The influence of myosin regulatory light chain phosphorylation on the contractile performance of fatigued mammalian skeletal muscle
… without a significant metabolic cost. Twitch force was potentiated to a greater extent in wildtype muscles until peak force had diminished to ~60% of baseline (37.2 ± 0.05% vs. 14.3 ± 0.02%). Despite no difference in peak force (Po) and shortening velocity (Vo), rate of force development …

Textural and Physical Properties of Fat-Free Turkey-Beef Frankfurters: Effects of Non-Meat Ingredients and End-Point Temperature
… (P< 0.05) penetration values (total energy and peak force) but higher shear stress and shear strain. In addition, higher salt levels resulted in lower cooking loss, moisture content, protein content, and darker frankfurters. Increasing AW level reduced (P<0.05) penetration values (total energy …

Age Related Differences in Motor Output Variability During Isometric, Concentric and Eccentric Quadriceps Femoris Muscle Contractions
… (MVC) and control submaximum levels of force during continuous isometric, discrete isometric, discrete concentric and discrete eccentric contractions of the quadriceps femoris. Of particular interest was to model variability of force during continuous and discrete isometric contractions. …

Measuring the fracture energy of bed breakage using a short impact load cell
… each variable was investigated by evaluating the peak forces obtained, the particle fracture energy and the degree of particle breakage attained. For both ores it was found that the peak force increased linearly with increasing steel ball mass and drop height, and it was found that the drop height …

Dynamic Strength Index and Countermovement Jump Performance in Female and Male Collegiate Basketball Athletes Across a Competitive Season
… Index (DSI), calculated as the ratio of CMJ peak force to IMTP peak force, offers insight into the strength–power profile of athletes and may inform individualized training approaches. However, limited research exists on seasonal changes in DSI, CMJ metrics, and joint kinematics in basketball …
