Tempo Training and SPL at Faster Tempos

Based on my coach’s suggestion, on the next workout I decided to swim at a higher tempo settings.
After warming up, I set my tempo trainer at 1.6 seconds, swam 4×25, then lowered my tempo by .1 seconds, swam another 4×25, until I got to 1.2 seconds tempo where I determined my comfort breakpoint usually is.
Here are my results:
1.6 seconds, SPL: 13, 12, 12, 12
1.5 seconds, SPL: 4×12
1.4 seconds, SPL: 4×13
1.3 seconds, SPL: 4×13
1.2 seconds, SPL: 13, 13, 13, 14
Once I started getting tired at 1.2 seconds, I drifted to 14 SPL and stopped, knowing I would probably get frustrated with trying to keep my SPL with rising fatigue.
At my next workout, I decided to go even faster. My coach tells me that sprinting tempo is around .8-.9 seconds. I wanted to see what that felt like and whether I could even keep up a decent form. Starting from 1.6 seconds tempo to give myself a bit of warmup, I did 2×25 at each tempo setting until I got .8 seconds.
Here are my results:
1.6 seconds, SPL: 13 12
1.4 seconds, SPL: 13 13
1.2 seconds, SPL: 14 14
1.1 seconds, SPL: 15 15
1.0 seconds, SPL: 16 16
0.9 seconds, SPL: 17 16
0.8 seconds, SPL: 17 17
The fast tempos are too fast for me at this point. My body coordination to stroke, body turn, and kick, as well as breathing at that tempo is a bit too difficult to maintain right now. I also found that I could not maintain my stroking force as well as when my tempo is slower. In order to maintain tempo, I have to reduce my force and just get used to cycling my arms at that speed.
Computation of speed to complete a 25y length is, using my coach’s formula:
1.2 seconds @ 14 SPL: 20.4 seconds
1.1 seconds @ 15 SPL: 19.8 seconds
1.0 seconds @ 16 SPL: 19 seconds
0.9 seconds @ 17 SPL: 18 seconds
0.8 seconds @ 17 SPL: 16 seconds
One of these workouts, I have to time myself to see how accurate these time computations really are.
Observations:
1. I think that I did not “spin” and that I was actually gliding a bit with each stroke. But it was harder to see this effect at the higher speed.
2. I need to find a way to maintain force at higher tempos. To maintain that force is very difficult for me now and also cycle fast.
3. My coach told me that when you cycle faster, you need to stroke shorter, lifting your arm out of the water sooner. Also, everything is happening faster so I have to get used to doing the whole swim movements faster and precisely. At the same time, I need to be as relaxed as when I was swimming with slower tempo. Tensing up just makes me slower and more tired.
4. Like with running, I am going to start neuromuscular training for swimming. I think I will add in a training session where I am just swimming at fast tempo, but not necessarily caring what my SPL is.

