Department of Physiotherapy, Faculty of Health Science, Universitas Muhammadiyah Surakarta , ID2026-08-24|page 220-232AbstractBackground: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. Objective measurement of motor activity may complement parent-reported assessment of ADHD symptoms.
Objectives: This study aimed to examine the association between ADHD Rating Scale-5 scores and step counts, used as an objective indicator of motor activity, among children aged 4–6 years.
Methods: A cross-sectional observational study was conducted among 110 children aged 4–6 years selected through purposive sampling. ADHD symptoms were assessed using the parent-completed ADHD Rating Scale-5, while step counts were measured using a digital pedometer during a 15-minute school recess. Data normality was assessed using the Kolmogorov–Smirnov test. Pearson's product–moment correlation was used to examine the association between total ADHD Rating Scale-5 scores and step counts, whereas Spearman's rank correlation was used for the Inattention and Hyperactivity–Impulsivity domain scores.
Results: Total ADHD Rating Scale-5 scores showed a very strong positive correlation with step counts (r = .865, p < .001). At the domain level, Inattention scores showed a strong positive correlation with step counts (ρ = .756, p < .001), while Hyperactivity–Impulsivity scores showed a very strong positive correlation (ρ = .818, p < .001).
Conclusions: Higher ADHD symptom scores were strongly associated with higher motor activity, as indicated by step counts, among preschool children. Step-count measurement may provide a simple objective measure that complements parent-reported assessment of ADHD symptoms; however, it should not be interpreted as a diagnostic measure for ADHD.

Federal University of Uberlandia - MG, 38405-320, Brazil , BR2024-05-05|page 57-76AbstractBackground: Hypothyroidism reduces circulating levels of thyroid hormones metabolic enzymatic activities, and the skeletal muscle's work capacity and lactatemia increase during exertion.
Objectives: To analyze salivary biomarkers and blood lactate obtained in exercise stages through exhaustion and investigate their correlation.
Methods: Eight females attended the University Clinical Hospital who showed a condition of subclinical hypothyroidism. Before they began replacing with L-thyroxine, they were submitted to an ergometric test to check their tolerance to effort. Eight weeks after treatment, all volunteers were again submitted to lab and ergometric tests. Saliva and blood were collected to determine total protein, nitric oxide, IgA, lactate, and lipid profile.
Results: The present study identified a correlation (0.8), so the behavior of the blood lactate could explain the behavior of the salivary of total proteins by 74.22% (R2 = 0.7422). Lactate production was minimized when women underwent L-thyroxine treatment in the first six stages of exercise. Still, total salivary proteins increased for pharmacotherapy between stages 1 and 8. While salivary nitric oxide had a percentage variation between pre- and post-exercise times of 96% before the start of treatment when the same exercise was performed after eight weeks of treatment with L-Thyroxine, this variation was 150%.
Conclusion: The measurement of STP is an essential marker of stress, and it is highly correlated with the most used blood marker, lactate. Regarding treatment with L-Thyroxine in women with subclinical hypothyroidism, after eight weeks of this therapy, it was possible to observe a reduction in blood lactate production after the incremental load test on a cycle ergometer, accompanied by a reduction in the concentration of SA. SNO and SIgA tended to increase in women undergoing treatment, and this treatment should be considered in subsequent studies as causing a different effect on these markers.

The effect of peer teaching and think pair share on rhythmic gymnastics learning outcomes
Muhammad Lutfi Hasan1, Ibnu Fatkhu Royana2, Utvi Hinda Zhannisa31. Universitas PGRI Semarang , ID2. Universitas PGRI Semarang , ID3. Universitas PGRI Semarang , ID2025-08-14|page 195-203AbstractBackground: Rhythmic gymnastics plays a vital role in developing students' motor skills, coordination, and rhythm, yet many still face challenges in mastering movement concepts.
Objectives: This study compared the effectiveness of Peer Teaching and Think Pair Share (TPS) cooperative learning models in improving rhythmic gymnastics learning outcomes.
Methods: A quasi-experimental design with a two-group pretest–posttest was conducted on 68 eighth-grade students (male and female) at State Junior High School 4 Semarang, divided into Peer Teaching (n=34) and TPS (n=34) groups. Learning outcomes were assessed using a validated rhythmic gymnastics performance test, and data were analyzed descriptively with gain score calculation.
Results: The TPS group achieved a greater improvement in posttest scores (from 67.21 to 79.59; +18.41%) compared to the Peer Teaching group (from 79.18 to 79.85; +0.85%). These results indicate that TPS enhances students' understanding, coordination, and engagement in rhythmic gymnastics learning.
Conclusions: TPS is recommended for physical education teachers to improve performance, particularly for students with lower initial skills. Further studies should explore its long-term effects and retention.
