The present study aimed to evaluate and compare the feedback and feedforward activaties of selected lower limb muscles during triple jump spike with and without toe-in landing in female volleyball players. Methods: In this controlled-laboratory study, 15 female elite volleyball players performed triple spike in toe-in and neutral positions. The electrical activity of tibialis anterior, proneus longus, gastrocenemius, vastus medialis, vastus lateralis, semitendinosus, and biceps femoris muscles was recorded using a 16-channel surface electromyography device (Baya Med Company). The Dependent Samples t-test was applied to analyze the obtained data at the 95% confidence level. Results: In toe-in landing, the semitendinosus muscle activity (P=0.040) significantly decreased in the feedforward phase. Besides, in the feedback phase, there were significant increases in tibialis anterior (P=0.039) and proneus longus (P=0.043). Eventually, a significant decrease was observed in the medial gastrocenemius (P=0.042) and biceps femoris muscle (P=0.047) activities. Conclusion: Decreased biceps femoris muscle activity during the feedback phase with the toe-in position may be associated with the decreased supportive effect of hamstring muscle, increased anterior knee shear force, and subsequently anterior cruciate ligament injury. Increased activity of leg and ankle muscles may also increase the odds of muscular fatigue and subsequent ankle sprain during toe-in landing.

The purpose of this study was to determine whether the change in the positions of hip rotation and applying isometric hip external rotation during pelvic drop (PD) can affect muscles activity in subjects with GVD. A total of thirty recreational female athletes with (n = 15) and without (n = 15) GVD participated in this study. Surface electromyography measured Gmed, tensor fascia latae (TFL), and quadratus lumborum (QL) muscles activity when subjects performed PD in three different positions of hip rotations with and without applied isometric hip external rotation force. There were differences in muscle activity between GVD and healthy subjects. The Gmed/TFL and Gmed/QL muscles activity ratio altered while placing the hip in different rotation positions and applying isometric load. The lower extremity muscles’ activity is affected by GVD, and changing the p...

Therefore, the aim of the present study was to determine the effect of band loop on kinematic and electromyography of lower extremities during pedaling. Materials and Methods: In this descriptive study, Kinematic information of the lower extremity and the electromyographic activity of muscles of 30 male students (normal=15, Genuvarum (GV)=15) in the Movafaghian Clinic in Tehran were recorded during pedaling with and without band loop in 10 pedaling cycles of last 30 seconds. Independent t-test and paired t-test were used to analyze the data. Results: The results showed a significant difference in the gluteus medius (Gmed) muscle activation (p=0.001) and Gmed/tensor fasciae latae (TFL) activity ratio in both groups (normal p= 0.042, GV p= 0.045), onset of TFL (p=0.007) and offset of Gmed activity (p=0.018) in the normal group, and the onset of Gmed muscle (p=0.048), offset of Gmed (p=0.047) and mean knee abduction angle (p=0.047) in the GV group. Also, the results showed a significant difference in TFL activation with and without the loop across the two groups (with loop p= 0.001, without loop p= 0.003) and the mean (p=0.021) and maximum knee abduction angle (p=0.027) without loop between the two groups. Conclusion: Pedaling with loop band can be an effective method to increase the function and activation of Gmed muscle while decreasing TFL, improving knee kinematics in the frontal plane and knee stability to prevent injury in the normal and GV groups.

A fundamental first step was the development of an improved CLLJ detection algorithm to provide more accurate positive results. The analysis of the Benguela CLLJ was performed initially at a global scale, including the other CLLJ regions, using an ensemble of reanalyses at 0.7 o. It was shown that the Benguela CLLJ occurs along the entire year and is characterized by a spatial displacement with two local maxima where the Benguela CLLJ is more frequent (-26 o S and-17.5 o S). Nonetheless, a more detailed analysis was needed to understand the physical mechanisms behind the occurrence of this coastal jet. The analysis of the present climate and future projections was done through dynamical downscaling at high resolution (25 km) with uncoupled and coupled atmosphere-ocean simulations. At a regional scale the importance of the local forcing in enhancing the frequency of occurrence of the Benguela CLLJ, particularly when the coastal jet is located more north, was shown. Under a warming climate, the frequency of occurrence and intensity of the Benguela CLLJ is projected to increase due to the changes in the St. Helen High, which intensifies the flow offshore the west coast of South Africa, and due to the intensification of the land-sea thermal contrasts. However, during spring, associated to the decrease in near-surface wind speed due to higher SSTs, the frequency and intensity of the Benguela CLLJ is expected to decrease near-17.5 o S. The wind resource in the Southwestern African offshore region was analysed and revealed great potential in present and future climates, particularly in the areas where the Benguela CLLJ occurs.

