goals
- Select activities
- Set targets for each activity
- Set up a system of mini-goals and rewards
- Include lifestyle physical activity and strategies reduce sedentary time
- Develop tools monitoring progress
- Make a commitment
Why is it important to set goals?
having specific goals allow you to track your progress and enjoy the measurable changes brought about by your fitness program
interval training
- repeated bouts of intense exercise followed by rest
- e.g., on a running track, sprint the straightaways and walk the turns for three to five kilometres)
Arc Trainer
a weight-bearing, stationary exercise device that exercises the lower body muscles in a crescent-shaped pattern
Selecting Activities
- choose activities fun and interesting for you
- work at your current skill and fitness level
- work at the right time and convenience in your schedule
- friendly cost to your budget
- specify to your special health needs
Make a commitment
“sign an agreement”
be prepared to:
* start slowly and increase fitness gradually
* find an exercise buddy
* ask for support from others
* vary your activities
* cycle the duration and intensity of your workouts
* adapt to changing environments and schedules
* expect fluctuations and lapses
* choose other healthy lifestyle behaviours
Fitness Program for Children and Adolescents
- unconstructed play everyday
- dynamic activities during family outings (e.g., parking farther away from the store)
- for children younger than 12 , emphasize skill development and fitness rather than excellence in competitive sports
- gradually increase the complexity of the skill once the child has mastered the simpler skill
- make sure kids hydrate and dress properly for conditions of activity
Fitness Program for Pregnant Women
- see physician about modified activities for your particular pregnancy
- start exercising early pregnancy, combine aerobic exercise and resistance training
- warm-up and cool-down very every activity session
- 150 minutes of moderate-intensity 3x a week
- avoid exercising vigorously or till exhaustion, unless in a monitored environment
- non- or low-bearing exercises such as swimming or cycling over weight bearing exercises
- Include daily pelvic floor muscle training
- Avoid exercises that include physical contact with others or a loss of balance, avoid scuba diving and mountain climbing
- drink plenty of water and exercise in well-ventilated areas
Fitness Program for Older Adults
- same guidelines as young adults, but intensity on a 10-point scale rather than heart rate
- warm up and cool down slowly and carefully
- add bone and muscle strengthening activities involving major muscles groups 2x a week
- drink plenty of water, avoid excessively hot and cold environments
Exercise guidelines for people with arthritis
- begin early as possible in the course of the disease
- warm-up thoroughly to loosen stiff muscles and avoid injury
- avoid high impact activities that would damage arthritic joints
- strength and train the whole body, paying special attention to muscles that support and protect the affected joints
- preform flexibility exercises daily to maintain joint mobility
Exercise guidelines for people with Asthma
- exercise regularly since acute attacks are more likely to occur if you only exercise occasionally
- carry medication during workout and avoid working out alone
- warm up and cool down slowly to avoid acute attacks
- choose self-paced activities, and gradually increase for cardiorespiratory endurance activities
- educate yourself about situations that trigger an asthma attack
Exercise guidelines for people with Diabetes
- don’t begin an exercise until diabetes is under control and have discussed with physician
- don’t exercise alone and wear bracelet identification
- inject insulin in a muscle that will not be exercised and wait at least an hour before exercising to prevent abnormally rapid absorption of insulin
- check blood sugar before, during, and after exercise
- check skin for blisters and abrasions
