Measuring Exhaustion and Readiness
Philipp Kalwies talks about the risks of over-training and how an athlete can measure their body's level of exhaustion. He believes that the right amount and intensity of training is the key to successful performance for athletes. In this talk, he discusses the testing of a new device which promises to conveniently deliver data that athletes need to measure their exhaustion and intensity and help to find the right moment for their next workout.
What Causes my Heart Rhythm Disorder?
Dr. Mark Drangsholt is a long-time self-tracker who also teaches evidence-based medicine at the University of Washington. He has tracked blood pressure and exercise, atrial fibrillation and what triggers it, deep sleep and sex, diet and body fat. In the video, Mark shares what he learned about his arrhythmia triggers, and how his self-tracking data helped sway his cardiologist to do a less invasive procedure. He also makes a great case that Quantified Self experiments can be more scientifically valid than many of his colleagues would like to admit.
Butterfly Project: Swimming Goggles To Measure Heart Rate
Hind Hobeika is a swimmer and an engineer from Beirut. She wanted to monitor her heart rate while she was swimming, so she built goggles that sense and display her heart rate in real time. It’s called the Butterfly Project. In this talk, she describes how she designed and assembled the goggles, the challenges she faced, and future prospects for the project.
Improving My Blood Pressure With Anaerobic Interval Training
Siva Raj noticed his blood pressure rise after he turned 40, which was a wake-up call since he watched his father have three heart attacks in ten years. He then tried to figure out how to normalize his blood pressure, so he began doing anaerobic interval training. In this talk, he shares his success doing the training using Revvo, a small exercise pack.
Using Heart Rate Variability to Analyze Stress in Conversation
Paul LaFontaine measured his heart rate variability during meetings to understand what he calls "vapor-lock" -- a relatively important person asking another person a difficult question of which he/she knows the answer to, but is unable to remember it in the moment. Using the HRV measurement was a good way for Paul to capture his stress levels during meetings and investigate how to get through this issue. Through this study, Paul learns a great deal about himself and how to prepare for "vapor-lock" in future meetings.
ECG and Activity Monitoring: What Can We Learn?
Maggie Delano wanted to see what she would find out if she tracked her electrocardiograms continuously over time. Electrocardiogram is a measurement of ones' heart. A doctor would prescribe you a device that could measure your electrocardiogram when you have any sort of cardiovascular dysfunction. In this talk, she explains what an ECG and activity monitoring is and what she has learned from it.
A Million Heartbeats
Crt Ahlin is from Slovenia and he studies statistics at the University of Ljubljana. He is also a fan of life logging. Crt became interested in the Quantified Self movement about three years ago when he had some health issues. In this video, he talks about visualizing heart rate data and a possible way to measure daily values with a curve that could also be used as a baseline for comparisons.
