the purpose of the present study was to determine the effect of four weeks of detraining after 12 weeks of continuous and intermittent aerobic training on high sensitive c-reactive protein (hs-crp) in rats (325.6±4.93 grams and 21 months old and their fertility period expired 3 months ago). for this purpose, 80 female wistar rats with strain 14848 were prepared and divided into three groups: co...

Unaccustomed eccentric exercise is a well-documented cause of exercise-induced muscle damage. However, in trained subjects muscle injury involves only light or moderate tissue damage. Since trained rats are widely used as a model for skeletal muscle injury, here we propose a semiquantitative scoring tool to evaluate muscle damage in trained rats. Twenty male Sprague-Dawley rats were trained for...

We investigated the osteogenic responses to jump training and subsequent detraining in young and adult male rats to test the following hypotheses: 1) jump training has skeletal benefits; 2) these skeletal benefits are preserved with subsequent detraining throughout bone morphometric changes; and 3) there are no differences between young and adult rats during detraining in terms of the maintenan...

OBJECTIVES To assess the effects of short (six weeks) and long (52 weeks) term detraining on functional fitness in elderly people, and to determine whether these effects differ according to age in elderly people. METHODS Elderly subjects, aged 60-86 years, completed a nine week multicomponent exercise training programme. They performed the senior fitness test after six and 52 weeks, and the r...

Physiol. 222(4) : 836-840. 1972.~Sixweek-old guinea pigs have nearly 12,000 fibers per plantaris cross section. With aging, some 2,700 fibers were lost. Daily endurance running prevented the loss of fibers and fibers were smaller. Trained animal...
