Background:Previous studies have indicated that exercise training improves body composition and cardiovascular disease risk factors. The aim of the present study was to investigate the effect of 12 weeks of aerobic, strength and combined training on body composition, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and C-reactive protein (CRP) in sedentary middle-aged men.Methods:Forty-seven male aged 40–60 years voluntarily participated in this study and were divided in four groups: aerobic (n = 12), strength (n = 12), combined (n = 11), and control (n = 12) groups randomly. Body composition, ICAM-1, VCAM-1, and CRP were measured before and after 12 weeks. Data were analyzed using paired t-test and analysis of variance statistical methods.Results:There were significant differences in body weight between aerobic and strength training (P = 0.004) and aerobic and control groups (P = 0.018), body mass index between combined and strength training (P = 0.004) and combined and control groups (P = 0.001), fat percentage between aerobic training and control group (P = 0.017) and combined training and control groups (P = 0.004), and finally, fat-free mass between aerobic and strength training (P = 0.024), aerobic and combined training (P = 0.0001), strength and control groups (P = 0.035), and combined and control groups (P = 0.0001).Conclusions:The results indicated that 12-week workout, 20–60 min/session, 3 days a week of moderate intensity exercise improved body composition, ICAM-1, VCAM-1, and CRP compared to those who did not participate in any training. However, all three types of exercises had small benefits on body composition, ICAM-1, VCAM-1, and CRP in sedentary middle-aged men, and the importance of combined training required further investigations.

El objetivo de este estudio fue examinar la asociación entre actividad física y salud general en profesores de las universidades de ciencias médicas de Fars (Irán). La muestra de este estudio analítico transversal estuvo compuesta por 244 profesores de las universidades de ciencias médicas de Fars (Irán) en 2018. El instrumento de recopilación de datos incluyó un cuestionario de tres secciones: 1) Características demográficas (edad, género e ingresos del hogar). 2) Cuestionario breve para la medición de la actividad física habitual en estudios epidemiológicos. 3) Cuestionario de salud general de Goldberg. El análisis de los datos se realizó con SPSS 16. Los resultados mostraron que no había relación estadística significativa entre la actividad física y las subescalas de salud general en la muestra estudiada. Se recomiendan estudios futuros sobre este tema con muestras más grandes y en otras regiones. The aim of this study was to examine the association between physical activity and general health in faculty members of the Universities of Medical Sciences of Fars (Iran). The sample of this cross-sectional analytical study was composed of 244 faculty members of the Universities of Medical Sciences of Fars (Iran) in 2018. The data collection instrument included a three-section questionnaire: 1) Demographic characteristics (age, gender, and household income). 2) Short questionnaire for the measurement of habitual physical activity in epidemiological studies. 3) Goldberg General Health Questionnaire. Data analysis was performed using SPSS 16. The results showed that there was no significant statistical relationship between physical activity and general health subscales in the sample studied. Future studies about this topic with larger samples and in other regions are recommended.

Motivation is one of the main indices in many theories of learning and psychology. Sports psychologists consider a variety of motivations, including the motivation for progress and achievement, the motivation for competition, the motivation for participation, etc. with specific concepts. Therefore, this study aimed to examine the association between sport motivations with general health in Fars University of medical sciences. This study was a cross sectional-analytical research. The research population consisted of faculty members of Fars University of medical sciences. Sampling was done randomly with a sample size of 244 people. Data were collected using demographic information, sport motivation questionnaire, and general health questionnaire. Descriptive statistics and analytical statistics were used to analyze the data using SPSS-16 software. The results of Pearson correlation test showed that there was a significant correlation between general health and sport motivation (P = 0.001, r = -0.252); among the components of sport motivation, only physical recovery dimensions, competition, weight control, and health do not have a significant correlation with the general health. The results of this study indicated an association between general health and sport motivation and some of its components in the study population. Therefore, the applying methods for increasing the athletic motivation to achieve the desired levels of general health and its components by modeling the results can be useful for planners and managers of human resources in universities.

Introduction:Growth hormone is a strong metabolic factor that facilitates growth and hypertrophy and increase transfer of amino acids into the cells. Exercise is a potent stimulant of growth hormone secretion. If it is regularly done, the rate of hormone secretion increases in 24 hours. In previous studies, the role of championship training has been little considered. So, given the importance of the abovementioned hormone in puberty period and the necessity of participation in the championship, this study aimed to investigate the relationship between physical activity in championship level and changes of this hormone. Material and Methods:12 male adolescent athletes Estahban were chosen as the subjects. Finally, eight of them (mean age= 14.44, height= 1.56 m and weight= 46.3 kg) participated in the study. Blood samples were collected before exercise, after 10 weeks of submaximal exercise, and at the end of 3 weeks of maximal exercise. ,. The samples were collected 12 hours after the last training. Results:The results indicated that submaximal exercise had no significant effect on baseline growth hormone and blood sugar (p=0.446, p=0.289). But maximal training caused a significant increase in the baseline growth hormone and blood sugar (p=0.048, p=0.045). Conclusion:According to the results, exercise intensity below the maximum for male adolescents has a significant impact on the amount of baseline growth hormone whereas maximal exercise increases the amount of baseline growth hormone significantly. Increased growth hormone leads to increased protein synthesis, increased bone, increased muscle size and improved athletic performance.
