CARDIOVASCULAR ENDURANCE AMONG COMMUNITY DWELLING ELDERLY POPULATION WITH OA KNEE - CROSS SECTIONAL STUDY
Keywords:2 min walk test, aerobic capacity, bilateral, unilateral, arthritis, oxygen uptake
Background: Cardiorespiratory fitness is ability of circulatory and respiratory systems to supply oxygen to skeletal muscles, and to utilize it during physical activity. With aging of population, there is greater prevalence of osteoarthritis and decrease in aerobic capacity after age of 65 years. Hence the purpose of this study is to evaluate cardiovascular endurance among elderly with OA knee.
Methodology: 2 min walk test was performed over 30m course. Distance covered by the subject was recorded. The rest period of 10 min was given and the test was repeated. The one in which more distance is covered was taken as final result. Result: Recorded values of cardiovascular endurance in both OA knee individuals are less than normal values and it is reduced in bilateral than unilateral. Conclusion: Cardiovascular endurance is reduced in bilateral OA knee individuals than unilateral.
