Abstract
Complications such as diabetes and preeclampsia can occur during pregnancy. Moderate-intensity exercise can prevent such complications by releasing placentokines and exerkines, such as apelin, adiponectin, leptin, irisin, and chemerin. Exercise and apelin increase thermogenesis and glucose uptake in pregnancy by activating AMPK, PI3K, PGC-1α, AKT1, UCP3, and sarcolipin. Exercise increases apelin levels to reduce preeclampsia symptoms by increasing eNOS, NO, placental growth factor (PlGF), and VEGF and decreasing levels of fms-like tyrosine kinase 1 (sFlt-1), soluble endoglin (sEng), and oxidative stress. A negative relationship has been reported between plasma leptin and VO2peak/kg and VO2peak in women with gestational diabetes. In active women, decreases in leptin levels reduce the risk of preeclampsia by ~ 40%. Higher adiponectin levels are associated with greater physical activity and lead to increased insulin sensitivity. Increased adiponectin levels in preeclampsia and exercise counteract inflammatory and atherogenic activities while also having vascular protective effects. Exercise increases irisin levels that correlate negatively with fasting glucose, insulin concentration, and glycosylated hemoglobin levels. Irisin augments mRNA expression levels of UCP1 and cell death-inducing DNA fragmentation factor-like effector A (cidea) to cause browning of adipose tissue, increased thermogenesis, and increased energy consumption. Irisin concentrations in mothers with preeclampsia in the third trimester negatively correlate with systolic and diastolic blood pressure. Expression levels of chemerin, IL-6, and TNF-α are increased in gestational diabetes, and the increases in chemerin in late pregnancy positively correlate with the ratio of sFlt-1 to PlGF as a marker of preeclampsia. The effects of physical exercise on placentokines and exerkines in women at various stages of pregnancy remain poorly understood.

Abstract
BACKGROUND Adenosine triphosphatase inhibitory factor 1 (IF1) is a key protein involved in energy metabolism. IF1 has been linked to various age-related diseases, although its relationship with physical activity (PA) remains unclear. Additionally, the apolipoprotein A-I (apoA-I), a PA-modulated lipoprotein could play a role in this relationship because it shares a binding site with IF1 on the cell-surface ATP synthase. We examined here the associations between chronic PA and plasma IF1 concentrations among older adults, and we investigated whether apoA-I mediated these associations. METHODS In the present work, 1096 healthy adults (63.8% women) aged 70 years and over who were involved in the Multidomain Alzheimer Prevention Trial study were included. IF1 plasma concentrations (square root of ng/mL) were measured at the 1-year visit of the Multidomain Alzheimer Prevention Trial, while PA levels (square root of metabolic equivalent task min/week) were assessed using questionnaires administered each year from baseline to the 3-year visit. Multiple linear regressions were performed to investigate the associations between the first-year mean PA levels and IF1 concentrations. Mediation analyses were conducted to examine whether apoA-I mediated these associations. Mixed-effect linear regressions were carried out to investigate whether the 1-year visit IF1 concentrations predicted subsequent changes in PA. RESULTS Multiple linear regressions indicated that first-year mean PA levels were positively associated with IF1 concentrations (B = 0.021; SE = 0.010; p = 0.043). Mediation analyses revealed that about 37.7% of this relationship was mediated by apoA-I (Bab = 0.008; SE = 0.004; p = 0.023). Longitudinal investigations demonstrated that higher concentrations of IF1 at the 1-year visit predicted a faster decline in PA levels over the subsequent 2 years (time × IF1: B = -0.148; SE = 0.066; p = 0.025). CONCLUSION This study demonstrated that regular PA is associated with plasma IF1 concentrations, and it suggests that apoA-I partly mediates this association. Additionally, this study found that baseline concentrations of IF1 can predict future changes in PA. However, further research is needed to fully understand the mechanisms underlying these observations.

Abstract
Exercise and increased physical activity are vital components of the standard treatment guidelines for many chronic diseases such as diabetes, obesity and cardiovascular disease. Although strenuous exercise cannot be recommended to people with numerous chronic conditions, walking is something most people can perform. In comparison to high-intensity training, the metabolic consequences of low-intensity walking have been less well studied. We present here a feasibility study of a subject who performed an exercise intervention of low-intensity, non-fatiguing walking on a deskmill/treadmill for 200 min daily, approximately the average time a German spends watching television per day. This low-impact physical activity has the advantages that it can be done while performing other tasks such as reading or watching TV, and it can be recommended to obese patients or patients with heart disease. We find that this intervention led to substantial weight loss, comparable to that of bariatric surgery. To study the metabolic changes caused by this intervention, we performed an in-depth metabolomic profiling of the blood both directly after walking to assess the acute changes, as well as 1.5 days after physical activity to identify the long-term effects that persist. We find changes in acylcarnitine levels suggesting that walking activates fatty acid beta oxidation, and that this mitochondrial reprogramming is still visible 1.5 days post-walking. We also find that walking mildly increases gut permeability, leading to increased exposure of the blood to metabolites from the gut microbiome. Overall, these data provide a starting point for designing future intervention studies with larger cohorts.

