Acute and Long-Term Effects of Attentional Focus Strategies on Muscular Strength: A Meta-Analysis.

This review aimed to perform a meta-analysis examining the following: (a) acute effects of adopting an internal focus vs. external focus of attention on muscular strength; and (b) long-term effects of adopting an internal focus vs. external focus of attention during resistance training on gains in muscular strength. We searched through five databases to find eligible studies. Random-effects meta-analyses of standardized mean differences were conducted to analyze the data. Ten studies were included. In the meta-analysis for the acute effects, there was a significant positive effect of external focus on muscular strength (standardized mean difference: 0.34; 95% confidence interval: 0.22, 0.46). In the meta-analysis for the long-term effects, there was no significant difference between training with an internal focus and external focus on muscular strength gains (standardized mean difference: 0.32; 95% confidence interval: –0.08, 0.73). In the subgroup analysis for lower-body exercises, we found a significant positive effect of training with an external focus on muscular strength gains (standardized mean difference: 0.47; 95% confidence interval: 0.07, 0.87). In summary, our findings indicate an acute increase in muscular strength when utilizing an external focus of attention. When applied over the long-term, using an external focus of attention may also enhance resistance training-induced gains in lower-body muscular strength.

Translating Thoughts Into Action: Optimizing Motor Performance and Learning Through Brief Motivational and Attentional Influences

Skilled motor performance is essential in sports, the performing arts, various occupations, and many daily activities. Scientists and practitioners alike are therefore interested in understanding the conditions that influence the performance and learning of movement skills, and how they can be utilized to optimize training. In OPTIMAL theory, three motivational and attentional factors are key: enhanced expectancies for future performance, the performer’s autonomy, and an external focus of attention. We review recent evidence suggesting that each factor contributes independently to strengthen the coupling of goals to actions. This work has implications ranging from fostering more effective skill development in novice learners, to increasing the efficiency of athletes’ and musicians’ performance, and to facilitating the success of patients in regaining functional capabilities.

Individual Differences in Sequential Movement Coordination in Hip-Hop Dance: Capturing Joint Articulation in Practicing the Wave.

The current study highlights individual differences in the joint articulation strategies used by novices practicing a hip-hop dance movement, the wave. Twelve young adults, all naive regarding hip-hop dance performance, practized the wave in 120 trials separated into four blocks with the order of internal or external attentional focus counterbalanced across subjects. Various kinematic analyses were analyzed to capture performance success while exploiting the observed individual differences in order to establish the reliability of the proposed performance indicators. An external focus of attention marginally facilitated the smooth transfer of a wave motion across neighboring limb segments as characterized by a constant propagation speed combined with large wave amplitudes. Systematic correlations between the success indicators were found, exemplifying the various degrees of joint articulation that novices prove capable of during an initial practicing session to try and perform a novel complex motor task.

External and global internal focus of attention on whole-body similarly increases the vertical jump performance: a randomised, controlled and crossover study

ABSTRACT This study aimed to compare the effects of three different foci of attention (external focus, global internal and specific internal focus) on vertical jump performance. Thirty-two recreationally active males participated in this study and performed the jumps at three different foci of attention conditions. The specific internal focus was based on the knee extension and the global internal focus was on whole-body extension. The external focus was conducted using an implement (plastic ball) attached to the laboratory ceiling. The analysis of variance for repeated measures with Bonferroni post hoc test was used to compare the performance variables among the conditions with the significance level set at p < 0.05. The main results demonstrated that the jump height was higher in the external focus condition compared to the control (p = 0.003) and the specific internal focus (p < 0.001); jump height was also higher in the global internal focus compared to specific internal focus (p = 0.012). The peak power and velocity were higher in the external compared to specific internal focus (p = 0.040 and 0.006, respectively). We concluded that external focus showed better performance for the peak power and velocity, while global internal focus showed higher performance for jump height compared to specific internal focus and a similar performance to the external focus.

