[Effect of olive oil on IL-6, TNF-alpha and cortisol hormone levels in active girls after one session of an exhaustive exercise: a brief report]

The aim of this research was to determine the effect of olive oil on interleukin 6 [IL-6], Tumor necrosis factor a [TNF-a] and cortisol hormone in response to exhaustive exercise in active girls. Twenty four healthy girls aged 21-27 years participated in this study. The subjects were randomly assigned to supplement [n=12] and control [n=12] groups. Supplemented group was fed with olive oil for one week. Blood samples were taken in a week before of exercise test, before exercise, immediately and 1 hour after the end of the exercise. There was a significant increase in the level of cortisol, IL-6 and TNF-alpha in the supplement and control groups in compared with a week before of exercise test and before exercise test [P

influence of nine-week intensive aerobic exercises, calcium and vitamin D supplementation on the metabolic response of bone formation biomarkers

The purpose of the study is to analyze the impact of 9-week intensive aerobic exercises and the calcium and vitamin D supplement intake on the indicators which show bone formation in young women. 44 non-athletic women in their thirties [27.18 +/- 3.65] were studied randomly in four groups: 1] Exercise, 2] Calcium and vitamin D supplement, 3] Exercise and supplement, and 4] control. The subjects exercised three sessions a week for 9 weeks, each session lasted 30-45 minutes. The blood and urinary samples were collected from the experimental and control groups while they fasted either before or after exercise program. The concentration of alkaline phosphates and procollagen I, C terminal [PICP] had been measured using DGKC and HPLC techniques, respectively. The collected data had been combined with the statistical t-tests and were analyzed by ANCOVA [p<0.05]. Significant increasing of ALP and PICP was observed in exercise group [p=0.001] and exercise + supplement group [p=0.001]. In supplement group, alkaline phosphate and procollagen type 1, C-terminal show a significant decrease [p=0.001], while the difference was not significant in the control group. Generally, the research results show that the intensive aerobic exercise and adequate intake of calcium and vitamin D affect positively the bone mass development during youth and they reduce fracture risk; however, such claim needs further investigations
