- Too Much Exercise
- Immunity
- Reduced natural killer cells
- Reduced phagocytes
- Reduced B cells
- Reduced T Helper cells
- Reduces amount of cytokines
- Cytokines are needed to activate lymphocytes
- Reduces number of antibodies produced
- Reduces amount of cytokines
- Inflammatory response in muscles due to damage to muscle fibres
- Reduced availability of non-specific immune response against upper respiratory tract infections
- Joints
- Treatment = RICE
- Articular cartilage wears away
- Bones grind together
- Inflammation
- Arthritis

- Inflammation
- Tenderness
- Ligament damage
- Immunity
- Medical Technology
- Keyhole Surgery
- Small incisions
- Cruciate Ligament
- Deep inside the knee joint
- Attached to end of femur and top of tibia
- Repeated damage can affect cartilage and shorten an athlete's career
- Fast recovery
- Little scarring
- Prostheses
- An artificial body part used by someone with a disability, to enable him/her to regain some degree of normal function or appearance
- Allows higher physical activity
- Allows higher performance for disabled athletes
- Replace damaged or diseased joints
- e.g. knee joint replacement
- Keyhole Surgery
- Moderate Exercise
- Increased number and activity of natural killer cells
- Found in blood and lymph
- Don't use specific antigen recognition
- Provide non specific immunity against cells invaded by viruses and cancerous cells
- Activated by cytokines and interferons
- Release perforin, making pores in the targeted cell membrane
- Induce apoptosis
- Increased vasodilation
- Lowered blood pressure
- Increased HDLs
- Reduced LDLs
- Maintaining a healthy body weight
- Improved blood glucose level regulation
- Increased bone density
- Decreased risk of osteoporosis
- Reduced risk of some cancers
- Improved mental well being
- Increased number and activity of natural killer cells
- Too Little Exercise
- Increased risk of..
- Stroke
- Coronary heart disease
- Cancer
- Obesity
