This study examines how each brain hemisphere contributes to motor control and coordination. Participants play virtual reality/computer games to look at how their arms move during different activities.

The earth’s climate is warming, and the number of heat waves has increased in recent years. At the same time, the number of adults over the age of 65 is growing. Humans sweat and increase blood flow to the skin to cool their body when they get hot. Older adults do not do this as well as young adults. This makes it harder to safely exercise in warm and/or humid conditions. It is important to learn about safe limits of heat and humidity for older adults to exercise. Also, nearly 40% of adults over age 50 take aspirin to lower their risk for heart disease. Our lab has shown that aspirin lowers the control of body heat.In this study, we will determine critical temperature and humidity environments above which normal body temperature cannot be maintained in young and older adults. We will also look at how aspirin may change critical temperature and humidity thresholds in older adults.

There will be 4 in person visits and sit, walk, or cycle at a low intensity in an environmental chamber.

The purpose of this research study is to see if we can use micro-doppler signal technology to determine if someone has had an ACL reconstruction in the past. We will do this by comparing a group of people who have had the surgery against a group who has never had this surgery to see if this technology can tell the difference.

If you join this study you would be asked to come to a one-hour appointment at the Lebanon Valley College campus in Annville, PA and perform a variety of activities that are part of daily life, such as walking, jumping, and standing from a seated position. We'll ask you to complete a questionnaire on any musculoskeletal pain you're experiencing and report your demographic information.

The purpose of this study is to determine what golf equipment and swing characteristics best predict playing ability in a population of golfers. Golfers will come to the laboratory and hit shots with various clubs while the movement of their body and the ball are tracked.

Participants will come to the Penn State Golf Teaching and Research Center and hit golf shots using their driver, 7 iron, and putter. A golf simulator will be used to track the ball trajectory. The movements of participant's body segments and the force they apply to the ground will be measured in three-dimensions as they swing. Participants will receive brief instruction from a Class-A PGA Professional upon completion.

The purpose of this study is to identify changes in salivary micro ribosomal nucleic acid (miRNA) expression that are predictive of symptom duration and severity following mild traumatic brain injury (mTBI) in children. The primary endpoints of this study are as follows:1)Characterization of brain-related miRNA in the saliva of 250 children with mTBI and 200 age- and gender-matched controls between the ages of five and twenty-three years.2)Identification of a set of salivary miRNAs that is predictive of duration and severity of mTBI symptoms.

Saliva collection and surveys at baseline, 7 days, and 30 Days

Description: This research study is to assess energetic status, reproductive health, and bone health in a population of young exercising men. Secondarily, this study will also explore how diet, fitness, cardiovascular function, eating behaviors, stress, cognitive function, and sleep related to energy and reproductive outcomes in exercising men. Eligible young men (age 18-35) are those who are generally healthy and either a) exercising or b) not exercising.

There will be essentially 5 study visits - The first visit will include informed consent to take part in the study & completion of questionnaires and measurement of anthropometrics. Visit 2 will include tests of your metabolism, a blood draw, a saliva collection, and assessment of diet and physical activity. Visit 3 will be a short visit for a saliva collection. Visit 4 will include tests of stress (a hair sample), body composition, bone health, aerobic and anaerobic fitness, cognitive testing, and reproductive function. Visit 5 will consist of a results meeting and return of wearable devices and logs.

This experimental study will investigate foot joint function during walking and running and/or hopping and performing heel raises. Participants will walk and run and/or complete heel raises with mass added to their body and will walk and run and/or hop with a plastic wedge secured to the underside of their toes.

The purpose of this trial is to test different levels of exercise needed to reduce liver fat in patients with NASH.

If you take part in this research, your major responsibilities will include: •Completing exercise sessions (if randomized to exercise group). A typical exercise session will include a 5 minutes warm-up with stretching, 15-45 minutes of brisk walking, jogging or recumbent bike and a 5-minute cool-down.

This study design is a survey that collects information about students' active level and supplement use, with an emphasis on creatine. The difference between contact and non-contact athletes will be examined, in addition to people who are considered inactive/low activity. This will help provide information of how physical activity related supplementation use affects cognition in different populations, with varying amounts of neurotrauma.

All participants will complete a digital survey that provides information about their dietary supplementation and physical activity habits. As part of the survey, participants will be allowed to indicate their interest and availability to come to a laboratory setting to complete a brief batter of neurocognitive tests.

This study will be a pilot study to evaluate the workability, safety and acceptability of Exercise and Liver FITness (EL-FIT), a mHealth exercise training program previously confirmed in patients with cirrhosis,(1) in patients with Nonalcoholic Steatohepatitis (NASH)

El-Fit NASH (Nonalcoholic Steatohepatitis) is a 9-week intervention trial for patients with NASH. Our goal is to evaluate the workability, safety and acceptability of Exercise and Liver FITness (EL-FIT), a mHealth exercise training program. The El-FIT application allows for participants to access to a library of guided workouts. All patients will be asked to complete a screening visit that includes a physical exam, height, and weight measurements & surveys. Participants will be asked to download the EL-Fit NASH application and use it for 8 weeks. In addition to using the application, participants will be asked to complete 3 check-in phone calls through-out the 8 weeks.

The aim of this study is to examine the effect of wearing CROCS with or without a heel-strap on walking mechanics.

There will be one in-person visit to take place at Penn State Altoona. During this visit, lasting approximately two hours, participants will undergo a simple consent process and they will provide information about their physical activity and fitness history. Body measurements, such as height, weight, and leg length will be recorded during the visit. Participants in the study will complete a five-minute treadmill warm-up at a self-selected walking speed while wearing a pair of CROCS, Inc. clog-style shoes (provided). After the warm-up participants will complete a series of 15 walking trials consisting of three randomized conditions (barefoot, no heel-strap, heel-strap) on a level and firm walking surface. During these trials, the participant will wear lightweight sensors on the lower-body to track walking patterns. Images and videos will be acquired during the visit, but all distinguishing features will be blurred or omitted upon archiving.

Average global temperatures and the number of heat waves have increased recently. Humans sweat and increase blood flow to the skin to cool their body when they get hot. Older adults (>65 yrs) do not do this as well as younger adults. This makes them at risk for heat-related illnesses. It is important to learn about cooling strategies that will lower body temperature for older adults in the heat. In this study, we will determine if placing your hands and forearms in cold water and/or supplementation with folic acid are effective cooling strategies for older adults resting in the heat.

There will be 4 in-person visits in a hot and humid environment, there will be folic acid supplementation and placebo for 6 weeks each