Rhythmic and non-rhythmic auditory precues: Multiple mechanisms mediating movement performance

Rhythmic auditory stimuli presented before a goal-directed movement have been found to improve temporal and spatial movement outcomes. However, little is known about the mechanisms mediating these benefits. The present experiment used three types of auditory stimuli to probe how improved scaling of movement parameters, temporal preparation and an external focus of attention may contribute to changes in movement performance. Three types of auditory stimuli were presented for 1200ms before movement initiation; three metronome beats (RAS), a tone that stayed the same (tone-same), a tone that increased in pitch (tone-change) and a no sound control, were presented with and without visual feedback for a total of eight experimental conditions. The sound was presented before a visual go-signal, and participants were instructed to reach quickly and accurately to one of two targets randomly identified in left and right hemispace. Twenty-two young adults completed 24 trials per blocked condition in a counterbalanced order. Movements were captured with an Optotrak 3D Investigator, and a 4(sound) by 2(vision) repeated measures ANOVA was used to analyze dependant variables. All auditory conditions had shorter reaction times than no sound. Tone-same and tone-change conditions had shorter movement times and higher peak velocities, with no change in trajectory variability or endpoint error. Therefore, rhythmic and non-rhythmic auditory stimuli impacted movement performance differently. Based on the pattern of results we propose multiple mechanisms impact movement planning processes when rhythmic auditory stimuli are present.

Effect of Neutral, Internal, and External Focus on Drop Jump Performance: Is Drop Jump Performance Affected by Plyometric Training Experience?

Furuhashi, Y, Hioki, Y, Yoshimoto, S, and Hayashi, R. The effect of neutral, internal, and external focus on drop jump performance: is drop jump performance affected by plyometric training experience? J Strength Cond XX(X): 000-000, 2021-Providing an external focus of attention through verbal instructions can improve the drop jump (DJ) performance, which differs based on the skill level of athletes. The purpose of this study was to assess the effect of change of focus of attention on the performance of DJs in experienced and inexperienced athletes. Thirty-eight male collegiate athletes divided into the experienced group (E group: age, 21.5 ± 1.4 years; height, 173.4 ± 5.7 cm; and body mass, 65.7 ± 6.2 kg) and the inexperienced group (I group: age, 21.9 ± 1.5 years; height, 172.8 ± 5.1 cm; and body mass, 68.7 ± 5.5 kg) performed 2 trials of DJs after listening to instructions designed to evoke a neutral, internal, or external focus of attention. Contact time (CT), jump height (JH), reactive strength index (RSI), and leg-spring stiffness (k vert ) were recorded during DJ and compared between the 2 groups using a repeated-measures analysis of variance. In the E group, the neutral condition was associated with a significantly higher RSI, JH, and k vert than the internal and external conditions ( p < 0.05). In the I group, the external condition was associated with significantly higher RSI and k vert and shorter CT than other conditions ( p < 0.05). Therefore, this suggests that attentional focus strategies need to be selected depending on DJ experience: A neutral focus may be preferable for athletes experienced in DJs, whereas an external focus may be more suitable for athletes with lesser DJ experience.

External Focus of Attention Influences Cortical Activity Associated With Single Limb Balance Performance.

