What is the primary mechanism by which adequate sleep reduces athletic injury risk?
Answer: Sleep facilitates hormonal release (GH, testosterone) and neural recovery, reducing tissue vulnerability
Adequate sleep promotes growth hormone secretion and neural recovery, maintaining tissue integrity and neuromuscular coordination needed for injury prevention.
Which mechanism explains why fatigue during a game's fourth quarter elevates ACL injury risk?
Answer: Fatigue degrades neuromuscular control, reducing protective muscle co-contraction around the knee
Muscular fatigue impairs neuromuscular control and joint stabilization, increasing ligament loading during cutting and landing tasks.
An athlete recovering from a grade II hamstring strain returns to sport. Which criterion is MOST important before full clearance?
Answer: Hamstring-to-quadriceps strength ratio restored and limb symmetry >90% on functional tests
Functional criteria including strength ratios and limb symmetry index are more predictive of safe return than pain-free passive range alone.
Which nutritional deficiency is most strongly linked to increased stress fracture risk in female athletes?
Answer: Calcium and vitamin D deficiency in the context of low energy availability
Low energy availability combined with calcium and vitamin D deficiency impairs bone remodeling, substantially increasing stress fracture risk (Female Athlete Triad).
Which ankle position creates the greatest risk for lateral ankle sprain during athletic cutting movements?
Answer: Plantarflexion with inversion
Plantarflexion with inversion places maximum tension on the lateral ankle ligaments (ATFL) in their most vulnerable position.
Single-leg squat assessments reveal that a female volleyball player's knee collapses medially. Which corrective exercise is MOST appropriate to target the primary deficit?
Answer: Clamshells and lateral band walks targeting hip abductors
Hip abductor strengthening exercises directly address the deficit causing medial knee collapse (dynamic valgus) during single-leg loading.
What does the term 'relative energy deficiency in sport' (RED-S) describe in the context of injury prevention?
Answer: Impaired physiological function from chronically low energy availability relative to training demands
RED-S encompasses the broad health and performance consequences of low energy availability, including increased injury risk through impaired bone health and tissue repair.
