Furthermore, it has already been described presence of autonomic dysfunction. As a result of the rapid progression and severity of the disease, people with ALS experience loss of functionality and independence. In conclusion, eccentric exercise with or without BFR with different load was not enough to cause autonomic and cardiovascular imbalance in post-exercise recovery.Īmyotrophic lateral sclerosis (ALS) is a neurodegenerative disease. Increase in vagal indices was observed in the final moments of recovery for the LLEE-BFR and HLEE-BFR. Differences between moments were observed only for the respiratory rate variable in the LLEE-BFR and HLEE-BFR in the first minute of recovery (21.13±5.00 and 21.25±4.55 irpm, respectively) in relation to the baseline (17.07☒.81 and 18.00☒.92 irpm, respectively). moments) for any of the cardiovascular variables and autonomic indices analyzed, and there were no differences between groups. Variance analysis for a repeated measures model in the two-factor scheme was used with p<0.05. Cardiovascular repercussions and heart rate variability were analyzed at baseline and for 60 min post exercise. The participants underwent a single session of eccentric exercise for the quadriceps muscle in the dynamometer. Sixty men were randomized in four groups: low and high load eccentric exercise (LLEE and HLEE) LLEE and HLEE with BFR (LLEE-BFR and HLEE-BFR). The objective was compare acute autonomic and cardiovascular responses following different loads of eccentric exercise with and without BFR. Resistance training with blood flow restriction (BFR) has emerged as an method to gain strength and hypertrophy, however, the autonomic and cardiovascular repercussions of BFR and whether there is a dose-response relationship considering the load of the exercise when applied by means of eccentric contractions are not yet known.
