Be Explosive for 4 Quarters

There is a saying in sport that goes "you can be fast, but can't be fast for long"...or can you?

The ability to repeat your top speed, or close to, is pretty much the golden requirement for AFL hopefuls these days, with short bursts of play alternated with short bursts of rest on the bench.

A quick energy systems lesson first.

There are 3 main energy systems being alactic, lactic and aerobic.

The alactic system (a short, full intensive sprint) is improved by increasing the amount of creatine phosphate that your muscles can store and use which might mean you can sprint faster for the same distance, or maintain your top speed for a longer distance.

Now we probably know that its our fast twitch muscle fibres that do the job for fast and explosive movements but did you know that your slow twitch, endurance based fibres, can also assist in these endeavors.

Your slow twitch muscle fibres can actually produce as much force as your fast fibres but they don't do it as quickly.

If you're fast twitch dominant then you might be able to run flat out for 40 meters before you start to slow down. If you are extremely fast twitch dominant (like me fortunate and unfortunately) it means that you're speed will drop off very quickly once your fast fibres fatigue.

If you develop your slow muscle fibres which as mentioned above are as strong as your fast fibres but take a little longer to hit their stride, then once your fast fibres start to fatigue, the slow fibres can take over and you'll be able to maintain your top speed, or close to, for longer.

Another bonus of increasing your slow twitch fibre size is that your muscles will improve their ability to work aerobically. When you're also anaerobic dominant (again like me but a lot better this year!) then you'll have a great first effort sprint but you'll gas out very quickly and take a while to recover. When your muscles get better at utilising oxygen as an energy source then you'll improve your repeat speed from faster recovery, you won't use as much energy during your most intensive efforts and you'll also improve your ability to use fat as fuel which can also improve body composition. All sorts of wins there!!

OK, so to train for this you need to use the tempo and explosive method in the gym which I've got from Joel Jamieson (there's a 4 week conditioning program on that home page I did in the off season that cut my 2.4km time by 30secs!). I've been running this for the last month and have used bodywieght squats and jump squats.

For the tempo method you do sets of 10 reps but each rep is 2 seconds down and 2 seconds up which means you'll purposefully have to slow the movement down as you want it to be "even" and controlled the entire time.

For the explosive method I'm using jump squats which are done for sets of 10 - 15 seconds.

Here's the program Joel prescribed for this:

Week 1
Day 1 - Tempo 4 x 10 with 45secs rest between sets + 8 - 10mins active rest + 4 x 10 with 45secs rest between sets (remember 2 secs up and 2secs down!)
Day 2 (3 days later) - Tempo 5 x 10, 45secs rest btw sets

Week 2
Day 1 - Tempo 4 x 10, 40secs btw sets + 8 - 10mins active rest + 4 x 10, 40secs rest btw sets
Day 2 - Continuous aerobic work (boxing etc) x 15mins @ 120 - 160 beats per minute
Day 3 - Tempo 6 x 10, 40secs rest

Week 3
Day 1 - Explosive 4 x 10secs, 40secs rest + 8 - 10mins active rest + 4 x 10secs with 40secs rest
Day 2 - Continuous aerobic work x 20mins @ 120 - 150bpm
Day 3 - Explosive 5 x 10secs, 40secs rest

Week 4
Day 1 - Explosive 6 x 12secs, 35secs rest + 8 - 10mins active rest + 6 x 12secs, 35secs rest
Day 2 - Tempo 4 x 10, 35secs btw sets +  8 - 10mins active rest + 4 x 10, 35secs rest
Day 3 - 6 x 10secs, 35secs rest

Week 5
Day 1 - 8 x 15secs, 30secs rest + 8 - 10mins active rest + 8 x 15secs, 30secs rest
Day 2 - Tempo 5 x 10, 30secs rest + 8 - 10mins active rest + 4 x 10, 30secs rest
Day 3 - 6 x 12secs, 30secs rest

Week 6
Day 1 - Explosive 5 x 15secs, 20secs rest + 8 - 10mins rest + 5 x 15secs, 20secs rest
Day 2 - Explosive 5 x 12secs, 20secs rest

I've just finished week 4 with a big week 5 coming up - it will be near death that Monday session!!

UPDATE - I'll be doing these again in the coming months as part of my own pre-season training.

