Prediabetics is a condition where blood sugar levels are normal but not yet high enough to be diagnosed as type 2 diabetes. This phase offers a crucial point for timely intervention to delay or prevent type 2 diabetes. The objective of the study will be to find the effects of high intensity interval and continuous endurance training on glycemic control, BMI, Vo2 Max, pulmonary function and physical activity among prediabetic patients. Study design will be randomized control trial. Total 80 participants will be enrolled in study. The data will be collected from faculty of Riphah International University, Lahore. The study will be completed within 8 months after approval of synopsis. A simple random sampling will be used to assign the groups; group A and group B. Group A will be assigned high intensity interval training and group B will be assigned to continuous training.
Sedentary lifestyle (Individuals reporting minimal structured physical activity e.g., <30 minutes of exercise per week) .
Stable Medical Condition (No history of significant cardiovascular events, uncontrolled hypertension, or other major comorbidities).
Stable Body Weight (Stable body weight with changes less than 3 kg in the past 6 months).
uncontrolled hypertension
history of heart disease
myocardial infarction
stroke
Parallel
High-Intensity Interval Training
Behavioral5 minutes warm up including walk * 30s fast stairs climbing * 60s slow walk down * Repeat 5 to 6 rounds * 5 minute stretching or slow walk (cool down)
Continuous Endurance Training
Behavioral5 to 10 minute walking (warm up ) * 25 to 30minutes at 60 to 70 %continuous training * Continuous walk for 15 to 20 minutes. * 5 to 10 minutes stretching (cool down)
fasting blood glucose
Participants were instructed to fast overnight for 8 to 12 hours. FBG was measured using an automated glucose analyzer
Forced Vital Capacity
Spirometry using devices like a digital spirometry will be used. Forced Vital Capacity (FVC) will be measured in liters (L) using spirometry. FVC represents the maximum volume of air that can be forcefully exhaled after a maximal inspiration.
Forced Expiratory Volume in One Second
Forced Expiratory Volume in One Second (FEV₁) will be measured in liters (L) using spirometry. FEV₁ represents the volume of air exhaled during the first second of a forced expiratory maneuver.
FEV₁/FVC ratio
The FEV₁/FVC ratio will be expressed as a percentage (%) and calculated from spirometric measurements to assess the degree of airflow limitation.
Body mass index (BMI)
Participants weight was measured using a calibrated digital scale with minimal clothing and no shoes height was measured using a wall mounted stadiometer with participants standing upright
IPAQ (short form) questionnaire
International physical activity questionnaire is applicable for survey among 18 to 65 years to Assess the level of physical activity along different countries. It is developed in 2 Versions; first is long version (27 items), and the second is the short version (7 items). We will use IPAQ short version which consists of job, transport, domestic, and leisure time physical activity domains. Moderate and high-intensity walking and sitting time activities are addressed in this questionnaire
Maximal Oxygen Uptake (VO₂max)
In this research VO2 Max will be measured through a submaximal 6 mint walk test
