Mr. Paul Englert in particular, please let us (or maybe it's just me?) know what GVT is.

Baye" <drewbaye@gdi.net> >Subject: Re: SuperSlow vs. Explosive training >Wrong. Moving slower does increase the amount of force required to raise >the weight, because the slower you move, the less force momentum is >producing in the direction of movement, and the more force the muscle is >required to produce. This seems to be a confusing thing. If we think of a positive rep that begins from zero velocity and ends in zero velocity then the AVERAGE force output on the bar is independent on the rep speed, being the weight of the bar. If the rep speed is greater then the force requirement at the final part of the rep is indeed smaller. On the other hand the force output at the initial part of the rep is greater because of greater average acceleration at that stage. Let's say a person is lifting a 100 lb barbell with SS speed. His force output may vary between 98 lbs and 102 lbs. If he instead lifts the bar in 2 sec then his force output may vary between 90 lbs and 110 lbs but the average force output is 100 lbs in both cases. The speed itself doesn't determine the force output but the CHANGE of speed or acceleration (deceleration). Thus, if a person is lifting the bar with CONSTANT velocity, be it 0.1 m/s or 1.0 m/s, the force output is the same, in this case 100 lbs. Put in another way, the more momentum a bar has at a certain point the less force is required to lift the bar from that point on. But the momentum doesn't come out of nothing, it has to be created. And at the stage where you are generating that momentum you have to work harder i.e. use more force. The end result is that the amount of momentum you create at the initial part of a rep you will use up during the final part of the rep because momentum at the start and at the end of the rep is zero. Thus there must be at least two stages in a rep: 1) the stage where you accelerate the bar or generate the momentum and 2) the stage where you decelerate the bar or use the momentum you "earned". Then there may be a third stage where the bar is moving at constant velocity and where you don't either generate or use momentum. IMO, the significance of momentum is often exaggerated, it's said that the momentum will carry you through the rep. Let's suppose that the peak velocity during a rep is 0.5 m/s. Guess how much higher would the momentum at that point carry the weight. Answer: ONE HALF OF AN INCH! So much for momentum taking care of the rep of reasonable speed. >As for SuperSlow requiring a lower percentage of one's one rep maximum, you >forget to consider that one's one rep maximum is speed dependent. Of course the maximum weight one can lift in a movement is velocity-dependent but I've thought that when we speak of 1RM we mean the weight one can lift without any speed restrictions. Thus a 1RM is unequivocal. >Also consider that whatever percentage of one's MVC one uses is, to a >degree, irrelevant.

I have thought that tendons are created to enable ballistic movements. One of their properties is to store and release energy. I admit that using connective tissues as springs adds to the risk of getting hurt but I think that a happy medium can be found in this matter. If the muscles are properly warmed I don't see any point in totally avoiding elasticity in a movement. Erkki Turunen

This is not correct, it takes more force to produce the higher velocity. But in the example which Mr. Kreiger presented, the difference is less than 1%. And sorry, but as a physicist I take exception to something else here - momentum does not produce force, it is a result of force. > As for SuperSlow requiring a lower percentage of one's one rep > maximum, you forget to consider that one's one rep maximum is speed > dependent.

But if you are doing a 10 second one rep max, which you claim will be be with a lower weight than for a 2 second one rep max, then how can you possibly be contracting as hard as you possibly can? For you *could* contract harder and complete the rep in less time. Also, aren't you saying that very fast reps with light weights can use every motor unit available? The force requirements are higher to move the weight faster; if the forces weren't higher, then there would be no safety advantage in going slower. The faster the reps, the higher the force requirements, the higher the forces that could cause injury. The slower the reps, the lower the force requirements, the lower the forces that could cause injury.

The change in movement speed from a 2 to 10 second concentric drops how much weight you can get through the sticking point vastly. I've seen various numbers in the SS literature, anywhere from 30-40% drop in how much weight you can put on the bar. Lyle McDonald, CSCS Do NOT send me unsolicited binary files.

I now agree with Lyle >that a slow 1 rep max recruits 100% of muscle fibers. And, as Zatsiorsky explicity says (pg. 78) "In large proximal muscles... the recruitment of additional Motor Units appears to be the main mechanism for incrasing force development up to 80% of Fmm (my note: this represents maximum force capacity) and even higher. In the force range between 80% and 100%, force is increased almost exclusively by intensification of the firing rate (my note: this is rate coding, the number of signals sent to the muscle per second, measured in Hz)." >Also, the synchronization of motor unit firing is important. Highly developed >power athletes fire their MUs in synchronicity to develop even great forces. >Most of us do not do this. What he actually said was (pg 78) "...there is some evidence that, in elite power and strength athletes, MU's are activated synchronously during maximal voluntary efforts." >While he does not explicitly state this, Zatsriorsky seems to imply that only >through explosive training can all three of these factors exist. Where? I read through this particular section (have it in my lap right now) and he never states that explosive training is the key. He says 'maximal voluntary efforts'. Would you agree that a 2RM done slowly against maximal loads is a max voluntary effort? If you look at his suggestions for training methods, he offers maximal load training (1-3RM) and dynamic training (explosive training) as ways to improve inter/intramuscular coordination and rate coding. Nowhere does he say or imply that movement speed must be fast. >Kraemer believes that slow training does not increase one's ability to >generate force rapidly. Maximal force development in sports is often less >important than high speed maximal force development. Superslow training can >make one stronger, but this strength can only occur at very low velocities. You need to define your terms here. The Isokinetic speed studies I've seen generally compare velocities on the order of 100 and 300 degrees/second. And they find that there is specificty of training as would be expected. Slow speed isokinetic training tends ot improve performance at that speed and vice versa. But most sporting events occur in the range of several thousand degrees/second. How much difference in carryover is there really going to be between 100/300 deg/sec and 7000 deg/second. We're talking an order of magnitude here. >As many have already pointed out in this forum, you can move more weight when >you slow down the rep. But what athlete has the time to generate this type of >maximum strength? It is simply not practical. But now you're talking about something entirely differet: Rate of Force Development (RFD) which I already adressed in my post in this digest.

