The Relationship Between Gluteus Maximus Activation And Running Economy In Recreational Distance Runners, Carlos Hernandez Jan 2023

The Relationship Between Gluteus Maximus Activation And Running Economy In Recreational Distance Runners, Carlos Hernandez

Cal Poly Humboldt theses and projects

Within the running community, there are strategies that a trainer will utilize to improve the performance of an athlete. One of these strategies suggests that an increase in activation of the Gluteus Maximus (GM) muscle will result in an increase in the efficiency of runners. The primary purpose of this study is to examine the relationship between GM activation and running economy (RE).

Methods: Three female and seven male recreational runners (27±8 yrs) from California Polytechnic State University, Humboldt and the local community. A Pearson product-correlation was used to determine the strength of the relationship between Gluteus Maximus activation and …

Longitudinal Sport Science Implementation In American Collegiate Men’S Basketball, Jason Stone

Graduate Theses, Dissertations, and Problem Reports (ETD)

The expanding opportunities to implement sport science frameworks in elite-level basketball environments coincide with the sport’s increasing global prominence. Concomitant to these opportunities is the continual growth of the sport technology market (e.g., wearables, force plates) and computational power (e.g., data management tools, coding capabilities), which yields solutions and challenges for both athletes and practitioners. Due to the rapid influx of new sport technologies in high performance environments, particularly American Collegiate Men’s Basketball, more formal and ecologically valid research on how to effectively utilize data derived from them, particularly over long periods of time (i.e., multiple seasons) is needed. To …

The lateral jump task involved the subject beginning by standing on the force plate and jumping sideways off one foot and then landing on the floor …


Does Fatigue Influence Joint-Specific Work And Ground Force Production During The First Steps Of Maximal Acceleration?, Shayne Vial, Jodie C. Wilkie, Mitchell Turner, Mark Scanlan, Anthony J. Blazevich Jan 2023

Does Fatigue Influence Joint-Specific Work And Ground Force Production During The First Steps Of Maximal Acceleration?, Shayne Vial, Jodie C. Wilkie, Mitchell Turner, Mark Scanlan, Anthony J. Blazevich

Research outputs 2022 to 2026

During initial acceleration, the first steps of a maximal-effort (sprint) run often determine success or failure in the capture and evasion of an opponent, and is therefore a vital factor of success in many modern sports. However, accelerative events are commonly performed after having already run considerable distances, and the associated fatigue should impair muscle force production and thus reduce acceleration. Despite this, the effects of running-induced fatigue on our ability to accelerate as well as the running technique used to achieve it have received little attention. We recorded 3-D kinematics and ground reaction forces during the first three steps …

The Impact Of Acute Calcium Intake On Bone Turnover Markers During A Training Day In Elite Male Rowers, Bronwen Lundy, Alannah K. A. Mckay, Nikita C. Fensham, Fensham, Nicolin Tee, Bryce Anderson, Aimee Morabito, Megan L. R. Ross, Marc Sim, Kathryn Ackerman, Louise M. Burke

Research outputs 2022 to 2026

Introduction: While an acute exercise session typically increases bone turnover markers (BTM), the impact of subsequent sessions and the interaction with pre-exercise calcium intake remains unclear despite the application to the ‘real life’ training of many competitive athletes. Methods: Using a randomized crossover design, elite male rowers (n = 16) completed two trials, a week apart, consisting of two 90-minute rowing ergometer sessions (Ex1, Ex2) separated by 150 minutes. Prior to each trial, participants consumed a high (CAL: ~1000 mg) or isocaloric low (CON: < 10 mg) calcium meal. Biochemical markers including parathyroid hormone: PTH; serum ionised calcium (iCa) and bone turnover markers (C-terminal telopeptide of type I collagen: β-CTX-I; osteocalcin: OC) were monitored from baseline to 3 hours post Ex2. Results: While each session caused perturbances of serum iCa, CAL maintained calcium concentrations above those of CON for most time points, 4.5 and 2.4 % higher post EX1 and EX2 respectively. The decrease in iCa in CON was associated with an elevation of blood PTH (p < 0.05) and β-CTX-I (p < 0.0001) over this period of repeated training sessions and their recovery, particularly during and after Ex2. Pre-exercise intake of calcium-rich foods lowered BTM over the course of a day with several training sessions. Conclusions: Pre-exercise intake of a calcium-rich meal prior to training sessions undertaken within the same day had a cumulative and prolonged effect on the stabilisation of blood iCa during exercise. In turn, this reduced the post-exercise PTH response, potentially attenuating the increase in markers of bone resorption. Such practical strategies may be integrated into the athlete’s overall sports nutrition plan, with the potential to safeguard long term bone health and reduce the risk of bone stress injuries.

