Rodeo: Sparse Nonparametric Regression in High Dimensions

We present a greedy method for simultaneously performing local bandwidth selection and variable selection in nonparametric regression. The method starts with a local linear estimator with large bandwidths, and incrementally decreases the bandwidth of variables for which the gradient of the estimator with respect to bandwidth is large. The method--called rodeo (regularization of derivative expectation operator)--conducts a sequence of hypothesis tests to threshold derivatives, and is easy to implement. Under certain assumptions on the regression function and sampling density, it is shown that the rodeo applied to local linear smoothing avoids the curse of dimensionality, achieving near optimal minimax rates of convergence in the number of relevant variables, as if these variables were isolated in advance

A Pilot Study Investigating the Effects of the Summer Rodeo Season on Functional Movement Screening Scores of College Rodeo Athletes

Rodeo is well known for its high-velocity, high-impact atmosphere where athletes compete against the clock and uncooperative livestock. Many rodeo competitive related injuries are associated with insufficient muscular synergy, endurance, strength, and limb flexibility. PURPOSE: The purpose of this investigation was to examine the difference between pre-summer rodeo functional movement screening (FMS) outcomes and post-summer rodeo FMS outcomes of rodeo athletes. METHODS: The researchers conducted pre-summer rodeo FMS assessments on collegiate rodeo athletes (n = 8). Athletes were instructed to complete their standard summer rodeo season without the integration of exercise modalities that may serve as corrective strategies for altered functional movement onset by the demands of rodeo performance. Rodeo athletes returned for post-summer rodeo season FMS testing upon the conclusion of their summer rodeo season. A paired-sample t-test (p \u3c 0.05) was employed to identify differences in pre- and post-summer rodeo FMS outcomes. RESULTS: The statistical analysis revealed no significant differences between pre- and post-summer rodeo season FMS scores. However, moderate effects sizes were identified between pre- and post-rotary stability (d = .725), pre- and post-deep squat (d = .725), and pre- and post-hurdle step (d = .725), and pre- and post-trunk stability (d = -.540). CONCLUSION: These results suggest that the intensity and volume of summer rodeo season performance may contribute to alterations in rodeo athlete’s functional movement abilities. An FMS utilized to identify movement compensations/limitation of rodeo athletes prior to summer rodeo season, and the integration of exercise modalities that serve as corrective strategies for the presented movement compensations may assist in decreasing the chance of non-impact injury sustainmen

Book Review: College Rodeo: From Show to Sport

Clearly, college rodeo has meant much to the life of Sylvia Gann Mahoney. She was a college rodeo coach herself. She married a rodeo coach. She is a founder of an intercollegiate Rodeo alumni group. Perhaps her close association with college rodeo and her obvious love for the sport is the reason she should not have written this book

Differences in Functional Movement Screening Score between College Rodeo Events

The sport of rodeo is recognized as a high velocity/intensity activity, with a wide range of varying dynamic movements occurring across difference rodeo events. High velocities and extreme dynamic range of motion movements, compound with uncooperative livestock, contribute to elevated risk of injury. While these factors generally attribute to rodeo injuries, little is known in regards to movement limitations of rodeo athletes. PURPOSE: Therefore, the purpose of the current investigation was to identify movement pattern differences among rodeo events using the Functional Movement Screening (FMS) test. METHODS: College rodeo athletes (n = 85) from a mid-size university in the southwest region were selected as participants for this study. Athletes were categories according to their respected rodeo event: Steer Wrestling (n = 7), Breakaway Roping (n = 28), Goat Tying (n = 11), Barrel Racing (n = 20), Saddle Bronc Riding (n = 9), Tie Down Roping (n = 4), Bull Riding (n = 2), or Team Roping (n = 4). Following, all rodeo athletes completed an FMS test to establish movement efficiencies. A MANOVA was utilized to differentiate FMS scores between rodeo events. RESULTS: There was a statistically significant main effect between rodeo event and FMS outcomes of rodeo athletes, F(56, 382.72) = 1.777, p = .001; Wilk’s Λ = .288, partial η2 = .163. LSD Post hoc test revealed significant differences between various events for all dependent variables except the Hurdle Step Test. CONCLUSION: These results suggest different rodeo event specific movement pattern may affect FMS test results. Additionally, for the practitioner, these differences may serve as valid precursors to injuries per rodeo event