The majority of studies on the snake parasites were focused on zoonotic helminths with the public health concern. As nematodes detected from the snake hosts, Kalicephalus natricis and 2 species of larval Gnathostoma, i.e., G. hispidum and G. nipponicum, were reported in Korea so far . G. hispidum was found in the viper snake (Gloydius brevicaudus) [4], and G. nipponicum was found in the Asian tiger keelback snake (Rhabdophis tigrinus) as well as the red-tongued viper snake (G. ussuriensis) . Both species of Gnathostoma larvae can induce zoonosis. On the other hand, K. natricis detected in the intestine of Asian tiger keelback snake was described as a nonzoonotic nematode . In the present study, we describe additional 3 non-zoonotic nematode species from snakes, i.e., Kalicephalus brachycephalus, Kalicephalus sinensis, and Ophidascaris excavata, recovered from Korean terrestrial snakes in the faunistic point of view. The Chungnam Wild Animal Rescue Center (CWARC) and Korea Broadcasting System (KBS) donated the snakes to Parasite Resource Bank, Korea National Research Resource Center, the Republic of Korea (PRB) in July 2014 and February 2015, respectively. The host identification and scientific name were based on the reference, 'Ecological Guide Book of Herpetofauna in Korea' and 'National List of Species of Korea (Vertebrates) ' [8,9]. A red-banded snake (Dinodon rufozonatm), a dione rat snake (Elaphe dione), and a viper snake (G. brevicaudus) that were collected from Nonsan-si (City) were donated by CWARC. The Programming Department of Korea Broadcasting System (KBS) donated 2 Asian tiger keelback snakes (R. tigrinus) and an Amur rat snake (Elaphe schrenckii) to PRB for examination of sparganum infections. These snakes were collected from the northern region of Chungcheongbuk-do (Province). The snakes were all confiscated from illegal hunters. The snake carcasses donated by the CWARC were preserved at -20˚C in a freezer until examination. The other snakes were donated alive and were euthanized with chloroform anesthesia immediately before decapitation and examination for parasites. The entire bodies of the snakes were skinned, and the skins were searched for spargana visually without magnification. The viscera were separated by organs, which were opened and washed in warm water. This washed material was filtered through 200 µm sieve, and methods of sedimentation were used to recover the parasites.

Better and more comprehensive recognize of effective factors on quality of balance and how they impress, provide the opportunity which helps to improve motor-base factors in whole life and avoids negative impacts. It seems that anatomical abnormalities such as flat and pescavus foot and morphologic features of the foot can affect motor fitness characteristics like balance. So, this research aimed to compare the static and dynamic balance of women college athletes which have different foot arch heights. Materials and Methods: Static and dynamic balance were assessed in 90 women athletes in three types of foot arch: flat foot (30 persons), pescavus foot (30 persons) and normal foot (30 persons); it was done using stabilometer device with open-eye participant and maintaining a single leg stance (a measure of static balance), while dynamic balance was tested with putting a dominant step on a device (a measure of dynamic balance). Besides, to differentiate between flat, pescavus and normal foot arch, the navicular drop was tested with Brady attributive method. To test and analyze statistical datum, also one-way ANOVA statistical method was used via SPSS19 software. Results: There was a significant difference in total area of the swing movement (P = 0.002) in static balance; however, there is not any significant difference between the study groups in dynamic balance (P = 0.098). Conclusion: Although static balance in person who suffers from flat and pescavus foot arch abnormality is lower than normal foot arch, but in dynamic balance, no significant differences between the three groups of foot arch height were noticed. So, the people who suffers from flat and pescavus foot arch should do their daily activities with more accuracy and attention.
