Food intake and appetite following school-based high-intensity interval training in 9–11-year-old children

Using a randomised cross-over design, free-living lunch intake and subjective appetite were examined in 10 children (9.8 ± 0.6 years) following high-intensity interval training (HIIT) versus a control sedentary (SED) period, within a school setting. The 22-min HIIT took place during a regular PE lesson and consisted of two rounds of 4 × 30 s sprints. Foods were offered at a regular school lunch immediately following HIIT and SED and were matched between conditions. All food was covertly weighed before and after the meal. Hunger, fullness and prospective consumption were reported immediately before and after HIIT/SED, using visual analogue scales. Heart rate was higher during HIIT than SED (159.3 ± 23.1 vs. 76.9 ± 2.2 bpm, P < 0.05). Lunch energy intake was not different (P = 0.52) following HIIT, compared to SED (2.06 ± 0.35 vs. 2.09 ± 0.29 MJ, respectively). There were no significant differences in macronutrient intake or subjective appetite (P > 0.05). Results suggest that HIIT can be implemented in a PE lesson immediately before lunch, without causing a compensatory increase in food consumption.     

The Impact of Gatekeeper Training for Suicide Prevention on University Resident Assistants

Resident assistants (RAs) can serve as important suicide prevention gatekeepers. The purpose of the study was to determine if training improved RAs’ crisis communications skills and suicide‐related knowledge and to determine if the knowledge elements predicted crisis communications skills. New RAs showed significant improvement in all areas from pretest to posttest, whereas returning RAs showed no significant increase in any of the areas. None of the knowledge areas predicted communications skills for either group.

Callous–unemotional (CU) traits in adolescent boys and response to teacher reward and discipline strategies

The aim of this study was to investigate the relationship between callous–unemotional (CU) traits and response to rewards and discipline in adolescent boys using a mixed-methods approach. Participants comprised 39 boys aged between 12 and 13 years and 8 teachers. Quantitative findings showed that CU traits were significantly related to punishment insensitivity, controlling for conduct problems, autism symptoms and hyperactivity. In contrast, there was no significant association between CU traits and reward sensitivity. Qualitative analysis indicated that teachers view children high in CU traits as responsive to fewer reward and discipline strategies, and strategies need to be implemented and monitored with care to avoid unintended, undesirable outcomes. However, time out, praise, support from other staff and maintaining a positive teacher–child relationship were identified as effective strategies. Findings emphasise the need to carefully select, modify and implement existing evidence-based classroom behaviour-management strategies with high-CU children.
