    Tight Trip vs. Loose Grip on Russian Kettlebell Swing Work Capacity

    The purpose of this study was to examine the effects of a tight grip(TG) and a loose grip(LG) on work capacity while performing Russian kettlebell swings(KBS). It was hypothesized that LG would result in an ability to perform more work. Thirty fit adults (16 male; 14 female) were tested. Two (TG and LG) separate counterbalanced trials for each subject were collected, counting the number of repetitions completed until volitional exhaustion. RPE for forearms and overall exhaustion were collected post-trial. SPSS was used to run a paired samples t-test. There was a significant difference between the two grips (p = 0.013)(TG reps = 160.47±96.943; LG reps = 190.73±125.824). RPE forearms (p = 0.001)(TG = 7.10±1.698; LG = 5.79±2.177). RPE overall was not statistically significant (p = 0.475)(TG= 7.59±1.211; LG = 7.45±1.152). These results suggest grip firmness impacts performance, and using a LG while performing KBS increases work capacity. Strength coaches and athletes may use LG while performing KBS to increase work capacity

    Effects of Pre-Determined Barbell Hip Thrusting Surface Height on Motor Unit Recruitment and Activation Patterns

    Several variations of the barbell hip thrust that manipulate stance width and resistance type rather than surface height to better isolate muscle groups that act as prime movers for the exercise have been previously researched. The purpose of this study was to identify the effects of hip thrusting surface heights on neuromuscular activity in the gluteus maximus (GM), vastus lateralis (VL), and biceps femoris (BF). Twelve averagely fit, resistance trained individuals were recruited for this study. Participants completed a dynamic warm-up followed by 10 repetition max (RM) testing of the barbell hip thrust. Prior to trials, root mean square (RMS) values collected by surface electromyography(sEMG) during maximal voluntary isometric contractions of the (GM), (VL), and (BF) to enable data normalization. Three 10RM sets of the barbell hip thrust were performed on surface heights of 16.00 inches, 17.25 inches, and 18.50 inches. RMS values from each set were averaged across all 10 repetitions and statistical analysis was performed using a Friedman test with Wilcoxon post-hoc for significant differences. Kendall’s W was used to determine effect size. Results demonstrated no significant change in GM activity among all surface heights (x2(2)=1.167, W=0.049, p=0.558). A significant increase in activity of the VL was found with the Friedman test (x2(2)=8.000,W=0.333, p=0.018). With post-hoc analysis, the significant change only occurred from 16 inches to 18 inches (Z= -2.040, p=0.041). A significant decrease activity in the BF was also found with the Friedman test (x2(2)=10.5000, W=0.438; p=0.005), but the significant decrease was only found from 16 inches to 17 inches (Z= -2.353, p=0.019). Overall, no significant differences were found among bench heights for GM activation. However, as VL activation was found to increase as surface height increased, a higher bench height may be used to more efficiently recruit the VL during hip thrust. Conversely, as surface height decreased, the involvement of the BF increased. Study outcomes suggest that lower bench heights may be more efficient at recruiting the BF during the barbell hip thrust

    HIV clinic-based extended-release naltrexone versus treatment as usual for people with HIV and opioid use disorder: a non-blinded, randomized non-inferiority trial.

    BACKGROUND AND AIM: Opioid agonist medications for treatment of opioid use disorder (OUD) can improve human immunodeficiency virus (HIV) outcomes and reduce opioid use. We tested whether outpatient antagonist treatment with naltrexone could achieve similar results. DESIGN: Open-label, non-inferiority randomized trial. Setting was six US HIV primary care clinics. A total of 114 participants with untreated HIV and OUD (62% male; 56% black, 12% Hispanic; positive for fentanyl (62%), other opioids (47%) and cocaine (60%) at baseline). Enrollment halted early due to slow recruitment. INTERVENTION: HIV clinic-based extended-release naltrexone (XR-NTX; n = 55) versus treatment as usual (TAU) with buprenorphine or methadone (TAU; n = 59). MEASUREMENTS: Treatment group differences were compared for the primary outcome of viral suppression (HIV RNA ≤ 200 copies/ml) at 24 weeks and secondary outcomes included past 30-day use of opioids at 24 weeks. FINDINGS: Fewer XR-NTX participants initiated medication compared with TAU participants (47 versus 73%). The primary outcome of viral suppression was comparable for XR-NTX (52.7%) and TAU (49.2%) at 24 weeks. Non-inferiority could not be demonstrated, as the lower confidence limit of the RR did not exceed the pre-specified margin of 0.75 in intention-to-treat (ITT) analysis. The main secondary outcome of past 30-day opioid use was comparable for XR-NTX versus TAU in ITT analysis. Among those initiating medication, XR-NTX resulted in fewer days of opioid use compared with TAU in the past 30 days. CONCLUSIONS: A randomized controlled trial found supportive, but not conclusive, evidence that human immunodeficiency virus clinic-based extended-release naltrexone is not inferior to treatment as usual for facilitating human immunodeficiency virus viral suppression. Participants who initiated extended-release naltrexone used fewer opioids than those who received treatment as usual

    Inspired by Mitchell Roses\u27s Exquisite Corps, the Modern Dance III class came together virtually with a creative response to COVID-19, and turned disruption into an opportunity to connect our Ohio Northern University Theatre Arts students and faculty from a distance. The project’s intent was to keep us connected as a campus community
