“…It is now clear that moderate aerobic exercise has a positive effect on health and body weight, as well as on increasing cognitive abilities. Moreover, Orexin-A levels regulate the concentration of glucose: hyperglycemia could be caused by an insufficient Orexin-A signal, blocking physical activity and promoting an overweight state (Catenacci and Wyatt, 2007;Cox, 2017;Monda et al, 2019).…”

The Important Role of Adiponectin and Orexin-A, Two Key Proteins Improving Healthy Status: Focus on Physical Activity

Exercise represents the most important integrative therapy in metabolic, immunologic and chronic diseases; it represents a valid strategy in the non-pharmacological intervention of lifestyle linked diseases. A large body of evidence indicates physical exercise as an effective measure against chronic non-communicable diseases. The worldwide general evidence for health benefits are both for all ages and skill levels. In a dysregulated lifestyle such as in the obesity, there is an imbalance in the production of different cytokines. In particular, we focused on Adiponectin, an adipokine producted by adipose tissue, and on Orexin-A, a neuropeptide synthesized in the lateral hypothalamus. The production of both Adiponectin and Orexin-A increases following regular and structured physical activity and both these hormones have similar actions. Indeed, they improve energy and glucose metabolism, and also modulate energy expenditure and thermogenesis. In addition, a relevant biological role of Adiponectin and Orexin A has been recently highlighted in the immune system, where they function as immune-suppressor factors. The strong connection between these two cytokines and healthy status is mediated by physical activity and candidates these hormones as potential biomarkers of the beneficial effects induced by physical activity. For these reasons, this review aims to underly the interconnections among Adiponectin, Orexin-A, physical activity and healthy status. Furthermore, it is analyzed the involvement of Adiponectin and Orexin-A in physical activity as physiological factors improving healthy status through physical exercise.

“…The existing evidence indicates that healthy eating habits and physical activity (PA) are a prerequisite for maintaining a normal body weight [11][12][13][14][15]. According to World Health Organization (WHO) guidelines, obese individuals should increase their PA to ≥150 min/ week in order to boost their metabolic rate and energy expenditure and achieve a negative energy balance [16].…”

“…People with obesity are entangled in a vicious circle: as their weight discourages them from exercise, they tend to avoid PA and so they become more obese. It is therefore important for unhealthy habits to be changed step by step because trying to modify them at once can have a demotivating effect and impair the effectiveness and sustainability of the process [11,14,[24][25][26][27].…”

Effect of 12-Week Interventions Involving Nordic Walking Exercise and a Modified Diet on the Anthropometric Parameters and Blood Lipid Profiles in Overweight and Obese Ex-Coal Miners

et al. 2020

Background: Overweight and obesity after retirement are likely to be caused by unhealthy eating habits and the energy intake exceeding the energy expenditure. Objectives: This study was designed to assess the effects of two 12-week interventions involving, respectively, either regular physical activity or a modified lower-calorie diet on the anthropometric parameters and blood lipid profiles in overweight and obese retired miners with lipid disorders. Design:The study participants (n = 30, aged 58.7 ± 4.1 years, body height 174.8 ± 7.3 cm, body weight 96.6 ± 13.9 kg) were randomly assigned to 2 intervention groups: the Nordic walking group (NW), which exercised with intensity from 60 to 70% of participants' maximal heart rates for 1 h 3 times a week, and the modified diet group (MD). Modification of the diet consisted of reducing the daily energy intake by 30%, increasing the dietary content of mono-and polyunsaturated fatty acids and dietary fiber, and reducing the proportion of saturated fatty acids. The variables assessed at baseline and after 6 and 12 weeks were: anthropometric parameters (body weight, fat mass content [FM], fat percentage [BF], BMI, waist circumference [WC], hip circumference [HC], and waist-to-hip ratio [WHR]) and blood lipid indicators (total cholesterol [TC], triglycerides [TG], low density lipoprotein cholesterol [LDL-C], and high density lipoprotein cholesterol [HDL-C]). Results: The body weight of the participants in the NW was lower at week 12 by an average of 5 kg, BMI 7%. In the MD, the postintervention concentrations of TC and TG were within the reference range. Conclusion: Both 12-week interventions improved the anthropometric parameters and blood lipid profiles of retired heavy manual workers, with the improvements being more pronounced in the dieting group.

“…El estado actual de la evidencia respalda la importancia del ejercicio (actividad física estructurada y planificada) en la mejora de la salud cardiovascular, la sensibilidad a la insulina, el control glucémico de la diabetes tipo 2, la presión arterial y la depresión (22) . Sin embargo, cabe preguntar si el ejercicio en sí mismo contribuye a la pérdida de peso y los esfuerzos de mantenimiento del peso corporal (24) .…”

Resumen Introducción: en los últimos años la obesidad en niños y adultos ha aumentado. La mejor estrategia para el control de esta enfermedad es el manejo médico-nutricional donde la actividad física tiene un papel importante. Sin embargo, todavía existen controversias sobre su impacto en la pérdida y el control del peso corporal. Objetivos: presentar evidencia actualizada sobre el papel de la actividad física en la etiología de la obesidad y su utilidad en la pérdida y en el control del peso. Métodos: se realizó una búsqueda en PubMed y Google Scholar con las palabras obesidad, gasto energético y actividad física. Se procede a abordar en primer lugar el papel del gasto energético de la actividad física en la obesidad, luego se analiza el impacto del ejercicio en la pérdida y el control del peso en adultos y niños, y por último se tratan los aspectos más importantes del músculo como órgano endocrino y su papel en los efectos benéficos del ejercicio. Resultados: la actividad física constante, en una duración mayor a lo recomendado, contribuye a la pérdida y al mantenimiento de peso. Asimismo, tiene un papel preventivo en enfermedades cardiovasculares, osteoporosis, riesgo de fractura, y cáncer de colon, pulmón, próstata, endometrio y de mama. Conclusiones: la actividad física tiene efectos benéficos demostrados para la salud, en especial para el control de las enfermedades crónicas, para mantener la pérdida de peso a largo plazo y para preservar la masa corporal magra durante una alimentación con restricción energética.
