Rationale: 
Cardiovascular diseases are the leading cause of morbidity and mortality in individuals with obesity, promoting the development of cardiac rehabilitation programs where structured exercise is a key component. However, estimating optimal training intensity remains challenging, especially in early stages when cardiopulmonary exercise testing is not always available.
Objectives
To develop an intensity estimation strategy for strength and endurance exercises based on accessible and reproducible morphofunctional variables and functional tests.
Methods: Retrospective study in patients with cardiovascular disease. Assessment included vectorial bioimpedance, nutritional ultrasound (muscle and adipose tissue), dynamometry (handgrip, biceps, quadriceps), 20-repetition maximum (20RM), 6-minute walk test (6MWT), and ergometry. Regression models were performed using Jamovi®.
Results: A total of 156 patients were included (57.6 ± 7.9 years; BMI 31.1 ± 4.0 kg/m²). Mean values: phase angle 5.72 ± 0.97°, fat mass 32.3 ± 7.6%, rectus femoris area 5.12 ± 1.36 cm². Dynamometry: handgrip 34.6 ± 10.1 kg, biceps 43.1 ± 13.0 kg, quadriceps 46.1 ± 12.7 kg. Ergometry showed 9.49 ± 2.53 METs and 6MWT distance was 273 ± 75.7 m.
Handgrip strength correlated with 20RM in biceps (ρ = 0.440) and quadriceps (ρ = 0.402), p < 0.001. Predictive models:
• 20RM Biceps = 2.68 + 0.050 × HGSmax (R² = 0.246)
• 20RM Quadriceps = 2.87 + 0.077 × HGSmax (R² = 0.167)
METs correlated with walking distance (r = 0.451), speed (r = 0.510), and Borg scale (r = −0.274). Predictive formula:
METs = 18.26 − 0.092 × Age − 1.17 × Sex (F) + 0.011 × 6MWD − 0.541 × Borg (R² = 0.332).
Conclusion: Handgrip dynamometry is a useful predictor for estimating resistance loads, suggesting ~10% adjustment for upper limbs and ~20% for lower limbs. The 6MWT may be a practical alternative to ergometry for initial aerobic prescription.
