The effects of aerobic exercise training on inflammatory markers in adult tobacco smokers: A systematic review and meta-analysis of randomized controlled trials. Respir Med 2024; 231:107732. [PMID: 38971338 DOI: 10.1016/j.rmed.2024.107732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 06/19/2024] [Accepted: 07/03/2024] [Indexed: 07/08/2024]
Abstract
INTRODUCTION Aerobic exercise training may reduce systemic inflammation, but the effects of this on systemic inflammatory markers in adult tobacco smokers has not been systematically reviewed. Therefore, we evaluated the effects of aerobic exercise training on C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) in adult tobacco smokers using a systematic review and meta-analysis of randomized controlled trials. METHODS A comprehensive literature search was carried out using PubMed/Medline, Web of Science, EMBASE, Google Scholar, and hand search of bibliographies of the retrieved English or Persian articles up to August 2023. This review only included randomized controlled trials which investigated the effect of aerobic exercise training on CRP and TNF-α in adult smokers, based on a predefined inclusion and exclusion criteria. RESULTS A total of 1641 articles were identified. Six studies were included in the review and four evaluated CRP and two evaluated TNF-α in only males. The meta-analysis demonstrated that aerobic exercise training significantly decreased TNF-α concentrations in males (MD = -6.68, 95 % CI = -13.90 to -0.54, P = 0.05). CRP concentrations did not decrease significantly when the data from the four studies were pooled (MD = -0.17, 95 % CI = -0.37 to 0.03, P = 0.09). CONCLUSION Aerobic exercise training may reduce the concentration of TNF-α in male smokers, but it does not have a significant effect on CRP concentrations. However, these findings are based upon a small number of studies, that enrolled either exclusively male or female participants, and further investigation is necessary to increase statistical inference.

Chem Biol Interact 2023; 370:110315. [PMID: 36535313 DOI: 10.1016/j.cbi.2022.110315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 12/13/2022] [Accepted: 12/15/2022] [Indexed: 12/23/2022]
Abstract
Natural bioactive compound, Ursolic acid (UA), plus different types of exercise may exert the action on glycemic control, leading to clinical benefits in the prevention and treatment of aging/diabetes-associated complications. So, this study examined the effects of eight weeks combination of 250 mg of UA per day per kilogram of body weight of rat as well as resistance/endurance training on miR-133a expression across serum, bone marrow, skeletal muscle, and Connexin 43 (Cx43)-Runt-related transcription factor 2 (Runx2) signaling axis in high-fat diet and low-dose streptozotocin-induced T2D (here, HFD/STZ-induced T2D). The study was conducted on 56 male Wistar rats (427 ± 44 g, 21 months old), having HFD/STZ-induced T2D randomly assigned into 7 groups of 8 including (1) sedentary non-diabetic old rats (C); (2) sedentary type 2 diabetes animal model (D); (3) sedentary type 2 diabetes animal model + UA (DU); (4) endurance-trained type 2 diabetes animal model (DE); (5) resistance-trained type 2 diabetes animal model (DR); (6) endurance-trained type 2 diabetes animal model + UA (DEU); and (7) resistance-trained type 2 diabetes animal model + UA (DRU). Resistance training included a model of eight weeks of ladder resistance training at 60-80% maximal voluntary carrying capacity (MVCC) for five days/week. Treadmill endurance exercise protocol included eight weeks of repetitive bouts of low-/high-intensity training with 30%-40% and 60%-75% maximal running speed for five days/week, respectively. UA Supplementary groups were treated with 500 mg of UA per kg of high-fat diet per day. The results revealed significant supplement and exercise interaction effects for the BM miR-133a (p = 0.001), the bone marrow Runx2 (p = 0.002), but not the serum miR-133a (p = 0.517), the skeletal muscle miR-133a (p = 0.097) and the Cx43 (p = 0.632). In conclusion, only eight weeks of resistance-type exercise could affect miR-133a profile in muscles and osteoblast differentiation biomarker RUNX2 in aged T2D model of rats. 250 mg of UA per kilogram of body weight rat per day was administered orally, less than the sufficient dose for biological and physiological impacts on osteoblast differentiation biomarkers in aged T2D model of rats following eight weeks.

