This paper deals with the measurement of aerobic and anaerobic power in children, and how these capacities are affected by growth and training. The type of tests available, the selection of ergometer, establishment of criteria for determining whether a maximal value has been attained, and the limitations of the various expressions of maximal values are discussed. Aerobic capacity, when expressed in liters per minute, has been observed to increase with growth; when expressed relative to body weight, aerobic capacity has been shown to remain the same or decrease with age. Anaerobic capacity increases with age no matter how the values are expressed. Limited evidence suggests that training during prepubescence does not increase aerobic capacity beyond that expected from growth. Several methodological limitations of longitudinal studies are examined.

Abstract Pacing strategies are used in cycling to optimize the power delivered by the cyclist during a race. Gains in race time have been obtained when using these strategies compared to self-paced approaches. For this reason, this study is focused on revising the effect that the variation of the cyclist’s parameters has on the pacing strategy and its results. A numeric method was used to propose pacing strategies for a cyclist riding on an ascending 3.7 km route with a constant 6.26% road grade. The method was validated and then implemented to study the effect of aerobic and anaerobic power delivery capacity, mass, and drag area on the pacing strategies and their corresponding estimated race times. The results showed that modifying 1% of the aerobic capacity or cyclist mass value led to a change of 1% on the race time. Modifying 1% the anaerobic capacity and the drag area led to changes of 0.03% and 0.02% on the race time, respectively. These results are strongly dependent on the route characteristics. It was concluded that for the studied route (constantly ascending), the variation of the cyclist’s aerobic capacity influences the pacing strategy (i.e., the power delivery over the distance). The anaerobic capacity and mass of the cyclist also influence the pacing strategy to a lesser extent.

The present study investigated the effects of β-alanine supplementation on the resultant blood acidosis, lactate accumulation, and energy provision during supramaximal-intensity cycling, as well as the aerobic and anaerobic contribution to power output during a 4000-m cycling time trial (TT). Seventeen trained cyclists (maximal oxygen uptake = 4.47 ± 0.55 L·min−1) were administered 6.4 g of β-alanine (n = 9) or placebo (n = 8) daily for 4 weeks. Participants performed a supramaximal cycling test to exhaustion (equivalent to 120% maximal oxygen uptake) before (PreExh) and after (PostExh) the 4-week supplementation period, as well as an additional postsupplementation supramaximal cycling test identical in duration and power output to PreExh (PostMatch). Anaerobic capacity was quantified and blood pH, lactate, and bicarbonate concentrations were measured pre-, immediately post-, and 5 min postexercise. Subjects also performed a 4000-m cycling TT before and after supplementation while the aerobic and anaerobic contributions to power output were quantified. β-Alanine supplementation increased time to exhaustion (+12.8 ± 8.2 s; P = 0.041) and anaerobic capacity (+1.1 ± 0.7 kJ; P = 0.048) in PostExh compared with PreExh. Performance time in the 4000-m TT was reduced following β-alanine supplementation (−6.3 ± 4.6 s; P = 0.034) and the mean anaerobic power output was likely to be greater (+6.2 ± 4.5 W; P = 0.035). β-Alanine supplementation increased time to exhaustion concomitant with an augmented anaerobic capacity during supramaximal intensity cycling, which was also mirrored by a meaningful increase in the anaerobic contribution to power output during a 4000-m cycling TT, resulting in an enhanced overall performance.

