“…It also suggests that greater activation of the external oblique and lumbar spine occurred when performing a lateral contraction of the trunk, which in our case counteracted the effect of the load. Counteracting the effect of loading with the activation of muscles that are at a greater distance was also observed in the studies of Graber et al [ 10 ] and Stastny et al [ 11 ], which agrees with the Lauder et al [ 48 ] study comparing unilateral and bilateral dumbbell lifting. They found an asymmetry in activation, which was more significant on the opposite side of the load in the case of unilateral lifting in the lifting phase.…”

“…These exercises can be more functional for daily activities and more sport-specific than bilateral exercises [ 9 ]. Unilateral weight-bearing exercises are commonly prescribed for rehabilitation, and their performance generates the activation of different trunk and lower extremity muscles necessary for the performance of many daily activities [ 10 ]. They often involve multiple joints and can be used to improve overall strength, stability, and balance.…”

Background: The effect of load distribution applied to the trunk musculature with lunge exercises has yet to be determined. The aim of this study was to evaluate the effect of load placement using dumbbells on the activation of the latissimus dorsi, erector spinae, external oblique, and rectus abdominis muscles during the lunge. Methods: Forty-two amateur athletes (21 men and 21 women) were recruited. Three lunge exercises were performed with different loading arrangements (ipsilateral, contralateral, and bilateral). The principal variable recorded for muscle activity was mean “root mean square” expressed as the percentage of the maximal voluntary isometric contraction. Results: There are statistically significant differences in the erector spinae (p < 0.001; p < 0.003) and external oblique muscles (p < 0.009; p < 0.001) compared with the contralateral side. The muscle on the opposite side of the load achieved higher activation for these muscles. The erector spinae and latissimus dorsi muscle did not reach a statistically significant difference with the contralateral side in any exercise (p > 0.05). The higher activation of the latissimus dorsi occurred on the same side on which the load was placed. Conclusions: There was higher activation of the erector spinae, external oblique, and rectus abdominis muscles contralateral to the side of load placement during lunge exercise by amateur athletes.

“…With regard to postural stability, the results demonstrated that the knee OA group had greater CoM displacement and peak instantaneous velocity in the anterior-posterior direction, which could be an indication that individuals with knee OA would have a greater risk to fall backward. Some researchers have reported that individuals with knee OA showed impaired balance in other daily activities such as standing ( Truszczyńska-Baszak et al, 2020 ), walking ( Graber et al, 2021 ), and stair descending ( Koyama et al, 2015 ). Poor balance is related to muscle weakness in individuals with knee OA ( Bennell et al, 2011 ).…”

Objective: Stand-to-sit task is an important daily function, but there is a lack of research evidence on whether knee osteoarthritis (knee OA) affects the postural balance during the task. This study aimed to compare individuals with knee OA and asymptomatic controls in postural balance and identify kinematic and lower extremity muscle activity characteristics in individuals with knee OA during the stand-to-sit task.Methods: In total, 30 individuals with knee OA and 30 age-matched asymptomatic controls performed the 30-s Chair Stand Test (30sCST) at self-selected speeds. Motion analysis data and surface electromyography (sEMG) were collected while participants performed the 30sCST. To quantify postural balance, the displacement of the center of mass (CoM) and the peak instantaneous velocity of the CoM were calculated. The kinematic data included forward lean angles of the trunk and pelvic, range of motion (RoM) of the hip, knee, and ankle joints in the sagittal plane. The averaged activation levels of gluteus maximus, vastus lateralis, vastus medialis, rectus femoris, biceps femoris (BF), tibialis anterior (TA), and medial head of gastrocnemius muscles were indicated by the normalized root mean square amplitudes.Results: Compared with the asymptomatic control group, the knee OA group prolonged the duration of the stand-to-sit task, demonstrated significantly larger CoM displacement and peak instantaneous CoM velocity in the anterior-posterior direction, reduced ankle dorsiflexion RoM, greater anterior pelvic tilt RoM, and lower quadriceps femoris and muscles activation level coupled with higher BF muscle activation level during the stand-to-sit task.Conclusion: This study indicates that individuals with knee OA adopt greater pelvic forward lean RoM and higher BF muscle activation level during the stand-to-sit task. However, these individuals exist greater CoM excursion in the anterior-posterior direction and take more time to complete the task. This daily functional activity should be added to the rehabilitation goals for individuals with knee OA. The knee OA group performs reduced ankle dorsiflexion RoM, quadriceps femoris, and TA activation deficit. In the future, the rehabilitation programs targeting these impairments could be beneficial for restoring the functional transfer in individuals with knee OA.

“…The primary hip abductor, gluteus medius, is one of the muscles that stabilizes the pelvis while walking (1) . Hip abductors were observed to be engaged during walking, particularly on the stance limb (2) . There is an anatomical relationship between the hip abductors and rectus abdominis, oblique abdominis and quadratus lumborum.…”

Background: Hip abductors muscles are extremely important during several activities and its weakness can affect our daily life activities. Objective: This study aimed to investigate the effect of strengthening trunk muscles on Hip abductors strength and endurance in young adults. Patients and methods: This study was conducted on 58 patients. They were assigned into 2 equal groups: Group A (Control group) consisted of 29 subjects received conventional hip abduction exercises from standing position against a theraband and group B (Study group) consisted of 29 subjects received the same hip abduction exercises plus a curl up exercise performed 3 days a week at October University for Modern Sciences and Art (MSA). Results: There was statistically significant differences in the mean values of maximum abductor isometric strength post-study between both groups (p= 0.038) in favor of group B, in the mean values of time of unilateral bridging test post-study between both groups (p= 0.046) in favor of group B and in the mean values of time of hip abductor endurance post-study between both groups (p= 0.005) in favor to group B. Conclusion: Curl up exercise combined with hip abduction resisted exercise against an elastic band did a significant improvement regarding the maximum hip abductors isometric strength, and there was a significant difference in Hip abductors endurance compared to doing just hip abductors resisted exercise only. It's recommended to add curl up exercise in programs aimed to improve Hip abductors strength and endurance.
