The general hypothesis is that elderly have diminished nutritive flow to skeletal muscle and impaired capacity for building muscle. In aging populations, this decreased ability to build muscle may represent a tipping point in the progression towards chronic physical frailty and disability. The goal is to examine whether novel pharmacologic therapies can improve nutritive blood flow to the muscles and muscle building in the elderly.
The purpose of this study is 1) to determine if losartan administration will enhance blood flow and 2) to determine if N-acetylcysteine (NAC) will enhance blood flow.
The investigators will study community dwelling, healthy older men and women (60-85 years). Subjects will be randomized to one of three groups:
Experimental Group 1: Placebo losartan and placebo N-acetylcysteine (NAC). Experimental Group 2: losartan (25mg/dose) and placebo N-acetylcysteine (NAC). Experimental Group 3: N-acetylcysteine (NAC) (50 mg/kg/dose) and placebo
Subjects will admit to the clinic on day 1 of the study. Baseline testing consisting of leg blood flow (LBF), contrast enhanced ultrasound, handgrip testing and fatigue questionnaires. After testing is completed the subjects will recieve their first dose of NAC/ losartan/ placebo with dinner. Subjects will be fasted after 10 pm. On day 2, leg blood flow (LBF) will be measured approximately 12 hours post dose 1. Subjects will receive their second dose of NAC/ losartan/ placebo. Leg blood flow will be measured 1 hour and 2 hours post dose 2 of study interventions. The subjects will eat a meal and receive their third dose of the study intervention. Leg blood flow will be repeated at 1 hour and 2 hours post dose 3. Appoximately 30 minutes after dose 3 of the study intervention, handgrip testing will be performed and fatigue questionnaires completed.

| Leg Blood Flow as Measured by Doppler Ultrasound | Femoral Doppler Blood Flow was evaluated via Doppler ultrasound. For the two-dimensional (2-D) and Doppler ultrasound measurements, an ultrasound system (HDI-5000; Philips Medical Systems, Bothell, WA) with a linear array transducer (L7-4) was used with a transmit frequency of 12MHz. 2-D imaging of the common femoral artery will be performed in the long axis. Images will be triggered to the R wave of the cardiac cycle, and the femoral artery diameter will be measured using online video calipers. A pulsed-wave Doppler sample blood volume will be placed at the same location in the center of the artery, and the mean blood velocity will be measured using online angle correction and analysis software. Femoral artery mean blood flow will be calculated from 2-D and Doppler ultrasound data using the equation: Q = vπ ∙ (d/2)2, where Q is femoral blood flow, v is mean femoral artery blood flow velocity, and d is femoral artery diameter. | Baseline |

| Primary | Leg Blood Flow as Measured by Doppler Ultrasound | Femoral Doppler Blood Flow was evaluated via Doppler ultrasound. For the two-dimensional (2-D) and Doppler ultrasound measurements, an ultrasound system (HDI-5000; Philips Medical Systems, Bothell, WA) with a linear array transducer (L7-4) was used with a transmit frequency of 12MHz. 2-D imaging of the common femoral artery will be performed in the long axis. Images will be triggered to the R wave of the cardiac cycle, and the femoral artery diameter will be measured using online video calipers. A pulsed-wave Doppler sample blood volume will be placed at the same location in the center of the artery, and the mean blood velocity will be measured using online angle correction and analysis software. Femoral artery mean blood flow will be calculated from 2-D and Doppler ultrasound data using the equation: Q = vπ ∙ (d/2)2, where Q is femoral blood flow, v is mean femoral artery blood flow velocity, and d is femoral artery diameter. | Posted | Mean | Standard Deviation | ml/minute | 12 hours post dose one of the intervention |

| Secondary | Personal Perceptual Fatigue Measured by Multidimensional Fatigue Symptom Inventory - Subscale General Fatigue at Baseline | Multidimensional Fatigue Symptom Inventory Short Form (MFSI-SF) from the Moffitt Cancer Center, University of South Florida The MFSI-SF is a 30 question assessment designed to assess the principal manifestations of fatigue. There 5 subscales used to calculate a total score. The subscales are: General Fatigue, Physical Fatigue, Emotional Fatigue, Mental Fatigue, and Vigor (an estimate of the patient's energy level). The total score is calculated with the equation: (general + physical + emotional + mental) - vigor = total score. The range of the general fatigue scale is 24 to 0, with the higher number meaning more fatigue. The range of the total score is -24 to 96, with the higher the number meaning more fatigue. | Posted | Mean | Standard Deviation | units on a scale | Baseline |

Handgrip testing was performed at baseline (before any intervention) and post dose three of the intervention, average of 17 hours post dose one intervention. | Data for 1 subject was not collected. | Posted | Mean | Standard Deviation | units on a scale | Post dose three of the intervention, average of 17 hours post dose one intervention - Directly after handgrip fatigue test |

| Secondary | Perceptual Fatigue of Whole Body as Measured by Visual Analog Scale Before Handgrip Fatigue Test at Baseline. | The Visual Analog Scale for Fatigue is an 11cm long line. The subject is asked to mark their level of fatigue (0cm being no fatigue and 11cm being extreme fatigue). This test was performed before and after the handgrip fatigue test, where the non-dominant hand hold a continuous contraction at 20% of the subjects maximal voluntary contraction for 5 minutes. Handgrip testing was performed at baseline (before any intervention) and post dose three of the intervention, average of 17 hours post dose one intervention. | Posted | Mean | Standard Deviation | units on a scale | baseline - before handgrip fatigue test |
