Ασκήσεις για γηριατρική ευθραυστότητα — δύναμη με ταχύτητα, όχι αργή

The Fried 2001 frailty phenotype defined a distinct geriatric syndrome characterised by unintentional weight loss, exhaustion, slow walking speed, low grip strength, and low physical activity. Three or more = frail; one or two = pre-frail. The 2010 LIFE (Lifestyle Interventions and Independence for Elders) trial showed that progressive resistance + aerobic + balance training reduces the rate of progression from pre-frail to frail and improves functional outcomes. The breakthrough finding: POWER training (fast eccentric and concentric movement under load) outperforms slow traditional strength training for functional outcomes that matter — getting up from a chair faster, recovering from a stumble, climbing stairs without falling. Slow heavy strength still has value, but at a given workload, the speed component drives functional gain. The critical safety caveat: AVOID high-velocity work on unstable surfaces in the pre-frail/frail population. Build on stable ground. Sarcopenia (age-related muscle loss) drives much of frailty — protein 1.2-1.5 g/kg is standard for older adults, with vegan elderly needing 1.5-1.8 g/kg due to lower bioavailability + lower leucine content of plant proteins.

Volya's catalogue carries the frailty-appropriate foundation: sit-to-stand for functional strength + the eccentric leg work that addresses chair transfers (the most fall-risky daily activity), single-leg-stance and tandem-stance and heel-to-toe-walk for the balance progression that addresses fall risk, wall-push-up for upper-body strength without floor work that's hard for the elderly to get back up from, supported-glute-bridge for joint-friendly glute work, standing-march for cardio with built-in balance challenge, scapular-retraction for posture against thoracic kyphosis, diaphragmatic-breathing for autonomic regulation. The AI coach also knows the nutrition side — protein 1.2-1.5 g/kg (1.5-1.8 vegan) distributed evenly across meals to hit the 2.5-3 g leucine per-meal anabolic threshold (vegan needs soy isolate, seitan, hemp + pea blends), vitamin D 800-2000 IU (deficiency near-universal in homebound elderly), calcium 1000-1200 mg, B12 absorption drops with age (test + supplement omnivores too; vegan mandatory), omega-3 algae for vegans, hydration with reminders (thirst response blunts with age), limit ultra-processed, drug-nutrient interactions for polypharmacy (PPIs/metformin/thiazides/warfarin). This is NEVER a replacement for geriatric medical care — frailty interventions work best with team coordination.
