RETURN-TO-PLAY CRITERIA FOLLOWING ACL RECONSTRUCTION SURGERY: A CASE STUDY OVER NINE-MONTHS

This case study investigated changes in an injured athlete’s function, gait kinematics and parameters, and strength over nine months of ACL rehabilitation. The participant completed laboratory assessments at 6, 12, 24, and 36 weeks post-op, which included a functional outcome questionnaire, a gait evaluation with an electromagnetic tracking system and force plates, and a strength test with an isokinetic dynamometer. Left to right side differences in function, gait kinematics and parameters, and strength were assessed non-parametrically. Results indicated persistent strength disparities and dysfunction at terminal knee extension, even when return-to-play was approved clinically. Kinematics may be useful to guide a continuing rehabilitation program. Strength measures appear to be the most useful for describing rehabilitation progress and effectiveness

The Allometry of the Palate of Archaic \u3cem\u3eHomo sapiens\u3c/em\u3e and Modern \u3cem\u3eHomo sapiens\u3c/em\u3e

This research examines several aspects of allometry in the palate of archaic Homo sapiens and modern Homo sapiens. The allometry of the modern human palate is described. Comparisons between quantitative methods and comparisons between different types of samples are undertaken. Additionally, the allometry of the archaic Homo sapiens palate is described and analyzed. Finally, allometric comparisons between these groups are made. The samples employed in this study consist of 132 Amerindian (Arikara) crania and 21 archaic Homo sapiens (primarily Neandertal) crania. Quantitative methods used for analyzing these groups include least-squares regression, reduced major axis regression, and principal components analysis. Analysis of covariance and principal components analysis are used to compare allometric relationships between the groups. The results of this research indicate that least-squares regression techniques supply information which is generally substantiated by principal components analysis. Comparisons between samples indicate that static samples (samples derived from a single age group) do not provide the same information as ontogenetic samples (derived from several different age classes. These results are similar in both groups. The most important aspect of this study concerns the allometric relationships between modern and archaic Homo sapiens. Comparisons suggest that archaic Homo sapiens begin growth at larger sizes than modern Homo sapiens, and that this difference holds throughout the growth period. Complementary multivariate analyses indicate that the pattern or general size increase between these two groups is very similar

Discrimination, Coping, and Depression among Black Men Who Have Sex with Men

Black men who have sex with men (BMSM) have elevated risk for depression compared to the general population. BMSM’s capacity to cope with these experiences is not well understood. Increased understanding of how multiple forms of discrimination contribute to depression and how BMSM cope with discrimination can better inform interventions. Data come from 3,510 BMSM who attended Black Pride events in six U.S. cities from 2015-2017. Participants completed a health survey that ascertained their psychosocial health and resiliency profiles. Using multivariable logistic regression models, we tested the associations between type-specific discrimination (race, sexuality, HIV status) and depression. We then conducted sub-analyses to determine if coping attenuated the association between type-specific discrimination and depression. Our findings indicated that increased odds of depression among BMSM were associated with discrimination based on race (aOR=1.38, 95% CI = 1.08-1.76), sexual orientation (aOR=1.32, 95% CI = 1.01-1.72), and HIV status (aOR=1.53, 95% CI = 1.08-2.17). Sub-analyses indicated coping had inconsistent moderation effects between type-specific discrimination and depression. Our findings demonstrate that impact of various forms of discrimination on BMSM’s mental health and the mitigating role of coping. Interventions should seek to address depression by reducing experiences of discrimination and building coping resiliency

A CORRELATION BETWEEN VERTICAL JUMP AND ISOKINETIC MEASUREMENTS IN FEMALE BASKETBALL ATHLETES

The purpose of this study is to determine the relationship between isokinetic measurements and the vertical jump performance in female basketball athletes. The medical records and strength and conditioning measurements of 11 female NCAA-I basketball athletes were examined for vertical jump measurements and isokinetic measurements of the knee. This study found moderate to high correlation of the isokinetic measurements at 60o/sec (r2=0.9806)and 180o/sec (r2=0.9952)and vertical jump performance. The average power in the quadriceps at 60o/sec (p2= 0.8334)was the only variable that was significantly correlated with vertical jump height. The results demonstrate the possible influence of isokinetic variables such as power and peak torque on vertical jump performance

COMPARATIVE BIOMECHANICAL ANALYSIS OF A FEMALE HAMMER THROW ATHLETE FOR BACK-TO-BACK AMERICAN RECORD YEARS

Hammer athletes must optimize performance variables to maximize their official distance. Analysis of key performance variables might explain how the subject improved an American record year in 2018 to another record in 2019. A 3-D analysis was performed on trial videos from 2018 and 2019. Release height, release velocity, release angle, and hip-shoulder separation were compared among years and throws, and their relationship with official distance was assessed. Release height (p \u3c 0.01) and release angle (p \u3c 0.01) were more consistent in 2019 than 2018. The relationships among official distance, release height (p = 0.06), and hip-shoulder separation (p = 0.04) were different between years. The efficient use of hip-shoulder separation could be responsible for the increase in official distance between years

INFLUENCE OF LANDING QUADRANT ON ELLIPTICAL ORBIT AND ITS REALTION TO RELEASE PARAMETERS OF THE HAMMER THROW

Hammer throw official distance is determined by the velocity, angle, and height of the hammer at release, which is regulated by the acceleration arc of the hammer during the turns. This study aimed to examine the influence of position variables describing the elliptical orbit during each turn on the official distance and the release parameters. Competitive hammer throws from 35 athletes (17 men and 18 women) were digitized to obtain 3-D coordinates of the thrower and the hammer throughout the throw. Multiple regression models indicate that hammer positioning during turns 1 and 2 accounts for the greatest variance in the official distance. Male throwers use the acceleration arc to regulate the release angle throughout the throw, whereas female throwers use the acceleration arc to regulate both release velocity and release angle throughout the throw

PRINCIPLE COMPONENTS ANALYSIS TO CHARACTERIZE STRESS, PERFORMANCE, AND INJURY IN FEMALE COLLEGIATE SOCCER PLAYERS

Stress created by training is needed to elicit physiological adaptations to increase performance, however, a stress threshold exists. We assessed 19 female collegiate soccer players during an eleven week preparatory phase and measured stress, performance, and injury variables. We used a principal component analysis to determine relationships among stress, performance, and injury. We found a weak, negative relationship between practice stress and anaerobic stress (r = -0.107, p = 0.05), a positive relationship between anaerobic stress and movement risk of injury (r = 0.459,
