Abstract
Background
Exercise-induced adaptations of the human atria remain understudied, particularly early in the training process. We examined the effects of short-term high-intensity interval training (HIT) and continuous moderate-intensity training (CMT) on left atrial (LA) systolic and diastolic function, relative to left ventricular (LV) function in young, healthy men, by speckle tracking echocardiography (STE).
Methods
Fourteen untrained men (mean age = 25 ± 4 years) were randomized to HIT or CMT, and assessed before and after six training sessions over a 12-day period. HIT included 8-12 intervals of cycling for 60 s at 95–100 % of maximal aerobic power (VO2MAX), interspersed by 75 s of cycling at 10 % VO2MAX. CMT consisted of 90–120 min of cycling at 65 % VO2MAX.
Results
VO2MAX increased following HIT and CMT by 11.5 and 5.5 %, respectively (p < 0.05). Calculated plasma volume expanded 11 % following HIT and 10 % following CMT (p < 0.005). Resting LV volumes and ejection fraction were unaltered following training. Peak atrial longitudinal strain increased following HIT (41.8 ± 5.2 %–47.1 ± 3.7 %, p < 0.01) and CMT (38.5 ± 4.6 %–41.7 ± 6.0 %, p < 0.01). Atrial systolic strain rate increased following HIT (1.6 ± 0.2 %/s–2.0 ± 0.3 %/s, p < 0.01) and CMT (1.6 ± 0.2 %/s–1.9 ± 0.2 %/s, p < 0.01).
Conclusions
LA function assessed by STE improves rapidly during short-term intensive exercise training.
