Please correct me if Im wrong here, but Im fairly certain the maximum force of fast twitch and sow twitch fibers are fairly similar. Theres just not clear evidence that training in specific ways will lead to preferential growth of Type 1 or Type 2 muscle fibers. You are an expert in the field, and just conversing back and forth was so enlightening. Overuse stress Type 2X are the most powerful and the least endurant, while Type 2A fibers are effectively a midpoint between Type 1 and Type 2X fibers more powerful than Type 1 but less than Type 2X, and more endurant than Type 2X but less than Type 1. The one repetition maximum tests (1-RM) is a measure of the maximal weight a subject can lift with one repetition. Evenif there was an easy way to know a muscles fiber type breakdown, and evenif there was clear evidence that low intensity, high rep training caused more Type 1 muscle fiber growth (and vice versa), I dont think that would change my generalrecommendation to train with a variety of rep ranges, placing more focus on the rep/intensity zone most in line with your goals: For strength: Do mostly heavy, low rep training with some lighter moderate-to-high-rep training mixed in. 5th June 2016 | 5 min read. Whether you can get a shift from Type 1 to Type 2 with training (or vice versa) is a little more contentious.

Great information that is going to help me become a more well rounded health care professional! If tanx2\tan \frac{x}{2}tan2x=tan A tanh B, prove that: tanx=sin2Asinh2B1+cos2Acosh2B\tan x=\frac{\sin 2 A \sinh 2 B}{1+\cos 2 A \cosh 2 B}tanx=1+cos2Acosh2Bsin2Asinh2B. Resistance training has been shown to down regulate the gene expression of type IIx fibers, converting type IIx fibers to type IIa fibers. Its just that the slow twitch take longer to ramp up to that force, whereas the fast twitch can provide that force pretty much immediately. Results vary study to study, but Type 2 muscle fiberstend to grow about 25-75% more in response to training than Type 1 muscle fibers do. Power training A proper 1RM warmup includes explosive movements in an unloaded fashion to stimulate the CNS, getting the fast-twitch (type II) muscle fibers lit up and ready to rock. First off, it fills a much needed gap in providing a sound education on the merits of HIT. Dohoney, J., Chromiak, D., Lemire, B.R., Kovacs, A., & Kovacs, C. (2002). Fast twitch fibers can be further categorized into Type IIa and Type IIb fibers. (2006) Strength training: development and evaluation of methodology. The researchers had the participants warm-up, and then gradually work up to a 1RM squat. It would be bad enough if this test explained a bit less than 1/4 of the variability (as in the prior study), but it seems that this test actually explains closer to 0% of the variation.

To figure out your 1RM without actually attempting it, estimate it by doing a set of 510 reps with lower weight. Predicting maximal strength in trained postmenopausal women. There are three problems with this approach: Im only aware of two studies that have compared fiber type breakdown with maximum reps at a set percentage of 1rm. Type I and type II fibers are both capable of hypertrophy, although the size increase in pure type I fibers is considerably less compared to type II fibers. The business of being a successful personal trainer or gym does not just rely on your understanding of HIT and exercise of equal importance is how you work and interact with clients, how you adapt the protocol to the individual and special populations. Maybe one person gets a 5th rep easily andbarely misses a 6th with 85% of their 1rm, and another person has the grind of his/her life to eek out the 5th rep theres obviously a qualitative difference in fatigability, but a rep max test isnt going to pick up on it. Furthermore, it can also be useful to calculate relative strength (kg lifted per kg of body weight) when comparing the strength abilities between multiple athletes/individuals. Specifically, the types of fibers that make To find the predominant fiber type in a particular muscle in your body, you can try the following test. Even if there was a tiny negative change, this would be outgunned by aspects such as improved neural drive and coordination when practicing 1RM. a 1RM test) appears counterproductive, the studies appear to have produced valid and reliable results. Job problems Indeed very few trainees in the wider population will be prepared to tolerate a James Steele style 3-minute wall sit. Relative strength is how much weight an individual can lift per kilogram of body weight (kg lifted per kg of body weight). 2011 May;96(5):539-47.

This is a simple indirect test that is used to estimate the predominant muscle fiber type - slow twitch or fast twitch. Grgic and Schoenfeld however, also point out this is theoretical as there is currently a lack of evidence to support longer TULs for improved type I hypertrophy. Type 2 fibers tend to be more responsive to strength training. Though a rest period of 1-2 minutes between a maximal-effort anaerobic exercise (i.e. The graph below shows an individuals force production during a maximal voluntary contraction sustained for 3 minutes. Effects of high resistance training in coronary artery disease. If the environment is not consistent, the reliability of repeated tests at later dates can be substantially hindered and result in worthless data. If you get 7-9 with 80%, or 4-6 with 85%, you have an even mix of Type 1 and Type 2 fibers in the muscles targeted by the exercise youre testing. Before you could train a muscle a specific waydue to its fiber type breakdown, youd need to actually know its predominant fiber type (or at least have a good idea); unfortunately, it doesnt seem like this popular test works very well.

The 1RM test is often considered as the gold standard for assessing the strength capacity of individuals in non-laboratory environments. Whilst some studies have used only 1-2 minute rest periods between 1RM attempts (3, 13, 14, 1, 7), others have used 3-5 minutes (8, 9). Training According to Muscle Fiber Type If a client's main goal is to improve muscular endurance you must design a program that will target type I muscle fibers. I have taken other certification programs. Perhaps by finishing with one or two higher rep sets or by complementing with other exercises. Positively, this paper suggests that a wide range of loads (between 40-80% of 1RM), and therefore TULs (50-120 seconds), in sets taken to MMF, are effective at stimulating hypertrophy and are effective to a similar degree. There was a small, inverse correlation (r=-0.38) between the number of reps participants could do and their percentage of fast-twitch fibers. While working up to your max effort, rest intervals need to be longer to give your CNS adequate recovery time. (A 2/2 cadence was used and sets were taken to MMF).

Think back now to the sustained MVC that appears to significantly fatigue all type II motor units within 90-180 seconds (individual dependent). It starts with Type 1 muscle fibers, activating more and more until it needs to call upon Type 2 muscle fibers, activatingmore and more until you eventually cant produce any more force (this is called Hennemans Size Principle or the Principle of Orderly Recruitment). Because you expand all your effort on a 1RM, and are unable to lift a heavy weight for five reps. Conversely, if you can handle high reps, you must be slow twitch dominant. Comfort, P, Stewart, A, Bloom, L, and Clarkson, B. Whether this happens with a synchronous recruitment of all motor units from the outset (80% 1RM) or a sequential recruitment that builds over the set (40% 1RM) may not matter.
