To investigate the effect of an fitness advice and resistance band exercise intervention on balance, muscle function, and power in an older people population who have low muscle power.

Enrollment
104
Participants will be given a resistance band and at set of exercises that target the lower extremities and asked to perform these as three sets of 15 repetitions, 2 times a week.
Participants will be undertake a series of functional fitness tests and have their performance evaluated against normative values for their age and sex. Following this advice will be given with the aim of empowering change in physical activity participation.

RECRUITINGPostural sway
Using a force plate recording at 100Hz for 30 seconds, 5 eyes open and eyes closed trials will be recorded at baseline and after 12 weeks of resistance band exercises. Using the Centre of Pressure measurements provided. Linear (e.g. total sway path length and sway path in the medio-lateral and anterior-posterior directions, measured in meters) and non-linear (fractal dimension, unitless measurement units) postural control measurements will be calculated.
Time frame: after 12 weeks
Five times sit to stand time
Sitting on a chair, participants stand to full leg extension, and then return to a seated position 5 times, and the time taken recorded in seconds.
Time frame: After 12 weeks
Single leg stand time
This is the length of time, in seconds, an individual can stand on a single leg for as long as possible (up to a maximum of 90 seconds)
Time frame: After 12 weeks
Timed up and go
This is the time, in seconds, it takes for an individual to stand from a seated position, without using their hands, walk around a cone which is 3 meters away, before returning to the seated position.
Time frame: After 12 weeks
Muscle power
Using a Biodex dynamometer, 5 practice and 5 trial concentric muscle efforts will be performed with the peak torque (newton meters), time to peak torque (seconds) and peak torque (newton meters) at 0.18 seconds will be recorded.
Time frame: After 12 weeks
Grip strength
using and hand strength dynamometer, grip strength will be measured as the maximum value of 2 maximal efforts using their dominant hand. This is measured in kilograms.

Time frame: After 12 weeks
Fear of falling
Falls efficacy scale - international questionnaire (https://sites.manchester.ac.uk/fes-i). The total score of questions will be used in the analysis.
Time frame: After 12 weeks
Self-efficacy for exercise
Self-efficacy for exercise questionnaire (SEE) (https://www.sralab.org/sites/default/files/2017-06/Self-efficacy%20for%20exercise\_Website\_PDF.pdf). The total score of 9 questions will be used in the analysis. The Scale: Each question is rated from 0 (Not Confident) to 10 (Very Confident). Scoring: Add the numbers for all 9 responses together. Range: Total scores range from 0 to 90. Interpretation: Higher totals indicate a greater level of self-efficacy (stronger belief in your ability to maintain an exercise routine).
Time frame: After 12 weeks
Perceived change in body, balance and power
Using a 15 point Likert Global Rating of Change scale (GRC) to measure perceived change. +7 to +1: Ranging from "A very great deal better" (+7) to "A little better" (+1) 0: No change -1 to -7: Ranging from "A little worse" (-1) to "A very great deal worse" (-7) This scale will be completed for the measurement of perceived change in body, balance and power separately (i.e. there will be a separate scores given for each domain).
Time frame: After 12 weeks
Quality of life
The Older People Quality of Life questionnaire (OPQOL) will be completed (https://ilcuk.org.uk/wp-content/uploads/2019/03/OPQOL-full-questionnaire.pdf). Each subsection of the OPQOL will be analysed separately. This is scored on a 5 point scale 1 = very good to 5 = very bad. The scores are reversed so that a higher value suggests better quality of life. In each subsection values are summed. Subsections Live overall = min score is 4 and max score is 20 Health = min score is 4 and max score is 20 Social relationships = min score is 5 and max score is 25 Independence, control over life, freedom = min score is 4 and max score is 20 Home and neighbourhood = min score is 4 and max score is 20 Financial circumstances = min score is 4 and max score is 20 Leisure and activities = min score is 6 and max score is 30
Time frame: 12 weeks
