Recent studies suggest that a single bout of exercise can lead to transient performance improvements in specific cognitive domains in children. However, more knowledge is needed to determine the key exercise characteristics for obtaining these effects and how they translate into real-world settings. In the present study, we investigate how small-sided football games of either high or moderate-intensity affect measures of inhibitory control in a school setting. Eighty-one children (mean age 11.8, 48 boys) were randomly allocated to three groups performing 20-min of high-intensity small-sided real football games (SRF), moderate-intensity small-sided walking football games (SWF) or resting (RF). Behavioural measures of inhibitory control and neurophysiological measures of attention (P300 latency and amplitude) were obtained during a flanker task performed at baseline and 20 minutes following the intervention. Retention of declarative memory was assessed in a visual memory task 7 days after the intervention. Measures of inhibitory control improved more in children performing SRF compared to SWF 19ms, 95% CI [7, 31ms], (p=0.041). This was paralleled by larger increases in P300 amplitudes at Fz in children performing SRF compared both to RF in congruent (3.54μV, 95% CI [0.85, 6.23 μV], p=0.039) and incongruent trials (5.56μV, 95% CI [2.87, 8.25 μV], p<0.001) and compared to SWF in incongruent trials (4.10μV, 95% CI [1.41, 6.68 μV], p=0.010). No effects were found in measures of declarative memory. Together this indicates that acute high-intensity small-sided football games can transiently improve measures of inhibitory control and neurophysiological correlates of attention. Intense small-sided football games are easily implementable and can be employed by practitioners, for example, during breaks throughout the school day.

Objective: Recent studies have shown promising effects of physical activity on cognitive function, but there is a need to investigate this link in real-life settings such as schools. Hence, the objective of the present pilot study was to investigate whether the school-based physical activity programme “FIFA 11 for Health” for Europe could improve cognitive performance in preadolescent Danish children. Methods: The pilot study used an 11-week cluster-randomised intervention study design. School classes were randomly assigned to either a control group (CG) (n = 93 children, age = 11.8, s = 0.2 years), which performed the obligatory daily school-based physical activity (5 × 45 minutes per week); or an intervention group (IG) (n = 838 children, age = 11.9, s = 0.4 years), which substituted 2 × 45 minutes per week of the daily school physical activity with the “FIFA 11 for Health” for Europe programme. The programme combines small-sided football games, drills and health education. Cognitive performance was evaluated at baseline and follow-up. Results: The IG improved their cognitive performance compared to the CG for psychomotor function (56, sx– = 22 ms, p < .001), attention (39, sx– = 17 ms, p = .012) and working memory (79, sx– = 35 ms, p = .020). Conclusion: This pilot study provides evidence that the school-based physical activity programme “FIFA 11 for Health” for Europe can improve cognitive performance in preadolescent Danish schoolchildren. Future studies should attempt to disentangle the effects of “FIFA 11 for Health” for Europe on cognitive performance by investigating the characteristics of the programme’s physical activity.

Objective: An emerging field of research indicates that physical activity can benefit cognitive functions and academic achievements in children. However, less is known about how academic achievements can benefit from specific types of motor activities (e.g., fine and gross) integrated into learning activities. Thus, the aim of this study was to investigate whether fine or gross motor activity integrated into math lessons (i.e., motor-enrichment) could improve children's mathematical performance. Methods: A 6-week within school cluster-randomized intervention study investigated the effects of motor-enriched mathematical teaching in Danish preadolescent children (n = 165, age = 7.5 ± 0.02 years). Three groups were included: a control group (CON), which received non-motor enriched conventional mathematical teaching, a fine motor math group (FMM) and a gross motor math group (GMM), which received mathematical teaching enriched with fine and gross motor activity, respectively. The children were tested before (T0), immediately after (T1) and 8 weeks after the intervention (T2). A standardized mathematical test (50 tasks) was used to evaluate mathematical performance. Furthermore, it was investigated whether motor-enriched math was accompanied by different effects in low and normal math performers. Additionally, the study investigated the potential contribution of cognitive functions and motor skills on mathematical performance. Results: All groups improved their mathematical performance from T0 to T1. However, from T0 to T1, the improvement was significantly greater in GMM compared to FMM (1.87 ± 0.71 correct answers) (p = 0.02). At T2 no significant differences in mathematical performance were observed. A subgroup analysis revealed that normal math-performers benefitted from GMM compared to both CON 1.78 ± 0.73 correct answers (p = 0.04) and FMM 2.14 ± 0.72 correct answers (p = 0.008). These effects were not observed in low math-per