Abstract This study objective was to evaluate gender differences in hematological, hormonal and fitness variables among youth swimmers and to explore relationships between erythrocyte indices and aerobic and anaerobic capacity. 137 girls and 171 boys participated in the study and were divided into three groups based on their training experience. Blood samples were obtained to determine red blood cell counts, hemoglobin concentration, hematocrit, and plasma erythropoietin and testosterone levels. VO2max was assessed using a submaximal cycle protocol. 76 girls and 102 boys also undertook a Wingate test to determine their peak anaerobic power. Boys had higher (p < 0.05) means than girls for all hematological variables except for erythropoietin and these variables demonstrated an increase with training in boys. The average VO2max in l∙min-1 and peak anaerobic power in watts were also higher in boys (2.91 ± 0.08 and 547 ± 28, respectively) than girls (2.25 ± 0.07 and 450 ± 26, respectively). Modest but significant (p < 0.05) correlations were found between VO2max and red blood cell counts (r = 0.252), hemoglobin concentration (r = 0.345), or hematocrit (r = 0.345) and between peak anaerobic power and red blood cell counts (r = 0.304), hemoglobin concentration (r = 0.319) or hematocrit (r = 0.351). This study revealed relatively lower yet age- and gender-appropriate hematological, hormonal and fitness indices in youth swimmers. The gender-related differences in erythrocyte indices seem unrelated to erythropoietin and may be explained by the higher testosterone levels seen in boys. Given their correlation to both aerobic and anaerobic capacity, erythrocyte indices may be used as part of talent identification for sports.

The purpose of this study was to examine the aerobic and anaerobic capacities of professional American flamenco dancers in order to understand the energy requirements of this dance form. Eleven professional flamenco dancers from Albuquerque, New Mexico, provided a convenience sample (men = 4 and women = 7). There were three components to the testing: body composition measured with skinfold calipers, maximal aerobic capacity (VO2max) as determined by a graded exercise test with measured expired gases, and anaerobic capacity measured with a Wingate test. The mean age of the dancers was 28.45 years (24–44 years) and there was a mean of 13.5 years of performance experience (2–40 years). Both men and women were below average in terms of body composition, with a mean of 9.96% body fat (BF) for men (5.25– 13.09%BF) and 16.35%BF for women (12.96–20.17%BF). Mean maximum aerobic capacity was 51.63 mL · kg–1 · min–1 for men (40.7– 59.5 mL · kg–1 · min–1) and 38.78 mL · kg–1 · min–1 for women (32.9–43.8 mL · kg–1 · min–1), categorizing both as above average for their respective sexes. Results of the Wingate test gave a mean peak power of 16.2 W/kg (13.7–18.3 W/kg) and 11.3 W/kg (8.6–14.3 W/kg) for men and women, respectively; with a fatigue index of 65.5% (62–74%) for men and 56.1% (35.2–68.1%) for women. These results are nearly 25% higher than other published data on anaerobic athletes. Thus, flamenco dancers have a substantial anaerobic power output. Based upon the results of this study, it is suggested that the training of flamenco dancers include an aerobic and an anaerobic component.

Aerobic capacity is dominant factor of every individual for attaining dominating performance in sports particularly to achieve optimum performance in the endurance sports. The aim of study was to assess the aerobic capacity of the players of Athletics and rowing team of Islamabad. Aerobic and anaerobic exercises can be beneficial for the fitness and depending on the intensity, duration and events.  The mechanism of respiration and heart rate is differ in aerobic and anaerobic activities. Thirty athletes from middle and long distance events of track and field age group (23.9 ± 3.0) weight (64.13 ± 7.0) and thirty players of the rowing team age group (27.9 ± 4.1) weight (81.4 ± 8.7) from the Capital city Islamabad team were selected to investigate their aerobic capacity through the PACER (Progressive Aerobic Cardiovascular Endurance Run) test. The PACER     test for both teams was conducted at the same time and in the same conditions. The data were recorded and tabulated in respect of both the teams. The SPSS version 21 was used to analyze the data by applying individual sample t- test. It is concluded that Peak values of VO2 max of athletics team (58.81% ± 3% l/min), were significantly higher (p<0,005) than rowing team players which had (55.29 % ± 3%  l/min. Rowing players require higher degree of endurance for optimum achievements. The results indicated that peak values of VO2 max of athletics team is higher due to less body weight as compared to rowing team. Body weight has significant impact on aerobic capacity.

