In contemporary sports nutrition there is also a second question: "can protein choices that support recovery and adaptation also be more sustainable?" This matters because diet is a major contributor to environmental impact. Estimates often place diet at roughly 20 to 30 percent of annual greenhouse gas emissions, with...]]></description><link>https://www.mysportscience.com/post/protein-sources-for-athletes-animal-plant-and-alternative-proteins</link><guid isPermaLink="false">6a4ce21c543b72560a3d8bac</guid><category><![CDATA[Blog]]></category><category><![CDATA[Protein ]]></category><category><![CDATA[Recovery]]></category><category><![CDATA[Supplements]]></category><pubDate>Thu, 16 Jul 2026 09:07:52 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/a04440_de00151cae65416990d89fd0abe9d1d3~mv2.png/v1/fit/w_1000,h_832,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Oliver Witard</dc:creator></item><item><title><![CDATA[How much protein do athletes really need?]]></title><description><![CDATA[Is more protein better for muscle building?

It became the villain of high-intensity exercise. Coaches blamed it for fatigue. Athletes blamed it for the burning sensation in their legs.

That narrative was outdated 30 years ago but it still persists in places and is still passionately pursued by some coaches today.

During the 1990s the message appeared simple and compelling: consume carbohydrate immediately after exercise, ingest protein within 30 minutes, and avoid missing the critical recovery window. Over time these ideas became embedded in sports practice. Athletes built routines around them and many still worry that delaying a recovery drink by an hour may compromise...]]></description><link>https://www.mysportscience.com/post/nutrient-timing-does-the-window-of-opportunity-really-exist</link><guid isPermaLink="false">6a22c3ff367ed35011d818cf</guid><category><![CDATA[Blog]]></category><category><![CDATA[Recovery]]></category><category><![CDATA[Carbohydrate]]></category><category><![CDATA[Protein ]]></category><pubDate>Fri, 05 Jun 2026 14:17:09 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/4515cc_1d22539196e84d1385060b2adfa95dc2~mv2.jpg/v1/fit/w_1000,h_671,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Asker Jeukendrup</dc:creator></item><item><title><![CDATA[Allostasis in sport ]]></title><description><![CDATA[If you have spent any time in elite sport, you will have met the athlete whose decline does not fit a neat narrative.

Increase load (sensibly) and you adapt. Increase it too fast, too far, or for too long, and fatigue rises, illness risk creeps in, and performance stalls or drops. Entire monitoring systems, dashboards, and coaching conversations are built around that logic.
