A Nonadapted Cardiac Autonomic Regulation Following Repeated Bouts Of Eccentric Exercise

Influence of repeated bouts of eccentric exercise on high-intensity aerobic performance

[Purpose] It is believed that eccentric high-intensity exercise can decrease performance in subsequent exercise. However, with repetition, the deleterious effects can be minimized. Thus, this study evaluated the influence of repeated bouts of eccentric exercise on subsequent high-intensity aerobic performance. [Subjects and Methods] Seven healthy and sedentary male volunteers were recruited. a)...

Impact of Repeated Bouts of Eccentric Exercise on Skeletal Muscle Morphology and Myogenic Gene Expression

Cardiac autonomic regulation during hypoxic exercise.

AUTONOMIC NERVOUS SYSTEM REGULATION of the heart and vasculature plays a key role in enabling the tight coupling between oxygen consumption of exercising skeletal muscles and oxygen delivery. The withdrawal of cardiac parasympathetic nerve activity and elevation in cardiac sympathetic nerve activity facilitate the exercise intensity-dependent increase in heart rate, ventricular contractility, s...

HIGHLIGHTED TOPIC Eccentric Exercise A contralateral repeated bout effect attenuates induction of NF- B DNA binding following eccentric exercise

Xin L, Hyldahl RD, Chipkin SR, Clarkson PM. A contralateral repeated bout effect attenuates induction of NFB DNA binding following eccentric exercise. J Appl Physiol 116: 1473–1480, 2013. First published August 15, 2013; doi:10.1152/japplphysiol.00133.2013.—We investigated the existence of contralateral repeated bout effect and tested if the attenuation of nuclear factor-kappa B (NFB; an import...

The α₇β₁-integrin increases muscle hypertrophy following multiple bouts of eccentric exercise.

Mechanical stimuli increase skeletal muscle growth in a mammalian target of rapamycin (mTOR)- and p70(S6K)-dependent manner. It has been proposed that costameric proteins at Z bands may sense and transfer tension to these initiators of protein translation, but few candidates have been identified. The purpose of this study was to determine whether a role exists for the α(7)-integrin in the activ...
