Hydration Status and Perception of Fluid Loss in Male and Female University Rugby Union Players.

Rugby union players are at risk for dehydration due to the high physiologic demand of the sport (~7.5 MJ/game). Dehydration could be due to lack of knowledge of fluid lost during activity.

Increased endothelin and creatine kinase after electrical stimulation of paraplegic muscle.

The purpose of this study was to assess changes in creatine kinase (CK) and endothelin (ET) in individuals with spinal cord injury (SCI) after computerized functional electrical stimulation leg ergometry (CFES LE). Eight subjects (7 male and 1 female) with complete spinal cord lesions (C7 to L1) completed zero-loaded CFES LE tests at baseline, after 3, 6, and 12 wk of CFES LE training (30 min, 3 times/wk), and also after detraining (DT) (n = 5). Venous blood samples were drawn 24, 48, and 72 h after CFES LE for measurement of ET and CK.

Effects of electrical stimulation and upper body training after spinal cord injury.

The purpose of this study was to measure the cardiorespiratory improvements during the initial weeks of training in individuals with spinal cord injury (SCI). Eight adult volunteers (ages 23-41) with paraplegia (T4-L1, N = 7) and low levels of quadriplegia (C7, N = 1) participated in a 12-wk training program consisting of 6 wk of computerized functional electrical stimulation leg ergometry (CFES LE) followed by 6 wk of combined arm ergometry and CFES LE (hybrid ergometry; HE). Measures of peak oxygen consumption (pV02) and immediate post-exercise blood lactate (La-) were collected during an intermittent CFES LE graded exercise test (3-min stages; 1/8-kp increments) prior to training (0T), following 6 wk of CFES LE training (6T) and following 6 wk of HE training (12T).

A dynamic balance measure for persons with severe and profound mental retardation.

The present study's purpose was to probe into the reliability and validity measurement of dynamic balance for individuals with IQs below 29. The 91 subjects were asked to complete the Papcsy-DePaepe test and the Bruininks test according to each test's protocol. Correlations of odd-even scores produced a reliability of .

A critique of therapeutic intervention programming with reference to an alternative approach based on motor learning theory.

As an alternative to current therapeutic intervention programming for developmentally delayed children, a rationale for intervention programming based on theories of motor control and learning is presented. The authors believe that the keys to successful motor training programs are repetition, correctly performed practice of functional skills, and sufficient learning time to facilitate skill retention and transfer. In order for therapists to construct and implement the most appropriate motor training programs for developmentally delayed children, they must be knowledgeable of the sensory-motor basis of motor skill acquisition.
