Brief Summary

Detailed Description

The effect of a weight-loss diet on body composition in women reformer pilates for 12 weeks was compared in this study. It compares dietary habits and macro and micronutrient intakes in subjects with and without a weight-loss diet at the start and end of the study.

A total of 49 women (18 years old) were randomly assigned to one of two groups: control (CG: reformer pilates; n=23) or study (SG: reformer pilates + weight-loss diet; n=26). Subjects in both groups did pilates for 45 minutes three times a week for a total of 12 weeks. At the start and end of the study, their body weight (kg), waist circumference (cm), hip circumference (cm), neck circumference (cm), mid-upper arm circumference (cm), and body composition \[body fat (% ), body water (% ), body muscle (% )\] were all measured. Their waist/height ratio and body mass index (kg/m2) were also measured at the start and end of the study. All subjects' dietary habits were questioned, their 24-hour retrospective food consumption was recorded, and their physical activity levels were assessed using the International Physical Activity Questionnaire (Short Form).

Arm && Interventions

Group	Intervention	Description
Study Group	Dietary intervention	The study group does reformer pilates for 45 minutes 3 days a week. The intensity of the workouts was gradually increased. Warm-up (10 minutes), main Pilates training activity (25 minutes), and cool-down (10 minutes) were the three parts of each session (10 minutes). In addition to pilates, the women in the SG followed a personalized weight loss diet. In accordance with Turkey Dietary Guidelines, these diet plans were designed to provide 45-60% of energy from carbohydrates, 10-20% from protein, and 20-35 percent from fat.

Primary Outcome Measures

Name	Time	Method
Physical activity levels	12 weeks	Their physical activity levels were evaluated through the International Physical Activity Questionnaire (IPAQ Short Form). This form had seven questions and asked about the amount of time spent sitting, walking, moderate, and vigorous activities. The total score accounted for the duration (minutes) and frequency (days) of the activities completed. Physical inactivity (600 MET -min/week), low physical activity (600-3000 MET -min/week), and adequate physical activity (with health benefits) (\>3000 MET -min/week) were defined.
Food consumption	12 weeks	Their 24-hour retrospective food consumption were taken
Change in anthropometric measurements	12 weeks	At the start and end of the study, their body weight (kg), waist circumference (cm), hip circumference (cm), neck circumference (cm) and mid-upper arm circumference (cm) were all measured. These measurements are expected to change according to the beginning of the study.
Change in body composition	12 weeks	At the start and end of the study, their body fat (%), body water (%), body muscle (%) were all measured. Their waist-to-height ratio and body mass index (kg/m2) were also measured at the beginning and end of the study. These measurements are expected to change according to the beginning of the study.
