Objective: To examine whether the completion of a course of study relating to preventive health and lifestyle risk factors was associated with alterations in health behaviours. Design: Within-group intervention, repeated-measures design. Setting: Health behaviours of university students studying a course focused on health and well-being. Method: Undergraduate university students (n = 56) completed a questionnaire assessing health behaviours at the start and end of a course which was oriented towards a healthy lifestyle, concentrating on preventive health and lifestyle risk factors. Beliefs about the importance of various health behaviours addressed within the course content were also assessed. Results: Physical activity was unaltered across the duration of the course, while a number of dietary behaviours were improved, including an increase in the weekly frequency of eating breakfast, reduced frequency of adding salt to meals, increased frequency of choosing reduced fat dairy options, reduced frequency of consuming drinks with added sugar, and consuming alcohol (p = 0.05). Conclusion: Health-focused course content may benefit students through the knowledge gained that can be applied in future professional settings and also via positive alterations in their own health behaviours. These positive influences on health behaviour in early adulthood may have implications for lifelong health and well-being.

Aim: To examine the within‐person variability in plasma glucose responses to moderate‐intensity morning exercise in young individuals with type 1 diabetes after overnight fasting and under basal insulin conditions. Methods: In this pilot study, eight participants completed 40 min of moderate‐intensity exercise at 60% V̇O2 peak on three separate days. The within‐person standard deviation (SDw) in plasma glucose response was analysed both during and 1 h after exercise using the two visits per participant most closely matched by pre‐exercise plasma glucose level. Results: When the two closest matched visits per individual were included for analysis, mean (±SD) change in plasma glucose level was −1.8 ± 1.1 mmoL/L during exercise and −0.6 ± 1.0 mmoL/L during recovery, with the SDw of these changes being 0.5 mmol (95% CI 0.2, 0.8) during exercise and 0.8 mmoL/L (95% CI 0.4, 1.3) during recovery. The median intra‐individual difference in plasma glucose level change was 0.3 mmoL/L [IQR 0.1, 0.7] during exercise and 0.8 mmoL/L [IQR 0.4, 1.0] during recovery. Conclusion: Within‐person plasma glucose responses to moderate‐intensity exercise may be reproducible under fasting and basal insulin conditions and similar pre‐exercise plasma glucose levels. This finding may assist the design of future studies investigating both the reproducibility of glycaemic responses to exercise and blood glucose management for individuals with type 1 diabetes.

The aim of this study was to examine the effects of static stretching during warm-up on repeated sprint performance and also to assess any influence of the order in which dynamic activities (i.e., run-throughs and drills) and static stretching are conducted. Thirteen male team sport players completed a repeated sprint ability test consisting of three sets of maximal 6 x 20-m sprints (going every 25 seconds) after performing one of three different warm-up protocols in a within-subjects counterbalanced design. Each warm-up protocol involved an initial 1000-m jog, followed by either dynamic activities only (D), static stretching followed by dynamic activities (S-D), or dynamic activities followed by static stretching (D-S). First (FST), best (BST) and total (TST) 20-m sprint times were determined for each individual set of the repeated sprint ability test and overall (3 sets combined). Although consistent significant differences were not observed between trials for TST, BST, and FST, the mean values for TST in all individual sets and overall were generally slowest in the D-S condition (D = 60.264 [+ or -] 1.127 seconds; S-D = 60.347 [+ or -] 1.774 seconds; D-S = 60.830 [+ or -] 1.786 seconds). This trend was supported by moderate to large effect sizes and qualitative indications of 'possible' or 'likely' benefits for TST, BST, and FST for the D and S-D warm-ups compared to D-S. No significant differences or large effect sizes were noted between D and S-D, indicating similar repeated sprint ability performance. Overall, these results suggest that 20-m repeated sprint ability may be compromised when static stretching is conducted after dynamic activities and immediately prior to performance (D-S).

Aerobic exercise (AE) and strength exercise (SE) are reported to induce discrete and specific appetite-related responses; however, the effect of combining AE and SE (i.e., combined exercise; CE) remains relatively unknown. Twelve inactive overweight men (age: 48 ± 5 y; BMI: 29.9 ± 1.9 kg⋅m²) completed four conditions in a random order: 1) nonexercise control (CON) (50 min seated rest); 2) AE (50 min cycling; 75% VO2peak); 3) SE (10 x 8 leg extensions; 75% 1RM); and 4) CE (50% SE + 50% AE). Perceived appetite, and appetite-related peptides and metabolites were assessed before and up to 2 h postcondition (0P, 30P, 60P, 90P, 120P). Perceived appetite did not differ between trials (p < .05). Acylated ghrelin was lower at 0P in AE compared with CON (p = .039), while pancreatic polypeptide (PP) was elevated following AE compared with CON and CE. Glucose-dependent insulinotropic peptide (GIPtotal) was greater following all exercise conditions compared with CON, as was glucagon, although concentrations were generally highest in AE (p < .05). Glucose was acutely increased with SE and AE (p < .05), while insulin and C-peptide were higher after SE compared with all other conditions (p < .05). In inactive, middle-aged men AE, SE and CE each have their own distinct effects on circulating appetite-related peptides and metabolites. Despite these differential exercise-induced hormone responses, exercise mode appears to have little effect on perceived appetite compared with a resting control in this population.
