Chiropractic , exercise and movement ! There is a saying of Don’t let the old man in… Preparing yourself to live a better quality of life later starts early! But its never too late to improve!
Role of sit-to-stand muscle power in healthy ageing:
Assessing validity
Clinical relevance
Decline and interventions in older adults
With and without chronic conditions.
📌 What the study is about
⇝ Focus: Sit-to-stand (STS) muscle power – basically, how much power (strength × speed) a person generates when standing up from a chair.
⇝ Context: STS is a fundamental daily-life movement. It reflects lower-limb strength, neuromuscular function, and overall mobility.
⇝ Population studied: Older adults, both healthy and those with chronic conditions.
Main Aims
1. Validity – Is STS muscle power a reliable and valid measure of physical performance in ageing populations?
2. Clinical relevance – Does it correlate with important health outcomes (mobility, independence, fall risk, mortality)?
3. Age-related decline – How does STS muscle power decrease with ageing compared to other measures (strength, gait speed)?
4. Interventions – What types of exercise or training can improve STS power in older adults?
Key Findings (from the award summary & related works by Dr. Baltasar-Fernandez)

Key Findings (from the award summary & related works by Dr. Baltasar-Fernandez)
⇝ STS power declines significantly with age, often faster than muscle mass loss.
⇝ It predicts mobility limitations, falls, and frailty better than simple strength tests.
⇝ Both healthy older adults and those with chronic diseases (e.g., cardiovascular or metabolic conditions) show reduced STS power.
⇝ Exercise interventions (resistance training, power training, sit-to-stand practice) can improve STS muscle power, thereby enhancing independence and quality of life.
Why it matters (Clinical Application)
◉ STS muscle power could be a simple clinical test (using a chair and stopwatch or force plate) to screen older adults at risk of disability.
◉ It is more functional and task-specific than isolated strength measures (like the leg press).
◉ Tracking STS muscle power helps guide rehabilitation and exercise prescriptions for ageing populations
