  • The purpose of this study was to investigate the differences in upper and lower strengths and symmetry between upper body injury group, lower body injury group and non-injury group of bowling athletes. The subjects were the upper body injury group (UG), n = 16, the low body injury group (LG), n = 8, the non injury group, [NG], n = 15). The isometric strength of the bowler was measured using Manual Muscle Tester 01165 (Lafayette Instrument Company, USA) and the symmetry index (SI) was calculated. The results were as follow. The symmetry index of hip extension strength and hip external rotation strength was statistically larger in NG than LG (p <.05). The above results suggest that lower body strength and bilateral symmetry was closely related to injuries of the lower body. In order to prevent injury of the bowler, strengthening of lower body strength and symmetrical training are needed.

  • Background: The present study was conducted with 30 adult males in order to examine the muscle activity of the trunk and the lower extremities at diverse initial bending angles of the hip joint during bridge exercise on a stable surfaces and on an unstable surface that is widely performed for stabilization. Methods: The initial angles of the hip joint used were $0^{\circ}$, $45^{\circ}$ and $90^{\circ}$ and the subjects were divided into a matt experimental group and a balance training group. Results: In maximum values of muscle activity at different exercise methods and angles, the matt experimental group showed statistically significant differences in the muscle activity values of the rectus abdominis muscle, the erector spinae muscle, the rectus femoris muscle and the peroneus muscles between different angles while the balance training group showed significant differences only in the muscle activity values of the erector spinae muscle between different initial angles of the hip joint. The matt experimental group showed significant differences in muscle activity between initial angles $0^{\circ}$ and $90^{\circ}$, between $45^{\circ}$ and $90^{\circ}$ in the rectus abdominis muscle, between $0^{\circ}$ and $90^{\circ}$ in the erector spinae muscle, between $45^{\circ}$ and $90^{\circ}$ in the rectus femoris muscle and between $0^{\circ}$ and $90^{\circ}$ in the peroneus muscles while the balance training group showed significant differences between $0^{\circ}$ and $90^{\circ}$ in the erector spinae muscle. Conclusions: Therefore, it is thought that bridge exercises should be applied to patients using diverse methods.

  • Purpose : The aim of this study was to compare the effects of the abdominal draw-in exercise (ADIE) and the dead bug exercise (DBE) on the pelvic anterior tilt angle and the activities of the gluteus maximus (GM), erector spinae (ES), and semi tendinosus (ST) during prone hip extension. Methods : A total of 22 female adults with weak abdominal muscles were divided into two groups: ADIE group (n=11) and DBE group (n=11). The muscle activities of the GM, ES, and ST along with the pelvic anterior tilt angle during prone hip extension were measured using a wireless surface electromyograph and gyro sensor before performing the prescribed exercise. Two groups conducted the assigned exercise for 10 minutes. After the exercise, their muscle activities and the pelvic anterior tilt angle were equally re measured. Results : In the DBE group, the muscle activity of GM was significantly increased after the intervention (p<0.05). However, there was no significant difference between the two groups in the amount of increase in the activity of GM (p>0.05). Moreover, in both groups, the activity of ES and the pelvic anterior tilt angle decreased significantly after the intervention (p<0.05) The decreased quantity in the pelvic anterior tilt angle and in the activity of ES showed no difference between the two groups (p>0.05). In the activity of ST, there was no significant difference within and between the two groups (p>0.05). Conclusion : Therefore, we suggest that ADIE and DBE are effective for women with weak abdominal muscles since the ES activity and pelvic anterior tilt angle are reduced during prone hip extension.

  • Purpose: This study investigated the three-dimensional moment values of the hip joint for subjects with artificial leg length alterations and subjects with unaltered leg lengths. Methods: Forty-two healthy adults (8 men, 34 women) participated in this study. The selected subjects were able to walk normally, had less than a 1 cm leg length discrepancy, and were instructed to wear shoes that fit their feet. The study participants performed 8 dynamic gait trails to measure the hip joint moment using a three-dimensional motion analysis system. Kinetic and dynamic three-dimensional gait analysis data were collected from infrared cameras, and a force plate was used to standardize the weight of each subject. Results: There were significant correlations between the differences in the leg length discrepancy during right extension, right flexion, right internal rotation, and left extension in hip joint moments (p<0.05). There were significant correlations between the differences in shoe conditions during left extension, right flexion, right extension, and right internal rotation in the hip moments (p<0.05). Conclusion: This study suggests that a leg length discrepancy can affect hip joint moment, which may further exacerbate musculoskeletal disorders, such as osteoarthritis in lower extremity joints. Therefore, further studies should be conducted to verify the impact of clinical interventions on differences in hip joint moment values to correct leg length discrepancies and prevent osteoarthritis in lower extremity joints.

  • Purpose : The aim of this study was to investigate the effects of the abdominal draw-in (ADI) exercise on the onset times of the gluteus maximus (GM) and erector spinae (ES) as well as the pelvic anterior tilt angle during prone hip extension (PHE). Methods : A total of 24 female adults were divided into two groups: those with normal abdominal muscles (n=12) and those with weak abdominal muscles (WAM; n=12). Before the intervention, the onset times of the GM and ES along with the pelvic angle during PHE were measured. Subsequently, the participants conducted the ADI exercise for 10 minutes. After conducting the ADI exercise, the onset times and the pelvic angle were re-measured. Results : In the pre-intervention comparison between the two groups, the WAM group showed faster ES onset times and higher pelvic angle than the normal group (p<0.05). In the WAM group, the ES onset times were significantly delayed after the ADI exercise (p<0.05). In both groups, the pelvic angle was significantly decreased after the ADI exercise (p<0.05). The decrease in the pelvic angle was significantly greater in the WAM group than in the normal group (p<0.05). The GM onset time was found to be not significant in all comparisons (p>0.05). Conclusion : Therefore, it can be concluded that after performing the ADI exercise, the pelvic anterior tilt during PHE is decreased in normal women and those with WAM, especially in the WAM group, suggesting that the ADI exercise can reduce the compensatory pelvic anterior tilt more effectively by delaying the ES onset times.

