Moreno, Fabrice G. Risso, Tricia M. Liu, Alyssa A. Stage, Samantha A. Birmingham-Babauta, John J. Stokes, Dominic V. Giuliano, Adrina Lazar, Deshaun L. Davis, Ashley J. Orjajo

Research outputs 2014 to 2021

The close-grip bench press (CGBP) is a variation of the traditional bench press (TBP) that uses a narrower grip (~95% of biacromial distance (BAD)) and has potential application for athletes performing explosive arm actions from positions where the hands are held close to the torso. Limited research has investigated CGBP mechanics compared to the TBP. Twenty-seven resistance-trained individuals completed a one-repetition maximum TBP and CGBP. The TBP was performed with the preferred grip; the CGBP with a grip width of 95% BAD. A linear position transducer measured lift distance and duration; peak and mean power, velocity, and force; distance and …

Current Research And Statistical Practices In Sport Science And A Need For Change, Jake R. Bernards, Kimitake Sato, G. Gregory Haff, Caleb D. Bazyler

Research outputs 2014 to 2021

Current research ideologies in sport science allow for the possibility of investigators producing statistically significant results to help fit the outcome into a predetermined theory. Additionally, under the current Neyman-Pearson statistical structure, some argue that null hypothesis significant testing (NHST) under the frequentist approach is flawed, regardless. For example, a p-value is unable to measure the probability that the studied hypothesis is true, unable to measure the size of an effect or the importance of a result, and unable to provide a good measure of evidence regarding a model or hypothesis. Many of these downfalls are key questions researchers strive …

Are Rolling Averages A Good Way To Assess Training Load For Injury Prevention?, Paolo Mensaspa

Research outputs 2014 to 2021

I read the letter ‘Time to bin the term ‘overuse’ injury: is ‘training load error’ a more accurate term?’ with great interest.1 I agree with the authors that changes in training load (TL) could increase injury risk and I share their concern relating to periods of low/no loads. However, the terminology suggested by Drew and Purdam ‘errors in training load prescription’ may not be ideal. In fact, despite the potentially flawless TL prescription, some spikes in load may be due to variables that are out of control, such as variability in the demands of competitions,2 and cannot be avoided. Moreover, …

The Effect Of Personal Protective Equipment On Firefighter Occupational Performance, Ashley Y. Lesniak

Theses and Dissertations--Kinesiology and Health Promotion

Firefighting is a strenuous occupation that requires high-intensity work, resulting in prolonged periods of stress and physical exertion. The physical demand of performing firefighting tasks is augmented by the weight of personal protective equipment (PPE) worn (i.e., load carriage: LC) and the use of a self-contained breathing apparatus (SCBA). These factors have been shown to increase metabolic demand at submaximal workloads and decrease maximal aerobic capacity in laboratory settings. However, there is limited research evaluating the effects of these factors on occupational performance. Therefore, the primary purpose of this study was to quantify the detrimental effect of LC only and …

The Effects Of Oral Curcumin And Bioperine Supplementation On C - Reactive Protein In Crossfit Athletes, Bailey Franzen, Cassandra Greenawalt, Sloan Vlahos

Loma Linda University Research Reports

PURPOSE. C-reactive protein (CRP) is an acute-phase inflammatory marker which circulates in blood plasma and rises in the presence of systemic inflammation. Strenuous exercise, such as that performed by CrossFit athletes, has been found to acutely raise CRP levels. Curcumin has demonstrated the ability to reduce CRP levels by blunting the release of pro-inflammatory cytokines secondary to the suppression of the NF- κB pathway. Concomitant graduate research administration of bioperine with curcumin improves bioavailability by 2,000%. The aim of this study was to evaluate the effects of oral curcumin and bioperine supplementation on CRP levels in CrossFit athletes. METHODS. Sixteen …

Reviewing The Use Of Injury Screening Assessments And Identifying Risk Of Injury, Riley A. Kenney

Graduate Student Theses, Dissertations, & Professional Papers

Lower extremity injures account for over half of reported sports related injuries with the ankle and knee being the most commonly injured joints. The majority of non-contact injuries related to these two joints can potentially be prevented through individualized prevention programs. Biomechanical injury screening has the potential to identify the risk factors associated with injury and allows the implementation of targeted rehabilitation strategies to combat the identified deficits. There is substantial need for screening assessments that are practical and accurate for the clinical athletic trainer. This literature reviewed examined the dorsiflexion lunge test, Functional Movement Screen (FMS), Y-Balance Test, Star …

