Journal: Differences in head impact biomechanics between playing positions in Canadian high school football players. (Pubmed Central) - Mar 3, 2023
Thirty nine players from two high-school football teams were recruited and assigned a position profile: Profile 1 (quarterback, receiver, defensive back, kicker), Profile 2 (linebacker, running back), and Profile 3 (linemen)...Time between impacts was lowest in Profile 3, followed by Profiles 2 and 1. This study delivers a new method of reducing the multidimensionality of head impact magnitudes and suggests different Canadian high-school football playing positions experience different head impact magnitudes and frequencies, which is important for monitoring concussion and repetitive head impact exposure.

Journal: Player Position and Labral Tear Location and Size in NCAA Division I Football Players Undergoing Arthroscopic Surgery. (Pubmed Central) - Nov 16, 2022
Players were divided into 3 groups: line players (offensive and defensive linemen, defensive end), skill players (defensive back, wide receiver, running back, and quarterback), and hybrid players (linebacker and tight end)...There was a positive correlation between labral tear size and number of suture anchors (0; P = .010). In this study of NCAA Division I football players, skill players had a higher proportion of anteroinferior labral tears, and hybrid players had a higher proportion of posterosuperior labral tears.

Journal: Shoulder, upper arm and elbow injuries in high school men's American football. (Pubmed Central) - Sep 20, 2022
Most injuries occurred in older athletes (juniors and seniors, 30% and 32%, respectively), were related to tackling (31%), and in running back and linebacker positions (15% each). Orthopaedic surgeons and other sports medicine specialists can use these findings to educate players, coaches and families about injury risks and for improving injury prevention guidelines.

Journal: The Applicability of the Risk Score Approach to Competitive Sport: Development of a Physical Success Score for the Canadian Football League Combine. (Pubmed Central) - Feb 23, 2022
To do so, a repeated grid-search cross-validation for variable selection algorithm was performed on the players (line: n = 211, big skill linebacker, running back and tight end: n = 177, skill [defensive back and wide receiver]: n = 231) who participated in the CFL Combines between 2011 and 2019...In each group, all possible total scores and the estimated draft success probability were shown. From the results of this study, it was concluded that the PSS approach can provide useful information for coaches in setting training goals.

Journal: Position-Specific Physical Workload Intensities in American Collegiate Football Training. (Pubmed Central) - Feb 2, 2022
Players were involved in individualized skill (indy), team playbook (team), and special team (ST) drills during practice and analyzed for their specialist offensive or defensive role (e.g., linebacker or wide receiver)...The findings may be informative for coaches to tailor physical workloads of practice drills for positional roles in preparation for games and practices. Player tracking technology can add value for strength and conditioning coaches to adjust training programs based on position-specific on-field demands of players.

Journal: Normative reference values for high school-aged American football players. (Pubmed Central) - Feb 3, 2021
Each player self-classified their American football positions as defensive back, defensive end, defensive linemen, linebacker, offensive linemen, quarterback, running back, tight end (TE), or wide receiver...These normative reference values may provide realistic comparisons and evaluations in performance for young American football players, parents, and coaches with collegiate football aspirations. High school strength and conditioning professionals should use these norms to set attainable goals and reward accomplishments for young football players.

Journal: The Effect of Thursday Night Games on In-Game Injury Rates in the National Football League. (Pubmed Central) - Nov 12, 2020
For player position, only the tight end, linebacker, and fullback group demonstrated significant differences between the injury rates for different rest categories...A short rest period between games is not associated with increased rates of observed injuries reported in NFL game books; rather, our data suggest there are significantly fewer injuries for Thursday night games compared with games played on regular rest. Future research correlating rest and quarterback injury rates is warranted.

Each player self-classified their American football positions as defensive back, defensive end, defensive linemen, linebacker, offensive linemen (OL), quarterback (QB), running back, tight end, or wide receiver...Greater percent differences for all 3 variables were observed between freshman and sophomore years than between sophomore and junior years. These normative reference values will be useful for athletes, parents, coaches, and high school strength and conditioning professionals to set realistic goals for young American football athletes.

Journal: National Football League Scouting Combine Tests Correlated to National Football League Player Performance. (Pubmed Central) - Sep 21, 2020
The correlation between NFL Scouting Combine test results and NFL player performance is frequently questioned, and thus this study endeavored to identify significant relationships between NFL Scouting Combine test results and NFL player performance indicators for all offensive and defensive positions, including quarterback (n = 107), fullback (n = 31), running back (n = 228), wide receiver (n = 336), tight end (n = 137), offensive tackle (n = 204), guard (n = 128), center (n = 66), cornerback (n = 276), free safety (n = 92), strong safety (n = 96), outside linebacker (n = 215), inside linebacker (n = 116), defensive end (n = 212), and defensive tackle (n = 223)...These results can be useful for those in charge of making player personnel decisions in the NFL, such as general managers, draft analysts, and scouts by helping them select NFL prospects. Furthermore, these results could inform strength and conditioning coaches in preparing athletes to excel in the NFL.

Journal: Potential of Flavonoid-Inspired Phytomedicines against COVID-19. (Pubmed Central) - Jun 28, 2020
Meanwhile, in vitro studies show potential of caflanone to inhibit virus entry factors including, ABL-2, cathepsin L, cytokines (IL-1β, IL-6, IL-8, Mip-1α, TNF-α), and PI4Kiiiβ as well as AXL-2, which facilitates mother-to-fetus transmission of coronavirus. The potential for the use of smart drug delivery technologies like nanoparticle drones loaded with these phytomedicines to overcome bioavailability limitations and improve therapeutic efficacy are discussed.
