Group A will be recieving elliptical exercise (Steady state moderate intensity protocol on elliptical trainer, interval elliptical training)

Group B will be recieving swiss ball exercises (Seated arm raises with light weights and bands, seated torso rotation,seated bouncing,arm circles and punches while sitting,diaphragmatic breathing with ball hug, wall squat with swiss ball support).

Participants allocated to the this group will undergo a structured aerobic training program using an elliptical trainer. The exercise prescription will adhere to the FITT framework as follows: frequency of five sessions per week, moderate intensity (targeting approximately 50-70% of heart rate reserve or corresponding Rating of Perceived Exertion of 12-14 on the Borg scale), and duration of 30 minutes per session. Each session will be supervised and will include appropriate warm-up and cool-down periods according to standard cardiac rehabilitation protocols. The intervention will be delivered consistently throughout the study period using an elliptical exercise modality.

6-Minute Walk Test (6MWT) is a practical and widely used assessment tool to measure exercise capacity and functional status in individuals with various health conditions. To perform the test, a flat, straight corridor with a measured distance is required. The individual is instructed to walk at their own pace, aiming to cover as much distance as possible within the 6-minute time frame. They can slow down, stop, or rest if needed, but the timer continues to run. The test administrator records the total distance walked, as well as any symptoms, such as shortness of breath or fatigue. The 6MWT is a valuable tool for assessing exercise capacity improvement, as it reflects an individual's ability to perform daily activities and can be used to monitor changes in functional status over time or in response to interventions, such as exercise training or rehabilitation programs. By tracking changes in distance walked, healthcare providers can evaluate the effectiveness of treatment plan.

A pulse oximeter, often referred to as a pulse ox, is a small, non-invasive medical device that clips onto a fingertip, toe, or earlobe to measure two critical health metrics: oxygen saturation (SpO2) and heart rate. Oxygen saturation indicates the percentage of hemoglobin in the blood that is carrying oxygen, while heart rate measures the number of heart beats per minute (bpm). To use a pulse oximeter for measuring heart rate, simply place the device on the chosen site, ensuring a snug fit, and turn it on. After a few seconds, the device will display both your oxygen saturation level and heart rate. It's essential to remain still during measurement to ensure accuracy, as movement can interfere with the readings. A pulse oximeter is a valuable tool for monitoring heart rate, especially for individuals with heart conditions, respiratory issues, or those engaging in high-altitude activities. By providing quick and reliable readings, it helps users track their heart rate in real-time.

The Modified Borg Scale is a widely used tool to assess the severity of dyspnea (shortness of breath) in patients. It is a simple, self-reported scale that asks patients to rate the intensity of their breathlessness from 0 to 10, with 0 indicating "no breathlessness" and 10 indicating "maximal breathlessness." To use the Modified Borg Scale, patients are asked to select a number that corresponds to the severity of their dyspnea, with descriptors provided for each level of severity, such as "slight" (1-2), "moderate" (3-4), "severe" (5-6), and "very severe" (7-10). This scale helps healthcare providers quantify the impact of dyspnea on patients' daily lives and monitor changes in symptoms over time or in response to treatment. By regularly assessing dyspnea using the Modified Borg Scale, healthcare providers can tailor interventions to meet individual patient needs, evaluate the effectiveness of treatments, and improve patient outcomes.
