Many studies on pilates have shown that these exercises positively affect the endurance of core muscles, mental health, and quality of life in healthy individuals when applied face-to-face.

In a few recent studies, the effects of online pilates training have been examined and shown to be effective on core endurance, depression, and quality of life. In the results of these studies, it has been emphasized that it is necessary to compare whether online pilates training is as practical as face-to-face pilates training. For this reason, the investigators thought that randomized controlled studies investigating the effects of online and face-to-face pilates methods in healthy individuals are needed. The investigators planned a randomized controlled study investigating the impact of online pilates and face-to-face pilates methods. The study aims to examine and compare the effects of online pilates and face-to-face pilates methods on core muscle endurance, depression, and quality of life in healthy individuals.

An experienced physiotherapist blind will evaluate participants by randomization at the start of the study and eight weeks later. The group participants belong to will not be disclosed to the participants until the end of the first assessment. Individuals who complete the initial evaluation will be randomly assigned to the online pilates group (OPG) or face-to-face pilates group (FPG) using a computer program. Both online and face-to-face applications will be carried out under the supervision of a physiotherapist with 11 years of experience.

Participants included in the study will be evaluated with data collection forms filled twice, before and after the training programs. The participants' demographic information (age, body weight, height, body mass index) will be recorded.

Statistical analysis will be performed using SPSS software, version 21 (SPSS Inc. Chicago, IL, USA). The normal distribution of the variables will be determined using histograms, probability plots, and the Shapiro-Wilk test. Due to the abnormal distribution, the median and interquartile range (IQR) will be used for descriptive statistics. A Mann-Whitney U test will be used to compare baseline and vary values between groups. The Wilcoxon test will compare baseline values within the group to values after six weeks. The significance level will be set-top < 0.05 for all analyses. Effect sizes will be evaluated according to Cohen's d standards within pre-post differences. Effect size results will be interpreted as small (≥ 0.2), moderate (≥ 0.5), or large (≥ 0.8) according to the guidelines.

Inclusion Criteria:

• 25-40 years of age.
• Voluntarily participate in research to accept

Exclusion Criteria:

• Any cardiovascular, orthopedic, visual, hearing, and perception problems that may affect the results of the research.
• Participating in other exercises or physiotherapy programs during the past 6 months.

Participants were evaluated at the beginning of the study and 8 weeks later by an experienced physical therapist blind to randomization. The group participants belonged to was not disclosed to the participants from the initial assessment to the end.
