Figures
Bland-Altman plot of the reached stage during the first and second 10-m Shuttle Ride Tests (SRiTs). A difference in reached stage (y axis) >0 indicates a better test score at the second SRiT, whereas a difference in reached stage <0 represents a better test score at the first SRiT. The numbers above each marker represent participant numbers, which correspond to those in Table 1.
Tables

Physiological Responses to the SRiT (n=s13)a
↵a Values are presented as mean±SD. CI=confidence interval, HRpeak=heart rate at peak exercise, bpm=beats per minute, ICC=intraclass correlation coefficient, NA=not applicable, NS=not statistically significant, O2 pulse=oxygen pulse, RERpeak=respiratory exchange ratio at peak exercise, Spo2peak=peripheral measured oxygen saturation at peak exercise, SRiT=10-m Shuttle Ride Test, V̇epeak=minute ventilation at peak exercise, V̇e/V̇co2 slope=minute ventilation-to-carbon dioxide production relationship, V̇e/V̇o2 slope=minute ventilation to oxygen uptake production relationship, V̇o2peak=oxygen uptake at peak exercise, ΔVAS=visual analog scale for the rating of perceived exertion (posttest VAS minus pretest VAS).
b 95% confidence interval of the difference between the means.
c n=12, heart rate was not determinable in 1 participant.
d n=11, invalid respiratory gas analysis measurements in 2 participants.
e n=10, invalid respiratory gas analysis measurements in 3 participants.
f n=10, invalid respiratory gas analysis measurements in 2 participants, and the ventilatory threshold was not determinable in 1 participant.
g Wilcoxon signed rank test.
h Not applicable, Wilcoxon signed rank test.
i n=9, invalid respiratory gas analysis measurements in 3 participants, and heart rate was not determinable in 1 participant.
j n=12, oxygen saturation was not determinable in 1 participant.

Clinical Characteristics of the Participants (n=13)a
↵a ADL=activities of daily living, BMD=bone mineral density, BMI=body mass index, NA=not applicable, OI=osteogenesis imperfecta.
b Modified Bleck scale according to Engelbert et al.15
c z score based on Wind et al.17
d Undeterminable due to rodding for scoliosis.
