7. INTRODUCTION:
The biggest obstacle to a regular physical
activity habit that most of us are aware of is a
lack of time. Even though we have the best of
intentions to be more active, work, family
responsibilities, and other aspects of daily life
frequently get in the way. Additional impediments
abound and depend on the individual and their
situation in life.
8. With technological advancements and conveniences, people's lives have become increasingly simpler
and less challenging in many respects. In fact , people have several personal reasons or excuses for
being inactive.
1. Personal Barriers
9. insufficient time to exercise
inconvenience of exercise
lack of self-motivation
non-enjoyment of exercise
boredom with exercise
lack of confidence in their ability to be physically
active (low self-efficacy)
Personal Barriers
10. fear of being injured or having been injured recently
lack of self-management skills, such as the ability to set personal goals, monitor
progress, or reward progress toward such goals
lack of encouragement, support, or companionship from family and friends
non-availability of parks, sidewalks, bicycle trails, or safe and pleasant walking
paths close to home or the workplace
Personal Barriers
11. The climate in which we work has a significant effect on our degree of physical activity. There are
several variables in our world that impact us. The obvious considerations include the accessibility of
walking trails, bike paths and recreation facilities. Factors such as traffic, provision of public
transport, crime and pollution can also have an impact.
2. Environmental Barriers
12. Schedule activities into your day and use an exercise log so you can
see how little time it takes.
Build activities into everyday tasks no matter where you are: Bike to
work. Use the stairs. Take walk breaks at work. Garden. Park your car
farther away from stores.
Find an activity you enjoy that works for your schedule
13. ACTIVITY 1: Fitness Reflection
In one (1) whole paper, answer the following questions about
Physical Fitness
1.What is the importance of Physical fitness?
2.In your physical fitness assessment, describe the result and
the effect on yourself.
3.As a student, how will you improve your physical fitness?
15. Enumerate and identify the three energy
systems
At the end of the lesson, the students will be able to
Explain the variations between the three
energy systems and how they operate
Perform physical activity using three energy
systems
17. The Anaerobic A-lactic System (AA), also called the
creatine phosphate system, or the ATP-CP system,
deals primarily with the quick supply of ATP for fast
and powerful movements. Because it relies primarily
on the little ATP that is already present in the muscles,
supplies run out fairly quickly, and fast and powerful
movement drops off after just a few seconds
Most athletes competing in sports events need a short period of acceleration.
Athletic events such as shooting, weightlifting and 100-metre sprinting are
examples of physical activities that use the ATP-CP energy system. However,
the ATP-CP system will not supply ATP again until the muscles have rested
and are able to regenerate.
18. As intensity increases, it becomes increasingly difficult for the body to provide
enough oxygen to fuel aerobic pathways. The short term, or anaerobic lactic
(without oxygen, with lactic acid) system begins to contribute more energy to
fuel the muscle. Fuel for this system comes from glucose in the blood and
stored glycogen in the muscle. Along with energy (ATP), lactic acid is produced
as a byproduct of this system. As exercise intensity increases, so does the
accumulation of lactic acid in the blood and muscles.
Anaerobic Lactic is also known as the glycol energy system, an energy system
that provides energy for medium to high physical activity. Such high-intensity
tasks typically last from ten seconds to two minutes.
19. The aerobic energy system provides energy for low-intensity physical activity
that lasts from two minutes to a few hours. Aerobic energy system, compared
to ATP-CP and glycolytic energy systems, requires much longer oxygen in
muscles when performing physical activities such as long-distance swimming
and sports.
Aerobic energy system continuously provides ATP energy to muscles as long
as oxygen is available to muscles in the body. By comparison to the anaerobic
lactic system, the aerobic energy system does not contain lactic acid because
oxygen is available to the muscles.

systems.
