Influence of training years on upper-body strength and power changes during the competitive season for professional Australian rules football players

Background: Physical performance demands of the rugby union (RU) game have increased over the past two decades. However, there are little data on these variables concentrating on developing RU players (student-athletes) over a competitive season. Objectives: To investigate the potential enhancement of two physical anthropometrical and nine physical performance variables of male New Zealand RU Academy student-athletes over a competitive season and compare with similar published data. Methods: Twenty student-athletes were recruited to the Otago Rugby Football Union (ORFU) two-year Academy Programme. Each week the student-athletes engaged in 25 hours of strength and conditioning training and participated in 15 hours of on-field rugby training with their respective ORFU Premier League team. Assessments sessions were scheduled for the start of the season, in-season, and pre-play-offs (week 31). Results: Mean data from 20 student-athletes demonstrated a trivial effect size (ES) increase in body weight and skinfold measurements, while a paired t-test (p<0.05) resulted in concurrent significant improvements in lower-body power (ES = large), acceleration (ES = large), speed (10 m sprint, ES = small, 40 m sprint, ES = small), and upper body strength (bench press, ES = large and bench pull, ES = small). A non-significant physical performance improvement, with trivial ES difference, was also noted in anaerobic endurance performance. Conclusion: Based on these data significant physical performance enhancements were observed during in-season Premier League competition while limiting fatigue and overtraining.

Comparison of Division II College Offensive and Defensive Football Players' Upper Body Strength Across One Repetition Maximum Test and The NFL-225 TestThe purpose of this study was to evaluate the effectiveness of predicting actual one repetition maximum (1RM) bench press strength from the National Football League (NFL) 225-test in college football players. Forty-one Division II college football players participated in this study. Participants' upper body strength scores were expressed relative to body weight and results were compared across both tests. Mayhew et al. equation was used to predict 1RM. A repeated measures ANOVA and one-way ANOVA was used to compare the groups. The present study found that the Mayhew equation overestimated relative upper body strength of college football players, while high degree of reliability was found between the actual 1RM and the NFL-225 tests [Wilks λ = 0.43, F (1,40) = 53.07, p = 0.000, Eta-squared = 0.57] and the correlation between these two tests was very high (r = 0.94, p<0.001). The present study also found that defensive players were stronger than offensive players when scores were expressed relative to body weight. The finding of this study indicates that the NFL-225 test's applicability may not be identical for all college players. This study elucidates some of the difficulties associated with predicting 1RM. However, while it is difficult to predict 1RM, testing using sub-maximal loads are far less time consuming especially when they involve a large number of athletes. The results of this study should facilitate coaches in choosing the most appropriate strength testing procedure for their programs.

Puberty and the onset of menarche influences the motor performance of girls. However, the magnitude of these influences during varying maturity status, is not clear. This longitudinal study over two years aimed to investigate differences in motor fitness between early and late developing girls based on pre- and post-menarche status. A convenience sample (n = 58) of girls aged 13.51 ± 3.51, divided by means of the Status Quo method into pre (n = 13) and post-menarche (n = 45) groups, was used. Motor fitness was tested once annually by standardized protocols. Basic statistics, independent t-testing and a repeated measures ANOVA with a post hoc Bonferonni correction were used (p < 0.05 = statistical significance). Effect sizes were determined by Cohen’s d-values. Only explosive upper body strength differed significantly between groups during baseline, favoring post-menarche girls. Initially, post-menarche girls showed advantages in hand-eye coordination and speed (p > 0.05) with pre-menarche girls performing better in agility and explosive leg strength (p > 0.05). At 15.51 years, no significant, between-group differences were found. Pre-menarche girls surpassed post-menarche girls in hand-eye coordination and 0–40 m speed and post-menarche girls displayed higher explosive leg and upper body strength scores (p > 0.05). Our data show that the potential to excel in sport based on motor capabilities can only be accurately estimated 1–2 years after reaching menarche.
