Positive adaptations to weight-lifting training in the elderly.
Maximal weight-lifting performance, isometric strength, isokinetic torque, whole muscle and individual fiber cross-sectional areas, and muscle evoked contractile properties were assessed in 14 elderly males before and after 12 wk of weight-lifting training. Dynamic elbow flexion training of one arm resulted in a significant 48% mean increase in the maximal load that could be lifted once (1 RM) ...
متن کاملAdaptations of motoneuron properties to chronic compensatory muscle overload.
The aim of the study was to determine whether chronic muscle overload has measurable effect on electrophysiological properties of motoneurons (MNs), and whether duration of this overload influences intensity of adaptations. The compensatory overload was induced in the rat medial gastrocnemius (MG) by bilateral tenotomy of its synergists (lateral gastrocnemius, soleus, and plantaris); as a resul...
متن کاملChanges in motoneuron properties and synaptic inputs related to step training after spinal cord transection in rats.
Although recovery from spinal cord injury is generally meager, evidence suggests that step training can improve stepping performance, particularly after neonatal spinal injury. The location and nature of the changes in neural substrates underlying the behavioral improvements are not well understood. We examined the kinematics of stepping performance and cellular and synaptic electrophysiologica...
متن کاملUnilateral Purtscher-like retinopathy after weight-lifting.
PURPOSE To report a case of Purtscher-like retinopathy after weightlifting. METHODS A 17-year-old man presented with a sudden visual loss in his left eye after weightlifting two weeks ago. Fundus examination of the left eye showed cotton-wool spots and scattered retinal hemorrhages in the posterior pole. Fluorescein angiography and indocyanine green angiography with a scanning laser ophthalmo...
متن کاملThe Effect of Ramadan Fasting and Weight-Lifting Training on Plasma Volume, Glucose and Lipids Profile of Male Weight-Lifters
Objective(s) The purpose of the present study was to evaluate the effect of Ramadan fasting and weight-lifting training on plasma volume, glucose, and lipids profile of male weight-lifter. Materials and Methods Forty male weight-lifters were recruited and divided into 4 groups (n=10 each) and as the following groups: control (C), fasting (F), training (T) and fasting-training (F-T). The T an...
