Duration-controlled swimming exercise training induces cardiac hypertrophy in mice.
Exercise training associated with robust conditioning can be useful for the study of molecular mechanisms underlying exercise-induced cardiac hypertrophy. A swimming apparatus is described to control training regimens in terms of duration, load, and frequency of exercise. Mice were submitted to 60- vs 90-min session/day, once vs twice a day, with 2 or 4% of the weight of the mouse or no workloa...
متن کاملSwimming training increases cardiac vagal activity and induces cardiac hypertrophy in rats.
The effect of swimming training (ST) on vagal and sympathetic cardiac effects was investigated in sedentary (S, N = 12) and trained (T, N = 12) male Wistar rats (200-220 g). ST consisted of 60-min swimming sessions 5 days/week for 8 weeks, with a 5% body weight load attached to the tail. The effect of the autonomic nervous system in generating training-induced resting bradycardia (RB) was exami...
متن کاملSmall gene effect and exercise training-induced cardiac hypertrophy in mice: an Ace gene dosage study.
Small gene effects influence complex phenotypes in a context dependent manner. Here we evaluated whether increasing dosage of the angiotensin I converting enzyme (Ace) gene influence exercise-induced cardiac hypertrophy. Mice harboring one, two, three, and four copies of the Ace gene were assigned to sedentary (S1-4) and swimming exercise-trained (T1-4) groups (1.5 h twice daily, 5 days/wk, 4 w...

Background and Objective: In this study the effect of high intensity interval training on miR-29 expression that is expressed in the heart and in the regulation of physiological processes, including extracellular matrix and cardiac hypertrophy of healthy male rats were examined. Materials and Methods: 16 Wistar rats were divided into training (n=8) and control (n=8) groups. After one week of fa...
متن کاملEndurance Exercise Effects on Cardiac Hypertrophy in Mice
[Purpose] The purpose of this study was to investigate the effects of eight weeks of an endurance exercise training program on cardiac hypertrophy in mice. [Subjects] Male 129 SvJ/C57BL6 mice (n=12) were used. The exercised mice ran on a motor-driven treadmill five days per week for 40 minutes at a speed of 24 m/min for eight weeks. All mice were weighed once a week to monitor excessive increas...
