Which of the following statement is correct in relation to high G manoeuvres? (select all that are correct, even if it is only one answer, even if it is only one answer):Each correct answer will score partial points, each incorrect answer will score an equivalent deductionGroup of answer choicesGreater muscle contraction and strength is required for movement in high G.Prolonged high G manoeuvres can cause reduced gas exchange.Untrained individuals cannot tolerant G force above 1g and will immediately black out.High G manoeuvres can cause black out due to the reduced blood flow to the brain.

Which of the following statement is correct in relation to negative G manoeuvres? (select all that are correct, even if it is only one answer):Each correct answer will score partial points, each incorrect answer will score an equivalent deductionGroup of answer choicesTolerance for negative G is much lower than for high G.Negative G causes fluid shift to the core of the body.Negative G can only be experience in parabolic flight.Prolonged or high negative G can rupture fine capillaries in the end and brain resulting in retinal damage, or haemorrhagic stroke.

Which of the following is a strategy that can be employed by people to compensate for the effect of high G force  (select all that are correct, even if it is only one answer): Each correct answer will score partial points, each incorrect answer will score an equivalent deductionGroup of answer choicesHold on tight to their surrounding equipment and hope it is over soon.The Anti-G-strain manoeuvre involving the isometric contraction of the muscles of the lower body including the legs and abdominals.Use a G-suit that inflates around the thorax and abdomen. This increase in pressure will help maintain blood flow to head.Hold their breath to maintain high CO2 as this helps regulate central cerebral blood flow to prevent black out.

Which of the following likely contributes to muscle loss during space flight? (select all that are correct, even if it is only one answer):Each correct answer will score partial points, each incorrect answer will score an equivalent deductionGroup of answer choicesDecrease in protein synthesis in microgravityDecrease in myoblast activity in microgravityDecrease reactive force resulting in lower contractile force required in microgravityDecrease in osteocyte activity in microgravity