Tempo Practice Maintaining Strokes Per Length

Monday I swam, thinking a lot about what Coach Shinji and I worked on Saturday.
I warmed up and then instead of only practicing Strokes Per Length (SPL) I did SPL with the tempo trainer.
As one workout, I will practice SPL without caring about tempo. I just keep trying to maintain the lowest SPL for as many 25y lengths as possible, until I start to tire. This time I decided to do something slightly different. I wanted to see if I could maintain the same SPL but at a higher tempo. In doing so, I could practice efficiency but at higher speeds. I can start practicing what it takes to be efficient at higher tempos, and what I need to do in my stroke and body position to make it so.
I started at 2.0 seconds on my tempo trainer and did the first 25y length at 13 strokes then got to 12 strokes on the next three 25y lengths. I then went to 1.9 seconds and maintained 12 SPL for four 25y lengths. I then dropped to 1.8 seconds and so on, swimming four 25y at 12 SPL at every tempo setting. I finally found my limit at 1.5 seconds where I was feeling like I was gliding a little bit longer at my 12th stroke to the wall. At 1.4 seconds I lost 12 and did 13. I tried for the next three lengths to hit 12 and think on the last one I could have finally glided to the wall on 12, but took the extra stroke anyways.
It was very interesting to note exactly what I had to do to maintain 12 SPL especially at faster tempos. At 1.5 seconds, I really had to shoot the forward arm fast while stroking back with the other arm with more speed/force. But I also had to do this by being more relaxed and not tense, and also making sure my body streamline was more precise. Just more stroking force and forward arm speed was not enough. At 1.4 seconds tempo, it took me 3 lengths to get the right technique to barely make the 12, even as I took the 13th stroke to firm up hitting the wall.
I was also getting tired too so that didn’t help. In addition, as my tempo rose, it seemed my breathing technique got messier and I was not gliding as much when I took a breath.
I sent this to my coach for feedback and he told me that this is a good thing, which is to be able to control my speed at the same stroke count. He estimated my time to hit the wall on a 25y length at 2.0 seconds tempo to be about 30 seconds (12 SPL x 2.0 seconds tempo + 2.0 seconds tempo x 3 additional strokes my coach adds for the push off the wall and glide = 30 seconds). Using the same formula, at 1.5 seconds tempo it took me about 22.5 seconds. So between 30 seconds to 22.5 seconds I could control my speed and still maintain my SPL.
He also told me that my body position must be more precise as I increase my tempo, and that being tense will make me slower. He mentioned that as I practice the various tempos, I can eventually determine what part of my body I should loosen and tighten up to maintain SPL.
He then told me to practice the same process with 13 strokes, but now at a faster tempo range like 1.6 to 1.3 seconds. Then I repeat until I get to 15-16 SPL at a super fast 0.8 seconds. If I can master this tempo control and maintain efficiency, then I can employ a variety of speeds during races.
Cool stuff. I think over the next few weeks I will work a bit on seeing if I can maintain 12 SPL at higher tempos for some of my workout sessions. I will also try to figure out what it is my body needs to do to be more efficient at higher tempos. It will be critical in figuring out how to get faster in the water and not just be exponentially increasing my effort needlessly to get a tiny increase of speed.

Total Immersion’s Superman Glide

Total Immersion has this drill called the Superman Glide. You basically push off the bottom of the pool (not the side; that’s cheating!) and launch yourself forward into the “Superman” flying position.
The object is to practice good streamlining, relaxation and no tension. If you do it right, you will zip farther in the pool before you stop than if you have poor streamlining or have an extremely tightness in your body.
My Coach Shinji can glide 18y on a single push off. It’s pretty freakin’ amazing:

One exercise I did was to see how many Superman Glides it would take to get to the end of a 25y pool. At first, it took me about 4.5. Over the last few months, I experimented with a lot of tweaking of my body positioning and finally made it in 3 glides. Some things I found that worked:
1. Relaxing is much better than stiff or tight. I just exercise enough tension to hold my arms straight out in front of my head, and to extend my legs. But no more than that.
2. However, relaxing totally didn’t work either. It meant that my body was a bit too loose and resulted in a less streamlined profile than holding enough tension to extend my body more sleekly.
3. I discovered that narrowing my body profile by extending my arms forward of my head is better than just putting them out there in a “V”. my shoulders are actually extended forward with my arms so it reduces the width of my shoulders.
4. I straightened my back, which feels a bit like arching the back to remove the natural curve of the spine. This is also achieved by rotating the hips forward a bit. A flat back seems to make me go further.
5. My legs do not just hang back relaxed. There is too much drag if they are just hanging out straight. Instead, I make a conscious effort to keep them straight back and touch my feet gently together, which puts my legs in my slipstream.
6. On the push off from the bottom of the pool, I plant my feet firmly before pushing off. I also try to push forward, which is tough because the bottom of the pool is slippery. It is better to plant the feet on the non-tile portion of a lane. Tiles are much more slippery than the other non-tile surfaces of the pool bottom.
I push off as straight as possible. Any angle or upset in my direction will either push me into a lane line or cause me to rock, which increases drag.
I try to push off as hard as possible. This is very hard because my feet slip on the bottom, even if they are not on the tiles. A harder push means more forward momentum, but is hard to achieve because your feet don’t have a nice surface to grip onto.
7. As I glide and slow, there is a tendency for my legs to drop. I try to flex whatever muscles in my back I can to keep my legs as high as possible, and to extend the time before my legs drop. Letting your legs drop is OK as far as the exercise goes, but it does not let you achieve your maximum length glide.
I only let my legs drop when I come to a complete stop.
8. By the way, you should be rested and not out of breath from warming up, or doing laps before. Gliding a long time also means holding your breath a long time until your forward motion stops so you don’t want to stop the glide early just because you’re running out of air!
9. I am very sensitive to the water flowing around every inch of my body. As I develop my position, I try to sense where is water causing drag on my body and where it is not. If there is drag, I try to change something on the next glide to see if I can remove the drag. This is also helpful during regular swimming, which is to see if anything on your body is slowing you down.
One of these days, I hope to achieve an 18y ultimate Superman Glide!

