“…Due to the intense nature of the protocol, it is often hypothesized that HIIT/SIT elevates EPOC to a greater extent than MICT, and over the course of the day may result in an energy deficit not accounted for in the estimated caloric expenditure associated with the session itself . However, as discussed in the present review, greater EPOC values have been consistently documented following SIT only, and equivocally following HIIT, compared to MICT, with the resultant increases in energy expenditure negligible in the immediate hour post‐exercise. Furthermore, these increases in energy expenditure are similar to, and sometimes greater than that which is induced by MICT at 24 hours.…”

“…19,[24][25][26][27] Furthermore, some studies suggest that HIIT results in elevated V O 2 compared to MICT and baseline at ~21 hours post-exercise, 28,31 while others have reported a return to baseline V O 2 levels within 1 hour post-exercise. 18,19,24,32 In contrast, the differences in V O 2 post-SIT compared to MICT are more pronounced, and SIT tends to produce greater EPOC magnitudes vs MICT at all time points, 24,25,33,34,42,43,75 with few exceptions. 32,44 These data support the established trend that SIT produces greater EPOC magnitudes than MICT protocols.…”

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.

“…In order to validate the test, criteria proposed by Howley et al (Howley et al, 1995) were followed and met by all participants. Additionally, as described by our laboratory (Schaun et al, 2017), the second ventilatory threshold (VT 2 ) was determined by visual inspection based on the ventilation vs. intensity graph and confirmed by the ventilatory CO 2 equivalent curve (Wasserman et al, 1973). Inter-observer intraclass correlation coefficient for VT 2 was r = 0.98.…”

Purpose: Even though multiple training methods appear to be effective to improve cardiorespiratory fitness, they also need to be perceived as tolerable or enjoyable by exercisers to maximize long-term behavioral maintenance. Therefore, the purpose of the current study was to compare perceived enjoyment between whole-body interval training (SIT-WB), treadmill-based interval training (SIT-T) and moderate-intensity continuous training (MICT). Method: Forty-one healthy adult men (age: 23.7 ± 0.7 years, height: 1.79 ± 0.01 m, body mass: 78.5 ± 1.7 kg; V̇O 2max : 46.7 ± 7.3 ml.kg −1 .min −1) were randomly assigned to SIT-WB, SIT-T, or MICT and underwent 16 weeks of training (3x/w). SIT-WB and SIT-T completed eight 20 s bouts interspersed by 10 s passive recovery, differing as to the exercise mode performed (i.e., calisthenics exercises and treadmill running, respectively) whereas MICT participants ran for 30 min at an intensity below the second ventilatory threshold. Perceived enjoyment was assessed 10 min post-exercise at weeks 1, 5, 9, 13, and 16, using the Physical Activity Enjoyment Scale. Results: Compliance was high (~90%) across all three training groups (p = .803). All training modes were rated as enjoyable and no significant within-(F (4, 152) = 1.132, p = .344) or between-group (F (2, 38) = 0.662, p = .521) differences were found during the intervention period. Conclusions: These results suggest that SIT-WB can be employed as an enjoyable low-cost alternative to traditional treadmill-based SIT and MICT for up to 16 weeks.

“…Oxygen is consumed during such high-intensity exercise. Several reports [35][36][37] have shown that excess post-exercise oxygen consumption (EPOC) values were higher in highintensity intervals or intermittent exercise groups compared to moderate aerobic exercise groups. Burleson et al 38) reported that V ・ O2 values during weight training and treadmill exercise were similar.…”

Enhanced exercise performance and anti-fatigue effects following L-citrulline (Cit) intake have been reported in resistance training and endurance exercise, but not in intermittent short-time high-intensity exercise. Therefore, the effect of Cit intake on intermittent short-time high-intensity exercise performance in collegiate athletes was investigated. A double-blind, placebo-controlled crossover trial was performed using nine male collegiate track athletes (age 20.9 ± 1.6 years). Each participant ingested either Cit or a placebo (3 g [grams]/day) for 7 days and underwent Wingate test using a bicycle ergometer on days 0 and 7 performed three times using a pedaling load of 7.5% of the participant's weight for 30 s (seconds) at full power. As for the results, Cit intake significantly increased the change in mean power output, pedaling speed per 5 s, and power output per 5 s (Δday 7 -0) during pedaling as well as the change in oxygen consumption derived by analysis of expired gas. The amount of change in the rate of perceived exertion during exercise significantly decreased, and the amount of change in serum nitrite/nitrate (NOx) (Δday 7 -0) post-exercise was significantly increased compared to that of pre-exercise by Cit intake. These results suggested that Cit intake of 3 g/day for 7 days may have enhanced exercise performance and anti-fatigue effects on intermittent short-time highintensity exercise in male collegiate track athletes.

Abstract: These data suggest that supramaximal HIIT has a higher impact on EE and EPOC in the early phase of recovery when compared to CONT.
