Development of New Estimation Formula Based on Astrand-Ryhming Step Test Protocol for VOmax Evaluation of Adolescents (13-18 years)
PURPOSE To develop and validate regression models to estimate maximal oxygen uptake (VO2max) from the new estimation formula based on Astrand-Ryhming step test protocol (AR protocol) in Korean male and female youths aged 13-18 years. METHODS One hundred twenty participants performed maximal graded e...

| description | PURPOSE To develop and validate regression models to estimate maximal oxygen uptake (VO2max) from the new estimation formula based on Astrand-Ryhming step test protocol (AR protocol) in Korean male and female youths aged 13-18 years. METHODS One hundred twenty participants performed maximal graded exercise test (GXT) on a treadmill and Astrand-Ryhming step test (AR test) to measure VO2max and VO2max estimates, respectively. Participants in the validation study performed the GXT with the stationary metabolic cart and the Astrand-Ryhming step test twice for test-retest reliability. All tests were conducted at least three days apart and in a random order. RESULTS Mean calculated VO2max (40.43±11.57 mL/kg/min) from the Astrand-Ryhming step test equation was significantly low from that measured during the GXT from stationary metabolic cart (47.32±8.75 mL/kg/min, p<.01). New regression equations were developed from present data to predict VO2max for male and female youths: y=(-13.963×sex)-(0.216×W)-(0.072×HR)+91.296 (r=.772, SEE=5.64 mL/kg/min).The VO2max (47.22±6.76 mL/kg/min) of modified Astrand-Ryhming step test equation showed no significant difference from the VO2max measured through GXT. CONCLUSIONS It is concluded that this equation developed in this study provides valid estimates of VO2max of Korean male and female youths aged 13-18 years.A further study needs to develop a step test estimation equation targeting adults and elderly people in which validity and reliability are secured. |
