Article
There is debate in the literature regarding how manipulating the focus of attention (FOA) influences ground reaction forces during the standing long jump (SLJ) and gaps in understanding as to which phases of the SLJ are affected (takeoff, flight, and landing) and whether FOA manipulation benefits remain when tasks are performed in fixed body postur...

Purpose: Medial tibial stress syndrome (MTSS) is one of the most common overuse injuries sustained by runners. Despite the prevalence of this injury, risk factors for developing MTSS remain unclear. The purpose of this study was to prospectively evaluate differences in passive range of motion, muscle strength, plantar pressure distributions, and r...

Movement screens are commonly used for assessing athletic readiness or injury potential. However, these screens fail to distinguish between movement dysfunction and movement skill. The purpose of this study was to compare performance on a common movement screen test, the overhead squat, when using no instructions (Baseline), instruction from a comm...
Article
The purpose of this study was to examine the effects of focus of attention cues on movement coordination and coordination variability in the lower extremity. Twenty participants performed the standing long jump under both internal and external focus of attention conditions. A modified vector coding technique was used to evaluate the influence of at...
Article
Recent motor control literature has demonstrated that using verbal instructions to direct a performer's attention externally (i.e. toward the movement outcome) enhances motor skill performance. The purpose of this study was to investigate how an athlete's focus of attention impacts kinematic performance of the snatch. Using a counterbalanced within...

Investigators have recently demonstrated that standing long jump performance is enhanced when participants focus their attention externally instead of to their leg action (9), but found no differences when examining peak force (15). The purpose of this study was to examine kinetic and kinematic properties associated with the standing long jump that...

An external focus of attention has been shown to improve balance measures during static postural tasks. The purpose of this study was to evaluate the effects of different attentional focus strategies in response to a perturbation while performing a dynamic balance task. Participants (n = 29) performed a dynamic balance task that consisted of steppi...

Background: In recent years, there has been a proliferation of technology and sport science utilized within an athlete's training, especially at the elite level. However, the sport science is a broad field, encompassing disciplines such as biomechanics, motor control and learning, exercise physiology, sports medicine, sport psychology to name a few...

Porter, JM, Wu, WFW, Crossley, RM, Knopp, SW, and Campbell, OC. Adopting an external focus of attention improves sprinting performance in low-skilled sprinters. J Strength Cond Res 29(4): 947-953, 2015-For more than 10 years, researchers have investigated how the focusing of conscious attention influences motor skill execution. This line of investi...
Article
It is known that proper proximal to distal sequencing of body rotations is important in the production of high club head velocities in the golf swing. Since these rotations originate at the pelvis, it is not clear how differences in pelvic kinematics are related to essential determinants of ball flight. One essential ball flight measure that has no...

For this study, we investigated the effects of self-controlled practice on learning multiple motor skills. Thirty participants were randomly assigned to self-control or yoked conditions. Participants learned a three-keystroke pattern with three different relative time structures. Those in the self-control group chose one of three relative time stru...
Article
Full-text available
Schmidt?s Schema Theory (1975) predicts that successful motor skill learning and performance are largely determined by the amount of movement variability the performer experiences during practice. This prediction has been consistently validated through a vast amount of research. Within a training environment, practice variability can be integrated...
Article
Traditionally, golf research and instruction have focused on the kinematics of the golf swing; while relatively little attention has been paid to the three-dimensional representing the change in these forces throughout the golf swing. If they are just represented by a few discreet variables, much of the variability is lost. Therefore, this study us...
Article
Full-text available
Numerous studies have demonstrated that using verbal instructions to direct a performers attention externally (i.e., toward the effect of the movement) significantly enhances motor skill performance. Limited research has also demonstrated that increasing the distance of an external focus relative to the body magnifies the effect of an external focu...

Article
Full-text available
Significant benefits in standing long jump performance have been demonstrated when subjects were provided verbal instructions that promoted an external focus of attention compared with an internal focus of attention, suggesting differences in ground reaction forces. The purpose of the present study was to evaluate peak force and jump performance be...
Article
Learning to perform a skilled behavior is affected by the context of the practice session and the frequency of augmented feedback. We studied the combined effect of these variables in the acquisition of a ballistic, bi-directional lever movement pattern involving four different target locations as measured by performance in practice, retention, and...
Article
Full-text available
I t is well documented that directing attention externally enhances motor skill learning and performance under controlled experimental conditions. What is not well understood is how verbal instructions (VI) and feedback provided by coaches in authentic environments influences athletes' focus of attention. Thus, the purpose of this study was to inve...

Several experiments have demonstrated that focusing a performer's attention externally (i.e., on the effects of a movement) rather than internally (i.e., on specific parts of the body) enhances performance when the task requires object manipulation (i.e., throwing a ball to a target). The purpose of this experiment was to investigate if whole-body...