Fatigue Does Not Increase Limb Asymmetry Or Induce Proximal Joint Power Shift In Habitual, Multi-Speed Runners, Shayne Vial, Jodie Cochrane Wilkie, Mitchell Turner, Anthony J. Blazevich Jan 2023

Fatigue Does Not Increase Limb Asymmetry Or Induce Proximal Joint Power Shift In Habitual, Multi-Speed Runners, Shayne Vial, Jodie Cochrane Wilkie, Mitchell Turner, Anthony J. Blazevich

Research outputs 2022 to 2026

During prolonged jogging, joint moment and work tend to decrease in the distal (ankle) joint but increase at proximal (hip/knee) joints as performance fatigue manifests, and such adaptations might be expected to occur in sprinting. Fatigue is also thought to increase inter-limb asymmetries, which is speculated to influence injury risk. However, the effects of fatigue on sprint running gait have been incompletely studied, so these hypotheses remain untested. Using statistical parametric mapping, we compared 3-D kinematics and ground reaction force production between the dominant (DL) and non-dominant (NDL) legs of 13 soccer players during both non-fatigued and fatigued sprint running. …

Sprint Cycling Rate Of Torque Development Associates With Strength Measurement In Trained Cyclists, Shannon Connolly, Peter Peeling, Martyn J. Binnie, Paul S. R. Goods, Christopher Latella, Janet L. Taylor, Anthony J. Blazevich, Wouter P. Timmerman, Chris R. Abbiss

Research outputs 2022 to 2026

Purpose:

A cyclist’s rate of force/torque development (RFD/RTD) and peak force/torque can be measured during single-joint or whole-body isometric tests, or during cycling. However, there is limited understanding of the relationship between these measures, and of the mechanisms that contribute to each measure. Therefore, we examined the: (i) relationship between quadriceps central and peripheral neuromuscular function with RFD/RTD in isometric knee extension, isometric mid-thigh pull (IMTP), and sprint cycling; and (ii) relationship among RFD/RTD and peak force/torque between protocols.

Methods:

Eighteen trained cyclists completed two familiarisation and two experimental sessions. Each session involved an isometric knee extension, IMTP, and sprint …

Research outputs 2022 to 2026

Increasing muscle strength and cross-sectional area is of crucial importance to improve or maintain physical function in musculoskeletal rehabilitation and sports performance. Decreases in muscular performance are experienced in phases of reduced physical activity or immobilization. These decrements highlight the need for alternative, easily accessible training regimens for a sedentary population to improve rehabilitation and injury prevention routines. Commonly, muscle hypertrophy and strength increases are associated with resistance training, typically performed in a training facility. Mechanical tension, which is usually induced with resistance machines and devices, is known to be an important factor that stimulates the underlying signaling pathways to …

Human In Vivo Medial Gastrocnemius Gear During Active And Passive Muscle Lengthening: Effect Of Inconsistent Methods And Nomenclature On Data Interpretation, Matheus Daros Pinto, Kazunori Nosaka, James M. Wakeling, Anthony J. Blazevich

Research outputs 2022 to 2026

‘Muscle gear’ is calculated as the ratio of fascicle-to-muscle length change, strain, or velocity. Inconsistencies in nomenclature and definitions of gear exist across disciplines partly due to differences in fascicle [curved (Lf) versus linear (Lf,straight)] and muscle [whole-muscle belly (Lb) versus belly segment (Lb,segment)] length calculation methods. We tested whether these differences affect gear magnitude during passive and active muscle lengthening of human medial gastrocnemius of young men (n=13, 26.3±5.0 years) using an isokinetic dynamometer. Lb, Lb,segment, Lf and Lf,straight were measured from motion analysis and ultrasound imaging data. Downshifts in belly gear but not belly segment gear occurred with …

Training Specificity And Functional Performance In Collegiate Cheerleaders, Carly Routman Jan 2023

Training Specificity And Functional Performance In Collegiate Cheerleaders, Carly Routman

