Anatomy and Physiology unit 1 BTEC SPORT level 3-Responses of the skeletal system to exercise

The video tutorial discusses the acute responses of the skeletal system to exercise, focusing on the increase of synovial fluid and mineral uptake in bones. These responses help protect bones and improve joint movement. The tutorial also provides exam tips on describing these effects and their benefits.

What is an acute response in the context of exercise and the skeletal system?

• A gradual increase in muscle mass

• A permanent change in bone structure

• An immediate change in the body

• A long-term adaptation of the body

What role does synovial fluid play in the joints during exercise?

• It increases bone density

• It acts as a lubricant to reduce friction

• It decreases muscle fatigue

• It enhances blood circulation

How does the viscosity of synovial fluid change during exercise?

• It solidifies

• It remains the same

• It becomes more viscous

• It becomes less viscous

What is one benefit of decreased viscosity in synovial fluid?

• Increased bone density

• Improved joint movement

• Enhanced muscle growth

• Reduced heart rate

Which mineral is primarily absorbed by bones during exercise to increase their strength?

• Calcium

• Magnesium

• Iron

• Potassium

Why is the increased uptake of minerals important for bones during exercise?

• To reduce joint lubrication

• To strengthen and densify bones

• To decrease bone density

• To enhance muscle flexibility

What type of exercise is mentioned as beneficial for mineral uptake in bones?

• Weight-bearing exercises

• Yoga

• Cycling

• Swimming
