I am reading a book by Jan Olbrecht, the Dutch physiologist. In the last chapter he talks about using a T-30 test in the abscence of blood lactate testing to determine a swimmers aerobic capacity. He then gives a table to assign a range of 100m</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: Can you convert metric times to yardage times?</title><link>https://community.usms.org/thread/77139?ContentTypeID=1</link><pubDate>Tue, 30 Oct 2007 12:54:03 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:c57765d6-3686-4a97-9e72-a4fa8fcb5c21</guid><dc:creator>knelson</dc:creator><description>Turns and SDK make a big difference.

Absolutely, but they are going to make a much bigger difference (percentage wise, anyway) in something like a 100 back than in a timed 30 minute swim.  For the purpose spudfin mentioned just multiplying the meter time by 0.9 should give something good to within a second or two per hundred and that should be sufficient.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Can you convert metric times to yardage times?</title><link>https://community.usms.org/thread/77104?ContentTypeID=1</link><pubDate>Tue, 30 Oct 2007 12:22:15 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:c57eb9eb-cea8-424b-83f0-7db1b51b5b2c</guid><dc:creator>ande</dc:creator><description>it is just math 
but other factors come into play like 
TURNS and SDKs

as an example here&amp;#39;s Neil Walker&amp;#39;s 
lifetime best times 

100 free&amp;#39;s
scy 42.35 
scm 46.88 
LCM 48.55 

100 back&amp;#39;s
scy 44.92
scm 50.75
LCM 54.58 

Now Compare the differences of the differences  
100 fr times vs his 100 bk times

100 fr LCM vs SCY
48.55 - 42.35 = 6.20   

100 bk LCM vs SCY 
54.58 - 44.92 = 9.66

100 fr LCM vs SCM
48.55 - 46.88 = 1.67   

100 bk LCM vs SCM
54.58 - 50.75 = 3.83

the difference is because of turns and SDK&amp;#39;s
Swimmers can SDK twice as far on 
SCY &amp;amp; SCM 100&amp;#39;s vs LCM 
Turns and SDK make a big difference. 


All you really need to know is 1 yard = 0.9144 meters.  Just multiply the meters time by .9144 and you&amp;#39;ll be close.  The only other factor is the number of turns.  Since you&amp;#39;ll do more turns in a T-30 swum in a 25 yard pool versus a 25 meter pool you should be slightly faster in the yards pool, assuming you have good turns.  Multiplying by 0.9 will get you pretty close I would guess.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Can you convert metric times to yardage times?</title><link>https://community.usms.org/thread/77170?ContentTypeID=1</link><pubDate>Tue, 30 Oct 2007 11:06:07 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:1234259f-c44c-402f-9efa-43d6a6246542</guid><dc:creator>Former Member</dc:creator><description>Thanks for all the responses.  I think I will use the down and dirty 0.9 multiplier as I am using it as a broad indicator for setting my intrinsice(fast) and extrinsic(Pace) workouts in prepping for longer open water swims.  I found it interesting all the commentary on flip turns and sdk as I am just incorporating both into my workouts this winter. All good stuff.   Great  forum. 
Thanks again.

This topic has been discussed several times here in the past.  I did a search on the word &amp;quot;conversion&amp;quot; and came up with a few threads.

The 4 I tried all gave the same number but the swimmingworld one gave a different number. Strange.
