Non-exercise Prediction Of Anaerobic Power

Abstract

Previous studies have documented that reasonable estimates of maximal oxygen uptake can be obtained through the combination of selected anthropometric data and a paper and pencil test. PURPOSE: This study examined the possibility of predicting anaerobic power as measured by the Wingate Anaerobic Cycle Test using anthropometric data and a questionnaire. METHODS: Ninety-seven (54 males and 43 females) subjects volunteered to participant in this study. Peak power (PP) and mean power (MP) were determined using a standard Wingate protocol at a resistance of 0.075 and 0.10 kg*kgbw-1 for females and males, respectively. A series of eight questions were generated corresponding to variables associated with anaerobic power, using a Likert-type scale to quantify the response. Additionally, previously published scales from papers investigating non-exercise aerobic power estimates were also included in the analysis (Jackson et al, 1995 and George et al, 1997). Descriptive statistics were generated and multiple regression were performed on SAS v9.0 with an alpha level of p<0.05. RESULTS: Mean (± SD) age, ht, wt, BMI, resting heart rate (RHR), PP, and MP, for males and females were: 21.9±2.5yrs, 175.0±7.8cm, 79.2±12.4kg, 25.8±3.3, 67.3±12.1BPM, 1055.7±192.2W and 800.7±125.7W; and 22.4±3.3yrs, 163.7±7.6cm, 61.0±11.2kg, 22.7±3.8, 69.7±10.3BPM, 607.9±121.6W and 481.7±71.0W; respectively. The mean estimated jump height (EJHt) Likert-scale values were 5.7 ± 1.5 and 4.7 ± 1.3 (on a 1-9 scale) for the males and females respectively. The mean activity code (AC) (Jackson et al. 1995) was 4.9 ± 1.6 and 5.1 ± 1.5 for males and females respectively. Multiple regression revealed the most parsimonious models to predict PP and MP were: PP = 195.97 + 257.05(gender; female=0, male=1) +8.48(wtkg) + 2.81(EJHt)2 -2.48(RHR), R2 = 0.80, SEE = 122.9 W; MP = 214.83 + 180.93(gender) +0.06(wtkg) 2 - 0.16(BMI) 2 + 66.31(AC) -5.97(AC) 2 + 14.8(EJHt) -1.54(RHR), R2 = 0.91, SEE = 60.0 W. CONCLUSION: It was concluded that reasonable estimates for Peak and Mean power could be estimated from a combination of anthropometric data and a questionnaire without performing the Wingate anaerobic cycle test.
