Background: Nutritional supplements are widely used by swimmers, but the effectiveness of various supplements and the identification of the most effective intervention require further investigation. Purpose: This paper evaluated and compared the effectiveness of various nutrition-based interventions on swimming performance through both direct and indirect comparisons. Methods: PubMed, Embase, Web of Science, Cochrane Library, and SPORTDiscus databases were thoroughly searched up to 4 April 2024. The risk of bias was judged using the Cochrane risk of bias tool. A random-effect model was adopted to compute standardized mean differences (SMD) and 95% confidence intervals (CI). Results: L-arginine (Arg) demonstrated superior performance to the placebo (SMD = −1.66, 95% CI [−2.92, −0.44]), emerging as the most effective intervention for reducing 100 swimming time (SUCRA = 89.5%). Beta-alanine (BA) was the best intervention for improving blood lactate (SUCRA = 80%). Creatine combined with sodium bicarbonate (Creatine_NaHCO3) significantly increased blood pH compared to the placebo (SMD = 3.79, 95% CI [1.85, 5.80]), with a SUCRA score of 99.9%, suggesting it is the most effective intervention for this parameter. No prominent differences were noted among the interventions in 50 m time, 200 m time, heart rate, and body mass. Conclusions: Dietary supplements might provide benefits for improving swimming performance. Arg emerged as the most efficacious modality for reducing 100 m time. BA proved to be the preeminent strategy for decreasing blood lactate. Creatine_NaHCO3 was distinguished as the optimal approach for improving blood pH. [ABSTRACT FROM AUTHOR]

BACKGROUND: Trolley bags have gained popularity among students, but there is limited research comparing them to backpack-style school bags. OBJECTIVE: This study aimed to compare how carrying a backpack versus a trolley bag affects the activity of trunk and lower limb muscles in secondary school students. METHODS: Electromyographic activity was measured in 25 students (13.4±1.1 years) as they walked on level ground and up/down stairs while carrying both types of bags. The activity of the gastrocnemius, tibialis anterior, semitendinosus, rectus femoris, lumbar erector spinae, and rectus abdominis muscles was assessed on both the dominant and non-dominant sides. RESULTS: The study found significantly reduced muscle activation in most of the targeted muscles when walking on level ground with the trolley bag and when going up/down stairs with the backpack. CONCLUSIONS: Lifting a trolley bag depends on the slope of the walking surface and is more efficient on level ground, while carrying a backpack is more efficient when going up and down stairs. Since it is not practical to switch bags when encountering stairs in schools, a bag with a mixed model design incorporating features of both trolley and backpack may be more beneficial and practical for students to use. Students, parents, and teachers should be aware of the injury risks associated with carrying different types of bags. [ABSTRACT FROM AUTHOR]

Most studies of social robot interventions for children with autism spectrum disorder have been laboratory experiments focusing on component skills. There is insufficient evidence documenting the qualitative impact of such programmes on social development and participation of children with autism spectrum disorder. This study aimed to identify the qualitative outcomes of a robot-mediated social skills training programme for children with autism spectrum disorder, examine the impact of such programmes on children's social participation and identify the essential elements of robotic interventions that are conducive to children's social development. A case study approach with a multiple case study design was adopted. Sixteen children with autism spectrum disorder, aged 5–11 years, were included. Participants received 12 weekly sessions of robot-mediated social skills training. The successful outcomes relating to social participation were identified as enhanced verbal expression, social awareness and emotional reciprocity. The impacts of the programme on personal development were identified as enhanced self-esteem, self-confidence and emotional expression. Robot friendship, the role of the robot as a facilitator and the presence of a human instructor capable of leading the programme were identified as essential elements of the positive changes. The encounter with a social robot was regarded as meaningful and important to the children with autism spectrum disorder. [ABSTRACT FROM AUTHOR]

AbstractPurposeMethodsResultsConclusions\nIMPLICATIONS FOR REHABILITATIONHumanoid robot intervention programmes for children with autism spectrum disorder (ASD) are being developed rapidly. This study aimed to develop and test a robotic intervention framework for children with ASD to ensure best practice.In Phase I of this study, an initial framework was built based on a scoping review. This review aimed to identify the core elements conducive to effective robotic intervention programmes for children with ASD. In Phase II, the content of the initial framework was verified using a case study approach in a real-life setting.The robotic intervention framework, which comprised three domains, was built and tested. The three domains were robot-, child-, and programme-related factors. Elements within each domain were identified and verified in real-life contexts.The proposed framework will enhance evidence-based practice in robotic intervention programmes. However, further clinical testing is warranted to enhance the efficacy and validity of this framework. A good programme design incorporating all essential elements for effective intervention will ensure the success of the training programme for children with ASD.Contribute to the development of knowledge of and theoretical base for using robotic interventions for children with ASD.This study developed a testable program framework and inform researchers about scientific evidence regarding effective use of robotic intervention in the fields of rehabilitation and education.Contribute to the advancement of evidence-based practice (EBP) in the field of autism.Contribute to the development of knowledge of and theoretical base for using robotic interventions for children with ASD.This study developed a testable program framework and inform researchers about scientific evidence regarding effective use of robotic intervention in the fields of rehabilitation and education.Contribute to the advancement of evidence-based practice (EBP) in the field of autism.

Comfort is vital in sportswear design. Previous research focused on the thermo-physiological comfort of modal blended fabric by examining its physical and thermal properties, neglecting comprehensive wear trials. This study compared the perceived comfort of two sportswear samples: polyester fabric and modal blended fabric. Ten participants (mean age = 22.4) wore the samples in random order during two trials. Each trial involved 25 min of treadmill running at a self-selected speed in a laboratory with a room temperature of 23.5 ± 1°C and 50% humidity. Heart rate, blood lactate level, skin temperature, perceived exertion, self-reported comfort, sportswear weight change, and fabric properties were recorded. Results showed that the blended fabric offered superior comfort despite the polyester fabric demonstrating better moisture transfer. This suggests that fabric composition and absorbency contribute to comfort and moisture transmission. Future studies should explore fabric structures and their impact on comfort in modal blended fabric using comprehensive human trials. [ABSTRACT FROM AUTHOR]