Nat Fyfe Transformation

Like most of you, I salivate when Nat Fyfe is on - I believe he has over taken Garry Ablett Jr as the games best player. H e was drafted as  68kg-er!

I actually remember when he debuted as I heard a whisper he was a goer and traded him into my Supercoach team.

Still pretty skinny after his first pre-season with the Dockers, he took one of his trademark pack marks for his very first AFL goal. As hard as he tries to, there's still not much to actually flex at this time!!

It was probably his third year that I started to notice his body changing rather dramatically, relative to his previous body, which was wiry and thin.

The bulk he put on through his hips and upper legs was extraordinary, as evident below:

If you're a budding footballer and you're looking to bulk up in the off season, this is what you should focus on. Instead of having 3 upper body days, do 3 lower body days.

You'll get faster, increase endurance, increase injury resistance ad be able to handle physical pressure in close quarters during a game.

It also shows that if you really knuckle down for 2 - 3 off season's then you can really make all the muscle gains you need. You don't want to be heavy that you can't cover ground like you normally do but you don't want to be so light that you can't compete in 1on1 contests and be pushed off the ball easily.

In-Season Training Musings

If you remember back to earlier this year I had a what I thought was minor blow out of my lower back. As it turned out it got progressively worse and resulted in me not being able to run, sprint and jump, as well as pretty much next to zero leg work in the gym, for around 6 weeks.

It only came good for practice match number 1 in mid March so I've spent the last 10 or so weeks trying to get myself back to the strength level I was at pre-back blow out.

So from that I have needed to alter my training to fit where I'm at physically. We're 5 games in with the 6th tomorrow and the back has been fine for the most part in each game but it can pull up a bit stiff in the days following games. Oh, and I'm almost 37 and not the spring chicken I used to be!

So my aim is now to be as fully rested for game days as I can be so my training is sub maximal at best and even when my HRV app says I can train intensely, I will only train with "intensity" on a Tuesday or Wednesday.

With all of that in mind, here's what I've been up to:

Rehab - for my lower back rehab I started using a technique that I'd been reading about for a while now but had never actually performed called Be Activated which is a muscle activation technique made popular by a South African physio Doug Heel. I'll probably do a long winded post on this very soon but you can read a bit about here. He's just come to Australia for the 1st tome this past April so it's very new to Australia but of course Jonny-on-the-spot (me) had his dvd's prior to that as I couldn't attend any of his courses. Anyway they're pretty fantastic and now serves as much warm up for training and games.

Lower Body Strength - so even though my lower back came "running/sprinting good", it has taken a lot longer to become "gym good", especially in regards to deadlifts and squats. The back just wasn't feeling spinal loading that well  so I had to find some alternatives. So to train the deadlift pattern I opted for romanian deadlifts after working up to those with 1 dumbbell deadlifts off a step - an exercise I use with 1st session beginner clients in the studio - that's how little loading I could use initially. I worked these up pretty slowly and have just "maxed out' this week on those. The 2nd alteration I had to make was to get rid of back or front squats and use a modified landmine / belt squat which worked sensationally up to a point.

It's a bitch to set up and to be honest you probably couldn't get it happening in a public gym but I own my studio so I can do what I want!! I think this set is with 105kgs which I could do no worries but when I tried to amp it up to 125 it was too hard to load up and move the step away on my own - with a partner it would be fine though. No spinal loading, no worries.

Lower Body Explosiveness - there is a huge correlation between standing long jump and acceleration sprinting speed.

 
So as my pulling up from games ability has somehow left me in the last year and a bit (upsetting), I need to find alternative ways to train speed. I'm playing deep full forward out of the square this year so all my running is pretty much 90 - 95% sprints during a game so I only need to supplement that with something to assist with speed development. So I have just come off a 3 week cycle of sub maximal standing long jumps which I will retest next week. Training sub maximally means you train at around 70 - 90% and the focus is on practicing the lift but with limited fatigue build up. I did 8 x 3 at 75% of pre tested distance, 8 x 2 at 80% then 8 x 2 at 85%.

