Effects of exercise training on dendritic morphology in the cardiorespiratory and locomotor centers of the mature rat brain.

It has been shown that dendritic branching in neural cardiorespiratory and locomotor centers can be attenuated with exercise training (ET) initiated immediately after weaning. The purpose of this study was to determine whether neuroplastic changes occur within cardiorespiratory and locomotor centers due to ET after maturation. Male Sprague-Dawley rats (21 days old, n=28) were individually housed in standard cages.

Salicylate-based analgesic balm attenuates pressor responses from skeletal muscle.

Purpose: Analgesic balms (AB) are widely used in sports medicine. We previously have examined effects of various counterirritant-based AB on pressor responses evoked by muscular contraction (MC), mediated by group III and IV muscle afferents known to produce exercise and nociceptive responses. Our purpose was to examine trolamine salicylate-based analgesic balm (TS) effects.

Reversibility of exercise-induced dendritic attenuation in brain cardiorespiratory and locomotor areas following exercise detraining.

It has been shown previously that dendritic branching in cardiorespiratory and locomotor brain areas can be attenuated with exercise training (ET). It was not known whether this process was reversible. Twenty-three (n = 23) male Sprague-Dawley rats were individually caged and divided into two groups: untrained (UN; n = 11) and detrained (DTR; n = 12).

Neuroplastic adaptations to exercise: neuronal remodeling in cardiorespiratory and locomotor areas.

Neuronal activity has been shown to be attenuated in cardiorespiratory and locomotor centers of the brain in response to a single bout of exercise in trained (TR) vs. untrained (UN) animals, but the mechanisms remain obscure. Based on this finding, dendritic branching patterns of seven brain areas associated with cardiorespiratory and locomotor activity were examined in TR and UN animals.

Effects of a menthol-based analgesic balm on pressor responses evoked from muscle afferents in cats.

Objective: To evaluate changes in heart rate (HR) and mean arterial pressure (MAP) as indicators of changes in pressor response for muscle afferents after topical application of menthol (MEN)-based analgesic balm.

Animals: 11 decerebrate cats.

Procedure: Pressor responses were reflexively evoked by static contraction of hind limb muscles, which are caused by group III and IV afferents.

Capsaicin-based analgesic balm decreases pressor responses evoked by muscle afferents.

Unlabelled: Capsaicin-based analgesic balm decreases pressor responses evoked by muscle afferents. Physically active individuals use countless analgesic balm (AB) products with various active ingredients daily. Despite this, few studies have investigated the mechanism of action and efficacy of AB.
