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 study is to examine if nervous system and blood pressure responses to exercise will be less with heat exposure in patients with peripheral artery disease (PAD) and healthy controls.

AWS-PSU: Active Women's Study at Penn State University This research study is being conducted to evaluate the impact of exercise and reproductive function on bone strength. Eligible young women (age 18-30) are those that are generally healthy and either a) exercising and experiencing regular or irregular menstrual cycles, or b) not exercising and experiencing regular menstrual cycles.

Briefly, the purpose of this study is to use a self-management approach (combining education and exercise) to help older breast cancer survivors manage joint pain, a common side effect of aromatase inhibitors (AIs), a medication used to reduce hormones that might increase risk of recurrence and mortality following primary cancer treatment. We believe that reducing joint pain might help survivors take their medication longer and thus improve survival outcomes, compared to standard care.

This study aims to assess energy status in young sedentary and exercising women as it is related to menstrual status, bone health, psychological health, sleep variables, and cardiovascular function.

There will be three to four visits to the laboratory. Procedures include questionnaires, a blood draw, providing a hair sample, providing two saliva samples, cardiovascular measurements, and bone scans, as well as resting metabolic rate, cognitive, aerobic fitness, and countermovement jump testing. Participants will be asked to collect urine samples throughout one menstrual cycle, or 28 days for amenorrheic females. Exercise and physical activity will be recorded and monitored for seven days via logs and wearables. Food intake will be recorded for three days. Collegiate athletes will be tested twice; in-season and off-season.

To determine if the drug Amiloride will reduce exercise related muscle pain and improve exercise tolerance in healthy volunteers.

In each visit, you will be asked to perform foot exercise with, and without a blood pressure cuff inflated on your leg. You will also be asked to take pills prior to visit 2 and 3. One of these pills will be a drug called amiloride (10mg), which was traditionally used to lower blood pressure. The other pill will be a placebo (no active medication). During each visit, we will collect the following measurements:•We will collect a nerve recording from the leg not performing exercise, which will require a small needle-like electrode to be inserted behind your knee, just under the skin (a procedure called microneurography).•We will collect blood pressure from cuffs placed on your finger and upper arm.•We will collect blood lactate by sticking your finger with a small pin-prick (similar to taking a blood sugar measurement).•We will place to light-sensing device over the skin of your leg(s) to measure the oxygen level in your muscle.•We will hold a doppler ultrasound probe over your hip/leg region to measure blood flow.•We will use sticky-gel electrodes to measure heart rate and muscle activity.

This research is being conducted to determine how oxygen extraction within exercising muscles is altered in younger and older women when beta-1 receptors (receptors that contribute to the rise in heart rate with exercise) are temporarily blocked through a medication infused into an arm vein. The findings will help us understand how aging affects the regulation of oxygen supply to working muscles is regulated with normal aging.

There will be 3 in person visits.Visit 1) Subjects will undergo a physical and one blood draw in the Clinical Research Center and then perform two recumbent cycling exercise trials on a stationary bike.Visit 2) Subjects will undergo a DXA scan and then perform two recumbent cycling exercise trials.Visit 3) Subjects will have an IV catheter inserted into an arm vein. They will then perform two recumbent cycling exercise trials. During one trial the will receive esmolol via the IV catheter and during the other they will receive saline via the IV catheter (random order).

The primary objective of this study is to examine, via online focus groups, the perceptions that are held by potentially-eligible subjects in the PSH DPP program in regard to the importance of physical exercise, particularly within the context of diet, social connectivity, and stress reduction. These perspectives will then be used to help develop, test, and refine additional motivational text messages that can be used in a text messaging intervention. Participants will receive a $25.00 gift card.

This study will examine how the brain controls blood pressure responses during exercise, and will include 2 separate visits. In one visit, you will perform a series of handgrip exercises followed by inflation of a blood pressure cuff while we collect muscle nerve activity and blood pressure. In the other two sessions you will perform a similar task while laying in an MRI machine.

To determine if the sympathetic and blood pressure (BP) responses to exercise will be attenuated during and after heat exposure in patients with peripheral artery disease (PAD).