The purpose of this study was to evaluate the effect of glycine propionyl-Lcarnitine (GPLC) supplementation and endurance training for 8 wk on aerobicand anaerobic-exercise performance in healthy men and women (age 18–44 yr). Participants were randomly assigned to 1 of 3 groups: placebo (n = 9), 1 g/d GPLC (n = 11), or 3 g/d GPLC (n = 12), in a double-blind fashion. Muscle carnitine (vastus lateralis), VO2peak, exercise time to fatigue, anaerobic threshold, anaerobic power, and total work were measured at baseline and after an 8-wk aerobic-training program. There were no statistical differences (p > .05) between or within the 3 groups for any performance-related variable or muscle carnitine concentrations after 8 wk of supplementation and training. These results suggest that up to 3 g/d GPLC for 8 wk in conjunction with aerobic-exercise training is ineffective for increasing muscle carnitine content and has no significant effects on aerobic- or anaerobic-exercise performance.

<p>The aim of study was to analyze aerobic capacity and anaerobic power levels of the university students. Total forty university students who is department physical education and department business (age means; 21.15±1.46 years for male and age means; 20.55±1.79 years for female in department physical education), volunteered to participate in this study. Anaerobic power was measured with Running Anaerobic Sprint Test (RAST). Oxygen consumption was estimated 20-m shuttle run test. We found that was aerobic and minimum anaerobic capacity of physical education students higher than aerobic and minimum anaerobic capacity of business students (P&lt;0.05). On the other hand, we didn’t found differences between physical education female and male students and business female and male students in maximal anaerobic capacity and average anaerobic capacity (P&gt;0.05). We found that was aerobic and minimum anaerobic capacity of female and male students in department physical education higher than aerobic and minimum anaerobic capacity of female and male students in department of business (P&lt;0.05). In addition, fatigue index of female students in department physical education lower than fatigue index of female students in department of business was found (P&lt;0.05). In conclusion, recreational sportive activities affect development of aerobic capacity, depending on this, aerobic capacities of the students having education at the physical education and sport teaching department are more advanced than the students of the business management department due to applied courses included in the curriculum, in addition to recreational activities, genetic factors are determinants of anaerobic capacities.</p>

The effect of chronic metformin intake on aerobic and anaerobic capacity was examined in healthy rats. Twenty rats completed 10 days of metformin (MET) ingestion (250 mg). After this period, the animals performed four high-intensity bouts until exhaustion at 9%, 11%, 13%, and 15% of body mass (BM) in swimming, separated by 24 h, with prior metformin (250 mg) or placebo (PL). The critical load (CL) and anaerobic work capacity (AWC – W′) were calculated and considered aerobic and anaerobic capacity, respectively. There was no difference in CL between the MET and PL groups (p > 0.05). The AWC – W′ was higher in the MET group than in the PL group (p = 0.004). Time until exhaustion (seconds) at all bouts were higher (p < 0.004) in the MET group (9% of BM = 434.5 ± 267.3, 11% of BM = 269.6 ± 214.2, 13% of BM = 174.0 ± 40.9, 15% of BM = 146.6 ± 15.9) compared to the PL group (9% of BM = 96.4 ± 22.3, 11% of BM = 65.5 ± 13.4, 13% of BM = 51.1 ± 5.5, 15% of BM = 40.8 ± 7.5). Glucose concentration was higher at 90 and 120 min than at 0 and 30 min for the MET group (intragroup) during the oral glucose test tolerance; there was no difference between the MET and PL groups for area under curve. MET ingestion enhances AWC – W′ and times to exhaustion but not aerobic capacity.

The purpose of this study was to determine the development of physiological aspects of increasing aerobic and anaerobic performance in students who become badminton athletes through optimizing footwork exercises using the high-intensity interval method (HITT). This research will provide a solution for trainers in combining and optimizing footwork exercises as a technique in badminton combined with the principles of interval training to increase badminton athletes' aerobic and anaerobic capacity. This study used an experimental approach by giving footwork training treatment (HITT) to 30 Padang State University students who became badminton athletes. Researchers saw the effect of the exercise given on aerobic capacity (VO2max) and anaerobic capacity. The statistical analysis results showed that footwork exercise with The HIIT (High High-Intensity Interval Training) method positively affects badminton athletes' maximal aerobic capacity (VO2max) anaerobic capacity. In this concept, footwork training using the HIIT method effectively develops aerobic and anaerobic metabolism in response to energy requirements during total energy production in training maximum.
