Identification Of High Responders For Interleukin-6 And Creatine Kinase Following Acute Eccentric Resistance Exercise In Elderly Obese Women, Vitor Tajra, Ramires Alsamir Tibana, Denis Cesar Leite Vieira, Darlan Lopes De Farias, Tatiane Gomes Teixeira, Silvana Schwerz Funghetto, Alessandro Oliviera Silva, Nuno Manuel Frade De Sousa, Jeffrey Willardson, Margo Gomes Oliviera Karnikowski, Jonato Prestes

Faculty Research and Creative Activity

Resistance exercise is used as a non-pharmacological tool to elicit both gains in and maintenance of physical function in the elderly. Thus, the present study examined the acute response of creatine kinase and interleukin-6 following an eccentric resistance exercise session in elderly obese women classified as high responders or normal responders.

Effects Of Different Rest Intervals Between Antagonist Paired Sets On Repetition Performance And Muscle Activation, Mariana F. Maia, Jeffrey M. Willardson, Gabriel A. Paz, Humberto Miranda

Faculty Research and Creative Activity

Effects

of different rest intervals between antagonist paired sets on

repetition performance and muscle activation. J Strength

Cond Res 28(9): 2529–2535, 2014—Recent evidence

suggests that exercising the antagonist musculature acutely

enhances subsequent performance for the agonist musculature.

The purpose of this study was to examine the effects of

different rest intervals between sets for exercises that involve

antagonistic muscle groups, a technique referred to as

antagonist paired sets (APS). Fifteen recreationally trained

men were tested for knee extension (KE) exercise performance,

with or without previous knee flexion (KF) exercise

for the antagonist musculature. The following protocols were

performed in random …

Acute Effect Of Caffeine Intake On Hemodynamics After Resistance Exercise In Young Non-Hypertensive Subjects, Diego Souza, Juliano Cosanatto, Roberto Poton, Jeffrey Willardson, Marcos Polito

Faculty Research and Creative Activity

This study aimed to examine the effect of caffeine on hemodynamics after a resistance exercise session. Fifteen subjects completed two randomly ordered experimental resistance exercise sessions 45 min after the ingestion of either caffeine (4 mg.kg-1) or placebo. Systolic (SBP), diastolic (DBP) and mean (MAP) blood pressures were measured before consuming caffeine; SBP, DBP, MAP, heart rate, stroke volume, cardiac output and peripheral vascular resistance (PVR) were measured immediately before and after each of the sessions; SBP, DBP and MAP were measured for 9 hours after sessions. Caffeine increased (p < 0.05) pre-exercise DBP and MAP. In caffeine and placebo conditions significant decreases (p < 0.05) were noted in SBP, MAP, and PVR between the pre- and post-exercise time points. Notwithstanding, the mean values for SBP, DBP and MAP during the 9 h of post-exercise monitoring were increased (p < 0.05) for the caffeine. In conclusion, the cardiovascular effects of caffeine are different over the post-exercise period after resistance exercise in normotensive young adults.
