MarlinX will show you your movement curve both in the Sagittal plane (Straight up and down the boat) and Rotational (Sideways movements). In the Sagittal plane the Curve allows us to see your Connection, Speed and Acceleration of your drive, Hand and Body Speed off the finish and when you break your knees and many more little movements you may make during the stroke.
In the Rotational Curve the MarlinX will show you your movement to left and right showing you if you swing into the front-end or if you sit straight in the boat.
Multiple MarlinX's - Get the super image of your complete movements wearing a marlinX on your body, arms, seat and blades.
To note we do not know exactly the perfect curve and just because someone goes fast rowing one way does not mean it will work for you or your crew, this is evident if you watch single scullers at the Olympics, but they will all have something in common, a consistent stroke profile.
The MarlinX will allow the coach to see his preferred movement pattern and they will be able to guide the athletes to more consistent and effective stroke patterns, and guide a team towards a more synchronised boat.
Standard rowing technique
Rowing with a standard rowing technique Strong and continuous accelerated drive phase, hands away at a constant speed, body over until knees break, then controlled slide into the front-end, connection with the legs, holding the body still.
General mistakes - as you can see the acceleration is not as steep or as high, this is due to the rower opening their back on the front-end of the stroke, this is evident by the large double acceleration.
At the finish the large dip could indicate that the rower is moving hands and body together.
The slide and body movement forward is steady with no shape of a knee break.
The rower is controlled into the front-end.
Analysing the crew
Three elite rowers overlapping - from this graph you can see the very small details, that may not be picked up easily by the coach.
Even though the rowers are in the same crew you can see how they row very differently on their own.
The drive phase after the placement is relatively similar, but the hand speed and rockover in the recovery phase are very different - this would create timing and balance issues in the crew. The MarlinX can help show the athlete what their movements are and more importantly how they can make adjustments to sync with their other cremates, thus producing more speed for less effort
Crew rotational analysis
As you can see the from the rotational graph some rowers move around more than others. This may not be evident visually and obviously this movement will upset the balance of the boat. Being able to see this data allows the coach to show the athlete what they are doing and therefore produce more speed for less effort.
It would be expected that the closer the rowers are to zero the more stable the boat will be and therefore less energy will be lost in sideways movement.
As you can see from the blade movement the rower is making very different movements with their blades. Possibly accelerating the finish on the stroke side blade in the correction for missing the catch.
You can also see a lot of movement on the blade during the recovery this is possibly due to touching the water.
We would expect the 'ideal' stroke to be 2 perfect boxes with flat lines in-between
App Screen display
The App allows you to see your basic information speed, rate, total workout time and current split time for that piece.
On the next page it will show your body, blade and boat movement (boat check) or just one or two that you choose.
You can also connect your heart rate band to the app allowing you to see all your athletes heart rates in one place
*an iPhone can currently only pick up 8 bluetooth devices at the same time, so you will have to select which one to pick up
The Full Image of your rowing.
Attach multiple MarlinX's to your body, hands, seat and blades to see all of your movements.
If you are sending your data to a remote coach this will show him everything you are doing better than seeing you in person
Analysing Tom; watching the video Tom is rowing pretty well, but we can see on the graph a sharp point at the catch, looking closely at the catch you can see that Tom's knees come slightly passed the vertical, this makes him slightly bounce in and out of the catch. This also means that he moves on the drive phase then connects and drives this is why the acceleration line is not perfectly straight.
On the graph you can see at the finish a longer time spent in this zone, as you can see on the video Tom stops his hands at the finish, some would say he might want to keep them moving.
You can the see the graph shows no distinct separation between hands body and slide and on the video you can see that Tom needs to separate - holding his knees down longer letting the body rock over before the knees break.
What are we looking for in the graph.
