“…A possible explanation could be related to the differences between the two methods of determination of the anaerobic metabolism. The MAOD ALT is based on the sum of the oxygen equivalents corresponding to glycolytic and phosphagen pathways estimated during the supramaximal effort 5 8 19 20 . The latter takes into account an energetic equivalent expressed relative to the individual’s body mass (i.e.…”

“…The MAOD ALT seems to be an advantageous tool for use during routine training because it allows the estimation of anaerobic capacity in only one supramaximal exercise session. Furthermore, the MAOD ALT allows discrimination of the glycolytic and phosphagen metabolisms, enabling analysis of the specific responses in each metabolism 23 and it can be considered a sensitive enough procedure to distinguish the “anaerobic” capacity in individuals with different training levels 19 . Regarding the reliability, although the points obtained from the differences between MAOD ALT values are distributed around the systematic error, there was a limit of agreement in test-retest corresponding to ±0.54L ( Fig.…”

The aim was to verify the validity (i.e., study A) and reliability (i.e., study B) of the alternative maximal accumulated oxygen deficit determined using onlya supramaximal effort (MAODALT)to estimate anaerobic capacity [i.e., estimated by the gold standard maximal accumulated oxygen deficit method (MAOD)] during cycling. In study A, the effects of supramaximal intensities on MAODALT and the comparison with the MAOD were investigated in fourteen active subjects (26 ± 6 years). In study B, the test-retest reliability was investigated, where fourteen male amateur cyclists (29 ± 5 years) performed the MAODALT twice at 115% of the intensity associated to maximal oxygen uptake (). MAODALT determined at 130 and 150% of was lower than MAOD (p ≤ 0.048), but no differences between MAODALT determined at 100, 105, 110, 115, 120 and 140% of (3.58 ± 0.53L; 3.58 ± 0.59L; 3.53 ± 0.52L; 3.48 ± 0.72L; 3.52 ± 0.61L and 3.46 ± 0.69L, respectively) with MAOD (3.99 ± 0.64L). The MAODALT determined from the intensities between 110 and 120% of presented the better agreement and concordance with MAOD. In the test-retest, the MAODALT was not different (p > 0.05), showed high reproducibility when expressed in absolute values (ICC = 0.96, p < 0.01), and a good level of agreement in the Bland-Altman plot analysis (mean differences ± CI95%:−0.16 ± 0.53L). Thus, the MAODALT seems to be valid and reliable to assess anaerobic capacity in cycling.

“…To eliminate any influence of circadian variation, each subject completed all trials at the same time period of day in controlled environmental conditions regarding temperature (22.9 ± 1.3°C) and relative humidity (43.8 ± 6.3%). In all efforts, participants were verbally encouraged to perform maximally and wore a chest harness with the rope attached to the ceiling to ensure maximal effort without fall risk (except the 30-s ATR) [ 13 , 15 ]. Prior to each exercise trial, the subjects responded to the profile of mood states scale to measure their motivation for the effort.…”

“…Recently Zagatto et al [ 13 ] reported the validity, reliability and reproducibility of the MAOD ALT for estimating the anaerobic capacity in treadmill running, evidencing that exercise intensity at 115% of maximal oxygen uptake (iVO 2max ) is the greatest intensity for MAOD ALT determination. In addition, this same group of authors recently reported that MAOD ALT assessed in treadmill running can be considered a sensitive enough procedure to distinguish the anaerobic capacity in individuals with different training levels (untrained, moderately active, recreational endurance runners and elite rugby sevens players) [ 15 ]…”

The purpose of the current study was to investigate the relationship between alternative anaerobic capacity method (MAODALT) and a 30-s all-out tethered running test. Fourteen male recreational endurance runners underwent a graded exercise test, a supramaximal exhaustive effort and a 30-s all-out test on different days, interspaced by 48h. After verification of data normality (Shapiro-Wilk test), the Pearson’s correlation test was used to verify the association between the anaerobic estimates from the MAODALT and the 30-s all-out tethered running outputs. Absolute MAODALT was correlated with mean power (r = 0.58; P = 0.03), total work (r = 0.57; P = 0.03), and mean force (r = 0.79; P = 0.001). In addition, energy from the glycolytic pathway (E[La-]) was correlated with mean power (r = 0.58; P = 0.03). Significant correlations were also found at each 5s interval between absolute MAODALT and force values (r between 0.75 and 0.84), and between force values and E[La-] (r between 0.73 to 0.80). In conclusion, the associations between absolute MAODALT and the mechanical outputs from the 30-s all-out tethered running test evidenced the importance of the anaerobic capacity for maintaining force during the course of time in short efforts.

“…The AC [La−]+EPOCfast is an advantageous method for anaerobic capacity assessment and its validity has been demonstrated by the absence of significant differences with the conventional MAOD determined in cycling ( 6 , 7 ), running ( 8 ), and table tennis ( 12 , 13 ). Furthermore, AC [La−]+EPOCfast method has shown high reliability (intraclass correlation coefficient [ICC] = 0.87 and typical error = 0.27 L) and significant associations with mechanical variables assessed in a 30 s maximal effort ( 14 ), besides to be sensitive in distinguishing individuals with different physical conditioning status ( 15 ).…”

The aim of this study was to verify the effects of caffeine on anaerobic capacity estimated by the sum of the estimated glycolytic [E[La]] and phosphagen [EPCr] metabolism based on blood lactate and excess post-oxygen consumption responses (AC[La−]+EPOCfast). Fourteen male cyclists were submitted to a graded exercise test to determine the maximal oxygen uptake (trueV°O2max) and intensity associated withtrue V°O2max (itrueV°O2max). Subsequently, the participants performed two supramaximal efforts at 115% of itrueV°O2max to determine the AC[La−]+EPOCfast, after previous supplementation with caffeine (6 mg·kg−1) or a placebo (dextrose), in a cross over, randomized, double blind, and placebo-controlled design. The time to exhaustion was higher in the caffeine (186.6 ± 29.8 s) than in the placebo condition (173.3 ± 25.3 s) (p = 0.006) and a significant correlation was found between them (r = 0.86; P = 0.00008). Significant differences were not found between AC[La−]+EPOCfast values from the placebo (4.06 ± 0.83 L and 55.2 ± 5.7 mL·kg−1) and caffeine condition (4.00 ± 0.76 L and 54.6 ± 5.4 mL·kg−1); however, a significant correlation was observed only for AC[La−]+EPOCfast expressed in absolute values (r = 0.74; p < 0.002). The E[La] and EPCr also presented no significant differences and they were significantly correlated (r = 0.82 and r = 0.55, respectively; p < 0.05). We conclude based on the overall comparison of mean values between two treatments that acute caffeine ingestion improves the time to exhaustion but does not affect anaerobic capacity estimation.
