D.
Very young children’s throws tend to consist of primarily what type of action?(Aa)
Arm action
Which of the following is a characteristic of proficient overarm throwing?(Dtr, Lotua)
- differentiated trunk rotation
- lag of the upper arm behind rotation of the upper trunk
Which of the following is the most advanced developmental step in the backswing component of the overarm throw? (Cdb)
Circular downward backswing
Sex differences among children and adolescents have been documented in which body components for overarm throwing? (TrAa)
- Trunk rotation
- arm action
Sex differences among older adults in overarm throwing have been associated with which of the following? (Sacyae)
Both sex and childhood and young adult experiences
Action in which of the following body components is characteristic of early kicking? (La)
Leg action
Which of the following is a characteristic of early punting attempts? (Htkb, Ttbu, Kwtt)
- holding the knee bent as the ball is kicked
- tossing the ball up rather than just dropping it
- kicking with the toes
Which of the following is a characteristic of proficient sidearm striking? (Asith, Dtr, Aebc)
- a step into the hit toward the oncoming ball
- differentiated trunk rotation
- arm extension before contact
T/F: In changing from a throw for distance to a throw for accuracy, the most likely change observed would be a transition to lower steps in the developmental sequences.
True
T/F: One problem with using the throw for distance as a gauge of throwing development is that the score reflects body size and strength as well as skill
True
T/F: Research on the tennis serve in older adults demonstrates little change in the coordination of the serve during the older adult years.
True
T/F: Research on the golf swing demonstrates that most older adults are less accurate than young adult golfers.
False
T/F: In overarm striking, the upper arm (humerus) lads behind the trunk, but the racket precedes the forearm at ball contact.
False
T/F: Assuming the sequential movements are well timed, lag in the upper arm and forearm allows momentum to be transferred from proximal body parts to successively more distal body parts, increasing the speed of movement in the more distal body parts.
True
T/F: A long Contralateral step facilitates trunk rotation.
True
T/F: Recent research has shown that children can be at the most advanced levels of upper arm and forearm action before they routinely use trunk rotation.
False
T/F: One of the differences between development of throwing and development of overarm striking is the elbow action
True
T/F:Racket lag and trunk rotation less than 90 degrees are characteristics of proficient overarm striking.
False
In a proficient overarm throw at the time the shoulder rotates to the front-facing position, the upper arm (humerus) should be swinging forwards _______ (behind, even with, or ahead of) the shoulders.
Behind
Young children often use a _______ grip to hold the implement used in a striking task, thus ending to undercut the ball.
Power
In the development of throwing, trunk rotation in which the lower trunk and upper trunk rotate together, as a unit, is called ______ rotation.
Block
What individual structural constraints that change with aging could affect striking in older adults? How would these differ between older adults who remain active and those who become sedentary?
A loss of flexibility might limit range of motion; a loss of strength might limit speed or distance; a loss of balance might hamper the timing of sequential movements and the ability to apply force
There is a validated development sequence for punting but not for kicking. These skills are mechanically similar, however. Based on the developmental sequence for punting, hypothesize a developmental sequence for arm action in kicking.
no arm action to bilateral arm action to arm movement in opposition to the legs
