New Criteria

This paper investigates the impact of changes in judging criteria on 10-8 scores in Zuffa-owned mixed martial arts (MMA) promotions. Utilizing a differences-in-differences framework, the 2017 liberalization of 10-8 scoring criteria in the Unified Rules of MMA is examined across various judge groups. Findings suggest that traveling judges and Nevada judges – those most likely to be at the forefront of the regulatory evolution of the sport – had already liberalized their 10-8 scoring one year prior to the effective date of the new criteria. Other judges appear to have effectively implemented the new criteria since January 2017 with 10-8 probabilities on par with traveling and Nevada judges. The effect of an earlier change in judging criteria is also examined in Nevada. Results suggest the numerous and distributed regulatory agencies involved in the sport of MMA were effective in the implementation of new policies for scoring rounds.

The Impact

This research sought to establish the impact of a 10-week program combining mixed martial arts (MMA) and one-to-one psychotherapy on young males’ mental health and determine factors that predict help-seeking behavior in at-risk males. Preparticipation and post-participation interviews were employed as the method of data collection. Seven males (20–35 years; M = 24.57) completed preparticipation interviews and five completed follow-up interviews. Thematic analysis of preparticipation revealed that help-seeking behavior in at-risk males is impeded by the presence of male gender stereotypes, the absence of positive role models, as well as difficulty navigating challenging social landscapes. Post-participation interviews revealed that the sport provided structure and fitness for at-risk males, while the counseling was pivotal for personal growth. Improved relationships, work life, and self-esteem were also observed. The sporting element of the program helped to reduce stigma associated with engaging in psychotherapy, and positive male relationships were noted as particularly impactful. Findings support previous research indicating that combining sports and psychotherapy positively impacts young males’ mental health. Sport provides an acceptable doorway to psychotherapy, providing space to explore personal issues.

The Impact

Concern about the consequences of head impacts in US football has motivated researchers to investigate and develop instrumentation to measure the severity of these impacts. However, the severity of head impacts in unhelmeted sports is largely unknown as miniaturised sensor technology has only recently made it possible to measure these impacts in vivo. The objective of this study was to measure the linear and angular head accelerations in impacts in mixed martial arts, and correlate these with concussive injuries. Thirteen mixed martial arts fighters were fitted with the Stanford instrumented mouthguard (MiG2.0) participated in this study. The mouthguard recorded linear acceleration and angular velocity in 6 degrees of freedom. Angular acceleration was calculated by differentiation. All events were video recorded, time stamped and reported impacts confirmed. A total of 451 verified head impacts above 10g were recorded during 19 sparring events (n = 298) and 11 competitive events (n = 153). The average resultant linear acceleration was 38.0624.3g while the average resultant angular acceleration was 256761739 rad/s2. The competitive bouts resulted in five concussions being diagnosed by a medical doctor. The average resultant acceleration (of the impact with the highest angular acceleration) in these bouts was 86.7618.7g and 756163438 rad/s2. The average maximum Head Impact Power was 20.6kW in the case of concussion and 7.15kW for the uninjured athletes. In conclusion, the study recorded novel data for sub-concussive and concussive impacts. Events that resulted in a concussion had an average maximum angular acceleration that was 24.7% higher and an average maximum Head Impact Power that was 189% higher than events where there was no injury. The findings are significant in understanding the human tolerance to short-duration, high linear and angular accelerations.

Abstract The STEADI Options trial uses a randomized, controlled-trial design to assess the effectiveness and cost-effectiveness of the STEADI Initiative . Beginning March, 2020, we will randomize 3,000 adults ≥ 65 years of age at risk for falls seen in an Emory Clinic primary care practice to: (1) full STEADI; (2) a STEADI-derived gait, balance, and strength assessment with physical therapy referrals; (3) a STEADI-derived medication review and management; or (4) usual care. This presentation will discuss decisions made by the study team to facilitate implementation of STEADI including electronically conducting screening prior to the date of encounter, the use of dedicated nursing staff to conduct assessments, implementation of strength, balance, orthostatic hypotension, and vision testing, methods to facilitate medication review, and communication of assessment information to providers. The results from this study will be used to estimate the impact of STEADI on falls, service utilization, and costs over one year.

Abstract Background Limited information has been reported regarding the impact of percutaneous mitral valve repair (PMVR) on ventricular arrhythmic (VA) burden. The aim of this study was to address the incidence of VA and appropriate antitachycardia implantable cardiac defibrillator (ICD) therapies before and after PMVR. Methods We retrospectively analyzed all consecutive patients with heart failure with reduce left ventricular ejection fraction, functional mitral regurgitation grade 3+ or 4+ and an active ICD or cardiac resynchronizer who underwent PMVR in any of the eleven recruiting centers. Only patients with complete available device VA monitoring from one-year before to one year after PMVR were included. Baseline clinical and echocardiographic characteristics were collected before PMVR and at 12-months follow-up. Results 93 patients (68.2±10.9 years old, male 88.2%) were enrolled. PMVR was successfully performed in all patients and device success at discharge was 91.4%. At 12-months follow-up, we observed a significant reduction in mitral regurgitation severity, NT-proBNP and prevalence of severe pulmonary hypertension and severe kidney disease. Patients also referred a significant improvement in NYHA functional class and showed a non-significant trend to reserve left ventricular remodeling. After PMVR a significant decrease in the incidence of non-sustained ventricular tachycardia (VT) (5.0–17.8 vs 2.7–13.5, p=0.002), sustained VT or ventricular fibrillation (0.9–2.5 vs 0.5–2.9, p=0.012) and ICD antitachycardia therapies (2.5–12.0 vs 0.9–5.0, p=0.033) were observed. Conclusion PMVR was related to a reduction in arrhythmic burden and ICD therapies in our cohort. Proportion of patients who presented ven Funding Acknowledgement Type of funding source: None

Zusammenfassung Mixed Martial Arts (MMA) hat sich global und auch in Deutschland sukzessive zu einem sportkulturellen Mainstream-Phänomen entwickelt. Vorliegender Artikel untersucht die diskursiven und praktischen Logiken, nach denen sich das Feld des MMA organisiert. Der soziologische Blick auf MMA-Wettkämpfe zeigt, dass diese über körperlich relativ ungefährliche Performanzen eine Ästhetik körperlicher Gefährdung und darüber Vorstellungen von kämpferischer Authentizität herstellen. Basierend auf empirischem Material erweitert der Artikel den soziologischen Blick, indem er das MMA-Training untersucht. Auch hier finden, insbesondere in der Trainingspraxis des Sparrings, praktische Konstruktionen von Vorstellungen kämpferischer Authentizität statt. Einerseits erfolgt dies darüber, dass die Praxiskonfiguration des Sparrings die kontrollierte Herstellung eines Erlebnisses kämpferischer Unkontrolliertheit ermöglicht. Andererseits erfolgt es darüber, dass die Praxiskonfiguration die Trainierenden ihr Kampftraining in spezifischer Weise als kämpferisch besonders radikal und endgültig erleben lässt.
