RESUMEN

INTRODUCTION: The health status of adults with disabilities is recognized as a formal health disparity. Due to COVID-19, participation in wellness programs for this population has been restricted. To provide program participants with continued accessibility, one regional wellness program for adults with disabilities adopted a virtual format. The purpose of this research is to determine the effectiveness of a virtual wellness program for this population. METHODS: Study subjects consisted of adults with disabilities who participated in a regional virtual wellness program. A survey was developed and disseminated electronically to study participants through Qualtrics software. Part 1 of the survey included demographic information, while Part 2 surveyed participants' perceptions and satisfaction with the virtual program using a 5-point Likert scale. RESULTS: 10 out of 14 participants responded to the survey. Results indicated that the majority (80%) of participants utilized the program at least 1-2 times/week. All participants reported that, despite preferring in-person wellness classes, they were satisfied with the virtual format of the program. Positive responses were also reported for survey items related to self-perceived health and functional benefits from participation, degree of staff and peer support offered through virtual means, ease of technology use, and the degree of safety within the virtual environment. DISCUSSION: Given the health status of adults with disabilities during an ongoing global pandemic, continued restrictions limiting participation with in-person wellness programs is anticipated. Virtual formats may offer an advantageous solution to provide adults with disabilities with continued access to this essential programming. While the current study showed positive self-perceived health and functional benefits from participation, further research is needed to determine the effectiveness of this format through expanded and standardized objective outcome measures and to better understand factors that may impact participation.

RESUMEN

BACKGROUND: The early repolarization pattern (ERP) has recently been associated with cardiac events such as ventricular arrhythmias and sudden cardiac death. However, estimates of the prevalence of ERP vary widely, especially between the general population and physically active individuals. We performed this systematic review and meta-analysis to quantitatively evaluate the worldwide prevalence of ERP in the general population and physically active individuals. METHODS: We thoroughly searched the PubMed, EMBASE, Web of science, the Cochrane Library, and Scopus databases for relevant studies published until December 20, 2020. Studies in which prevalence was presented or could be estimated from eligible data were included. The pooled prevalence was analyzed using a random-effect model. RESULTS: Finally, we included 29 studies (182,135 subjects) in the general population and 14 studies (8087 subjects) in the physically active individuals. The worldwide pooled prevalence of ERP in the general population was 11.6% (95% confidence interval [CI]: 10.0%-13.3%). The incidence of ERP was 17.0% and 6.2% in men and women, respectively. The prevalence was 20.9% in blacks, 13.4% in Asians, and 10.1% in Caucasians. Additionally, the prevalence of ERP in physically active individuals was 33.9% (95% CI: 25.3%-42.6%). CONCLUSION: A significant difference in the worldwide prevalence of ERP is revealed in this study. The ERP is highly prevalent in men, blacks, and physically active individuals.

RESUMEN

ABSTRACT: The aim of this study was to assess the physical activity level of health care professionals, as well as the differences by sex, age, academic background, and among different health care professions.This is an cross-sectional study.Health care settings in the Valencian Community, Spain.A total of 647 health care professionals.Physical activity was assessed with the European Health Interview Survey-Physical Activity Questionnaire (EHIS-PAQ) that includes the assessment of work-related physical activity, transport-related physical activity, health-enhancing physical activity, muscle-strengthening physical activity, and total physical activity.93.51% of all health care professionals were physically active at work. Transport-related physical activity and health-enhancing physical activity were significantly lower in women (21.62% vs 41.86%, P < .001; and 50.19% vs 68.99%, P < .001, respectively). In addition, compliance with health-enhancing and muscle-strengthening physical activity guidelines were lower in older professionals (42.7% vs 61.84%, P < .001; and 47.57% vs 61.84%, P < .001, respectively). Those with higher education were more compliant with health-enhancing and muscle-strengthening physical activity guidelines (58.55% vs 45.69%, P = .002; and 60.24% vs 48.28%, P = .003, respectively). Moreover, 67.98% of physiotherapists performed health-enhancing physical activity and 67.54% muscle-strengthening physical activity regularly, and significant differences in all outcomes were observed compared to the rest of health care professionals (P < .05). Technicians showed lower work-related and total physical activity than nurses and nursing assistants (74.55% vs 90.37%, P = .002; and 83.64% vs 95.72%, P < .001, respectively). Additionally, nursing assistants showed higher work-related physical activity compared to nurses (97.18% vs 90.37%, P = .008).Most health care professionals showed an appropriate level of physical activity. Men performed more transport-related and health-enhancing physical activity than women. Younger professionals and those with higher education were more compliant with health-enhancing and muscle-strengthening physical activity guidelines. Physiotherapists were more physically active when compared to the rest of health care professionals.

