Exercise training fosters the health and performance of the cardiovascular system, and represents nowadays a powerful tool for cardiovascular therapy. Exercise exerts its beneficial effects through reducing cardiovascular risk factors, and directly affecting the cellular and molecular remodelling of the heart. Traditionally, moderate endurance exercise training has been viewed to determine a balanced and revertible physiological growth, through cardiomyocyte hypertrophy accompanied by appropriate neoangiogenesis (the Athlete's Heart). These cellular adaptations are due to the activation of signalling pathways and in particular, the IGF-1/IGF-1R/Akt axis appears to have a major role. Recently, it has been shown that physical exercise determines cardiac growth also through new cardiomyocyte formation. Accordingly, burgeoning evidence indicates that exercise training activates circulating, as well as resident tissue-specific cardiac, stem/progenitor cells. Dissecting the mechanisms for stem/progenitor cell activation with exercise will be instrumental to devise new effective therapies, encompassing myocardial regeneration for a large spectrum of cardiovascular diseases.

The study aimed to determine if virtual reality (VR) games could enhance neuromuscular control and improve anticipatory and compensatory strategies in ball-kicking for soccer players. It was a single-blind randomized clinical trial involving 32 male soccer players with chronic ankle instability. Participants were divided into two groups: VR games and balance training.

Although the connection between muscular strength and flatfoot condition is well-established, the impact of corrective exercises on these muscles remains inadequately explored. This study aimed to assess the impact of intrinsic- versus extrinsic-first corrective exercise programs on muscle morphometry and navicular drop in boys with flexible flatfoot. Twenty-five boys aged 10-12 with flexible flatfoot participated, undergoing a 12-week corrective exercise program, with a shift in focus at six weeks.

Wheelchair propulsion is a fundamental skill in wheelchair sports, particularly in wheelchair tennis. To achieve optimal mobility during wheelchair athletic performance, it is essential to consider propulsion techniques. This study examines the effect of push frequency and stroke duration on wheelchair maneuverability, measured by velocity during propulsion, among wheelchair tennis athletes.

Resolvin D1 (RvD1) is an endogenous anti-inflammatory mediator that modulates the inflammatory response and promotes inflammation resolution. RvD1 has demonstrated neuroprotective effects in various central nervous system contexts; however, its role in the pathophysiological processes of intracerebral hemorrhage (ICH) and the potential protective mechanisms when combined with exercise rehabilitation remain unclear. A mouse model of ICH was established using collagenase, and treatment with RvD1 combined with three weeks of exercise rehabilitation significantly improved neurological deficits, muscle strength, learning, and memory in ICH mice while reducing anxiety-like behavior.

Microtextured microneedles are tiny needle-like structures with micron-scale microtextures, and the drugs stored in the microtextures can be released after entering the skin to achieve the effect of precise drug delivery. In this study, the skin substitution model of Ogden's hyperelastic model and the microneedle array and microtexture models with different geometrical parameters were selected to simulate and analyse the flow of the microtexture microneedle arrays penetrating the skin by the finite-element method, and the length of the microneedles was determined to be 200 μm, the width 160 μm, and the value of the gaps was determined to be 420 μm. A four-pronged cone was chosen as the shape of microneedles, and a rectangle was chosen as the shape of the drug-carrying microneedle.
