Which of the following statements best explains the progression shown across the three femur images from left to right?
Using the clinical data in the table, what is a primary health benefit associated with regular physical activity?
| Activity Level | Mean Systolic BP (mmHg) | Mean Diastolic BP (mmHg) | Relative Risk of Stroke |
|---|
| Sedentary (0 min d⁻¹) | 142 | 94 | 1.00 |
| Moderate (30 min d⁻¹) | 130 | 85 | 0.74 |
| Vigorous (60 min d⁻¹) | 124 | 81 | 0.62 |
The image displays the WHO guidelines for physical activity and sedentary behavior in adults.
(a) the minimum amount of moderate-intensity aerobic physical activity recommended for adults per week.
(b) one strategy adults can use to reduce sedentary behaviour according to the image.
(c) the weekly aerobic activity recommendations for moderate- and vigorous-intensity physical activity shown in the image.
(d) why a gradual progression of exercise intensity is necessary when prescribing physical activity to previously sedentary individuals.
Which of the following is a well-established mental health benefit of regular physical activity?
Which consideration is most important when prescribing exercise during recovery from injury to minimise the risk of re-injury?
The bone becomes denser due to inactivity
The structure reflects increased calcium due to aging
The bone shows signs of osteoporosis due to physical inactivity
The images show normal adaptation to resistance training
Physical activity mainly reduces stroke risk and has little effect on blood pressure.
Increased activity levels support cardiovascular health by reducing the chronic pressure exerted on arterial walls.
Only vigorous exercise is effective at lowering systolic blood pressure below the hypertensive threshold of 140 mmHg.
Doubling the daily duration of exercise results in a linear, two-fold decrease in the relative risk of stroke.
Improved self-esteem
Reduced stress and improved mood
Improved cognitive function (e.g. attention)
Reduced symptoms of depression
Using pain alone to decide how quickly to increase training load
Tailoring intensity and volume to the individual and progressing gradually
Prioritising flexibility training over all other components of fitness
Returning to pre-injury training intensity as soon as symptoms reduce
