Opis:
In contrast to the abundance of motor skill acquisition and performance research, there is a paucity of work which addresses how athletes with an already learnt and well-established skill may go about making a subtle change, or refinement, to that skill. Accordingly, the purpose of this review paper is to provide a comprehensive overview of current understanding pertaining to such practice. Specifically, this review addresses deliberately initiated refinements to closed and self-paced skills (e.g., javelin throwing, golf swing and horizontal jumps). In doing so, focus is directed to three fundamental considerations within applied coaching practice and future research endeavours; the intended outcomes, process and evaluative measures of skill refinement. Conclusions suggest that skill refinement is not the same as skill acquisition or performing already learnt skills with high-levels of automaticity. Due to the complexity of challenge faced, refinements are best addressed as an interdisciplinary solution, with objective measures informing coach decision making.

Opis:
This study addressed several inconsistencies and omissions in golf putting research by testing the performance impact of target focused aiming. Participants were 22 high-level and experienced golfers, currently using ball focused aiming. Participants were allocated in a quasi-random fashion to ball or target focused aiming conditions and each performed 32 putts under competitive conditions on a natural putting green from a distance of 8 ft. Data were recorded as putts holed or missed and further categorised into putts missed long, short, left, right, short left, short right, long left and long right. There was no significant difference between conditions (p > 0.05) for any of the categories tested, despite participants’ prior extreme familiarity and expressed preference for the ball focused technique. These results notwithstanding, we discuss possible explanations for target focused benefits, including the role of vision during putting, the impact of intention during execution and possible expectancy effects. While these findings hold potential implications for golf coaching, more research is clearly required to further understand causative mechanisms and to clarify the existence and nature of advantage for one technique over the other. Based on this study, we recommend that high-level and experienced golfers might try target focused aiming as a ‘cost-free’ experiment.

Opis:
This study examined the validity of an inertial measurement unit system for measuring lower-limb joint kinematics during linear decelerations. A male team athlete (age 36 years, stature 1.75 m, mass 80.0 kg) performed multiple linear decelerations, following 20 m runs at 50%, 75% and 100% self-perceived effort. Inertial measurement unit sensors were strapped to lower-limb segments and retroreflective markers were adhered to the lower-limbs for 3D optical motion analysis. Ground contact time, foot to centre of mass displacement (foot-COM), peak and minimum angle, mean angular velocity and range of motion at the ankle, knee and hip during the contact phases of each deceleration were determined. Measures were valid if a very large correlation (r ≥ 0.7) and small bias (effect size < 0.6) were evident. Following 50% effort, ground contact time, foot-COM and most hip and knee kinematics were valid. Ground contact time, foot-COM and knee flexion velocity and range of motion were valid following 75% efforts. Ground contact time and knee flexion velocity were valid following 100% effort. Therefore, the inertial measurement unit system tested can be used to assess temporal-spatial parameters during a deceleration regardless of the preceding effort, and hip and knee kinematics following low intensity running.
