Post Infarction Exercise Effects on Myocardial Function Assessed by 2D Strain Ultrasound

"This program takes place at the Cardiovascular Rehabilitation Department at the Nîmes University Hospital and includes a combination of various physical activities: treadmill, exercise bike, rower, aerobics, gymnastics, serious games, swimming. The program begins approximately within 3 months after myocardial infarction and consists of 20 consecutive days of training. The main physical activity is aerobic interval training (AIT).~30-minute AIT sessions will occur 5x per week for 4 weeks.~1 AIT session includes a warm up for 8 minutes to reach a heart rate during exercise corresponding to 20 to 30% of maximum aerobic power determined during the initial effort test. Then interval training occurs with 4x2 min of high intensity effort (heart rate during exercise corresponding to 80% of maximum aerobic power) alternating with 2 min of active recovery at 20-30% of maximum aerobic power. Then recovery for 8 minutes."
