Summary: This study examined the inter-day reliability of RMR, RER, MFO, and Fatmax in healthy adult males using the Ergostik gas analyzer. The results showed no significant differences in these measures between two consecutive days, indicating good inter-day reliability of the instrument in healthy men.

Summary: Higher dietary fiber intake is associated with increased basal fat oxidation, while higher fat intake is associated with maximal fat oxidation during exercise in sedentary adults. However, these associations are attenuated after considering factors such as sex, age, and energy intake.

Summary: A study comparing two high-intensity interval training protocols on obese men showed similar effects in improving regional body composition and fat oxidation. Both training programs effectively reduced trunk fat and increased leg lean mass, while enhancing fat oxidation during exercise. HIIT also resulted in improved peak fat oxidation, VO2peak, and decreased blood lactate levels at submaximal intensities.

Summary: The study shows that the effects of training on whole-body fat oxidation in young men may be attenuated in middle-aged men. This indicates that the ability to oxidize fat during exercise declines with age, but regular exercise training can help counteract this decline.

Summary: Recent literature suggests that exercise has powerful biological effects beyond generating a calorie deficit, including impacts on mitochondrial function, chemical messenger release, and epigenetic alterations. This review aims to summarize the current literature on the hypothesis that these exercise effects not explained by energy deficit are related to muscle fuel substrate balance. This balance can be measured with reliable techniques, providing insight into metabolic disturbances associated with sedentary lifestyles and obesity, as well as adaptations in trained individuals.

Summary: The study showed that performing 6 sessions of HIIT over 5 days was as effective as doing 6 sessions over 2 weeks in increasing VO2max and endurance capacity, and even more effective in improving submaximal exercise fat oxidation.

Summary: This study aimed to analyze the characteristics of treadmill protocols used to measure maximum fat oxidation (MFO) and the intensity at which it occurs (FATmax) in sedentary individuals. A total of 12 articles were selected from 223 identified articles, and all the protocols involved gradual increases in speed and incline. The duration of each stage ranged from 3 to 6 minutes, and the speed ranged from 3 to 7.5 km/h with 2% increases in incline.

Summary: This study aimed to provide exercise intensity guidelines and training volume recommendations for maximizing fat oxidation in patients with obesity. It was found that relative heart rate, rather than relative oxygen uptake, should be used for establishing FATmax reference values in these patients. A heart rate of 61-66% HRpeak should be recommended to patients with > 35% body fat, while a heart rate of 57-64% HRpeak should be recommended to patients with body fat < 35%.

Summary: The study found that New Zealand blackcurrant extract can enhance fat oxidation in female endurance athletes during cycling, but has no significant impact on other physiological and metabolic responses. Changes in fat oxidation are significantly correlated with individual body composition parameters, especially for young women with higher body fat percentages in the legs, arms, and trunk.

Summary: The study aimed to compare the effects of typical competition versus high-intensity intermittent warm-up on thermoregulatory responses and repeated sprint performance during wheelchair rugby game play. The results showed that high-intensity warm-up may increase thermal strain in players with spinal cord injury during the game, but it does not impact their repeated sprint performance.

Summary: This study investigated the reflections of adults who experienced the death of a parent during their young age. The findings suggest that parental bereavement can lead to feelings of distance and isolation, as well as emotional and physical impact. Many participants reported experiencing personal growth after the loss, but acknowledged that life will never be the same. The importance of support, understanding, and re-grief triggers was highlighted. The study also revealed a translational gap between existing support services and the actual uptake of talking therapies.

Summary: In June 2021, a workshop organized by the European branch of ILSI addressed the role of postprandial glycaemic response in pediatric health and highlighted research gaps in this area. The workshop emphasized the importance of understanding glycaemic responses in pediatric populations, and the changes in metabolism and dietary needs from infancy to adolescence. The lack of scientific data on glucose and insulin profiles in response to commonly consumed foods by children, as well as the need for long-term evidence and suitable predictors for future health effects, were identified as significant research gaps.

Summary: Preventing cardiometabolic diseases has benefits for both human health and the planet. This review paper focuses on the acute responses of young people to physical activity and breakfast intake, and explores the interaction between their behavior and cardiometabolic health from an environmental sustainability perspective. The findings suggest that moderate- to high-intensity exercise can reduce postprandial glucose, insulin, and triacylglycerol concentrations in young people, while breakfast consumption may enhance physical activity and reduce glycaemic responses. These findings are important for disease prevention and reducing greenhouse gas emissions associated with diagnosis and treatment.

Summary: A single exercise session can suppress appetite by affecting appetite-regulating hormones. However, the effects of short, regular physical activity breaks on appetite are unclear. This study found that breaking up sitting with high-intensity physical activity can acutely suppress appetite, but appetite-regulating hormones may not be responsible for these effects.

Summary: The aim of this study was to determine the appetite-related responses to breaking up prolonged sitting with physical activity bouts differing in frequency and duration among adult females. The findings suggest that breaking up sitting does not lead to compensatory changes in appetite, appetite hormones or energy intake regardless of physical activity bout duration and frequency among adult females.

Summary: This study aimed to assess the performance of FreeStyle Libre Flash glucose monitoring (FGM) during an oral glucose tolerance test (OGTT) and treadmill exercise in healthy adolescents. The results showed that FGM is a feasible alternative to reflect postprandial glycaemia in healthy adolescents, reducing the need for repeated finger pricks.

Summary: Cardiovascular disease (CVD) is highly prevalent and sedentary behavior has been identified as an independent risk factor for CVD. This article discusses the association between sedentary time and CVD risk markers, the acute effects of reducing sedentary time on CVD risk markers, and the effectiveness of longer-term sedentary behavior interventions on CVD risk. Findings suggest that breaking up sedentary time improves cardiovascular risk markers and interventions may benefit cardiovascular risk in the longer term.
