Block periodization training in Navy Seal Operators: effect of 12 weeks on salivary hormones
Abstract
We sought to determine the stress response to block periodization training (BPT) in Navy SEAL Operators by measuring salivary hormones over a 12 week period. Eighteen Navy SEAL Operators (31 ± 6 yrs, 86.6 ± 9.0 kg, 176.2 ± 5.9 cm, 17.5 ± 6.5% fat) participated in a 12 week BPT during routine operational training. Salivary free testosterone (FT), dehydroepiandrosterone sulfate (DHEAS), and cortisol (C) were obtained at four time points separated by 4 weeks coincident with changes in rest:work ratio: 1‐ prior to training (T1),2‐ moderate rest:moderate intensity (T2), 3‐ short rest:moderate intensity (T3), 4‐ long rest:high intensity (T4). The ratios of FT:C and DHEAS:C were also calculated. A significant increase in FT was observed at T3 (20.3 ± 31.4%; p Supported by ONR #N00014–11‐1–0929.
