The final sample consisted of 14 neurotypical children who regularly practiced tennis, 12 boys (85.71%) and 2 girls (14.29%), with a mean age of 10.29 years (±0.83). The 3x3 ECRc design was used to ev
working memory. To minimize residual effects between experimental conditions, a minimum washout period of seven days was adopted. The sample consisted of young tennis athletes, aged between 9 and 11 y
(ii) low complexity (LC)
and (iii) no complexity (control – SC). In the HC condition, the cognitive parameters of the series with four blows followed the following sequence: 1. Change of order
2. Reversal of order
3. Change of order
4. Reversal of order. In the LC condition, the working memory parameters were organized as follows: 1. Retention of order
3. Retention of order
4. Reversal of order. In the SC condition, there was no manipulation of the working memory parameters
all blows remained exposed on the plate in the same order, without a minimum exposure time. Unlike the HC and LC conditions, in which the stimuli were exposed for 10 seconds, in the SC condition there

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: The effect of the tennis task intervention during structured sessions is expected to be evaluated by measuring the increased frequency of the Total Cognitive Error (ECTotal) notational analysis determined by cognitive enrichment on working memory under High Complexity (AC), Low Complexity (BC), and No Complexity (SC) conditions;Outcome found1: A high number of occurrences was observed through the frequency of the notational analysis of Total Cognitive Error (ECTotal) in the High Complexity (AC) and Low Complexity (BC) conditions compared to the No Complexity (SC) condition during the structured sessions determined by cognitive enrichment on working memory with post-hoc comparisons with Tukey adjustment indicating significant differences between all conditions (HC - NC: p < 0.01; HC - NC: p < 0.001; NC - NC: p < 0.05) | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome 2: The effect of tennis task intervention during structured sessions is expected to be evaluated by measuring the increased frequency of Cognitive Error – Incongruent Stroke Selection Error (EGI) and Cognitive Error – Total Stroke Stoppage Error (EPG) determined by cognitive enrichment on working memory under High Complexity (AC), Low Complexity (BC), and No Complexity (SC) conditions;Outcome found 2: A high number of occurrences were observed through the frequency of notational analysis of Cognitive Error – Incongruent Stroke Selection Error (EGI) and Cognitive Error – Total Stroke Stoppage Error (EPG) in the High Complexity (AC) condition compared to the Non-Complexity (SC) condition during structured sessions determined by cognitive enrichment on working memory with post-hoc comparisons with Tukey's adjustment revealed significant differences only between the AC and SC conditions (P = 0.003);Expected outcome 3: The effect of the tennis task intervention in sessions is expected to be evaluated at three time points (pre-test, 1st and 2nd post-test) through the decrease in performance on the Corsi Block-Tapping computerized neuropsychological task for the group factor, longest correct sequence (span), and product determined by cognitive enrichment on working memory under High Complexity (AC), Low Complexity (BC), and No Complexity (SC) conditions;Outcome found 3: A similar variation was observed in the three evaluated time points (pre-test, 1st and 2nd post-test) through the performance of the Corsi Block-Tapping computerized neuropsychological task, determined by cognitive enrichment on working memory in accuracy for the group factor, in the longest correct sequence for time (span), and in the group*time product (p < 0.05). However, Tukey's post-hoc test revealed a significant difference exclusively between the Low Complexity (BC) and No Complexity (SC) conditions in accuracy | — |
