The present investigation evaluates a maximal anaerobic running test (MART) against the maximal accumulated oxygen deficit (MAOD) for the determination of anaerobic capacity. Essentially, this involved comparing 18 male students performing two randomly assigned supramaximal runs to exhaustion on separate days. Post warm-up and 1, 3, and 6 min postexercise capillary blood samples were taken during both tests for plasma blood lactate (BLa) determination. In the MART only, blood ammonia (BNH3) concentration was measured, while capillary blood samples were additionally taken after every second sprint for BLa determination. Anaerobic capacity, measured as oxygen equivalents in the MART protocol, averaged 112.2 ± 5.2 ml∙kg−1∙min−1. Oxygen deficit, representing the anaerobic capacity in the MAOD test, was an average of 74.6 ± 7.3 ml∙kg−1. There was a significant correlation between the MART and MAOD (r =.83, p <.001). BLa values obtained over time in the two tests showed no significant difference, nor was there any difference in the peak BLa recorded. Peak BNH3 concentration recorded was significantly increased from resting levels at exhaustion during the MART. Key words: supramaximal intermittent exercise, treadmill running performance, blood lactate, ammonia

The aim of the current study was to investigate the effects of acute caffeine supplementation on anaerobic capacity determined by the alternative maximal accumulated oxygen deficit (MAODALT) in running effort. Eighteen recreational male runners [29 ± 7years; total body mass 72.1 ± 5.8 kg; height 176.0 ± 5.4cm; maximal oxygen uptake (VO2max) 55.8 ± 4.2 ml·kg-1 ·min-1] underwent a graded exercise test. Caffeine (6 mg·kg-1) or a placebo were administered 1 hr before the supramaximal effort at 115% of the intensity associated with VO2max in a double-blind, randomized cross-over study, for MAODALT assessment. The time to exhaustion under caffeine condition (130.2 ± 24.5s) was 11.3% higher (p = .01) than placebo condition (118.8 ± 24.9 s) and the qualitative inference for substantial changes showed a very likely positive effect (93%). The net participation of the oxidative phosphorylation pathway was significantly higher in the caffeine condition (p = .02) and showed a likely positive effect (90%) of 15.3% with caffeine supplementation. The time constant of abrupt decay of excess postexercise oxygen consumption (τ1) was significantly different between caffeine and placebo conditions (p = .03) and showed a likely negative effect (90%), decreasing -8.0% with caffeine supplementation. The oxygen equivalents estimated from the glycolytic and phosphagen metabolic pathways showed a possibly positive effect (68%) and possibly negative effect (78%) in the qualitative inference with caffeine ingestion, respectively. However, the MAODALT did not differ under the caffeine or placebo conditions (p = .68). Therefore, we can conclude that acute caffeine ingestion does not modify the MAODALT, reinforcing the robustness of this method. However, caffeine ingestion can alter the glycolytic and phosphagen metabolic pathway contributions to MAODALT.

Anaerobic Work

This study first aimed to compare critical power (CP) and anaerobic work capacity (AWC), to laboratory standard evaluation methods such as maximal oxygen uptake (V̇O2max) and maximal accumulated oxygen deficit (MAOD). Secondly, this study compared child and adult CP and AWC values. Subjects performed a maximal graded test to determine V̇O2max and maximal aerobic power (MAP); and four constant load exercises. In children, CP (W.kg−1) was related to V̇O2max (ml.kg−1.min−1; r = .68; p = .004). AWC (J.kg−1) in children was related to MAOD (r = .58; p = .018). Children presented lower AWC (J.kg−1; p = .001) than adults, but similar CP (%MAP) values. CP (%MAP and W.kg−1) and AWC (J.kg−1) were significantly related to laboratory standard evaluation methods but low correlation indicated that they cannot be used interchangeably. CP (%MAP) was similar in children and adults, but AWC (J.kg−1) was significantly lower in children. These conclusions support existing knowledge related to child-adults characteristics.

The Relationship

The primary purpose of the study was to compare maximal accumulated oxygen deficit (MAOD) in resistance-trained (RT), endurance-trained (ET), and untrained men (UT). A secondary purpose was to determine the influence of leg muscle mass (MM) on MAOD by examining the relationship between MM and MAOD and by comparing MAOD expressed relative to MM between the groups. MAOD was determined during 2-4 min of constant-load fatiguing cycling. MM, estimated via anthropometric measurements, was higher (p <.05) for RT (mean ± SE; 25.5 ± 3.4 kg) compared to ET (20.3 ± 3.5) and UT (21.6 ± 3.4). MAOD in liters O2 eq was larger in RT (4.75 ± 0.3) compared to UT (3.07 ± 0.3) and ET (3.75 ± 0.3). A significant positive correlation was observed between MAOD (LO2 eq) and MM (kg) for RT only (RT, r =.85; ET, r =.55; UT, r =.20). Based on the correlational and mean MM data, the higher MAOD (LO2 eq) in RT relative to ET and UT is predominantly the result of their larger leg muscle mass.

AbstractThis study aimed to compare the Maximum Accumulated Oxygen Deficit determined by the conventional method (MAODC) with that determined by the backward extrapolation technique (MAODEXTR) in runners. Fourteen runners underwent a maximal incremental test for determination of iVO2MAX, ten submaximal efforts (50–95% of iVO2MAX for 7 min). During the submaximal efforts oxygen consumption (VO2) values were obtained conventionally and through the backward extrapolation technique (~ 3 s after the end of each effort). A supramaximal effort (110% of iVO2MAX) (tLimC) and five supramaximal bouts (tLimEXTR) were performed. MAODC and MAODEXTR were determined from the difference between the VO2 accumulated during tLimC and tLimEXTR and the predicted values. The tLimC was lower than tLimEXTR (164.06±36.32 s, 200.23±63.78 s, p<0.05). No significant differences were found between absolute and relative MAODC and MAODEXTR values, however, low intraclass correlations (0.26 and 0.24), high typical errors (2.03 L and 24 mL∙kg−1) were observed, and coefficients of variation (46 and 48%), respectively. The graphical analysis of the differences showed agreement and correlation between the methods (r=0.86 and 0.85). Thus, it can be concluded that the MAODEXTR is not a valid method for estimating the anaerobic capacity of runners, moreover, unreliable.

The Difference

This study examined whether accumulated oxygen deficit depends on treadmill grade during uphill running. Oxygen uptake was measured during steady-state submaximal running. By linear extrapolation at each grade, energy demand was estimated for short exhaustive runs. Oxygen deficit was the difference between this estimate and accumulated oxygen uptake. Six subjects ran at grades of 1, 15, and 20% (study I), and five males trained for anaerobic metabolism ran at 1, 10.5, and 15% (study II). Accumulated oxygen deficit was 40 +/- 11 (SD), 72 +/- 20, and 69 +/- 8 ml O2/kg, respectively (study I), and 57 +/- 8, 78 +/- 10, and 100 +/- 7 ml O2/kg (study II). The finding that accumulated oxygen deficit became larger with treadmill inclination could reflect involvement of an increasing muscle mass. However, variation in accumulated oxygen deficit was too large to make this possibility the only explanation. More likely at small treadmill inclinations energy demand for high-intensity running is underestimated by extrapolation from oxygen uptake during submaximal exercise. At high grades of uphill running, accumulated oxygen deficit reached a maximum that may reflect the subjects' anaerobic capacity for running. This hypothesis was substantiated by an enhanced accumulated oxygen deficit in the anaerobically trained subjects during 15%, but not during 1%, uphill running.
