Abstract Background Despite a growing body of research investigating high-intensity interval training (HIIT) in schools, there are limited process evaluations their implementation. This is concerning because important for appropriately interpreting outcome findings and augmenting intervention design. manuscript presents evaluation Making HIIT , school-based intervention. Methods The spanned 8 weeks was completed at three schools Greater Brisbane, Australia. Ten classes (intervention group) 10-min teacher-led workouts the beginning health physical education (HPE) lessons, five (control continued with regular HPE lessons. mixed methods guided by Framework Effective Implementation Durlak DuPre. Results Program reach : were contacted to successfully recruit from which 79% eligible students ( n = 308, $$\overline{{\text{x}} }$$ x ¯ age: 13.0 ± 0.6 years, 148 girls) provided consent.

Concurrent Effects of Plyometric Interval Training Implemented in Physical Education Lessons on Adolescent Power and Endurance: An Analysis of Responder Prevalence

Sports, Год журнала: 2025, Номер 13(1), С. 15 - 15

Опубликована: Янв. 9, 2025

Schools provide an ideal setting for enhancing adolescents' health and fitness. Short-term intensive interventions are particularly relevant, but the effectiveness of plyometric exercises in jointly improving aerobic anaerobic performance remains uncertain. This study aimed to evaluate effects plyometric-based training, form interval workouts during physical education lessons, on power endurance adolescents. A total 87 boys 95 girls (aged 14-15 years) participated 8-week intervention, performing twice weekly classes. The analyzed parameters were jump height (JH) measured by countermovement (CMJ) distance covered multistage fitness test (MFT). results showed significant improvements among participating JH experiment MFT (p < 0.05); thus, effect sizes relatively small (ES 0.3). Also, prevalence positive responders was more common than girls; however, difference statistically insignificant = 0.09). These findings suggest that training has potential fitness, even context developing opposing abilities, boys. However, varied across individuals generally small, highlighting need optimize intervention achieve pronounced tailored individual characteristics.

Purpose Repeated sprint exercises (RSEs) are widely used to improve physical fitness; however, their specific effects on cardiac autonomic recovery (CAR) in individuals of different ages and biological maturation (BM) stages still lack investigation. Our objective was analyse the effect RSE CAR, assessed by heart rate (HR) index time frequency domains variability (HRV) male adolescents adults. Methods Non-randomised experimental study. Thirty-eight classified as having a high level activity (males, 22 adolescents/16 adults) underwent single session consisting 3 rounds with 6 supra-maximal sprints interspersed 5 minutes passive rest. The HR (between rounds) HRV from pre-, 20 minutes, 2 hours, 24 hours post-RSE were using short-range radio telemetry calculate CAR. In adolescents, BM analysed peak-height-velocity (PHV). Results Adolescents demonstrated more efficient parasympathetic reactivation than adults after (η²_p = 0.574, <i>p</i> < 0.05), especially those pre-PHV stage ( η²_p 0.659, 0.05). For HRV, we identified an for both groups mean square root successive differences intervals between heartbeats (RMSSD) 0.280, 0.05) low frequency/high ratio (LF/HF) 0.129, indicated higher values RMSSD LF. Conclusions Parasympathetic is less affected pre-PHV, RSE. groups, at least two RSE, tended return baseline values, stabilising again

The polar verity sense (PVS) is a user-friendly heart rate monitoring tool for field-based research compared to Polar H10. However, its validity in the real world (e.g., school settings) among children and adolescents yet be determined. Thirty-nine (12.2 ± 0.4 years, 25 males) participated 6-min resistance-based high-intensity interval training (HIIT) session. Heart was simultaneously measured by PVS H10 (criterion measure). Validation metrics included within-participant correlation, mean absolute error, percentage error Bland-Altman plots. Overall, showed very strong correlation (r = 0.93, p < .001) with 4 b·min-1 2.8%, respectively. between decreased 0.84, data above HIIT intensity threshold (≥80% maximal rate) but maintained relationship. of remained similar when accounting sex, body mass index, waist circumference or cardiorespiratory fitness. demonstrated agreement during within setting. Therefore, it valid replace traditional inconvenient chest strap monitors practical ergonomic armband PVS, which could largely enhance feasibility fidelity monitoring.

A much-cited model by Stodden and colleagues has proposed motor competence to be a 17 promising target for intervention increase childhood physical activity. Motor is thought influence future activity through bidirectional causal effects that are partly direct, mediated perceived fitness.

Frontiers in Physiology, Год журнала: 2024, Номер 15

Опубликована: Март 6, 2024

Background: During the past two decades, research on high-intensity interval exercise (HIIE) in children and adolescents has steadily accumulated, especially subthemes of improving cardiometabolic cardiovascular health. However, there is still little scientific understanding using scientometric analysis to establish knowledge maps. Exploring relationship between known new emerging ideas their potential value theoretical practical implications context a researcher’s limited ability read, analyze, synthesize all published works. Objective: First, this study aims provide extensive information HIIE adolescents, including authors, institutions, countries, journals, references. Second, objective use co-occurrence, burst, co-citation analyses based hybrid node types reveal hotspots forecast frontiers for adolescents. Methods: Using bibliographic data Web Science Core Collection (WoSCC) as source, publications, journals were analyzed with help bibliometric methods visualization tools such CiteSpace, VOSviewer, Pajek, Bibliometrix R package. Authorial, institutional, national collaboration networks plotted, along keyword bursts document co-citations. Results: This found that executive function, training, heart rate variability, insulin resistance are topics; mental health, intensity, risk factors continual frontier areas subthemes. Conclusion: Our three novel contributions. it explicitly directly reflects history current situation intervention strategy approach makes clear easy trace origin development specific groups analyzes field predicts trends, which will researchers get deeper pediatric health research. Third, findings enable pinpoint most influential scholars, references field, increasing possibility future collaborations countries.
