1. Introduction
Soccer is a dynamic sport in which two teams of 11 players, along with the ball, are in constant motion. Through a combination of dribbling, passing, and shooting, each team attempts to maneuver the ball around and between opponents to score goals. While elite players are often celebrated for their dribbling and shooting skills, passing is the most frequently executed skilled action during games [
1,
2,
3]. Notably, teams that pass more frequently and more effectively than their opponents are more likely to win [
3,
4,
5,
6]. An effective pass typically involves receiving and controlling the ball, followed by delivering an accurate pass—often under pressure from defenders trying to limit options or regain possession. Players generally have a preferred (dominant) foot for controlling and passing [
7,
8], but the optimal foot choice is highly context-dependent. For instance, the trajectory of the incoming ball and the positioning of nearby defenders may determine which foot is best suited for control. Likewise, the player’s body orientation relative to both the ball and the target can influence which foot is best for passing. Being able to pass accurately with either foot is therefore a highly valuable skill [
9]. To perform consistently under varying conditions and pressures, players must be proficient in both controlling and passing with either foot.
Another key element of effective passing is decision-making, particularly identifying the best passing option. Teammates may be positioned in front, behind, or to either side, requiring players to quickly scan their surroundings—often while under pressure—to make informed decisions. The timing of scanning relative to ball reception can significantly impact performance. Players who scan before receiving the ball tend to possess it for less time [
10,
11], make more switches of play and forward passes [
12], and complete a higher percentage of passes [
13], all of which contribute to maintaining possession and creating attacking opportunities. Given the importance of passing, numerous assessments have been developed to measure passing ability [
14,
15,
16,
17,
18]. However, most do not require players to visually scan their environment, even when offering multiple target options. For example, the Loughborough Soccer Passing Test (LSPT) [
16] requires players to pass to four rebound boards but uses auditory cues to signal the next target. More recently, Hunter and colleagues [
19] introduced three passing tests that incorporate visual scanning using rebound boards and an integrated light system. These tests require players to visually identify the next target between each pass, simulating more realistic match demands. The tests successfully differentiated between first- and reserve-team players and predicted performance in small-sided 3v1 Rondo games (Hunter and colleagues [
19]). In these tests, players had to control and pass the ball across various angles (e.g., 60°, 120°, or 180° to the left or right) while adapting to different scanning demands. Although these tests revealed performance differences among players, the mechanisms underpinning high performance remain unclear. Specifically, which techniques enable more effective control and passing?
Some techniques are likely to be more efficient than others, and to explore this, we first define foot orientation in relation to the incoming ball. For example, consider a left-sided midfielder with their back to the sideline receiving a forward pass from a central defender. In this case, the left foot is the back foot (farthest from the ball’s path), and the right foot is the front foot (closest to the ball). If the player controls the ball with their front (right) foot and passes with their back (left) foot, this is a front–back technique. However, the back–front sequence—controlling with the back foot and passing with the front foot—is likely the most efficient in many situations. In our example, the player allows the ball to travel across the body, controls it with the back (left) foot toward the target, and immediately passes with the front (right) foot. With an effective first touch, no additional steps are needed: the back foot is used to control the back and is then placed beside it, and the front foot executes the immediate pass [
20,
21,
22]. In contrast, other techniques often involve an extra step. For instance, in the front–front technique, the player controls the ball with the front foot, places it down, steps with the back foot, and only then passes with the front foot. This extra movement likely reduces efficiency compared to the back–front sequence. While using the dominant foot may be generally better (and preferred) than with the nondominant foot [
23,
24,
25], the time costs associated with an extra step to pass the ball (when controlling first with their dominant foot) may play a greater role in determining passing performance—though this remains to be tested.
The aim of this study was to investigate how the technique a player uses to control and pass the ball influences performance. We video-recorded skilled players from a Brazilian youth academy as they completed the passing tests developed by Hunter and colleagues [
19]. Each touch (control and pass) was coded based on foot orientation (e.g., front–back, back–front) and foot dominance (dominant or nondominant). For instance, if a right-footed player controlled the ball with the left foot and passed with the right, this was classified as a nondominant–dominant sequence. We predicted that (i) the most common technique used would vary with pass direction, due to a preference for the dominant foot; (ii) performance would differ across techniques, with the back–front sequence the fastest; and (iii) scanning before receiving the ball would lead to better performance.
