High peak power gigahertz Yb:CALGO laser

Optics Express, 2014
We present a high-power gigahertz SESAM modelocked Yb:CALGO laser with sub-60-fs pulses. The laser delivers an average output power of 2.95 W at a pulse repetition rate of 1.8 GHz in fundamental modelocking without additional pulse compression or amplification.

Polarized training has greater impact on key endurance variables than threshold, high intensity or high volume training

Frontiers in Physiology, 2014
Endurance athletes integrate four conditioning concepts in their training programs: high-volume training (HVT), ‘threshold-training’ (THR), high-intensity interval training (HIIT) and a combination of these aforementioned concepts known as polarized ...

Effects of repeated sprint training with constant or incremental rest intervals on the decrement score, blood lactate concentration, and Wingate anaerobic test performance: a pilot study

Frontiers in Sports and Active Living
The effects of repeated sprint training with constant rest intervals (CRIs) vs. incremental rest intervals (IRIs), without matching the total rest duration, on muscle fatigue, glycolytic metabolism, and anaerobic work capacity remain unclear.
