In obese individuals, increased adipose tissue and systemic inflammation play a key role in the development of cardiometabolic diseases, pulmonary system dysfunction, and many respiratory diseases. Existing research has demonstrated beneficial clinical outcomes of inspiratory muscle training or combined aerobic and resistance exercise training in obese individuals. However, this focused on the isolated effects of exercise on obesity. In the current literature, no study is evaluating the effectiveness of functional inspiratory muscle training in obese individuals.
This study aims to investigate the effects of functional inspiratory muscle training on body composition, cardiometabolic markers, functional capacity, respiratory function, respiratory muscle strength, and respiratory muscle performance in obese individuals.
Obesity is characterized by increased adipose tissue and systemic inflammation that play a key role in the development of non-communicable chronic diseases. It is well known that individuals with obesity have decreased exercise capacity and muscle weakness in both peripheral and respiratory muscles.
Exercise training is recommended in addition to healthy dietary habits in managing obesity. Current literature demonstrated beneficial clinical outcomes of isolated inspiratory muscle training or combined aerobic and resistance exercise training in obese individuals.
Functional inspiratory muscle training is a method that combines both aerobic exercise and inspiratory muscle training. In the current literature, no study is evaluating the effectiveness of functional inspiratory muscle training in obese individuals. The aim of this study is to investigate the effect of functional inspiratory muscle training on body composition, cardiometabolic markers, functional capacity, respiratory function, respiratory muscle strength and respiratory muscle performance in obese individuals.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Aerobic and Resistive Exercise Training | Active Comparator | The exercise program will start with a 5-10 minute warm-up and end with a 5-10 minute cool down. Aerobic exercise is planned at 60-85% of Maximum Heart Rate on the bike for 30-40 minutes. Resistive exercise program, covering all major major muscle groups; The upper body (pectoralis, latissimus dorsi, rotator cuff muscles, deltoid, biceps, triceps), abdominal muscles and lower extremities (quadriceps, hamstring, gastrosoleus) will be exercised to strengthen. For upper body muscles, abdominal muscles and lower extremity muscles, 1-3 sets of 10-15 repetitions will be planned as 40-70% of 1 maximum repetition (1RM). |
|
| Functional Inspiratory Muscle Training Group in obese individuals: | Experimental | Inspiratory muscle training will be applied simultaneously with aerobic exercise. This program will create the functional IMT. The exercise program will start with a 5-10 minute warm-up and cool down. Aerobic exercise is planned at 60-85% of MHR on the bike for 30-40 minutes, progress will be achieved. Participants will first work with bicycle ergometry and then continue with IMT in the same session for the first three weeks. The intensity of IMT exercise will be set at 40-60% of MIP. After 10 consecutive breathing cycles, participants will be asked to perform 3-4 breath checks. Resistive exercise program, covering all major muscle groups; The upper body (pectoralis, latissimus dorsi, rotator cuff muscles, deltoid, biceps, triceps), abdominal muscles and lower extremities (quadriceps, hamstring, gastrosoleus) will be exercised to strengthen. For upper body muscles, abdominal muscles and lower extremity muscles, 1-3 sets of 10-15 repetitions will be planned as 40-70% of 1RM. |

| Comorbidity Assessment | "Charlson Comorbidity Index" (CMI) will be used to determine the comorbidity levels of obese individuals. The index, which consists of nineteen comorbid diagnosis groups, is a valid method for evaluating chronic diseases and measuring their relationship with mortality. All CMI scores are scored between 0-37. According to the results, 3 levels of comorbidity are defined: low (0), medium (1-2) and high (3+). |

| Aerobic+Resistive Exercise Traning | Other | Aerobic exercise is planned at 60-85% of the Maximum Heart Rate on a cycle ergometer for 30-40 minutes. Resistive exercise will cover all major muscle groups. The upper body (pectoralis, latissimus dorsi, rotator cuff muscles, deltoid, biceps, triceps), abdominal muscles, and lower extremities (quadriceps, hamstring, gastrosoleus) will be exercised to strengthen. For upper body, abdominal, and lower extremity muscles, 1-3 sets of 10-15 repetitions will be planned as 40-70% of 1 maximum repetition (1RM). |

| Physical Activity Assessment | Step Count Measurement: Daily step count will be monitored to determine the physical activity level of the participants. Step count will be assessed with a wearable activity monitor, a portable, easy-to-use tool that can measure objectively (Huawei Watch Fit Special Edition). With its six-axis sensor, the device records the user's physical activity style information in its temporary memory throughout the duration of use. Participants will be asked to wear the activity monitor on their left wrist throughout and only remove it during bathing.
