4. The Effects of Exercise on the Skeletal System
 Improve Bone Density-
As the body ages, bone density naturally decreases.
In severe cases it leads to osteoporosis, resulting in
increased fractures and falls from weakness. Exercise
increases bone strength and mineral density.
Exercise helps to mitigate the process of bone
degeneration and causes remodeling of the bones, a
process which repairs small damages
and strengthens the bones to adapt to the demands
of exercise.

5.  Range of Movement in the Joints-
Joints connect bones in your body and
consist of tissues such as cartilage,
ligaments and meniscus. Regular exercise
also improves the health and mobility of
your joints while a sedentary lifestyle can
lead to joint degeneration and rigidity in the
joints

6.  Range of Movement in the Joints-
The muscles are an important component of
the musculoskeletal system. In addition to the
benefits to your bones and joints, exercise
increases your muscular strength, stamina and
flexibility. All of these components allow you to
perform tasks more easily and decrease your
risk of injury and falls. Strong muscles also
help to support and protect your joints,
decreasing the risk of injury, says Harvard
Health Publishing.

8. Short term effects of exercise on skeletal system
 On skeletal system would be increased amount of
synovial liquid, to keep joints healthy, stop
cartilage from drying out and keep cartilage
lubricated and nourished, the joints produce an oil-
like substance. Synovial fluid production increases
the range of movement available at the joints in
the short term.

9. Short term effects of exercise on skeletal system
 On the skeletal system would be increased bone
density, size and weight of bones. They become
stronger and flexible. More resistant to injuries and
faster recovery after injury. Increased bone density
can prevent a condition called osteoporosis, which
is the weakening of bone and an increased
likelihood of suffering fractures.

10. Effect of exercise on muscular system

11. Effect of exercise on muscular system
 Exercise involves a series of sustained muscle
contractions, of either long or short duration,
depending on the nature of the physical activity.
Effects of exercise on muscles can be considered
short-term both during and shortly after exercise
as well as long-term, lasting effects.

12.  Short-Term Effects
The effects of exercise on muscles varies with the
type and duration of the activity.Aerobic exercise is
typical of activities requiring endurance and
sustained muscle contractions. Such activities rely
mainly on Type I (slow-twitch muscles) which
sustain maximal contraction for extensive periods
of time. This use of slow-twitch muscles, and the
availability of oxygen, prevents the buildup of
lactic acid, and typically does not result in
substantial muscle fatigue in the short-term.
Sustained aerobic respiration tends to shift the
metabolic pathways of muscle to favor the use of
fat as the primary source of ATP, and glycogen is
generally avoided.

13. Anaerobic respiration, typical of sprinting and
weight lifting , prioritizes the use of Type II (fast-
twitch) muscles fibers for short, high-intensity
contractions. Muscles prioritize the use of readily-
available ATP, glucose and glycogen for these
contractions, which results in a build-up of lactic
acid. Though traditionally viewed as the cause of
muscle fatigue, recent research indicates ion
shortages, particularly of calcium, during an
aerobic exercise, causes such muscle fatigue.
However, lactic acid inhibits further ATP
production, indirectly causing fatigue.

14. Muscle soreness, once thought to be due to lactic
acid accumulation, has more recently been
attributed to small tearing of the muscles fibers
caused by eccentric contraction.

15.  Long-Term Effects
 Muscle hypertrophy, or the increase in muscle
mass due to exercise , particularly weight training,
is a noticeable long-term effect of exercise.
Exercise of specific muscles can often result in
hypertrophy in the opposite muscles as well, a
phenomenon known as cross education. Experts
and professionals differ widely on the best
approaches to specifically achieve muscle growth,
as opposed to focusing on gaining strength,
power, or endurance.

16. considered that consistent anaerobic strength
training will produce hypertrophy over the long
term, in addition to its effects on muscular strength
and endurance.
