Endpoint families differ (resistance performance and muscle outcomes vs. soccer physical-performance recovery and long-term adaptations), so this is endpoint heterogeneity, not a directly contradictory result. Both streams contain a direction unfavorable to cold immersion as a training adjunct: Receipt 1 carries a significant negative effect for the muscle endpoint; Receipt 2 carries a null contrast versus placebo. Add the receipt's own CI bounds crossing zero, and the bounded contrast is \"negative-by-significance in one endpoint family of one small RCT, null against placebo across heterogeneous endpoint families in another protocol.\" Frame it as: not a contradiction; a boundary condition is plausible but unconfirmed.","If subsequent evidence confirms that the negative muscle-direction signal in Receipt 1 is real and extends beyond one small RCT to broader resistance-trained populations, then regular cold immersion could quietly blunt muscle adaptation while leaving wider performance metrics statistically flat, undermining the rationale for routine post-training cold immersion. Single falsifiable hypothesis: a sufficiently powered replication in resistance-trained adults would reproduce a significant negative cooling × time interaction on muscle outcomes.","10.1123/ijspp.2019-0965 - role=negative_signal; design=randomized_trial; population=human; outcome=performance; direction=negative; support=direct/high.
