Should resistance training programs aimed at muscular hypertrophy be periodized? A systematic review of periodized versus non-periodized approaches
Conclusion Based on the results of our review, we conclude that similar hypertrophic effects may be achieved using either a PER or a NP approach. Importantly, the findings are specific to short-term training interventions, as the average duration of programs across studies amounted to ∼15weeks; and to untrained individuals, as only two studies involved resistance-trained participants. A limitation of the reviewed literature also pertains to the small number of studies (n =3) using direct measures of hypertrophy (i.e., magnetic resonance imaging or ultrasound). Further research is needed to fill in the gaps in the curre...

Influence d ’une basse pression des pneumatiques sur les performances chronométrées chez des handibasketteurs
Conclusion The rolling distances in the deceleration test were less with 5bar. Low pressure decreases sprint performance in straight line. The rolling resistances could explain these results. The slides observed on the parquet with 9bar do not allow to confirm the results of the sprint. Low reliability measured by Étoile test would be related to variations in different displacements, such as stops and half-turns. The prospects would be to confirm on a synthetic floor and with other disciplines as wheelchair rugby or tennis. (Source: Science and Sports)
