Resistance training not only can improve or maintain muscle mass and strength, but also has favorable physiological and clinical effects on cardiovascular disease and risk factors. This scientific statement is an update of the previous (2007) American Heart Association scientific statement regarding resistance training and cardiovascular disease. Since 2007, accumulating evidence suggests resistance training is a safe and effective approach for improving cardiovascular health in adults with and without cardiovascular disease. This scientific statement summarizes the benefits of resistance training alone or in combination with aerobic training for improving traditional and nontraditional cardiovascular disease risk factors. We also address the utility of resistance training for promoting cardiovascular health in varied healthy and clinical populations. Because less than one-third of US adults report participating in the recommended 2 days per week of resistance training activities, this scientific statement provides practical strategies for the promotion and prescription of resistance training.

Aim: This study aims to compare the weekly resistance training (RT) frequency between people with diabetes, prediabetes, and without diabetes.
Methods: A total of 536,703 participants from 2017 to 2023 Behavioral Risk Factors Surveillance System were included in the analysis. Unadjusted and adjusted Poisson regression was performed to compare weekly resistance training frequency among participants with different diabetes statuses (without diabetes, prediabetes, and with diabetes).

Objectives: This study evaluated the effects of proximal core training on biomechanical risk factors and strength parameters in individuals at high risk of anterior cruciate ligament (ACL) injury (specifically: those exhibiting pathological movement patterns, neuromuscular deficits or biomechanical risk factors) and compared direct versus indirect interventions. We hypothesised that targeted training enhances dynamic knee stabilisation and hip control during high-risk manoeuvres, with direct approaches providing superior biomechanical benefits through neuromuscular control optimisation.
Design: Systematic review and meta-analysis using the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach.

Study Question: Does weight loss from a hypocaloric dietary intervention improve antral follicle dynamics in women with PCOS?
Summary Answer: During a 3-month hypocaloric dietary intervention, women with PCOS who experienced clinically meaningful weight loss showed more organized antral follicle development including fewer recruitment events, but no change in the overall frequency of selection, dominance, or ovulation.
What Is Known Already: There is a spectrum of disordered antral follicle development in women with PCOS including excessive follicle recruitment and turnover, decreased frequency of selection and dominance, and failure of ovulation. Lifestyle intervention aimed at weight loss is recommended to improve metabolic health in women with PCOS yet benefits on ovarian follicle development and ovulation are unclear.

Importance: Cannabis is the most commonly used illicit drug, with 10% to 30% of regular users developing cannabis use disorder (CUD), a condition linked to altered hippocampal integrity. Evidence suggests high-intensity interval training (HIIT) enhances hippocampal structure and function, with this form of physical exercise potentially mitigating CUD-related cognitive and mental health impairments.
Objective: To determine the impact of a 12-week HIIT intervention on hippocampal integrity (ie, structure, connectivity, biochemistry) compared with 12 weeks of strength and resistance (SR) training in CUD.

Bone stress injury is a common musculoskeletal condition presenting with insidious bony pain that is progressive and occurs with a number of intrinsic or extrinsic risk factors, particularly with a recent change in training. When elicited, the presence of bony tenderness remains the most important component of the physical exam, although reproduction at deeper sites is a challenge and requires a high index of suspicion and imaging for diagnosis. MRI should be utilized as the gold standard for diagnosis, grading, and return-to-sport timing prognosis when available, with plain radiographs used as first-line imaging.
