Reliability Of A Barre-Mounted Dynamometer-Stabilizing Device In Measuring Dance-Specific Muscle Performance, Melissa Strzelinksi, Lori Thein Brody, Jo Armour Smith, Shaw Bronner

Physical Therapy Faculty Articles and Research

BACKGROUND: Hand-held dynamometry is considered an efficient, effective, and portable means of objectively measuring lower extremity strength; however, it has yet to be studied specific to dance-relevant muscle performance. Also, dynamometry is often criticized for variability in results based on tester strength and sex. Use of an external stabilizing device has been suggested to minimize differences in outcomes between male and female testers by reducing variability associated with tester strength limitations. Therefore, this study used a barre-mounted, portable dynamometer stabilizing device to improve consistency of results among different testers for assessing hip and lower extremity muscle performance in dance-relevant positions. …

Associations Between Maternal Technology Use, Perceptions Of Infant Temperament, And Indicators Of Mother-To-Infant Attachment Quality, Shawnee Alvarez Guitierrez, Alison K. Ventura

Health And Ergogenic Potential Of Oral Adenosine-5′-Triphosphate (Atp) Supplementation, Ralf Jäger, Martin Purpura, John A. Rathmacher, John C. Fuller Jr., Lisa M. Pitchford, Fabricio E. Ross, Chad M. Kerksick

Faculty Scholarship

Adenosine triphosphate (ATP) is the primary compound that provides energy to drive many processes in living cells, including muscle contraction, neurotransmission, and cardiac function. Initial research used enteric-coated ATP that displayed no apparent efficacy. However, ATP disodium supplementation has demonstrated improved bioavailability and acute and chronic benefits to cardiovascular health, muscular performance, body composition, and recovery while attenuating muscle breakdown and fatigue. In this review, we provide a critical assessment of oral ATP’s bioavailability and its various health and ergogenic benefits.

Different Cooling Strategies Applied During Inter-Set Rest Intervals In High-Intensity Resistance Training, Gilmar J. Esteves, Renato A. Garcia, Paulo H. S. M. Azevedo

International Journal of Exercise Science

International Journal of Exercise Science 14(2): 295-303, 2021. The purpose of this study was to verify whether cooling between sets during high-intensity resistance exercise improves physical performance and to compare performance among different sites of cooling. It is important because delaying the muscular fatigue could improve total volume at a training session which could lead to greater hypertrophy. Nine healthy and recreational resistance training experienced men, performed six tests of a biceps curl exercise on different days. The first test was the one-repetition maximum test (1RM). Following, we applied five sessions, in crossover and randomized (counter-balanced) design. The subjects received …

Da Costa, Kelly Samara Silva

Faculty Publications

Schools have been the main context for physical activity (PA) and sedentary behavior (SB) interventions among adolescents, but there is inconsistent evidence on whether they also improve dimensions of the health−related quality of life (HRQoL). The aim of this study was to evaluate the effects of a school-based active lifestyle intervention on dimensions of HRQoL. A secondary aim was to verify whether sex, age, and HRQoL at baseline were moderators of the intervention effect. A cluster-randomized controlled trial was conducted at three control and three intervention schools in Florianopolis, Brazil. All students from 7th to 9th grade were invited to …

Getting In: Safe Water Entry Competencies, Kevin Moran Dr, Jennifer Blitvich, Lauren Petrass, Keith Mcelroy

International Journal of Aquatic Research and Education

In high income countries, jumping and diving into water are a small but persistent cause of death and serious injury especially among male youth and young adults. Although water entries maintain a high media profile, little is known about what entry competencies and underlying water safety knowledge youth bring to this practice. Undergraduates enrolled in aquatics (N= 76) completed a survey before attempting 7 entry jumping and diving tasks. While safety attitudes and self-reported behaviours were generally good, considerable variation in practical entry competence was evident. Most completed a deep-water compact jump (87%) and PFD jump (88%) with …

Perceptions Of Water Competencies, Drowning Risk And Aquatic Participation Among Older Adults, Teresa Stanley, Kevin Moran

International Journal of Aquatic Research and Education

New Zealand has an aging population and, despite falling drowning tolls in all other age groups (WSNZ, 2019c), older adults have continued to drown in both increasing numbers and proportion. The reasons for this are not well understood since very little drowning research has focused on older people. A water safety survey (N = 389) seeking information on older adults’ aquatic recreational practices and perceptions of safety was conducted at the end of the summer season, 2019. Most adults (86%, n = 335) reported some aquatic activity in the previous year, but those aged 65+ years (66%) were significantly …

Water Safety Education Programs In Culturally And Linguistically Diverse Seattle Communities: Program Design And Pilot Evaluation, William A. Koon, Elizabeth Bennett, Sarah Stempski, Jennifer Blitvich

International Journal of Aquatic Research and Education

Drowning is a public health concern that disproportionally affects children and minorities in Washington State. Community health educators from Seattle Children’s Hospital designed a Water Safety Education and Lifejacket Giveaway Program for low-income parents of preschool-aged children from culturally and linguistically diverse backgrounds. The program was interpreted into multiple languages and parents and children in attendance received free lifejackets. The mixed-methods pilot evaluation of this program found statistically significant relationships between language and self-reported parent swim skill level (English-speaker OR 4.6; 95%CI: 1.84 – 11.54); and confidence of keeping one’s child safe (English-speaker OR 3.34; 95%CI: 1.10 – 10.4). Additionally, …

Surfboard Paddling Technique And Neuromechanical Control: A Narrative Review, Wynand Volschenk, Zachary J. Crowley-Mchattan, John W. Whitting, Rudi A. Meir, Alec K. Mckenzie

International Journal of Aquatic Research and Education

Surfboard paddling is an essential activity when surfing. Research investigating surfboard paddling, especially as it pertains to neuromechanical control and techniques used, is limited. Previous research made use of swim ergometers to examine surfboard paddling demands. The validity of using swim ergometers in surfboard paddling research and training deserves further analysis. To establish ecologically valid findings, researchers have begun to use swim flumes and still-water paddling environments to investigate paddling efficiency and technique. This emerging body of research has reported that muscle activation patterns, intensities, and timings differ as surfers move through different paddle stroke phases. A deeper understanding of …
