摘要

Purpose: The study was to investigate the validity of the modified squat test to assess cardiopulmonary fitness in healthy young adults. Method: Eighteen subjects (10 males, 8 females, aged 22.2±2.7 years)were recruited. Each subject performed a modified squat test and a maximal exercise test to determine maximal oxygen consumption (V4O(subscript 2max)). When performing the modified squat test, the subject started at standing position with his/her elbows 90° flexed at the sides of the waist. Then, with a custom-made lightweight equipment, the subject was guided to squat down to 45° knee flexion, and at the same time, both arms pushed out. The subject repeated the sequences at a rate of 120 cycles/min for 3 minutes. Recovery heart rates(HR) were measured following the modified squat test. The fitness indices of the modified squat test, including (1)The sum of recovery HR during 0-30, 60-90 and 120-150 seconds (2)The sum of recovery HR divided by weight (3)0-30 recovery heart rate divided by weight (4)0-30 recovery heart rate divided by BMI, were tested to correlate with V4O(subscript 2max). Results: Pearson’s correlation analysis showed significant correlations (p＜0.01) between the V4O(subscript 2max) (l/min)and the sum of recovery HR divided by weight (r=-0.63), 0-30 recovery heart rate divided by weight (r=-0.88) and 0-30 recovery heart rate divided by BMI (r=-0.82). No significant correlation between the V4O(subscript 2max) (l/min)and the sum of recovery HR was found. Within the fitness indices we tested, the 0-30 recovery heart rate divided by weight revealed the highest correlation. Conclusion: The modified squat test is a valid test for evaluating fitness level in healthy young individuals. The index of the modified squat test is 0-30 recovery heart rate divided by weight.
