Skeletal system Flashcards
How does an increased bone strength occur and what effect does this have
Increased bone mineral density so they will be more resistant to forces of kicking, jumping or running
What is the first acute response of the skeletal system during exercise?
An increase in synovial fluid
This response helps lubricate joints and protect bones.
What does the skeletal system produce more of in synovial joints during exercise?
More synovial fluid
This production is to lubricate joints and protect bones.
Why is synovial fluid important for joints during exercise?
It lubricates joints and protects bones
Increased demands from exercise require more lubrication.
What happens to the viscosity of synovial fluid during increased physical activity?
It becomes less viscous
This change allows for better joint movement.
What effect does increased synovial fluid have on the range of movement at the joint?
It increases the range of movement
Enhanced lubrication leads to greater flexibility.
What does the release of synovial fluid from the synovial membrane provide to the articular cartilage?
Increased nutrients
Nutritional support is crucial for cartilage health.
What is an acute response to exercise related to bones?
Increased uptake of minerals within the bones
This response leads to stronger and denser bones.
How do bones become stronger and denser?
By regularly placing exercise demands upon them
Regular exercise leads to the absorption of minerals.
Which mineral is specifically mentioned as being absorbed to increase bone mineral density?
Calcium
Calcium is crucial for bone health and density.
What type of exercises are especially important for increasing bone mineral density?
Weight bearing exercises
These exercises apply stress and force to the bones.
What must bones be strong enough to cope with?
Increased stress and force applied to them
This is necessary when engaging in weight bearing exercises.
What is the first long-term effect of exercise?
Increased bone strength
Exercise increases bone mineral density, leading to stronger bones.
How does exercise affect bone strength?
It increases bone mineral density, resulting in stronger bones that are more resistant to forces in sports.
Examples of forces include kicking, jumping, or running.
What is the second long-term effect of exercise?
Increased ligament strength
Ligaments become more pliable over time due to stretching during exercise.
What happens to ligaments during a training program?
They stretch a little further than normal, becoming more pliable and increasing flexibility.
