The use of technology in sport and fitness training has rapidly become a tool for both athletes and coaches in monitoring performance variables for optimizing training stimulus and recovery (Duking, Hotho, Holmberg, Fuss, & Sperlich, 2016; Peake, Kerr & Sullivan, 2018). Wireless fitness trackers, GPS and accelerometry devices are growing in popularity with the athletic population outside of the clinical setting due to their lower cost and ease of use compared to traditional clinical measurement tools (Dellaserra, Gao & Ransdell, 2014). With the increased popularity of these devices comes the necessity to understand and validate the information collected from them …

The current investigation was an examination of the repetition-to-repetition magnitudes and changes in kinetic and kinematic characteristics of the back squat using accentuated eccentric loading (AEL) and cluster sets. Trained male subjects (age = 26.1 ± 4.1 years, height = 183.5 ± 4.3 cm, body mass = 92.5 ± 10.5 kg, back squat to body mass ratio = 1.8 ± 0.3) completed four load condition sessions, each consisting of three sets of five repetitions of either traditionally loaded straight sets (TL), traditionally loaded cluster sets (TLC), AEL cluster sets (AEC), and AEL straight sets where only the initial repetition had …

The purpose of this study was to examine the effects of a recovery supplement compared with a placebo on muscle morphology in trained weightlifters. Vastus lateralis and muscle fiber cross sectional area of type I and type II fibers were compared between groups using a series of 2 × 2 (group × time) repeated measure ANOVAs. Both groups on average improved cross-sectional area of the vastus lateralis, type I and type II muscle fibers from pre-to-post but individual response varied within both groups. Greater magnitude of changes in type I and type II muscle fibers were observed for the placebo …

Background: Gaining a better understanding of head impact exposures may lead to better comprehension of the possible effects of repeated impact exposures not associated with clinical concussion. Purpose: To assess the correlation between head impacts and any differences associated with cognitive testing measurements pre- and postseason. Study Design: Case-control study; Level of evidence, 3. Method: A total of 34 National Collegiate Athletic Association Division I men’s lacrosse players wore lacrosse helmets instrumented with an accelerometer during the 2014 competitive season and were tested pre- and postseason with the Sport Concussion Assessment Tool (SCAT 3) and Concussion Vital Signs (CVS) computer-based …

It is suggested that exercisers engage in a process of teleoanticipation and create an exercise template based upon previous experience with the exercise task which guides their perceptions of the amount of effort required for task completion. The present study examined how altering workload intensity during a positive-pressure treadmill task may impact ratings of perceived exertion (RPE). In a counter-balanced design, 15 collegiate cross country runners (7 males, 8 females) performed two 25-min runs at a constant velocity while bodyweight (BW) was either increased from 60% to 100% (INC) or decreased from 100% to 60% (DEC) in 5 min increments. …