RESUMEN

ABSTRACT: The pathophysiology of sarcopenia is complex and must be further explored. While metabolic acidosis may be a risk factor for sarcopenia, it remains unclear whether acidic urine is related to sarcopenia. The purpose of the present study was to investigate the association between sarcopenia and urine pH in the elderly.An elderly population (n = 123 [male = 46]; mean age = 81.7 years) was classified into 2 groups based on the sarcopenia status according to their strength, requirement of assistance in walking, their ability to rise from a chair their ability to climb stairs, and their history of falls. Urinalysis was measured using dipstick tests.The sarcopenia group (n = 32) was significantly older, had less exercise habit and showed a lower urine pH (mean pH = 5.5) in comparison to the nonsarcopenia group (mean pH = 6.2, P < .01). A multivariate analysis that was adjusted for age, male sex, body mass index, uro-renal variables and exercise habit revealed that urine pH (odds ratio, 0.43; 95% confidence interval, 0.22-0.85, P = .02), age and less exercise habit were independently and significantly associated with sarcopenia.The findings of the present study suggest a potential association between metabolic acidosis and the pathophysiology of sarcopenia in the elderly. As urine pH is a simple biomarker that can be obtained using dipstick tests, it is therefore expected to be helpful for detecting sarcopenia in the clinical setting.

RESUMEN

Introduction: Pre-dive altitude exposure may increase respiratory fatigue and subsequently augment exercise ventilation at depth. This study examined pre-dive altitude exposure and the efficacy of resistance respiratory muscle training (RMT) on respiratory fatigue while diving at altitude. Methods: Ten men (26±5 years; VO2peak: 39.8±3.3 mL• kg-1•min-1) performed three dives; one control (ground level) and two simulated altitude dives (3,658 m) to 17 msw, relative to ground level, before and after four weeks of resistance RMT. Subjects performed pulmonary function testing (e.g., inspiratory [PI] and expiratory [PE] pressure testing) pre- and post-RMT and during dive visits. During each dive, subjects exercised for 18 minutes at 55% VO2peak, and ventilation (VE), breathing frequency (ƒb,), tidal volume (VT) and rating of perceived exertion (RPE) were measured. Results: Pre-dive altitude exposure reduced PI before diving (p=0.03), but had no effect on exercise VE, ƒb, or VT at depth. At the end of the dive in the pre-RMT condition, RPE was lower (p=0.01) compared to control. RMT increased PI and PE (p<0.01). PE was reduced from baseline after diving at altitude (p<0.03) and this was abated after RMT. RMT did not improve VE or VT at depth, but decreased ƒb (p=0.01) and RPE (p=0.048) during the final minutes of exercise. Conclusion: Acute altitude exposure pre- and post-dive induces decrements in PI and PE before and after diving, but does not seem to influence ventilation at depth. RMT reduced ƒb and RPE during exercise at depth, and may be useful to reduce work of breathing and respiratory fatigue during dives at altitude.

RESUMEN

Artificial muscle materials promise incredible applications in actuators, robotics and medical apparatus, yet the ability to mimic the full characteristics of skeletal muscles into synthetic materials remains a huge challenge. Herein, inspired by the dynamic sacrificial bonds in biomaterials and the self-strengthening of skeletal muscles by physical exercise, high performance artificial muscle material is prepared by rearrangement of sacrificial coordination bonds in the polyolefin elastomer via a repetitive mechanical training process. Biomass lignin is incorporated as a green reinforcer for the construction of interfacial coordination bonds. The prepared artificial muscle material exhibits high actuation strain (>40%), high actuation stress (1.5 MPa) which can lift more than 10,000 times its own weight with 30% strain, characteristics of excellent self-strengthening by mechanical training, strain-adaptive stiffening, and heat/electric programmable actuation performance. In this work, we show a facile strategy for the fabrication of intelligent materials using easily available raw materials.

RESUMEN

Heart failure with preserved ejection fraction (HFpEF) is a major public health problem that affects half of all patients with HF. It is rising in prevalence, is associated with high morbidity and mortality, and has very few effective treatments. HFpEF is currently understood as a heterogeneous syndrome originating from the interplay of cardiac and extracardiac abnormalities. The most important pathophysiology in patients with HFpEF is diastolic dysfunction, which presents with impairments in relaxation or increases in chamber stiffness that lead to an increase in left ventricular filling pressures at rest or during exercise that causes dyspnea.

