Acute Soy Supplementation Improves 20-km Time Trial Performance, Power, and Speed
INTRODUCTIONIsoflavones, a chemical class of phytoestrogens found in soybeans and soy products, may have biological functions similar to estradiol.

PURPOSETo determine if acute fermented soy extract supplementation influences 20-km time trial cycling performance and cardiac hemodynamics compared with a placebo.
METHODSSubjects included 25 cyclists and triathletes (31 ± 8 yr, V˙O2peak55.1 ± 8.4 mL·kg·min). Each subject completed a V˙O2peak assessment, familiarization, and two 20-km time trials in randomized order after ingestion of a fermented soy extract supplement or placebo. The fermented soy extract consisted of 30 g powdered supplement in 16 fl. ounces of water. The placebo contained the same quantities of organic cocoa powder and water. Each trial consisted of 60 min of rest, 30 min at 55% Wpeak, and a self-paced 20-km time trial.
RESULTSSoy supplementation elicited a faster time to 20-km completion (−0.22 ± 0.51 min; −13 s), lower average HR (−5 ± 7 bpm), and significantly greater power (7 ± 3 W) and speed (0.42 ± 0.16 km·h) during the last 5 km of the time trial compared with placebo. Analysis of the results by relative fitness level ( |

Analysis of the results by relative fitness level (<57 vs ≥ 57 mL⋅kg⋅min) indicated that those with a higher level of fitness reaped the largest performance improvement alongside a reduced HR (−5 ± 7 bpm).
CONCLUSIONSIngestion of a fermented soy extract supplement improved sprint-distance performance through improvements in both power and speed. For those with great aerobic fitness, soy supplementation may help to decrease cardiac demand alongside performance improvement.</description><identifier>ISSN: 0195-9131</identifier><identifier>EISSN: 1530-0315</identifier><identifier>DOI: 10.1249/MSS.0000000000002102</identifier><identifier>PMID: 31343517</identifier><language>eng</language><publisher>United States: Lippincott Williams & Wilkins</publisher><subject>Adult ; Athletic Performance - physiology ; Bicycling - physiology ; Cardiac Output - physiology ; Dietary Supplements ; Double-Blind Method ; Endothelium, Vascular - enzymology ; Glycine max - chemistry ; Heart Rate - physiology ; Humans ; Isoflavones - administration & dosage ; Male ; Nitric Oxide Synthase - metabolism ; Plant Extracts - administration & dosage ; Stroke Volume - physiology ; Young Adult</subject><ispartof>Medicine and science in sports and exercise, 2020-01, Vol.52 (1), p.170-177</ispartof><rights>Lippincott Williams & Wilkins</rights><rights>2020 American College of Sports Medicine</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c4802-ee96ea5ffe0558749a4cea2f74a19630e70540a1287bc0bb4000bcbbf5fe44d23</citedby><cites>FETCH-LOGICAL-c4802-ee96ea5ffe0558749a4cea2f74a19630e70540a1287bc0bb4000bcbbf5fe44d23</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf><![CDATA[$$Uhttp://ovidsp.ovid.com/ovidweb.cgi?T=JS&CSC=Y&NEWS=N&PAGE=fulltext&PDF=y&D=ovft&AN=00005768-202001000-00019$$EPDF$$P50$$Gwolterskluwer$$H]]></linktopdf><linktohtml>$$Uhttp://ovidsp.ovid.com/ovidweb.cgi?T=JS&NEWS=n&CSC=Y&PAGE=fulltext&D=ovft&AN=00005768-202001000-00019$$EHTML$$P50$$Gwolterskluwer$$H</linktohtml><link.rule.ids>314,780,784,4609,27924,27925,64666,65461</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/31343517$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>SEELEY, AFTON D.</creatorcontrib><creatorcontrib>JACOBS, KEVIN A.</creatorcontrib><creatorcontrib>SIGNORILE, JOSEPH F.</creatorcontrib><title>Acute Soy Supplementation Improves 20-km Time Trial Performance, Power, and Speed</title><title>Medicine and science in sports and exercise</title><addtitle>Med Sci Sports Exerc</addtitle><description>INTRODUCTIONIsoflavones, a chemical class of phytoestrogens found in soybeans and soy products, may have biological functions similar to estradiol.
