How Much Exercise Is Enough?

For adults, most governmental agencies and credible professional or private organizations recommend at least 150 minutes of moderate intense activity or 75 minutes of vigorous intensity activity per week (an equivalent combination). Physical Activity Pyramid - A visual summary of minimal activity and exercise.

-FITT-ACSM's Training Guidelines for Cardiorespiratory Fitness

Frequency: Moderate: 3 Vigorous: 3 Intensity: Moderate: 64-75% of HRmax Vigorous: 76-95% of HRmax Time: Moderate: 30-60min (150 min/week) Vigorous: 20-60min (75min/week) Type (exercises): Rhythmic, aerobic, large muscle group activity

ACSM Flexibility Training Guidelines for Healthy Adults

Frequency: 2-3 days/week minimum; daily is most effective Intensity: Stretch to the point of feeling tightness or slight discomfort Time: 10 to 30 seconds per static stretch repetition; 2 to 4 repetitions of each stretching exercise; aim for 60 seconds total time per exercise Type: Static, dynamic, or PNF stretching of all major muscle groups

FITT Formula

Guideline to help plan personal exercise program Frequency: Number of times per week Intensity: How "hard" to exercise Time: Amount of time per exercise session Type: The Kind of Exercise performed -Determined by preferences, ability level, environment/accessibility, equipment, goals

Three Metabolic Systems Deliver Essential Energy: Step 1

Immediate energy system: Quick access to energy for "explosive" activities. Example: basketball jump shot

*Activity level

Inactivity can result in low flexibility levels (muscle and connective tissue shorten w/disuse)

How Can I Create My Own Cardiorespiratory Program?

Include Warm-Up and Cool-Down Phases --*Your CRF program sessions should consist of three key components. *1. Warm-Up Phase *2. Cardiorespiratory endurance conditioning set *3. Cool-down phase

Ballistic stretching

Involves bouncy, jerky movements, and high momentuym - Can be beneficial to athletes in specific ballistic sports

Dynamic stretching

Involves stretching through movement Mimics the motions of activities, but more slowly.

The Physical Activity Pyramid

Limit Sedentary Activities: Occassional: Watching TV, surfing the internet, etc. Work on Your Muscle Fitness and Flexibility: At least 2 days/week: Include all major muscle groups and joints. Exercise Your Heart and Lungs with Aerobic and/or Sports Activities: At least 3 days/week: Accumulate 150 minutes of moderate activity or 75 minutes of vigorous activity per week in 10 minute or longer sessions. Be Physically Active: Everyday: As much light/lifestyle activity as possible.

3. Involuntary Smooth Muscle

Lines internal organs and moves food through the stomach and intestines

Bursa

Percent Body Fat

Percentage of total weight that is fat tissue

2nd Primary Level of Physical Activity

Physical Activity: Any bodily movement produced by skeletal muscles resulting in expenditure energy. Typically grouped into 3 categories: light, moderate, vigorous.

1st Primary Level of Physical Activity

Physical Fitness: A set of attributes that relate to one's ability to perform moderate to vigorous levels of physical activity without undue fatigue.

4th Skill-Related Components of Physical Fitness

Power: ability to quickly produce force.

6th Factor of Designing a Fitness Program

Pregnancy- Don't start an intense exercise or weight-loss program but aim to keep moving throughout your pregnancy.

5th Principle of Fitness

Principle of Individuality: training results will vary from person to person due to genetic and individual differences.

2nd Principle of Fitness

Principle of Progression: to effectively and safely increase fitness, you need to apply an optimal overload level within a certain time period. -Follow the "10 percent rule": Increase your program frequency, intensity, or duration by no more than 10 percent per week.

6th Principle of Fitness

Principle of Rest and Recovery: body needs time to recover between training sessions. -schedule 1-3 days rest days per week for cardiorespiratory fitness training and every other day for weight training -may also alternate between hard workout days and easier workout days. -overtraining can result in fatigue and soreness.

4th Principle of Fitness

Principle of Reversibility: states that fitness gains are reversible AKA "Use it or lose it."

Body type

Typically affects flexibility only at extremes (excessive amounts of muscle or fat)

Estimating BMI

Underweight: <18.5 Normal: 18.5- 24.9 Overweight: 25-29.9 *Obese > 30

New ways to incorporate stretching

Yoga: Combines mental focus and physical effort Tai chi: Uses slow and smooth movements Pilates: Uses exercises and equipment to stretch and strengthen muscles Dance: Improves flexibility and overall fitness

Beginner exercisers may experience weight gain without

an increase in body fat due to an increase in muscle tissue.

Resistance training increases

Ballistic stretching may be appropriate

for some individuals in certain sports and recreational activities
