Abstract
In the quest to maximize average propulsive stroke impulses over 2000-m racing, testing and training of various strength parameters have been incorporated into the physical conditioning plans of rowers. Thus, the purpose of this review was 2-fold: to identify strength tests that were reliable and val...

Abstract
Exercising at levels of whole body accelerations exceeding 3.6g has been shown to have positive effects on cardiovascular fitness, bone density and balance. This pilot research project evaluated the whole body accelerations and cardiovascular challenge provided by selected walks in the Canberra regio...

Abstract
UPDRS and PDQ-39 are reliable and valid assessments of quality of life and physical function in persons with Parkinson's disease (PD). However, these measures were not designed to track day-to-day or week-to-week changes in community activity in persons with PD.
Twelve individuals with PD (stage 1 t...

Abstract
We used the body mass index (BMI) and percentage of body fat as indicators of obesity and estimated the maximal oxygen consumption (VO(2max)) during exercise as an indicator of physical fitness. We divided these variables into quintiles. We examined the single effect and interactions of the obesity...

Abstract
During peak exercise HR, stroke volume and cardiac output were not different between the groups with and without diabetes; however, forced expiratory flow at 50% of the forced vital capacity was lower in subjects with diabetes (P < 0.05). Within the group with diabetes, HbA1c was lower in the low-Hb...

Abstract
We developed the hybrid training method (HYB) as a countermeasure of this musculoskeletal atrophy, which uses the contraction produced in a muscle by electrical stimulation of antagonist to resist the volitional contraction of agonist. HYB has several features. These include ; 1) simple device, 2) s...

We examined whether an acute endogenous metabolic acidaemia had a similar effect. Six subjects completed two tests (A, B), each comprising two 6-min bouts separated by a 6-min "0" W recovery: A:- 90% thetaL, 90% thetaL; B:- supra-thetaL (50% between thetaL and peak V'O2), 90% thetaL. For Protocol A,...
