Lesson Objectives
• Identify and describe the five areas of
health-related fitness.
• Understand how to improve each of the
five areas of health-related fitness.
• Examine the benefits of fitness on body
systems.
Elements of Fitness
• Cardiorespiratory endurance
• Muscular Strength
• Muscular Endurance
• Flexibility
• Body composition
Cardiorespiratory Endurance
• A measure of the heart’s ability to pump
oxygen-rich blood to the working muscles
during exercise.
– PE: Pacer or Mile Run/Walk
• Pulse Recovery Rate- number of times
your heart beats following exercise
• Resting Heart Rate- number of times your
heart beats in one minute at rest
Benefits of
Cardiorespiratory Endurance
• Lowers risk of heart disease
• Reduces risk of type II diabetes
• Helps lower blood pressure
• Increased bone density in weightbearing bones
• Increased longevity
Muscular Strength
• The maximal ability of a muscle to
generate force.
-PE: Pull Ups, Push Ups
(Less than 15)
Muscular Endurance
• The ability of a muscle to generate
force over and over again.
–PE: Hang, Curl Ups or Push Ups
(15+)
Benefits of Muscular Strength and
Endurance
• Lower risk of joint or muscle injuries
• Postpones the loss of muscle mass &
strength in older sedentary people
• Helps prevent osteoporosis by
increasing bone density
• Improvement in personal appearance
and self-esteem
• Increased energy levels & muscle size
Flexibility
The ability to move joints freely
through their full range of motion.
PE: “Sit & Reach”
Benefits of Flexibility:
• Increased joint mobility
• Efficient body movement
• Lower risk of injuries
• Reduced soreness after workout
Body Composition
The ratio of body fat to lean body tissue
(muscle, bone, water, etc.) in your body.
Benefits of Body Composition:
• Improvement in personal appearance and
self-esteem
• Reduced risk of several health problems
with low body fat % (cardiovascular
disease, obesity, high blood pressure, etc)
• Healthy range body fat % is 20-32%
according to ACSM
What is Exercise?
A purposeful physical activity that is
planned, structured, and repetitive, also
improves or maintains personal fitness.
Benefits of Exercise:
• Improves Body Systems:
– Immune (Heal Faster)
– Nervous (Reaction Time)
– Muscular & Skeletal (Stronger)
– Circulatory (Heart Pumps More Blood)
– Respiratory (Won’t “Lose” Your Breath)
You can choose from many different
physical activities and exercises to
improve your fitness level, but
most fall into one or two categories.
Types of Exercise
• Aerobic exercise: vigorous activity in
which the muscles use oxygen for energy
– Heart & Breathing Rate Increase
– Increase cardiorespiratory endurance
– Ex. Jogging, swimming, biking,
dancing
• Anaerobic exercise: intense short bursts
of activity in which the muscles work so
hard that they produce energy without
using oxygen.
- Ex. 100m dash, weight lifting
Types of Resistance Training
Isometric Exercise- muscle contraction with
little to no movement
Isotonic Exercise- muscle contracts with
movement
- Concentric-Muscle shortens
- Eccentric- Muscle length increases
Isotonic and Isometric
Contractions
