Just like similar molecules, 1-Androsterone has a half life. When taken in pill form, you rely on the body to break the pill down then the molecule, resulting in wasted time and causing excess stress on the liver and other organs (1-Androsterone Liquid™ avoids the first pass through the liver entirely). This often results in only 15% of the molecule being delivered in the first hour. So for you to achieve sufficient blood levels of the molecule in pill form you must take 100 mg (15 mg the first hour) 2 times a day. However 1-Androsterone Liquid™ is fully dissolved in the Liposomal liquid solution, the full dose of 20 mg can be delivered in 1 hour (as compared to 15 mg with pills), reaching blood plasma levels sooner. The advantage over capsules is colossal!
Concentric muscle contractions occur when a muscle shortens during contraction, as in the upward motion when performing a biceps curl. An eccentric contraction occurs when a muscle lengthens with contraction, as in the "negative" or lowering motion of a biceps curl. An example of an isometric (muscle contracts while maintaining constant length) contraction would be pushing against an immovable object. An example of an isokinetic (muscle has constant speed of contraction) occurs with specialized equipment like Cybex machines. Plyometric contractions occur when a muscle rapidly lengthens just prior to contraction - like during repetitive box jumping.
Woo and Buckwalter describe the mechanisms, barriers, and molecular processes involved in ligament and tendon injury and repair.
Negative results are important, too . Don’t neglect the studies that don’t show anything. What do I mean? There is a bias towards positive results (., something happened or changed because of an intervention). Negative results are just as important because they still add to existing knowledge. Often people miss the data that doesn’t support the idea being put forward and authors choose to ignore that data, and instead put forward only that data that appeared to support their beliefs. If you read the research quoted deeper sometimes it contradicts the recommendations. Check to see that the information is complete, comprehensive, and verifiable through other resources.