External focus (EF) of attention leads to improved balance performance. Consideration of the neuromodulatory effects of EF may inform its clinical utility in addressing neuroplastic impairments after musculoskeletal injuries. This study aimed to determine whether electrocortical activity and balance performance changed with attentional foci that prioritized differing sensory feedback and whether changes in electrocortical activity and balance were associated. Individuals who were healthy (n = 15) performed a single-limb balance task under 3 conditions: internal focus (IF), somatosensory focus (EF with a baton [EF-baton]), and visual focus (EF with a laser [EF-laser]). Electrocortical activity and postural sway were recorded concurrently using electroencephalography and a triaxial force plate. Electroencephalographic signals were decomposed, localized, and clustered to generate power spectral density in θ and α-2 frequency bands. Postural sway signals were analyzed with center-of-pressure sway metrics (eg, area, distance, velocity) and knee angle. The relationship between percent change in clustered brain activity and task performance metrics was assessed. Both EF conditions resulted in increased cortical activity and improved balance performance compared with IF. EF-laser had the largest effect, demonstrating increased frontal θ power (d = 0.64), decreased central θ power (d = -0.30), and decreased bilateral motor, bilateral parietal, and occipital α-2 power (d = -1.38 to -4.27) as well as a shorter path distance (d = -0.94) and a deeper (d=0.70) and less variable (d = -1.15) knee angle than IF. Weak to moderate associations exist between increases in cortical activity and improved balance performance (ρ = 0.405-0.584). EF resulted in increased cortical activity associated with cognitive, motor, somatosensory, and visual processing. EF-laser, which prioritized visual feedback, had the largest and broadest effects. Changes in cortical activity resulting from EF were independently associated with improved balance performance. This study demonstrates that goal-oriented attention results in functional increases in brain activity compared with internally directed self-focus. These results suggest EF may target neurophysiologic impairments and improve balance in clinical populations.

The role of attainability and external focus of attention on standing long jump performance

BACKGROUND: External focus of attention (FOA) promotes enhanced performance and learning in comparison to internal FOA; however, several dimensions associated with external FOA appear to have varying influence on motor skill performance. AIM: The purpose of this study was to investigate whether an attainability aspect of external FOA elicits enhanced standing long jump performance. METHOD: Fifteen healthy males performed standing long jumps in the following conditions: without a visual target (Tno), target placed at maximum distance (Tmax), and a target placed 10% beyond maximum distance (Tmax+10). Jump distances were measured, and kinetic data were recorded using a force platform. RESULTS: One-way ANOVA showed significantly greater jump distances for Tmax+10 compared to Tno and Tmax (p &lt; 0.01). Additionally, the impulse of the ground reaction force (GRFimpulse) in the anterior-posterior direction was significantly greater for Tmax and Tmax+10 compared to Tno (p &lt; 0.05). CONCLUSION: Thus, an external FOA tailored to individual ability benefits standing long jump performance. Overall, the findings support the approach of adopting an external FOA with an emphasis on targets that are specific to the individual and based on attainability.

Superiority of external attentional focus for motor performance and learning: Systematic reviews and meta-analyses.

Considerable literature on the role of attentional focus in motor performance and learning has accumulated for over two decades. We report the results of comprehensive meta-analyses that address the impact of an external focus (EF, on intended movement effects) versus internal focus (IF, on movements of body parts) of attention on the performance and learning of motor skills. Values of effect sizes (ES) from 73 studies with 1,824 participants and 40 studies with 1,274 participants were used for examining the effects of EF versus IF on behavioral outcomes of motor performance and learning (separately for retention and transfer phases) respectively. The EF condition was more effective than the IF condition for performance, Hedges' g value = 0.264 (95% CI [0.217, 0.310]), retention learning, Hedges' g value = 0.583 (95% CI [0.425, 0.741]), and transfer learning, Hedges' g value = 0.584 (95% CI [0.325, 0.842]). Multivariable metaregression analyses on behavioral measures further indicated that neither age group, health status, or skill level, nor their two-way interactions, moderated the ES differences between EF and IF in performance, retention, and transfer models (all p > .100). A secondary analysis on 12 studies with 216 participants that examined the effects of EF versus IF on electromyographic outcomes of motor performance also indicated that EF was associated with more efficient neuromuscular processing, Hedges' g value = 0.833 (95% CI [0.453, 1.213]). From nine studies with 272 participants, performance measured by behavioral outcomes was found to be more effective when a more distal, rather than proximal, EF was used, Hedges' g value = 0.224 (95% CI [0.019, 0.429]). Overall, the meta-analytic results are consistent with prior narrative reviews and indicate that an external focus is superior to an internal focus whether considering tests of motor performance or learning, and regardless of age, health condition, and level of skill expertise.

