This is me on the way back from pool after swimming. This is me, Lena, after the usual 1.5K  swim.

I've been swimming in an open pool for many weeks now, almost every day, almost the same distance - 1.5 kilometers.

My watch with 33 rounds (25 yards x 66)

Swimming in UCSD pool, I started to count laps like in running, by rounds, to make it easier. So now, I touch the lap button on my watch on the start point only. I mostly swim a mile or so, in breaststroke, almost daily. Today I made 33 rounds (50 yards or 45.7 meters each, 25-yard laps x 66). It is 1650 yards, or ~ 0.94 miles, or ~1509 kilometers. 

My times stopped improving: the time for 1.5K on the watch is one of my best times - 41 minutes and 14 seconds, often I am 1-2 minutes slower.

My watch after swimming 1.5K in 40:42 (25 yards x 66)

Happy about my first time swimming 1500 meters in under 41 minutes! Today I got to swim very late because of traffic and waiting in a post office (no Sunshine for my new sundress), but I was faster than yesterday by 1 minute: 1.5K in around 40:42 minutes vs 41:59. Not so tempted to switch from breaststroke to freestyle anymore. 

UCSD Pool

After yesterday's 45 minutes swim in the cold and seaweedy Pacific ocean, in a restrictive wet suit, today's flat blue water surface seemed unreal.

I made 2 swimmer's miles (132 x 25 yards) or 3000 m in over 86 minutes. The day before yesterday I made only one, but in 42 minutes, the fastest by now.

This sunny afternoon was peaceful - wish you many of these.

UCSD open air pool, 1.5K

Suddenly, my time on one swimmer's mile (66 short laps/lengths of this open air pool) has improved by 3 minutes! After making that 6 km swim I went back to 1.5 km a day to the same time as before: around 45 minutes, and today it was under 42!

Additionally, for the first time I made a couple of lengths (25 yards) in 34 seconds, my best time before was 36. Additionally, I had several 35-s in a row. 

No idea why. I did not sleep well for two last nights because of the troubles in my private life, and the last night I slept on a rather soft surface, not on my usual double yoga mat, and my back was aching.

On the other hand, my style gets better, effortlessly (still breaststroke).

6K Pool Swim

I did not want to stop swimming, and wanted to check whether I could double my usual these days distance. I did not care much about the style and speed, I just wanted to move forward in water, because nothing better waited for me outside on this emotionally excruciating day.

264 length (25 yards), 6 km total, in almost 3:07 (187 minutes). Six kilometers should constitute 4 swimmer's miles. First 200 I made in 2:20, first 5 km - in 2:35 (155 minutes).

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:

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.
