The present study assessed maximal oxygen uptake during the Multistage Fitness Test (MSFT) and treadmill procedure. Maximal oxygen uptake was calculated by using predictive equations (Leger et al., 1988; Ramsbottom et al., 1988; Barnett et al., 1993) and was directly measured by using a portable gas analyser. This was achieved to validate the use of predictive equations to estimate maximal oxygen uptake from the MSFT within adult females and pre-pubescent girls. The MSFT and treadmill tests were performed by 10 adult females (age 20.9 ± 6.37 years; height 163.7 cm ± 49.8; mass 56.6 kg ± 17.7) and 5 pre-pubescent children (age 10.8 ± 0.8; height 147.9 cm ± 5.2; mass 37.6 kg ± 3.30; maturity offset - 0.85 years ± 0.66) all of which were regularly engaged in sport. During these tests maximal oxygen uptake, heart rate and respiratory exchange ratio were measured. Pearson’s correlation and Bland-Altman tests were used to analyse the data. Results show predicted and recorded MSFT scores to produce significant positive correlations within both age categories (Adult P=0.000; R2=0.50; Child- Leger et al., 1988 P= 0.001 and R2=0.55; Child- Barnett et al., 1993 P= 0.004 and R2=0.75). The two tests also produced a strong correlation for both age groups (Adult P= 0.22; R2=0.50; child P=0.62; R2=0.04). The accuracy of the predictive equation used, varied considerably when calculating maximal oxygen uptake from the MSFT. The bias varied from -11.4ml.kg.min-1 (Ramsbottom et al., 1988) to 9.27ml.kg.min-1 (Leger et al., (1988). Results suggest the MSFT is a valid predictor of maximal oxygen uptake within adult females and pre-pubescent girls. Future research must carefully consider which predictive equation is most relevant for the participants they are testing.
