ABSTRACT Introduction High-intensity interval training (HIIT) is an effective strategy for improving a variety of health and fitness outcomes within the school settings. Incorporating HIIT into existing physical activity opportunities appears practically feasible, yet process evaluation effectiveness this needs to be further evaluated. Therefore, PRO-HIIT intervention will conducted evaluate 12-week school-based on cardiorespiratory fitness, activity, body composition, muscular strength, bone health, cognitive function, wellbeing academic performance among 12-13-year-olds. Methods analysis Eight classes year 7 students (12-13-year-olds) from secondary in Ningbo, China, recruited randomly allocated or control group. While group maintains their usual activities, 6 10-minute session embedded education lessons five days week 12 weeks Training workshops participants, teachers, research staff facilitating intervention. Outcome data collected at three time points: pre- post-intervention, two months (summer holiday) upon completion Linear mixed models used analyse impact groups (intervention control), timepoints (pre-, post- two-month after intervention) by interactions. The implementation evaluated with guidance MRC framework. Ethics dissemination approval obtained Ningbo University Committee (TY2024002) Public Health Sport Sciences ethics committee, Exeter (5713479). Results PRO- study disseminated via peer-reviewed journals, scientific conferences as well local system. protocol has been retrospectively registered ClinicalTrials.gov Protocol Registration System ( NCT06374732 ), https://clinicaltrials.gov/study/NCT06374732 .

Heart rate (HR) monitoring during exercise represents a potentially useful strategy for teachers delivering physical education lessons. This study examined how projecting HR monitor data onto screen acutely affected school students’ intensity high-intensity interval training (HIIT) session. Twenty students (12.3 ± 0.9 years, male = 8, female 12) from one primary volunteered to participate. Using randomised crossover design within 4-week period, participants completed four sessions of HIIT with projection and no ability view HR. During the condition all viewed their on class in real-time, changing colour according level. Target was 90% age-predicted maximum Peak time above (RED) were collected sessions. Student focus groups teacher interviews conducted gain perceptions around effects projection. ( p 0.005, η 2 effect size 0.049) RED 0.000, 0.083) significantly greater projected condition. Qualitative indicated that improved student motivation reach target, ignited competition amongst peers work harder. Projecting can increase acute HIIT. therefore delivery an emphasis intensity, classes.

Effects of 10 Weeks of Walking With Mobile Step-Tracking Apps on Body Composition, Fitness, and Psychological State in Adolescents Who Are Overweight and Obese: Randomized Controlled Trial

Journal of Medical Internet Research, Год журнала: 2024, Номер 26, С. e55243 - e55243

Background In recent decades, physical activity intervention programs have been developed to reduce overweight and obesity in adolescents. However, this population is considered hard reach due lack of adherence poor results. Interventions with mobile phones the adolescent normal weight shown benefits, so line research may provide benefits adolescents or obesity, although it has not yet explored scientific literature. Objective This study aims determine changes produced by a 10-week promoted during school lessons on education using step tracker apps out-of-school hours activity, Mediterranean diet, body composition, condition who are obese, analyze achieved psychological state obese. Methods The was based randomized controlled trial an initial sample 50 aged between 12 16 years (from first fourth compulsory secondary education), whose level, condition, were measured. Participants divided into experimental group (EG) control (CG), where EG performed series walking steps app their free time outside classes. Adolescents CG continued perform activities as but did use any apps. Inclusion randomized, researchers blinded. Results An increase found corrected arm girth (mean difference –0.46; P=.05), curl-up repetitions –6.35; P=.02) push-up –2.27; P=.04) after intervention. CG, there significant hip –1.37; thigh –1.28; P=.04), muscle mass –0.87; well decrease competence 3.08; P=.03). covariates gender age showed effect (gender: EG; while affected diet P=.04 age: P=.047) relatedness P=.05 P=.04). No differences when comparing EG. Conclusions A program obese for does appear effective producing improvements fitness, adequate significantly activity.
