“…Schoenfeld et al [11] reported increased rectus abdominus and EO muscle activity during the modified plank exercise. In addition, when the posture with hip abduction was maintained in the stance position, the activity of the anterior muscles of the trunk was greater on an unstable surface than in the stable basal plane [12]. As shown in the above study, the addition of limb movements to the trunk muscle stabilization exercises further increased abdominal activation [13], and in particular, the movement of one limb further increased the activity of the abdominal muscles associated with trunk stability [14].…”

The purpose of this study was to investigate the conditions for the application of various plank exercises to people who require trunk stabilization by comparing trunk muscle activity according to the degree of hip abduction in the plank exercise. Design: Cross-sectional study. Methods: Twenty healthy participants voluntarily participated in this study and the plank exercise was performed under 5 conditions (two-legged support plank [TSP] with hip abduction, TSP with hip abduction of 15 degrees, TSP with hip abduction of 30, one-legged support plank [OSP] with hip abduction of 15 degrees, OSP with hip abduction of 30 degrees). In order to measure the trunk muscle activity according to the 5 conditions, surface electromyography was used. The electrical activities of the rectus abdominis (RA), external oblique (EO), and internal oblique (IO) muscles were measured during the 5 plank exercises. Subjects practiced each of the 5 conditions three times in random order and the average values were obtained. Results: In the OSP condition with 15/30 degrees of hip abduction, activities of the RA, EO, and IO were significantly greater than during the TSP (p<0.05). In the OSP with 30 degrees of hip abduction condition, activities of the left EO, IO were significantly greater than other plank exercise conditions (p<0.05). Conclusions: The plank exercise with hip abduction of 30 degrees and the OSP exercise can be suggested as an effective method to enhance the activity of the trunk oblique muscles.

Background: Abdominal and lumbo-pelvic stability alterations may origin lower limb injuries, such as for example adductor pathology in soccer players. Imbalance can be caused by both intrinsic and extrinsic factors. Methods: This randomized controlled trial conducted over an 8-week period included 25 female footballers randomly allocated to an experimental group (isometric abdominal training and gluteus medius-specific training) or a control group (isometric abdominal training). The exercise protocol in common for both groups included three exercises: Plank, Lateral plank and Bird dog. Specific exercises for the gluteus medius were: Pelvic drop and Stabilization of the gluteus medius in knee valgus. Outcome measures were lumbo-pelvic stability and adductor strength.Results. Lumbo-pelvic stability after surgery was higher in the control group (MD: 4.84 vs MD: 9.58; p < .01) with differences in the analysis of repeated measures (p<.001), but not in group interaction (p =.26). Changes were found in adductor strength in the experimental group (MD: -2.48; p<.001 in the left adductor; MD: -1.48; p<.01 in right adductor) and control group (MD: -1.68; p<.001 in the left adductor; MD: -2.05; p<.001 in the right adductor) after the intervention, with differences in the analysis of repeated measures in left (p<.001) and right (p<.001) adductor strength.Conclusions. An abdominal and gluteal training protocol shows no advantage over a protocol of abdominal training alone for lumbo-pelvic stability and adductor strength and flexibility, while improvements are maintained at four weeks follow-up. Trial Registration Number: NCT03617887.

“…Significantly, in addition to the focus on trunk strengthening exercises, further training methods involving neuromuscular, sensorimotor training or combinations of these have emerged in the last years ( Saragiotto et al, 2016 ; Arampatzis et al, 2017 ; Mueller et al, 2018b ; Niederer et al, 2020 ). Core-specific sensorimotor exercises are an effective method to improve the neuromuscular activity of the trunk musculature and consequently improve trunk stability ( Arampatzis et al, 2017 ; Mueller et al, 2018a , b ). Sensorimotor training emphasizes activation of the deep trunk muscles ( Hodges and Moseley, 2003 ), improves muscle control, and enhances inter- and intramuscular coordination ( Gruber and Gollhofer, 2004 ).…”

Intervention in the form of core-specific stability exercises is evident to improve trunk stability. The purpose was to assess the effect of an additional 6 weeks sensorimotor or resistance training on maximum isokinetic trunk strength and response to sudden dynamic trunk loading (STL) in highly trained adolescent athletes. The study was conducted as a single-blind, 3-armed randomized controlled trial. Twenty-four adolescent athletes (14f/10 m, 16 ± 1 yrs.;178 ± 10 cm; 67 ± 11 kg; training sessions/week 15 ± 5; training h/week 22 ± 8) were randomized into resistance training (RT; n = 7), sensorimotor training (SMT; n = 10), and control group (CG; n = 7). Athletes were instructed to perform standardized, center-based training for 6 weeks, two times per week, with a duration of 1 h each session. SMT consisted of four different core-specific sensorimotor exercises using instable surfaces. RT consisted of four trunk strength exercises using strength training machines, as well as an isokinetic dynamometer. All participants in the CG received an unspecific heart frequency controlled, ergometer-based endurance training (50 min at max. heart frequency of 130HF). For each athlete, each training session was documented in an individual training diary (e.g., level of SMT exercise; 1RM for strength exercise, pain). At baseline (M1) and after 6 weeks of intervention (M2), participants’ maximum strength in trunk rotation (ROM:63°) and flexion/extension (ROM:55°) was tested on an isokinetic dynamometer (concentric/eccentric 30°/s). STL was assessed in eccentric (30°/s) mode with additional dynamometer-induced perturbation as a marker of core stability. Peak torque [Nm] was calculated as the main outcome. The primary outcome measurements (trunk rotation/extension peak torque: con, ecc, STL) were statistically analyzed by means of the two-factor repeated measures analysis of variance (α = 0.05). Out of 12 possible sessions, athletes participated between 8 and 9 sessions (SMT: 9 ± 3; RT: 8 ± 3; CG: 8 ± 4). Regarding main outcomes of trunk performance, experimental groups showed no significant pre–post difference for maximum trunk strength testing as well as for perturbation compensation (p > 0.05). It is concluded, that future interventions should exceed 6 weeks duration with at least 2 sessions per week to induce enhanced trunk strength or compensatory response to sudden, high-intensity trunk loading in already highly trained adolescent athletes, regardless of training regime.