Differences in Simple and Complex Reaction Time Test Score Amont College Rodeo Athletes

Various sports rely heavily on reaction time (RT) to produce high levels of performance, and as expected, difference in RT are present within and between sporting activities. The sport of rodeo is a high velocity/intensity sport that require athletes to reaction quickly to the movement(s) of uncooperative livestock. However, no previous studies have investigated the RT profile of rodeo athletes and the differences in RT between rodeo events. PURPOSE: The purpose of this investigation was to establish simply and complex RT norms for rodeo athletes and secondly, identify RT difference between rodeo events. METHODS: College rodeo athletes (n = 39) from a mid-sized university in the southwest region volunteered as participates in this study. The athletes were categorized according to their rodeo event: Steer Wrestling (n = 3), Roping (n = 15), Goat Tying (n = 6), Barrel Racing (n = 10), or Rough Stock (n = 5). All rodeo athletes completed two RT tests, simple RT test (sRT) and complex RT test (cRT), which yielded RT measures for average sRT response, average cRT response, total sRT, and total cRT. These RT metrics were utilized to establish rodeo RT norms and describe differences among rodeo events. Basic descriptive statistics were calculated to establish rodeo RT norms and secondly, a MANOVA was utilized to differentiate reaction time scores between rodeo events. RESULTS: There were no significant difference between Steer Wrestling (sRT Ave. Total 30.52±2.95; cRT Ave. Total 34.21±2.70), Ropers (sRT Ave. Total 32.29±4.25; cRT Ave. Total 35.70±4.56), Goat Tying (sRT Ave. Total 32.42±1.74l; cRT Ave. Total 38.3±5.47), Barrel Racing (sRT Ave. Total 32.77±3.45; cRT Ave. Total 35.29±2.46), and Rough Stock (sRT Ave. Total 32.12±3.45; cRT Ave. Total 35.32±4.14) for all reaction time measures. CONCLUSION: The results of the investigation indicated RT performance were similar among all rodeo events. These results additionally provide newly established RT norms for rodeo athletes that could be utilized as baseline target metrics for RT training

Physical Therapy Management of Rodeo Injuries

The sport of rodeo is a high risk event. Each event presents unique dangers creating opportunity for injury. The high injury rate calls for medical intervention for these athletes. However, there are a limited number of publications and research relative to medical care for rodeo athletes. The purpose of this paper is to inform physical therapists about the sport of rodeo, its members, mode of injury and atmosphere surrounding this sport. By increasing awareness, physical therapists will have a better understanding of rodeo and the special challenges it presents. Several key points will be discussed. The history of rodeo, as well as the history of medical care, will be outlined. Next, high risk rodeo events will be described, the mechanism of injury examined and common injuries identified. Finally, physical therapy intervention will be assessed. Physical therapists should be aware of the special needs of rodeo athletes in order to treat them effectively. By understanding the mechanism of injury, the cowboy\u27s lifestyle and the physical demands needed to return to the sport, the physical therapist and rodeo athlete will have common goals creating a successful outcome

Campus Cowboys and Cowgirls: A Research Note on College Rodeo Athletes

College rodeo has evolved from small, single-campus fund-raisers, celebrations, and/or competitions into an internationally recognized North American collegiate sport. Throughout its history, though, the sport has received virtually no attention in the sociological literature. In this research note I provide a descriptive summary of member characteristics and selected findings from a 2003-2004 National Intercollegiate Rodeo Association membership survey. I also empirically examine the association of size of place of residency during childhood with previous involvement in rodeo (i.e., before participating in college rodeo). Findings reveal that respondents who spent most of their childhood in more rural areas (i.e., in the countryside outside any city or town) have participated in rodeo (or rodeo-related events), on average, for more years than those who primarily resided in more urban locales (i.e., a city of 50,000 or more) during childhood
