Effect of High Intensity Interval Training on Strength, Endurance and Flexibility

Strength and endurance are essential components for physical fitness of any individual. High intensity interval training provides time efficient benefits for strength and endurance training. Physical Therapy professionals and students need physical fitness for effective clinical performance of patients. There is limited research regarding physical performance of physical therapists itself

About this study

Physical fitness is defined as capacity of doing physical activity using muscular efforts, resulting in energy expenditure. It is dependent upon body composition, muscle strength, endurance and flexibility of person. Pre assessment of strength, endurance and flexibility among physical therapy students will measure their physical fitness and findings from High intensity interval training (HIIT) will help further clinicians for designing fitness program to enhance physical abilities of future physical therapists. This study will address the gap by finding effects of HIIT that would help to improve fitness level of physical therapy students and influence exercise prescription.

Objective: To determine effects of high intensity interval training versus conservative treatment for strength, endurance and flexibility of undergraduate physical therapy students

Treatment and study plan

High Intensity Interval Training

Other

High intensity interval training provides time efficient benefits for strength and endurance training. It comprises of high burst training with rest periods. For experimental group HIIT training will be applied comprising of burpees, squats, arm walking and lunges. The exercise will be given 3 times/ week for 4 weeks. For standardization experimental group will receive 10 minutes of warm up and cool down period comprising of stretching exercises

Routine physical therapy

Other

For control group routine physical therapy will be applied for strength training using weights and running drills for endurance training. The exercise will be given 3 times/ week for 4 weeks. For standardization control group will receive 10 minutes of warm up and cool down period comprising of stretching exercises

Primary outcomes

  1. Strength

    Time frame: From enrollment to the end of treatment at 4 weeks

    The grip strength will be measured using Hand Held Dynamometer (model). Lower limb strength will be measured through vertical jump test

  2. Muscle endurance

    Time frame: From enrollment to the end of treatment at 4 weeks

    The sit-up test will be used to assess muscular endurance

  3. Flexibility

    Time frame: From enrollment to the end of treatment at 4 weeks

    The flexibility will be assessed using sit and reach test
