LEARNING OBJECTIVES
1. Am I able to explain the effects a warm
up and cool down has on skeletal
muscle?
2. Can I explain different bone and muscle
conditions?
EFFECTS OF A WARM UP ON A
SKELETAL MUSCLE
• What effect does a warm up have
on a skeletal muscle?
EFFECTS OF A WARM UP ON A
SKELETAL MUSCLE
• An increase in core body temperature will
produce the following physiological effects
on skeletal muscle tissue:
– A reduction in muscle viscosity, leading to an
improvement in the efficiency of muscular
contraction
– A greater speed and force of contraction due
to a higher speed of nerve transmission
– An increased flexibility that reduces the risk
of injury due to increased extensibility of
tendons and ligaments
EFFECTS OF A COOL DOWN ON A
SKELETAL MUSCLE
• What effect does a cool down
have on a skeletal muscle?
EFFECTS OF A COOL DOWN ON A
SKELETAL MUSCLE
• An increase in the speed of removal of
lactic acid and CO2 that raise the acidity
levels of the muscle and affect pain
receptors due to oxygen rich blood
being flushed through the muscle
• A decrease in the risk of DOMS, which is
the muscular pain experienced 24-48
hours after intense exercise due to
microscopic tears in the muscle fibres
BONE/MUSCLE CONDITIONS
• You will be selected to use the computers to
investigate and feed back to the group about
the following bone conditions:
– Osteoporosis and how this affects physical activity
– Growth plate and how this affects physical activity
– Osteoarthritis and how this affects physical
activity
– Joint Stability and how this affects physical activity
– Posture and Alignment and how this affects
physical activity
TASK
• Copy and complete the following table in your
folders:

and Muscular Systems
• Make a presentation for your
selected Bone/Muscle
