AIM: The purpose of the study was first to evaluate the anaerobic power in elderly women aged from 50 to 70 years with three different methodologies of anaerobic tests on the same cycle-ergometer, and secondly to measure anaerobic power and aerobic power and to compare the relationship between aerobic (PmaxAer) and anaerobic power (PmaxAn) (Power Index [PImax]) as reference values for women in this age group.
METHODS: Three different techniques were used to determine anaerobic power (classical Wingate test, isokinetic test and single all out test) in 39 untrained subjects. PmaxAer was assessed by an incremental cycle test. All measurements were performed on the same ergometer.
RESULTS: The maximum power during the aerobic test (PmaxAer rel.) was 1.93 W/kg (±0.4). The anaerobic tests show a similar maximal performance during the isokinetic test (IsoPpeak rel.: 5.56±1.5) and the Wingate Test (WinPpeak rel.: 5.88±1.0). Subjects achieved the highest maximum values during the force-velocity test (NonIsoPpeak rel.: 11.34±2.5). In addition, we found significant correlation between the three anaerobic tests (r=0.743-0.789; P<0.001). The ratio between aerobic and anaerobic power (PImax) was 34±3.6%.
CONCLUSION: The study sets up reference values for this barely investigated population. Our results suggest that all three used protocols to assess anaerobic power are useful methods. PImax does not change whereas maximal aerobic and anaerobic values decrease with age.
