Shuttle walking test in obese women: test‐retest reliability and concurrent validity with peak oxygen uptake

Abstract

The ISWT had excellent reliability as well as good concurrent validity and agreement. The ISWT may be a potential tool for monitoring clinical status and intervention efficacy (e.g. programmes for weight loss and rehabilitative strategies) in this population.

Reliability of Cardiorespiratory and Metabolic Responses During Incremental Shuttle Walk Test in Adult Subjects With Asthma

“…30 We found a heart rate mean error value of Ϫ4.4 beats/min, which is close to zero, and limits of agreement ranging from Ϫ41.9 to 33.1 beats/min. These values were similar to the results obtained by Jürgensen and colleagues 28 and by Booth and Adams. 32 The expected heart rate was in the range of 110 -190 beats/min, which is similar to that found by Jürgensen and colleagues 28 (ie, 120 -180 beats/min), but different from the one obtained by Booth and Adams 32 (ie, 80 -140 beats/min).…”

“…Seven previous studies tested the test-retest reliability for the ISWD, with ICCs ranging from 0.80 to 0.99. 13,[23][24][25][26][27][28] These results are consistent with study findings in other chronically ill populations.…”

“…Pepera and colleagues, 26 when studying subjects with clinically stable cardiovascular disease, found a mean error of Ϫ7 m with limits of agreement (Bland-Altman) of Ϫ203 to 189 m. Hence, the magnitude of these values (386 m) was higher than that found in our study, which was 241.4 m. Jürgensen and colleagues 28 conducted a study with obese women, finding a mean error of Ϫ5.9 with limits of agreement of Ϫ82.0 to 70.2 m, and the magnitude of these values was 148.2 m, lower than the value obtained in our study (241.4 m).…”

“…22 The expected ICC was consistent with the mean ICC for the ISWD as verified in 7 previous studies that tested its reliability (range 0.80 -0.99). 13,[23][24][25][26][27][28] Variance analysis comparing the ISWD and the cardiorespiratory and metabolic responses between the second and third ISWT was performed with a paired t test or its corresponding nonparametric test, the Wilcoxon test.…”

“…Die Reproduzierbarkeit der ISWT-Gehstrecke bei adipösen Frauen (Grad III) war mit mittlerer Differenz von 9,2 Metern gegeben [356]. In einem Vergleich von 6-MWT auf dem Laufband und einem symptomlimitierten Ausbelastungstest auf dem Laufband bei adipösen (Grad I-III) und normalgewichtigen Frau-en, zeigten in beiden Testkonditionen die adipösen Frauen signifikant höhere peak V O 2 , wobei nach Korrektur auf das Gewicht normalgewichtige Frauen höhere peak V O 2 aufwiesen [357].…”
