“…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]. Although there are several studies that show that plank exercises are effective, there are few studies that have investigated the activation of trunk muscles during plank exercises according to postural changes [9], and studies with limb movements during modified plank exercise are also lacking.…”

“…The maximum voluntary isometric contraction (MVIC) was measured after attaching electrodes to both the RA and the external and internal oblique (IO) muscles of the subjects [9]. Prior to the experiment, the researchers selected the hip joint abduction site of the lower limb.…”

“…Two-legged support plank with 0° of hip abduction In the prone position, the elbows and forearms of the upper limbs were placed on the floor and were at right angles with the shoulders. The legs were fully extended without any hip abduction and with only the tip of the feet touching the floor ( Figure 1A) [6,9].…”

“…Muscle electromyography (EMG) signals measured in this study were processed by full wave rectification using the Myoresearch XP Master edition software (2013; Noraxon Inc., Scottsdale, AZ, USA) and the root mean square. The maximum voluntary contraction (MVC) value was calculated by dividing the MVIC value by the percent MVC value [9]. Each plank posture was maintained for 5 seconds but data was analyzed during a stable period of 3 seconds with the first and last second extracted, and after the average values were obtained from repeating the measurement three times in all conditions, data was normalized to MVIC values [6,20].…”

“…Plank exercises are popular for strengthening the core muscles, including internal and EO muscles [7], and is a passive and active stabilizer of the lumbar pelvis region that maintains proper balance and control of the trunk and hip joint during both static and dynamic movement of the body [8]. Sit-ups, crunches, and plank movements spinal stabilization exercises that are effective for strengthenening the core muscles without time and space constraints [9]. When comparing sit-up exercises and plank exercises, which have been widely used as stabilizing exercises for the trunk, sit-up exercises increase the compression force on the vertebrae, making it easy to cause degenerative spinal injuries [10].…”

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.

Peak torque substantially varies between patients with non-specific low back pain; belong to directional preference classification, and healthy individuals—clinical biokinesiologic perspectives

To compare flexion and extension peak torque of patients with nonspecific-chronic low back pain who were classified as directional preference subgroups, and their matched healthy controls. [Participants and Methods] Fifty male volunteers (25 with non-specific chronic low back pain and 25 healthy-matched controls) consented to participate. The investigator collected all demographic data, hips, knees and spinal mobility in addition to the peak torque using the Biodex isokinetic dynamometer. The measurement protocol consisted of 2 sets of 10 consecutive flexion-extension efforts performed at 120°/sec and 60°/sec angular velocity. A two minutes rest period was given between sets. The preset 50° range of motion included 20°(+20°) of trunk extension and 30°(−30°) of trunk flexion. [Results] A 2 × 2 mixed-design ANOVA showed a significant group X isokinetic velocity interaction. The main effect of isokinetic velocity was also significant. In reference to the peak torque of the flexors of the trunk, the main effect of group was significant. [Conclusion] The extension peak torque significantly depends on the velocity of the isokinetic dynamometer; however the flexion peak torque significantly depends on the participants' group attribution.

Bu çalışmada geleneksel ve fonksiyonel egzersiz kayışı (FEK) ile yapılan şınav uygulamalarında, dirseklerin ekstansiyon ve fleksiyon pozisyonunda algılanan zorluk derecesinin mekanik salınımlarla karşılaştırılarak incelenmesi amaçlanmıştır. Araştırmaya 18-25 yaş arasında 38 kadın sporcu (yaş: 20,89±2,07 yıl; boy: 166,34±0,04 cm; vücut ağırlığı: 57,52±6,29 kg), 33 kadın sedanter (yaş: 19,75±2,04 yıl; boy: 163,66±0,05 cm; vücut ağırlığı: 54,97±6,12 kg) olmak üzere toplam 71 gönüllü katılmıştır. Her iki şınav uygulamasında da dirsekler ekstansiyon ve fleksiyon pozisyonunda 30 sn. bekletilmiş, uygulama sonrası pozisyonla ilgili modifiye algılanan zorluk skalası ile değerlendirme yapılmıştır. Mekanik salınımın tespiti için el bileği, omuz kuşağı ve lumbar bölge olmak üzere toplam beş adet ivme ölçer kullanılmıştır. Her iki şınav türü algılanan zorluk düzeyleri ve mekanik salınım açısından karşılaştırılmıştır. Fonksiyonel egzersiz kayışında dirsekler fleksiyon pozisyonunda en yüksek zorluk derecesi hissedilirken en fazla salınım ortaya çıkmıştır. Geleneksel şınav uygulamasında ise, dirsekler ekstansiyon pozisyonunda en az zorluk hissedilirken en az salınım gerçekleşmiştir. Algılanan zorluk dereceleri ile mekanik salınım ilişkileri incelenmesi sonucunda, algılanan zorluk derecesi arttıkça mekanik salınımın arttığı tespit edilmiştir. Özellikle spora yeni başlayanlarda kolaydan zora ilerlemedeki sıralama geleneksel şınav ekstansiyon, geleneksel şınav fleksiyon, FEK şınav ekstansiyon ve FEK şınav fleksiyon uygulaması biçiminde önerilebilir.