Program Design - now that I have built my strength back up I can now program for strength maintenance through speed strength and strength speed methods but also with some auto regulation thrown in to manage fatigue and to make sure that only quality work is being performed to again minimise fatigue. I've made up 3 parameters that I'll use in my training:

Speed - more reps then secs time per set (5 reps in 3secs for example)

Power - same reps in same secs time per set (5 reps in 5secs for example)

Force - less reps then secs time per set (2 reps in 5secs for example)

I haven't quite worked this out yet but I have a fair idea of what my max numbers are so I can gauge what training effect I'm after for that day (speed, power or strength) then use the recommendation from above for whatever I choose to train.

Schedule - just a quick bit on my schedule you must be aware by now that I don't train with my team because of work commitments so I can set my own schedule which so far this year has been upper body Tuesday, lower body Wednesday and Upper body again Thursday which seems to be working well as far as being fresh for game day is concerned. I can't train everything I want to train though but that can be a good thing as then I'm only including the absolute necessities and seeing as though 80% of your results will come from 20% of the things you do, making that 20% is critical.

Amateur vs Elite GPS Comparison

Today I just want to point you towards 3 articles I've come across the last few weeks.

The first one is GPS data collected from an actual AFL team over 4 quarters from a world renown strength and conditioning coach's site Mladen Jovanovic and can be found here.

It can be quite hard to read but if you click on the csv file link in the first sentence you can have a look at it in excel spreadsheet and it makes a bit more sense.

It covers 199 different categories!

Do take some time to have a good look at it though as it may just help you with your own game in regards to what you do and don't do on a regular basis.

The second and third articles are both from the VAFA (the best amateur league here in Melbourne) that shows the GPS readings from 2 of their top line players and can be found here and here.

It shows the following for each player:

Amateur Player - Jack Bull

Position –Nomatic (midfield, wing, interchange)

Total Distance – 15.06kms

Average Speed – 6.21kms/hr

25% of running time @ 13.5km/hr or faster of which 600m of that was above 21.6kms/hr which is zone 6 running (highest velocity/top speed)

Sprint Efforts – 106 @ 16kms/hr or faster

Amateur Player - Tom Humphrey

Position – utility but deep defender who goes with the best forward runner

Total Distance – 14.7kms

Zone 6 Running – 285m

Top Speed – 30.71kms/hr

Walking – 1km more then Jack from ball being at other end

You constantly here of mates saying "this bloke could have played AFL if he wanted to' but that's simply not true. "Wanting to" includes wanting to work harder then everyone else and that;s exactly what you need to do to reach some of these numbers.

These amateur blokes are reaching AFL-type GPS readings but certainty aren't playing AFL but it shows how close you can be to 'the standard" but so far away for 1 reason or another.

GPS units are becoming more common in local/amateur footy so if you have the chance to get a hold of one definitely give it a go and see how you fare.

Heart Rate Variability

Keeping to the subject of personalising your own training to fit you and no one else, we move to heart rate variability (HRV) testing, which refers to assessing your physical and mental state of mind. This can be done through specific iphone app's which can help dictate how hard you should train on a given day. It could replace, or be combined with, using rate of perceived exertion and the manual method of monitoring fatigue during the season of which I have posted about previously.

To start with there are 2 regulatory mechanisms of the body, the autonomic nervous system (ans) and the neuro endocrine system (nes). The ans is then broken down further into the parasympathetic nervous system (pns) and the sympathetic nervous system (sns). Both of these are part of the fight or flight equation:

PNS - Flight

SNS - Fight

The ANS is stimulated when the brain senses any form of challenge and once it is activated, it stimulates the output of cortisol, a stress fighting but fat storing hormone. Adrenaline is also increased which keeps us alert by increasing heart rate and blood pressure by quickly mobilising energy reserves, while cortisol works more slowly to help replenish energy supplies.

All of these adaptive changes is called allostasis which refers to maintaining stability, or homeostasis, through change.

I bet we've all played with the bloke who has a bit of white line fever and gets quite ramped up during games - this is from him being in a very sympathetic state which for competition, is actually essential.

On the flip side we've all played with that bloke who looks like he's barely awake who pretty much stays in a parasympathetic state regardless of the "challenge'.

The biggest trick though is to be able to interchange through both the parasympathetic and sympathetic nervous systems.