TI Swimming with Coach Shinji 12-12-09

Another great session with Coach Shinji this last Saturday. It was a rainy, cold day but us swimmers don’t care; we’re wet anyways. It’s not so nice for coaches who have to stand in the rain though.
Everytime I work with him, I always get a few more tidbits of insight from him. Some notes:
1. Practice varying the entry point from very wide to very narrow. Find the place which is most comfortable and also generates the most speed. Open water swimming tends to have a wider entry point than in the pool. Narrow entry points allow for longer hand motion under the water as the hand shoots forward, generating more momentum.
2. Wetsuits don’t allow as much roll so you have to learn how to generate motion on a wider track.
3. Push down on the instep when snapping the kick.
4. If I increase tempo too fast, then I could spin, which is when my arms are just cycling but I stop after each stroke and there is no glide. I must learn how to increase the tempo but do not spin.
5. If my SPL jumps at a certain tempo then this is the point at which something is wrong or something has changed.
6. At each tempo, I should count stroke and look at how it changes as tempo changes.
During this session, Shinji and I started at 1.2 seconds tempo, and did 25y lengths counting strokes, with each length decreasing the tempo by .1 seconds. I did this all the way up to 2.0 seconds tempo, and my SPL ranged from 15 in the beginning to 12 at the end. Then I increased the tempo by .1 seconds for each 25y length, all the way down to 1.2 seconds. I discovered that at around 1.3 seconds, my SPL jumped to 15 and realized that at this point, I needed to concentrate on what had changed, and how to maintain SPL.
7. Slower tempo requires more relaxation and good balance. There is more gliding, so you need to glide with balance and not rock.
8. Eventually I need to get to .8-.9 seconds tempo, which is sprinting and used when you’re trying to break out of a pack of swimmers during a race.
9. I need to turn the elbow slightly inward which will prepare my hand for the catch. This is also done my turning the thumb in and down. If my elbow is turned the other way, then I will waste a bit of time getting my arm in position for the catch, which can deter me from achieving a higher tempo.
10. When skating, I need to end my hand on top of my thigh, or else my body will more easily over rotate.
11. When I swim, I am throwing water backward with my right hand and not my left. Need to examine this further. I should not be throwing water back.

