A Systematic Review of the Efficacy of Contingency Management for Substance Use Disorders in Low and Middle Income Countries.

Background: The impact of illicit substance use is especially devastating in low-resourced countries where factors such as poverty, unemployment, and inadequate services impede successful treatment. Contingency management (CM) is a treatment for substance use disorders that has shown to be effective in eliciting behaviour change. The efficacy of CM interventions in low and middle income countries (LMICs) has been under explored.

Acute Effects of Ballistic and Non-ballistic Bench Press on Plyometric Push-up Performance.

The purpose of this study was to examine the effects of a ballistic or non-ballistic concentric-only bench press (COBP) on subsequent plyometric push-up performance. Fourteen resistance trained men completed two separate one-repetition-maximum (1RM) testing sessions followed by three randomized experimental explosive push-up sessions. These sessions combined a heavy concentric bench press with plyometric push-ups.