RESUMEN

Soft, skin-integrated electronic sensors can provide continuous measurements of diverse physiological parameters, with broad relevance to the future of human health care. Motion artifacts can, however, corrupt the recorded signals, particularly those associated with mechanical signatures of cardiopulmonary processes. Design strategies introduced here address this limitation through differential operation of a matched, time-synchronized pair of high-bandwidth accelerometers located on parts of the anatomy that exhibit strong spatial gradients in motion characteristics. When mounted at a location that spans the suprasternal notch and the sternal manubrium, these dual-sensing devices allow measurements of heart rate and sounds, respiratory activities, body temperature, body orientation, and activity level, along with swallowing, coughing, talking, and related processes, without sensitivity to ambient conditions during routine daily activities, vigorous exercises, intense manual labor, and even swimming. Deployments on patients with COVID-19 allow clinical-grade ambulatory monitoring of the key symptoms of the disease even during rehabilitation protocols.

RESUMEN

PURPOSE: This article provides an overview of a diverse group of primary headache disorders that are categorized in the International Classification of Headache Disorders, 3rd Edition (ICHD-3), as "other primary headache disorders." This article provides clinicians with a distilled understanding of the diagnoses and their epidemiology, pathophysiology, and management. RECENT FINDINGS: Cough-induced headache requires neuroimaging to exclude posterior fossa pathology and recently has been reported as a common symptom in patients with CSF-venous fistula. Clinical overlap is observed between patients with primary exercise headache and primary headache associated with sexual activity. Patients with recurrent thunderclap headache associated with sexual activity should be presumed to have reversible cerebral vasoconstriction syndrome until proven otherwise. De novo external-pressure headache is a common sequela among health care workers using personal protective equipment during the COVID-19 pandemic. New daily persistent headache is an important mimicker of chronic migraine or chronic tension-type headache and is distinguished by a daily-from-onset progression of persistent headache; a treatment-refractory course is often observed, and early involvement of a multidisciplinary team, including a psychotherapist, is advised. SUMMARY: Patients with primary headache disorders that are classified as "other primary headache disorders" have presentations with unique diagnostic and management considerations. The disorders are highly recognizable, and an appreciation of the diagnoses will aid clinicians in providing safe and effective care for patients presenting with headache.

RESUMEN

Introduction: Patients with acromegaly show musculoskeletal symptoms which may persist despite disease control. Increased i.m. fat fraction is a known cause of muscle dysfunction in several disorders. Objective: To assess the degree of fat fraction in thigh muscles of controlled acromegaly patients and its relationship with muscle dysfunction. Methods: In a cross-sectional study, we included 36 patients with controlled acromegaly and 36 matched controls. We assessed the percentage of fat fraction in each thigh muscle, using MRI 2-point Dixon sequence, and muscle performance and strength using the gait speed, timed up and go, 30-s chair stand, and hand grip strength tests. We evaluated joint symptoms using the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC). Results: Intramuscular fat fraction was greater in patients than controls (P < 0.05 for muscle compartments, rectus femoris (RF), vastus intermedius (VI), adductor magnus (AM) and semimembranosus). Patients had slower gait speed and poorer performance on the 30-s chair stand and timed up and go tests than controls (P < 0.05). The greater fat fraction in the combined anterior-posterior compartment and in each muscle was associated with worse performance on timed up and go (P < 0.05). The fat fraction in the anterior-posterior compartment predicted performance on timed up and go after adjusting for muscle area, IGF-I and WOMAC functional and pain scores (ß = 0.737 P < 0.001). Conclusions: Patients with controlled acromegaly have greater thigh i.m. fatty infiltration, which is associated with muscle dysfunction. Futures studies are needed to elucidate the mechanisms underlying this relationship.

