“…Our findings show that ACT recovery has a better effect on repeated-sprint performance than PAS recovery or LFES. It is in accordance with several studies where ACT recovery better influenced performance or lactate removal than PAS recovery in different types of exercise [1][2][3][4][5][6][7][8][9][10][11].…”

Purpose. The study evaluates the effect of low-frequency electrical stimulation (LFES) of calf muscles on repeated-sprint performance and compares it with the frequently used active (ACT) and passive (PAS) recovery in amateur soccer players. Methods. A group of 11 amateur male soccer players completed 2 repeated-sprint ability (rSA) tests (7 × 34.2 m with 25 s of ACT recovery between sprints) separated by a 15-min recovery period. During recovery, 1 of the 3 recovery modalities (PAS, ACT, or LFES) was randomly selected. Results. Mean sprint time significantly increased between the first and the second rSA test after PAS (from 6.43 ± 0.21 s to 6.49 ± 0.23 s; p = 0.029) and LFES (from 6.45 ± 0.25 s to 6.54 ± 0.27 s; p = 0.025), whereas its values did not change significantly after ACT (from 6.42 ± 0.21 s to 6.45 ± 0.2 s; p = 0.093). However, small effect sizes indicate that the changes in mean sprint time after these 3 recovery modalities were not practically significant (PAS, d = 0.22; LFES, d = 0.29; ACT, d = 0.13). In addition, mean sprint time in the rSA test did not differ significantly between groups that underwent different recovery modalities. Conclusions. These findings indicate that practitioners can use any of these different recovery modalities, basing on their desire.

“…Intermittent exercise, which consists of repeated sets of exercise separated by periods of recovery, is suggested to produce comparable physiological adaptations to continuous exercise [13,19]. During intermittent exercise, lactate production also follows an intermittent pattern [20]. Therefore, to examine if intermittent exposure to lactate has the potential to induce mitochondrial adaptations, we cultured C2C12 myotubes for 2 h, but by changing the medium every 15 min (DM supplied with different concentrations of L-lactate; see Table 1).…”

Background: Exercise induces many physiological adaptations. Recently, it has been proposed that some of these adaptations are induced by exercise-mediated lactate production. In this study, we aimed to investigate in vitro the effect of lactate in cultured myotubes and whether antioxidants could inhibit the effect. Methods: Differentiated myotubes were cultured at different concentrations of L-lactate (0, 10, 30, 50 mM) in the absence or presence of an antioxidant, N-acetyl-L-cysteine (Nac). The temporal effect of lactate exposure in myotubes was also explored. Results: Two hours of exposure to 50 mM L-lactate and six hours of exposure to 30 or 50 mM L-lactate caused a significant increase in PGC1-alpha (peroxisome proliferator-activated receptor γ coactivator-1α) expression in the myotubes. This up-regulation was suppressed by 2 mM Nac. Intermittent and continuous lactate exposure caused similar PGC1-alpha up-regulation. These results suggest that the increase in PGC1-alpha expression is mediated by reactive oxygen species (ROS) production from lactate metabolism and that both continuous and intermittent exposure to L-lactate can cause the up-regulation.

“…Further confounding this issue is the active or passive nature of the HIIT/SIT recovery, as some studies do not sufficiently standardize the periods in between work bouts, allowing some participants complete rest while others perform active recovery. With regard to traditional Wingate‐based SIT, these periods account for >85% of the protocol duration, and differences between active or passive recovery may impact the return of

O 2 to resting values, as directly evidenced by recent work using a Wingate‐based SIT protocol . The degree to which the various protocols, including rest/recovery periods, are administered as planned or standardized across individuals is not often reported and, as such, warrants the question of whether the EPOC observed is due to methodological inconsistencies with measurement, or due to the protocol administration itself.…”

The post‐exercise recovery period is associated with an elevated metabolism known as excess post‐exercise oxygen consumption (EPOC). The relationship between exercise duration and EPOC magnitude is thought to be linear whereas the relationship between EPOC magnitude and exercise intensity is thought to be exponential. Accordingly, near‐maximal and supramaximal protocols such as high‐intensity interval training (HIIT) and sprint interval training (SIT) protocols have been hypothesized to produce greater EPOC magnitudes than submaximal moderate‐intensity continuous training (MICT). This review updates previous reviews by focusing on the impact of HIIT and SIT on EPOC. Research to date suggests small differences in EPOC post‐HIIT compared to MICT in the immediate (<1 hour) recovery period, but greater EPOC values post‐HIIT when examined over 24 hours. Conversely, differences in EPOC post‐SIT are more pronounced, as SIT tends to produce a larger EPOC vs MICT at all time points. We discuss potential mechanisms that may drive the EPOC response to interval training (eg, glycogen resynthesis, mitochondrial uncoupling, and protein turnover among others) and also consider the role of EPOC as one of the potential contributors to fat loss following HIIT/SIT interventions. Lastly, we highlight a number of methodological shortcomings related to the measurement of EPOC following HIIT and SIT.
