Article Abstract
Purpose: Exercise-induced adaptations, including neuroplasticity, are well studied for physical exercise that targets skeletal muscles. However, little is known about the neuroplastic potential of targeted speech and swallowing exercises. The current study aimed to gather preliminary data on molecular and functional changes associated with the neuroplastic effects of 4-week expiratory musculature-targeted resistance training in healthy young adults.
Method: Five healthy young adult men aged between 19 and 35 years, () = 28.8 (2.68) years, underwent 4 weeks of expiratory muscle strength training (EMST). We measured changes in maximum expiratory pressure (MEP), serum brain-derived neurotrophic factor (BDNF), and insulin-like growth factor 1 (IGF-1) levels at baseline and posttraining conditions. Furthermore, functional and structural magnetic resonance images were obtained to investigate the neuroplastic effects of EMST. We analyzed the effects of training using a linear mixed model for each outcome, with fixed effects for baseline and posttraining.
Results: MEP and serum BDNF levels significantly increased posttraining. However, this effect was not observed for IGF-1. A significant increase in functional activation in eight regions was also observed posttraining. However, we did not observe significant changes in the white matter microstructure.
Conclusions: Preliminary data from our study suggest targeted resistance training of expiratory muscles results in molecular and neuroplastic adaptations similar to exercise that targets skeletal muscles. Additionally, these results suggest that EMST could be a potential intervention to modulate (or prime) neurotrophic signaling pathways linked to functional strength gains and neuroplasticity.

High-Intensity Exercise and Hippocampal Integrity in Adults With Cannabis Use Disorder: A Randomized Clinical Trial.
JAMA Psychiatry
September 2025
School of Psychological Sciences, Monash University, Melbourne, Victoria, Australia.
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 Injuries in Endurance Athletes: A Review of Risk Factors, Screening and Evaluation Pearls, Preventive Strategies, and Evidence-Based Management Approaches.

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.

Inspired by the rigid exoskeleton and elastic inner tissues of crustaceans, a bilayer gel integrating high-strength rigidity and soft cushioning with high interfacial adhesion (1060 ± 40 J m ) is developed via a stepwise solid-liquid phase crosslinking strategy. Herein, a prefrozen high-concentration polyvinyl alcohol (PVA) solution forms a solid-state structural framework, while a subsequently cast low-concentration PVA solution generates a flexible layer. Partial thawing of the frozen gel during casting triggers molecular chain interpenetration at the interface, synergistically enhanced by controlled molecular penetration, freeze-thaw cycles, and salt-induced crystallization.

Current treatments for narcolepsy type 1 (NT1) have little impact on psychiatric, cognitive and metabolic comorbidities. Here, we evaluated the feasibility, safety and efficacy of a prospective Exercise Training (ET) program on sleep-related symptoms and comorbidities in NT1. Sedentary adult with NT1 participated in a 6-week supervised ET program followed by a 18-week self-directed program.

Background: Fine particulate matter has developmental toxicity, and midgestation is an important period for the development of foetal skeletal muscle. The ability of exercise to modulate skeletal muscle damage in mice exposed to PM during gestation remains unclear.
Methods: Pregnant C57BL/6 mice were exposed to 50 μg/m PM for 2 h on five consecutive days starting at embryonic day 12.
