Validity and reliability of a tower climb test for the assessment of anaerobic performance in urban firefightersClarke, Melissa 26 April 2012 (has links)
The purpose of this study was to determine the validity and reliability of an 8-flight tower climb test (TCT) to assess anaerobic performance in urban firefighters. Twenty-five professional urban firefighters participated in the validity testing of the TCT versus the Wingate Anaerobic Test (WAT) over 2 randomly sequenced testing sessions. Test-retest reliability was assessed separately in 21 active male and female participants over 2 TCT trials. During both validity and reliability testing for the TCT, participants ascended a firefighting training tower as fast as possible from a 1.7m running start while wearing firefighter protective equipment. Time was measured and power was calculated from the foot of the training tower to the top of the first (height = 1.75m) and eighth (height = 13.89m) flights of stairs. During the other session assessing TCT validity, participants completed a 30-second WAT using a resistance of 85gkg-1 body weight (BW). Several significant correlations were found including those between TCT power and: 1) mean WAT power generated for the duration equivalent to TCT time (r = 0.869), 2) peak power for the first 2 seconds of the WAT (r = 0.868), and 3) WAT peak power (r = 0.864). TCT test-retest performance in 21 active males and females showed that the test is highly reproducible. The mean time of completion of the 8-flight TCT was 21.81 + 5.03 seconds and 21.38 + 4.86 seconds for Trials 1 and 2, respectively. Intraclass correlations for time and power data from the first and eighth flights ranged from 0.94 to 0.99, and coefficients of variance ranged from 2.0% to 7.5%. These findings provide strong evidence that the TCT is a valid and reliable field-based assessment of occupation-specific anaerobic performance in urban firefighters. / Graduate

A Comparison of the Effects of High-Resistance Cycle Training and Leg Press on the Wingate Anaerobic Test, Strength, and Time-Trial PerformanceStites, Aaron W. 18 March 2009 (has links) (PDF)
The purpose of this study was to compare high-resistance cycle training (HRCT) with resistance training (RT), and their effects on Wingate anaerobic test watt max (Wmax) and watt average (Wave), strength (improvement in 1 repetition max [RM]), and time-trial performance. Twenty-five healthy college-age untrained male subjects were randomly assigned to the HRCT (n=10), RT (n=10), or control (n=5) group. All subjects completed pre and posttesting for the leg press (LP), 30 s Wingate anaerobic test, and 15-min time-trial. Subjects also completed familiarization tests prior to pretesting in the Wingate anaerobic test and 15-min time-trial. HRCT and RT subjects trained 2x/wk for 8 weeks with at least 48 hrs between training sessions. During each training session HRCT completed 4 x 30 sec efforts increasing resistance when >65 rotations per minute (rpm) could be maintained for the full training session. RT completed 3 x 10 repetitions of leg press with weight increasing 5 -10 lbs when all repetitions were completed during a training session. ANOVA with Tukey post-hoc was used to determine if differences existed between the groups. Within group change was analyzed using paired T-test. Effect size was computed to determine meaningfulness of differences. HRCT and RT groups both showed statistical significance (p < 0.05) pre to posttesting in LP, Wingate anaerobic test Wmax and Wave, and 15-min time-trial. Control group also showed statistical significance (p < 0.05) pre to posttesting in LP and 15-min time-trial. Significant between group differences were noted between HRCT and control in Wingate anaerobic test Wmax (p=0.03) and Wave (p = 0.007) and 15-min time-trial (p = 0.003). There was a significant difference between RT and control on the 15-min time-trial (p = 0.008). When comparing HRCT and RT no statistical difference was seen in LP, Wingate anaerobic test Wmax and Wave, and 15-min time-trial. High-resistance cycle training and RT resulted in similar strength gains. However, HRCT showed greater improvements in cycling specific activities: 30 s Wingate anaerobic test Wmax and Wave, and 15-min time-trial. Results suggested that HRCT may increase performance on bike related assessments when compared to RT.

