; Lim, Huang, Wu, Girardi, & Cammisa, 2007 ). PD also leads to changes in gait power profiles at the ankle, knee, and hip, which account for reduction in stride length and gait speed ( Lim et al., 2007 ; Morris, Huxham, McGinley, Dodd, & Iansek, 2001 ; Sofuwa et al., 2005 ; Winter, 1987 ). Growing

Metabolic power ( P met ) has been proposed as a tool to estimate the energetic demands of variable-speed locomotion typically seen in team sports. 1 From the outset, it should be stated that this model is not able to fully account for the physical demands of team-sport activity, 2 , 3 but nor

based on several (2–5) 30-minute tests performed on different days, 2 thus requiring several visits to the laboratory, which is not practical and accessible for many athletes. In cycling, one of the most well-known and controversial concepts is the functional threshold power (FTP), which is defined as

affordability of power meters, more practical field test-based markers that can be conducted regularly have been proposed as surrogates of the LT. 2 One of the most commonly used field-test methods for the estimation of the LT is the functional threshold power (FTP), which has been defined as the highest power

usefulness as a vertical-jump performance metric. Although RSImod was shown to be related to force and power characteristics of the unloaded CMJ, such as rate of force development ( r  = .56–.66), peak force ( r  = .37–.50), and peak power ( r  = .47–.69), 4 that study only included “gross” measures of CMJ

these competitions, HR was 177 (6) beats·min −1 and power output (PO) averaged 246 (12) W (3.6 [0.2] W·kg −1 ), but was highly variable (coefficient of variation of 69%) and characterized by regular repeated high-intensity bursts. Although these HR and PO data provide a general understanding of

positively associated with skeletal health ( 23 ). MF can be defined by measurements of muscular strength, muscular power, and muscular endurance ( 11 , 17 ). As children are more inclined to engage in short bursts of movement throughout the day rather than long-term activities, short-term muscular power is

The decays of maximal aerobic power (MAP) and of anaerobic capacity were recently estimated in cycling master athletes from 35 to 80 years of age by analyzing their absolute best performances in track competitions. 1 It was suggested that MAP would start declining after 45 years of age, with an

flexion strength and power, (3) barbell velocity in resistance exercise, and (4) whole-body power output. We hypothesized that caffeine in this form would elicit an ergogenic effect in all explored aspects of exercise performance. Methods Experimental Design This study employed a randomized, cross
