We evaluated the reliability of static and dynamic lumbar muscle endurance measurements on a BackUP lumbar extension dynamometer. Sixteen healthy participants (8 male; 8 female) volunteered for this investigation. Fifty percent of each participant's body weight was calculated to determine the weight load utilized for the static (holding time) and dynamic (repetitions) lumbar extension endurance...

Equivocal findings exist on the effect of concurrent strength (S) and endurance (E) training on endurance performance and muscle morphology. Further, the influence of concurrent SE training on muscle fiber-type composition, vascularization and endurance capacity remains unknown in top-level endurance athletes. The present study examined the effect of 16 weeks of concurrent SE training on maxima...

Physical exercise is used for the promotion and maintenance of good health and for the improvement of physical fitness. Both endurance and resistance exercises are needed to carry out a complete training program. Because time may be a barrier to physical exercise practice, the aim of this study was to verify whether the order of execution of endurance and resistance exercises, in concurrent tra...

Background: Several tests have been suggested to assess the isometric endurance of the cervical flexor (NFME) and extensors (NEE) muscles. This study proposes to determine whether neck flexors endurance is related to extensor endurance, and whether cervical muscle endurance is related to disability, pain amount and pain stage in subjects with neck pain. Methods: Thirty subjects (18 women, 12 me...

introduction: endurance training has significant effects on the renewal of heart tissue, including myosin heavy chain (mhc) proteins. on the other side, purine-rich element-binding protein β (purb) decreases the &alphamhc; gene expression. the aim of this study was to determine the impact of exercise endurance training on purb gene expression in the heart of wistar rats. methods: fourteen rats ...

We propose a new approach, called dynamic program and erase scaling (DPES), for improving the endurance of NAND flash memory. The DPES approach is based on our key finding that the NAND endurance is dependent on the erase voltage as well as the number of P/E cycles. Since the NAND endurance has a near-linear dependence on the erase voltage, lowering the erase voltage is an effective way of impr...

INTRODUCTION Pentraxin 3 (PTX3), which is mainly produced by endothelial cells, macrophages, and smooth muscle cells in the atherosclerotic region, has a cardioprotective effect. Endurance exercise training has also been known to offer cardioprotection. However, the effect of regular endurance exercise on PTX3 is unknown. This study aimed to investigate whether plasma PTX3 concentrations increa...