Learning to Breathe and Sight with Shinji Takeuchi’s TI Swimming 11-13-09

It’s been almost a month since my last lesson with Shinji. My blog was busted until now but finally I can post my notes from my last swim session with him.
This session was focused on improving breathing, and also learning TI’s sighting method which was slightly different than what I was doing.
Previously I noticed that my speed would suffer when I took a breath. Every time I would breathe, I would take the breath and turn my head and look back downward in the water and notice that I had come to almost a complete halt. I needed to figure out how to breathe and still be gliding and not at a dead stop due to bad streamlining.
We went through some drills to improve breathing and not slowing down. The drills were very basic, which was to break down the movement and drill each part partially until the whole movement was perfected.
Generally, the head turns with the body and remains in neutral position with respect to the body position until the very last moment as the head is almost breaking the water, at which point the head turns slightly to take what they call a “sneaky breath”. The water is still sticking to the mouth at this point, and you have to exhale slightly to clear the water away from the mouth so that a breath can be taken. If you move the head too much, you create drag which slows you down.
Also, I’ve found that after reading the TI forums, that slowing down occurs when I do not completely shoot the lead arm forward and complete a strong stroke, and that when I breathe, sometimes I forget to complete the stroke sequence correctly.
These drills were:
1. Take 4 strokes with head down, then turn the body and head until you look at the raised arm (after the stroke and arm recovery, but holding it up in the air) but no taking the breath yet.
2. Take 4 strokes with head down, then turn the body and head until you are almost breaking the water, then turn the head slightly and exhale (to clear the sticking water), and take a breath. Then turn the head down and glide, leaving the recovering arm in the air after its stroke.
3. Do 2, but then recovering arm completes the next stroke after breath.
Since I breath on the right side primarily, I start with the left arm leading and do the 4 strokes, at which time the right arm is the last stroke and can breathe on the right.
For sighting, Shinji says to sight when I shoot the right arm forward. It needs to shoot a bit shallower, as I lift the head up to look above the water. Then drop the head down and complete the stroke.
Drills to practice:
1. Take 4 strokes, then when I shoot the right arm forward, look up to sight and glide.
2. Do 1, then take a stroke after looking up.
3. Do 2, but take a breath after a stroke to get the rhythm of sighting regularly and breathing.
4. If 1-3 too hard, try stroking a few and then shoot the right arm forward and left head to sight, and scull the arms to practice gliding a bit while looking.
I practiced this extensively in the oceans of Hawaii a few weeks back. It works pretty well but the timing is a bit funny for me in the beginning, but I think I got the hang of it.
Other notes:
1. To improve breathing, practice active balance drills. Practice glide and while kicking, rotate the body and practice the ease of doing so.
2. I was still kicking with a lot of splash, so practice silent kicking. Quick, smooth, minimal splash.
3. Same with stroking. No bubbles, enter the arm smoothly into the water, no splash. Focus on quiet entry and shoot forward.
4. On left arm forward skating, I tend to tilt my head to the left. I must keep it straight.
5. Overhead arm recovery is not choppy, but smooth.
6. Another arm recovery drill, while underwater, is to lift the arm circularly up from the bottom.
7. We talked about improvements to practicing rhythm and SPL control. I have not done this yet, but one practice to try is to continually swim lengths at a SPL, and then figure out how to increase or decrease from there. So if the base SPL is at the “0”, then do this:
0 – at the base SPL, it should be an easy pace
-1
-2 – focus on power, more speed
-1
0+1
+2 – less power per stroke, focus on rhythm
Repeat this. Don’t worry about the tempo.
Today, I have another lesson with Shinji on extending TI swimming for speed and time. TI has been running seminars for Advanced Total Immersion which is to drill with TI techniques for speed and distance. I’m hoping Shinji can help me to extend my TI skills to swim longer and faster. I also signed up for an Advanced TI seminar in January. Looking forward to taking that!

Coaches and Remembering What It Was Like Just Starting Out

I was going through my last TI training session and recalled an important moment. I remarked to my coach that many swim coaches tell you what to do, or describe something to you, but it never seems to work. I never seemed to improve enough with what advice I get from them. However, in the 3 lessons that I’ve had with my TI coach, I’ve improved so much, probably more so than in the years I’ve had going to Masters swimming.
He said something very insightful in reply, which was that a lot of coaches forget what it was like to be a beginner. They only know the present, which is at a high level of mastery of the skills and they attempt to describe that mastered state to us beginners, but we miss what it took to get to this state. Thus, we have little knowledge on how to get there, but only a description of the end result.
Total Immersion attempts to capture and teach the journey to mastery of swimming, and thus we do a lot of drills and exercises which may seem to be ridiculous to many, but there is a purpose behind doing these drills, and practicing and isolating the various elements of swimming mastery.
I find this to be true for coaches in all aspects of triathlon as well. I had a friend who was training with a pro-level coach, and he gave the whole group a training program that was based on HIS level of mastery of cycling and running. It was a program that was too advanced and assumed a level of skill and fitness which was not necessarily everyone’s level. This is bad because you may push someone to do something that they’re not ready for, and ultimately dissatisfaction for the sport and injury can result.
The best coaches are those who remember what it was like when they were just starting out. They remember AND can bring newbies on the journey to mastery of the essential skills of swimming, cycling, and running. Stay away from those who are insensitive to your current skill level, and treat all of their athletes like pro-level athletes. Working with these coaches puts yourself in danger of hurting yourself and inevitably cutting yourself short of the physical achievement you might get working with someone who is more sensitive to your individual needs.

