Exercise training can improve strength and lead to adaptations in the skeletal muscle and nervous systems. Skeletal muscles can develop into two types: fast and slow, depending on the expression pattern of myosin heavy chain (MHC) isoforms. Previous studies reported that exercise altered the distribution of muscle fiber types. It is not currently known what changes in the expression of caveolin...

To investigate the effects of strenuous forced exercise on the course and complications of a bacterial infection and on myocardial responses and performance capacity, rats with tularemia (characterized by pyogranulomatous hepatic and splenic lesions) were exercised by swimming on days 0-6 of infection. Levels of glutamic oxaloacetic and pyruvic transaminases in plasma, densities of pyogranuloma...

   Cromolyn sodium, a mast cell stabilizing agent, provides an immediate protective effect against the exercise-induced bronchoconstriction while being used before the exercise. However, cromolyn is ineffective in reversing asthmatic bronchospasm; it is used as a maintenance therapy and has a prophylactic role in chronic asthma.    The purpose of this study was to determine the extent of change...

[PURPOSE] THE AIM OF THIS STUDY WAS TO REVEAL THE EFFECT OF EXPIRATORY MUSCLE FATIGUE (EMF) ON RESPIRATORY RESPONSE UNDER TWO DIFFERENT EXERCISE CONDITIONS: exercise (EX) with EMF (EMF-EX) and control EX without EMF (CON-EX). [Methods] Nine healthy adult men performed cycle exercise with a ramp load, and a spirometer was used to measure forced vital capacity (FVC), forced expiratory volume in o...

Effects of forced sleep-wake schedules with and without physical exercise were examined on the human circadian pacemaker under dim light conditions. Subjects spent 15 days in an isolation facility separately without knowing the time of day and followed a forced sleep-wake schedule of a 23 h 40-min period for 12 cycles, and physical exercise was imposed twice per waking period for 2 h each with ...

[Purpose] This study was conducted to investigate the effects of forced breathing exercise on the trunk functions of chronic low back pain patients. [Subjects and Methods] Twenty-four patients with chronic low back pain were randomly divided into groups of respiratory effort and trunk stabilization exercises. The exercises were performed for 45 minutes, 3 times per week for 6 weeks. Spinal stab...
