Evidence suggests that moderate physical activity (PA) positively relates to creativity and emotional intelligence (EI) in adolescents. However, it is unknown whether cooperative PA (physical exercises in pairs or small groups to enhance motivation, self-efficacy, and pro-social behaviours), performed over less time but at higher intensity, could have similar effects within a school setting. The aim was to analyse the effect of cooperative high-intensity interval training (C-HIIT) on creativity and EI in adolescents aged 12–16 years, and whether improvement effects are different according to weekly PA level. A randomised controlled trial was conducted with a control group (CG, n = 94), which did static stretching, and an experimental group (EG, n = 90), which performed C-HIIT. Both groups performed the activity during 16 minutes at the beginning of physical education (PE) classes. Creativity was assessed with one factor, and EI through four factors (well-being, self-control, emotionality, and sociability). Age and body mass index (BMI) were used as confounders. Both were measured twice (baseline and after 12 weeks). The EG increased well-being and sociability factors after the C-HIIT programme (both p < 0.001). More specifically, inactive adolescents in the EG showed significant improvements in comparison to the CG in creativity, well-being, and sociability ( p = 0.028, p < 0.001, and p < 0.003, respectively). However, we did not find changes among active adolescents. A programme of C-HIIT in PE is a novel strategy to improve creativity and EI, especially in physically inactive adolescents. Starting PE classes with 16 minutes of C-HIIT could be recommended, independently of other activities planned for the session.

In the present randomised-controlled trial we investigated the effect of reduced-exertion high-intensity interval training (REHIT) training frequency (2, 3, or 4 sessions/week for 6 weeks) on maximal aerobic capacity in 42 inactive individuals (13 women; mean ± SD age: 25 ± 5 years, maximal aerobic capacity: 35 ± 5 mL·kg−1·min−1). Changes in maximal aerobic capacity were not significantly different between the 3 groups (2 sessions/week: +10.2%; 3 sessions/week: +8.1%; 4 sessions per week: +7.3%). In conclusion, a training frequency of 2 sessions/week is sufficient for REHIT to improve maximal aerobic capacity. Novelty We demonstrate that reducing REHIT training frequency from 3 or 4 to 2 sessions/week does not attenuate improvements in the key health marker of maximal aerobic capacity.

ObjectiveTo compare effects of moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) on platelet function in patients undergoing cardiac rehabilitation, as hyper-reactive platelets are involved in atherogenesis and atherothrombosis.MethodsIn this single-centre parallel group randomised controlled trial, male patients after an acute coronary syndrome under dual antiplatelet therapy performed MICT or HIIT+MICT for 12 weeks. Main outcome was platelet reactivity measured by the half-maximal concentration (EC50) of platelet agonist thrombin receptor-activating peptide-6 (TRAP-6) in terms of P-selectin expression. EC50 was determined at baseline, after 6 and 12 weeks, each time at physical rest and on exertion.Results82 patients were randomised to MICT or HIIT+MICT. Mean (95% CI) baseline EC50values at physical rest were 6.7 µM (6.3 µM to 7.0 µM) TRAP-6. After 6/12 weeks, 36/33 MICT and 34/28 HIIT+MICT patients were examined. HIIT+MICT patients had 0.9 µM (0.4 µM to 1.4 µM)/0.5 µM (−0.1 µM to 1.0 µM) higher EC50values than MICT ones, and the propensity of their platelets to form aggregates with monocytes was significantly lower after 12 weeks. Short-term strenuous physical exertion was generally associated with platelet activation and an EC50reduction of 0.7 µM (0.6 µM to 0.8 µM). HIIT+MICT patients tended to be fitter after 12 weeks. No serious harms were observed.ConclusionsIncluding HIIT in cardiac rehabilitation seems to confer additional benefits compared with MICT alone, which should be confirmed in clinical trials with hard endpoints. Exertion-induced platelet activation and hyper-reactivity occur despite dual antiplatelet therapy.Trial registration numberNCT02930330; Results.
