The Relationship between Cardiorespiratory Fitness and Lower Cross Syndrome among Sedentary Individuals- A Correlational Study

Abstract Introduction: The American Heart Association (AHA) defined CARDIORESPIRATORY FITNESS as the maximum rate at which oxygen can be utilized by the body during maximal exertion. CRF is categorized as flexibility, body composition, aerobic capacity, and muscular fitness. The Queen’s College Step Test is one of many variations of step test procedures usead as submaximal exercise testing for CRF. sedentary lifestyle involves little or no Physical activity. One of the major factors for obesity is sedentary life style. Individuals with a high percentage of body fat tend to have higher fat distribution over the abdominal region and decreased abdominal muscle strength. Lower Crossed Syndrome (LCS) is a characterised by different patterns of muscular weakness (abdominals and gluteus maximus) and tightness (iliopsoas and spinal extensors). A test presumed to characterize abdominal strength is the double leg- lowering (DLL) for lower cross syndrome. Methodology: 196 partipants divided into 2 groups as per normal and obese according to Asian BMI classification. With job of 6–8 h./d in a sitting posture with aged 19-30 and No history of lumbar disc herniation or trauma were included. Who have active lifestyle and doing regular exercise, Pregnant had Previous back surgery, spinal tumors or infections, or neurological and/or musculoskeletal disorders were excluded. Double leg lowering test for lower cross syndrome and queen’s college step test for cardio-respiratory fitness were taken with consent. Result: Spearmen correlation co-efficient test were used within groups which shows significant correlation of lower cross syndrome and cardio-respiratory fitness (p < 0.05). Conclusion: obese individuals with sedentary lifestyle have correlation of cardiorespiratory fitness with lower cross syndrome due to weak abdominals.
