Occupational stress and physical activity in employees

Keywords: Motor activity, burnout, professional, depersonalization, occupational health services, young adult. Introducción La actividad física constituye un aspecto determi- nante de la calidad de vida. La Organización Mun- dial de la Salud (OMS) informa que la inactividad física es responsable de más de dos millones de muertes por año; el sedentarismo duplica el ries- go de enfermedades cardiovasculares, diabetes y obesidad y aumenta sustancialmente el riesgo de hipertensión arterial y otras enfermedades (Kalil, 2004). Frente a esto, la OMS propone la realiza- ción de actividad física de intensidad moderada mínimo 30 minutos, preferiblemente todos los días, los cuales pueden realizarse de forma frac- cionada a lo largo del día en periodos de no me- nos de 10 minutos, y a partir de actividades coti- dianas como caminar, subir escaleras, trabajar en el jardín o en las tareas de la casa.

Exhaustive physical exercise causes a decrease in oxidative stress and an increase in salivary total antioxidant activity of elite triathlete

Exhaustive physical exercise causes a decrease in oxidative stress and an increase in salivary total antioxidant activity of elite triathlete

The aim of this research was to study the effect of exhaustive physical exercise (triathlon) on uric acid (UA), total antioxidant activity (TAA), lipid hydroperoxides and nitric oxide (NO) metabolite, nitrite, in the saliva of elite triathletes. Stimulated saliva was sampled from 12 elite triathletes, 1 h before and immediately after competition. UA was assayed by enzymatic method, TAA by ABTS method, lipid hydroperoxides by FOX method and nitrite concentration by the Griess reaction. Exhaustive exercise caused an increase in both salivary UA concentration and TAA immediately after competition. On the other hand, there was a decrease in salivary lipid hydroperoxides. These results suggested that exhaustive exercise causes a decrease in salivary lipid hydroperoxides, a marker of oxidative stress, and this result could be explained by the fact that both UA and TAA increased after the triathlon.

threats and physical aggression (Andrew et al., 2008). Stressors related to the content of the task are psychosocial risk factors at work. Psychosocial risk factors are specifi cally defi ned as those conditions in a work situation that have the capacity to adversely affect both the well-being and health of the worker (Moreno- Jiménez & Báez, 2010). The theoretical models Demand-Control- Social Support (Karasek & Theorell, 1990) and Effort-Reward Imbalance (Fernández-López, Fernández-Fidalgo, & Siegrist, 2005) specify the following psychosocial risk factors related to stress: lack of control, excessive demands, low social support and low rewards in relation to the effort made. The Demand- Control-Social Support model claims that the perception of lack of control, excessive job demands and little support from colleagues and supervisors can produce tension in the worker. On another hand, the Effort-Reward Imbalance model indicates that workers will be more likely to suffer from stress if they do not perceive enough rewards for the effort invested in their work. When workers perceive these psychosocial risk factors, they have

Biomarkers of physical activity and exercise

Biomarkers of physical activity and exercise

Biomarkers are useful tools for assessing and monito- ring health, training status and performance. As there is some controversy in the literature, depending on the pro- cess to be monitored, a combination of biomarkers could be useful. However, controversy exists regarding which parameters are most relevant for monitoring fatigue. The most researched and applied to muscle fatigue are cor- tisol, lactate and IL-6. Also gaining increasingly more importance is the measurement of ammonia, leukocytes and oxidative stress parameters. The biomarkers of muscle fatigue could be a prognostic tool to identifying subjects who are at increased risk of poor adaptation to training. Exercise, in particular, has a major influence on the most widely used inflammatory biomarkers, inclu- ding C-reactive protein and interleukin-6. Additionally to biochemical biomarkers, the measurement of physi- cal fitness components should be included in order to monitor progress and adaptation to training, as fitness is considered one of the most important markers of health.

Perceived quality of life and physical activity in Brazilian older adults

Perceived quality of life and physical activity in Brazilian older adults

ABSTRACT The purpose of this study was to investigate the association between self-perceived quality of life and physical activity in Brazilian older adults. We investigated 199 individuals (117 men and 82 women) aged between 60 to 70 years old, employees of a public university. Physical activity was estimated by the short version of the International Physical Activity Questionnaire (IPAQ). Self-perceived quality of life was assessed using the World Health Organization Quality of Life (WHOQOL-Bref) questionnaire composed of four domains: physical, psychological, social relationship and environment. There was no difference in self-perceived quality of life between men and women. In contrast, quality of life was associated with physical activity even after adjustment for gender, schooling and income. The physical domain presented the strongest association with physical inactivity (Odds Ratio = 2.70, 95% CI 1.87−3.52). Only the environment domain evaluated by WHOQOL-Bref was not associated to physical inactivity. Among the older, improved self-perceived quality of life is positively associated to physical activity.

