Ischemic preconditioning: what else can it do…?

Ischemic preconditioning (IPC) can enhance maximal strength likely due to neural priming. Cruz et al. (Cruz R, Tramontin AF, Oliveira AS, Caputo F, Denadai BS, Greco CC.

Can the cross-education of strength attenuate the impact of detraining after a period of strength training? A quasi-randomized trial.

Purpose: Unilateral strength training may attenuate the decline in muscle strength and size in homologous, contralateral muscles. This study aimed to determine whether the cross-education of strength could specifically attenuate the effects of detraining immediately after a short (prehabilitation-type) period of strength training.

Methods: Twenty-six strength-trained participants were assigned to either four weeks of unilateral strength training of the stronger arm (UNI) or detraining (Detrain).

pQCT- and Ultrasound-based Muscle and Fat Estimate Errors after Resistance Exercise.

Purpose: Resistance exercise increases blood flow, induces osmotic and hydrostatic fluid shifts during and immediately after exercise, and may trigger inflammatory responses for several days in the working muscle. The resultant muscle swelling can subsequently affect muscle size and quality assessments. However, the effects of muscle swelling on x-ray attenuation of adipose estimate errors are unknown.

Neural conduction and excitability following a simple warm up.

Objective: This study examined the effect of a generic, active warm up on neural and muscular conduction time.

Design: Single group, pre-post design.

Methods: Central and peripheral neuromuscular conduction time was quantified in the abductor pollicis brevis (APB) and gastrocnemius muscles of 18 healthy participants (mean age 25.