Graduate Student Theses, Dissertations, & Professional Papers

Throwing injuries in baseball are increasing amongst major league baseball pitchers. Injuries to the shoulder complex and elbow ligamentous structures are increasing. Variables including pitch count, pitch type, throwing style, and duration of the game have all been “linked” to potential injury. Noticing the realtionship between these variables and injuries can lead to an upward trend in the decrease of throwing injuries.

Association Between Energy Balance And Metabolic Hormone Suppression During Ultra-Endurance Exercise, Bjoern Geesmann, Jenna C. Gibbs, Joachim Mester, Karsten Koehler

Department of Nutrition and Health Sciences: Faculty Publications

Ultra-endurance athletes often accumulate an energy deficit when engaging in ultra-endurance exercise, and upon completion of the exercise, they exhibit endocrine changes that are reminiscent of starvation. However, it remains unclear whether these endocrine changes are a result of the exercise per se or secondary to the energy deficit, and more importantly, whether these changes can be attenuated by increased dietary intake. Our goal was to assess the relationship between changes in key metabolic hormones following ultra-endurance exercise and measures of energy balance. Metabolic hormones as well as energy intake and expenditure were assessed in 14 well-trained male cyclists who …

Effects Of Active Versus Passive Recovery On Blood Lactate And Performance In Repeated Wingate Tests, Madison Kirkpatrick

Cal Poly Humboldt theses and projects

The purpose of this study is to determine if an active recovery of a long duration at a moderate intensity or a passive recovery is more beneficial for subsequent anaerobic performance by tracking blood lactate and comparing anaerobic performance variables across Wingate tests. Currently, there is a lack of research on the effect of a longer duration active recovery protocol on blood lactate levels and power output in repeated Wingate tests as compared to passive recovery. A significant interaction was found between recovery and time for blood lactate (F = 6.935; p = 0.000). Blood Lactate levels were significantly …

Restoration Of Attentional Deficits After Concussion, Katharine B. Earle

Cal Poly Humboldt theses and projects

Difficulties with concentration and attention are among the most prevalent symptoms experienced after concussion. Rest has been the most common form of recovery from concussion; however, new research is suggesting mild mental exertion to be an effective aid in recovery. Drawing from Attention Restoration Theory, this study evaluated the idea that cognitive engagement with natural environments can mitigate post-concussion directed-attention deficits. A between subjects repeated measures design was used to test directed-attention after video exposure to restorative/nature and nonrestorative/city environments. Measures of mood, connectedness to environment, and symptomology scores were also collected. No meaningful difference between exposure type was found …

Retrospective Analysis Of Contact Sport Participation On Cognitive Function In Healthy Athletes, Lisa C. Martinez

Cal Poly Humboldt theses and projects

This study explored the effects of contact and limited contact sport participation on neurocognitive function in non-concussed collegiate and adolescent athletes over time. Athletes participating in contact and limited contact sports have an increased risk of sustaining neurocognitive injuries, known as subconcussive blows, compared to non-contact sport athletes. We hypothesized that athletes participating in contact and limited contact sports, would exhibit a deficit in neurocognitive function following multiple seasons of play when compared to athletes participating in non-contact sports. Using a mixed repeated measures MANOVA statistical design, we analyzed computerized neurocognitive baseline ImPACT composite scores (verbal memory, visual memory, visual …

The Effects Of Augmented Feedback On Pacing And Performance Of Elite Combat Athletes, Israel Halperin

Theses: Doctorates and Masters

Augmented feedback has been shown to improve performance and influence pacing in various physical activities. However, few studies have investigated its effects on performance and pacing in striking combat sports. Additionally, despite the plethora of studies examining the influence of feedback in untrained individuals, there is a lack of research examining the effects of such feedback in trained participants. Considering the important role of feedback in training and competition, the purpose of this thesis is to examine the effects of three different but inter-dependent methods of augmented feedback on performance of combat, and resistance trained athletes.

Study 1 examined the …
