Running Economy While Running In Shoes Categorized As Maximal Cushioning, Miles A. Mercer, Tori M. Stone, John C. Young, John A. Mercer
International Journal of Exercise Science
International Journal of Exercise Science 11(2): 1031-1040, 2018. The purpose of the study was to determine if running economy was influenced by wearing maximal cushioning shoes vs. control (neutral cushioning) shoes. Participants (n=10, age=28.2±6.1yrs; mass=68.1±10.2 kg; height=170±6.1 cm) completed two experiments. Each experiment included running conditions wearing control and maximal cushioning shoes. In Experiment 1, participants ran on a treadmill at three speeds in each shoe condition (6 total conditions). The speeds were: 1) preferred speed, 2) preferred speed + 0.447 m·s-1, and 3) preferred speed - 0.447 m·s-1. In Experiment 2, participants ran on a …

Effects Of Strength Training Sessions Performed With Different Exercise Orders And Intervals On Blood Pressure And Heart Rate Variability, Sandro Lemos, Tiago Figueiredo, Silvio Marques, Thalita Leite, Diogo Cardozo, Jeffrey Willardson, Roberto Simão
International Journal of Exercise Science
International Journal of Exercise Science 11(2): 55-67, 2018. This study compared the effect of a strength training session performed at different exercise orders and rest intervals on blood pressure and heart rate variability (HRV). Fifteen trained men performed different upper body exercise sequences [large to small muscle mass (SEQA) and small to large muscle mass (SEQB)] in randomized order with rest intervals between sets and exercises of 40 or 90 seconds. Fifteen repetition maximum loads were tested to control the training intensity and the total volume load. The results showed, significant reductions for systolic blood pressure (SBP) for all sequences …

Serum Tumor Necrosis Factor-Alpha Associates With Myocardial Oxygen Demand And Exercise Tolerance In Postmenopausal Women, Stephen J. Carter, David R. Bryan, William H. Neumeier, Stephen P. Glasser, Gary R. Hunter
International Journal of Exercise Science
International Journal of Exercise Science 11(2): 42-54, 2018. The functional implications of serum tumor necrosis factor-alpha (TNF-a), a marker of oxidative stress, on hemodynamic parameters at rest and during physical exertion are unclear. The aims of this investigation were to examine the independent associations of TNF-a on myocardial oxygen demand at rest and during submaximal exercise, while also evaluating the association of TNF-a on exercise tolerance. Forty, postmenopausal women, provided blood samples and completed a modified-Balke protocol to measure maximal oxygen uptake (VO2max). Large artery compliance was measured by pulse contour analyses while rate-pressure product (RPP), an index …

Acute Cardiovascular Responses After A Single Bout Blood Flow Restriction Training, Moisés Picón Martínez, Iván Chulvi Medrano, Juan Manuel Cortell Tormo, Juan Tortosa, Yasser Alkhadar, José Sanchís, Gilberto Laurentino
International Journal of Exercise Science
International Journal of Exercise Science 11(2): 20-31, 2018. Different types of exercise might produce reductions in blood pressure (BP). One physiological mechanism that could explain the lowering adaptation effect on BP after an exercise program is an improved in baroreflex control of muscle sympathetic nerve activity. Consequently, exploring the different methods of training and their post-exercise hypotension (PEH) becomes of interest for healthcare providers. Recently, it has been suggested that blood flow restriction training (BFR) can generate PEH. The aim of this study was to determine the acute response on cardiovascular variables after low intensity resistance training with BFR in …