Self-efficacy for physical activity in adults

Self-efficacy for physical activity in adults

A constituição da crença de autoeficácia se dá por meio da influência de 4 fontes principais. Pajares e Olaz (2008) explicam que a primeira delas é a experiência direta. Esta é a fonte mais influente, pois é a interpretação do resultado do comportamento anterior do sujeito. Em segundo lugar vem as experiências vicárias, ou seja, observar outras pessoas executando as tarefas. Na sequência vem julgamentos verbais que outras pessoas fazem, conhecido por persuasão social e por último os estados emocionais e fisiológicos que propor- cionam informações sobre as crenças de auto- eficácia. Nível de ativação (arousal), fadiga, stress, ansiedade, tensão e dor são manifes- tações que podem alterar a percepção de autoeficácia, pois afetam diretamente o juízo que as pessoas fazem sobre sua própria eficácia.

Importance of physical activity in preventing and coping with stress

Importance of physical activity in preventing and coping with stress

LA PREVENCIÓN DEL ESTRÉS A TRAVÉS DE ACTIVIDAD FÍSICA Varios hallazgos empíricos apoyan el supuesto de que los estilos de afrontamiento emocionales están relacionados con mayores deterioros en la salud de las personas y con comportamientos disfuncionales mientras que las personas que utilizan estilos más activos parecen ser menos propensas a enfermar (Guarino, Emotional sensitivity: a new measure of emotional lability and its moderating role in the stress-illness relationship, 2004; Endler & Parker, 1990; Matthews & Deary, 1998; Matud, 2004; Roger, Jarvis, & Najarian, Detachment an coping: the construction and validation of a new scale for measuring emotion control., 1993; Roger, The mechanics of stress: a model for the relationship between stress, health and personality., 1995; Roy & Steptoe, 1991).

The influence of individual, social and physical environment factors on physical activity in the adult population in Andalusia, Spain

The influence of individual, social and physical environment factors on physical activity in the adult population in Andalusia, Spain

After analysing the different groups of variables separately, and in order to further the analysis, a final multi-variate model was drawn up (Table 4), which incorporates the characteristics of the individuals as well as those of their physical and social environment. All of these variables were significant in the earlier analyses because of their links with sedentariness. By entering these variables into this final model it is apparent that the same trends and similar values continue to exist. This serves to prove the importance of using frameworks which take into account a number of factors which can influence the behaviour of individuals. The most important factors which influence sedentariness are the educational level and social status of individuals (especially in the case of women), the presence of green spaces, and the socio-economic level of the municipality in which they live. The results show evidence of disparities and demonstrate the major influence of the living environment on the behaviour of individuals.

Body image dissatisfaction and its relationship with physical activity and nutritional status in university students

Body image dissatisfaction and its relationship with physical activity and nutritional status in university students

RESUMO O objetivo deste estudo foi verificar a associação da insatisfação com a imagem corporal, com o nível de atividade física e o estado nutricional em universitários recém-ingressos em uma universidade pú- blica brasileira. Participaram do estudo 832 universitários (485 do sexo masculino) com média de 20.1 (desvio padrão = 4.6) anos de idade. A massa corporal e a estatura autorrelatadas foram utilizadas para o cálculo do índice de massa corporal. Os universitários responderam o Body Shape Questionnaire e o International Physical Activity Questionnaire. Utilizou-se o teste exato de Fisher, considerando p < .05. As prevalências de insatisfação com a imagem corporal e inatividade física foram 10.1% e 14.5%, res- pectivamente. Não houve associação significante entre a imagem corporal e o nível de atividade física. A insatisfação com a imagem corporal esteve associada ao estado nutricional para ambos os sexos (p < .05). Conclui-se que os universitários com excesso de peso devem ser motivados a adquirirem um estilo de vida mais saudável, promovendo adequações no seu estado nutricional e também melhorando a sua imagem corporal.

