The present study aimed to determine whether whole-body fat oxidation and muscle deoxygenation kinetics parameters during exercise were related in individuals with different aerobic fitness levels.Methods: Eleven cyclists [peak oxygen uptake (V.O2peak): 64.9 ± 3.9 mL⋅kg–1⋅min–1] and 11 active individuals (V.O2peak: 49.1 ± 7.4 mL⋅kg–1⋅min–1) performed a maximal incremental...

Countermovement jump training is more effective than drop jump training in enhancing jump height in non-professional female volleyball players

Ruffieux, Jan ; Wälchli, Michael ; Kim, Kyung-Min ; Taube, Wolfgang

In: Frontiers in Physiology, 2020, vol. 11, p. -

The aim of the present study was to compare the effects of countermovement jump (CMJ) and drop jump (DJ) training on the volleyball-specific jumping ability of non-professional female volleyball players. For that purpose, 26 female volleyball players (15–32 years) were assigned to either a CMJ (20.4 ± 3.1 years, 171.0 ± 3.0 cm) or a DJ training group (22.0 ± 4.4 years, 168.2 ± 5.0 cm), ...

Minimal pseudo-Anosov stretch factors on nonoriented surfaces

Liechti, Livio ; Strenner, Balázs

In: Algebraic & Geometric Topology, 2020, vol. 20, no. 1, p. 451–485

We determine the smallest stretch factor among pseudo-Anosov maps with an orientable invariant foliation on the closed nonorientable surfaces of genus 4, 5, 6, 7, 8, 10, 12, 14, 16, 18 and 20. We also determine the smallest stretch factor of an orientation-reversing pseudo-Anosov map with orientable invariant foliations on the closed orientable surfaces of genus 1, 3, 5, 7, 9 and 11. As a ...
