The purpose of this study is to evaluate the effects of a home-based exercise program administered through Meals on wheels (MOW) on gait speed and frailty status and to assess the association between novel serum biomarkers (70 kilodalton heat shock proteins (HSP70),Macrophage Inflammatory Proteins(MIP1b), soluble IL-6 receptor alpha-chain (sIL-6R)) and established but non-specific frailty biomarkers (Interleukin 6 (IL-6), C-reactive protein (CRP), Tumor necrosis factor (TNF-α)) in frail and prefrail homebound older adults before and after the exercise intervention.

| Meals plus exercise | Behavioral | Participants will receive 12 weeks of a MOW delivery service that will include 2 meals per day during the weekdays with 4 shelf-stable meals at the end of the week. The MOW driver will visit the participants in-person to ask a series of 5 questions about change in health status, joint/muscle injuries, new pain, falls, and poor appetite twice a week. Participants will also will receive an exercise kit from the MOW driver with their first meal delivery which will contain 2 tennis balls, 2 1-pound hand weights, and one towel. Every week, the driver will give the participants a handout containing 3 exercises from the NIA Go4Life Workout-to-Go book that are designed to help with strength/endurance, balance, and flexibility20. The participants will be asked to do the 3 exercises every day, if possible, on their own. Every 4 weeks during the 12-week study period and at 6 months follow up patients will have blood drawn for frailty and inflammatory biomarkers. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in gait speed | this is the time one takes to walk a specified distance on level surfaces over a short distance and is measured in meters/second | 4 weeks,8 weeks,12 weeks from baseline |
| Change in total FFP score as assessed by the Fried Frailty Phenotype (FFP) screening test | Score from 0(not frail),1-2(pre frail) and 3-5(frail) | 4 weeks,8 weeks,12 weeks from baseline |
| Change in measure of HSP70 (ng/mL) expression | 4 weeks,8 weeks,12 weeks from baseline | |
| Change in Measure of MIP-1β (pg/mL) expression | 4 weeks,8 weeks,12 weeks from baseline | |
| Change in Measure of sIL-6R (pg/mL) expression | 4 weeks,8 weeks,12 weeks from baseline |
| Measure | Description | Time Frame |
|---|---|---|
| Change in overall frailty status as assessed by the Fried Frailty Phenotype (FFP) screening test | The FFP defines frailty as having 3 or more characteristics of unintentional weight loss, fatigue, decreased physical activity, weakness, and slowness.Those who have 1 or 2 characteristics are considered pre frail, while those who have no characteristics are robust. | 4 weeks,8 weeks,12 weeks from baseline |

| Meals only | Behavioral | Participants will receive 12 weeks of a MOW delivery service that will include 2 meals per day during the weekdays with 4 shelf-stable meals at the end of the week. The MOW driver will visit the participants in-person to ask a series of 5 questions about change in health status, joint/muscle injuries, new pain, falls, and poor appetite twice a week. they will be asked to continue their usual level of activity.Every 4 weeks during the 12-week study period and at 6 months follow up patients will have blood drawn for frailty and inflammatory biomarkers. |

| Change in grip strength | Grip strength is a measure of muscular strength or the maximum force/tension generated by one's forearm muscles .This is measured by using a dynamometer which will be squeezed by the participant 3 times in each hand.The force is measured in kilograms. | 4 weeks,8 weeks,12 weeks from baseline |
