Effects of Physical Activity on Cognition, Behavior, and Motor Skills in Youth with Autism Spectrum Disorder: A Systematic Review of Intervention Studies

The aim of this paper was to analyze the acute and chronic effects of physical activity (PA) on cognition, behavior, and motor skill in youth with autism spectrum disorder (ASD), taking into account potential confounders. In addition, it was intended to elaborate a guide of educational applications with strategies for PA use. Studies were identified in four databases from January 2010 to June 2023. A total of 19 interventional studies met the inclusion criteria. PA programs ranged from two weeks to one year in duration, with a frequency of one to five sessions per week. More than 58% of the studies showed positive effects of PA on cognition, and 45.5% on behavior and motor skill. Moderate-vigorous PA for 15-30 min has shown acute effects on cognition, general behavior, and stereotypic/repetitive behaviors in youth with ASD. A total of 9 out of 14 studies showed chronic effects on general behavior and stereotypic behaviors, and only 6 on motor skills.

Effect of an Integrated Active Lessons Programme through Playful Maths Games on Self-Concept, Self-Esteem and Social Skills in Preschool Children

The aim of this study was to analyse the effects of an integrated active lessons programme based on playful math games, of 10 weeks’ duration (30 min/day × 2 days/week), on self-concept, self-esteem and social skills in preschool children. One hundred and ninety-four preschool children (53.6% girls) aged 53.36 ± 11.82 months were split into a control group (CG) and an experimental group (EG). The EG improved significantly in self-concept compared to the CG in boys and girls (6.8% and 7.1%, respectively). Personal and academic self-esteem levels increased significantly (8.1% and 5.5%, respectively, only in girls). Although the EG obtained significant improvements in social self-esteem and social skills compared to the beginning of the study, these results were not found in comparison with the CG. The introduction of active lessons based on playful maths games within the classroom is recommended as support for the improvement in self-concept, self-esteem and social skills in early childhood education.

Active commuting to school among 36,781 Spanish children and adolescents: A temporal trend study

This study examines trends in the rates of active commuting to school (ACS) in Spanish children (n = 18 343; 8.93 ± 1.68) and adolescents (n = 18 438; 14.11 ± 1.58) aged 6-18 years from 2010 to 2017. Given the study period included the economic crisis in Spain (2008-2013), the second aim of this study was to compare ACS rates during and after the economic crisis. Data were obtained from 28 studies conducted across Spain. The overall trends in ACS were evaluated using multilevel logistic regression analysis. Among Spanish children and adolescents, the rates of ACS to school ranged around 60% between 2010 and 2017. The rates of ACS in Spanish youth did not change significantly during the 2010-2017 period, except a sporadic increase in the rate of ACS in adolescents in 2012-2013. No significant association between the ACS and the economic crisis time period in youth was found. As conclusion, the ACS remains stable in Spain during the last decade, which is a promising result regarding the evidenced decreasing trend in many countries. Further educational and policy strategies are important to continue promoting this behavior in children and adolescents in the long term.

Perceived physical fitness mediates the relationship between parental support and physical activity enjoyment in overweight and obese adolescents

The relationship between parental support and physical activity enjoyment appears to be mediated by individual-level factors. The aim of this study was to examine whether the relationship between perceived parental support and physical activity enjoyment is mediated by overweight and obese adolescents' physical fitness, both subjectively and objectively assessed. A total of 163 participants (mean age =14.30 years, 55.8% boys) with an average body mass index of 28.97 kg/m2 took part in this study. Participants completed a questionnaire of parental influence regarding physical activity, a questionnaire of physical self-perception and several fitness tests (cardiorespiratory fitness, lower limbs muscular strength and flexibility) using the ALPHA-fitness battery. The results showed that relationship between perceived parental support and physical activity enjoyment is mediated by the overweight and obese adolescents' perceived cardiorespiratory fitness and flexibility. We suggest to create educational guidelines for parents to increase the support and improve overweight and obese students' positive perceived physical competence, in order to achieve a greater adherence to physical activity and greater physical activity enjoyment.

Sports participation for mental health promotion among socially vulnerable youth: a study protocol

The benefits of participation in organized sports on mental well-being of young people are well-known. However, there is lacking evidence on the relationship between participation in organized sports and positive mental health among socially vulnerable young people. Also, little is known about the mechanisms of sports-based programmes that may promote positive mental health among socially vulnerable young people.

The aim of this PhD study is to investigate the association between participation in organized sports and positive mental health among socially vulnerable children (7-12 years) and adolescents (13-15 years) using multiple methods and several databases.

I will present the study protocol of a PhD study focusing on use of sports participation as a tool for mental health promotion. Article 1 will be a systematic literature review and the data will be gathered from multiple databases. Article 2 is based on the School Health Promotion Study carried out in 2017 (ages 14-15; n = 73 680). Article 3 is based on Icehearts longitudinal study (n = 46 children participating Icehearts programme and n = 180 controls) and article 4 is based on observations (n = 5 Icehearts teams including 50 children and 5 coaches) and interviews (25 Iceheartś children and their 50 parents).

