The purpose of this analysis was to investigate the association of injury risk and gender performance on health- and skill-related fitness assessments. A survey was used to collect personal characteristics and Army Physical Fitness Test scores (2-mile run, push-ups, and sit-ups). Within the same day, 9 physical fitness assessments were performed. Percent body fat was estimated using height, weight, age, and sex. All fitness assessment data were categorized into tertiles of high, moderate and low performance. To investigate potential injury risk predicted by fitness assessment performance, injury risk ratios, odds ratios (ORs), and 95% confidence intervals (CIs) were calculated using medical record data. A total of 3,264 soldiers completed surveys and physical fitness assessments. Tertiles of fitness performance with men and women combined showed that on an average, 14% of women and 70% of men were in the moderate- and high-performance groups. Among men, higher injury risk was independently associated with low performance on a 2-mile run (ORslow/fast - 1.51, 95% Cl 1.18-1.94) and low performance on a weighted 300-yard shuttle run (ORslow/fast - 1.36, 95% Cl 1.06-1.74). For women, a higher risk of injury was associated with low performance on the 2-mile run (ORslow/fast - 2.38, 95% Cl 1. 04-5.74). Therefore, out of the 13 fitness assessments, the 2-mile run and weighted 300-yard shuttle run can also (in addition to measuring performance) be utilized to identify soldiers or athletes who are at a higher risk of experiencing an injury.

The aim of this article was to determine the validity and reliability of a submaximal intermittent running (SIR) test in elite Australian rules football (ARF) players. Heart rate (HR) responses of 38 elite ARF players to both the SIR and the yo-yo intermittent recovery 2 (YYIR2) tests were compared over 2 trials. Linear regression analysis was used to examine the relationship between SIR test HR responses and YYIR2 test performance. Heart rate responses of 25 elite ARF players to the SIR test were monitored over 3 trials. Day-to-day reliability was determined using intraclass correlation coefficient (ICC), typical error of measurement, coefficient of variation (CV), and smallest worthwhile change. Large inverse correlations were reported between 2-, 3-, and 4-minute HR during the SIR test and YYIR2 test distance (r = 20.58 to 20.61, p < 0.01). Heart rate recovery after 2 and 3 minutes of the SIR test was moderately correlated to YYIR2 distance (r = 0.32-0.35, p ≤ 0.05). Strong correlations for ICC (r = 0.90-0.97) and low CV (1.3-9.2%) were reported for all HR variables. Monitoring HR during the SIR test is a valid and reliable indicator of YYIR2 test performance in elite ARF players. These findings support the use of the SIR test as a regular and non-fatiguing indicator of intermittent running capacity. [ABSTRACT FROM AUTHOR]

The article discusses a study which was aimed to examine physiologic performance test differences by competition level and player position in 4 volleyball-related tests. The study also aimed to establish whether a 1 50-yd shuttle could be used as a field test to assess anaerobic capacity. The study suggested that female high school volleyball players may enhance their ability to play collegiate volleyball by improving their vertical jump, lower-body power, and agility.

The article presents the results of a study which investigated the usefulness of a field test for assistant soccer referees, designed to assess their ability to change direction. An overview of related previous research is provided, along with details of the experimental protocol. The field test was found to possess statistical significance and reliability.

The article presents information on a test of agility and fitness developed for rugby league football players. An overview of related previous research and tests is provided, along with details of the protocol. The test involves measuring players' speed when changing direction, and their perception and reaction times.