The wonder exerkines-novel insights: a critical state-of-the-art review. Mol Cell Biochem 2021; 477:105-113. [PMID: 34554363 PMCID: PMC8755664 DOI: 10.1007/s11010-021-04264-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Accepted: 09/17/2021] [Indexed: 02/07/2023]
Abstract
Several benefits can be acquired through physical exercise. Different classes of biomolecules are responsible for the cross-talk between distant organs. The secretome of skeletal muscles, and more widely the field of organokines, is ever-expanding. “Exerkine” has emerged as the umbrella term covering any humoral factors secreted into circulation by tissues in response to exercise. This review aims at describing the most interesting exerkines discovered in the last 3 years, which are paving the way for both physiological novel insights and potential medical strategies. The five exerkines identified all play a significant role in the healthy effect of exercise. Specifically: miR-1192, released by muscles and myocardium into circulation, by modulating cardioprotective effect in trained mice; miR-342-5p, located into exosomes from vascular endothelial cells, also a cardioprotective miRNA in trained young humans; apelin, released by muscles into circulation, involved in anti-inflammatory pathways and muscle regenerative capacity in rats; GDF-15, released into circulation from yet unknown source, whose effects can be observed on multiple organs in young men after a single bout of exercise; oxytocin, released by myoblasts and myotubes, with autocrine and paracrine functions in myotubes. The systemic transport by vesicles and the crosstalk between distant organs deserve a deep investigation. Sources, targets, transport mechanisms, biological roles, population samples, frequency, intensity, time and type of exercise should be considered for the characterization of existing and novel exerkines. The “exercise is medicine” framework should include exerkines in favor of novel insights for public health.

Effects of exercise on muscle mass, strength, and physical performance in older adults with sarcopenia: A systematic review and meta-analysis according to the EWGSOP criteria. Exp Gerontol 2021; 151:111420. [PMID: 34029642 DOI: 10.1016/j.exger.2021.111420] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 05/14/2021] [Accepted: 05/19/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND In 2018, the European Working Group on Sarcopenia in Older People (EWGSOP) updated the definition and the diagnosis criteria of sarcopenia. Previous systematic reviews have shown the effect of exercise on sarcopenia including people with different sarcopenia diagnostic criteria. OBJECTIVE This systematic review and meta-analysis aims to summarise and synthesise the evidence about the effect of exercise on muscle mass, strength and physical performance in older adults with sarcopenia according to the EWGSOP criteria. METHODS Major electronic databases were searched for articles published until September 2020. Randomised controlled trials (RCTs) and non-randomised interventional studies examining the effect of exercise on muscle mass, strength or physical performance in adults older than 60 years with sarcopenia according to the EWGSOP criteria were included. RESULTS Four RCTs and three non-randomised interventional studies with a total of 235 patients with sarcopenia were included. Five of the seven included studies reported a low risk of bias. Exercise showed a large effect on physical performance (d = 1.21, 95%CI [0.79 to 1.62]; P < 0.001), a medium effect on muscle strength (d = 0.51, 95%CI [0.25 to 0.76]; P < 0.001), and no effect on muscle mass (d = 0.27, 95%CI [-0.05 to 0.58]; P = 0.10). CONCLUSION The present systematic review showed an effect of exercise on physical performance and muscle strength but an inconsistent effect on muscle mass. The grading of recommendations assessment, development and evaluation criteria showed a low level of evidence in muscle mass, a low or moderate level of evidence in muscle strength and a high level of evidence in physical performance.

Characteristics of Physical Exercise Programs for Older Adults in Latin America: A Systematic Review of Randomized Controlled Trials. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18062812. [PMID: 33802095 PMCID: PMC8000929 DOI: 10.3390/ijerph18062812] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/13/2021] [Accepted: 02/18/2021] [Indexed: 02/06/2023]
Abstract
AIM To characterize physical exercise programs for older adults in Latin America. METHODS This review was conducted in accordance with the PRISMA statement. A search for randomized controlled trials (RCTs) published between the years 2015 and 2020 was performed in the Scopus, MedLine and SciELO databases. RESULTS A total of 101 RCTs were included. A large percentage of the studies had an unclear risk of bias in the items: selection, performance, detection and attribution. Furthermore, a heterogeneous level of compliance was observed in the CERT items. A total sample of 5013 older adults (79% women) was included. 97% of the studies included older adults between 60-70 years, presenting an adherence to the interventions of 86%. The studies were mainly carried out in older adults with cardiometabolic diseases. Only 44% of the studies detailed information regarding the place of intervention; of these studies, 61% developed their interventions in university facilities. The interventions were mainly based on therapeutic physical exercise (89% of the articles), with a duration of 2-6 months (95% of the articles) and a frequency of 2-3 times a week (95% of the articles) with sessions of 30-60 min (94% of the articles) led by sports science professionals (51% of the articles). The components of physical fitness that were exercised the most were muscular strength (77% of the articles) and cardiorespiratory fitness (47% of the articles). Furthermore, only 48% of the studies included a warm-up stage and 34% of the studies included a cool-down stage. CONCLUSIONS This systematic review characterized the physical exercise programs in older adults in Latin America, as well the most frequently used outcome measures and instruments, by summarizing available evidence derived from RCTs. The results will be useful for prescribing future physical exercise programs in older adults.

