Training characteristics.

Exercise	Instrument	Observations
1. Unilateral chest press	e-Lastic®	OMNI-RES 5 to 6 during 12 initial weeks. The exercise was performed with the contralateral arm to the fistula. A conservative measure intended to preserve arteriovenous fistula. The e-Lastic load record was the peak (maximum) load achieved in each movement to count the repetitions.
2. Squat	Bodyweight	OMNI-RES 7 to 8 during 12 last weeks From 4 to 15 reps—weekly increasing the number of reps At the beginning of the protocol, we encourage patients to perform few squats (4reps) but weekly increasing the number of reps.
3. Unilateral row	e-Lastic®	The exercise was performed with the contralateral arm to the fistula. A conservative measure intended to preserve arteriovenous fistula. The e-Lastic load record was the peak (maximum) load achieved in each movement to count the repetitions.
4. Bilateral knee extension	Weighted cuffs	Seated position Wrapped at the ankle.
5. Unilateral shoulder press	Dumbbells	Exercise performed with the arm contralateral to fistula. A conservative measure intended to preserve arteriovenous fistula.
6. Hip thrust	Weighted cuffs	Positioned at the hips.
7. Unilateral knee flexion	Weighted cuffs	Stand position Wrapped at the ankle.
8. Biceps curl	Dumbbells	The exercise was performed with the contralateral arm to the fistula. A conservative measure intended to preserve arteriovenous fistula.
9. Unilateral hip adduction	e-Lastic®	The e-Lastic load record was the peak (maximum) load achieved in each movement to count the repetitions.
10. Unilateral elbow extension	Dumbbells	The exercise was performed with the contralateral arm to the fistula. A conservative measure intended to preserve arteriovenous fistula.
11. Unilateral hip abduction	e-Lastic®	The e-Lastic load record was the peak (maximum) load achieved in each movement to count the repetitions.
12. Seated calf raise	Weighted cuffs	Wrapped across the quadriceps