EXTERNAL FOCUS OF ATTENTION ENHANCES PRECISION IN RECREATIONAL ARCHERS

The studies confirm that instructions and feedback that induce external focus of attention (oriented on movement outcome) result with greater efficiency in motor performance and learning regarding internal focus of attention (oriented on bodily dimensions). Advantages and differences between external and internal focus of attention have been proved also in different levels of sport and recreational expertise. In this study, 10 recreational archers were tested in three different conditions: C1 - freely oriented focus of attention, C2 – internally oriented focus of attention, and C3 – externally oriented focus of attention. The subjects first undertook the C1 condition, and afterwards the next two conditions were randomly decided. According to the hypothesis, the main goal was to investigate the effect of external and internal focus of attention on precision of the shots. According to the results, in externally focused condition, recreational archers had better results than in other conditions with higher number of 9 points and lesser number of misses. Based on findings from this paper, adopting an external focus of attention should be beneficial for the shot precision, self-fulfillment and feelings of accomplishment in recreational archers.

The Effects of Biofeedback on Performance and Technique of the Boxing Jab.

A growing body of research has addressed the application of movement-based biofeedback techniques for improving sports performers’ gross motor skills. Unlike in previous research, we aimed in this study to quantify the effects of this “external” biofeedback on selected performance and technique variables for the boxing jab among both novices and experts. The technical setup included two inertial measurement units linked wirelessly to a video game system with audio output. The units were configured to provide auditory external biofeedback, based on the peak acceleration of the bag (i.e., biofeedback with an external attentional focus). Sixteen participants (8 novices and 8 experts) performed boxing jabs against the bag in blocked phases of biofeedback. When compared to baseline, the acute effects of externally focused biofeedback on peak bag acceleration were possibly positive in both retention phases for novices (d = 0.29; d = 0.41) and likely positive for experts (d = 0.41; d = 0.30), respectively. The experts’ performance improvements were accompanied by substantive increases in trunk rotation, though this was not true for the novices. Thus, technique improvements can be promoted indirectly via externally focused biofeedback, but only when these actions are within the performers’ motor repertoire. Overall, biofeedback via inertial sensors appears to be a potent technique for modifying human movement patterns in both experts and novices. This low-cost technology could be used to support training across sports, rehabilitation and human-computer interactions.

Putting Attention on the Spot in Coaching: Shifting to an External Focus of Attention With Imagery Techniques to Improve Basketball Free-Throw Shooting Performance

Attentional focus is an area that has garnered considerable attention in the sport psychology and motor performance literature. This is unsurprising given that attentional focus has been directly linked to performance outcomes and is susceptible to coaching input. While research has amassed supporting benefits of an external focus of attention (EFA) on motor performance using verbal instruction, other studies have challenged the notion that an EFA is more beneficial than an internal focus of attention (IFA) for sport-related performance. Further, it is unclear what type of instructions may serve to direct an athlete to an EFA and, in particular, if coaching can utilize imagery to orient an athlete toward an EFA. In the present exploratory study, we evaluate the effectiveness of instruction to improve free-throw shooting performance with an emphasis on an EFA brought about by implementing techniques borrowed from the imagery literature. This was tested relative to an alternate approach with an IFA induced through an emphasis on technique, devised to more closely resemble input typical of coach-to-athlete instruction. Twenty-five male and female university basketball players completed both conditions in a fully counterbalanced within-subject design. Results confirmed that participants in the EFA imagery condition had greater shooting accuracy than in the IFA technique condition. The study provides initial evidence that EFA coaching can borrow from imagery techniques, though future research should elucidate the underlying mechanisms of the effect.

Skilled swimmers maintain performance stability under changing attentional focus constraints.

