A researcher records measurements from a participant before and after a 16-week resistance-training programme. The participant's height remains 2.00 m.
A body scan shows that some of the increase in the participant's mass is muscle.
BMI=mass in kg(height in m)2 \text{BMI} = \frac{\text{mass in kg}}{(\text{height in m})^2} BMI=(height in m)2mass in kg| Measurement | Before the programme | After the programme |
|---|---|---|
| mass in kg\mathrm{kg}kg | 96.0 | 104.0 |
| waist circumference in cm\mathrm{cm}cm | 92 | 88 |
| hip circumference in cm\mathrm{cm}cm | 100 | 104 |
Calculate the percentage change in the participant's BMI. Give your answer to one decimal place.
Calculate the change in the participant's waist:hip ratio. Give your answer to two decimal places and state whether it increased or decreased.
Explain what the changes in these measurements suggest about the participant's risk of developing type 2 diabetes.
