Trial name or title	Effects of a program of high intensity exercise by intervals on the risk of falls for the physical condition and the state of health in people over 60 years
Methods	RCT
Participants	Target sample size: 45 Inclusion criteria: Men and women, aged 60 ‐ 80 years Exclusion criteria: diseases that may alter balance and functional activity (such as auditory or vestibular alterations), central or peripheral neurological disorders, other rheumatological diseases, or serious psychiatric or somatic diseases
Interventions	1 and 2: training twice a week for 12 weeks 1. High‐intensity interval training (HIIT) group: Squat training with the Suspension Training System (TRX). The session will be divided into 4 x 4‐minute intervals at an intensity of 90 ‐ 95% of the maximum heart rate, followed by 3‐minute active rest intervals of 50 ‐ 70%. Followed by 10 minutes of exercises of joint range 2. Moderate‐intensity continuous training (MICT) group: Squat training with the Suspension Training System (TRX) with an intensity close to 70% of their maximum heart rate maintained for 40 minutes. The session will conclude with a return to calm of 10 minutes of joint width and stretching. 3. No intervention group
Outcomes	1. Gait and balance parameters 2. Mobility 3. Balance 4. Strength 5. Balance confidence 6. Falls self‐efficacy 7. Body composition 8. Health‐related quality of life
