Several studies explored the effects of attentional focus on resistance exercise, but their analysed outcomes most commonly involved surface electromyography variables. Therefore, the effects of attentional focus on resistance exercise performance remain unclear. The aim of this review was to perform a meta-analysis examining the acute effects of external focus vs. internal focus vs. control on muscular endurance. Five databases were searched to find relevant studies. The data were pooled in a random-effects meta-analysis. In the analysis for external vs. internal focus of attention, there were seven comparisons with 14 study groups. In the analyses for external focus vs. control and internal focus vs. control, there were six comparisons with 12 study groups. An external focus of attention enhanced muscular endurance when compared with an internal focus (Cohen’s d: 0.58; 95% confidence interval (CI): 0.34 and 0.82) and control (Cohen’s d: 0.42; 95% CI: 0.08 and 0.76). In the analysis for internal focus vs. control, there was no significant difference between the conditions (Cohen’s d: –0.19; 95% CI: –0.45 and 0.07). Generally, these results remained consistent in the subgroup analyses for upper-body vs. lower-body exercises. From a practical perspective, the results presented in this review suggest that individuals should use an external focus of attention for acute enhancement of muscular endurance.

Learning And Performance

Performance benefits exist for an external focus of attention compared with an internal focus of attention for performance and learning (Wulf, 2013). It is unknown, however, if varying the number of verbal cues affects learning and performance. Focus of attention and the number of verbal cues were manipulated during a simulated handgun-shooting task. For the internal focus conditions, participants were told to focus on their hand, arm, and wrist, whereas the external focus instructions were to focus on the gun, gun barrel, and gun stock. To manipulate the number of verbal cues, participants received instruction to focus on a single verbal cue or multiple verbal cues. Shooting performance was assessed at baseline, acquisition, and at two separate retention phases (immediate, delayed) that included transfer tests. Participants completed the NASA—Task Load Index to assess workload following all trials. Participants who received one verbal cue performed significantly better during immediate retention than those who received three verbal cues. Participants who used external focus of attention instructions had higher performance and reported less workload at delayed retention compared to those who used internal focus instructions. This research provides further support for the benefits of an external focus and highlights the importance of minimizing the number of verbal cues.

Recent evidence supports advantages of an external focus of attention on learning motor skills, however, there is a need to retest these finding for children and comparing them with adults. Thus, the purpose of current study was to determine the effect of different attentional focus on learning a motor skill in children and adults. Thirty children (8-12 year) and thirty adults (25-42 years) were randomly assigned to one of four groups: (1) Children external focus of attention (EFA), (2) Children- internal focus of attention (IFA), (3) Adults- External focus of attention (EFA), (4) Adults- internal focus of attention (IFA). Following initial instructions and task demonstration, participants performed 60 darts throwing in six blocks and 24 hours later performed 10 additional throws for retention test. Results revealed that children benefited from EFA and IFA instruction in the same manner, however, adults benefited from EFA more than IFA instruction. Future studies should continue to examine effects of different attentional focus on other skills.

The present experiment was designed to test the predictions of the constrained-action hypothesis. This hypothesis proposes that when performers utilize an internal focus of attention (focus on their movements) they may actually constrain or interfere with automatic control processes that would normally regulate the movement, whereas an external focus of attention (focus on the movement effect) allows the motor system to more naturally self-organize. To test this hypothesis, a dynamic balance task (stabilometer) was used with participants instructed to adopt either an internal or external focus of attention. Consistent with earlier experiments, the external focus group produced generally smaller balance errors than did the internal focus group and responded at a higher frequency indicating higher confluence between voluntary and reflexive mechanisms. In addition, probe reaction times (RTs) were taken as a measure of the attention demands required under the two attentional focus conditions. Consistent with the hypothesis, the external focus participants demonstrated lower probe RTs than did the internal focus participants, indicating a higher degree of automaticity and less conscious interference in the control processes associated with the balance task.

Context: The bodyweight squat exercise is a common component for treatment and prevention of patellofemoral pain; however, it can also place a high load on the patellofemoral joint. Restricting anterior motion of the knees relative to the toes during squatting appears to reduce patellofemoral loading. However, exercise professionals typically rely on verbal instructions to alter squat technique. Objective: To evaluate the influence of verbal instructions regarding squat technique on patellofemoral joint loading. Design: Cross-sectional study. Setting: Motion analysis laboratory. Participants: Eleven uninjured females. Intervention: Participants performed bodyweight squats before (baseline) and after receiving verbal instructions to limit anterior knee motion. Two different types of verbal instruction were used, one intended to promote an internal focus of attention and the other intended to promote an external focus of attention. Three-dimensional kinematics and kinetics were recorded using a multicamera system and force plate. Main Outcome Measures: Sagittal plane patellofemoral joint forces and stress were estimated using a musculoskeletal model. Results: Participants demonstrated a reduction in patellofemoral joint forces (35.4 vs 31.3 N/kg; P = .01) and stress (10.7 vs 9.2 mPa; P = .002) after receiving instructions promoting an internal focus of attention, compared with their baseline trials. Participants also demonstrated a reduction in patellofemoral joint forces (35.4 vs 32.3 N/kg; P = .03) and stress (10.7 vs 9.6 mPa; P = .04) after receiving instructions promoting an external focus of attention (vs baseline). However, there were no significant differences in patellofemoral forces (P = .84) or stress (P = .41) for trials performed with an internal versus external attentional focus. Conclusion: It appears that verbal instruction regarding knee position influences patellofemoral joint loading during squatting.

