Yay! I am finally getting the hang of the up-sweep arm movement for butterfly, defiantly not a skill that you learn over night!
This will be my final session on the up-sweep and next session I will be focusing on another aspect.
This session was planned with reference to Luebbers, M (2013).
Design of session:
1. Start with the hands at the entry position.
2. Sweep them down and in under your chest, almost touching your thumbs and index fingers together as your hands reach mid-chest.
3. Push them back toward your feet and apart, like you are trying to push the water from the middle of your chest over and down each leg.
4. As hands and arms reach an almost full extension as they move past your waist, throw your hands up (out of water) and out to the side, throw hard enough that arms almost automatically swing over the surface of the water toward the entry position.
This session will follow Adam's closed-loop theory (Adams, 1971), which has 2 key neural components: a memory trace, which selects and initiates an appropriate response; and a perceptual trace, which acts as a record of the movement preformed over many practices. During and after an attempt of the movement, feedback and knowledge of results enables the performer to compare the movement with the perceptual trace. This approach will result in improvement of the skill, as I will be evaluating and comparing the movement pattern, then practising a certain aspect to result in improvement of this aspect.

Statistics/ detailed information collected:
30 up-sweep butterfly movements were preformed.
3 lengths of butterfly without stopping were preformed (in total for the whole training session not in a row).
More sessions/practice is needed to get my kick and arms working in time with one another.
1 hour practice session.
Reflection:
Yay!! I finally feel like I am making progress with the butterfly stroke, and can see light at the end of the tunnel. Today was the first time I could do the arms, breathing an kick all at the same time. I could do a whole length without stopping, just got to work on timing now and practice, practice, practice! Adam's closed-loop theory (Adams, 1971) was used really well in this session as it enabled me to build on my skills learnt from previous sessions. Then receive feedback and build on the skill as a whole to improve it.
