Aerobic and Cardio Fitness
Your aerobic capacity and your cardio conditioning are related because the heart and lungs work together to draw oxygen into the body, to send it out through the bloodstream, and to reprocess it. The cardiovascular system refers to the organs involved in this whole process, and your endurance is a function of your cardiovascular health. The entire heart-lung system is referred to as the cardiopulmonary system. To test the efficiency of your heart and lungs, the trainer will measure your heart rate. Heart rate is fitness-speak for pulse. In other words, the number of times your heart beats each minute. Your resting heart rate is your pulse before you even get out of bed in the morning.
Another Mechanism Contributing To Heart Failure Revealed By Genetically-Modified Mice
Scientists at the Robarts Research Institute at The University of Western Ontario, working in collaboration with researchers in Brazil, have used a unique genetically-modified mouse line to reveal a previously unidentified mechanism contributing to heart failure. The study, led by Marco Prado, Robert Gros and Vania Prado of London, Canada and Silvia Guatimosim of Brazil, shows how the decreased release of the neurotransmitter acetylcholine, a chemical messenger which slows cardiac activity, contributes to heart failure. The study is published online in Molecular and Cellular Biology at http://mcb.asm.org/cgi/content/abstract/MCB.00996-09v1 Heart failure affects close to a half million Canadians, often as a result of conditions including coronary disease, high blood pressure, diabetes and high alcohol or drug consumption.
More and More Women Are Turning to Kickboxing For Physical Fitness
Kickboxing is not a 'males only' sport. Women too love kickboxing as they learn to defend themselves in a fun filled way that does wonders to their physical fitness levels. It is a distant remove from the monotonous treadmill running and lifting of weights that keep off women from hitting the gym. Kickboxing is not only engaging, it kicks starts reflexes instantly like no other physical fitness exercise does and keeps energy levels high all through. Bouts carry enough motivation for women to improve their fitness standards and trim the flab. Usually at the kickboxing gyms the staff sees through the paces and ensures that the women don't get hurt.
New TAU Study Proves Smoking Cessation Significantly Increases Cardiac Health Later In Life
Smoking affects your cardiac health both before and after a major event like a heart attack. But how much? And does cutting back instead of quitting have a positive effect as well? There are definitive answers in a new study from Tel Aviv University, the largest and most comprehensive of its kind. The research found that quitting smoking after a heart attack has about the same positive effect as other major interventions such as lipid-lowering agents like statins or more invasive procedures. Study results were reported in the Journal of the American College of Cardiology. "It's really the most broad and eye-opening study of its kind, " says Dr.
UT-Battelle Licenses Tissue Regeneration Technologies To NellOne Therapeutics, Inc.
In a major step toward commercialization of a promising therapeutic treatment, Oak Ridge National Laboratory contractor UT-Battelle has exclusively licensed patents on inventions based on the Nell-1 gene to NellOne Therapeutics, Inc. (NellOne), a company spun out of the Department of Energy laboratory. The protein therapy treatment under development takes advantage of the Nell-1 gene's cell-signaling pathway that controls tissue growth and maturation in mammalian organs. The foundation for this therapy is research performed by Cymbeline Culiat, who as an ORNL systems genetics researcher identified the role that the Nell-1 pathway plays in tissue growth and maturation.
