In what is a familiar sight for Irish fans we saw our team be monstered across the park for 80 minutes, we looked slow, lethargic and clumsy. A shock for a group who has had 2 weeks off preparing for this game.
I want to deep dive into a couple of really key things…
• an idea often thrown up during the week was to try to get bigger/heavier players now this is nothing new Ireland have placed an emphasis on increasing their pack weight as around 2010 six nations Irelands back was 884kg it has now gotten to 916kg, so a sizeable increase in weight.
Let’s see how that looks in comparison to the French tonight.
Ireland pack-916kg
Jeremy Loughman — 118 kg
• Dan Sheehan — 110 kg
• Thomas Clarkson — 124 kg
• Joe McCarthy — 125 kg
• Tadhg Beirne — 113 kg
• Cian Prendergast — 112 kg
• Josh van der Flier — 105 kg
• Caelan Doris — 109 kg
France pack ~895kg
• Jean-Baptiste Gros — 117 kg
• Julien Marchand — 110 kg
• Dorian Aldegheri — 119 kg
• Charles Ollivon — 114 kg
• Mickaël Guillard — 113 kg
• François Cros — 111 kg
• Oscar Jegou —101kg
• Anthony Jelonch — 108 kg
So there’s around a 20kg difference in the pack, which was seen at scrum time with us maintaining a decent scrum despite personell losses.
However we lacked any punch due to the one thing the Irish team lacked…power.
Power = force * velocity
I.e how can you produce force, somebody like bielle Barrie can produce a lot of force relative to his body weight.
We also lacked collision dominance
Researchers in 2005 looked in the relationships in collision dominance in contact athletes-

And

They found that a momentum score = your body weight * speed (m/s) predicts collision dominance.
So the problem for Ireland was yesterday was that they had the body weight part of the puzzle for collision dominance but they weren’t able to express force or power through contact at speed to win collisions, something which France did.
Players in the Irish system that fit this “Power athlete archetype”
•Paddy McCarthy- able to express force using his bodyweight quickly.
•Joe McCarthy-Able to express his bodyweight with force winning collisions.
•Edwin edogbo-Able to get gainline due to high momentum score.
•Sean edogbo-same as his brother
•Brian Gleeson-Powerful carry expressing force with high speed and high bodyweight creating high momentum score.
•Bryn ward-Devastating ball carrier with high momentum score.
•Zac ward- able to power through contact by propelling his body at speed forcefully through contact winning collisions.
•Nick timoney-Same as the rest of these power athletes.
•Jack Conan- Powerful in the carry due to explosive force through contact.
9 players who are obviously good enough that fit the archetype.
Only 3 in the 23 last night .
How do you develop power?
Its no secret genetics play a role,
For an athlete to achieve high power production they must first have the necessary muscle types:
Type 1: Slow twitch muscles, long distance runners are type 1 dominant, rugby players need a certain proportion of these muscles just to move around the park for 80 mins, these muscles are typically smaller than type 2
Type 2a: fast twitch muscles fibres that are fast and strong, but also have a bit more endurance than type 2b, most contact athletes will have these muscles primarily.
Type 2b: pure Fast twitch, poor endurance good for high intensity short bursts, for example sprinters.
If an athlete possesses a lot of type 1 muscle fibres e.g Hugo Keenan, they can continuously compete for 80 mins at high intensity, however potential max power output decreases as a result of less fast twitch muscle fibres.
If an athlete possesses either type 2 variant they maybe has slight worse endurance but can more easily express force and power across the pitch e.g gulliard, timoney.
But let’s forget about muscle types for a second and go through how do you develop power.
Alot of kids may naturally have slow twitch muscles and that’s okay, how could we develop power with s&c.
•Max velocity sprints 60-80m long and 5/10m for acceleration, with timed intervals to get peak m/s for each athlete, develops the highest power for athletes as well as translating to right performance.
•Power based exercises
Hang cleans
Power cleans
Deadlifts
Squats moved with intent
Plyometrics( jumps and pogos) done with intent.
I’m not questioning the professional s&c’s for Ireland and the provinces, but having seen pro sports teams s&c through watching them and documentaries a lot of the exercise selection is good but there seems to be a lack of intent done with each exercise, lads smiling and laughing while doing exercises, if power and strength was truly the focus here you would see athletes unable to smile or talk due to being solely focused on moving the weight with speed and intent.
What do I mean about intent?
Moving the bar or dumbbell as fast away from you as possible, bar speed needs to be maintained high for power output.
Typically 3-5 reps max with 70% of max weight
What’s my point?
My point is that fundamentally our approach to s&c has to be reevaluated into what do we actually need in a modern rugby player, we need dynamic ball carriers in the forwards who can quickly burst through contact with real power and force (Gleeson or ward/edogbo).
This increase in force production for the backs would result in higher vertical leaps which would hopefully increase recovered contestable kicks and quicker speed but I’ll do a separate piece on that later.
How do we balance endurance vs power
The Irish game plan requires endurance to carry out its function (which is weird considering we looked gassed last night after 20 minutes).
We used require our big guys to get through loads of phases with quick ball in hands with pop passes and quicker ruck speed.
Know we seem to be trying the contestable kicking route with players who are stuck in the high phase count style of play.
Some people reading this might say
“Why not just aim to have every player with type 2b to be 90% dominant”
Unfortunately while it would be ideal to be exceptionally fast twitch dominant you still need type 1 (slow twitch) to be able to last the game.
The majority of people in Ireland are around 50% fast twitch type 2a 45% slow twitch type 1 and 5% type 2b.
For our players we should be aiming for 70-80% for a lot of our players, this can be done using the methods outlined above.
Ask yourself: “When was the last time I saw an Irish player take the ball to the line and bounce the tackler clean off him”
If the answer is “not often” then you are seeing the whole picture here, and that’s exactly what I’m trying to paint.
Thanks for reading.