  2. Methods
  2.1. Participants
Participants were members of the under-12 (n = 23) and under-13 (n = 22) squads from an elite Brazilian youth academy, whose senior team at the time of data collection competed in Brazil’s Série A competition. All players were of a high standard and competed in local state competitions and some national club tournaments. The average age of participants was 12.8 years (SD = 0.58; range = 11.64–13.55). Written consent was obtained from guardians in accordance with the ethical standards of the University of Queensland (Australia) and the University of São Paulo, Ribeirão Preto campus (Brazil). Individual players could refuse to take part if they chose.
  2.2. Study Design
Players’ passing ability was assessed over seven one-hour sessions, with each player participating in one session. During testing, players completed three passing tests of varying complexity, designed by Hunter and colleagues [
19]. Each player completed one trial of the 120-degree test and two trials each of the 180-degree and 360-degree tests. The order of the 180-degree and 360-degree tests alternated between sessions. Within each session, players alternated between these two tests until both were completed twice, with the 120-degree test always performed last (note: two players did not complete the 120-degree test). Each player’s foot dominance was also recorded.
  2.3. Passing Tests
We used the three passing tests described in Hunter and colleagues [
19] that employed specially constructed rebound boards measuring 1.1 m in width and 0.5 m in height. Each board featured a central hole with a 5 cm diameter (
Figure 1). Directly behind these openings, a RoxPro vibration/light sensor (A-Champs Inc., Barcelona, Spain) was installed. The sensors illuminated to indicate the next target in a predetermined sequence. At the start of a trial, players struck the ball toward the board displaying the initial light. Once contact was made, that light switched off, and another light instantly activated on a different board to signal the subsequent target. This cycle continued until the trial ended. Participants were required to control the ball with at least one touch before making each pass, though they were free to choose the foot and technique employed. If a pass failed to reach the target or an error occurred (see details below), the player was given a replacement ball to resume the attempt. The RoxPro system logged the interval between consecutive successful board strikes. These timings were later expressed as passes per minute, providing a performance index for each participant [
19].
In the 120-degree test, two rebound boards were arranged 120° apart, both angled toward a shared focal point located 5 m away. Players started each trial from this focal point, with the initial target randomized between individuals. Each participant completed ten passes to either side, excluding the very first pass, resulting in a total of 20 attempts. Because only two boards were involved and the next target was always predictable, this drill was the least demanding in terms of decision-making—it required no visual search. Nonetheless, success still depended on precise passing and clean ball control.
For the 180-degree test, four boards were positioned along a 180° arc, each spaced 60° apart and facing the same central point 5 m away. Depending on the programmed light sequence, players had to rotate their bodies through angles of 60°, 120°, or 180° before striking the next pass. Each directional turn was repeated three times, amounting to 18 passes. Beyond the technical skills required in the 120-degree task, this test challenged players to scan for the next target. The most effective approach was to scan immediately after hitting the current board, before receiving the return ball, enabling a first touch that set up an accurate, rapid pass. Waiting to scan until after ball reception was possible, but it demanded more versatile control to cope with multiple directional options.
The 360-degree test involved three boards distributed evenly at 120° intervals around a complete circle, all directed toward the same focal point and set 5 m away. Players carried out ten passes to each side (20 in total). This test combined the technical requirements of the 120-degree setup with the need to anticipate the next target in advance of receiving the ball. If scanning was delayed until after the first touch, performance could vary: a well-directed touch might assist in making the next pass quickly, while a poorly oriented one could force additional adjustments of body or ball position.
All trials were video-recorded, and each pass was classified as successful, erroneous, or invalid. Invalid attempts occurred when players attempted a one-touch pass; these were excluded from analysis. Errors included missed boards or miscontrolled balls requiring a replacement ball. Because such mistakes reflected individual performance, a consistent penalty was applied. Specifically, the median pass time across across all tests—4.60 s—was assigned whenever a replacement ball was needed. This ensured a standardized time cost approximating the typical duration for missing, receiving a new ball, and resuming play.
