A pilot, single-arm investigation used coaching, nutrition education, and a per-meal protein prescription to assess impact on protein intake, muscle strength and function in older adults.
Objective: To evaluate the effects of nutrition education, diet coaching, and a protein prescription (PP) on protein intake, and associations with muscle strength and function. Design: Prospective pretest posttest single-arm study. Setting: Urban area, East coast of South Florida. Participants: Older adults. Intervention: 10-week telephone-based diet coaching, nutrition education and a per-meal PP. Measurements: Protein and energy intakes, weight, grip strength (GS), and 5-chair-rise (5CR), timed up and go (TUG), 3-meter walk (3mW) tests at baseline and 10 weeks.

Change in Protein intake
Protein intake (g/kg/body weight) per day
Time frame: Change from baseline to 10 weeks
Change in Grip strength
Grip strength measured using dynamometer
Time frame: Change from baseline to 10 weeks
Change in Timed Up and Go Test
The timed up and go test measures the time (in seconds) that it takes to stand up from a seated position in a chair, walk 3 meters away from the chair at a comfortable pace to a line on the floor, turn around, walk back, and sit back down in the chair.
Time frame: Change from baseline to 10 weeks
Change in 3 meter walk
The 3-meter walk test measures the time (in seconds) that it takes to stand up from a seated position in a chair and walk 3 meters away from the chair at a comfortable pace to a line on the floor
Time frame: Change from baseline to 10 weeks
Change in 5-Chair Rise Stand Test
The 5 chair rise stand test requires participants to stand up 5 times without hand assistance from a straight back chair without an armrest. The time required to complete the 5 chair rises is recorded.
Time frame: Change from baseline to 10 weeks
Change in Short Performance Physical Battery Score
The Short Physical Performance Battery (SPPB) consists of timed measures of balance, 3-meter walk, and 5-chair rises. The balance portion requires participants to stand with feet next to each other, the toes of one foot next to the heel of the other foot, and heel to toe for a 10 second duration. Scores are assigned based on the number of seconds the participant can stand in the position for balance. Scores for the chair rise and 3 meter walk are based on the time taken to complete the task. The scores are totaled to arrive at the Short Performance Physical Battery Score