Preliminary findings of the systematic literature review indicate that there is a lack of evidence how to promote mental well-being through sports participation among socially vulnerable young people.

The study will provide valuable knowledge which can be utilized to prevent mental health problems and to promote positive mental health. This knowledge can be used both in municipal and political decision-making, and in developing targeted, sport-based interventions for socially vulnerable children and adolescents in order to reduce health inequalities.

Key messages

Observational data on interventions including perspectives of children is rare but crucial to develop effective programmes for promoting positive mental health among socially vulnerable youth. Knowledge obtained from this study can be used to develop targeted, sport-based interventions for socially vulnerable children and adolescents in order to reduce health inequalities.

Apoyo social y práctica de actividad física en adolescentes: Análisis del efecto mediador de la autoeficacia y obstáculos percibidos para su práctica

El apoyo parental que los hijos perciben en sus progenitores se ha relacionado con la frecuencia e intensidad de práctica de actividad física de niños y adolescentes. Recientemente, los modelos socio-ecológicos sostienen que estas influencias familiares pueden incidir de forma tanto directa como indirecta, por medio de factores intrapersonales, en este comportamiento saludable. En este estudio un total de 570 estudiantes (52.63% chicas) de Educación Secundaria Obligatoria, con un promedio de 13.96 años (DT= 1.36), aportaron información del apoyo instrumental, modelado y restricción al comportamiento sedentario atribuido a madres y padres, la autoeficacia y obstáculos percibidos para la práctica de actividad física, así como de la frecuencia semanal con la que realizaban actividad física a una intensidad que oscilaba entre moderada y vigorosa. Los resultados mostraron que el apoyo parental atribuido en sus distintas formas mantuvo relaciones positivas con la actividad física autoinformada. Adicionalmente, la autoeficacia actuó como una variable mediadora en la relación entre apoyo percibido y práctica de actividad física, mientras que las barreras que dificultan su realización no. Estos hallazgos apuntan la necesidad de considerar diferentes mediadores de naturaleza personal a la hora de conocer cómo la percepción de ciertas actuaciones parentales condiciona la práctica de actividad física, tanto dentro como fuera del contexto escolar, de los adolescentes.

48-Hour Effects of Monitored Cooperative High-Intensity Interval Training on Adolescent Cognitive Functioning

Physical activity has been positively related to better cognitive performance though the effects of varied exercise type and intensity and the duration of cognitive benefits are unclear. This study analyzed the effect of 16 minutes of monitored cooperative high-intensity interval training (monitored C-HIIT) at the start of the school day, on various cognitive variables over the next 24-48 hours. We randomly assigned 158 participants either to a control group ( n = 81) that engaged only in static stretching or to an experimental group ( n = 77) that performed monitored C-HIIT. We assessed cognitive functioning before the exercise, immediately afterward, and for five follow-up time points over the next two days (i.e., at 2, 3, 4, 24, and 48 hours). We analyzed age, sex, body mass index, and moderate-to-vigorous physical activity as potential confounder variables. Adolescents in the monitored C-HIIT group increased selective attention by 17.39% during the next hour ( p = .015) and increased concentration by 20.31% and 15.26% during the first ( p = .022) and second ( p = .059) subsequent hours, respectively. This positive short-term benefit of monitored C-HIIT during immediate subsequent hours is an important finding with implications for the school curricula and schedule.

Acute and chronic effect of physical activity on cognition and behaviour in young people with ADHD: A systematic review of intervention studies

BACKGROUND

Young people with attention deficit hyperactivity disorder (ADHD) often have learning and behavioral control difficulties.

AIM

The aim of this review is analyse the acute and chronic effect of physical activity (PA) on the cognition and behaviour of children and adolescents with ADHD.

METHODS

Studies were identified in five databases (PubMed, SPORTDiscus, ProQuest, Web of Science, and SCOPUS), from January 2000 through to January 2017. A total of 16 interventional studies met the inclusion criteria.

RESULTS/CONCLUSIONS

PA practice of 20-30 min (intensity 40-75%) produces a positive acute effect on processing speed, working memory, planning and problem solving in young people with ADHD. However, these effects on behaviour are contradictory and vary depending on age. Chronic PA practice (≥30 min per day, ≥40% intensity, ≥three days per week, ≥five weeks) further improves attention, inhibition, emotional control, behaviour and motor control. The results must be treated with caution, because only 25% of the studies used confounders.

IMPLICATION

More research is needed to justify the causes of these effects. It is necessary to establish programs with regard to the duration, intensity, kind of exercise, and time of PA to improve cognition and behaviour in young people with ADHD taking into account potential confounders.