Abstract
BACKGROUND Angiogenesis constitutes a major mechanism responsible for exercise-induced beneficial effects. Our previous study identified a cluster of differentially expressed extracellular vesicle microRNAs (miRNAs) after exercise and found that some of them act as exerkines. However, whether these extracellular vesicle miRNAs mediate the exercise-induced angiogenesis remains unknown. METHODS A 9-day treadmill training was used as an exercise model in C57BL/6 mice. Liver-specific adeno-associated virus 8 was used to knock down microRNA-122-5p (miR-122-5p). Human umbilical vein endothelial cells were used in vitro. RESULTS Among these differentially expressed extracellular vesicle miRNAs, miR-122-5p was identified as a potent pro-angiogenic factor that activated vascular endothelial growth factor signaling and promoted angiogenesis both in vivo and in vitro. Exercise increased circulating levels of miR-122-5p, which was produced mainly by the liver and shuttled by extracellular vesicles in mice. Inhibition of circulating miR-122-5p or liver-specific knockdown of miR-122-5p significantly abolished the exercise-induced pro-angiogenic effect in skeletal muscles, and exercise-improved muscle performance in mice. Mechanistically, miR-122-5p promoted angiogenesis through shifting substrate preference to fatty acids in endothelial cells, and miR-122-5p upregulated endothelial cell fatty-acid utilization by targeting 1-acyl-sn-glycerol-3-phosphate acyltransferase (AGPAT1). In addition, miR-122-5p increased capillary density in perilesional skin tissues and accelerated wound healing in mice. CONCLUSION These findings demonstrated that exercise promotes angiogenesis through upregulation of liver-derived extracellular vesicle miR-122-5p, which enhances fatty acid utilization by targeting AGPAT1 in endothelial cells, highlighting the therapeutic potential of miR-122-5p in tissue repair.

Abstract
Vascular mitochondria constantly integrate signals from environment and respond accordingly to match vascular function to metabolic requirements of the organ tissues, while mitochondrial dysfunction contributes to vascular aging and pathologies such as atherosclerosis, stenosis, and hypertension. As an effective lifestyle intervention, exercise induces extensive mitochondrial adaptations through vascular mechanical stress and the increased production and release of reactive oxygen species and nitric oxide that activate multiple intracellular signaling pathways, among which peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) plays a critical role. PGC-1α coordinates mitochondrial quality control mechanisms to maintain a healthy mitochondrial pool and promote endothelial nitric oxide synthase activity in vasculature. The mitochondrial adaptations to exercise improve bioenergetics, balance redox status, protect endothelial cells against detrimental insults, increase vascular plasticity, and ameliorate aging-related vascular dysfunction, thus benefiting vascular health. This review highlights recent findings of mitochondria as a central hub integrating exercise-afforded vascular benefits and its underlying mechanisms. A better understanding of the mitochondrial adaptations to exercise will not only shed light on the mechanisms of exercise-induced cardiovascular protection, but may also provide new clues to mitochondria-oriented precise exercise prescriptions for cardiovascular health.

Abstract
Physical inactivity increases the chance of many adverse health conditions. It has been well recognized that exercise exerts widespread beneficial effects in health promotion and disease prevention. However, there remain many unknowns in the understanding of the complex biology and performance behind diversity in response to exercise among populations and individuals. The exercise-afforded health benefits are not sufficiently researched, which to some extent holds back the translation of exercise biology to society and the widespread adoption of physical activity promotion. A comprehensive understanding of the physiology of exercise and pathogenic processes underpinning physical inactivity-associated disorders will facilitate the development of new preventative and therapeutic strategies to improve health and well-being at the whole-body level. In this chapter, we will discuss some important questions that remain to be addressed in the research of health-promoting benefits of exercise.

Abstract
Accumulating evidence has demonstrated that exercise training not only reduces cardiovascular disease risk but also provides direct endogenous cardiovascular protection. The mechanisms that have been proposed to be responsible for exercise-induced cardioprotection include intrinsic myocardial changes such as increased cytosolic antioxidant capacity and altered mitochondrial phenotype, myokine-mediated metabolic and anti-inflammatory effects in the cardiovascular system, and systemic effects on the cardiovascular system via interorgan cross talk. There remains much to be elucidated in the mechanisms for exercise-afforded cardioprotection. This chapter reviews exercise-induced acute and chronic responses in cardiovascular system, the epidemiological evidence of exercise training and cardiorespiratory fitness in the primary and secondary prevention of cardiovascular diseases, and the current understanding of the mechanisms of exercise-induced cardiovascular protective effects.
