Post‐Activation Potentiation: Is there an Optimal Training Volume and Intensity to Induce Improvements in Vertical Jump Ability in Highly‐Trained Subjects?

, 2009 ). Acute increases in performance can be substantially affected by the balance between PAP mechanisms and fatigue ( Chatzopoulos et al., 2007 ; Jones and Lees, 2003 ; Scott and Docherty, 2004 ; Young et al., 1998 ). These “opposing effects” have usually produced inconsistent findings and unclear training guidelines ( Lowery et al., 2012 ; Mola et al., 2014 ; Sale, 2002 ). Moreover, it appears that this balance may be altered by several factors, such as training experience, length of the rest period prior to subsequent exercise, and volume and intensity of

Player Load and Metabolic Power Dynamics as Load Quantifiers in Soccer

important aspects for fitness coaches to consider ( Eirale et al., 2013 ). Correct planning and monitoring of training demands is crucial to optimize performance of top‐level players (Gómez‐Díaz et al., 2013). The internal training load is the physical response to stress factors. Heart rate telemetry, oxygen consumption, rating of perceived exertion (RPE) or blood lactate are commonly used methods for assessing internal loads ( Borresen and Lambert, 2009 ). The external training load is the objective measurement of the work performed by the players, and is classified in

High Speed Running and Sprinting Profiles of Elite Soccer Players

Introduction Studies continue to investigate the physical and technical performances of elite soccer players during official games across congested periods ( Bradley et al., 2009 ; Rampinini et al., 2007 ; Rey et al., 2010 ) in accordance with positional roles ( Bradley et al., 2009 ; Di Salvo et al., 2007 ; Rampinini et al., 2007 ) or depending on the match conditions. In particular, Rampinini et al. (2007) observed that the work rate of professional soccer players was significantly influenced by the activity profile of their opponents. According