Comparison of the inflammatory and stress response between sprint interval swimming and running

The aim of the study was to compare myocellular damage, metabolic stress, and inflammatory responses as well as circulating sodium (Na⁺ ) and potassium (K⁺ ) between a single sprint swimming and running training. Eighteen subjects regularly involved in swimming and running training for at least 2 years were recruited. The subjects performed 8 × 30 seconds "all out" exercise on different days either by running or by swimming in a random order. Blood was collected before each training session, after the cessation of exercise (post) and after 2 hours of rest (2 hours). We then analyzed tumor necrosis factor alpha (TNF-α), interleukin 10 (IL-10), interleukin 6 (IL-6), cortisol, creatine kinase MB isoform (CK-MB), lactate dehydrogenase (LDH), K⁺ , and Na⁺ . Neither TNF-α nor IL-10 differed between swimming and running. Most of the subjects showed a non-statistically significant increase of LDH and CK-MB after swimming. On the other hand, IL-6 (P < .05) and cortisol (P < .05) were significantly lower after 2 hours of swimming than after running. In addition, post-exercise K⁺ was significantly lower (P < .001) for swimming than for running. Our results provide evidence of similar inflammatory responses between exercise modes but lower metabolic stress in response to swimming than in response to running.

Perfiles de orientación hacia la meta y su relación con indicadores de actividad físico-deportiva

El presente estudio examinó la motivación hacia la actividad física empleando la teoría de la orientación hacia la meta. Un total de 786 estudiantes participaron en este estudio. Un procedimiento de análisis de cluster jerárquico permitió identificar cuatro perfiles de orientación hacia la meta. El perfil más adaptativo (alta tarea/alto ego/altas expectativas) se asoció con la obtención de los mejores resultados. Se concluye que los jóvenes con una alta motivación hacia la tarea, ego, y expectativas de ejecución obtienen las mayores muestras de apoyo por parte de familiares e iguales para la práctica de actividad física, se perciben más autoeficaces para realizar dicha actividad, se atribuyen una mejor forma física autopercibida, y manifiestan una práctica más frecuente de actividad físico-deportiva.

Effects of a steps/day programme with evaluation in physical education on body mass index in schoolchildren 11-12 years of age

The aim of the study was to assess the effects that a steps/day programme may have on body mass index (BMI) among primary education students (11.37±0.48 years). A six-week controlled trial with a follow-up was completed with an experimental group (N=66, pedometer + steps/day programme + reinforcement programme in their physical education (PE) marks + weekly follow-up in PE), and a control group (N=76). Omron HJ-152-E2 pedometers were used. Normoweight students complied with programme requirements to a greater extent than their overweight counterparts (72.7 vs 59.1%). The programmed minimum number of 12,000 steps/day for boys and 10,000 for girls was exceeded by 83% of boys and 60% of girls. The differences in the number of steps/day between boys (14,274) and girls (10,626) were significant across all the measured periods (p&lt;.05). The results show that the teenagers who complied with the programme requirements reduced their BMI significantly after the intervention (p&lt;.001) and this reduction persisted for six weeks after the programme (p&lt;.001). In conclusion, the six-week programme of 12,000 steps/day for boys and 10,000 for girls, jointly with a reinforcement programme in their PE marks and weekly follow-up by their PE teacher, reduces BMI significantly in 11-12-year-old schoolchildren. Monitored steps/day programmes in the PE curriculum increase out-of-school physical activity and reduce BMI in 11-12-year-old schoolchildren.

Impact of limited hamstring flexibility on vertical jump, kicking speed, sprint, and agility in young football players

This study aims to analyse the impact of limited hamstring flexibility (HF) on specific football skills, such as sprinting and jumping ability, agility, and kicking speed in young football players. Forty-three male football players (aged 14-18) from a semi-professional football academy participated voluntarily in this study. Data about anthropometric measurements, HF (unilateral passive straight-leg raise test: PSLR), vertical jumping ability (countermovement jump: CMJ), sprinting ability (5, 10, 20 m: S5 m, S10 m, S20 m), agility (Balsom agility test: BAT), and kicking speed in terms of ball speed (dominant and non-dominant leg: KSdom and KSnon-dom) were collected. Cluster analysis grouped according to HF, dividing participants into a flexible group (FG, n = 24) and a non-flexible group (NFG, n = 19) in relation to performances on the PSLR test. Despite finding no significant differences between groups in body composition and age, the FG performed better in terms of sprint scores (S5 m: 6.12%, S10 m: 4.09%, S20 m: 3.29%), BAT score (4.11%), CMJ score (10.49%), and scores for KSdom (6.86%) and KSnon-dom (8%) than the NFG. The results suggest that HF is a key factor for performing football-specific skills, such as sprinting, jumping, agility, and kicking in young football players. These results support the rationale that muscle flexibility must be specifically trained in football players beginning at early ages.
