Malta ES et al. · 2021Sports MedicineSystematic review with meta-analysis of 8 controlled studies asking whether the *regular* use of post-training cold water immersion (≤15 °C) changes the adaptations produced by a structured training programme, compared with passive recovery. Strength adaptations were impaired: pooled across 1RM, isometric strength and strength endurance the effect was SMD = −0.60 (95% CI −0.87 to −0.33, p < 0.0001), and for ballistic performance SMD = −0.61 (95% CI −1.11 to −0.11, p = 0.02). Endurance adaptations were untouched: maximal aerobic power and time-trial mean power gave SMD = −0.07 (95% CI −0.54 to 0.53, p = 0.71) and time-trial duration SMD = 0.00 (95% CI −0.58 to 0.58, p = 1.00). The interference with training adaptation therefore appears specific to strength/hypertrophy, not to aerobic fitness.

Roberts LA et al. · 2015Journal of PhysiologyThe landmark trial. In the long-term arm, 21 physically active men trained twice weekly for 12 weeks and, after every session, did either 10 min of cold water immersion (10.1 ± 0.3 °C) or 10 min of active recovery (low-intensity cycling). Gains were markedly smaller with CWI: quadriceps lean mass +103 ± 71 g vs +309 ± 73 g (P < 0.001), leg-press 1RM +133 ± 43 kg vs +201 ± 65 kg (P = 0.033), knee-extension 1RM +17.8 ± 9.2 kg vs +33.8 ± 8.5 kg (P < 0.001); type II fibre cross-sectional area (+17%) and myonuclei per fibre (+26%) rose only in the active-recovery group. A separate acute arm showed why: CWI blunted or delayed the post-exercise rise in satellite cells (NCAM+ 10–30%, Pax7+ 20–50% at 24–48 h) and the phosphorylation of p70S6 kinase in the mTOR pathway.

Cold water immersion reduced DOMS at 24 h, 48 h and 96 h post-exercise compared with passive recovery
Meta-analysis of 14 studies found CWI was effective at reducing DOMS at 24h, 48h, and 96h post-exercise compared to passive recovery.
Weighted 0.65 — Reported as 14 studies, but the article is closed-access with no abstract indexed, and no pooled participant total could be verified from any primary source -- so sample_size is omitted, and even the study count is unconfirmed against the article itself. Funding and competing interests are both explicitly declared none. Cold-water-immersion trials are inherently unblindable and rest on subjective soreness ratings, which systematically inflates apparent benefit; DOMS is also a symptom endpoint, not a recovery-of-function or performance endpoint.

regular cold water immersion impaired strength adaptations (SMD -0.60, 95% CI -0.87 to -0.33) and ballistic performance (SMD -0.61); endurance adaptations were unaffected (aerobic power SMD -0.07; time-trial duration SMD 0.00)
Systematic review with meta-analysis of 8 controlled studies asking whether the regular use of post-training cold water immersion (≤15 °C) changes the adaptations produced by a structured training programme, compared with passive recovery. Strength adaptations were impaired: pooled across 1RM, isometric strength and strength endurance the effect was SMD = −0.60 (95% CI −0.87 to −0.33, p < 0.0001), and for ballistic performance SMD = −0.61 (95% CI −1.11 to −0.11, p = 0.02).

The interference with training adaptation therefore appears specific to strength/hypertrophy, not to aerobic fitness.
Weighted 0.65 — k=8 controlled studies. The paper does not state a pooled participant total and the full text is paywalled, so sample_size is omitted rather than guessed. Only eight studies underpin the strength-versus-endurance dissociation, which is a thin base for a strong claim — though the review was PROSPERO-registered (CRD42018098898), used the Cochrane risk-of-bias framework, and is publicly funded with no declared conflicts.

Quadriceps lean mass +103 g with cold water immersion vs +309 g with active recovery (P < 0.001); leg-press 1RM +133 vs +201 kg; type II fibre CSA (+17%) and myonuclei per fibre (+26%) rose only without CWI
The landmark trial. In the long-term arm, 21 physically active men trained twice weekly for 12 weeks and, after every session, did either 10 min of cold water immersion (10.1 ± 0.3 °C) or 10 min of active recovery (low-intensity cycling).

Weighted 0.65 — n=21 analysed (11 CWI vs 10 active recovery) of 24 enrolled, 12 weeks, single site. Small per-arm n and no participant blinding (impossible for cold water immersion), but randomised, independently funded, with muscle biopsies and a mechanistic acute arm (n=9) that explains the direction. Precise and internally consistent for its size; the modest n is the main limit.
