In a propensity score-matched analysis of 77 CPTA patients with sufficient follow-up versus controls, there was significantly less biochemical recurrence (BCR; p = 0.01). Our study indicates that CPTA use appears to accelerate time to UC in age- and performance status-matched men undergoing RARP without increased risk of BCR. To test the hypothesis that hypoxic re-exposure after return from natural altitude training is beneficial in retaining hematological and performance adaptations. Eighteen mixed martial art fighters completed a 3-weeks natural altitude training camp at 2418m. Afterwards, participants were randomly assigned to a living high-training low (12h/d at a simulated altitude of 2800m) group (LHTL, n = 9) or a living low-training low group (LLTL, n = 9) for a 3-week sea-level training period. At baseline and after return to sea level, hematological [hemoglobin mass (Hb ) on days 2, 6, 9, 12, 15 and 21] and performance (3000m time trial and maximal oxygen uptake on days 4, 6, 9, 15 and 21) markers were assessed. Mean Hb increased from baseline to day 2 (11.7 ± 0.9 vs. 12.4 ± 1.3g/kg; + 6.6 ± 7.5%; P < 0.05). While Hb remained elevated above baseline in LHTL (P < 0.001), it returned near baseline levels from day 9 in LLTL. Irrespective of groups, mean V̇O was only elevated above baseline at day 2 (+ 4.5 ± 0.8%) and day 9 (+ 3.8 ± 8.0%) (both P < 0.05). Compared to baseline, 3000m running time decreased at day 4 (-3.1 ± 3.3%; P < 0.05) and day 15 (-2.8 ± 2.3%; P < 0.05) only. Despite re-exposure to hypoxia allowing a recovery of the hypoxic stimulus to retain Hb gains from previous altitude sojourn, there is no performance advantage of this practice above sea level residence. Our results also give support to empirical observations describing alternance of periods of optimal and attenuated performance upon return to sea level. Despite re-exposure to h