Two experiments are reported in which skilled musicians playing different instruments performed a piece of their choice under various attentional focus conditions. In the external focus condition, they were asked to focus on playing for the audience and the expressive sound of the music. In the internal focus condition, they were asked to focus on the precision of their finger movements (or lip movements for singers) and correct notes. In the control condition, they were asked to play the way they normally did. Expert raters evaluated the musicians’ performances for both musical expression and technical precision. In Experiment 1, external focus instructions enhanced musical expression relative to both internal focus and control conditions. There was no effect on technical precision. In Experiment 2, raters were given more detailed evaluation criteria. An external focus again led to superior musical expression compared with internal focus and control conditions. In addition, technical precision was higher within the external relative to the internal focus condition. The findings show that the advantages of focusing on the intended movement effect (i.e., externally) generalize to experienced musicians. Music teachers could offer their students specific recommendations for focus of attention during training and in concert situations to optimize learning and performance.

This study examined the interaction between a skill/extraneous attentional focus and an internal/external focus of attention using a dual-task paradigm. Thirty-two low-skill participants completed a primary dart-throwing task with their dominant arm while simultaneously performing a secondary arm-stabilizing task with their nondominant arm. Two aspects of the participants’ attentional focus were manipulated: skill versus extraneous focus and external versus internal focus. Participants completed 120 trials across four conditions created by combining the dimensions of the two variables. Performance on the primary task was assessed by measuring throwing accuracy and the kinematics of the throwing action. Results indicated that accuracy improved under the external, skill-oriented condition relative to all other conditions; no differences between the remaining conditions were observed. These findings suggest that an external, skill-oriented focus of attention is needed to facilitate performance improvements in novices.

External focus of attention (EFA) and internal focus of attention (IFA) represent commonly used strategies to instruct subjects during exercise. Several studies showed EFA to be more effective than IFA to improve motor performance and learning. To date the role of these strategies on motor performance during finger movement was less studied. The objective of the study was to investigate motor performance, patient’s preference induced by IFA and EFA, and the focus during control condition. Ten healthy right-handed participants performed a finger movement task in control, EFA, and IFA conditions (counterbalanced). Errors, patient’s preference, and type of attentional focus spontaneously adopted during the control condition were recorded. EFA determined less error (p<0.01) compared to control and IFA. Participants preferred EFA against IFA and control condition. In the control group 10% of subjects adopted a purely EFA, 70% of subjects adopted a purely IFA, and 20% of subjects adopted a mixture of the two foci. Our results confirm that EFA is more effective than IFA and control in finger movement task. Due its clinical relevance, the interaction between attention and finger movement should be further investigated.

Body Positioning

The present study followed up on previous findings showing greater movement efficiency when performers adopt an external relative to an internal focus of attention. We used a swimming task to examine if those effects were dependent of the task component. Specifically, the aim of this study was to investigate the effects of attentional focus related to breathing and body position on crawl swim performance. Eighteen young adults (20.1 years old; ±3.0) participated in the present study. The task required participants to cover a 16 m swimming crawl, as fast as possible. Participants were asked to “keep body at water line” (external focus) or to “keep your body horizontal” (internal focus), and to “breathe when hand leaves the water” (external focus) or “breathe when head turns sideways” (internal focus). The dependent variable was time spent to cross the swimming pool in seconds and tenths of seconds. Two-way ANOVA (2 focus X 2 components) did not show any significant differences between external and internal focus in both components. The results led to the conclusion that when the focus was related to body position and breathing, the external and internal attentional focus had similar effects on performance of the crawl swim.

The present study examined whether the previously observed benefits of an external focus of attention (i.e., focusing on the movement effect), relative to an internal focus (i.e., focusing on one's body movements) and control conditions, would generalize to tasks requiring maximum force production, such as jumping. In two experiments, participants performed a vertical jump-and-reach task. A Vertec™ measurement device was used to determine jump-and-reach height. Participants performed under three conditions in a within-participant design: External focus (i.e., focus on the rungs of the Vertec that were to be touched), internal focus (i.e., focus on the finger, with which the rungs were to be touched), and control conditions (i.e., focus on jumping as high as possible). Experiment 1 showed that participants' jump-and-reach height was greatest with an external focus. Those results were replicated in Experiment 2. In addition, it was observed that the vertical displacement of the center of mass was greater under the external focus condition, compared to the other two conditions. This suggests that participants jumped higher by producing greater forces when they adopted an external focus. These findings indicate that the previously shown benefits of an external attentional focus generalize to tasks requiring maximal force production

The performance benefits of adopting an external relative to an internal focus of attention have been demonstrated for many different targeting and balance tasks. No study has examined attentional focus effects for interceptive motor skills. Also, the majority of studies have used adult participants. In this study, children (mean age: 8.75 years, SD=0.79; 15 girls, 9 boys) were required to catch tennis balls in the frontal plane under the external focus (EF), internal focus (IF), and control (Cont) conditions. Participants were asked to stand behind a yellow line (2 × 100 cm), 15 m apart from a tennis ball throwing machine. In a within-participant design, participants performed 10 trials under each IF (“concentrate on your hands”), EF (“concentrate on the ball”), or Cont (no focus instructions) conditions. The order of conditions was counterbalanced. Performance data were analyzed using a one-way analysis of variance (ANOVA) with repeated measures on attentional focus conditions (internal, external, and control) (alpha=.05). Catching performance was significantly different&nbsp;and more effective in the EF (M=1.53, SD=0.25) than in the IF (M=1.39, SD=0.35) condition, while both EF and IF were not significantly different from the Cont (M=1.49, SD=0.28) condition. The current findings suggest that the external focus of attention is more beneficial, compared to the internal focus, to motor performance of an interceptive skill in children.
