Tennis - experimenting a bit

Some more data in our quest for decent training sessions while keeping good control. All afternoon sessions in relatively similar conditions, same trainer, same intent. Maintaining the same intensity throughout was of course difficult in the presence of lows.


Tennis Training Oct 29 -2014 from Pierre Vandevenne on Vimeo.

 First case - standard meal, including 60/70 grs of carbs as rice. Normal meal-spike. Pre-loading with 60 additional grams of fast carbs in prevision of a 1 hour training. Coming from a lowish pre-meal 70 mg/dl. Pre-training spike perfectly timed. IG complete collapse after 35 mins, BG after 15. Post training too high.
Lantus 15 - 7:15 PM       Novo  4 - 1:30 PM

 Second case - standard meal, including 60/70 grs of carbs as rice. Flat meal-spike. Pre-loading with twice 60 additional grams of fast carbs based on previous experience. Coming from a frankly lo pre-meal of 55/70 mg/dl. Pre-training spike perfectly timed. IG collapse after 45 mins. BG after 25. Post training too high!

Lantus 14 - 7:15 PM     Novo 4 - 1:30 PM
Third case - standard meal, including 60/70 grs of carbs as rice. Lowered Novo to 3. Flattish high meal-spike (not good!). Still Pre-loading with 60 additional grams of fast carbs in prevision of a 1 hour training. Coming from a high pre-meal 140 mg/dl. Pre-training spike perfectly timed. Complete collapse after 35 mins. Post training OK
Lantus 15 - 7:15 PM     Novo 3 - 1:00 PM
 Fourth case - standard meal, including 60/70 grs of carbs as rice. Normal meal-spike. Pre-loading with 20 additional grams of fast carbs only based on the fast rising levels. Coming from a pre-meal of 110 mg/dl. Pre-training spike well timed. Complete collapse after 35 mins. Previous day lantus was advanced by 45 mins. Huge post-training spike. Probably attributable to the previously established 22 hours of Lantus activity. There's that two hours window where he apparently has no insulin left on board. Extremely tired and cramping a bit after the training. 2 units of Novo given as correction as soon as we got home.
Lantus missing 15 - 6:30 PM     Novo 4 - 1 PM
 Fifth case - earlier standard meal, including 60/70 grs of carbs as rice. Normal meal-spike, almost leading to a post-meal low. Pre-loading with 30 additional grams of fast carbs in prevision of a 1 hour training and 1 unit of Novo to prevent the previous lack of insulin. No collapse. Best performance during training. Still a post training rebound, at the limit of the acceptable.
Lantus 15 - 6:30 PM      Novo 5 - noon    Novo 1 3:00 PM

Conclusion - try to fine tune case 5. Advance pre-meal insulin by 15 mins to tame meal spike and post meal low? Try 2 additional units of insulin pre training with slower carbs? Well see...