Abstract
OBJECTIVE Elderly patients continue to experience low levels of mobility during and following postoperative hospitalization that lead to persistent physical decline. Therefore, here we compared chronic resistance (CR) exercise against chronic aerobic (CA) exercise in ameliorating postoperative functioning and reducing proinflammatory muscular Toll-like receptor (TLR)-associated signaling in elderly postoperative patients. METHODS We conducted a prospective, randomized trial comparing the effects of 3 exercise programs (CR, CA, and CR + CA) in 66 elderly patients recovering from recent hip, femur, or pelvic fracture repair surgery. The primary outcomes were changes in anatomic/physical performance parameters (ie, maximal oxygen intake, endurance, quadriceps cross-sectional area, and maximum knee-extensor force). The secondary outcomes were changes in TLR/nuclear factor kappa beta signaling pathway marker expression. RESULTS Three of the 4 anatomic/physical performance parameters significantly improved for the CR and CR + CA cohorts. Muscular expression of myeloid differentiation primary response gene 88, transforming growth factor beta-activated kinase 1 (TLR signaling pathway markers), p50, p65, tumor necrosis factor α, and interleukin 6 (nuclear factor kappa beta signaling pathway markers) all showed significant reductions after CR and CR + CA. Serum expression of 2 key TLR4 ligands, heat shock protein 70 and serum amyloid A, also showed significant reductions after CR and CR + CA. CONCLUSIONS Three months of CR or CR + CA improves maximal oxygen consumption, quadriceps cross-sectional area, and maximum knee-extensor force while lowering muscular proinflammatory signaling markers in elderly adults with postoperative deconditioning.

Abstract
Sarcopenia is an age-related condition that is characterized by progressive and generalized loss of muscle mass and function. Exercise treatment has been the most commonly used intervention among elderly populations. We performed a systematic review and meta-analysis to evaluate the available literature related to the effects of exercise interventions/programs on muscle mass, muscle strength and physical performance in older adults with sarcopenia. We searched PubMed, EMBASE, MEDLINE and the Web of Science for randomized controlled trials and controlled clinical trials exploring exercise in older adults with sarcopenia published through July 2019 without any language restrictions. Pooled analyses were conducted using Review Manager 5.3, with standardized mean differences (SMDs) and fixed-effect models. A total of 3898 titles and abstracts were initially identified, and 22 studies (1041 individuals, 80.75% females, mean age ranged from 60.51 to 85.90 years) were included in the meta-analysis. The exercise programs in the studies consisted of 30 to 80 min of training, with 1 to 5 training sessions weekly for 6 to 36 weeks. Muscle strength (grip strength [SMD 0.57, 95 % CI 0.42 to 0.73, P <0.00001] and timed five chair stands [SMD -0.56, 95 % CI -0.85 to -0.28, P < 0.0001]) and physical performance (gait speed [SMD 0.44, 95 % CI 0.26 to 0.61, P < 0.00001] and the timed up and go test [SMD -0.97, 95 % CI -1.22 to -0.72, P < 0.00001]) showed significant improvement following exercise treatment, while no differences in muscle mass (ASM [SMD 0.15, 95 % CI -0.05 to 0.36, P = 0.15] and ASM/height2 [SMD 0.21, 95 % CI -0.05 to 0.48, P = 0.12]) were detected. Exercise programs showed overall significant positive effects on muscle strength and physical performance but not on muscle mass in sarcopenic older adults.

Abstract
BACKGROUND As the prevalence of neurodegenerative diseases (such as dementia) continues to increase due to population aging, it is mandatory to understand the role of exercise for maintaining/improving brain health. OBJECTIVES To analyse the impact of aerobic, strength and combined aerobic/strength exercise training on peripheral brain-derived neurotrophic factor (BDNF) concentrations in older adults (minimum age 60 years). METHODS This meta-analysis adhered to PRISMA guidelines. Inclusion criteria were: (i) studies with subjects aged ≥ 60 years, (ii) completing a single exercise bout or an exercise programme, with (iii) measurements of blood BDNF in the periphery; (iv) with comparison between (a) an intervention and control group or (b) two intervention groups, or (c) pre- and post-measurements of an exercise intervention without control group. Studies with specific interest in known chronic co-morbidities or brain diseases affecting the peripheral and/or central nervous system, except for dementia, were excluded. RESULTS In general, peripheral blood BDNF concentrations increased significantly after a single aerobic/strength exercise bout (Z = 2.21, P = 0.03) as well as after an exercise programme (Z = 4.72, P < 0.001). However, when comparing the different types of exercise within these programmes, the increase in the peripheral BDNF concentrations was significant after strength training (Z = 2.94, P = 0.003) and combined aerobic/strength training (Z = 3.03, P = 0.002) but not after (low-to-moderate intense) aerobic exercise training (Z = 0.82, P = 0.41). CONCLUSIONS Based on current evidence, to increase the peripheral blood BDNF concentrations in older adults, strength training and combined aerobic/strength training is effective. More studies are needed to examine the impact of aerobic exercise training.

