Pre-sarcopenia in patients undergoing hemodialysis: Prevalence and association with biochemical parameters.

Background & Aims: Albumin and C reactive protein (CRP) concentrations are associated with the loss of lean body mass in the elderly. However, it remains to be ascertained whether these parameters are associated with pre-sarcopenia of chronic renal failure adult's patients undergoing replacement therapy. Therefore, we aimed to investigate the prevalence of pre-sarcopenia and it association with serum albumin and CRP concentrations in adult patients.

Acute Caffeinated Coffee Consumption Does not Improve Time Trial Performance in an 800-m Run: A Randomized, Double-Blind, Crossover, Placebo-Controlled Study.

Introduction: Studies evaluating caffeinated coffee (CAF) can reveal ergogenic effects; however, studies on the effects of caffeinated coffee on running are scarce and controversial.

Aim: To investigate the effects of CAF consumption compared to decaffeinated coffee (DEC) consumption on time trial performances in an 800-m run in overnight-fasting runners.

Methods: A randomly counterbalanced, double-blind, crossover, placebo-controlled study was conducted with 12 healthy adult males with experience in amateur endurance running.