  2.4. Video Analysis
All trials were recorded at 30 frames per second (GoPro), and a single experienced researcher (35 years in playing, coaching, or soccer research) analyzed the footage using Kinovea software (version 0.8.15) [
26]. For each pass, the following data were coded: (i) the foot used to control and pass the ball (categorized as dominant/nondominant and front/back), (ii) the number of touches taken between passes, and (iii) the outcome of each pass (hit, error, or invalid). In addition, (iv) the direction of the next pass in relation to foot dominance was recorded. For example, in the 180-degree test, if a player received the ball from board 2 and the next target was board 4 (
Figure 1B), a pass to the right was coded as a dominant-side pass for right-footed players and a nondominant-side pass for left-footed players (
Figure 2). In the 360-degree test, whether players turned in the correct direction toward the next target (yes or no) was also recorded. For instance, if the ball returned from board 1 and the next target was board 2 (
Figure 1C), turning to the left was incorrect. First-time passes were deemed invalid.
We also recorded whether a player completed a successful visual scan before receiving the ball during the 360-degree test. A successful scan had two criteria. First, the player scanned in a way that clearly indicated they had correctly identified the next target before receiving the ball. With only two possible targets on the 360-degree test, an appropriately timed scan of either board was considered successful, as the player would either see the next target board with the light on or the non-target board with light off. Either scenario would inform players of the next target board. Second, the scan occurred early enough to allow an effective first touch toward the target. The most obvious sign was when players looked up to identify the target and then returned their gaze to the ball in time to take a first touch in the correct direction. Late or ambiguous scanning during or after ball reception was not considered successful.
A random sample of 5 trials (totaling 85 valid passes) was re-analyzed for scanning behavior. Intra-rater reliability was excellent (Cohen’s Kappa = 0.876, p < 0.001).
  2.5. Statistical Analysis
On the 120-degree and 180-degree tests, we first used chi-square tests [
27] to assess whether technique choice was associated with pass direction (prediction i). Then, to examine performance differences between techniques (prediction ii), we ran linear mixed-effects models [
28] for each test, estimating the effect of foot orientation (e.g., back–front) on passes per minute (simple model). Only valid (target-hitting) passes were included, and player ID was entered as a random effect to account for repeated measures. To assess whether performance varied depending on the foot used, we ran a second set of linear mixed-effects models that included pass direction and an interaction term between technique and foot orientation (full model).
On the 360-degree test, players who did not scan still had a 50% chance of turning in the correct direction by chance, meaning scanning might not always yield a performance benefit in terms of passes per minute. Therefore, we assumed scanning affected performance through a two-step process: (i) scanning increased the likelihood of turning in the correct direction, and (ii) turning in the correct direction improved performance. To test this, we used a generalized linear mixed-effects model (binomial) [
28] to determine whether scanning (yes/no) increased the odds of turning correctly (yes/no), including player ID as a random effect. Next, we used a linear mixed-effects model to estimate how pass direction and turning correctly (yes/no) influenced passes per minute, including an interaction term and player ID as a random factor.
We further examined whether turning correctly influenced touch count by applying another generalized linear mixed-effects model (binomial), with outcome coded as one touch vs. more than one touch. Finally, we used a generalized linear mixed-effects model to determine whether turning in the correct direction (yes/no) and pass direction influenced whether the next pass was successful (hit/miss), including interaction terms and player ID.
All analyses were conducted using R (version 4.1.0), with the stats [
27], lmerTest [
28], and emmeans [
29] packages. Prior to analysis, the distribution of the data for each test was checked with a Shapiro–Wilk Normality test. The 120-degree test (
p = 0.68) and 360-degree test (
p = 0.33) data were normally distributed, and the 180-degree test data showed mild positive skewness (
p < 0.001). No data transformations were deemed necessary as linear mixed-effects models are robust to non-normal assumptions [
30].
