Q

What is a compact bone?

A

Compact bones are hard and heavy therefore a dense material. It is the hard outer structure of the skeleton. These are made up of units called lamellae which are sheets of collagen aligned in a parallel pattern which gives it its strength. Compact bones are supplied with oxygen and nutrients through a blood supply within the structure called Haversian canals/osteons.

Q

Explain how a lack of calcium could lead to osteoporosis

A

Calcium is involved in the skeletal system however in many other functions too such as muscle contractions, regulating fluid balances and transmission of nervous impulses. Bones act as calcium reservoir depending on the amount they can store and releases it. However, if there is not enough calcium in the body the bones will release it which can lead to osteoporosis.

Q

Explain osteoporosis

A

Bone remodelling is a balanced activity of osteoblasts and osteoclasts. Normally there would be a decrease in osteoblasts activity meaning there will be a drop in bone growth and also would lead to gradual loss of bone density.

Q

What are the causes of osteoporosis?

A
  1. Poor diet lacking minerals and vitamins

2. Overtraining

20
Q

What is a joint?

A

A joint is the location where two or more bones meet. The purpose of joints is to allow movement.

21
Q

What are the 3 types of joints and explain them?

A
  1. Fibrous - immovable and joined by fibrous tissue rich in collagen fibres.
  2. Cartilaginous - slightly moveable and joined by cartilage.
  3. Synovial - freely movable and the most common type of joint in the body.
22
Q

Explain the synovial joint structure

A

Synovial joints are freely moveable articulations. In these joints the bony surfaces are covered by articulate cartilage and connected by ligaments lined by synovial membrane. The bones of the synovial joints are covered in a layer of hyaline cartilage at the epiphysis with a smooth slippery surface to allow smooth joint movement, reduce friction and absorb shock during movement.

23
Q

What are the 4 characteristics of synovial joints?

A
  1. Ends of bones are covered by hyaline cartilage
  2. Enclosed by ligaments for stability
  3. Surrounded by fibrous capsule
  4. Capsules lined by synovial membrane containing synovial fluid for lubrication
24
Q

What are the 6 synovial joint types?

A
  1. Gliding/Plane
  2. Hinge
  3. Ball and socket
  4. Saddle
  5. Condyloid/ellipsoid
  6. Pivot
25
Q

Explain vitamins

A

We get vitamins from plant foods or animals that have eaten plant foods. We also synthesise vitamins in the digestive tract. Vitamins are organic compounds that can be classified as water soluble and fat soluble.

26
Q

Describe water soluble vitamins

A

Vitamins B and C are water soluble which means that you need to consume them daily. This is because the body is unable to store water soluble vitamins in a meaningful amount so you need to consume them regularly. Any excess will be eliminated through urine. This is why an excess of vitamin C can make the urine look a greeny colour. Too much vitamin C can also increase the acidity levels in the digestive and urine systems which could lead to an upset stomach. Biotin is also produced by a bacteria in the digestive tract.

27
Q

Describe fat soluble vitamins

A

Vitamin A, D, E and K are fat soluble vitamins meaning they are transported and utilised in the presence of fat. They don’t need to be consumed as regularly this is because the body is able to store them. A diet lacking fat could lead to deficiency of these vitamins. The production of steroid hormones such as testosterone and oestrogen require plentiful amount of vitamin A.

28
Q

Explain minerals

A

Minerals are organic compounds that are present in the earth which food grows in. The plants absorb the minerals and we eat them. Minerals roughly make up about 4% of overall body weight and just like vitamins they are essential for health and well-being. Minerals can be divided up into two; macro and trace minerals.

29
Q

What functions do minerals aid in the body?

A
  1. Muscle contractions
  2. Regulate fluid balance
  3. Bone formation
  4. Nerve function
30

  2. Skill related fitness
  3. Medical fitness
  4. Nutritional fitness
  5. Mental/emotional fitness
  6. Social fitness
31
Q

What does the physical fitness consists of? Explain each

A

Muscular Strength - strength is the ability to generate force against a resistance. It helps with everyday tasks and also has a positive influence on bone mass.

Muscular Endurance - this is the ability of the muscles to generate lower levels of force for an extended period of time. It’ll help with daily tasks as well as good posture.

Cardiovascular Fitness - this is the ability of the heart and lungs to take in, transport and utilise oxygen in the body. CV fitness can be improved by doing low to moderate intensity exercises for an extended period of time e.g. swimming or jogging.

Flexibility/Mobility - flexibility is the ability to move the joint through a wide but healthy range of motion. The health and fluidity of movement of a joint is mobility. They’re both essential for musculoskeletal function and a good posture.

Body Composition - this is the relationship between fat and lean body weight. It is influenced by diet, exercise and general lifestyle.

32
Q

What does the skill related fitness consists of? Explain each

A

Reaction time - is the ability to react quickly to a stimulus. Reaction time depends on the sensory and motor nerves working together.

Power - is the ability to generate force rapidly. Strength has no speed component e.g. doing a heavy eccentric squat. Whereas power is generating force quickly e.g. a vertical jump.

Speed - is about the quickness of movement wether it be running or throwing a jab in boxing etc. Speed can be developed through training but limited due to dominant muscle fibre types.

Agility - is the ability to move quickly and change directions quickly and at high speeds. Generally athletic.

Coordination - is the ability to move multiple limbs harmoniously and accurately.

Balance - is the ability to keep the centre of mass over the base of support e.g. standing on one leg or doing a handstand.

Proprioception - the ability to sense where the limbs are placed just be feel. E.g. maintaining a neutral spine without seeing the back.
