  • intensity
  • When you're working out at a low intensity, your slow-twitch muscle fibers are recruited first. (musclemagfitness.com)
  • Many popular high-intensity exercise programs feature jumps, hops or skips to increase power output in lower-body muscles, but omit exercises for developing upper-body power. (acefitness.org)
  • Do a complete dynamic warm-up to properly prepare your muscles before beginning the high-intensity exercises of the working sets. (acefitness.org)
  • A high-intensity heavy load applies a mechanical stress to muscle, while performing a high number of repetitions creates a significant metabolic stress. (acefitness.org)
  • This is the muscle fiber type you would use if you were to run a marathon or any other extended duration, medium-to-low intensity activity. (archive.org)
  • High intensity training over a prolonged period of time improves the ability of a neuro muscular system to recruit a greater number of motor units (volley firing), and thus creates a greater number of muscle fibers to contract. (bodybuildingpro.com)
  • enzymes
  • Muscle mass is mainly controlled by the ubiquitin-proteasome system (UPS), involving hundreds of ubiquitinating enzymes (E2s and E3s) that target their dedicated substrates for subsequent degradation. (mdpi.com)
  • muscular
  • This is to enable sufficient oxygen to get to the muscle tissues so that they can carry on the extended duration of muscular work they are intended to do. (archive.org)
  • high
  • While strength is the physical ability to generate a high amount of muscle force, power is the ability to generate a high amount of force in a short period of time. (acefitness.org)
  • The high eccentric forces required to slow the bar down as it descends can help improve upper-body strength and power. (acefitness.org)
  • They are also relatively slow to contract, therefore you cannot expect a great deal of force generation from these muscles, and thus, will not be intended for exercises requiring a high degree of power. (archive.org)
  • higher
  • To begin, as a general rule, the higher number of reps you do, the more you will work your slow-twitch muscle fibers. (myprotein.com)
  • Higher rep ranges, mind-muscle connection, isolation training, and other intensification methods increase gains more than lifting to increase your one-rep max. (t-nation.com)
  • lactate
  • The second ventilatory threshold (VT2) occurs when the rate of accumulation of lactate in the muscles begins to exceed the ability of the circulatory system to recycle it. (acefitness.org)
  • exercises
  • If you exercise for the purpose of improving your performance in sports such as tennis, softball, baseball, volleyball or Ultimate Frisbee, or if you want to improve your ability to perform daily tasks such as carrying a bag, caring for young children or gardening, it is important to perform exercises to improve the strength and power of the muscles of the upper back, shoulders, arms and hips. (acefitness.org)
  • Here are six effective exercises to incorporate into your clients' programs to help them activate and strengthen this powerful lower-body muscle. (acefitness.org)
  • exercise
  • First, pick the muscle group that you want to test and an exercise that will use those muscles. (musclemagfitness.com)
  • It is important to include some power training in an exercise program to help improve the speed at which your muscles generate force. (acefitness.org)
  • According to the principle of specificity, muscles grow and adapt in response to the applied forces used during exercise. (acefitness.org)
  • If the goal of an exercise program is to create large, well-defined muscles, machine training can be an extremely functional way to achieve that outcome. (acefitness.org)
  • body
  • You will be putting your body through new extremes when you increase the weight you are lifting, and will therefore, need to place the same importance on rest so that your muscles can heal and grow. (myprotein.com)
  • But if they dropped down to reasonable body fat levels they'd likely lose a lot of muscle in the process. (t-nation.com)
  • Their muscles look visibly longer, and they usually have little body fat. (breakingmuscle.com)
  • larger
  • There are multiple ways in which muscles can grow larger without significantly affecting maximal strength. (t-nation.com)
  • reps
  • For example, if you were to perform an all out set of 3 reps for bench press, you would predominately be using these type A muscle fibers. (archive.org)
  • force
  • Along with neurological adaptations, adaptations involving increased stiffness in the tissues that connect from bone to bone (including tendons, extracellular matrix, etc.) can lead to increased force transmission from muscle to bone, and play a significant role in increased strength gains. (t-nation.com)
  • Specifically, increased pennation angles appear to have a negative correlation with muscle strength - as pennation angle increases, a muscle's force-generating capacity decreases. (t-nation.com)
  • gains
  • Breast cancer treatments can cause accelerated gains in fat mass and losses in muscle and bone mineral density (BMD). (acefitness.org)
  • Of these adaptations, basic coordination between the muscles is the single greatest contributor to non-hypertrophy related strength gains. (t-nation.com)
  • time
  • A long-time performance enhancer for strength-training enthusiasts, whey protein is best known for its ability to help increase muscle mass. (acefitness.org)
