PURPOSE This study tested the hypothesis that one of the ways sports massage aids muscle recovery from exercise is by increasing muscle blood flow to improve "lactic acid" removal. METHODS Twelve subjects performed 2 min of strenuous isometric handgrip (IHG) exercise at 40% maximum voluntary contraction to elevate forearm muscle lactic acid. Forearm blood flow (FBF; Doppler and Echo ultrasoun...

Postural syncope may be noticed in otherwise normal persons with defective postural reflexes. Vasoconstrictor reserve--the extent to which total peripheral resistance can be increased from baseline condition is an important determinant of orthostatic tolerance. Women showed low autonomic support of blood pressure. The case of neurally mediated syncope is known to be greater in females in compar...

Measurement by systolic time intervals (STI) of cardiac responses requires extremely careful recording during actual stress test performance. Previous work indicated no significant changes in the pulse transmission time (PTT) during exercise and other challenges. Since external STI depend on the carotid pulse offset by the PTT as an aortic curve equivalent, stable PTT implies that timing of the...

The main goal of this work was to know the value of ventricular function in addition to perfusion Tc-99m sestamibi images in the assessment of coronary artery disease (CAD) when using dipyridamole (DIP) associated to isometric exercise. We analyzed 52 patients with suspected CAD; 40 of them had coronary lesions > or = 50% and 12 patients without CAD, conforming study and control groups, respect...

The analysis of explosive force, through rate of force development (RFD) and contractile impulse (CI), from handgrip strength data seems to be useful and promising information to study the aging of musculoskeletal system and health status. We aimed to test the hypothesis that, in elderly women, the handgrip explosive force could be better associated to the functional mobility than maximum handg...

The study was undertaken to assess the respiratory and sympathetic cardiovascular functions in obese and non obese school children of 12-16 years age group, randomly selected from two schools of Rajpura (Punjab), representing mixed socioeconomic group of Punjabi ethnicity and categorized as obese or controls as per standard criteria for Body Mass Index (BMI). Dynamic lung function tests and pre...

The aim of the present study was to verify acute effect remote and local IPC application before isometric strength, lumbar lower limbs manual grip, upper trunk muscle endurance tests in recreationally trained individuals. volunteers were 22 men (age: 26.2 ± 6.9 years, weight: 83.4 11.6 kg, height: 175.4 5.8 cm, BMI: 27.1 3.5 kg.m-2) (4.6 3.3 years) resistance exercise (RE) that performed three ...

1. Twenty-seven young subjects used their right hand to perform sustained, isometric contractions at 40% of maximum for 2 min while lying supine. 2. During the last 30 s of exercise, mean arterial blood pressure increased by 38 +/- 4 mmHg (mean +/- S.E.M.) and heart rate by 27 +/- 2 beats/min. 3. Nineteen of the subjects respired eucapnically during exercise, increasing ventilation by 4.1 +/- 0...

Although episodic changes in shear stress have been proposed as the mechanism responsible for the effects of exercise training on the vasculature, this hypothesis has not been directly addressed in humans. We examined brachial artery flow-mediated dilation, an index of NO-mediated endothelial function, in healthy men in response to an acute bout of handgrip exercise and across an 8-week period ...
