Investigation of electromyographic activity during Salat and stretching exercise
2012 2nd IEEE-EMBS Conference on Biomedical Engineering and Sciences, IECBES 2012, 2012
Salat is a formal prayer practice by all Muslims. When performing salat, it involves with several movements namely standing, takbeer, bowing, prostration and sitting. The study was to quantify and compares the muscle activity (surface electromyographic signal) during Salat and stretching exercise. Three main movements in Salat (takbeer, bowing and prostration) and similar stretching exercises to the Salat movements were investigated. Thirty one male and female volunteers were participated in this study. The activity of the four investigated muscles: biceps brachii, triceps brachii, pectoralis major and upper trapezius were recorded during salat and stretching movements. The recorded signals were then analyzed using root mean square analysis. The results indicate similar muscle contractions activities during salat and stretching exercise. Even though, the root mean square values during stretching exercise is higher, a t-test shows there is statistically no significant difference between these two movements © 2012 IEEE. http://ieeexplore.ieee.org/xpls/abs\_all.jsp?arnumber=6498012
Electromyographic Activity of the Upper Limb Muscleduring Specific Salat’s Position and Exercise
International Journal of Applied Physics and Mathematics, 2013
This study investigated the muscle activity of the neck extensors (NE), sternocleidomastoideus (SCM) and biceps brachii (BB) muscles in healthy subjects during salat and specified exercises using surface electromyography (EMG). A group of undergraduates aged between 19 to 25 years voluntarily participated in this study. For the assessment of the NE and SCM, the subjects were asked to perform salat (salam's position) and exercise [neck rotation exercise (NRE)]. Subjects were asked to perform takbir's position and biceps dumbbell curl (BDC) to access BB. The EMG and the motion signals of the muscles were recorded. The findings indicate that there were contractions of the muscles during the salat and exercise with difference EMG level. For NE and SCM, Wilcoxon's Rank Sum Test showed a statistically no significant difference between salat and exercise for NE (p = 0.482) and SCM (p=0.161). For the BB, Wilcoxon's Rank Sum Test showed a statistically significant difference between salat and exercise (p<0.05) with differences 18.48% MVC. However, BB showed the EMG level with mild contraction. Therefore, salat may be useful in warm up exercise or in rehabilitation programs. This pilot study can be as initial research about other biomechanical response of human muscle with other position in salat.
Surface electromyography analysis of three squat exercises 1 2
2018
26 The aim of this study was to perform an electromyography comparison of three commonly 27 used lower limb injury prevention exercises: a single-leg squat on a bench (SLSB), a double-leg 28 squat (DLS) and a double-leg squat on a BOSU® balance trainer (DLSB). After determining the 29 maximum isometric voluntary contraction of the hamstring and quadriceps, eight female athletes 30 performed 3 repetitions of each exercise, while electromyography activity of the biceps femoris 31 (BF), semitendinosus (ST), vastus lateralis (VL) and vastus medialis (VM) was monitored. 32 Comparisons between exercises revealed higher activation in BF (descending phase: p = 0.016, d = 33 1.36; ascending phase: p = 0.046, d = 1.11), ST (descending phase: p = 0.04, d = 1.87; ascending 34 phase: p = 0.04, d = 1.87), VL (ascending phase: p = 0.04, d = 1.17) and VM (descending phase: p 35 = 0.05, d = 1.11; ascending phase: p = 0.021, d = 1.133) muscles for the SLSB compared to the 36 DLSQ. Furthermore, higher...

