Comparador activo: Aerobic Exercise Group
Aerobic Exercise Training
|
Participants in the aerobic exercise group will undergo an 8-week supervised aerobic exercise program on a cycle ergometer, performed twice per week.
Each session will last approximately 30-45 minutes and will include a 5-minute low-intensity warm-up and a 5-minute cool-down period.
Exercise intensity will be set at a moderate level according to the Karvonen method.
The main exercise duration will be progressively increased throughout the intervention period: 20 minutes during weeks 1-2, 25 minutes during weeks 3-4, 30 minutes during weeks 5-6, and 35 minutes during weeks 7-8.
Participants' heart rate will be monitored during exercise sessions, and perceived exertion will be assessed using the Borg Rating of Perceived Exertion Scale.In addition, all participants will be instructed to perform resistance exercises once per week.
The exercises will target the upper extremity, lower extremity, and core muscles and will consist of three different exercises.

|
Experimental: Exercise Snacks Group
Exercise Snacking
|
The exercises will be performed by participants at home and supervised by the researcher.
Since progression of each exercise will be implemented every two weeks, participants will be scheduled to attend the clinic every two weeks, where the exercises will be demonstrated.
Each session will consist of six different exercises (squat, heel raises, marching in place, jumping jacks, upright row, and chest press).
Each exercise will be performed for 1 minute, followed by a 1-minute seated rest interval.
Thus, each session will last approximately 12 minutes.
Exercise progression will be applied every two weeks for each exercise.
During the sessions, participants will monitor their heart rate and oxygen saturation.
An oxygen saturation level below 90% will be defined as the exercise termination criterion.
Participants will be provided with a daily logbook to record completion of exercise snacking sessions.