RESUMEN

Obesity is usually linked to oxidative stress, which can lead to damage to biomolecules. The combination of aerobic and strength exercises seems to induce health benefits in obese individuals, but little is known about the effects of combined physical exercise on redox homeostasis and DNA damage in this population. Thus, the aim of the current study was to determine the effects of 16 weeks of combined physical exercise on biomarkers of oxidative stress and DNA damage in obese women. 17 obese women underwent 16 weeks of a combined physical training program, 3 times per week. Anthropometric and biochemical parameters, serum superoxide dismutase (SOD) and glutathione peroxidase activity, plasma 8-isoprostane levels, and DNA and chromosomal damage were evaluated before and after physical training. Combined physical exercise training decreased body weight (83.2 ± 9.6 vs. 80.2 ± 9.6 kg), body mass index (33.8 ± 3.6 vs. 32.6 ± 3.7 kg·m-2), body fat (40.2 ± 2.6 vs. 39.0 ± 3.2%), and waist circumference (99.3 ± 9.4 vs. 94.1 ± 8.8 cm), while the fat-free mass was augmented (59.9 ± 2.9 vs. 60.7 ± 3.1 kg). Moreover, blood glucose reduced (113.5 ± 29.6 vs. 107.3 ± 28.9 mg/dL) along with high-density lipoprotein (54.6 ± 18.1 vs. 59.0 ± 18.8 mg/dL), TSH (2.1 ± 1.1 vs. 2.6 ± 1.2 mIU/mL), and free T4 (0.9 ± 0.1 vs. 1.12 ± 0.2 ng/dL) increase after physical exercise training. Plasma 8-isoprostane levels (17.24 ± 7.9 vs. 29.11 ± 17.44 pg/mL) and DNA damage (34.16 ± 7.1 vs. 45.96 ± 5.8% DNA in tail) were also higher after physical training. No changes were observed in chromosomal damage levels. These results suggest that 16 weeks of combined exercise training 3 times per week is effective in reducing body fat but also increases oxidative stress and DNA damage in obese women.

RESUMEN

OBJECTIVE: To determine whether greater physical activity could modify the negative association of APOE ε4 with longitudinal cognitive changes in early Parkinson disease (PD) and to uncover the disease-specific mechanism for explaining such benefits of physical activity. METHODS: We used data from the Parkinson's Progression Markers Initiative cohort. Because self-reported physical activity, measured by the Physical Activity Scale of the Elderly, was initiated at 2 years after enrollment, this longitudinal analysis was based on assessments performed at years 2, 3, and 4. Cognitive function was measured annually with the Montreal Cognitive Assessment (MoCA). Dopamine transporter (DAT) imaging was performed at years 2 and 4. We assessed the interactive associations between physical activity and the APOE ε4 allele on the longitudinal changes in MoCA scores and striatal DAT activities. RESULTS: A total of 173 patients with early PD (age 63.3 ± 10.0 years, 27% APOE ε4 carriers) were included. The APOE ε4 allele showed a steeper rate of cognitive decline than the non-APOE ε4 allele (estimate -1.33, 95% confidence interval [CI] -2.12 to -0.47, p = 0.002). However, there was a significant interaction between physical activity and APOE ε4 such that higher physical activity was related to slower APOE ε4-related cognitive decline (estimate 0.007, 95% CI 0.003-0.011, p = 0.001). No significant interaction was found between physical activity and the APOE ε4 allele regarding the change in striatal DAT activities. CONCLUSION: Increased physical activity attenuated APOE ε4-related vulnerability to early cognitive decline in patients with PD. This protective effect did not appear to be mediated by striatal dopaminergic function. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov Identifier: NCT01141023. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that increased physical activity was associated with decreased APOE ε4-related early cognitive decline in patients with PD.

RESUMEN

The coronavirus disease-2019 (COVID-19) pandemic has changed the conduct of clinical trials. For studies with physical function and physical activity outcomes that require in-person participation, thoughtful approaches in transitioning to the remote research environment are critical. Here, we share our experiences in transitioning from in-person to remote assessments of physical function and activity during the pandemic and highlight key considerations for success. Details on the development of the remote assessment protocol, integration of a two-way video platform, and implementation of remote assessments are addressed. In particular, procedural challenges and considerations in transitioning and conducting remote assessments will be discussed in terms of efforts to maintain participant safety, maximize study efficiency, and sustain trial integrity. Plans for triangulation and analysis are also discussed. Although the role of telehealth platforms and research activities in remote settings are still growing, our experiences suggest that adopting remote assessment strategies are useful and convenient in assessing study outcomes during, and possibly even beyond, the current pandemic. Trial register and number: ClinicalTrials.gov [NCT03728257].

