Summary: The systematic review found that conversational agents have moderate usability and feasibility in promoting physical activity, and those evaluated through randomized controlled trials were effective. Common challenges included repetitive program content, high attrition, technical issues, and safety and privacy concerns. Reasearch lacks on long-term intervention effectiveness and patient safety, suggesting future interventions should address these issues.

Summary: This systematic review and meta-analysis examined the effectiveness of gamified interventions in promoting physical activity. The results showed that gamified interventions have a positive effect on physical activity and can be applied to different populations. When compared with inactive control groups and nongamified physical activity interventions, gamified interventions were found to be more effective. However, the long-term effect was weaker.

Summary: Previous research on using mobile applications to increase physical activity and improve health among adolescents lacks conclusive results due to low adherence after the first weeks. This study aimed to determine the changes brought by a compulsory ten-week after-school intervention with mobile step-tracking applications on adolescents' health, and to compare the benefits of each application. A longitudinal study with non-probability convenience sampling was conducted, involving 400 adolescents from two public secondary schools in Murcia, Spain. The results showed that the experimental group had higher physical activity levels, better body composition, and physical fitness variables compared to the control group, with variations between the different applications used. In conclusion, this research highlights the usefulness of mandatory after-school use of mobile applications for improving adolescent health and addresses the need for sufficient physical education teaching hours.

Summary: The relationship between weight stigma and physical activity is complex, with most studies finding that everyday weight discrimination and internalization are associated with reduced physical activity, and weight-based teasing in youth is also linked to reduced physical activity. The associations are inconsistent and often indirect, suggesting the need for further investigation in future research with larger samples and longitudinal assessments.

Summary: This review and meta-analysis examined the effectiveness of mHealth interventions on insufficient physical activity (IPA) and sedentary behavior (SB) among children and adolescents. The study found that mHealth interventions with high levels of individualization can significantly reduce insufficient physical activity levels, particularly in adolescents. However, interventions targeting sedentary behavior or with low levels of individualization did not show a significant overall effect. These findings highlight the importance of individualized interventions in promoting physical activity among young people.

Summary: This qualitative study explored the emotional experiences related to physical activity of post-MBS patients, identifying both positive factors such as enjoyable exercises, social interaction, mindfulness, and mastery, as well as negative factors unique to the MBS population like all-or-nothing thinking, distraction, depression, negative body image, exercising only for weight loss, and the impact of the COVID-19 pandemic. Emotions were found to play a significant role in participants' decision to be physically active and maintain their habits, suggesting that an intervention focusing on positive emotional factors and addressing negative emotional factors could be effective in increasing physical activity after MBS.

Summary: This systematic review and meta-analysis examined the effect of physical activity on weight loss in adults who underwent bariatric surgery. The study also compared biomarkers between individuals with different levels of physical activity after surgery. The results showed that BMI as a measure of physical activity had a positive impact on the target population. However, further larger-scale studies with stricter criteria are needed to confirm these findings.

Summary: Exercise can improve the quality of life for older people, and fitness tracking and social support play important roles in motivating them. This study found that real-time feedback can encourage physical activity among older adults, but engrained routines between older couples may impede behavior change.

Summary: This study conducted a systematic search and content analysis of apps designed to promote physical activity among pregnant women, focusing on app quality, features, and the presence of behavior change techniques (BCTs). The findings showed that while the apps were functional and aesthetically pleasing, the incorporation of BCTs was low, indicating a need for improvement in utilizing techniques that have been effective in promoting physical activity behavior change among pregnant women.

Summary: Research shows that adults with ASD have poor health outcomes, but lack effective health interventions. Mobile health applications show potential for promoting physical activity in adults with ASD, but long-term effectiveness is inconclusive. Behavior change techniques and gamification-guided mobile health applications may be promising strategies for increasing PA in these individuals.

Summary: The study found that users have diverse preferences for implementation types and design characteristics of persuasive strategies in mobile applications aimed at promoting physical activity, such as basic statistics, positive feedback, and motivating reminders. It is important for persuasive strategies in mHealth applications to be designed in a way that aligns with health guidelines and can be personalized based on individual preferences.

Summary: This study explored the experiences of hospital patients who received recommendations for increasing physical activity and engaging in a telephone coaching program during outpatient consultations. Results showed that most patients found the recommendations acceptable and helpful for behavior change. Surgeons played a significant role in promoting contemplation of physical activity change and patients appreciated a communication style that supported autonomy.

Summary: The International Society for Physical Activity and Health emphasizes the importance of increasing the capability of the physical activity workforce as a key component of a system-based approach. Young leader programs are gaining popularity worldwide as peers have a significant influence on young people and positive role models are essential for promoting physical activity. However, there is limited understanding of effective training methods for young physical activity leaders. This study aims to develop a consensus on how to identify and support young people in becoming physical activity leaders.

Summary: This study aims to evaluate the efficacy of a new child-led emotion regulation intervention model, Purrble, in prevention and treatment contexts. The experiment with children aged 8 to 10 will compare the impact of Purrble and an active control (noninteractive plush toy) on child emotion regulation capability. Insights will be gained through weekly questionnaires and postdeployment interviews to further optimize the intervention.

Summary: This study aims to empirically investigate JIT states using system ID methods to optimize a scalable JITAI for physical activity. Physically inactive adults who owned smartphones were recruited, and their steps were monitored using a Fitbit Versa 3 for 270 days. The experiment involved systematically varying the delivery of notifications and suggested daily step goals to study different operationalizations of JIT states. The results of this study are expected to be published in the fourth quarter of 2023.
