BRIEF TEXT


… [1-11] As a resistance exercise, Pilates is a sport activity model to prevent and treat diseases such as osteoporosis and postural abnormalities [12, 13].

Most studies have used aerobic exercises to reduce weight and fat. The obese persons do aerobic activities with difficulty, if they are possible for them.

The aim of this study was to study the effects of 8-week Pilates on cortisol and lipid profile in the obese women.

This is an experimental study.

40±5 year-old non-athlete obese women of Najaf Abad (Isfahan; Iran) with more than 30kg BMI were studied.

20 women were selected, using random method.

Based on the similar studies, the sample size was estimated 20 persons. Inclusion criteria were no drug, no smoking, no surgery, no athletic activity, and no special diseases such as thyroid, diabetes, and joint’s pain. The persons were divided into two groups, including Pilates (n=10) and control (n=10). The samples’ diet was controlled by 24-hour Recall Questionnaire (Shahid Beheshti University). The samples’ weight and height were measured, using a scale and a stadiometer (Seca; Germany). BMI was computed through dividing weight (Kg) by the square of height (m²). Fat distribution was measured through waist and hip measurements and waist to hip ratios. Blood sampling was done in two stages, including 24 hours before the first exercise session (pretest) and 48 hours after the last exercise session (at the end of the 8th week) after night breakfast and at 8 a.m. from the left anterior vein. The samples’ feast period was at least 12 hours, from 8 p.m. to 8 a.m. The samples of control group were asked to have no sport activity or long term walking during 48 hours from the end of the exercise course. Plasma triglyceride levels were measured, using Calorimeter-Enzymes Method by a kit (Pars Azmoon; Iran). HDL was measured through photometry method and by a kit (Pars Azmoon; Iran). The equation “LDL=TC-HDL-TG/0.5” was used to compute LDL. Cortisol was assessed through Eliza method and by DE-SIV2930 kit (Human Wiesbadwn; Germany). Data was analyzed, using SPSS 19 software and Descriptive and Deductive Statistics (to investigate the samples’ characteristics). Correlative T and Independent T tests were used for intragroup and intergroup comparisons, respectively.

8-week Pilates exercises led to significant reductions in weight, BMI, cholesterol, and LDL in Pilates group and led to a significant increase in cortisol (Table 1). There were significant differences in BMI and cortisol between the groups after 8-wek Pilates exercises. There was no significant difference in mean values of other parameters between the groups.

10-week Pilates leads to significant reductions in weight and BMI of the extra-weight women, which is a result consistent with the present results. Nevertheless, there is a significant reduction in waist-to-hip ratio, which is not consistent with the present result about waist [13]. … [14-17] 4-week Pilates exercises result in significant reductions in weight and BMI of 11-year old obese girls, which is consistent with the present results [18]. 8-week Pilates leads to significant reductions in cholesterol and LDL, and leads to no change in HDL and triglyceride as well. There was no significant change in the indices in control group. 8-week resistance trainings lead to significant reductions in cholesterol and LDL without any change in other indices in the obese men [16], which is consistent with the present results. 8-week resistance exercises, aerobic exercises, and no-exercise lead to a reduction in triglyceride in resistance and aerobic groups [15], which is not consistent with the present results. There was a significant increase in cortisol in Pilates group. 10-week parallel, strength, and endurance exercises lead to a significant increase in cortisol in endurance group in the untrained male students [17], which is consistent with the present results. … [19-26] 2-week high resistance exercises lead to a significant increase in the concentration of the salivary cortisol hormone in the bodybuilder male athletes [27], which is consistent with the present results of Pilates group. … [28-32]

A long-term study or a study with more repetition per week should be done. Circadian rhythm of cortisol should be studied. The effects of Pilates on the density of the lipoprotein particles of plasma should be investigated.

Menstruation control of the samples was difficult. No precise control on the samples’ activities out of the study, their diet, and their mental pressure during sampling were of the limits for the present study.

Pilates exercises lead to reductions in weight, BMI, cholesterol, and LDL, and a higher cortisol.

All participants are appreciated.