Focusing attention externally, rather than internally, has generally proved advantageous as it avoids interfering with self-organzing processes. However, some research has suggested that this may not necessarily be the case with highly skilled individuals who by definition possess a greater capacity to either adapt or maintain stability under varied task constraints. This study aimed to address this gap by comparing the performance of skilled athletes under internal and external attentional focus conditions using the swimming dive start as a task vehicle. Using a counterbalanced repeated measures design, skilled swimmers performed dive starts in conditions of differing attentional focus - internal and external attentional focus. Kinetic and kinematic variables were collected and statistical analyses conducted to compare differences between conditions. The results revealed no differences in outcome performance (relative peak power, horizontal velocity, and time to 5m) between internal and external focus conditions. However, remaining kinematic and kinetic measures revealed that all movement events occurred earlier in the movement sequence, suggesting superior self-organization of movement in the external focus condition. An external focus may be beneficial for the organization of movement control in skilled swimmers, but may not have an immediate impact upon the outcome of the task.

How Reliably Do Eye Parameters Indicate Internal Versus External Attentional Focus?

Eye behavior is increasingly used as an indicator of internal versus external focus of attention both in research and application. However, available findings are partly inconsistent, which might be attributed to the different nature of the employed types of internal and external cognition tasks. The present study, therefore, investigated how consistently different eye parameters respond to internal versus external attentional focus across three task modalities: numerical, verbal, and visuo-spatial. Three eye parameters robustly differentiated between internal and external attentional focus across all tasks. Blinks, pupil diameter variance, and fixation disparity variance were consistently increased during internally directed attention. We also observed substantial attentional focus effects on other parameters (pupil diameter, fixation disparity, saccades, and microsaccades), but they were moderated by task type. Single-trial analysis of our data using machine learning techniques further confirmed our results: Classifying the focus of attention by means of eye tracking works well across participants, but generalizing across tasks proves to be challenging. Based on the effects of task type on eye parameters, we discuss what eye parameters are best suited as indicators of internal versus external attentional focus in different settings.

Effects of attentional focus cues on lower extremity kinematics during inside of the foot soccer trap among expert soccer players

Numerous studies have demonstrated improved performance results for sport skills through attentional focus instructions. However, few studies have examined the effects of cueing on expert kinematic performance, and this is the first to assess cueing’s kinematic effects on expert soccer players performing .common techniques This study assessed the lower extremity kinematics of an inside of the foot soccer trap via motion capture cameras under different attentional focus cues to analyze how the cues affect the movement pattern among expert performers. 10 NCAA Division 1 soccer players trapped a launched ball on a scoring mat after receiving coaching cues inducing an internal, external, holistic, or control focus of attention. Statistical analysis revealed movement differences between the internal and external cue conditions for the ankle and knee joints during the movement. The difference at the knee was a steeper flexion followed by a correction and, at the ankle, a steeper flexion, both during the internal cue condition. Attentional focus cues inducing a conscious control of the movement may disrupt the movement patterns of highly skilled expert performers. Coaches should be acutely aware of the language they use in instruction, even among expert performers.

Mind over body: Creating an external focus for sport skills

ABSTRACT In a recent study examining the efficacy of different external foci (Singh and Wulf [2020]. The distance effect and level of expertise: Is the optimal external focus different for low-skilled and high-skilled performers? Human Movement Science, 73. https://doi.org/10.1016/j.humov.2020.102663), an external focus instruction referred to parts of the body (arms). Specifically, the image of a “platform” was used to describe the area between the wrists and elbows when passing a volleyball. The present study followed up on that study by addressing the question whether a focus on an image that represents a body part (platform) would be more effective than a focus on the body parts (arms) themselves (i.e. internal focus). In a within-participant design, novice volleyball players continuously passed a volleyball to a target on the wall. Participants completed eight 45-s trials under each of the external (“focus on your platform”) and internal focus (“focus on your arms”) conditions, performed in a counterbalanced order. The results showed that the total score (i.e. sum of scores over 45 s) was significantly higher when participants focused on the platform rather than their arms. Thus, invoking an image of an external object that “replaces” a body part can serve to promote an external focus that results in immediate performance advantages compared with an internal focus on the same body part. The findings suggest that instructors within a range of applied settings can creatively use such images to facilitate the performance of motor skills. Highlights The image of an object (“platform”) is used to promote an external focus in volleyball. Novice volleyball players pass a ball to a target with a focus on the platform versus arms. Passing accuracy is superior with an external (platform) relative to an internal focus (arms). Using the image of an object to “replace” a body part can promote an external focus of attention.