RESUMEN

To examine basic COVID-19 knowledge, coping style and exercise behavior among the public including government-provided medical cloud system treatment app based on the internet during the outbreak. Besides, to provide references for developing targeted strategies and measures on prevention and control of COVID-19. We conducted an online survey from 11th to 15th March 2020 via WeChat App using a designed questionnaire. As well as aim to diagnose COVID-19 earlier and to improve its treatment by applying medical technology, the "COVID-19 Intelligent Diagnosis and Treatment Assistant Program (nCapp)" based on the Internet of Things. Valid information was collected from 1893 responders (47.07% males and 52.93% females aged 18-80 years, with a mean age of 31.05 ± 9.86) in 20 provincial-level regions across China. From the responders, 92.90% and 34.81% were scaled pass and good and above scores for the knowledge about the novel coronavirus epidemic. 38.44% were scaled poor scores and only 5.40% were scaled good and above scores for appropriate behavior coping with the pandemic. Among the responders, 52.14% reported having active physical exercise in various places during the previous 1 week. For all the responders, appropriate behavior coping correlated positively with physical exercise (p < 0.05); the daily consumed time for getting the epidemic-related information correlated positively with the score for cognition on the epidemic's prevention measures (r = 0.111, p < 0.01) and on general knowledge about the epidemic (r = 0.087, p < 0.01). Targeted and multiple measures for guidance on the control of COVID-19 among the public should be promoted to improve the cognition on basic knowledge, behaviors and treatment.

RESUMEN

AIMS: This study aimed to predict the variation in future fundamental movement skills (FMS), physical activity (PA) and body mass index (BMI) from prior FMS, PA, and BMI in British pre-schoolers. METHODS: British pre-schoolers (n = 177) underwent assessment of FMS, via the Test of Gross Motor Development 2 (TGMD-2), BMI, and PA, via accelerometer at two time points one year apart. Regression analysis was used to predict the change in PA and BMI in Year 2 from FMS variables in Year 1 and Year 2. RESULTS: Variation in FMS performance between individuals predicted a significant amount of change in BMI, with 12.3 and 9.8% of the change in Year 2 BMI data explained by change in Year 1 and Year 2 FMS data, respectively. Change in FMS performance between individuals predicted a significant amount of change in PA, but was better at predicting change in sedentary activity rather than light or moderate-vigorous activities. A combination of run, throw, dribble, and kick performance predicted 46.1% of the change in sedentary activity between individuals in the 2nd year of testing. CONCLUSIONS: FMS mastery at four years of age predicts children's BMI and time spent sedentary at five years of age.

RESUMEN

In the midst of the COVID-19 pandemic, Remote Patient Monitoring technologies are highly important for clinicians and researchers. These connected-health technologies enable monitoring of patients and facilitate remote clinical trial research while reducing the potential for the spread of the novel coronavirus. There is a growing requirement for monitoring of the full 24 h spectrum of behaviours with a single research-grade sensor. This research describes a free-living and supervised protocol comparison study of the Verisense inertial measurement unit to assess physical activity and sleep parameters and compares it with the Actiwatch 2 actigraph. Fifteen adults (11 males, 23.4 ± 3.4 years and 4 females, 29 ± 12.6 years) wore both monitors for 2 consecutive days and nights in the free-living study while twelve adults (11 males, 23.4 ± 3.4 years and 1 female, 22 ± 0 years) wore both monitors for the duration of a gym-based supervised protocol study. Agreement of physical activity epoch-by-epoch data with activity classification of sedentary, light and moderate-to-vigorous activity and sleep metrics were evaluated using Spearman's rank-order correlation coefficients and Bland-Altman plots. For all activity, Verisense showed high agreement for both free-living and supervised protocol of r = 0.85 and r = 0.78, respectively. For physical activity classification, Verisense showed high agreement of sedentary activity of r = 0.72 for free-living but low agreement of r = 0.36 for supervised protocol; low agreement of light activity of r = 0.42 for free-living and negligible agreement of r = -0.04 for supervised protocol; and moderate agreement of moderate-to-vigorous activity of r = 0.52 for free-living with low agreement of r = 0.49 for supervised protocol. For sleep metrics, Verisense showed moderate agreement for sleep time and total sleep time of r = 0.66 and 0.54, respectively, but demonstrated high agreement for determination of wake time of r = 0.83. Overall, our results showed moderate-high agreement of Verisense with Actiwatch 2 for assessing epoch-by-epoch physical activity and sleep, but a lack of agreement for activity classifications. Future validation work of Verisense for activity cut-point potentially holds promise for 24 h continuous remote patient monitoring.