Total Immersion: 13 Strokes for 25 Yards Baby Yeah

On Thursday, I practiced swimming efficiency and tried to maintain as low a stroke count as possible for as many 25 yard lengths as possible. Amazingly, I was hitting 13 strokes for the majority of the lengths, one 12 stroke length, and one 14 when I was getting tired.
Some notes:
1. Must be as relaxed as possible. But I can’t be so relaxed that when I initiate a roll to one side, I start rotating too far and become unstable. So I must rotate and then maintain stable position after I finish the rotation.
2. The stroking arm must move forward as fast as possible after hitting the end of the stroke. It must get to the cocked position fast, with slightly hunched shoulder, which drags my hips up in the water, and stops it from dropping too much and slowing me down.
3. The cocked arm must shoot forward fast into the water, which helps me go faster forward. This is in combination with the stroking arm pulling back with the hip roll.
4. The two beat kick really helps. I do a quick, hard snap on the foot that is on the same side as the stroking arm. This helps my hip roll snap over to the other side with great force, which lends force to the pulling arm.
5. Breathing is still an issue. Taking breaths slows me down and adds at least one stroke to the 25 yard length. In order to make 13 strokes, I usually only breathe once down the length. I need to practice breathing more, and when my coach gets back from Japan we will go through this.
Practice, practice, practice…in combination with tempo training, Total Immersion is working great!

RFID Timing Chips for my 5K!

I’m running my first 5K tomorrow and noticed they were using RFID embedded plastic timing chips! They’re pretty cool:


They sealed an RFID chip into this plastic strip, and there is adhesive on one end to attach it to your running shoe:

I wonder if they will start using these for triathlons. They look like they would be waterproof, but the strap would have to be longer and different to go around your ankle. But definitely they should work for run races.
Looks like they’re powered by RFID chips from Impinj.

TI Swimming with Shinji Takeuchi Third Lesson 9-18-09

My TI coach will be out of the country this next month, so I signed up for my next class for today so that I could practice some more things while he is gone.
Following my amazing feat of hitting 13 strokes for 25yards, I was actually able to hit 12.5 today! Well, the .5 was due to a Michael Phelps-ian half stroke near the wall before touching it; I was not sure if I could glide to the wall or not on my 12th stroke. Oh well – I’m still amazed that 12 strokes is within my reach now. Given that I started at 21, getting to 12ish shows me that I am not a failure at swimming, and that I just needed the right type of instruction to get there.
Some notes from today:
1. Last week’s lesson, my coach told me not to throw water back on the tail end of each stroke. It takes a lot of energy and is not really needed. It was not until today’s lesson that I felt that this was really true. Corrections in my form and using the two beat kick to generate power virtually eliminated the need for throwing water back and I could glide so much further on each stroke without such a tiring move.
2. Today it took me about 3.25 superman glides to get to the other side of the pool. Now 3 is my goal! See next entry on why.
3. I need to flatten my back more, which will make my body more smooth in the water. To do this, I rotate my hips slightly forward, which removes the arch in my back and flattens it out. Doing this on the superman glide made me glide forward a lot longer than with the natural arch that is in my back. I must research this more and also employ it in my regular swimming. This means a slight tightening in the stomach muscles to keep the hips rotated just enough forward while swimming.
4. On the zipper switch and over switch, I should think about the one shoulder shrug when bringing my arm up for the stroke. This movement is also tied to extending my shoulder blade forward. And while doing this, it drags my whole side, and thus my butt higher in the water! Cool no more butt dragging!
5. OK now that I am working on an overhead arm recovery with the zipper switch and overswitch drills, I should practice the overswitch by gradually dragging my wrist, my hand, and then my fingers through the water on the path to a recovery with my hand completely out of the water. All this with 90 degrees at the elbow.
6. With overswitch, I now have to pretend there is a target in which my hand will spear back into the water. My coach tells me that if I enter the water closer to my head, this is generally better for trying to decrease my stroke count. But for more speed, the target shoud be further out. He encourages me to play with different entry points to see their effects. But generally the target is about at the same level out as the other arm’s elbow.
He also notes that advanced swimmers going fast will have an entry point further out and the catch happens almost immediately as the hand enters the water, and the catch is strongly engaged by the bending of the forearm and hand at the elbow very far forward of the head. Thus, the pull back is very strong and is very long as it travels through more water.
7. As the hand spears through the target, it should stop going down but instead bend more forward and shoot to the front, with the hip drive and two beat kick helping to make the move strong. This helps with propulsive force going forward.
8. For drilling, I should pause in the overswitch, and then do a small exaggerated hop into the target. This is to get my feel for entering and hitting the target correctly. I should also practice this with the tempo trainer with what is called half tempo training, where the first beep is the pause at the top, and then the second beep is when I spear into the water and extend forward.
9. Using the tempo trainer, my coach suggests:
Half tempo training:
Start at 1.15 seconds, and then try to lower by .2 to .70 seconds
First beep, elbow up. Second beep, spear.
Full stroke overswitch training:
Start at 1.6 seconds, lower by .2
Arm must get into position before beep!
Underswitch training:
2.4 seconds
Zipper switch training:
1.8 seconds
Tempo trainer workout:
Recommend 1.2 seconds and try to swim 30/60 min at the same tempo.
Notes: He notes that you *will* get tired. So you need to figure out what is causing a particular slowdown of tempo. It could be stroke length, it could be the kick snap is too big or too small. The idea is to move the arms at the same tempo and train that.
He also recommends separating tempo trainer days and reduce stroke count days, so for example, swim either 500 tempo trainer or maintain stroke count.
10. For stroke count training, he recommended trying this workout:
Swim a few 25y sets and find baseline stroke count. Then swim a few lengths of 25y and try to change the stroke count: 0, -1, -2, -1, 0, etc.
11. In watching my video during one drill, I had a severe up and down motion during a stroke. My coach tells me this is because my stroke is not straight back but slightly down also. This is bad! So I should concentrate on pull straight back as much as possible.
12. My first breathing lesson: the idea is that I take a quick breath and then I watch the hand come down into the water, spearing through the target. This will take some practice for sure.
Lots to practice this next month, and looking forward to my next lesson which is more about breathing while swimming.

