Position-Specific Physical Workload Intensities in American Collegiate Football Training

The risk of a needle stick or sharps injury in the operating room (OR) is high due to conditions such as minimal physical protective measures, frequent transfer of sharps, and reliance on human attention and skill for injury avoidance. An ergonomic process improvement project was initiated at a large metro teaching hospital to identify ergonomic risk factors for these OR injuries. To maximize the engagement of the front- end users, an ergonomic process improvement (EPI) team was developed, consisting of representatives from participating OR teams, an employee health nurse and two ergonomists. Surveys, observations, and interviews were conducted to quantify injury risk for the OR teams, evaluate barriers to best practice adherence, and identify opportunities for targeted interventions. Risk mapping was completed for the surgeons, surgical techs and OR nurses identifying double gloving and safe passing zone as areas in need of improvement. Through observation and interviews, researchers identified physical factors relating to musculoskeletal pain and cognitive factors leading to distractions as safety risk concerns. The overall success of the EPI was the engagement of the OR teams and surgeons in the process of identifying risk factors and potential opportunities for ergonomic solutions related to cognitive workload, physical workload, teamwork, and work design for injury prevention. The risk factors identified will provide the basis for developing targeted, effective interventions for eliminating injuries from needles and sharps within the OR.

The main objectives of this study were to evaluate the short-term effects of resisted sprint and plyometric training on sprint performance together with lower limb physiological and functional performance in collegiate football players. Ninety collegiate football players participated in this three-arm, parallel group randomized controlled trial study. Participants were randomly divided into a control group and two experimental groups: resisted sprint training (RST) (n = 30), plyometric training (PT) (n = 30), and a control group (n = 30). Participants received their respective training program for six weeks on alternate days. The primary outcome measures were a knee extensor strength test (measured by an ISOMOVE dynamometer), a sprint test and a single leg triple hop test. Measurements were taken at baseline and after 6 weeks post-training. Participants, caregivers, and those assigning the outcomes were blinded to the group assignment. A mixed design analysis of variance was used to compare between groups, within-group and the interaction between time and group. A within-group analysis revealed a significant difference (p < 0.05) when compared to the baseline with the 6 weeks post-intervention scores for all the outcomes including STN (RST: d = 1.63; PT: d = 2.38; Control: d = 2.26), ST (RST: d = 1.21; PT: d = 1.36; Control: d = 0.38), and SLTHT (RST: d = 0.76; PT: d = 0.61; Control: d = 0.18). A sub-group analysis demonstrated an increase in strength in the plyometric training group (95% CI 14.73 to 15.09, p = 0.00), an increase in the single leg triple hop test in the resisted sprint training group (95% CI 516.41 to 538.4, p = 0.05), and the sprint test was also improved in both experimental groups (95% CI 8.54 to 8.82, p = 0.00). Our findings suggest that, during a short-term training period, RST or PT training are equally capable of enhancing the neuromechanical capacities of collegiate football players. No adverse events were reported by the participants.

ObjectiveTo understand human factors (HF) contributing to disturbances during invasive cardiac procedures, including frequency and nature of distractions, and assessment of operator workload.MethodsSingle centre prospective observational evaluation of 194 cardiac procedures in three adult cardiac catheterisation laboratories over 6 weeks. A proforma including frequency, nature, magnitude and level of procedural risk at the time of each distraction/interruption was completed for each case. The primary operator completed a National Aeronautical and Space Administration (NASA) task load questionnaire rating mental/physical effort, level of frustration, time-urgency, and overall effort and performance.Results264 distractions occurred in 106 (55%) out of 194 procedures observed; 80% were not relevant to the case being undertaken; 14% were urgent including discussions of potential ST-elevation myocardial infarction requiring emergency angioplasty. In procedures where distractions were observed, frequency per case ranged from 1 to 16 (mean 2.5, SD ±2.2); 43 were documented during high-risk stages of the procedure. Operator rating of NASA task load parameters demonstrated higher levels of mental and physical workload and effort during cases in which distractions occurred.ConclusionsIn this first description of HF in adult cardiac catheter laboratories, we found that fewer than half of all procedures were completed without interruption/distraction. The majority were unnecessary and without relation to the case or list. We propose the introduction of a ‘sterile cockpit’ environment within catheter laboratories, as adapted from aviation and used in surgical operating theatres, to minimise non-emergent interruptions and disturbances, to improve operator conditions and overall patient safety.
