Physical Demands And Salivary Immunoglobulin A Responses Of Elite Australian Rules Football Athletes To Match Play, Sam Coad, Bon Gray, George Wehbe, Christopher Mclellan

Purpose: To examine the response or pre- and postmatch salivary immunoglobulin A concentration ([s-IgA]) to Australian Football League (AFL) match play and investigate the acute and cumulative influence of player workload and postmatch [s-IgA] after repeated participation in AFL match play. Methods: Eleven elite AFL athletes (21.8 ± 2.4 y, 186.9 ± 7.9 cm, 87.4 ± 7.5 kg) were monitored throughout 3 matches during the preseason that were separated by 7 d. Saliva samples were collected across each AFL match at 24 h and 1 h prematch and 1, 12, 36, and 60 h postmatch to determine [s-IgA]. Global positioning …

The aim of the present study was to examine the competitive physiological movement demands of National Collegiate Athletic Association (NCAA) Division I college football players using portable global positioning system (GPS) technology during games and to examine positional groups within offensive and defensive teams, to determine if a player's physiological requirements during games are influenced by playing position. Thirty-three NCAA Division I Football Bowl Subdivision football players were monitored using GPS receivers with integrated accelerometers (GPSports) during 12 regular season games throughout the 2014 season. Individual data sets (n 295) from players were divided into offensive and defensive teams and …

Validity And Reliability Of A Novel Salivary Immunoassay For Individual Profiling In Applied Sports Science, Sam Coad, Chris Mclellan, Tim Whitehouse, Bon Gray

The aim of this study was to examine the validity and reliability of a novel immunoassay, developed to assess salivary Immunoglobulin A (s-IgA). Validity and reliability of the Individual Profiling Lateral Flow Device (IPRO LFD) for s-IgA concentrations ([s-IgA]) was assessed in males (n = 12) and females (n =13) who were involved in recreational activities. Reliability of the IPRO LFD method was assessed by comparing [s-IgA] of two saliva samples collected concurrently, while validity was assessed by comparing with an enzyme-linked immunosorbent assay (ELISA) method. The IPRO LFD had a strong positive correlation (r = 0.93, p < 0.001), with no difference in [s-IgA] compared with the ELISA. The IPRO LFD was considered reliable (ICC r = 0.89, p < 0.001 and CV = 9.40 %) for measures of [s-IgA]. We concluded that the IPRO LFD method may be a substitute to the ELISA method for measurements of [s-IgA].

The aim of this study was (a) to examine the physiological demands of competitive Rugby League match play using portable Global Positioning Systems (GPSs) to monitor players' movement patterns and heart rate (HR) and (b) examine positional comparisons to determine if players' physiological requirements are influenced by their playing position during Rugby League match play. Twenty-two elite male Rugby League players were monitored during 5 regular season competition matches using portable GPS software. There was no difference in the total distance traveled between backs (5,573 ± 1,128 m) and forwards (4,982 ± 1,185 m) during match play. Backs and forwards …
