Nitrate-rich beetroot juice (BR) supplementation improves movements with high-velocity and high-power muscle contractions which may be due to enhanced blood flow, oxygenation and contractile function in type II muscle fibers. The literature has focused predominantly on the effects of BR supplementation running and cycling performance, but its efficacy in resistance exercise, a modality that relies on type II muscle fibers, has limited data. Furthermore, it is unknown how supplementation strategies impact the physiological and ergogenic effects of BR during exercise. Therefore, the purpose of this study is to assess whether single or multi-day nitrate ingestion will improve performance and muscle …

The Effect Of Co-Ingesting Beetroot Juice And Vitamin C On Blood Pressure In Hispanic Women: A Literature Review And A Proposal, Mikela De La Flor, Maya Hammer, Noelle Seekamp-Hicks, Rachel Tan

Seaver College Research And Scholarly Achievement Symposium

Dietary nitrate supplementation is known for improving blood pressure through vasodilation and may favorably alter oral microbial populations related to cardiovascular health. Co-ingestion with vitamin C (VITC) may further potentiate these benefits but this remains unexplored. Additionally, this field has yet to examine the influence of sex and ethnicity, which is important given that physiological differences exist between populations. The purpose of this study is to assess the effects of combining dietary nitrate, in the form of beetroot juice, and VITC on blood pressure and the oral microbiome in women of Hispanic, African American, and American descent across multiple institutions. …

Developing A Dental Trauma-Anxiety Measure Comparing U.S. And International Care, Margaret Tajirian

Seaver College Research And Scholarly Achievement Symposium

Background

The aim of this study was to improve upon the Modified Dental Anxiety Scale (MDAS) by developing the empathy-based International-Modified Dental Anxiety Scale (I-MDAS). This measure was produced and utilized to compare the dental experiences and anxiety levels of international patients versus national patients in the United States.

Methods

The I-MDAS is composed of the International scale and the original MDAS scale. Of 465 participants, 41.3% comprised the national population and 58.7% comprised the international population. Information about demographics, past negative dental experiences, and current dental anxiety was collected.

Results

There was no significant difference in dental anxiety levels …

Pomegranate Extract Supplementation On Neuromuscular Performance During Resistance Exercise, Katie Price, Joanna Powell, Matthew Joyner, Adam Pennell, Rachel Tan

Seaver College Research And Scholarly Achievement Symposium

Dietary nitrate supplementation has been shown to improve skeletal muscle function during high-velocity and high-power contractions due to its high nitrate levels; however, there is limited data examining its potential in exercise requiring these movements, such as resistance exercise. Nitrate supplementation has been studied extensively as beetroot juice, but its poor taste severely limits its application. Pomegranate extract (POM) may be an alternative nitrate source due to its superior taste, high nitrate content, and additional antioxidants but has yet to be explored. The purpose of the present study is two-fold: 1) to determine the nitrate concentration in POM; and 2) …

The Effects Of Acute Beetroot Juice Ingestion On Upper And Lower Body Muscular Power During Weightlifting Exercise In Men., Sean Karl, Isabella Lincoln, Joanna Powell, Grant Weiderman, Katie Price, Lauren Wideen, Andrew Fest, Justin Kim, Maya Hammer, Noelle Seekamp-Hicks, Joshua Leow, Maddy Espinoza, Adam Pennell, Rachel Tan

Seaver College Research And Scholarly Achievement Symposium

Dietary nitrate supplementation, administered per beetroot juice (BR), has been shown to enhance performance while cycling and running. BR has enhanced skeletal muscle contraction and blood flow within type II fibers which are recruited during high-velocity and high-power contractions. However, it is unknown whether BR influences alternative forms of exercise, such as resistance exercise. The purpose of this study is to assess whether BR supplementation influences neuromuscular performance (muscle power and speed), and repetitions-to-failure in healthy, recreationally active men. In a double-blind, randomized crossover design, 14 males will be recruited to complete two 4-day supplementation periods in which they consume …

Isolation Of Oral Bacterial Dna For 16s Rrna Sequencing To Determine Nitrate-Sensitive Oral Microbiota Following Acute Beetroot Juice Supplementation, Luka Sharabidze, Leah Stiemsma, Courtney Merrill, Chandler Riley, Maya Hammer, Ryan Kenney, Alyssa Riley, Katie Price, Adam Pennell, Rachel Tan

Seaver College Research And Scholarly Achievement Symposium

Dietary nitrate (NO3-) supplementation, provided as beetroot juice, improves cardiovascular, cognitive, and contractile function by augmenting nitric oxide (NO) biosynthesis; however, the specific taxa responsible, and whether NO3- ingestion can promote a favorable microbial composition to produce NO is yet to be established. To determine whether acute NO3- supplementation is associated with specific microbial taxa in females, 15 healthy adult females consumed an acute dose of NO3--depleted beetroot juice (PL) and NO3--rich beetroot juice (BR). Bacterial DNA from the buccal cells were isolated for subsequent 16s DNA sequencing for preserved regions in their 16s rRNA gene. Concentrations were assessed with …