Compensatory acceleration will do this, as >will Olympic lifting. Super slow will only do it in the last couple of reps. You might wnat to look at some of Greg Wilson's work on bench pressing and force time curves. he showed quite well that even a 1.5 second bench press movement (81% of 1RM) has over 1/2 of hte movement as a decceleration. The physical fact of a necessity for ending velocity of zero (Vf = 0) in most weight training movement (Olympic lifts are an exception as is work on the Plyometric Power System and others) means that there will be a significant decceleration phase. The implications of which being that the faster you start out of the bottom, the sooner and the harder you have to slow down. So while you will show a higher peak force this way, you will spend a considerable amount of time (over half of the movement) applying a force which is less than what's on the bar. I agree that slower movements start to approximate an isometric but that means that the average applied force will be much closer to what's on the bar (since peak accelerations will be minimized) and you will load the full ROM much more evenly. With CAT you only load the initial part of the movement unless you have some very non-traditional training methods (like Louie Simmon's chains and a few others). So if you want to develop maximal strength across the fullest ROM, slower training makes sense. If you want to improve the start of a movement (coming out of the hole in a squat) use CAT. But at some point, individuals using CAT will have to train the endrange movement since it will be underloaded with a CAT style rep. This isn't a question of which is right, it's a question of which is appropriate for a given situation. Sadly the distinction of what type of program is appropriate for a given athlete in a given situation with a given goal is lost on those who want training to be a 'one size fits all affair.'

Training slower is safer. You pick the one you want to follow. Can we end this discussion now? >> No we can't... I am going to offer one (and ONLY one) more piece... I know a strength coach who doesn't have his football players do plyometrics. He understands that they can be beneficial, but he doesn't include them in his program. He does include the Olympic lifts (high pulls and cleans). With this training, the vertical jumps of his players went up -- even without practicing the skill of jumping. I include plyometrics in my programs and have witnessed the same type of results. Furthermore, the athletes I trained became faster in a 5 yard sprint (timed with an electronic timing devise), again without practicing the skill of a 5 yard sprint. I've always made it a point to question head coaches of the sports I was training if the training was effective and if he or she could see differences on the court or field. Always a yes response. Injuries during this type of training are so scarce it's not worth mentioning. I've seen close to 1500 athletes train and can count the injuries on one hand (all which are due to freak accidents). Research says explosive training and plyometrics work, personal experience from myself and other strength coaches says it works. The only ones who say it doesn't work are those who don't use it (and chances are, don't have a clue as to how to use it). Fred Hatfield II

It is simply not practical. I doubt anyone has said you can move more weight when you slow down the rep. People have said that lifting more weight will slow down the rep *automatically* because of the extra force. For instance if you do your 1RM, this rep will probably be a lot slower than if you were doing a rep at 85% of 1RM (unless you are trying to do the latter superslow). And what the heck do you mean by saying that superslow training only increase strength at low velocities? Are you saying that if I do a set of curls at 65 lbs superslow, that I wouldn't be able to do 75 lbs at a normal speed? That is a pile of B.S. Strength increase is strength increase. Eric B

Date: Wed, 29 Apr 1998 11:10:18 -0700 (PDT) From: SAILOR@webtv.net (Ken Roberts) Subject: Re: HIT Digest #132; Thoughts and questions r.e. slow/fast etc. #132 was the best digest yet! It actually looks as though you have developed the forum you wanted, Rob. Congratulations. I've been following the fast-vs-slow discssion with increasing interest, especially as I ave come to understand the difference between te ideas of simple recruitment and fatigue. And so the following thoughts/questions for those of you more knowledgeable than I. Certainly a slower movement will recruit 100% of the muscle fibres through the movement. But wont a more "explosive" movement actually increase the amount of weight one must move at the beginning of the movement due to the laws of innertia? It seems to me that if I curl 100# slowly then I am moving 100#,yet, the weight of that bar should increase exponentially the faster I move it, albeit only through the inital phase of the movemnt. However, wouldn't that be enough to recruit 100% of the fibres and secondarily, fatigue the IIB fibres more effectively? Assuming that being the case, wouldn't it be more effective to combine fast with slow? I.E. fatigue the fast twitch fibres first with a heavier weight moved quickly then a lighter weight for higher reps moved more slowly? That way one would be assured of maixmal inroad? Which leads me to ask, why the 20% rule? Wouldn't one be able to make better gains in muscle size with greater inroad (given adequate nutrition and recovery)? Now, does anyone know if there is an optimal exercise level for calorie expenditure? What I'm driving at is this. If I wan't to burn cal's. optimally I want to exercise a certain ammount. One utilizes cal's. by increasing work. I can do this by exercising over time or I can increase the intensity of the exercise and threby increase the ammount of work (cal. expenditure). So, if my one rep max is 100# in an exercise am I doing the same amount of work by lifting 100# once or 80# 10 times? I think the answer is obviously the latter, however, is there a more efficient way to use more cal's. over time (please asume all other factors, time per rep. etc. are the same)? Which kinda brings me full circle. If TUT remains the same, and I can lift heavier weights "explosively", might I not be better off using a more "explosive" movement for the purpose of energy use?
