“…The lower cardiometabolic responses during the eccentric protocol are in line with the findings of previous studies, where mean values for HR and blood lactate concentrations were even lower than that reported for concentric continuous low-intensity exercise [8,18]. Moreover, the present concentric protocol also exhibited very low HR and peak blood lactate values when compared to previous studies with concentric modified SIT protocols, probably because of the lower number of sprints (8 vs. 16 sprint bouts) and the longer recovery time (55 vs. 24 s) [28,36]. However, in the current study, subjects were not able to achieve greater peak power values in the eccentric than in the concentric sprint bouts.…”

Background: To the authors’ knowledge, there have been no studies comparing the acute responses to “all out” efforts in concentric (isoinertial) vs. eccentric (isovelocity) cycling. Methods: After two familiarization sessions, 12 physically active men underwent the experimental protocols consisting of a 2-min warm-up and 8 maximal efforts of 5 s, separated by 55 s of active recovery at 80 rpm, in concentric vs. eccentric cycling. Comparisons between protocols were conducted during, immediately after, and 24-h post-sessions. Results: Mechanical (Work: 82,824 ± 6350 vs. 60,602 ± 8904 J) and cardiometabolic responses (mean HR: 68.8 ± 6.6 vs. 51.3 ± 5.7% HRmax, lactate: 4.9 ± 2.1 vs. 1.8 ± 0.6 mmol/L) were larger in concentric cycling (p < 0.001). The perceptual responses to both protocols were similarly low. Immediately after concentric cycling, vertical jump was potentiated (p = 0.028). Muscle soreness (VAS; p = 0.016) and thigh circumference (p = 0.045) were slightly increased only 24-h after eccentric cycling. Serum concentrations of CK, BAG3, and MMP-13 did not change significantly post-exercise. Conclusions: These results suggest the appropriateness of the eccentric cycling protocol used as a time-efficient (i.e., ~60 kJ in 10 min) and safe (i.e., without exercise-induced muscle damage) alternative to be used with different populations in future longitudinal interventions.

“…The meta-analysis included a total of 438 participants, of whom 239 performed supervised sSIT, 107 participants performed no exercise or no additional sSIT, 49 performed HIIT as control condition, 45 performed other SIT modality as control condition, and 13 performed CT as control condition. Of the included studies, cycling was the most common mode of exercise (8 studies), 13,19,[33][34][35][36][37][38] followed by running (6 studies). 11,[39][40][41][42][43] Additionally, boxing exercise, 44 canoe paddling, 45 functional fitness exercises, 46 handcycling, 47 and squatting + cycling 19 were also assessed by one study each.…”

The effects of short sprint interval training (sSIT) with efforts of ≤10 s on maximal oxygen consumption (V̇O2max), aerobic and anaerobic performances remain unknown. To verify the effectiveness of sSIT in physically active adults and athletes, a systematic literature search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA). The databases PubMed/MEDLINE, ISI Web of Science, and SPORTDiscus were systematically searched on May 9, 2020, and updated on September 14, 2021. Inclusion criteria were based on PICO and included healthy athletes and active adults of any sex (≤40 years), performing supervised sSIT (≤10 s of “all‐out” and non‐“all‐out” efforts) of at least 2 weeks, with a minimum of 6 sessions. As a comparator, a non‐sSIT control group, another high‐intensity interval training (HIIT) group, or a continuous training (CT) group were required. A total of 18 studies were deemed eligible. The estimated SMDs based on the random‐effects model were −0.56 (95% CI: −0.79, −0.33, p < 0.001) for V̇O2max, −0.43 (95% CI: −0.67, −0.20, p < 0.001) for aerobic performance, and −0.44 (95% CI: −0.70, −0.18, p < 0.001) for anaerobic performance after sSIT vs. no exercise/usual training. However, there were no significant differences (p > 0.05) for all outcomes when comparing sSIT vs. HIIT/CT. Our findings indicate a very high effectiveness of sSIT protocols in different exercise modes (e.g., cycling, running, paddling, and punching) to improve V̇O2max, aerobic, and anaerobic performances in physically active young healthy adults and athletes.

“…Since the level of self-efficacy, motivation, and enjoyment are predictors of physical activity participation (PA) [ 5 ], it has been suggested that reducing bout duration elicits more positive affective responses [ 4 ]. This is a great advantage of modified SIT which has been shown to significantly improve the cardiometabolic profile in healthy and unhealthy adults [ 2 , 6 , 7 , 8 ]. In addition, modified SIT requires lower total volume [ 6 , 8 ] which could mitigate the lack of time indicated as the main barrier to engaging in regular PA [ 5 ].…”

The aim of this study was to compare the acute responses to three time-matched exercise regimens. Ten trained adults (age, maximum oxygen consumption (VO2max), and body mass index (BMI) = 25.9 ± 5.6 yr, 50.9 ± 5.4 mL·kg−1·min−1, and 22.1 ± 1.8 kg·m−2) completed sprint interval training (SIT) requiring 14 × 5 s efforts with 35 s of recovery, high-intensity interval training (HIIT) consisting of 18 × 15 s efforts at ~90% of peak heart rate (HRpeak) with 15 s of recovery, and vigorous continuous training (CT) consisting of 8.75 min at ~85 %HRpeak, in randomized order. Heart rate, blood lactate concentration, rating of perceived exertion, affective valence, and enjoyment were monitored. Moreover, indices of neuromuscular function, autonomic balance, diet, mental stress, incidental physical activity (PA), and sleep were measured 24 h after each session to analyze the magnitude of recovery. Both HIIT and CT exhibited a greater %HRpeak and time ≥ 90 %HRpeak than SIT (p < 0.05). Blood lactate and rating of perceived exertion were higher in response to SIT and HIIT vs. CT (p < 0.05); however, there were no differences in enjoyment (p > 0.05). No differences were exhibited in any variable assessed along 24 h post-exercise between conditions (p > 0.05). These data suggest that HIIT and CT accumulate the longest duration at near maximal intensities, which is considered a key factor to enhance VO2max.
