How to train in heat and humidity Athletes competing and training in hot, humid climates are faced with a different set of challenges, and with a warming climate, experts say learning to adapt is key.

Abstract During pregnancy an increased cardiac output ( ̇Q) and blood volume (BV) occur to support fetal growth. Increased ̇Q and BV also occur during chronic endurance exercise training and benefit performance. We investigated if sprint interval training (SIT) undertaken early postpartum maintains the elevated ̇Q and BV of pregnancy and benefits performance. The participant, a competitive field hockey player and former cyclist, visited our laboratory at 2 weeks of gestation (baseline) and postpartum pre-, mid- and post-intervention (PP pre , PP mid and PP post ). Delivery was uncomplicated and she felt ready to start the SIT programme 5 weeks postpartum. Inert gas rebreathing was used to measure peak exercise ̇Q ( ̇Q peak ); ̇V O 2 peak was measured with a metabolic cart; and postpartum haematological values were measured with carbon monoxide rebreathing. The 18 SIT sessions progressed from four to eight sprints at 130% of ̇V O 2 peak peak power output. ̇Q peak increased from baseline at all postpartum time points (baseline 16.2 vs. 17.5, 16.8 and 17.2 L/min at PP pre , PP mid and PP post , respectively). Relative ̇V O 2 peak remained below baseline values at all postpartum measurements (baseline 44.9 vs. 41.0, 42.3 and 42.5 mL/kg/min at PP pre , PP mid and PP post , respectively) whereas absolute ̇V O 2 peak rapidly reached baseline values postpartum (baseline 3.19 vs. 3.12, 3.23 and 3.18 L/min at PP pre , PP mid and PP post , respectively). Postpartum BV (5257, 4271 and 5214 mL at PP pre , PP mid and PP post , respectively) and Hb mass (654, 525 and 641 g at PP pre , PP mid and PP post , respectively) were similar between PP pre and PP post but decreased alongside ̇Q peak at PP mid . Peak power was returned to pre-pregnancy values by intervention end (302 vs. 303W, baseline vs. PP post ). These findings show that SIT undertaken early postpartum defends the elevated ̇Q peak of pregnancy and rapidly returns absolute ̇V O 2 peak and peak power to baseline levels.

We heard from our colleague Normand today about his work with elite female athletes returning to training after pregnancy. Sprint interval training on Zwift 3/wk starting 5wks postpartum returns abs VO2peak & Wpeak within 6wks. More research coming on post-pregnancy return to sport! #SportScience
