Item Implementation and evaluation of a simulation-based team training program within an unstable pediatrics course utilizing the TeamSTEPPS® 2.0 framework(Montana State University - Bozeman, College of Nursing, 2018) Butterly, Kathryn Margaret; Chairperson, Graduate Committee: Jennifer SofieAccording to the Agency for Healthcare Research and Quality (AHRQ), ineffective communication and teamwork are two leading causes of medical errors in the United States. The Institute of Medicine (IOM) recommended that healthcare facilities employ measures to improve patient care and safety including teamwork training. Poor communication and lack of teamwork have been found to be the common denominator in up to 70% of serious or fatal medical errors. The Joint Commission and the IOM recognized that successful teamwork is critical for positive patient outcomes. TeamSTEPPS® 2.0 is an evidenced-based approach to developing and supporting teamwork in the healthcare setting with a focus on communication, mutual support, situational monitoring, leadership, and team structure. A simulation-based team training event, guided by the TeamSTEPPS® 2.0 framework, was added to an unstable pediatrics course at a rural Montana community hospital. The purpose of this scholarly project was to implement a simulation-based team training (SBTT) component as part of a comprehensive interdisciplinary unstable pediatrics course. Evaluation of the team training included teamwork attitudes, teamwork perceptions, team performance, and participant satisfaction. Twenty employees of a community hospital participated in the unstable pediatrics course. Total teamwork attitudes in all five sub-constructs improved (p=0.0001). Teamwork perceptions improved in communication, leadership, mutual support, and situational monitoring after the training. Participants agreed or strongly agreed when rating satisfaction with the learning modality of SBTT. Observed team performance improved after the SBTT. The results indicate favorable outcomes for use of the TeamSTEPPS framework with SBTT.Item Olympic training center(Montana State University - Bozeman, 1985) MacDonald, Michael FranzelItem Progressive changes in the physical fitness of a female long-distance runner in training for the Western States 100(Montana State University - Bozeman, 1980) Dearborn, Donna WinnifredItem Dietary influences on selected physiological parameters in collegiate wrestlers during the pre-competitive training period(Montana State University - Bozeman, College of Education, Health & Human Development, 1984) Jensen, Don WayneItem Vertical jump training : the Kor trainer vs. conventional training(Montana State University - Bozeman, College of Education, Health & Human Development, 2003) Erickson, Minde RaeItem Distribution of seasonal training intensity in competitive masters-level cross country skiers(Montana State University - Bozeman, College of Education, Health & Human Development, 2014) Ranta, Emily Christian; Chairperson, Graduate Committee: Daniel P. Heil; Tara K. Vetrone, Daniel P. Heil, Mary P. Miles, and John G. Seifert were co-authors of the article, 'Distribution of seasonal training intensity in competitive masters-level cross country skiers' submitted to the journal 'European journal of applied physiology' which is contained within this thesis.Professionals have long debated the optimal distribution of training volume and intensity necessary for improved performance by endurance athletes. Although researchers have studied the training distributions of high-level cross country (XC) skiers, the unique population of Masters-level XC skiers has been largely overlooked. Therefore, the primary purpose of this study was to characterize the changes in Masterslevel skiers' training volume and intensity from the fall to mid-winter seasons using telemetry-based heart rate (HR) monitoring. The secondary purpose was to determine the relationship between winter training variables and race speed within the same population. Fifty-six Masters-level skiers volunteered to don a HR monitor and utilize a training log to record all bouts of physical activity over two 14+ day periods designed to correspond with the preparatory (fall) and pre-competition (mid-winter) seasons. After the midwinter collection period, the same subjects recorded HR data while competing in a 34.4 km ski race. All HR data were downloaded to a computer and summarized by absolute training time (T, min) and relative time (%T) spent within six HR zones (Z) which were calculated as percentages of age-predicted maximum HR (APMHR). Training variables were compared using two-factor and three-factor multivariate repeated measures ANOVAs, whereas winter training variables and race HR variables were correlated with race speed using the Pearson product-moment correlation. Only 13 men (Mean±SD: 62±5 yrs.) and 15 women (50±5 yrs.) completed all of the study requirements. From the fall to winter seasons, weekly training volume was maintained (Mean±SE: 515.7±24.2 vs. 514.8±31.7 min/week, respectively), but average training HR significantly increased (117±2 vs. 123±2 bpm, respectively). Moreover, there was a significant decrease in the %T spent training <70% of APMHR and a significant increase in the %T spent training > or =70% from the fall to winter seasons (53.0±3.6% vs. 40.2±3.1% and 47.0±3.6% vs. 59.8±3.1%, respectively). Additionally, the skiers' distribution of training intensity within each season tended to follow a threshold based model, as opposed to the polarized model followed by high-level endurance athletes. While characterizing these training practices helps build the knowledge base necessary for improved coaching of this population, further observational and experimental research is warranted.Item The effects of hip angle manipulation on submaximal oxygen consumption in collegiate cyclists(Montana State University - Bozeman, College of Education, Health & Human Development, 2004) Klippel, Nathan John.; Chairperson, Graduate Committee: Daniel P. HeilThe purpose of this study was to determine the effects of hip angle (HA) manipulation on submaximal oxygen consumption (VO2SUB) in collegiate