Article Abstract
Objectives: This study aimed to investigate the relationship between changes in physical activity and frailty among middle-aged and older adults in Korea, using panel data from the 2006-2022 Korean Longitudinal Study of Aging (KLoSA).
Design: Retrospective observational study.
Setting: For this longitudinal panel study, data were sourced from the KLoSA dataset.
Participants: We analysed data from 5594 participants (2855 males and 2739 females) extracted from KLoSA data collected between 2006 and 2022.
Primary And Secondary Outcome Measures: The frailty index was calculated based on 6 clinical domains comprising 34 age-related health deficits. Changes in physical activity were categorised as persistently inactive, decreased, increased or persistently active. Logistic regression analysis using generalised estimating equations was conducted to assess the association between changes in physical activity and frailty.
Results: The persistently active group (OR=0.45, 95% CI: 0.40 to 0.50) showed a lower likelihood of frailty than did the persistently inactive group. In the group that increased their physical activity, the OR was 0.57 (95% CI: 0.52 to 0.63), and higher ORs were observed for current smokers and those residing in rural areas.
Conclusions: This study demonstrated that persistent and increased physical activity is associated with lower frailty in middle-aged and older adults in Korea. Therefore, participation in physical activity in the older adults is one of the important ways to prevent frailty.

In wheat allergy dependent on augmentation factors (WALDA), allergic reactions occur when wheat ingestion is combined with exercise or rarely other augmentation factors. We analyzed clinical characteristics and disease burden in recreationally active and trained individuals with WALDA diagnosed by oral challenge test. Clinical characteristics, serological data, and quality of life (QOL) questionnaires were analyzed and completed with follow-up interviews.

Introduction: Reverse total shoulder arthroplasty is a well-established treatment for patients with rotator cuff tear arthropathy. The outcome after reverse total shoulder arthroplasty has been investigated in several studies and national registries. However, the treatment has not been compared to non-surgical treatment.

Introduction: People with rheumatic and musculoskeletal diseases are advised to do aerobic exercise for symptom relief and to reduce the risk of cardiovascular disease. Continuous exercise at an intensity causing a rate of perceived exertion of 15, on a 6-20-point Borg scale, exemplifies such exercise. Also, the instruction "Now you need to increase your heart rate" is used before aerobic exercise.

Background: The objective of this study was to compare the effects of daily consumption of white potatoes compared with white rice on cardiometabolic health in individuals with type-2 diabetes (T2D).
Objective: To determine the effects of white potato consumption compared to white rice (a commonly consumed refined grain) on indices of glycemic control and cardiovascular health in individuals with overweight or obesity and T2D.
Methods: In this randomized crossover study, comparative control trial, 24 adults with T2D [45-80 y, body mass index (kg/m) 25-40] consumed baked white potatoes (100 g) or calorie-matched white rice (75 g) daily for 12 wk, separated by a 2-wk washout, with assessments of glycemic control, lipids, inflammation, blood pressure, endothelial function, and body composition at baseline (only 1 baseline visit included as a covariate in statistical analyses), 6 wk, and 12 wk.
Contrasting Realities in Injury Management: Strategies Employed by Performance Nutritionists and Dietitians in Ireland (Part A).
Curr Dev Nutr

Department of Sport, Exercise and Nutrition, Atlantic Technological University, Galway, Ireland.
Background: Nutrition underpins athletic performance, enhancing training, reducing injury risk, and accelerating recovery. In the event of an injury, performance dietitians (PDs) and nutritionists' (PNs) play a vital role by tailoring nutritional strategies to support tissue repair, optimize athlete's recoveries, and return to play.
Objectives: This study explored nutritional strategies recommended and employed by Irish PDs and PNs to assess, manage, and support athletes during the initial stages of sports-related injuries.
