(1) Background: this study aimed to determine if there are differences in quadriceps and hamstring muscle activation professional male female soccer players. (2) Methods: was recorded by surface electromyography 27 players (19 8 female). The performed the Bulgarian squat lunge exercises. Vastus medialis, vastus lateralis, rectus femoris, semitendinosus, biceps femoris were muscles analyzed. (3)...

BACKGROUND The echogenicity patterns of ultrasound scans contain information of tissue composition in muscles. The aim was: (1) to develop a quantitative ultrasound image analysis to characterize tissue composition in terms of intensity and structure of the ultrasound images, and (2) to use the method for characterization of ultrasound images of the supraspinatus muscle, and the vastus laterali...

Arteri subscapularis merupakan salah satu arteri yang berlokasi di ekstremitas superior, sisi posterior dinding toraks. Pembuluh A. cabang besar dari axillaris berfungsi untuk mengalirkan darah ke kulit dan otot. Variasi pada memiliki makna penting karena berbagai operasi ortopedi melibatkan bahu. ini dapat menyebabkan risiko kesalahan dalam operasi, mengancam ekstremitas. Tujuan studi adalah m...

After Luciola praeusta Kiesenwetter 1874, Asymmetricata circumdata (Motschulsky) is the second Indian species of firefly identified recently. Here we present steady-state and time-resolved measurements of bioluminescence emissions of male specimens of this new-found species. Steady-state spectra recorded in a high-resolution spectrometer show the peak wavelength at 570 nm, while the same on a c...

Background: Bioluminescence in fireflies and click beetles is produced by a luciferase-luciferin reaction. The luminescence property and protein structure of firefly luciferase have been investigated, and its cDNA has been used for various assay systems. The chemical structure of firefly luciferin was identified as the D-form in 1963 and studies on the biosynthesis of firefly luciferin began ea...

Objective To investigate associations between running speeds and contraction times in 8- to 13-year-old children. Method This longitudinal study analyzed tensiomyographic measurements of vastus lateralis and biceps femoris muscles' contraction times and maximum running speeds in 107 children (53 boys, 54 girls). Data were evaluated using multiple correspondence analysis. Results A gender differ...

[Purpose] This study investigated the effects of the slow speed-targeting squat exercise on the vastus medialis oblique/vastus lateralis ratio. [Subjects] Ten asymptomatic men were recruited. [Methods] The EMG activities of the vastus medialis oblique and vastus lateralis muscles were recorded using surface electrodes. The subject performed the squat exercise under 3 different conditions. [Resu...
