1. All of the following are true with regard to RSPs, except for:
A. They are attached to the sockets that encompass the residual limbs. B. They are in-series with the residual limbs and mimic the mechanical energy storage and return of tendons during ground contact. C. They generate mechanical power anew and return all of the stored elastic energy during running. D. All of the above are true with regard to RSPs.2. The data of this study suggest that as athletes exert greater forces on the ground and/or adjust the angle between the peak resultant ground reaction force and their RSP during stance, prosthetic stiffness is altered.
A. True B. False3. Which of the following was responsible for almost half of the dissipated energy?
A. Rubber soles B. The residual limb / socket interface C. RSP stiffness D. All of the above4. The height of RSPs need to be within a relatively narrow range for athletes with unilateral amputations.
A. True B. False5. Prosthetic stiffness adjustments would primarily be accomplished by changing:
A. Stiffness category B. Sagittal plane angle C. Both (A) and (B) D. None of the above6. Prosthetic stiffness varies with the magnitude of applied force.
A. True B. False7. Providing external lateral support:
A. Decreases step width variability. B. Decreases metabolic cost. C. Reduces the effort to maintain lateral balance. D. All of the above.8. All of the following are true with regard to ML foot placement, except for:
A. ML foot placement variability in sprinters with and without transtibial amputations generally increases with running speed up to maximum sprint speed. B. ML foot placement variability is symmetrical between the right and left legs of non-amputee sprinters and asymmetrically greater for the affected leg, with an RSP, compared to the unaffected leg of sprinters with a unilateral transtibial amputation. C. Increases in ML foot placement variability across speed differs between the affected and unaffected leg. D. All of the above are true with regard to ML foot placement.9. Which of the following tend to show a systematic tendency to place their feet closer to the body’s midline as they approach maximum speed?
A. Non-amputee sprinters B. Unilateral transtibial amputee sprinters and bilateral transtibial amputee sprinters C. Non-amputee sprinters and bilateral transtibial amputee sprinters D. None of the above10. Which of the following exhibited the greatest increases in ML foot placement variability with speed?
A. Unilateral transtibial amputee sprinters B. Bilateral transtibial amputee sprinters C. Non-amputee sprinters D. Both (A) and (B)11. In the present study, average velocity over 100 meters was greatest for:
A. Elite sprinters B. Sub-elite sprinters C. Non-elite sprinters D. Average velocity was equal for all sprinters12. The average step length was the longest for the non-elite sprinters, compared to the sub-elite and elite sprinters.
A. True B. False13. The differences in sprint performance between the elite, sub-elite, and non-elite sprinters is mainly due to the average step frequency rather than the average step length.
A. True B. False14. It has been demonstrated that during sprinting on a curved track, the inner leg consistently generates smaller peak forces than the outer leg, leading to a reduction of maximum performance of the entire locomotive system.
A. True B. False15. This study shows that athletes with left side amputations have slower race times than those with right side amputations.
A. True B. False16. The results of the current study suggest that amputation side is a factor that needs to be taken into consideration to ensure fairness in 200- and 400-m sprint events.
