A Comparison of Warm-Up Effects on Maximal Aerobic Exercise Performance in Children

Abstract

The aim of this study was to compare the warm-up effects of treadmill walking (TW) with a dynamic (DY) bodyweight warm-up on maximal aerobic exercise performance in children. Sixteen children (10.9 ± 1.5 vrs) were tested for peak oxygen uptake (VO2 peak) on 2 nonconsecutive days following different 6 min warm-up protocols. TW consisted of walking on a motor-driven treadmill at 2.2 mph and 0% grade whereas the DY warm-up consisted of 9 body weight movements including dynamic stretches, lunges, and jumps. Maximal heart rate was significantly higher following DY than TW (193.9 ± 6.2 vs. 191.6 ± 6.1 bpm, respectively; p = 0.008). VO2 peak (54.8 ± 9.6 vs. 51.8 ± 8.7 mL/kg/min; p = 0.09), maximal minute ventilation (68.9 ± 14.8 vs. 64.9 ± 9.4 L/min; p = 0.27), maximal respiratory exchange ratio (1.12 ± 0.1 vs. 1.11 ± 0.1; p = 0.85) and total exercise time (614.0 ± 77.1 vs. 605 ± 95.0 s; p = 0.55) did not differ significantly between DY and TM warm-ups, respectively. These findings indicate that the design of the warm-up protocol can influence the heart rate response to maximal aerobic exercise and has a tendency to influence VO2 peak. A DY warm-up could be a viable alternative to a TW warm-up prior to maximal exercise testing in children.

“…Compared to other stretching methods, DSG performance may increase core body temperature more (Günay et al,2023). There are also studies that suggest that DG stretching exercises increase flexibility, vertical jump height and sprint performance (Faigenbaum et al, 2022;Fletcher and Anness, 2007 ;Little and Williams, 2006;McMillian et al, 2006;Yamaguchi and Ishii, 2005). In addition, it has also been observed that DG exercises increase the performance of a 20 m sprint (Fletcher and Jones, 2004).…”

“…The stretching was performed at a moderate level and 3-step walking intervals were performed during the relaxation. The movements were designed with 10 s rest in between and the total duration was limited to 5 min (Faigenbaum et al, 2022;Günay et al, 2023;Holt and Lambourne, 2008;Manoel et al, 2008;Unick et al, 2005;Zmijewski et al, 2020).…”

“…En este sentido, la realización del WU parece tener efectos inmediatos y a corto plazo en múltiples sistemas corporales que influirán de forma positiva, negativa o neutra en la práctica posterior. Entre los efectos fisiológicos parece que el WU activo produce incremento de la frecuencia cardíaca (FC) (Ückert & Joch, 2007), elevación de la frecuencia respiratoria (Faigenbaum et al, 2022), un aumento del uso de glucógeno muscular (Starkie et al, 1999) y regulación de la liberación de determinadas hormonas (Casto & Edwards, 2016), entre otros.…”