Optimizing Verbal Communication in the Instruction of Weightlifting to Weightlifting Naïve Athletes

ABSTRACT Motor learning theories should be used by coaches to optimally apply their technical knowledge of weightlifting. The OPTIMAL (Optimizing Performance Through Intrinsic Motivation and Attention for Learning) theory of motor learning highlights the importance of motivation and attention in the motor learning process, with enhanced expectancies and autonomy underpinning the athlete's motivation and an external focus of attention optimizing the athlete's attention. Better results are obtained by collaborating with athletes in an athlete-centered approach, giving them a sense of control and ownership of their learning process and making them feel able to succeed in the learning process. The success resulting from the right balance between the athlete's confidence and task difficulty leads to an increase in the athlete's self-efficacy, further improving the learning process. When instructing weightlifting, coaches should say as much as necessary, but as little as possible, while using an implicit coaching strategy that focuses on the task goal. Instructions and cues should have an external focus of attention, relative to the athlete's body, or use analogies to provide a clear task goal while using simple language associated with familiar motor skills.

Targeted Application of Motor Learning Theory to Leverage Youth Neuroplasticity for Enhanced Injury-Resistance and Exercise Performance: OPTIMAL PREP

Youth athletes are ideal candidates for novel therapeutic motor learning interventions that leverage the plasticity of the central nervous system to promote desirable biomechanical adaptions. We summarize the empirical data supporting the three pillars of the Optimizing Performance Through Intrinsic Motivation and Attention for Learning (OPTIMAL) theory of motor learning and expand on potential neurophysiologic mechanisms that will support enhanced movement mechanics in youth to optimize prevention programs for reduced injury risk, injury rehabilitation, exercise performance, and play (Prevention Rehabilitation Exercise Play; PREP). Specifically, we highlight the role of motivational factors to promote the release of dopamine that could accelerate motor performance and learning adaptations. Further, we detail the potential for an external focus of attention to shift attentional allocation and increase brain activity in regions important for sensorimotor integration to facilitate primary motor cortex efficiency. This manuscript serves to provide the most current data in support of the application of OPTIMAL PREP training strategies of the future.

Both a holistic and external focus of attention enhance the learning of a badminton short serve.

Attentional focus research consistently demonstrates a benefit of an external focus relative to an internal focus. However, this dichotomous comparison may oversimplify the variety of attentional focus strategies a learner uses when acquiring a motor skill. Recent research suggests a holistic focus of attention provides a similar benefit over an internal focus in performing a standing long jump, but the generalizability of this effect is unknown. The purpose of this study was to determine how an internal (IF), external (EF), and holistic focus (HF) and control condition impact the learning of a badminton short serve. Novice participants (N = 60) were randomly assigned to IF, EF, HF, or control groups. They practiced the badminton short serve for 150 trials over 5days and completed retention and transfer tests 48-h post-acquisition. Serve accuracy was analyzed in separate repeated-measures ANOVAs for acquisition and pretest/retention/transfer. All groups improved accuracy through acquisition with the HF group serving more accurately than the IF and control groups. In retention, the HF and EF group served more accurately than the control group, and in transfer, the HF group was more accurate than the IF and control groups. The present findings suggest a benefit of both a holistic and external focus in the learning of an accuracy-based task.