Differences in knee sensorimotor control by physical activity level and sex

Differences in knee sensorimotor control by physical activity level and sex

Knee isometric steadiness was evaluated with the same setup as the MVIC assessment. Each subject was asked to exert knee extensor force to reach a specific target, a trapezoidal figure which represented the 15% of their MVIC (Figure 1B). Subjects were asked to reproduce this paradigm that lasted 20 seconds. To quantify fine muscular control, the coefficient of variation was calculated between the paradigm displayed on the screen and the exerted force of the the subject

View of Physical activity, Cognitive and Psychosocial Functioning in a Preadolescent Sample

Condición Física: Se evaluó la altura mediante un ta- llímetro convencional y la composición corporal a través de un bioimpedanciómetro (Tanita® Body Composition Monitor modelo BC-601). Se efectuó el test de salto hori- zontal para evaluar la fuerza explosiva en los miembros in- feriores (Eurofit, 1993). Asimismo se evaluó la velocidad a través de la prueba 5 x 10 metros (Eurofit, 1993). Además, se analizó el consumo máximo de oxígeno de manera in- directa denominada test de Course Navette (Léger, Mer- cier, Gadoury y Lambert, 1988). Esta prueba consiste en un test incremental de ida y vuelta, sobre una distancia de 20 metros, con un aumento de la velocidad de 0.5 km cada minuto, partiendo de una velocidad inicial de 8.5 km/h. Para el cálculo concreto del consumo de oxígeno se aplicó la fórmula VO2max = 31.025+3.238V-3.248E+0.1536VE (siendo V la velocidad alcanzada en la última etapa com- pletada y E la edad del participante).

Impact of a nutrition and physical activity program in cardiorespiratory, hemodynamic, metabolic and behavior parameters

Impact of a nutrition and physical activity program in cardiorespiratory, hemodynamic, metabolic and behavior parameters

Background: The way by which different types of exercise induce physiological and behavioral changes related to food remains unclear. Objective: to examine if there is a type of exercise or a marker of physical activity level that favors a better compliance with the prescribed diet, a higher eating-related motivation, and a healthier diet composition in overweight and obese subjects. Methods: One hundred and sixty-two (males n=79) overweight and obese subjects, aged 18-50 years, were randomized in four interventions groups during 24 weeks: strength training (S), endurance training (E), combined strength + endurance training (SE) and guideline-based physical activity (PA). All in combination with a 25-30 % caloric restriction diet. All food and beverages consumed by the participants were recorded using a food frequency questionnaire and a “3-day food and drink record” before (pre) and after (post-intervention) the program. Kilocalories consumed in the diet and macronutrient percentages were calculated using the DIAL software. Motivation was evaluated with a questionnaire specifically developed for this study. This questionnaire consisted of 10 questions, rated on a 10- point Likert-type scale. Eight questions were related to diet motivation and two to exercise motivation. Results: No interaction was observed between intervention groups and time and all of them decreased energy intake (p < .001). Carbohydrate and protein intakes increased, and fat intake decreased from pre- to post-intervention without significant interactions with intervention groups, BMI category or gender (p < .001). Diet-related motivation showed a tendency to increase from pre to post-intervention (70.0 ± 0.5 vs 71.0 ± 0.6, p = .053), without significant interactions with intervention groups, BMI category or gender. Regarding motivation to exercise, interaction between gender and time were observed (F (1,146) = 7.452, p = .007), and only women increased

Awareness in healthy habits, physical activity and diabetes during the educational stage

Awareness in healthy habits, physical activity and diabetes during the educational stage

This article has a very clear purpose; To raise awareness among teachers and students about the importance of maintaining some healthy living habits. To do this, a conceptual framework on the consequences of poor diet and the practice of a sedentary life is shown. One of the priorities of the educational system using the Area of Physical Education and games as a support, is to equip students with knowledge, so they could by themselves know what they should and should not do to protect their own bodies. Keywords: World Health Organization, physical activity, school, healthy living habits, food and diabetes.

physical activity, but not about PA patterns and beha- viour. Accelerometers save information about frequen- cy and intensity of PA, but not about type of PA. Both pedometers and accelerometers only save information about lower body movement and reliability about the estimation of energy expenditure is limited. Heart rate monitoring relates intensity to EE, but gives no infor- mation about PA. GPS watches are maybe limited for the assessment of brief higher speed movement and EE. Combined motion sensors share advantages of single devices and are more precise, but activity-specific al- gorithms for the calculation of EE can affect EE results. Most of the devices estimate EE more accurately at li- ght to moderate intensities; underestimation increases at very light and higher intensity activities.

Dairy products intake and physical activity in adults surveyed in a Public Hospital in Buenos Aires

Dairy products intake and physical activity in adults surveyed in a Public Hospital in Buenos Aires

Out of all pathologies related to calcium intake and metabolism, osteoporosis is the one with higher prevalence and impact over morbimortality in our country. Calcium intake and physical activity have independently been associated with an increase in bone mass and a lower bone loss in adults. This study analyses two of the most important environmental factors in the prevention of osteoporosis: dairy foods intake and the habit of physical activity in a population attending a public hospital. A survey on dairy products intake was carried out based on a questionnaire regarding intake frequency and the short format of the International Physical Activity