Abstract
Oxidative stress is the core of most pathological situations, and its attribution toward disease conversion is not yet well established. The adaptive capacity of a cell can overcome ROS-induced pathology. However, when a cell fails to extend its maximum adaptive capacity against oxidative stress, it could lead a cell to misbehave or defunct from its normal functions. Any type of physical activity can increase the cells' maximum adaptive capacity, but aging can limit this. However, whether aging is the initiating point of reducing cells' adaptive capacity against oxidative stress or oxidative stress can induce the aging process is a mystery, and it could be the key to solving several uncured diseases. Paradoxically, minimum ROS is needed for cellular homeostasis. Nevertheless, finding factors that can limit or nullify the production of ROS for cellular homeostasis is a million-dollar question. Regular physical exercise is considered to be one of the factors that can limit the production of ROS and increase the ROS-induced benefits in the cells through inducing minimum oxidative stress and increasing maximum adapting capacity against oxidative stress-induced damages. The type and intensity of exercise that can produce such positive effects in the cells remain unclear. Therefore, this review discusses how physical exercise can help to produce minimal positive oxidative stress in preventing skeletal muscle aging.

Effect of Aerobic Exercise on Inflammatory Markers in Healthy Middle-Aged and Older Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Front Aging Neurosci 2019; 11:98. [PMID: 31080412 PMCID: PMC6497785 DOI: 10.3389/fnagi.2019.00098] [Citation(s) in RCA: 118] [Impact Index Per Article: 23.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Accepted: 04/10/2019] [Indexed: 12/29/2022] Open
Abstract
Background: Chronic inflammation plays a significant role in accelerating the aging process and is closely associated with the initiation and progression of a broad range of age-related diseases. Physical exercise is considered beneficial in alleviating these conditions, but the effects of aerobic exercise on inflammatory markers in a healthy population should be furtherly clarified. Objective: The purpose of this systematic review and meta-analysis was to evaluate the effect of aerobic exercise on inflammatory markers in middle-aged and older adults. Methods: The literature search was conducted utilizing PubMed, Web of Science, Embase, and the Cochrane Library from their inception through April 2018, and the reference lists were screened to identify appropriate studies. Only randomized controlled trials that investigated the effect of aerobic exercise on inflammatory markers in middle-aged and older adults were eligible for this review. Results: Eleven studies involving 1,250 participants were retrieved from the databases for analysis. The pooled results showed that aerobic exercise significantly reduced inflammatory markers (C-reactive protein (CRP): SMD = 0.53, 95% CI 0.26–0.11, p = 0.0002; tumor necrosis factor-alpha (TNF-α): SMD = 0.75, 95% CI 0.31–1.19, p = 0.0007; interleukin 6 (IL-6): SMD = 0.75, 95% CI 0.31–1.19, p = 0.0007). No significant improvement was found in relation to interleukin 4 (IL-4). Conclusions: Aerobic exercise may have a positive effect on reduction of CRP, TNF-α, and IL-6 in middle-aged and older adults. Further randomized controlled trials (RCTs) need to be conducted to determine the effect of aerobic exercise on additional inflammatory markers in the population of middle-aged and older adults.

Abstract
Parkinson's disease (PD) is the second most common neurodegenerative disease in the world. With the advent of an aging population and improving life expectancy worldwide, the number of PD patients is expected to increase, which may lead to an urgent need for effective preventive and diagnostic strategies for PD. Although there is increasing research regarding the pathogenesis of PD, there is limited knowledge regarding the prevention of PD. Moreover, the diagnosis of PD depends on clinical criteria, which require the occurrence of bradykinesia and at least one symptom of rest tremor or rigidity. However, converging evidence from clinical, genetic, neuropathological, and imaging studies suggests the initiation of PD-specific pathology prior to the initial presentation of these classical motor clinical features by years or decades. This latent stage of neurodegeneration in PD is a particularly important stage for effective neuroprotective therapies, which might retard the progression or prevent the onset of PD. Therefore, the exploration of risk factors and premotor biomarkers is not only crucial to the early diagnosis of PD but is also helpful in the development of effective neuroprotection and health care strategies for appropriate populations at risk for PD. In this review, we searched and summarized ∼249 researches and 31 reviews focusing on the risk factors and prodromal biomarkers of PD and published in MEDLINE.
