“…LT muscle activity in the prone position was greater than muscle activity in the standing position. The findings of this study are in agreement with a previous study that reported increased LT activation during arm lifts in prone and backward rocking quadruped positions compared with arm lifts in the standing position (Ha et al, 2012). The LT muscle tilts the scapular backward and assists complete shoulder flexion in the terminal phase.…”

“…However, the result of a previous study might support that there was no significant difference in the muscle activity of SA between the arm lift against the wall in the standing position and the prone position. Moreover, the muscle activity in the wall standing position was greater than that in the prone position (Ha et al, 2012).…”

“…A recent study reported that the backward rocking diagonal arm lift induced greater activity in the LT than the backward rocking arm lift and wall facing arm lift, and the backward rocking arm lift induced greater activity in the SA than other exercises did (Ha et al, 2012). However, no previous studies reported the effect of ADIM on trunk muscle activity during arm lifts in prone and standing positions.…”

1)The aim of this study is to compare the effect of abdominal drawing-in maneuver (ADIM) on lower trapezius (LT), serratus anterior (SA), and erector spinae (ES) muscle activity during arm lifts in prone and standing positions. Twenty healthy subjects were recruited, and NoraxonTeleMyo 2400T was used to collect electromyographic signals from the LT, SA, and ES muscles. A two-way repeated analysis of variance (ANOVA) used a significance level of .05. If a significant interaction was found, pairwise comparisons were performed with a Bonferroni adjustment (.05/4=.013). The results of the study were as follows: 1) In LT, no significant ADIM by position interaction was found (F1, 19=.356, p=.558). There was a significant main effect for ADIM. LT muscle activity with ADIM was significantly greater compared with muscle activity without ADIM (F1, 19=82.863, p<.001). There was also a significant main effect for position. LT muscle activity in the prone position was greater compared with muscle activity in the standing position (F1, 19=116.401, p<.001). 2) In SA, significant ADIM by position interaction was found (F1, 19=8.687, p=.008). There were significant differences in all pairwise comparisons. The greatest SA muscle activity was observed in the standing position with ADIM. 3) In ES, significant ADIM by position interaction was found (F1, 19=122.473, p<.001). The lowest ES muscle activity was elicited in the standing position with ADIM. Based on these results, ADIM is advocated in the prone position to increase LT muscle activity. In addition, it is concluded that arm lifts in the standing position with ADIM offer the most favorable combination for reducing ES muscle activity and increasing SA muscle activity.[Ki-song Kim, One-bin Lim, Chung-hwi Yi, Heon-seock Cynn.

“…Many previous studies have examined the effectiveness of various exercises to increase the flexibility of PM and the activity of LT and SA, including stretching techniques of PM (Borstad & Ludewig, 2005, 2006Muraki et al, 2009;Roddey, Olson, & Grant, 2002;Wang, McClure, Pratt, Nobilini, &, 1999;Williams, Laudner, & McLoda, 2013) and strengthening exercises focusing on the LT and SA muscles (Arlotta, LoVasco, & McLean, 2011;Ekstrom, Donatelli, & Soderberg, 2003;Ha et al, 2012;Hardwick, Beebe, McDonnell, & Lang, 2006;Pontillo, Orishimo, Kremenic, McHugh, Mullaney, & Tyler, 2007). Of these various exercises, the selfstretching technique (Borstad & Ludewig, 2006) and gross stretching technique (Williams et al, 2013) resulted in significant increases in the length of PM compared to the other stretching techniques.…”

“…These two injuries are connected with dysfunctional glenohumeral and scapulothoracic kinematics and weak, or insufficient, stabilising musculature [5]. The main stabilising muscles for the shoulder are the lower and middle trapezius and serratus anterior [6,7]. Dysfunctional kinematics of the shoulder stabilising muscles while climbing may be associated with changed timing properties of the aforementioned muscles and predominant activation of the upper trapezius.…”

Abstract:Objective:The aim of the study was to determine electromyographic activity of the scapula stabilizing muscles in naturally chosen and corrected shoulder positions in typical static climbing postures. Methods:Six male participants undertook surface electromyography measurement in four climbing postures for two different shoulder positions. The activity of the lower, middle and upper trapezius, serratus anterior, pectoralis major, and sternocleidomastoid was recorded. Electromyographic activity was expressed as the percentage of maximal voluntary contraction (MVC) for each muscle. Results:Climbing postures induced higher activation of middle and lower trapezius in corrected shoulder positions (35.3 ± 11.8 and 61.7 ± 15.4% MVC respectively) than in naturally chosen shoulder positions (18.4 ± 8.9 and 30.1 ± 13.8% MVC respectively). The highest activity of the middle and lower trapezius was found in postures with the arm in external rotation and 90° abduction and in an overhanging posture. Low activation was stated for the other muscles in both shoulder conditions. Conclusion:Results showed that climbers naturally elevate the shoulder during typical static postures. Corrected shoulder positions induce higher activation of the scapula stabilizing muscles than naturally chosen shoulder positions.