The Two Beat Kick Decreased My Stroke Count!

On Friday, I learned how to do the two beat kick. Previously, I had no idea what two beat was, nor four or six or two beat crossover kick was. I still don’t. I’ve read the literature and they try to describe in words a physical action and I still can’t get it. Someday I might, but not today.
In any case, my TI coach went over the two beat kick with me. It was a tough coordination exercise as I’m supposed to kick the foot that is on the same side as my stroking arm. I discovered that I was right foot dominant, and tended to kick that foot on either side. My coach then ran me through some exercises to focus on kicking the correct leg on a particular side.
Today, I went to the pool after that session and was determined to get the coordination of the two beat kick down. I ran through some of the isolation exercises for a while and thought I got it. So then I went to swim some normal laps, trying to maintain the correct form of the two beat kick. I would actually cock the leg a bit more than normal just to emphasize which foot was kicking, and attempt to keep my other leg relaxed and extended straight back.
On my first swimming length of 25y, I counted my strokes and made it down in 14 strokes! WHOA. This is a significant result. In my first swim lesson, my coach took a look at me, my swim style, my body shape and height, and figured that 14 would be a great goal for me. In weeks previous, I’ve been working hard at decreasing my stroke count, and seemed to hit a wall at 16. Most of the time, I was at 17 strokes to touch the far wall, and I felt like I was cheating a bit since I would just stroke less to let myself glide more. But today, while stroking normally and using the two beat kick, I made it down in 14 on the first try.
Well, I didn’t believe it. I thought I counted wrong. If you swim a lot, you know what I mean. Your brain wanders, you get confused as to which stroke was which number. It’s easy to lose count.
So I pushed off the wall and swam another length. This time it was 13 strokes! Now I’m starting to believe it. I swam another 2 or 3 lengths at 14, and then I got tired and/or messy in the technique and dropped to 15 which I swam for several more lengths.
As far as I can tell, the two beat kick does a few things for me. As I kick, the leg helps my hip rotate to the other side. Apparently, as the hip gets an extra oomph to rotate, that helps to drive the lead arm forward, and lend more energy to the stroking arm which is pulling back via connection to the hip. In other literature, I’ve read that kicking correctly also stabilizes the body more during a stroke. I didn’t feel this particularly as it seemed like the hip rotation was throwing me off kilter, but perhaps not as I was propelled forward more with each stroke than before using the two beat kick.
I’m looking forward to drilling the two beat kick more and seeing if I can more consistently maintain 14-15 strokes per 25y, or perhaps even less (12 anyone?).