So you're on the ground and going like a bat of hell (how bad was Meatloaf that time?) and you blow up and it's time to head to the bench to recover. In order for you to recover in as fast a time as possible you need to swiftly move into a parasympathetic state to slow your rate down and to start shifting your body back to homeostasis (normal).

Thinking long term, training with high volumes and intensities means you enter a sympathetic dominant state very often which is fine, but during this time when you feel a bit rundown, have trouble sleeping and have a lack of appetite compared to normal, then you're getting stuck in the SNS and not shifting back to the PNS. This means that you're not really recovering enough and sooner rather them later, you're body might make you take a break through illness, or even injury.

Taking heart rare variability is something you do everyday to get a gauge at how your body is tracking against your playing stress, training stress and outside stressors because they all add up. Once you overflow the "stress" cup, it can take a while to get rid of this excess build up. This means that relationships, food quality and alcohol can also have a big effect on your readings.

I have recently started using an app called HRV4Training for my own heart rate variability. There are others on market such as bioforce and iathlete that are the go-to app's for this but they require a compatible heart rate monitor and mine is non-compatible.

HRV4Training provides a lot of funky readings but the ones I look at is the day's reading, how it compared to yesterday and also how it compares to my baseline. I also keep track of resting heart rate and rMSSD reading too which the creator told me is the equivalent of a HRV reading from the other app's. The app does this in 1 single 60sec measurement that you'd take immediately upon waking. I do it while I'm actually still in bed!

The home screen tells you your assessment today, yesterday's assessment and you're baseline based on the last 7 days.

It provides with 1 of 3 tips to program your training for the day.

#1 - Your condition has improved since yesterday and is above baseline so go hard today

#2 - Your condition has worsened since yesterday and its below baseline so take it easy today

#3 - Your condition has worsened for 2 days in a row so take today off.



So the app takes your daily reading then tells you what you should do with your training today. In the above image you can see that I registered 7.9 which was lower then the day before and also lower then my baseline so it suggests I take it easy today. So instead of doing that hard repeat sprint session I had planned, I would opt for a recovery based session today so hopefully I improve for tomorrow and can go hard then.

Now you don't have to live your life by what it tells you to do, it might be game day where it says to take a day off, but what you can do there is go back to your monitoring and rate of perceived exertion tables and find correlations between your scores and your 'low' days which should be able to help you alter your training and lifestyle accordingly.

UPDATE - I have read many times that you should never go against the HRV reading and yesterday was the proof in the pudding. At the moment I've just started a depth jumping cycle which requires pretty much stresses the nervous system more then anything of which I started last week. I was coming off a day off and 2 full days since my last depth jumping session so I "should" have been rested and ready to go. I did nothing on the weekend or new years eve so there was no reason to not get a good HRV score come Monday.

My test gave me a reading of 7.4 against the previous days 8.4 against my baseline of 7.9 which said take a day off training but being as it's the off season then I can train and make up the rest later if I need to.

About 3/4's of the way through my workout which was feeling fine, I felt a 1% twinge in the lower back between sets. Something I've probably felt a million times before without repercussion. Except this time! Language Warning!!

I did my 9th set of power cleans and the back went which it does probably once a year in the 1st part of the year when my training load is at it's highest but I was determined not to do it this year...and failed miserably.

The lesson is to not go against the HRV reading so if it says take it easy then limit any activities that have a history with making you sore, run down or injured.

Rate of Perceived Exertion

In the past I have mentioned the use of auto regulation in your training which refers to training "on the fly' but using a set point of load or rep speed to decide how far and how hard you'll push a particular session.

For example you might have a max of 100kgs but you reach 90kgs and it feels pretty heavy. The speed is slow so you have a fair idea that today isn't one for setting personal bests, or even trying them, so you might just do a few extra sets of 2 - 3 reps at 85 - 90% of that 90% and call it a day. 

Rate of perceived exertion is a similar concept but you assign "perceived effort level" to each exercise. You might have used %'s before but this method can be flawed as you would base the %'s off your max, but as described above, your 1 off max isn't your everyday max, so that moderately hard 85% day can quickly turn into a ball breaking 95% day which, in regards to recovery, could stuff your whole week up!

RPE refers to how hard a set feels or how far away you are from failure you are in regards to "reps left in the tank'. For example you might do a set of 5 reps @ 80kgs. After the set you think you could probably have done 7 reps at that load.

