NeuroSports

SCUBA diving requires a high level of cognitive functioning, however, many divers anecdotally report poor memory and attentional skills while underwater. Few studies have documented cognitive deficits resulting from an open-water dive. Here, 23 divers completed both shallow (8 m) and deep (28 m) dives over two days in the open-water. The order of the dives was counterbalanced across participants. While at depth, they completed the State-Trait Anxiety Inventory to assess anxiety levels, learned and were tested on a list of 36 words, and completed the trail making task (TMT) to assess executive functioning. They also gave saliva samples to …

Resistance Training Improves White Matter Structural Connectivity In Older Adults At-Risk For Cognitive Decline, Ryu Lien

Undergraduate Student Research Internships Conference

Diabetes is a global health concern that impacts 415 million people worldwide. Individuals who are at-risk for diabetes (characterized by high blood glucose and/or being overweight) have white matter atrophy, decreased cognitive function, and an increased risk of Alzheimer’s disease (AD). Recently, resistance training (RT) has been shown to lower white matter atrophy and white matter lesion volume. However, investigating changes in white matter tracts is complex, hence previous findings remain inconclusive. Diffusion tensor imaging (DTI) serves as a highly sensitive tool that enables visualization and characterization of white matter tracts and has the potential to combat this complexity. The …

Intensity-Specific Training Adaptations To Exercise In Females, Julianna P. Mereu

Undergraduate Student Research Internships Conference

Previous studies examining the effects of exercise training on metabolism have primarily used males as participants. It has been shown that as little as one hour of aerobic exercise in males leads to the alteration of several metabolic enzymes, including phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphate (G6Pase). Changes in glycogen content and differences in the usage of glycogen for fuel following exercise training have also been shown in male rats. However, it is unclear whether females demonstrate the same training related metabolic adaptations as males.

Therefore, the purpose of this project was to examine various metabolic responses to an acute exercise …

The Effect Of Type 1 Diabetes On The Metabolic Response To Exercise, Theres Tijo

Undergraduate Student Research Internships Conference

Type 1 Diabetes Mellitus (T1DM) is an autoimmune disorder that results in insufficient endogenous insulin production. Regular exercise has numerous health benefits for individuals with T1DM, however, most insulin-dependent diabetics avoid physical activity due to the fear of exercise-induced hypoglycemia (low blood glucose/BG).

The risk of hypoglycemia in this population may be partly due to lower liver glycogen stores which is a major source of blood glucose during exercise. However, the mechanism that leads to lower glycogen stores in T1DM is unknown.

The purpose of this study was to determine the effect of an acute bout of moderate-intensity aerobic exercise …