Assessment of upper body muscle activity during salat and stretching exercise: A pilot study
IEEE-EMBS International Conference on Biomedical and Health Informatics, BHI 2012. In Conj. with the 8th Int. Symp.on Medical Devices and Biosensors and the 7th Int. Symp. on Biomedical and Health Engineering, 2012
Salat is the practice of formal prayer for Muslims. It involves with both spiritual and physical acts. This paper presents electromyography (EMG) output during the "takbeeratul-ihram (TI)", one of the postures in Salat and stretching exercise. Comparisons on EMG outputs between TI and stretching exercise are discussed. Ten healthy participants (five males and five females) were recruited for the investigation. The EMG signals were recorded from back scapula, upper trapezius, biceps brachii and pectoralis major muscles. The results showed that higher EMG signals in pectoralis major and biceps during performing the stretching posture. However, for TI posture, the EMG activities are higher in back scapula and upper trapezius muscles. © 2012 IEEE. ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6211603
This paper investigates the activity of the gastrocnemius (Gas) muscle in healthy subjects during salat (ruku' position) and specific exercise [Unilateral Plantar Flexion Exercise (UPFE)] using electromyography (EMG). Both lateral and medial Gas muscles were assessed. A group of undergraduates aged between 19 to 25 years voluntarily participated in this study. The myoelectric activity of the muscles were recorded and analyzed. The finding indicated that there were contractions of the muscles during the salat and exercise with almost same EMG's level. From the result, Wilcoxon's Rank Sum test showed no significant difference between ruku' and UPFE for both medial (p=0.082) and lateral (p=0.226) of GAS muscles. Therefore, salat may be useful in strengthening exercise and also in rehabilitation programs for lower limb activities.
Electromyography Analysis of Lower Extremity Muscles during Squat and Stoop Movement
IOP Conference Series: Materials Science and Engineering, 2020
There are different styles of lifting objects of the ground, and each style gives out different percentage of contribution of each muscle. The purpose of this study is to investigate the muscle activity between stooping and squatting to avoid low back pain and how the muscle activities differ from a correct technique of squatting, and an incorrect one. The Rectus Abdominis, Erector Spinae, Quadriceps and Hamstrings muscle were chosen to be monitored for differences in this study. Selected subjects were two healthy males, with the same height and age, one subject has no experience in doing squats – define as amateur, and the other subject know the basic method of squat-ting – define as non-amateur. In order to capture and analyze the activity of the muscles, Myon EMG and ProEMG software were used. Participants performed, stooping and squatting movement for 12 repetitions with 5 minutes’ rest in between. The muscle activation strength was obtained by calculating the Root Mean Square o...
Electromyography of the thigh muscles during lifting tasks in kneeling and squatting postures
Ergonomics, 2011
Underground coal miners who work in low-seam mines frequently handle materials in kneeling or squatting postures. To assess quadriceps and hamstring muscle demands in these postures, nine participants performed lateral load transfers in kneeling and squatting postures, during which electromyographic (EMG) data were collected. EMG activity was obtained at five points throughout the transfer for three quadriceps muscles and two hamstring muscles from each thigh. ANOVA results indicated that EMG data for nine of 10 thigh muscles were affected by an interaction between posture and angular position of the load lifted (p 5 0.001). Muscles of the right thigh were most active during the lifting portion of the task (lifting a block from the participant's right) and activity decreased as the block was transferred to the left. Left thigh muscles showed the opposite pattern. EMG activity for the majority of thigh muscles was affected by the size of the base of support provided by different postures, with lower EMG activity observed with a larger base of support and increased activity in postures where base of support was reduced (p 5 0.05). Thigh EMG activity was lowest in postures with fully flexed knees, which may explain worker preference for this posture. However, such postures are also associated with increased risk of meniscal damage.
Muscle Activity Estimation through Surface EMG Analysis during Salat
Salat may be useful in warm up or in rehabilitation programs. This study explores the muscle potential and force during Salat’s movement and position that can be one of the daily exercise and training for our muscle in course of biomechanical response of human body. From this study, it is possible to recognize the muscles that are involved and contract during Salat. In case of signal acquisition, subjects selection and data collection steps are accomplished by hardware setup. We have analyzed the signals through Average Rectified Value and Root Mean Square method and the locations of muscle activity were determined to acquire the expected data. Significantly, the signal was taken along three different muscles: Biceps Brachii (BB), Erector Spinae (ES), and Gastrocnemius Medialis (GM) during Salat and Treadmill exercise. A Number of healthy subjects of male and female were chosen for assisting the study. EMG (Electromyography) and Integrated EMG data were recorded for several test conditions to determine active muscle points. The findings indicate that during Salat, BB and ES produce better EMG level for both male and female subjects against Treadmill exercise. On the other side, GM has higher EMG during Treadmill than Salat. By this work, we have explored that Salat is spiritual and physical act in where, nearly all muscles of human body become more active than any kind of physical exercise without muscle fatigue.