College of Graduate Studies: Theses & Dissertations

INTRODUCTION: Competitive collegiate cheerleading requires participants to be conditioned for explosive powerful movements. Studies have shown cheerleading is associated with a high incidence of catastrophic injury (Mueller, 2009; Boden, 2005; Xu et al., 2021). In response to high injury rates, studies have recommended strength and conditioning requirements to decrease the likelihood of injury due to the lack of cheer-specific training (Jacobson et al., 2004). Although it has been recommended for cheerleaders to receive formal strength training, many schools do not provide these resources to their cheerleading teams. PURPOSE: The purpose of this study was to determine if there are differences …

Timing Is Everything, But Does It Really Matter? Impact Of 8-Weeks Morning Versus Evening Iron Supplementation In Ballet And Contemporary Dancers, Caitlin Attwell, Alannah Mckay, Marc Sim, Cory Dugan, Joanna Nicholas, Luke Hopper, Peter Peeling Jan 2023

Timing Is Everything, But Does It Really Matter? Impact Of 8-Weeks Morning Versus Evening Iron Supplementation In Ballet And Contemporary Dancers, Caitlin Attwell, Alannah Mckay, Marc Sim, Cory Dugan, Joanna Nicholas, Luke Hopper, Peter Peeling

Research outputs 2022 to 2026

The effectiveness of a morning versus evening oral iron supplement strategy to increase iron stores was explored. Ballet and contemporary dancers with serum ferritin (sFer) < 50 g/L (n = 14), were supplemented daily with 105 mg elemental oral iron in either the morning (FeAM) or evening (FePM) for 8 weeks. A control group (n = 6) with sFer > 50 g/L were given no supplement over the same period. Dancers’ sFer were measured at baseline and post-intervention. Assessment of daily training load, dietary intake, and menstruation were made. A significant interaction (p < 0.001) showed the within group sFer change over the 8-week intervention in FeAM (+25.9 ± 10.5 g/L) and FePM, (+22.3 ± 13.6 g/L) was significantly different to CON (−30.17 ± 28.7 g/L; both p = 0.001). This change was not different between FeAM and FePM (p = 0.778). sFer levels within FeAM and FePM significantly increased over the 8-weeks; however, they significantly decreased in the CON group (all p < 0.05). Post-intervention sFer levels were no longer different between the three groups (p > 0.05). Training load, dietary intake, and number of menstrual cycles incurred were similar between FeAM and FePM (p > 0.05). Oral iron supplementation in either the morning or evening appears equally effective in increasing sFer levels in dancers with sub-optimal iron status.

Effects Of Submaximal And Supramaximal Accentuated Eccentric Loading On Mass And Function, Sergio Maroto-Izquierdo, Fernando Martín-Rivera, Kazunori Nosaka, Marco Beato, Javier González-Gallego, José A. De Paz

Research outputs 2022 to 2026

Introduction: Eccentric-overload (EO) resistance training emerges as an alternative to more optimally prescribe intensity relative to the force generation capabilities of the eccentric muscle contraction. Given the difficulties to individually prescribe absolute eccentric loads relative to each person’s eccentric ability, setting the load relative to the concentric one-repetition maximum (1-RM) is the most used EO training approach. Therefore, we investigated the effects of submaximal and supramaximal (i.e., eccentric loads above 100% of 1-RM) accentuated eccentric training on changes in lean mass, anabolic hormonal responses and muscle function. Methods: Physically active university students (n = 27) were randomly assigned to two …

Research outputs 2022 to 2026

Unequal proportions of male and female participants in exercise research might be attributed, in part, to differences in interest and willingness to participate. We tested if men and women are equally interested and willing to undergo exercise research procedures and if they consider different factors when deciding to participate. Two samples completed an online survey. Sample 1 (129 men, 227 women) responded to advertisements on social media and survey-sharing websites. Sample 2 (155 men, 504 women) was comprised of undergraduate psychology students. In both samples, men were significantly more interested to learn their muscle mass amount, running speed, jump height, …

Objective. Exercise has been shown to be an effective intervention; the difficulty still lies in providing exercise programs to the older adults in rural areas. Therefore, this study aimed to examine the effects of a 12-week exercise program provided with visual guidelines (prerecorded video) on frailty among older adults in rural areas. Methods. Fifty participants (71.7 ± 4.9 years) from 5 different rural areas were recruited and divided into two groups: the exercise group (EX, n = 24 (male: 8, female: 18)) and the control group (CON, n = 26 (male: 7, female: 17)). With the commencement of the exercise …
