Article Abstract
This study examined the combined effects of breakfast and exercise on short-term academic and cognitive performance in adolescents. Eighty-two adolescents (64 female), aged 14-19 years, were randomized to four groups over a 4-hour morning: (i) a group who fasted and were sedentary (F-S); (ii) a group who ate breakfast but were sedentary (B-S); (iii) a group who fasted but completed a 30-min exercise bout (F-E); and (iv) a group who ate breakfast and completed a 30-min exercise bout (B-E). Individuals completed academic and cognitive tests over the morning. Adolescents in B-E significantly improved their mathematics score (B-E: 15.2% improvement on correct answers, vs. F-S: 6.7% improvement on correct answers; = 0.014) and computation time for correct answers (B-E: 16.7% improvement, vs. F-S: 7.4% improvement; = 0.004) over the morning compared with the F-S group. The B-E group had faster reaction times for congruent, incongruent and control trials of the Stroop Color-Word Task compared with F-S mid-morning (all < 0.05). Morning breakfast and exercise combine to improve short-term mathematical task performance and speed in adolescents.

Caffeine (CAF) mouth rinsing has been considered a practical nutritional strategy among athletes. Recent studies indicate that this nutritional strategy's efficacy may depend on the athlete's prandial state. Therefore, the main aim of the current study is to determine the effect of CAF mouth rinsing on a battery of soccer-specific tests of soccer players in fasted (FST) or fed states (FED).

Background: With the development of technology, easier access to the internet and its excessive use have led to problematic internet use (PIU). The prevalence of PIU and its association with lifestyle behaviors in adolescents have become subjects of increasing academic interest. This study aimed to determine the prevalence of PIU among Turkish high school students and to investigate its association with sleep, physical activity and dietary habits.

We respond to the article "Modifying the timing of breakfast improves postprandial glycaemia in people with type 2 diabetes: A randomised controlled trial" by Bravo-Garcia et al. While the study introduces an intriguing strategy for postprandial glycemic control, several methodological modification and detailed reporting could be done. Key variables such as participants' sleep-wake timing, daily schedules, and evening routines, which influence glucose metabolism, could be reported.