- choose moderate-intensity activities for maximum benefit and minimum risk
Exercise guidelines for people with Heart Disease and Hypertension
- check with physician before training
- moderate intensity rather than high intensity, you should be able to talk while exercising
- keep heart rate below the level at which abnormalities appear on an exercise stress test
- warm up and cool down gradually, at least 10 minutes each
- monitor heart rate and stop if you experience dizziness or chest pain
- don’t hold breath when exercising, doing so can cause increase in blood pressure
- increase frequency, intensity, and time gradually
Exercise guidelines for people with Obesity
- choose low- to moderate-intensity activities for max benefit and min risk
- 60 minutes or more everyday (all at once or divided across the day) to lose weight or maintain weight loss
- non- or low-bearing exercises such as swimming, water exercises, cycling, or walking
- ease into exercise program and increase overload gradually
- include strength training in fitness program t build or maintain muscle mass
- include as much lifestyle physical activity in you daily routine
Exercise guidelines for people with Osteoporosis
- max intensity that causes no significant discomfort for cardiorespiratory endurance activities
- low-impact weight-bearing exercises to help safely maintain bone density
- avoid activity or movement that stresses the back and to reduce the risk of falls and fractures
- include weight training to improve strength and balance and avoid lifting heavy loads
- include muscle-strengthening and bone strengthening exercises 3x a week if they are safe for you (do not preform if you already have bone loss)
Nutrition
the science of food and how the body uses it in health and disease
Essential nutrients
substances the body must get from food because it cannot manufacture them at all or fast enough to meet its needs
* proteins
* fats
* carbohydrates
* vitamins
* minerals
* water
Examples of dirty dozen for 2022
- Strawberries
- Spinach
- Kale, collard and mustard greens
- Nectarines
- Apples
Examples Clean fifteen for 2022
- Avocados
- Sweet corn
- Pineapple
- Onions
- Papaya
Macronutrients
- essential nutrients required by the body in relatively large amounts
- include protein, fats, carbs, and water
Micronutrients
- Essential nutrients required by the body in minute amounts
- include vitamins and minerals
Digestion
the process of breaking down food in the gastrointestinal tract into the compounds the body can absorb
Kilocalorie
- a measure of energy content in food
- 1 kilocalorie = 1000 calories
Nutrient-Dense food
Foods that are high in essential nutrients but may be relatively low in calories
Energy supply of essential nutrients
Fat = 9 cal/g
Protein = 4 cal/g
Carbohydrates = 4 cal/g
Protein
- Form important parts of the body’s main structural components, muscles and bones
- Form important parts of blood, enzymes, call membranes, and some hormones
- Provide energy
Amino acids
the building blocks of proteins
how do you know if a protein in “complete” or “incomplete”?
- Considered “complete” if they supply all the essential amino acids in adequate amounts and “incomplete” if they do not
Recommended protain intake
Daily intake of protein for adults is 0.8 gram per kilogram of body weight
legumes
vegetables such as peas and bean that are high in fibre and are also important sources of protein
Fats
- The fats stored in the body represent usable energy, help insulate the body, and support and cushion organs
- Fats in the diet help the body absorb fat-soluble vitamins and add flavour and texture to foods
Essential fatty acids (EFAs)
Are used to make compounds that regulate body functions
Saturated
fatty acids found mostly in animal products and tropical oils; usually solid at room temperature
Unsaturated
fatty acids usually found in plant foods; usually liquid at room temperature
Hydrogenation
- a process by which hydrogens are added to unsaturated fats, increasing the degrees if saturation and turning liquids into solid fats.
