Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1712-1728, December 2024. Limited data exist regarding the impact of exercise intensity on irisin release and its association with insulin sensitivity in individuals of differing obesity status. The objective of this study was to investigate the impact of exercise intensity on the acute release of […]

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1611-1621, December 2024. Carbohydrate (CHO) and caffeine (CAF) mouth rinsing have been independently reported to benefit sport performance. The proposed mechanisms by which mouth rinsing CHO exerts an influence are reported to be different from those for mouth rinsing CAF. However, the potential ergogenic effects

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1622-1635, December 2024. Resistance training (RT) promotes skeletal muscle (Skm) hypertrophy, increases muscular strength, and improves metabolic health. Whether changes in fat-free mass (FFM; a surrogate marker of muscle hypertrophy) moderate RT-induced improvements in glucose homeostasis has not been determined, despite extensive research on the

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1636-1645, December 2024. Disabling atrial fibrillation (AF)-related symptoms and different testing settings may influence day-to-day cardiopulmonary exercise testing (CPET) measurements, which can affect exercise prescription for high-intensity interval training (HIIT) and moderate-to-vigorous intensity continuous training (M-VICT) and their outcomes. This study examined the reliability of

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1646-1657, December 2024. Intense exercise training with insufficient recovery time is associated with reductions in neuromuscular performance. However, it is unclear how single muscle fibre mechanical function and myofibrillar Ca2+ sensitivity contribute to these impairments. We investigated the effects of overload training on joint-level neuromuscular

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1658-1665, December 2024. Affective experiences have been shown to influence attitudes and future behaviors related to physical activity, but no studies have related these experiences to physical literacy or examined affective experiences in quality physical education (QPE). The aim of this study was to describe

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1666-1677, December 2024. Skeletal muscle echo intensity (EI) is affected by ageing and physical activity; however, the effects of nutrition are less understood. The aim of this study was to explore whether habitual nutrient intake may be associated with ultrasound-derived EI. Partial least squares regression

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1678-1691, December 2024. There is limited evidence on how exposure to digital marketing of unhealthy foods affects youth’s dietary behaviours. This study therefore aimed to examine the association between youth’s self-reported digital food marketing exposure and dietary intakes, and explore predictors of frequent unhealthy food

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1692-1700, December 2024. Controlled Nutritional Status (CONUT) scores have been developed as quantitative tools that can be employed to gauge the nutritional status of individual patients. However, there has been very little research investigating the association between these CONUT scores and the function of the

Applied Physiology, Nutrition, and Metabolism, Volume 49, Issue 12, Page 1701-1711, December 2024. Cognitive function is improved acutely after aerobic and/or resistance exercise, but it is unclear if the types of muscle contraction can influence this effect. This study tested the hypothesis that undertaking an acute bout of exercise with eccentric than concentric contractions would
