This study aimed to determine the effects of a single bout exercise on mitochondria-mediated apoptotic signaling in cardiac and skeletal muscles. Fischer 344 rats (4 months old) were randomly divided into the control or a single bout of exercise group (n=10 each). The rats performed a single bout of treadmill exercise for 60 min. Mitochondria-mediated apoptotic signaling (e.g., Bax, Bcl-2, mitochondrial permeability transition pore [mPTP] opening, cytochrome c, and cleaved caspase-3) was measured in cardiac (e.g., left ventricle) and skeletal (e.g., soleus and white gastrocnemius) muscles. A single bout of exercise significantly decreased mPTP opening sensitivity in all tissues. However, a single bout of exercise did not show any statistical differences in Bax, Bcl-2, cytochrome c, and cleaved caspase-3 in all tissues measured. A single bout of exercise did not show definite results on characteristics of mitochondria-mediated apoptotic signaling. Therefore, further research is necessary to provide a more mechanistic understanding of the apoptosis pathway.

Background: Patients with schizophrenia spectrum disorder (SSD) suffer from impaired cognitive functions. Previous studies in healthy individuals have shown that a single bout of physical exercise benefits cognitive functions. Such enhancements in cognitive function would be highly beneficial, particularly for patients with SSD, as cognitive abilities play a vital role in both mental and physical health.

Chronic exercise training substantially improves skeletal muscle function and performance. The repeated demands and stressors of each exercise bout drive coordinated molecular adaptations within multiple cell types, leading to enhanced neuromuscular recruitment and contractile function, stem cell activation, myofiber hypertrophy, mitochondrial biogenesis, and angiogenesis, among others. To comprehensively profile molecular changes induced by combined resistance and endurance exercise training, we employed spatial transcriptomics coupled with immunofluorescence and computational approaches to resolve effects on myofiber and mononuclear cell populations in human muscle.

A single bout of exercise improves muscle insulin sensitivity for up to 48 hours via the AMP-activated protein kinase (AMPK). Limb ischemia activates AMPK in muscle, and subsequent reperfusion enhances insulin-stimulated vasodilation, potentially eliciting a more pronounced exercise effect with reduced workload. Here, we investigated the combined effect of upper leg intermittent ischemia-reperfusion (IIR) and continuous knee-extension exercise on muscle insulin sensitivity regulation.

: The Nordic hamstring exercise (NHE) effectively strengthens the hamstrings, reduces the risk of hamstring strain, and induces fatigue in the muscles; thus, post-NHE recovery strategies should be optimized. Foam rolling (FR) is a widely used method, with the belief that it can speed up recovery. Thus, this study investigated the acute and 48-h effects of FR following the NHE on muscle stiffness, pain pressure threshold (PPT), flexibility, countermovement jump (CmJ) height, and maximal voluntary isometric contraction (MVIC).

Introduction: Exercise interventions are less effective in generating weight loss in females compared to males suggesting that the menstrual cycle may be important. Fluctuations in ovarian hormones are proposed to alter the appetite-regulatory response to exercise across the menstrual cycle and no study has assessed the response in all distinct hormonal phases.
Purpose: To compare post-exercise appetite-regulating parameters following a single bout of MICT across three distinct menstrual phases.
