Effect of abdominal drawing-in maneuver during hip extension on the muscle onset time of gluteus maximus, hamstring, and lumbar erector spinae in subjects with hyperlordotic lumbar angle.

Kim T, Woo Y, Kim Y - J Physiol Anthropol (2014)

Bottom Line: During ADIM application, the muscle contraction onset time of the gluteus maximus was significantly increased in the LHLA group compared with the LNLA group.ADIM application during prone hip extension was more effective for gluteus maximus onset time in the LHLA group.Therefore, ADIM during prone hip extension may be useful for gluteus maximus training in individuals with lumbar hyperlordosis.

ABSTRACT

Background: The abdominal drawing-in maneuver (ADIM) is used to prevent abnormal movements of the lumbar spine and pelvis during therapeutic exercises. This study compared the effects of ADIM on the muscle onset time of the hamstring, gluteus maximus, and erector spinae muscles during prone hip extension exercise in subjects with or without hyperlordotic lumbar angle. Forty healthy adults (18 male, 22 female) were recruited for this study.

Methods: The lumbar lordotic angles and pelvic tilt angles of the subjects were measured using the Avaliação postural analysis software. The subjects were divided into two groups: the lumbar hyperlordotic angle (LHLA) and lumbar normal lordotic angle (LNLA) groups. The muscle contraction onset time of the hamstring, gluteus maximus, and erector spinae were assessed using surface electromyography.

Results: During ADIM application, the muscle contraction onset time of the gluteus maximus was significantly increased in the LHLA group compared with the LNLA group.

Conclusions: ADIM application during prone hip extension was more effective for gluteus maximus onset time in the LHLA group. Therefore, ADIM during prone hip extension may be useful for gluteus maximus training in individuals with lumbar hyperlordosis.

Mentions: There was no significant main effect for condition for the muscle onset time of the HAM (F1,38 = 0.000, P = 1.000), GM (F1,38 = 1.703, P = 0.197), or LES (F1,38 = 0.145, P = 0.705). An intra-group comparison of the HAM muscle onset time in the LHLA group showed that the muscle onset time was 2.24 ± 0.24 ms without ADIM application and 2.18 ± 0.19 ms with ADIM application, but this change was not significant (P >0.05; Figure 3). For the GM, the muscle onset time was 2.72 ± 0.37 ms before ADIM application and 1.92 ± 0.27 ms after ADIM application, and this difference was significant (P <0.01; Figure 3). For the LES, the muscle onset time was 2.11 ± 0.21 ms before ADIM application and 2.20 ± 0.40 ms after ADIM application, but this difference was not significant (P >0.05; Figure 3). There was no significant main effect of lordotic angle on HAM (F1,38 = 0.035, P = 0.853), GM (F1,38 = 0.348, P = 0.558), or LES (F1,38 = 0.211, P = 0.648) muscle onset time.Figure 3
