Background: Leisure-time physical activity is the preferred domain by the population to follow physical activity recommendations, helping to maintain a healthy lifestyle. However, the main issue in this type of physical activity intervention is massive dropout.
Methods: Using monthly data from 20,908 leisure/fitness center members (2011-2016), we estimate a discrete-time duration model to examine how membership duration influences dropout probability, addressing cross-sectional limitations. Additionally, we assess the explanatory power of different covariate groups.
Results: Dropout probability follows a seasonal pattern, peaking within the first 3 months before declining and stabilizing over time. Short-term memberships and low attendance frequency significantly increase dropout risk, confirming that membership conditions and time-related variables are key predictors of retention. Additionally, macroeconomic factors particularly unemployment play a crucial role in increasing dropout probability.
Conclusions: These results could help both recreational facility managers and policymakers to design strategies to reduce dropout among physical activity practitioners, in particular, in the current situation generated by the COVID-19 crisis.

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.

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.
