About

The aim of this study is to investigate the effectiveness of Pilates-based exercises on cognitive functions in comparison with aerobic exercises.

Individuals in the 4-weeks study will be divided into two groups using the Graphpad website: Clinical Pilates exercise group (Group 1), aerobic exercise group (Group 2). The sample size for each group was calculated as 24 people. Considering the possibility of %10 drops, 27 individuals will be included in each group and a total of 54 cases in the study. First, the socio-demographic information of the participants will be collected with a prepared form. Individuals will be assessed by the International Physical Activity Questionnaire-Short Form, Nelson Speed of Movement Test, Verbal Fluency Test and Stroop Test at pre-study,end of the first session and end of the study (4th week). Participants in control will be given will keep an activity lo to check their physical activity levels. SPSS package programme will be used in the analysis of the data and p<0.05 will be considered significant.

Full description

Modern society adapts to the sedentary lifestyle. This global trend is a major threat to public health because inactivity is the leading cause of global mortality. In addition, low physical activity is related to risk of hypertension, obesity, type II diabetes, cancer, and many other chronic diseases.

There is evidence that regular physical activity contributes to primary and secondary prevention of various chronic diseases. It is claimed that physical activity can also affect cognitive functions, reduce dementia risk in addition to health benefits. However, studies investigating the effects on cognitive functions such as attention, learning and memory are limited.

As a method of physical activity, the effects of aerobic and resistive exercises on cognitive functions were generally investigated in the research.Pilates based exercises commonly used in recent studies and its effectiveness investigated in various fields are also a physical activity method with six principles including concentration, control, centering, flowing movement, precision and breathing. Pilates-based exercises that require mentally focusing on the targeted body region, develop body-mind connection, aim to increase the quality of movement by neuromuscular methods with directing attention to the moving part of body segment, appear to be a way to positively affect cognitive functions.

The aim of this study is to investigate the effectiveness of Pilates-based exercises on cognitive functions in comparison with aerobic exercises.

Individuals in the 4-weeks study will be divided into two groups using the Graphpad website: Clinical Pilates exercise group (Group 1), aerobic exercise group (Group 2). The Power and Sample Size version 3.1.2 (PS) programme was used to calculate the sample size. Because of the lack of "minimal clinical important difference" value for the Stroop test in the literature while the sample size calculation, the standard deviation value was set to 60 (σ) (derived from a similar study), the change in the means (δ) was set as 50 in the formula (power 80%, α 0.05). The sample size for each group was calculated as 24 people. Considering the possibility of %10 drops, 27 individuals will be included in each group and a total of 54 cases in the study. Individuals will be enrolled according to the inclusion criteria.

First, the socio-demographic information of the participants will be collected with a prepared form. Individuals will be assessed by the International Physical Activity Questionnaire-Short Form, Nelson Speed of Movement Test, Verbal Fluency Test and Stroop Test at pre-study and 4th week.

SPSS statistical program will be used for statistical analysis. The Shapiro Wilk test will be performed to determine the normal distribution suitability of the data. The difference between the continuous variables in the groups will be compared with the Independent T test. Paired Simple T-Test will be used to evaluate changes in each group before and after the program. In all analyzes p<0.05 will be considered statistically significant.

52 participants in 2 patient groups

Clinic Pilates Group

Experimental group

Description:

Initial assessments of participants were made and they were taught key components of the Clinical Pilates exercises. Exercises were administered for 4 weeks, 3 days/week, 40-50 minutes/session under the supervision of a physiotherapist. Groups of 9-10 people with similar physical characteristics and fitness level for session times were created. The sessions were started with level 1 exercises requiring more support and less control. Each exercise was repeated 8-10 times; as the physical level of the participants increased, exercises progressed towards level 3 exercises requiring more attention, concentration and control. Each session consisted of an average of 10 minutes warm-up, 20 to 30 minutes of matt and 10 minutes cooling of of Clinical Pilates exercises.

Other: Clinic Pilates Group

Aerobic Exercise Group

Experimental group

Description:

Initial assessments of participants were made before the first session. Using an elliptical bicycle or bicycle, or treadmill under the supervision of a physiotherapist, a total of 150 minutes moderate intensity (50-70% of maximal heart rate (HRmax)) aerobic exercise in accordance with the World Health Organization's guideline was applied, 3 days/week (50 mins/session) or 5 days/week (30 mins /session) for 4 weeks. The instruments to be used for the exercises were chosen according to the preference of the individual. HRmax was calculated using the "220-years". For example; at the age of 20 years, the target heart rate was determined as 100-140 beats/min for moderate physical activity in a person with HRmax 200 beats/min.
