Adenosine-5'-triphosphate (ATP) supplementation improves low peak muscle torque and torque fatigue during repeated high intensity exercise sets
BACKGROUND Intracellular concentrations of adenosine-5'-triphosphate (ATP) are many times greater than extracellular concentrations (1-10 mM versus 10-100 nM, respectively) and cellular release of ATP is tightly controlled. Transient rises in extracellular ATP and its metabolite adenosine have important signaling roles; and acting through purinergic receptors, can increase blood flow and oxygen...
متن کاملPeak torque and rate of torque development in elderly with and without fall history.
BACKGROUND Falls are one of the greatest concerns among the elderly. A number of studies have described peak torque as one of the best fall-related predictor. No studies have comprehensively focused on the rate of torque development of the lower limb muscles among elderly fallers. Then, the aim of this study was to determine the relationship between muscle peak torque and rate of torque develop...
متن کاملEffects of fatigue on the torque-velocity relation in muscle.
BACKGROUND The extent to which fatigue is related to the velocity of shortening is still not fully understood. OBJECTIVES To examine the effects of fatigue induced by maximal intensity exercise at different velocities on subsequent torque-velocity relations in muscle. METHODS Ten men (mean (SD) age 25 (3) years; stature 1.78 (0.34) m; body mass 80.6 (14.5) kg) provided written informed cons...
متن کاملEvoked EMG-based torque prediction for muscle fatigue tracking and closed-loop torque control in FES
Functional electrical stimulation (FES) is a potential technique to provide active improvement to spinal cordinjured (SCI) patients in terms of mobility, stability and side-effect prevention. FES-elicited muscle force is requiredto be appropriate and persistent to perform intended movement or maintain a posture balance. However, musclestate changes such as muscle fatigue degrade...
متن کاملHematological Alterations in Albino Rats after Administration of Honeybee Venom
Bee venom is a complex mixture of proteins (enzymes and peptides) with unique pharmacological activities. The main enzymes in bee venom are hyaluronidase and phopholiphase A2. Melittin in high concentrations also has caused hemolysis of red blood cells. This study was conducted to evaluate effects of honeybee venom on hematological characteristics of albino rats. Rats were divided in 3 groups v...
