Measure	RENEW RENEW will occur on a recumbent ergometer that appears like a normal stepper ergometer. While resisting the foot pedal movement the participant experiences eccentric muscle contractions about the knee and hip while performing negative work. The progression of the 3 x/week (every other day), 12 week RENEW program will be determined as a function of the rating of perceived exertion (RPE) using a "target" workload on the monitor. RENEW will be increased very slowly over the first 3 weeks and, subsequently, to maintain an 11-13 perceived exertion. During the formal RENEW training regimen the participants become fully acclimated to the device (week 3-4) the total RENEW load will increase weekly with no increase in their RPE.	TRADITIONAL The TRAD group will perform their lower extremity resistance exercise for 15 minutes per session with isotonic weight machines and cuff weights as part of their multicomponent exercise fall reduction program (MCERFP). The progression of the 3 x/week, 12 week TRAD program will be determined as a relative function of their 1 repetition maximum (1RM) weight that can be lifted in a safe and successful manner. The 1RM will be measured before the 12 week training program and every 2 weeks thereafter. A "target" resistance workload (i.e., weight level) commensurate with 60-70% of the 1RM of the knee and hip extensors will be calculated bi-monthly and 3 sets of 15 repetitions of 3-4 different knee and hip exercises will be used over a 15 minute time period.

Magnetic resonance imaging (MRI) was used for determination of the cross-sectional area (CSA) (cm\^2) of lean muscle mass. Bilateral MRI scans of the thighs were obtained in a coronal plane and the midpoint of the thigh was determined and defined as halfway between the superior margin of the femoral head and the inferior margin of the femoral condyles. Axial imaging (5 mm thick slices at 1 cm intervals) of the legs was then performed over 1/2 the length of the femur, centered at the midpoint of the thigh. Five images from the middle 1/3 of each thigh were used to determine average CSA of lean tissue.

Leg extension power in watts (W) of each leg individually was measured on a Nottingham power rig. After three warm-up trials at 50%, 75%, and 100% effort, six test trials and the average of the three highest trials per leg were recorded.

Self-reported level of balance confidence was assessed with the Activities Specific Balance Confidence (ABC) Scale. This 16-item questionnaire asks participants to score their level of confidence in performing situation-specific activities such as "reaching at eye level," "reaching on tiptoes," "picking up slipper from floor," and "walking in crowded mall" "without losing . . . balance or becoming unsteady." Each item is scored from 0 to 100%, with 0% being no confidence and 100% being full confidence in the ability to perform the activity without losing balance. The total ABC Scale score is the average sum of the individual item scores.

The 6 min walk (6 MW) test, a measure of the distance (m) a subject walks in 6 min, was used to assess overall mobility. Self-selected gait-speed was measured over a 50-ft course. Individuals were instructed to walk at a comfortable pace starting at the word "go." They were asked to walk out 25-ft and back. Timing took place from the command "go" until the starting line was crossed on the way back. Participants were allowed to use any walking aid they used on a daily basis.