The table looks like this:

RPE x 10 = 0 reps left in the tank
RPE x 9 = 1 rep left in the tank
RPE x 8 = 2 or 3 reps left in the tank
RPE x 7 = 3 reps left in the tank with good bar sped and acceleration
RPE x 6 = fast bar movement with minimal effort

So instead of working up to a % of load which can be different each day as described above, work up to a rep number at a particular RPE such as 5 reps at a 9 RPE where you'd finish the exercise when you perform a set at a load that will allow only more rep.

Then move on to your assistance work.

To take this a step further you can assign RPE 's to your other sessions too for speed and aerobic / anaerobic conditioning and include this in your activity load monitoring from last week to again pick up on trends against increased and decreased performance.

Monitoring Fatigue During the Season

After a 3 - 4 month flogging it's finally time to get some actual game time with practice matches being scheduled to start in the next week or two for most clubs.

There's nothing like that first 5 minutes of the first practice match, especially if it involves a big tackle, to really take the wind out of your sails in a pinch!

With practice games comes 1 solidarity weekly goal, with that goal being game day Saturday. During the off and pre-season you can train continually regardless of fatigue build up (to a degree) with the end goal being how you perform in the months after you started training (during games).

This means that you can train any day you like and you can induce pretty much as much fatigue as you like because you can always throw a rest day or 2 in the mix. If you're a little tired going into the first team training session of the week then it's not the end of the world.

Come the in-season though and this all needs to change because you need to "peak" each and every Saturday for the next 20 - 25 weeks.

This will require personal fatigue monitoring each and every day.

All AFL, VFL and some of the upper amateur teams use some form of athlete monitoring to individualise player training loads so as not to prescribe too much for those not fully recovered, or too little for those who had less game time and thus less fatigue to recover from. If you have access to GPS data for training then this can work even better but 99% of us don't.

The advantage of using a personal fatigue monitoring is that by keeping track of various internal and external factors, you can correlate these with periods of tiredness and less then stellar performances on game day.

This means you can avoid insanity - doing the same thing and expecting a different result.

So each day as soon as you wake up you'll monitor the following:

Sleep - Duration of Sleep + Quality of Sleep. You could also track if you dream or not which is the point of your sleep where the best regeneration occurs and you don't have to remember what you actually dreamed of, just if you did or not.

Mental Stress - had a blow up with the missus? Someone stole your seat on the bus? Anxious? Big exam coming up? All these things can have an affect on your stress levels and thus performance output.

Soreness - lingering soreness from the weekend? New soreness from training? Nagging back pain that comes and goes?

Fatigue - hopefully you know what you're peak fitness feels like when you're at your at your absolute freshest.

Motivation - to train and to play. Are you keen as mustard to play today or happy that game day is still a few days away?

Mood - compare this to your normal mood/personality.

Apart from hours of sleep, rate each of these 1, 2, 3, 4 or 5 with 1 being the best so with 6 sections to assess the highest score you can get is 30 which means you get the week off!!

Resting Heart Rate - take this each morning in bed as soon as you wake up. Take a 10 second reading and multiply it by 6.

Protein - 1 serve equals something about the size of the palm of your hand.

Veggies - 1 serve equals 1 cup

Fruit - 1 serve equals 1 piece or a palm size

Cheat Food/Drink - refers to all processed foods that come in a box and all drinks that isn't water or a low sugar sports drink.

Beers/Ciggies - put in how many you had on each day...BE HONEST!

Again what you're looking for is the correlation between your high scores, poor performance and (hopefully not), injury.

This way you can avoid the pitfalls next time around and at a minimum it will make you very aware of things like getting to bed earlier.

I'll be starting mine Monday morning.

Here's what it looks like in table form (click on to get the full table):

UPDATE - Even at the elite level, if you can have your best players play most, if not all games, then you'll have a successful season. At local/amateur level this is even more crucial because we don't have 30 senior made players on every list so games lost with injury can destroy your once optimistic finals aspirations. I'm actually in the process of putting together a pretty detailed but (hopefully) easy to use athlete monitoring program for local/amateur teams to use that won't require a professional strength and conditioning coach to use. Let me know if you're team might be interested in this!
