Abstract
Abstract Aim. The purpose of this study was to compare the effects of concentric and eccentric isokinetic contractions and subsequent recovery period on the hemodynamic factors in men. Background. Nowadays, with advances in technology and producing the innovative training equipment, performing different resistance exercise protocols for improving the muscular and cardiovascular function is possible. Method. In this quasi-experimental study, ten healthy male subjects were volunteered to participate in the study and performed two protocols of Concentric/Concentric (CON/CON) and Eccentric/Eccentric (ECC/ECC) isokinetic contractions (4 sets, 10 repetitions, 60˚/S) including knee flexion and extension with dominant leg, in two separate sessions. Hemodynamic factors were measured before, immediately and 30 min after exercise. Findings. Statistical analyses of data showed that hemodynamic parameters increased in response to both isokinetic contractions (p<0.001) and decreased following recovery period. Moreover, Systolic Blood Pressure (SBP), Mean Arterial Pressure (MAP) and Rate Pressure Product (RPP) responses to two types of contractions (CON/CON and ECC/ECC) were significantly different (p<0.05). Regardless of contraction type, the Rate of Perceived Exertion (RPE) increased significantly from 1st set to 4th set though, these changes were not significantly different between two protocols (p>0.05). Conclusion. Hemodynamic changes in response to CON/CON was higher than ECC/ECC protocol which shows that the acute ECC/ECC is safer than CON/CON protocol.

Abstract
Aim. This study aimed to determine the effect of health promoting lifestyle training on vitality, psychological well-being and blood pressure of women with cardiovascular disease.
Background. Women with cardiovascular disease have many problems in physical and mental health and one of the effective methods in this field is health promoting lifestyle training method.
Method. This was a quasi-experimental study with pretest-posttest and follow-up design with control group. The study population consisted of women with cardiovascular disease referred to Rajaie Cardiovascular Medical and Research Center in Tehran, Iran, in 2019. The sample consisted of 40 women who were selected by purposeful sampling method and randomly allocated into experimental and control group. The experimental group received eight 75-minute educational session (one session per week) on health promoting lifestyle and the control group placed on the waiting list for training. Data were collected using questionnaires vitality and psychological well-being and sphygmomanometer and were analyzed by Chi-square test, independent t-test, repeated measures and Bonferroni post-hoc test in SPSS Version 19.
Findings. In the pretest stage, there was no statically significant difference between the experimental and control group in terms of vitality, psychological well-being and blood pressure, but in the posttest and follow-up stages, there was found a statically significant difference in terms of all three variables of vitality, psychological well-being and blood pressure, meaning that health promoting lifestyle training method led to increase vitality and psychological well-being and decrease blood pressure of women with cardiovascular disease. This effect continued in follow-up stage.
Conclusion. The method of health promoting lifestyle training led to improve the vitality, psychological well-being and blood pressure of women with cardiovascular disease. It is recommended that health care providers use health promoting lifestyle training method along with other educational and therapeutic modalities to improve the health-related components.

Abstract
Aim. The aim of this study was to compare the effect of two high intensity interval training (HIIT) protocol on plasma levels of adiponectin, leptin and hypertension in overweight nurses.
Background. Cardiovascular disease, as a chronic and debilitating physical condition, is one of the most common causes of death worldwide and can affect the health of individuals, especially nurses who are exposed to a variety of diseases and it is necessary to identify variables related to health in these group.
Method. This was a clinical trial in which 27 nurses (mean age 25.81±0.6 years, mean height 158.01±7.6 cm and mean weight 69.41±0.25 kg) were selected and randomly divided into three groups of high intensity interval training type 1 (8 seconds of fast running and 12 seconds of active recycling), high intensity interval training type 2 (40-meter sweep test with maximum speed), and control group. High intensity interval training type 1 was performed for four weeks, three sessions per week, each session lasted 6-9 minutes with more than 90% of maximum heart rate. High intensity interval training type 2 was performed for four weeks, three sessions per week, with more than 90% of the maximum heart rate. The control group did not participate in any training program.
Findings. The study showed that HIIT type 1 and type 2 had a statistically significant effect on reducing plasma leptin levels, systolic and diastolic blood pressure and increasing plasma adiponectin concentration in nurses. Both training methods improved health indicators (adiponectin, leptin and systolic and diastolic blood pressure), but HIIT type 1 training caused more control and regulation of these indicators compared with compared to HIIT type 2.
Conclusion. There is a significant difference between type 1 HIIT exercise, type 2 HIIT exercise and control in research variables (adiponectin, leptin and blood pressure) in nurses.
