Abstract
Purpose
Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental condition with community prevalence globally of 2%–7% (M = 5%; Sayal et al., 2018). Clinicians are routinely encouraged to explain to children and young people the benefits of a healthy lifestyle, including exercise (NICE NG87, 2018). Exercise has been proposed as a safe and low-cost adjunctive approach for ADHD and is reported to be accompanied by positive effects on several aspects of executive functioning (EF). The purpose of this narrative review was to synthesise the contemporary randomised control trial (RCT) studies that examine the effect of sport, physical activity and movement on EF in children and adolescents with ADHD.
Design/methodology/approach
A narrative review approach with a systematic literature search using PRISMA guidelines for screening and selecting relevant systematic reviews was used. The final review included four peer-review systematic reviews (>2019).
Findings
The results identified four RCT meta-analyses and findings showed that children and adolescents with lower baseline cognitive performance demonstrated greater improvements in functioning after physical activity interventions, particularly for tasks with higher executive function demands, where baseline performance reaches an optimal level. Findings suggest that 10–20 min of acute moderate-high-intensity exercise interventions (cycling/running) appeared to have positive effects on indices of inhibitory control. Preliminary evidence suggests that as little as 5 min of jumping exercises improved inhibitory control. Sixty to eighty minutes of moderately intense, repeated (chronic) exercise appeared to demonstrate the greatest beneficial impact on selective attention.
Originality/value
To the best of the authors’ knowledge, this review is the first to present the extant literature on the effect of physical activity and sport on symptoms of young people with ADHD. It presents evidence to suggest that exercise with progressively increasing cognitive demands may have positive effects for children with ADHD, specifically in terms of improving cognitive flexibility. Further large-scale clinical trials are needed to confirm the positive effects of physical exercise on cognitive functioning in children with ADHD.

Abstract
Purpose
The innovation process demands an interaction between environment agents, knowledge generators and policies of incentive for innovation and not only development by companies. Universities have gradually become the core of the knowledge production system and, therefore, their role regarding innovation has become more important and diversified. This study is aimed at identifying the mechanisms of university–industry (U–I) collaboration, as well as the operationalization steps of the U–I collaboration process.
Design/methodology/approach
This study is aimed at identifying, based on a systematic literature review, the mechanisms of university–industry (U–I) collaboration, as well as the operationalization steps of the U–I collaboration process.
Findings
The analysis of the 72 selected articles enabled identifying 15 mechanisms of U–I collaboration, proposing a new classification for such mechanisms and developing a framework presenting the operationalization steps of the interaction process.
Originality/value
In this paper, the authors screened nearly 1,500 papers and analyzed in detail 86 papers addressing U–I collaboration, mechanisms of U–I collaboration and operationalization steps of the U–I collaboration process. This paper provides a new classification for such mechanisms and developing a framework presenting the operationalization steps of the interaction process. This research contributes to both theory and practice by highlighting managerial aspects and stimulating academic research on such timely topic.
