Kinetic Analysis, Potentiation, and Fatigue During Vertical and Horizontal Plyometric Training: An In-Depth Investigation Into Session Volume.

Unlabelled: Despite previous support for plyometric training, optimal dosing strategies remain unclear.

Purpose: To investigate vertical and horizontal jump kinetic performance following a low-volume plyometric stimulus with progressively increased session jump volume.

Methods: Sixteen academy rugby players (20.

The Effect of Low-Volume Preseason Plyometric Training on Force-Velocity Profiles in Semiprofessional Rugby Union Players.

Watkins, CM, Gill, ND, Maunder, E, Downes, P, Young, JD, McGuigan, MR, and Storey, AG. The effect of low-volume preseason plyometric training on force-velocity profiles in semiprofessional rugby union players. J Strength Cond Res 35(3): 604-615, 2021-Rugby union is a physically demanding and complex team sport requiring athletes across all positions to express speed and acceleration.

Electrostimulation's enhancement of recovery during a rugby preseason.

Unlabelled: Rugby preseason training involves high-volume strength and conditioning training, necessitating effective management of the recovery-stress state to avoid overtraining and maximize adaptive gains.

Purpose: Compression garments and an electrostimulation device have been proposed to improve recovery by increasing venous blood flow. These devices were assessed using salivary testosterone and cortisol, plasma creatine kinase, and player questionnaires to determine sleep quality, energy level, mood, and enthusiasm.

Cross-cultural structures of concentric and diametric dualism in Lévi-Strauss' structural anthropology: structures of relation underlying the self and ego relation?

The parallels between Jung's and Lévi-Strauss' concentric cross-cultural structures of the unconscious are highlighted. Lévi-Strauss' basic contrasts between concentric and diametric dualisms are developed into psychologically relevant differences regarding symmetry, connection and separation, and interaction between foreground and background structures respectively. These contrasts between concentric and diametric structures are applied as a common structural framework for understanding Jungian conceptions of the self, the ego and their relations, Freudian views of compensation and repetition in obsessional neurosis, and Winnicott's conception of a child's transitional object.
