Shock Muscles Into Growth
Change Your Routine!
Hormones such as human growth hormone (GH) and testosterone have been shown to play a role in muscle hypertrophy and strength gains. One of the core training principles for muscle hypertrophy among weight trainers is short rest— less than 1 minute between sets. In 1988, anabolic hormone guru William Kraemer, Ph.D., performed a study that literally changed the world of weight training overnight.
Blood Flow Restriction During Exercise Does Not Damage Muscles
A literature review by Jeremy Loenneke from the University of Oklahoma and colleagues concluded that blood flow restriction training caused no prolonged decreases in muscle function, prolonged swelling or increased blood markers of muscle damage or inflammation.
Sprint Cycling Increases Growth Hormone and IGF-1
Israeli researchers from the Sackler School of Medicine in Tel Aviv found that growth hormone, IGF-1 and lactate increased during a single 30-second maximal sprint on a stationary bike (i.e., Wingate test).
Muscle Activation Similar During Squats and Sled Pushing
Meaghan Maddigan and colleagues from Memorial University of Newfoundland in Canada found that muscle activation patterns were similar during squats and sled pushing.
Muscle Versus Powerlifting Workouts for Size and Strength
Brad Schoenfeld from Lehman College in New York City and colleagues found that trained subjects performing muscle-building or powerlifting workouts gained muscle mass equally, but that the powerlifting workouts produced superior strength gains.
Longer Rest Intervals Better for Gaining Strength and Hypertrophy
A study led by Brad Schoenfeld from CUNY Lehman College in the Bronx, New York found that resting three minutes between sets produced greater changes in lean muscle and strength than resting one minute.
Ballistic Squats Increase Vertical Jump Height
Timothy Suchomel from East Stroudsburg University in Pennsylvania, and co-workers, measured vertical jump height in test subjects two minutes after performing a single maximum-rep squat, either ballistically or non-ballistically.
Markers of Muscle Damage Less During Second Workout
Brazilian scientists, in a study on strength-trained athletes, found that muscle soreness and markers of inflammation were less during a second workout designed to cause muscle damage.
