“…Especially when fine motor control is involved, a necessary second step involves optimizing the execution of each element in the sequence (Penhune and Steele, 2012). Movement timing and movement velocity are two aspects of skilled motor performance that PP has been shown to optimize (e.g., Sanders, 1999; Khlifa et al, 2013). A surprisingly small number of studies has investigated whether this is the case for MP also, as most investigations have been concerned with practice outcome alone.…”

Mental practice (MP) has been shown to improve movement accuracy and velocity, but it is not known whether MP can also optimize movement timing. We addressed this question by studying two groups of expert pianists who performed challenging music sequences after either MP or physical practice (PP). Performance and motion-capture data were collected along with responses to imagery questionnaires. The results showed that MP produced performance improvements, although to a lower degree than PP did. MP and PP induced changes in both movement velocity and movement timing, promoting the emergence of movement anticipatory patterns. Furthermore, motor imagery was associated with greater changes in movement velocity, while auditory imagery was associated with greater movement anticipation. Data from a control group that was not allowed to practice confirmed that the changes in accuracy and kinematics were not due to mere repetition of the sequence during testing. This study provides the first evidence of an anticipatory control following MP and extends the present knowledge on the effectiveness of MP to a task of unparalleled motor complexity. The practical implications of MP in the motor domain are discussed.

“…These results indicated that the kinematics of the shoulder were associated with the accuracy of the free throw. Khlifa and colleagues 16) investigated the effects of a shoot training program with a reduced hoop diameter rim on the kinematics and performance of basketball free throws. The shoulder angle at ball release increased with shoot training, whereas the kinematics of the knee and ankle remained unchanged.…”

“…The free-throw shoot differs from other shots, such as 2-point, 3-point, and jumping shots, because players can take more time (five seconds), and can shoot with no pressure from opponent players. Many studies have reported factors affecting the accuracy of the free-throw, such as grip strength 1) , the pre-shot routine [2][3][4][5] , ball trajectory [6][7] , back spin 8) , quiet eye [9][10] , heart rate 11) , height of the release ratio, the center of gravity 12) , brain activity 13) , sleep time 14) , wrist-joint position sense 15) , kinematics of the shoulder angle 16) , elbow-wrist coupling 17) , and the kinematic chain 18) . However, these studies each focused on a singular factor at a time rather than multiple factors simultaneously in their effects on free-throw accuracy.…”

“…The third factor was kinematics, peak timing, and variability for the elbow, shoulder, hip, knee, and ankle joints during the free-throw motion. As mentioned above, previous studies mainly focused on kinematics of the upper limbs, including the wrist, elbow, and shoulder, in the free-throw [15][16][17] . In addition to this, the present study investigated the kinematics of the trunk and lower as well as upper limbs.…”

We investigated the relationship between basketball free-throw accuracy and anthropometry, physical fitness tests, and performance variables among 16 collegiate female basketball players. Each participant performed 20 basketball free throws. Anthropometric measures were height and weight; physical fitness tests were sit-and-reach, back strength, and grip strengths; other basketball performance variables were the phases of the pre-shoot routine: (a) time taken, (b) minimum angle when taking the ball back, (c) angle at ball release, (d) angular displacement during the forward arm swing, and (e) angular velocity at ball release on the elbow, shoulder, hip, knee, and ankle. We analyzed the correlation between free-throw accuracy and data on anthropometry and physical fitness, the time period and variability of the pre-shot routine, and kinematic data. There were negative correlations between free-throw accuracy and mean preshot time, and variability of the pre-shot time, indicating that participants with a shorter and less variable pre-shot time showed a higher free-throw accuracy. Angular displacement of the shoulder during the forward swing and angular velocity of the knee at ball release showed positive correlations with free-throw accuracy. There was also a negative correlation between freethrow accuracy and variability of angular displacement during the forward swing at the elbow, indicating that participants with smaller variability of angular displacement of the elbow showed higher free-throw accuracy. Some performance variables, including routine duration, angular displacement of the shoulder and elbow, and angular velocity of the knee, were related to freethrow accuracy.

“…The accuracy of a projectile landing on or near a target – also known as endpoint accuracy – can determine success in many sports . For example, in darts the impact location of the dart on the target determines the points that are scored, in hoop‐based sports such as netball and basketball the ball must fall through the hoop, and in goal‐based sports such as soccer and hockey the ball must land within the defined area captured by a net …”

Reductions in both temporal and spatial movement pattern complexity is associated with greater performance accuracy

et al. 2018

Push‐like movement patterns have often been associated with accuracy‐based skills because they are assumed to be less complex, however, a push‐like pattern may still exhibit significant complexity, and could require the same number and magnitude of joint rotations as a throw‐like pattern. The purpose of this study was to determine which movement pattern type is utilized, and the complexity with which they are executed. The badminton short serve was chosen for this study as it requires a high degree of accuracy with respect to trajectory of the shuttlecock during a complex skill. Three‐dimensional kinematics were obtained for eight members of the Australian National Doubles Badminton squad as they performed 40 serves each. Principal component analysis revealed that the most accurate servers used a push‐like movement pattern with elbow extension as the primary contributor and wrist adduction as the second largest contributor. They also used a more simplified push‐like movement pattern, restricting shoulder joint movement in all planes and elbow joint movement in the pronation/supination plane. These data support the hypothesis that reducing movement pattern complexity may allow for greater short serve accuracy, and that movement patterns may be more appropriately defined by their level of complexity of execution.
