Which of the following statements is correct about the position of the foot and ankle complex during running movements?a. The fo
ot and ankle should be pointing straight ahead in a plantarflexed position when it hits the ground.b. The foot and ankle should be pointing straight ahead in a dorsiflexed position when it hits the ground.c. The foot and ankle should be pointing straight ahead in a dorsiflexed position in the air.d. The foot and ankle should be pointing straight ahead in a plantarflexed position in the air.
b. The foot and ankle should be pointing straight ahead in a dorsiflexed position when it hits the ground
Explanation:
Dorsiflexion is a movement in the ankle where the toes point in an upward direction allowing for correct foot strike if done properly at approx. 15 degrees. As you run, dorsiflexing your foot puts it in an ideal position to absorb the shock of the landing while simultaneously tensing your muscles to spring forward into the next stride which allows a reduced ground contact time per stride, allowing you to run faster and more efficiently.
If a runner has poor dorsiflexion they may experience a ‘loose’ or ‘floppy’ foot due to relaxation at the ankle joint which results in striking the ground through the toes which causes poor force distribution resulting in injuries such as shin splints and runner’s knee.
They originated in South America and spread throughout the world, but due to competition on other continents, the other marsupials died out, while the ones on Australia lived.