  4. Discussion
This study investigated how technique and visual scanning influenced passing performance in elite youth soccer players. As predicted, we found the technique players used was associated with the direction of the pass, reflecting a clear preference for their dominant foot. This bias was especially pronounced when passing to the nondominant side and often led players to select control–pass combinations that were not the most efficient. In addition, performance differed across techniques, with specific techniques consistently leading to faster, more accurate passes. We also found that players who scanned before receiving the ball in the 360-degree test performed better. Players who scanned turned in the correct direction more often, took fewer touches, and hit the target more often. Taken together, these findings highlight the importance of developing not only technical skills but also perceptual and decision-making abilities in youth players.
Specific passing techniques consistently outperformed others in both the 120- and 180-degree tests, and their effectiveness often depended on the direction of the pass relative to the player’s dominant foot. In the 120-degree test, the most effective technique was back–front, followed by back–back, front–front, and front–back. Despite its superior performance, back–front (dominant–nondominant) was only used 33% of the time when passing to the dominant side, while back–back (dominant–dominant) was used 58%, suggesting a strong preference for staying on the dominant foot. This preference became even more evident when passing to the nondominant side. In those cases, players used back–front (nondominant to dominant) 66% of the time, which is double the rate used when passing to the dominant side. Less efficient techniques like front–front (dominant–dominant) were still used 23% of the time, and the potentially more efficient back–back (nondominant–nondominant) was rarely chosen. These patterns reflect a consistent bias toward the dominant foot, even when it limits performance. In the 180-degree test, the highest-performing techniques were again back–back and back–front. When passing to the dominant side, players used one of these two techniques 77% of the time, with back–back (dominant–dominant) alone accounting for 57%. However, when passing to the nondominant side, back–back (nondominant–nondominant) was used just 7% of the time. Players often relied on the slower front–front (dominant–dominant) technique when passing to the nondominant side, used in 34% of passes, which further shows a tendency to prioritize foot preference over technical efficiency. Interestingly, reliance on the dominant foot only improved passing performance in the 180-degree test, not the 120-degree test. Players using back–front or front–front techniques in the 180-degree test performed better when passing when using their dominant foot. This is likely due to the greater cognitive and technical demands of the 180-degree task, which required additional scanning requirements and the ability to pass in multiple directions with less predictable ball control. This increased complexity likely led to detectable performance differences between the dominant and nondominant foot, with the dominant being more proficient [
23,
24,
25].
As the perceptual and cognitive demands of the tests increased—such as in the 180- and 360-degree tests—players were more likely to revert to familiar but suboptimal strategies, such as consistently using their dominant foot. This behavioral pattern reflects a well-documented phenomenon in motor learning: when under pressure or faced with uncertainty, players often default to overlearned or automatic motor responses, even if these are not the most effective for the task at hand [
31,
32,
33]. In our study, the tendency to select dominant-foot techniques despite poorer performance suggests that increased task complexity may have overwhelmed some players’ ability to process information and adapt their motor responses. This supports broader theories in skill acquisition, which argue that expert performance relies not only on motor proficiency, but also on the ability to manage cognitive load and flexibly apply the most efficient solution in response to contextual demands [
31,
32,
33]. These insights emphasize the importance of training approaches that simulate cognitive pressure, helping players develop the capacity to maintain adaptable and efficient decision-making under realistic game constraints.
Scanning is important for better passing performance in games because it allows players to observe their surroundings before receiving the ball. This early awareness helps them select a target location and plan their next move in advance, enabling quicker and more accurate passing decisions [
10,
11,
13]. Our results demonstrate that scanning provides clear performance benefits in a controlled passing test. On the 360-degree test, players successfully scanned before receiving the ball less than 30% of the time, suggesting the task was particularly challenging for this age group. Players who did scan were more likely to turn in the correct direction, reduce the number of touches needed, and increase the likelihood of hitting the target—ultimately resulting in a higher passes-per-minute rate. Although our data clearly show that players who scan before receiving the ball perform better in the 360-degree test, it remains to be tested whether these benefits directly translate to game situations. Improving the ability to scan while the ball is moving toward the player is likely to further support effective passing in match scenarios. Importantly, our tests could be adapted into training environments to encourage and develop scanning behaviour. By implementing structured tasks that require players to scan and by tracking their performance over time, coaches can foster this critical skill. While an initial decline in performance is expected due to the added cognitive load of managing a second task, this challenge is likely to promote long-term improvements. As scanning becomes more automatic, players could experience enhanced passing efficiency and decision-making under pressure.
