It has been 9 months since I first shared experience to track tennis performance with Apple Watch. Backing up by popular demand(Surprised so many visitors found this blog from search engine all over the world), I’d like to take it further with a more in-depth review, of my own experience tracking and analyzing my tennis workout with the Swing app.
This blog post is aiming to provide a step-by-step guide to perform advanced analytics on swimming data, captured by Apple watch. Microsoft PowerBI and Python on Jupyter Notebook are the primary tools to prepare, analyze and visualize the data.
You will learn how to export the workout data efficiently to your PC, make necessary data transformation, and understand what metrics and dimensions are available. Then I will walk you thru how to analyze the data to answer typical questions related to why certain behaviors happened. You will then see my preliminary attempt to use advanced analytics tools to predict future swimming performance.
Most importantly, you will find quite a few reference articles related to this topic, hopefully fulfilling your intellectual curiosity.
It is also the #3 articles of a series, the previous articles can be found here:
The “life-long learner” is a pretty sexy title.
Over the past few years, I have received feedbacks, from both trusted and the anonymous sources, that self-improving seems to be one of my characters.
As a normal human being, I was flatted; As an analyst, I can’t control the skepticism: Is this a filtered bubble?
What does it really take, to become “life-long” learner? – Let me tell you my version:
Sleep tracking isn’t new. But what’s unique about using Apple Watch?
Sleep is the single most important activity for a normal human being, measured by time spent. Having a good night of sleep usually means a jump start of the day. On the flip side, bad sleep (or no sleep at all) will lead to serious implication – both physically and mentally.
In this blog post, I am happy to share my story of using the Apple Watch + 3rd Party App to better measure the sleep. Hopefully, it will inspire you to pick up a few things here and there and take action to make your own sleep better.
Playing tennis has been a major part of my adult life: It is fun, competitive and a truly global sport. More importantly, it has shaped my character and my social network. Over the past 18 months, I have been using my Apple Watch to track, and subsequently, to analyze my tennis performance along with swimming
In this post, we will cover the background, the pros and cons of different apps, and how the additional metrics playing a role in my mindset shift.
I have recently wrapped up 5 years (4 years + 9 months to be exact) of analytics career in a Fortune 100 company. In this precious in-between moments, I’d like to take the time to reflect on 3 lessons learned as an analytics professional in the digital marketing industry.
You are a proficient Microsoft Excel user – vlookup is an appetizer, pivot-table is the main course, and VBA/Macro is your dessert. And your company just gave you an upgraded Microsoft 365 subscription, and a brand new version of Excel is just being served. You are wondering – “What’s new?”
As an analyst living and breathing with Excel, PowerPivot and PowerQuery are the two killer features, period. I’d like to share my story on how you can save time and make your spreadsheet work more efficient.
2017, I have been benefited greatly from the digital analytics association(DAA), including the eMetrics and certified web analyst destination, and five local chapter events in Toronto. This post breaks down these events I went to, what are they, how do they help me, and why they matter to me during the career development for a digital analyst.
Being a part of a bigger community
Earlier in my career, maybe 10 years ago, I had a similar feeling surrounded by a group of peers, sharing similar interests – tennis. We achieved great things together – workshops, tournaments, etc. That experience not only shaped my life-long hobby, but also gave me an opportunity to meet, work and have fun with a few friends that I am still contacting with now.
Back in 2017, I have a similar feeling – “being a part of something big”, after attending 5 local Toronto chapter events from DAA.
Back in February in my first post of using Apple Watch to track swim, I wrote about the metrics available and usage in the Apple Watch, a handful of data quality challenges, and my plan of using data captured to improve performance. After logging another 22 workouts since Mar 2017, I would like to give an update, and also share a few more new interesting lessons learned.
