Weekly Quiz Questions Flashcards
What does Steven Blair (2009) warn will become the “biggest public health problem of the 21st century?
Physical inactivity
2 reasons why physical activity guidelines may be ineffective in increasing population physical activity:
People are told what to do, not how to do it
Lifestyle changes are not often sustained
What is the minimum amount of weekly physical activity for adults (18-64 years) recommended by the WHO to promote and maintain health?
150 minute of moderate intensity activity and muscle strengthening exercise twice a week
What is the alternative name for exercise science
Kinesiology
True or false: One implication of “specifity of adaptation” of strength and power, is that fitness assessments should be specific (similar) to fitness training. That is, the fitness test should require use of largely the same muscles and prefer alt pattern (s) of movement
True
Which method of measuring 2 compartment body mass (FM and FFM) is most reliable?
Dual energy X-ray absorptiometry
True or false: Fat is a valuble energy source in the body
True
The best form of exercise to burn fat energy stores is…
Prolonged, medium intensity
True or false: Fat secretes chemicals and metabolises sex hormones
True
BMI calculation
Body mass (kg)/Height(m2)
In the history of the WHO’s use of BMI, explain the upper limit of normal
The upper limit of normal has been shifted down from 27.8 to 25 kg/m2
The Achilles tendon inserting on the calcaneal tuberosity is an example of which kind of lever
Class 2 lever
Which class of lever has evolution typically favoured in relation to the mechanical configuration of our skeletal muscles
Class 3 lever
The 2 compartments of torque are:
Force and moment arm
As humans have long bones, there is a mechanical disadvantage of muscle attachments close to the fulcrum, but what advantages does adaptation this promote
Move with speed across a wide range of motion
Scott Kretchmar (2006) said in relation to quality physical education experiences: “if we aim for delight, we will surely get…..” what else?
Health
SportNZ’s nationwide approach to improve tamariki wellbeing is called:
Healthy active learning
Which is the best description of a threshold range that can be obtained within a graph depicting a dose-dependent response:
Where the best balance between benefit and safety in terms of further exposure is located
There are similarities and differences between physical activity (PA) and physical education (PE) in a school context. A key DIFFERENCE between the two is:
PA can be dine outside of school hours, whereas PE is done within school curriculum time
Sarcopenia is one of four main causes of reductions in muscle mass as we age. By what mechanism/s does sarcopenia occur?
a. Fast Type II muscle fibres converting to Type I fibres
b. Deposition of lipids within and between muscle fibres
c. Both (a) and (b)
Fast type II muscle fibres converting to type I fibres
Deposition of lipids within and between muscle fibres
Research indicates the most favoured places for physical activity in adolescents in Norway and in New Zealand are:
Open public, natural spaces
The biophillia hypothesis suggests:
Natural environments are associated with better health
Complete the following quote by W. Edwards Deming: “Without data, you’re just another person with an __________ “
Opinion
Which of the following statements aligns well with the philosophy and approach Michael Jacobs described in his presentation? (Select all that apply)
Leave no stone unturned: The more data you collect, the better!
Integrate don’t isolate, combine data with qualitative observations to provide a broad perspective about the athlete’s performance
Its not just about collecting data, it needs to be accurate and provide meaningful insight into quality of athlete’s movement

Which statement is true?
Humans are having no effect on the wider environment and are becoming more intrinsically able to tolerate such environments.
Humans are causing the natural environments to become more severe but becoming less intrinsically able to tolerate such environments.
It doesn’t matter what humans do to the natural environment because we are increasingly separated from it.
Humans are causing the natural environments to become more severe and also becoming more intrinsically able to tolerate such environments.