cyclists. Sixteen collegiate cyclists (Mean±SD; 23.3±3.5 years; 73.3±5.9 kg body mass; 4.54±0.34 L/min VO2MAX) were tested in five positions, each resulting in a different HA, on a cycling ergometer. The positions tested were centered around the mean HA corresponding to each cyclist's preferred position (P0), defined as the combination of trunk angle (TA) and seat tube angle (STA) in which each cyclist self-reported spending most of their time training on a bicycle. The five positions tested were the cyclist's P0 and positions resulting in mean HA's of +10°, +5°, -5°, and -10° relative to their P₀. All cyclists were tested in each of the positions at a power output corresponding to 85% of ventilatory threshold. Sagittal-view kinematics for mean HA, TA, knee angle (KA) and ankle angle (AA) were recorded to confirm that HA was the only positional measurement being manipulated. Kinematic measures confirmed that mean TA, KA, and AA were not significantly different (P>0.05).Item Determinants of skate sprint cross-country skiing performance for junior and collegiate skiers(Montana State University - Bozeman, College of Education, Health & Human Development, 2010) Willis, Sarah Jean; Chairperson, Graduate Committee: Daniel P. HeilAlthough previous research has established some correlates of sprint cross-country ski performance, it has not been determined which tests are the best determinants of sprint performance. There may be other tests or combinations of both lab- and field- based tests that are better able to determine sprint performance. PURPOSE: To investigate correlational relationships between a battery of test variables as predictors of skate roller skiing sprint performance in male and female junior and collegiate Nordic skiers. METHODS: Eleven female (Mean±SD; Age (yrs): 19±2; Height (cm): 167.6±5.5; Body Mass (kg): 64.9±7.0; Relative VO ₂MAX (ml/kg/min): 56.9±3.3) and nine male (Age (yrs): 18±1; Height (cm): 180.1±6.6; Body Mass (kg): 69.9±2.2; Relative VO ₂MAX (ml/kg/min): 70.6±4.8) competitive junior and collegiate skiers performed several lab tests including a maximal ski-striding treadmill test to exhaustion (VO ₂MAX, lactate threshold, TTE). Additional lab tests included upper body power (UBP) tests of 10 and 60 seconds, and lower body power (LBP) tests using a timing pad (1-jump, 4-jump, 60-jump vertical jump tests). Field-based roller skiing tests (40 m flying sprint, and 400 m sprint on a 200 m indoor track) were also completed. Skiers then performed a 1200 m skate roller ski sprint time trial on the indoor track. Pearson-Product Moment correlations assessed the linear relationship between all lab- and field-based variables and average race speed (m/sec) for time trial variables. Correlations were evaluated for both statistical significance (a = 0.01) and practical meaningfulness (r > or = 0.60). RESULTS: Treadmill variables correlated moderate to high with skate roller skiing sprint speed (r = 0.78 - 0.80) as did the indoor skate roller ski testing (r = 0.74 - 0.78). Recovery parameters of blood lactate measured 3 minutes post trials correlated moderately (r = 0.59 - 0.78) as well as both the UBP 10- and 60- second tests and the jump height variables of the vertical jump testing (r = 0.63 - 0.68 and r = 0.59 - 0.71). CONCLUSION: The correlations between the lab- and field-based tests and skate roller skiing sprint speed indicated that it is important to assess multiple testing methods with a variety of test durations to best determine skate sprint skiing performance.Item A comparison of training methods for enhancing climbing performance(Montana State University - Bozeman, College of Education, Health & Human Development, 2004) Davis, Colin Matthew; Chairperson, Graduate Committee: Daniel P. HeilEnhanced climbing performance may be achieved by applying systematic and documented principles to training for climbing. The purposes of this study were (a) to determine if improvements in climbing performance and related physiological variables would result from systematic training on a motorized climbing treadmill, and (b) to compare the effectiveness of two types of prescribed cardiovascular training programs on a motorized climbing treadmill: high-intensity interval training (HIT) and endurance training (ET). Climbing-related anthropometric variables, climbing performance, climbing-specific cardiorespiratory fitness, and climbing-related muscular strength and endurance were measured on 27 volunteers (13 males, 14 females) between the ages of 18 and 37 years, prior to and following six weeks of systematic physical training using a motorized climbing treadmill. Subjects were randomly assigned to training groups, which were similar with regard to gender and climbing experience. The ET program consisted of a single 20-minute bout of climbing at 65-80% of measured pre-test 2peak O for each workout session,; the HIT program consisted of three 6-minute bouts of climbing at 80-95% of measured pre-test 2peak O V & , separated by three minutes of standing rest, for each workout session. Following training, climbing performance tended to be higher as a result of the HIT program compared to the ET program (p = 0.069), while climbing performance was significantly improved following training as a result of either program. Climbing-specific cardiorespiratory fitness did not differ between groups following training. With the exception of hand-grip strength, climbing-related muscular strength and endurance were significantly higher following training, with no differences observed between groups. Small yet significant improvements in climbing-related anthropometric variables were observed following training in both groups with no differences between groups. The results of this study show that six weeks of systematic physical training using a motorized climbing treadmill is capable of improving climbing performance, climbing-related strength and endurance, and climbing-related anthropometric variables. It was concluded that systematic training on a motorized climbing treadmill can be an effective method of increasing climbing-specific fitness and improving climbing performance.
