This means that two different people could make vastly different gains with identical time and energy investment. But as you can see below, the group that did bench press and lat pull-down first, improved those exercises the most. Strength is highly specific to the exercise, contraction type (eccentric vs. concentric), intensity, rep range, movement speed, range of motion, etc. Our body prefers to maintain homeostasis, so we’ve got to create some sort of stress that leads to an adaptation (Schoenfeld, 2013). Could you tell us about your fitness and nutrition interests? Learn more in our 2020 article about training to failure. However, the heavy loads used in this method of training indicate that it may be appropriate for preseason strength enhancement training microcycles, and that it should be restricted to athletes with sufficient resistance training backgrounds.” - Clark et al., 2011. Some volume-matched studies suggest that training a muscle group more (i.e. Though some individual lifts recovered faster in some individuals: Figure by Korak et al., 2015: Some lifts recover faster than others. Limitations: Does failure research apply to you? The metabolic basis for a change in muscle mass is an increase in net muscle protein balance (termed NBAL). Epub 2015 Jul 19. The 48+ hour recovery recommendation is supported by others as well (McLester et al., 2003; Jones et al., 2006). There is no cookie-cutter program: specificity and individual differences, How to implement this knowledge into your programming. Am J Physiol Endocrinol Metab. Table 1 from Pinto 2012 (edited for clarity). (...) strength coaches should consider individual differences and the type of workout being performed when prescribing the rest interval between sets.”. Volume-matched means that two groups use the same weekly training volume, even if they train a muscle group with different frequencies per week. that you choose to use. However, only the deep squat increased muscle mass in the legs and front thigh muscle size. The effects of protein supplements on muscle mass, strength, and aerobic and anaerobic power in healthy adults: a systematic review. If you can’t, just do your best. NIH Elliot TA, Cree MG, Sanford AP, Wolfe RR, Tipton KD. Which concluded with: “The present study also shows that long-term training adaptations in muscle strength and mass did not differ between the 2 hypertrophic strength-training protocols examined in the group of young men with a background in strength training.” - Ahtiainen et al. As you get further into your workout, it’s possible that you induce more central fatigue even if you switch muscle groups. Prescribing the appropriate rest interval does not ensure a desired outcome if other components such as intensity and volume are not prescribed appropriately. It appears from the literature there may be a discrepancy in hypertrophy for trained vs untrained. Isolation exercise has its uses in rehab, injury prevention, muscle imbalance correction, recovery management, programming, and bodybuilding (Tovin, 2006; Korak et al., 2015; Kolber et al., 2010; Gentil et al., 2016; Kompf and Arandjelović, 2016). The guidelines in the table are not a program, they’re more like building blocks you can use to make a program. A low training frequency strongly limits the amount of volume you can do (Serra et al., 2015), unless you spend several hours in the gym per session. Some might argue that the research presented above actually didn’t support higher-frequency training because results weren’t statistically significant (when comparing gains between groups). Debates are raging about what’s ideal for hypertrophy and strength. This makes the studies underpowered. Though, we should note that DOMS only lasted 48 hours when doing the compound exercise. There isn't much evidence that isolation exercise is required to maximize gains. The magnitude of the response may be influenced by factors other than just the amount of a nutrient ingested. Here are our thoughts on the meta-analysis by Schoenfeld et al., 2016: "Although increasing the training frequency may provide greater muscle growth, it may be difficult to increase the training frequency beyond a certain point. one group would do more volume, in addition to going to failure (or not going to failure)). It might be more practical to divide the sessions into 3 or 4 days per week. Strength is specific to the ROM you are using, but you can gain strength 20-30 degrees outside of the ROM you train with. Testosterone is a potent anabolic stimulus primarily through improvement in re-utilization of amino acids from MPB. In other words, very few studies were practical or realistic (“ecological validity”). Both groups trained to failure and significantly increased muscle CSA (9.3% for short rests, 4.7% for long rests) only having differences in volume for the BB curl which could explain the hypertrophy differences since the bicep was used to measure CSA. COVID-19 is an emerging, rapidly evolving situation. This fatigue could make you less confident in performing a lift later in the workout - so you lift less overall (Simão et al., 2012). Timing of ingestion, co-ingestion of nutrients and the type of protein may all influence protein accretion. This is something we need to account for when designing training programs, and it’s very easy to misinterpret study results as something that has to apply to everyone. You can make your own program (not advisable for beginners), you can choose a program that adheres to these principles, or you can modify a program you’re already on. A question that most of us would ask is, why would we not want to use a full range of motion? Results from acute metabolic studies provide useful information for estimation of the efficacy of anabolic agents. An example of an exercise that has longer total ROM for your pectoral is the dumbbell bench press. The most important exercise(s) should be done first in the session if you want to maximize the amount of reps you can do. 2004 Jun;4(2):165-74. Try to get a couple of working sets in, and hit the major muscle groups at least once per week. For example, you might be a high-responder to low volume high intensity training, but a low-responder to high volume low intensity training. If we look at all the evidence as a whole with all of its limitations, we can conclude that higher frequency training (i.e. Hepatocyte growth factor (HGF) is a key regulator of satellite cell activity. It should be said that substantial gains can be made with low frequency training, and the differences when volume is matched, are not huge. The table encompasses as many failure studies we could find, but we might have missed some studies. Note: Most of the research listed above didn’t reach statistical significance when looking at outcome differences between groups. Almost all participants were 23 year old untrained university males. Spreuwenberg et al. At what intensity? Though their strength loss could simply be a result of them overreaching.
