I did may second MAF Test tonight, 7 weeks after I did my first one. You are supposed to do these tests every 4 weeks but it has been so hot in Japan I could not face it. As you can see below my times have gotten slower than my first one. This is disappointing and I can only assume that it is due the humidity and keep on training aerobically.
Maximum Aerobic Function (MAF) 140 bpm
Average Heart Rate 138 bpm
Time in zone 76%
