Establishing Normative Reference Values for the Utah Seated Medicine Ball Throw Protocol in Adolescents

Abstract:

The seated medicine ball throw (SMBT) is a field test intended to assess upper-body muscular power by measuring the maximal distance an individual can throw a medicine ball from an isolated, seated position (25). The SMBT has been used to assess upper-body power in various populations and to establish concurrent validity for other measures of upper-body power such as the bench press power test and the plyometric push-up. The SMBT is less costly and simpler to incorporate into a field test battery than other upper body power assessments. While the SMBT is a valid, reliable field test for upper-body power, normative reference standards for most populations, including adolescent (12-15 years old) physical education students, do not exist. Purpose: This study reports distances thrown in the SMBT to establish normative reference values in male and female physical education students, ages 12-15 years old. Methods: One hundred thirteen untrained male and female physical education students aged 12-15 years performed the SMBT field test three times on a single testing day. Participants threw a 2 kg medicine ball with a 19.5 cm diameter while seated on the floor with the upper torso against the wall (legs extended, trunk angle 90°). Likewise, age, height, and body mass were assessed. Results: Participant data was separated by age gender for analysis. Mean and standard deviation for the SMBT for males was 4.3 ± 0.7 m and 5.2 ± 0.8 m for ages 12-13 and 14-15, respectively, and for females was 3.4 ± 0.5 m and 3.7 ± 0.5 m for ages 12-13 and 14-15, respectively. Pearson correlation coefficients (i.e. PCCS or r) were calculated for trial pairs (i.e. T1 vs T2, T2 vs T3, T3 vs T1) for both female and males at age groupings of 12-13 and 14-15. The aforementioned PCCs ranged from r = 0.85-0.97. Normative reference values as percentile ranks for the SMBT scores for age groups 12-13 and 14-15 among males and females, respectively, were also established. Conclusion: The data presented provides an initial set of normative reference standards for coaches and students to determine upper-body muscular power using the SMBT.

Movement Competency Screen Predicts Performance in Female Military Academy Recruits

ABSTRACT
Musculoskeletal injuries in military populations are a leading cause for reduced physical readiness (15). Utilizing a screening tool that predicts physical performance and injuries could help identify recruits who need remedial training or conditioning. The Movement Competency Screen (MCS) identifies poor movement patterns and suggests safe load levels for individuals (8). This study sought to establish the predictive ability of the MCS for injuries and performance in United States Naval Academy (USNA) recruits over four years. Fifteen female and 26 male recruits completed the MCS upon entry into the academy. The recruits’ Physical Readiness Test (PRT) scores and injury data were collected for eight semesters. Correlations between MCS scores and recruits’ number of injuries, missed “duty days”, and region of injury were identified using Pearson correlation coefficients. Additionally, correlations between MCS scores and recruits’ overall PRT score, number of push-ups, curl-ups, and their 1.5-mile run time were calculated. Within the first year at USNA recruits’ MCS scores correlated with the number of injuries and missed “duty days”; however, this correlation was not sustained. Recruits also experienced the most injuries in the first year. For female recruits, higher MCS scores correlated with better PRT scores, number of push-ups, and 1.5 mile run times. With its high inter- and intra-rater reliability (12), the MCS could be used to identify poor movement patterns and guide remedial training to help prevent future injury. Further research should focus on a larger military population to determine if the MCS’s predictive abilities go beyond a military academy population.

The Reliability and Predictive Ability of the Movement Competency Screen in a Military Population

ABSTRACT:
Purpose: Musculoskeletal injuries in the United States Armed Forces impacts operational readiness. Therefore, a reliable, valid screening tool that identifies injury risk and predicts performance is needed. The purpose of this study was to: (1) establish the intra- and inter-rater reliability of the Movement Competency Screen (MCS) using a cohort of United States Naval Academy fourth class Midshipmen, (2) identify if a correlation exists between average total MCS scores and injury rates during training, and (3) identify if a correlation exists between average total MCS score and performance on the Physical Readiness Test (PRT).