Multisensory learning paradigms can positively affect learning of various cognitive skills (Shams & Seitz, 2008). Furthermore, integrating congruent motor movements (i.e. motor-enrichment) during acquisition can be superior to only audio-visual acquisition in academically related learning (Mayer et al., 2015). We conducted a six-week cluster-randomized intervention study of motor-enriched mathematics for Danish schoolchildren (n= 148, age= 7.5 ± 0.02). We investigated whether low intensity motor activity congruently integrated during solving of math problems could enhance math performance. Three groups were included: 1) Control group with normal math teaching, CON (used pencil, paper but refrained from additional motor activity). 2) Fine-motor-enriched-group, FM (motor-manipulating LEGO bricks integrated in the lessons). 3) Gross-motor-enriched-group, GM (full-body movements integrated in the lessons). In FM and GM, all math classes (six lessons pr. week) had motor activity integrated in the math lessons and the teachers of all groups followed a detailed description for the conduction of the lessons. This aimed at ensuring homogeneity between groups concerning the taught themes. The children were tested pre- (T0) and post- (T1) intervention. We used a standardized 1st grade math test including 2nd grade questions to avoid a potential ceiling effect. Additionally, we conducted a phonological- and spatial working memory test and a test of executive functioning to investigate potential mediators of academic performance. Furthermore, electroencephalography (EEG) was measured during mental arithmetic at T1. All groups improved from T0 to T1. Interestingly, the improvement in GM from T0-T1 was significantly larger than FM 1.76 ± 0.70 (P = 0.03). Additionally, a subgroup analysis was performed, extracting data from children with learning difficulties, according to national standards (n= 44). In this subgroup no significant differences was observed in the improvements f

Purpose: The current literature is concentrated around the positive effects of aerobic fitness (AF) on performance in cognitive tests (CP) and academic performance (AP) (reviewed in Hillman 2008). However, motor skills (MS) are often overlooked in this equation, and studies evaluating both AF and MS and their relationship to CP and AP are presently lacking. Thus, the purpose of this baseline-association study was to investigate the relationship between MS, AF, CP and AP in children. Method: 166 1st grade children (72 girls, mean age 7.5 years +/-0.31) from the Copenhagen area had their AF, phonological working-memory capacity (PWM), spatial working-memory capacity (SWM), math performance (MP) and fine- and gross-motor skill (FMS & GMS) assessed. Results: Significant associations were found between FMS and MP (P < 0.003), FMS and SWM (P < 0.001) and FMS and PWM (P < 0.001). Likewise, a significant association was evident between GMS and MP (P < 0.001), and GMS and SWM (P < 0.001). Furthermore, significant associations were found between AF and SWM (P < 0.001) and AF and PWM (P < 0.001). Conclusion: We found significant associations between the children´s FMS, GMS, MP and CP. Further studies are needed to investigate possible causal mechanisms underlying the relations between these measures.

High intensity aerobic exercise amplifies offline gains in procedural memory acquired during motor practice. This effect seems to be evident when exercise is placed immediately after acquisition, during the first stages of memory consolidation, but the importance of temporal proximity of the exercise bout used to stimulate improvements in procedural memory is unknown. The effects of three different temporal placements of high intensity exercise were investigated following visuomotor skill acquisition on the retention of motor memory in 48 young (24.0 ± 2.5 yrs), healthy male subjects randomly assigned to one of four groups either performing a high intensity (90% Maximal Power Output) exercise bout at 20 min (EX90), 1 h (EX90+1), 2 h (EX90+2) after acquisition or rested (CON). Retention tests were performed at 1 d (R1) and 7 d (R7). At R1 changes in performance scores after acquisition were greater for EX90 than CON (p < 0.001) and EX90+2 (p = 0.001). At R7 changes in performance scores for EX90, EX90+1, and EX90+2 were higher than CON (p < 0.001, p = 0.008, and p = 0.008, resp.). Changes for EX90 at R7 were greater than EX90+2 (p = 0.049). Exercise-induced improvements in procedural memory diminish as the temporal proximity of exercise from acquisition is increased. Timing of exercise following motor practice is important for motor memory consolidation.