  • Purpose : The study investigated the effects of Pilates exercise on strengthening trunk muscles of females who perform such exercise for the purpose of comparing activation of trunk muscles that contact while performing Pilates motions between females with or without at least 8 weeks of Pilates experience. Methods : The study investigated 10 females with at least 8 weeks of Pilates experience in the past 6 months (experienced group) and 10 healthy females without Pilates experience (non-experienced group). The study used basic Pilates postures involving hip abduction, lift, and leg swing motions as the measurement postures in comparing the activation of muscles used for stabilization, such as the rectus abdominis, external oblique abdominal, and transverse abdominis & internal oblique abdominal muscles. Surface electromyography was used for measuring muscle activation, and the measurements targeted activation of the rectus abdominis, external oblique abdominal, transversus abdominis, and internal oblique abdominal muscles. Results : The study results showed that, as compared to the non-experienced group, the experienced group had significantly higher muscle activation in the transverse abdominis and internal oblique abdominal muscles during hip abduction (p<.05) and significantly higher muscle activation in the rectus abdominis, external oblique abdominal, and transverse abdominis & internal oblique abdominal muscles during lift and leg swing motions (p<.05). Conclusion : Pilates exercise performed over a long period can be recommended as an effective exercise method that can increase the activation of trunk muscle, and especially, repeated performance of highly difficult motions can increase muscle activation even more, which can help promote spinal stabilization, prevent pain, and improve performance of activities of daily living.

  • Purpose: Patients with tibial fractures can have functional problems with balance and gait, as well as lower extremity muscle weakness. This case report aimed to describe the effect of hip joint strengthening exercises using proprioceptive neuromuscular facilitation (PNF) on balance and gait and lower limb function in a patient with tibia fracture. Methods: One patient diagnosed with tibial fracture was treated for seven weeks with the basic procedure, pattern, and technique of PNF for a hip joint strengthening exercise. Results: The results of pre- and post-intervention treatment showed improvements in physical function and structure in the clinical tests, including the manual strength test; the modified Ashworth scale; sensory evaluation; balance, sit-to-stand, and gait performance; and evaluation of lower limb function. Conclusion: Based on the results of this study, it is suggested that the use of theory-based proprioceptive neuromuscular stimulation for hip joint strengthening exercises positively affects patients' functional improvement in tibial fracture patients, and this may be used as a therapeutic exercise method for those with orthopedic problems in the lower extremities. One limitation of this study was that it was performed on only one tibia fracture patient, which makes it difficult to extend the treatment effects to all patients with this condition.

  • Purpose: The purpose of this study was to investigate the effects of plank exercises involving the contraction of the adductor muscle of the hip joint on core muscle thickness and to propose an effective plank exercise method. Methods: A total of 30 healthy young adults (17 males, 13 females) voluntarily participated in the study. The subjects were randomized to the prone plank exercise with hip adductor contraction (n=10), the prone plank exercise (n=10), and the supine plank exercise (n=10) groups. Muscle thickness measurements were taken prior to starting the exercise program and after completing the program at the end of a 4-week period. The muscle thickness of the rectus abdominis (RA), multifidus (MF), external oblique (EO), internal oblique (IO), and transverse abdominis (TrA) muscles were measured using ultrasonography. Each group performed the stipulated plank exercise five times a week as follows: 5 sets of 20 seconds during the first week, 5 sets of 30 seconds in the second week, 5 sets of 40 seconds in the third week, and 5 sets of 40 seconds in the last week. Results: The three different types of plank exercises all showed significantly increased thickness of the RA, MF, EO, IO, and TrA (P<0.05). Furthermore, changes in the thickness of both the MF and TrA were statistically more significant in the groups that did the prone plank exercise with the hip adductor contraction and the supine plank exercise than in the prone plank exercise group (P<0.05). Conclusion: The study results suggest that the prone plank exercise with hip adductor contraction is a more effective method for overall activation of the RA, MF, EO, IO, and TrA than the prone plank exercise and the supine plank exercise.

  • Purpose: The purpose of this study was to determine the effects of contract relaxation and a combination of isotonics in proprioceptive neuromucular facilitation (PNF) on hip and lumbopelvic motions of male patients with chronic low back pain. Methods: As the subjects of this study, a total of 45 male patients with chronic low back pain were divided into groups: 15 who underwent contract relaxation (CR) of the PNF of their hip joints, 15 who underwent a combination of isotonics (CI) of the PNF, and 15 who underwent both techniques. A device for analyzing three-dimensional motion was used to measure hip medial rotation angles, lumbopelvic rotation angles, and hip medial rotation angles at the start of lumbopelvic rotation during hip medial rotation. A two-way repeated measures ANOVA was used to compare the average values. Results: There were interactions in the hip medial rotation angles, lumbopelvic rotation angles and hip medial rotation angles at the start of lumbopelvic rotation based on the methods and periods of exercise (p < 0.05). The CR and the CR+CI groups displayed more increased hip medial angles when compared to the CI group. The CR+CI group had more decreased lumbopelvic rotation angles when compared to the CR and the CI groups. The CR+CI group had more increased hip medial rotation angles at the start of lumbopelvic rotation when compared to the CR and the CI groups. Conclusion: It can be concluded that the combination of stretching and stability exercises was effective in male patients with chronic low back pain who showed limited hip medial rotation.
