Gender differences are relatively small, characterized by
a slightly greater preference of males towards auditory learning and females towards kinesthetic learning
The task coaching method is characterized by
an open training environment, typically designed to allow for several different tasks to be undertaken with the athletes determining the most effective avenue to success
The cardiovascular system is comprised of all of the following EXCEPT:
lungs
Swimmers and athletes exercising in cold, rainy weather are at greater risk of experiencing
considerable body heat loss
What is the purpose of vasodilatation during soft tissue healing?
To remove infectious agents
When referring to the anatomy of the nervous system, the cell body of a neuron is also known as:
soma
High volume resistance exercise can cause cortisol to
exponentially increase during and after training
What is the rationale for recommending that athletes consume an increased protein intake to recover from intense endurance training?
For nitrogen balance due to increased protein oxidation
The mechanism of injury for a medial ankle sprain involves:
forceful and rapid eversion of the foot.
The gluteus maximus is the agonist (prime mover) for:
hip extension
Which core musculature system includes muscles that attach the spine and/or pelvis to the extremities that are primarily responsible for concentric force production and eccentric deceleration during dynamic activities?
Movement system
If the amortization phase is prolonged during a plyometric (reactive) training exercise, the amount of elastic potential energy:
decreases
60 seconds of rest will allow approximately:
85-90% recovery of ATP/CP.
What is the second phase of bone repair?
Callus formation
Which of the following sensory receptors are MOST sensitive to change in length of muscle and the rate of that change?
Muscle Spindles
In the free weight area of a weight room, a significant amount of space is needed around the benches for the following reasons EXCEPT:
designated areas for stretch mats, foam rollers, and other self-myofascial release modalities.
If the Squat Jump exercise is performed with a repeating tempo, in which level of the Optimum Performance Training Model would it belong?
Strength Level
All of the following are prerequisites for an athlete to possess prior to initiating plyometric exercises into an integrated training program EXCEPT:
proper levels of maximal strength.
What loads are typically recommended for athletes performing resisted speed drills for maximum carryover, because they allow for technique, joint velocities, and loads similar to that for competition?
10% body weight
According to research, what is the optimal stride length for maximal speed during sprinting?
2.3 to 2.5 times the athlete’s leg length
Optimal backside mechanics during sprinting include:
plantar flexion, knee extension, hip extension.
All of the following are probable causes of an athlete’s inability to produce adequate force during hip extension (ground push-off) while sprinting EXCEPT:
20 degrees of ankle dorsiflexion
Muscles that act in direct opposition to prime movers are known as:
antagonists.
Which exercise is considered a total-body stabilization exercise?
Ball Squat Curl to Overhead Press
Which exercise is considered a leg-strength exercise?
Lunge: Transverse Plane

VO2 Max.
Which phases of the OPT model are Olympic lifts MOST appropriate?
Phases 4 and 5
Which phase of the Snatch exercise occurs when the barbell is elevated from the knees to an area between the mid-thigh and the pubic bone depending on relative limb and torso segment lengths?
Shift (scoop)
Which acute variables BEST elicit the adaptation of maximal strength?
1-5 repetitions, 4-6 sets, 85-100% of one rep max (1RM)
Which of the following exercises is MOST appropriate for an athlete training in the Stabilization level (Phase 1) of the Optimum Performance Training model?
Ball Dumbbell Chest Press
According to the Optimum Performance Training model, how many repetitions are required during resistance training for a Phase 1 Stabilization Endurance Training workout for maximal adaptations?
12-20
Which phase of the Optimum Performance Training model is specific for the adaptation of maximal muscle growth, focusing on high levels of volume with minimal rest periods to force cellular changes that result in an overall increase in muscle size?
Hypertrophy Training
Which phase of the Optimum Performance Training model strictly focuses on high-velocity training for further increases in power by training with 30-45% of an athlete’s maximum strength and by accelerating through the entire range of motion?
Maximal Power Training
Common foot injury prevention and rehabilitation strategies include all of the following EXCEPT:
resisted dorsiflexion to lengthen and inhibit the anterior tibialis
The following are key roles of protein EXCEPT:
provides nine calories of energy per gram
Which hypothesis suggests that moderate levels of intensity are best served for motor skills?
Inverted-U hypothesis
