An infant moves across the floor with their abdomen flat against the surface, pulling forward using bent arms and legs. How is this rudimentary movement pattern defined, and how does it differ from creeping?, Crawling; creeping involves elevating the abdomen completely off the ground while supported by straight arms and knees or feet., Creeping; crawling requires keeping the abdomen elevated off the floor while moving forward on hands and feet., Crawling; creeping is characterized by sliding backward with the torso completely elevated., Creeping; crawling relies strictly on a four-point balance where the belly does not touch the floor., An athlete is performing depth jump drills. Which technique adjustments ensure proper force absorption and injury prevention upon landing? Which of the following is NOT a proper technique?, Hinging at the hips and bending the knees to lower the center of gravity and absorb impact., Landing softly on the balls of the feet before rolling smoothly back toward the heels, Maintaining knee alignment over the toes to prevent inward collapse., Locking the knee joints completely upright upon impact to transfer ground reaction forces to the spine., What occurs during the amortization phase of a plyometric movement such as a box jump?, A brief isometric transition where the movement decelerates and switches from muscle lengthening to shortenin, A rapid concentric contraction where the muscle exerts maximum explosive force into takeoff., A rapid eccentric lengthening of muscles as the athlete lowers into the loading position., A sustained recovery period where the kinetic energy dissipates completely into heat., A parent is using the 'crawl cart' activity with an infant who heavily relies on leg strength but needs to build arm strength for crawling. How should the board setup be modified?, Place the infant on a longer board so only their hands can touch the floor to propel forward., Shorten the board so that only the infant's feet can reach the ground surface., Turn the infant onto their back (supine) so they push off nearby vertical surfaces with their feet., Tilt the board sideways to force the infant to use homolateral rolling movements., Which of the following is NOT a jump-landing technique training beneficial across all age groups and athletic levels?, It trains the lower body to absorb impact forces eccentrically, protecting joints and ligaments like the ACL., It develops movement control, balance, and coordination that transfer to running, cutting, and overall agility., It stimulates osteoblast activity through controlled weight-bearing vertical stress, supporting bone density., It bypasses the need for core stability during dynamic movements.
