Today in the pool I repeated yesterday, made 132 of 25 yards (3K or 3 km) in 1:29 (89 minutes vs 91 last time), then swam till 148 (3.7K). Started with most lengths in 36 seconds, in 50s went down to 38-39, by the end I was already over 40.

Yesterday I read more tips for better Breaststroke, and today I tried a few things:

  • not to bring my hands behind my shoulders - finished the arm round faster,
  • to round my shoulders a bit by going out of the water - this I tried somewhere in 70s (laps) and it took me awhile to synchronize by body properly with this newly introduced movement, the problem was also that my body went higher out of the water than normally, and then sunk lower, which brought my lower body and legs to high up and I felt even touching the water surface with my feet: it made their puch less powerful,
  • then I started looking down to measure the sliding speed after the leg move to find the optimal time point to end gliding and take a breath, sometimes I went out a moment earlier, sometimes later, and measured the lap speed, and found out that I did not slide long enough before,
  • so I figured the better rhythm for myself, and it happened to be 4/4:
    1 - inhale with arm stroke, 2 - leg stroke, 3-4 - gliding, and this division is not quite right, but the counting was helpful.
    • "One, two, three, four."
    • "Eins, Zwei, Drei, Vier".
    • "Раз, два, три, четыре".
    • - I could not decide, which language was better :)

Bringing my head down to see the bottom of the pool with its tiles straight created a problem of grasping water with my nose sometimes, because I could not coordinate changing the angle of my head moving out of the water perfectly, and not only at first, but several times randomly till the end.

But I am happy with the 2 minutes gain and hope to have even more fun tomorrow, because I bought a tighter silicon swim cup because my long hair was all over the place, slapping around on turns and covering my goggles on the way out, and on long swims it is annoying.

Ah yes, I needed to stop twice for 20-30 seconds: to rinse the glasses and to adjust the watch.

Wish you to move forward without interruptions!

Protein Digestibility-Corrected Amino Acid Score

The protein digestibility-corrected amino acid score (PDCAAS) has been adopted by FAO/WHO as the preferred method for the measurement of the protein value in human nutrition. 

PDCAAS = Amino Acid Score x Digestibility

The method is based on comparison of the concentration of the first limiting essential amino acid in the test protein with the concentration of that amino acid in a reference (scoring) pattern. This scoring pattern is derived from the essential amino acid requirements of the preschool-age child.

Although the principle of the PDCAAS method has been widely accepted, critical questions have been raised in the scientific community:

  1. the validity of the preschool-age child amino acid requirement values (more than 4 times greater than the EAA requirement for an adult),
  2. the validity of correction for fecal instead of ileal digestibility,
  3. the truncation of PDCAAS values to 100%.

The reference scoring pattern was based on studies performed more than 25 years ago on a limited number of 2-year-old children recovering from malnutrition.

According to the current official recommendations, a 2-year old child needs ~ 3x higher essential-to-non-essential amino acid ratio, and needs essential amino acids in different proportions than adult. Methionine/cysteine is the limiting essential amino acids for adults, and for children it is lysine or tryptophan.

The use of fecal digestibility overestimates the nutritional value of a protein because amino acid nitrogen entering the colon is lost for protein synthesis in the body and is, at least in part, excreted in urine as ammonia.