- produces a mixture of saturated fatty acids and standard and trans forms of unsaturated fatty acids
Trans fatty acids (trans fat)
a type of unsaturated fatty acid produced during the process of hydrogenation; trans fats have an atypical shape that affects their chemical activity
low-density lipoprotein (LDL)
- blood fat that transports cholesterol to organs and tissues; excess amounts result in the accumulation of fatty deposits on artery walls
- contains a moderate amount of protein and a large amount of cholesterol; “bad” cholesterol
high-density lipoprotein (HDL)
- blood fat that helps transport cholesterol out of the arteries, thereby protecting against heart disease
- contains relatively little cholesterol that helps transport cholesterol out of the arteries; “good” cholesterol
Cholesterol
a waxy substance found in the blood and cells and needed for cell membranes vitamin D, and hormone synthesis
Carbohydrates
- an essential nutrient; sugars, starches, and dietary fibre are all carbs
- supply energy to the body cells
Simple Carbohydrates
Consist of the sugar molecules
Complex Carbohydrates
Include starches and most types of dietary fibre
Glucose
a simple sugar that is the body’s basic fuel
Glycogen
An animal starch stored in the liver and muscles
Whole grain
- The entire edible portion of a grain such as wheat, rice, or oats, including the germ, endosperm, and bran
*During milling or processing, parts if the grain are removed, often leaving just the endosperm
Refined carbs
Usually retain all the calories of their unrefined counterparts, but they tend to be much lower in fibre, vitamins, minerals, and other beneficial compounds
Glycemic index (GI)
a measure of how high and how fast a particular food raises blood glucose levels
Added sugars
High intake of added sugars is associated with health risks, including excess body weight and increased risk of type two diabetes
Recommended carbohydrates intake
45-65% of total daily calories, or about 225-325 grams of carbohydrate for someone who consumes 2,000 calories per day
Soluble (viscous) fiber
- fibre that dissolves in water or is broken down by bacteria in the large intestine
- Delay stomach emptying, slow the movement of glucose into the blood after eating, and reduce absorption of cholesterol
Insoluble fiber
- fibre that does not dissolve in water and is not broken down by bacteria in the large intestine
- Increase fecal bulk and helps prevent constipation, hemorrhoids, and other digestive disorders
Fibre intake in men and women
- 38 grams for adult men
- 25 grams for adult women
Dietary fibre
Non-digestible carbohydrates and lignin that are intact in plants
Functional fibre
Non-digestible carbohydrates either isolated from natural sources or synthesized; these may be added to foods and dietary supplements
Total fibre
the total amount of dietary fibre and functional fibre in the diet
Vitamins
- organic substances needed in small amounts to help promote and regulate chemical reactions and processes in the body
- Humans need 13 vitamins; of these four are fat-soluble and nine are water-soluble
- Help release the energy that is stared in carbohydrates proteins and fats
- Critical in the production of red blood cells and the maintenance of the nervous, skeletal, and immune system
- Some act as antioxidants, which help reserve healthy cells in the body
Antioxidants
a substance that protects against the breakdown of the body constitutes by free radicals; actions include binding oxygen, donating electrons to free radical, and repairing damage to molecules
Minerals
inorganic compounds needed in small amounts for regulations, growth, and maintenance of body tissues and functions
Anemia
a deficiency in the oxygen-carring material in the red blood cells
Osteoporosis
a conditions in which the bones become thin and brittle and break easily
Free radical
an electron-seeking compound that can react with fats, proteins, and DNA, damaging cell membranes and mutating genes in its search for electrons; produced through chemical reactions in the body and by exposure to environmental factors such as sunlight and tobacco smoke
Phytochemicals
- naturally occurring substances found in plant foods that may help prevent and treat chronic diseases such as heart disease and cancer
- phyto means plant
Cruciferous vegetables
- vegetables of the cabbage family, including cabbage, broccoli, brussels sprouts, kale, and cauliflower
- the flower petals of these plants form the shape of a cross, hence the name
Dietary Reference Intakes (DRIs)
an umbrella term for four types of nutrients standards:
* Adequate Intake (AI)
* Estimated Average Requirement (EAR)
* Recommended Dietary Allowance (RDA) set of levels of intake considered adequate to prevent nutrient deficiencies and reduce the risk of chronic disease
* Tolerable Upper Intake Level (UL) sets the max daly intake that is unlikely to cause health problems
Daily Values
a simplified version of the RDAs used on food labels; also included are values for nutrients with no established RDA
Canada’s deitary guidelines
general principles of good nutrition that are used for policy development, programs, and resources for Canadians
Health Equity
- the absence of unfair and avoidable differences in health within and between populations
- equity is not the same as equality
- to be treated equitably, the treatment may differ, but the goal is to achieve outcomes that are more equal
food insecurity
the state of being without reliable access to a sufficient quantity of affordable, nutritious food
Canada’s Food Guide
a food-group plan that provides practical advice to ensure a balanced intake of the essential nutrients
Causes of Foodbourne illness
most cases are caused by:
* pathogens
* disease-causing microorganisms that can contaminate food
* improper handling of food
