# Alpha memo: effect timing protein supplement context boundary

**One-sentence alpha:** Effect of carbohydrate-protein supplement timing on acute exercise-induced muscle damage made us expect supplement would travel cleanly as a positive signal; Effect of timing of whey protein supplement on muscle damage markers after eccentric exercise forces the update that the same anchor can fail, reverse, or split by context.

**Receipt 1:** Effect of timing of whey protein supplement on muscle damage markers after eccentric exercise | 2017 | 10.12965/jer.1735034.517 | finding: 1. J Exerc Rehabil. 2017 Aug 29;13(4):436-440. doi: 10.12965/jer.1735034.517. eCollection 2017 Aug. Effect of timing of whey protein supplement on muscle damage markers after eccentric exercise. Kim J(1), Lee C(1), Lee J(1). Author information: (1)Sport, Health and Rehabilitation Major, College of Physical Education, Kookmin University, Seoul, Korea. Whey protein is a nutritional supplement commonly ingested for recovery following exercise. However, the timing when whey protein supplement must be ingested after muscle-damaging exercise is debatable. Therefore, the present study investigated the effects of the timing of supplement ingestion on muscle damage markers after eccentric or muscle-d

**Receipt 2:** Effect of carbohydrate-protein supplement timing on acute exercise-induced muscle damage | 2008 | 10.1186/1550-2783-5-5 | finding: 1. J Int Soc Sports Nutr. 2008 Feb 19;5:5. doi: 10.1186/1550-2783-5-5. Effect of carbohydrate-protein supplement timing on acute exercise-induced muscle damage. White JP(1), Wilson JM, Austin KG, Greer BK, St John N, Panton LB. Author information: (1)Department of Exercise Science, University of South Carolina Columbia, SC 29101, USA. whitejp@mailbox.sc.edu. PURPOSE: To determine if timing of a supplement would have an effect on muscle damage, function and soreness. METHODS: Twenty-seven untrained men (21 +/- 3 yrs) were given a supplement before or after exercise. Subjects were randomly assigned to a pre exercise (n = 9), received carbohydrate/protein drink before exercise and placebo after

**Why this is surprising:** The pair has `promise_reversal` geometry over `timing, protein, supplement` rather than a broad literature-summary bridge.

**Search receipt:** hits=20; shards=1525/1525; sources=biorxiv,openalex,pubmed,semantic_scholar,semantic_scholar_abstracts; papers_searched=1456919317; partial=False.

**Caveats/falsifiers:**
- Reject if the shared anchor is not the same construct/intervention in the full text.
- Reject if later receipts show the apparent reversal is only population, dose, or measurement noise.
- Reject if either receipt is a review, case-only report, or keyword-only match.