Scanning is not merely a passive act of “looking,” but an active process of detecting affordances—that is, opportunities for action that emerge based on the player’s capabilities and the game context [
34]. This idea is linked to the concept of perception–action coupling, which is a core principle in motor control and ecological dynamics [
34,
35,
36]. In soccer, affordances may include passing gaps, spaces to turn, or the positioning of teammates and defenders. These are not static features but are perceived in relation to the player’s own movement possibilities. For example, a narrow gap for passing may afford a quick through ball for a technically skilled player, but not for one with less performance under pressure. In our study, as task complexity increased—from the 120-degree to the 360-degree test—the demand on players to perceive and act upon such affordances also increased. The performance drop-off in the 360-degree test suggests that many players struggled to maintain effective perception-action coupling under higher spatial and temporal uncertainty. In contrast, players who successfully scanned before receiving the ball were more likely to identify useful affordances early, make correct turning decisions, and complete quicker, more accurate passes. This further emphasizes the importance of training environments that integrate perceptual demands with motor execution to support the development of more adaptive, game-relevant skills.
While our tests were conducted without defenders, they provide a controlled and repeatable way to assess individual technical habits, allowing for detailed analysis of a player’s strengths and deficiencies. These insights can be used to design personalized training interventions. For example, if a player shows a consistent bias toward dominant-foot passing in the 180-degree test, coaches can introduce drills that promote the use of back–back or back–front techniques with the nondominant foot. Similarly, a player’s scanning frequency in the 360-degree test can be tracked before and after targeted scanning exercises to assess improvement. This diagnostic approach allows for tailored training plans that address not just technical execution, but also perceptual and decision-making skills—core aspects of modern coaching philosophy. Over time, these tests can also be used to monitor progress, helping players and coaches identify which interventions are most effective and adjust training accordingly. While the direct translation of test performance to match outcomes still requires further validation, the structured nature of these assessments offers a valuable tool for individualized player development.
Although this study sample was composed of only U12–U13 boys, our findings are likely applicable to the wider soccer community, regardless of sex or playing ability. Different groups of players (e.g., elite adults or novice players) may perform better or worse overall than our group of players on these tests (passes/min), but the trends we identified here are likely consistent across all groups. For example, the techniques available to control and pass the ball (e.g., back–front or front–front) are consistent across all players. Similarly consistent is the additional step (and time cost) involved if a player chooses to use the front–front technique instead of the back–front technique. Therefore, the performance differences we found among techniques are likely applicable to all soccer players. One may argue that elite adult players would not display the same bias toward their dominant foot found here. However, as this bias is present in the world’s best players in matches [
7,
8,
9], it would likely appear if these players were to do these tests. The benefits of scanning on the 360-degree test are also likely to be consistent across all players. For example, if a player does not scan, the likelihood of them turning in the correct direction is still 50%, regardless of their playing ability—and the associated performance costs for turning incorrectly are also likely to be consistent across different player abilities. However, the prevalence of scanning on our tests is likely to increase as playing ability and experience increase, yet this remains to be tested.
Our results were limited by small sample sizes in some instances. For example, on the 120-degree test, the simple linear mixed-effects model found the back–front sequence to be faster than all other techniques. However, when the pass direction was included in the model, there was no performance difference between the back–front and back–back techniques. This discrepancy may be explained by small sample sizes, particularly for passes toward the nondominant side. While one could confidently argue that the back–front technique was faster than the back–back technique when passing to the nondominant side, the back–back technique was used only 5% of the time. Identifying statistically significant differences in this scenario is inherently difficult. Future research could instruct players to use certain techniques to obtain more balanced datasets and better identify performance differences among techniques. However, this comes with a cost of not identifying biases towards certain techniques or foot usage (dominant vs. nondominant).
