ABSTRACT
Background and Aim: resistance training exercise is one of the most common methods in fitness programs and health programs for athletes and therapists. Manipulation of every variable of training, such as rest intervals changes the adaptation and lead to the acquisition of more strength, higher endurance or biochemical changes in the body or cells. The purpose of this study was to determine the effects of two resistance exercise [RE] protocols with different rest intervals [RI] on serum homocysteine and CRP concentrations
Material and Methods: this study included sedentary men between 19-28years of age who were randomly divided into 3 groups: two experimental groups including RE with RI of 90 [n=10] seconds and RE with RI of 180 seconds [n=10], and a control group [n=10]. Exercise protocol included 8 exercises with intensity of 50% of 1RM in the first session and 85% of 1RM in the last session. The participants' weight, body fat percentage and body mass index were measured before and after intervention. In addition fasting homocysteine and CRP levels were measured by use of ELISA method before and after the exercise program for the 3 groups. ANOVA test was used to analyze the data. We used Benferoni statistical test in order to determine and arrange the mean differences within every group
Results: the results showed that resistance training for eight weeks with different RI can lead to significant decrease in the levels of homocysteine and CRP in healthy sedentary men
Conclusion: circuit resistance training with different RI decreased the serum levels of homocysteine and CRP in the healthy sedentary men. Therefore, these exercises may decrease the risk of cardiovascular diseases
ABSTRACT
One of the main parts of the military exercises is to prepare physically training. There are not any detailed knowledge of the effectiveness of training programs on psychological and fitness indicators of the officer students till now. This study was investigated the influence of the 12-week military's training on fitness, body mass index, mental health and mood officer students. A quasi-experimental trial was conducted in this field. Ninety student officers from one of the military universities, Entrance 2010, were selected. Seventy individuals in the experimental group and 20 subjects in control group were recruited. Aerobic performance, agility, muscular endurance and body mass index were measured in the early period [first week], medium term [sixth week] and at the end of the course [twelfth week]. Mental health and temperament scales of the questionnaire were assessed by Goldberg [GHQ-28] questionnaire and Brooms respectively. A course of military selective training was a significant effect on the aerobic performance [the 1600 m run test time], agility performance [time of test 4x9 m run], and muscular endurance performance [test scores of sit up and pull up] on the experimental group [p=0.000]. While there was no significant effect into their body mass index, mental health and mood scores. The findings were based on the physical performance indicators in the combination with behavioral and physical indicators as more sensitive to military exercises. And the development of fitness indicators and a negative impact on the behavioral indicators of this exercise is beneficial for the officer students