RESUMEN

Összefoglaló. A cardiovascularis megbetegedések kialakulását és progresszióját jelentosen befolyásolja az életmód, ezen belül a fizikai aktivitás. A rendszeres testmozgás csökkenti a szív- és érrendszeri kórképek kockázatát, többek között a magas vérnyomásra, a zsíranyagcsere-eltérésekre és az elhízásra gyakorolt kedvezo hatásán keresztül, továbbá független tényezo a cardiovascularis halálozás szempontjából is. Az artériás érfali merevség az elasztikus artériák falát alkotó extracelluláris mátrix degeneratív eltéréseinek következtében alakul ki a különbözo kockázati tényezok hatására. Korábban, különbözo populációkon már igazolták az érfali merevség prediktív értékét a cardiovascularis események kialakulásának tekintetében. A pulzushullám-terjedési sebesség mérése a leggyakrabban alkalmazott módszer az érfali merevség meghatározására. A pulzushullám-terjedési sebesség mérésének hasznát a cardiovascularis kimenetel és élettartam becslésében számos populációs szintu követéses vizsgálat igazolja. Jelen munkánkban áttekintjük a rendszeres fizikai aktivitás, az érfali merevség, az érelmeszesedés és a cardiovascularis események közötti összefüggéseket. Összefoglaljuk az edzésnek és az érfali merevség paramétereinek kapcsolatát egészséges populáción vizsgáló legfontosabb tanulmányok eredményeit. Megállapítjuk, hogy az érfali merevség figyelemre méltó, érdekes biomarker a cardiovascularis kockázat becslése során a rendszeresen sportoló személyek esetén is. Mindezek alapján, tekintve annak prognosztikai hasznát, felmerül a pulzushullám-terjedési sebesség mérésének beillesztése a klinikai döntéshozatali folyamatba mind amator, mind professzionális sportolók esetében. Orv Hetil. 2021; 162(16): 615-622. Summary. The development and progression of cardiovascular disorders is importantly dependent on lifestyle factors, including physical activity. Regular physical activity decreases cardiovascular morbidity by ameliorating risk factors such as hypertension, dyslipidemia and obesity, moreover, also independently affects cardiovascular mortality. Arterial stiffness results from a degenerative process affecting mainly the extracellular matrix of elastic arteries under the effect of risk factors. Previously, the independent predictive value of arterial stiffness for cardiovascular events has been demonstrated in various populations. Pulse wave velocity is the most commonly used method for the assessment of arterial stiffness. The value of measuring pulse wave velocity to predict cardiovascular health outcomes and longevity has been established in several population-based longitudinal studies. In this review, we summarize the main associations between regular physical exercise, arterial stiffness, atherosclerotic burden and incident cardiovascular events. We cite findings from the major studies focusing on the effect of training on arterial stiffness parameters in healthy subjects. We conclude that arterial stiffness is emerging as an interesting biomarker for cardiovascular risk stratification in subjects doing regular physical activity. Therefore, the incorporation of pulse wave velocity measurement into clinical decision-making could be indicated in the case of both amateur and professional athletes, given the prognostic information it provides.

RESUMEN

As life expectancy has increased, particularly in developed countries, due to medical advances and increased prosperity, age-related neurological diseases and mental health disorders have become more prevalent health issues, reducing the well-being and quality of life of sufferers and their families. In recent decades, due to reduced work-related levels of physical activity, and key research insights, prescribing adequate exercise has become an innovative strategy to prevent or delay the onset of these pathologies and has been demonstrated to have therapeutic benefits when used as a sole or combination treatment. Recent evidence suggests that the beneficial effects of exercise on the brain are related to several underlying mechanisms related to muscle-brain, liver-brain and gut-brain crosstalk. Therefore, this review aims to summarize the most relevant current knowledge of the impact of exercise on mood disorders and neurodegenerative diseases, and to highlight the established and potential underlying mechanisms involved in exercise-brain communication and their benefits for physiology and brain function.

RESUMEN

BACKGROUND AND OBJECTIVES: With the emergence of a global pandemic, new challenges have arisen. Among them are issues relating to exercising, and perceived benefits of and barriers to exercising, particularly when many people find their opportunities for exercise limited by lockdowns. The aim of this study was to investigate how COVID­19 has affected Turkish society's perceptions of exercise and physical activity levels. METHOD: This descriptive and cross-sectional study of 410 eligible participants used an online demographic background survey, the International Physical Activity Questionnaire and the Exercise Benefits/Barriers Scale. RESULTS: The isolation period affects individuals' physical activity levels, with results indicating minimal activity levels in the general population. Higher levels of physical activity were associated with increases in the perception of exercise benefits and decreases in perceived barriers to exercise. DISCUSSION: Reducing the perception of barriers related to exercise can increase the feasibility and promote both physical and mental health through physical activity.