Deguonies suvartojimo atliekant sunkėjantį krūvį pastovios fazės sąsaja su anaerobiniu pajėgumu / Oxygen consumption during increasing load constant phase interface with anaerobic capacityPukelevičiūtė, Asta 28 June 2011 (has links)
Pagrindiniai trys faktoriai lemiantys bėgikų ištvermę yra: maksimalus deguonies suvartojimas (MDS), laktato slenkstis (LS), bei bėgimo ekonomiškumas. Geriausi sportininkai turi panašų MDS, LS, bėgimo ekonomiškumą, bet įrodyta, kad raumenų faktoriai gali įtakoti ištvermę labiau, nei MDS. Yra duomenų, kad sportininkų raumenų galingumą įtakoja anaerobiniai adenozintrifosforo rūgšties (ATP) resintezės procesai, kurie gali turėti įtakos ir aerobinės ištvermės sportininkų varžybų rezultatams. Nustatyta, kad nuosekliai sunkėjančio krūvio (NSK) testo pabaigoje yra didesnis anaerobinis ATP resintezės indėlis. Vadinasi, didesnė raumenų masė ir jėga gali padėti toleruoti vis didėjantį ATP pareikalavimą ir parodyti didesnį deguonies suvartojimo pastovios fazės pasireiškimą. Labai įdomu būtų sužinoti, kaip anaerobinis pajėgumas gali įtakoti ilgų nuotolių bėgikų deguonies suvartojimo pastovios fazės trukmę. Mes manome, kad mūsų gauti tyrimo duomenys, leis geriau suprasti, kokį indėlį anaerobinis pajėgumas vaidina skirtingos deguonies suvartojimo pastovios fazės trukmės pasireiškime.
Tyrimo tikslas – Nustatyti deguonies suvartojimą atliekant sunkėjantį krūvį ir pastovios fazės sąsaja su anaerobiniu pajėgumu.
Tyrimo objektas: anaerobinio pajėgumo poveikis deguonies suvartojimo kaitai sunkėjančio krūvio metu.
Tyrimo uždaviniai:
1. Palyginti aerobinio ir anaerobinio pajėgumo rodiklius tarp bėgikų pasiekiančių ilgesnę ir trumpesnę pastovią fazę.
2. Nustatyti koreliacinį ryšį tarp aerobinių ir... [toliau žr. visą tekstą] / Key words: aerobic capacity, anaerobic test, blood lactate concentration, long – distance runners.
The three main factors determining runners endurance are: maximum oxygen consumption, lactate threshold and running economy. However, among the best sportsmen of similar maximum oxygen uptake, lactate threshold and running economy has been shown that muscular factors may influence the endurance more than the maximum oxygen consumption. There is evidence that the athletes' muscle power affects the ATP resynthesis anaerobic processes that may affect the aerobic and endurance sports events. showed that a consistent worsening at the end of the test is more anaerobic ATP contribution resynthesis, thus more muscle mass and strength can help to tolerate the increasing demand of ATP longer a burden, and to show increased oxygen consumption in stable phase of occurrence. It is interesting to learn how to influence the anaerobic capacity for long-distance runners' oxygen consumption in stable phase duaration. Therefore, our survey data to obtain a better understanding of the contribution of anaerobic capacity plays a different oxygen consumption constant phase term occurs.
The study objective – identify the oxygen uptake during increasing workload constant phase interface with the anaerobic capacity.
The object of the study – anaerobic capacity effects on the oxygen consumption change during increasing exercise load.
Study tasks:
1. To compare the aerobicand anaerobic capacity in... [to full text]

Estimativa dos metabolismos anaeróbios no déficit máximo acumulado de oxigênio / Estimating of anaerobic metabolisms for maximal accumulated oxygen deficitBertuzzi, Rômulo Cássio de Moraes 04 April 2008 (has links)
O objetivo desse estudo foi averiguar a possibilidade de se estimar os componentes anaeróbios do déficit máximo acumulado de oxigênio (MAOD) utilizando apenas o consumo de oxigênio (VO2). Adicionalmente, foi proposto um método alternativo que não necessita utilizar a extrapolação do VO2 do exercício submáximo para estimar a demanda de O2 para o exercício supramáximo. Para tanto, dez sujeitos fisicamente ativos foram submetidos aos seguintes testes: a) teste progressivo até a exaustão para determinar a carga correspondente ao consumo de oxigênio (WVO2max); b) seis testes de cargas constantes com intensidades abaixo da WVO2max (40-90% WVO2max); c) um teste a 110% da WVO2max; d) teste anaeróbio de Wingate. A fração do metabolismo anaeróbio alático foi estimada pela fase rápida do excesso do VO2 após o exercício (EPOCRÁPIDO), ao passo que a fração do metabolismo anaeróbio lático foi determinada tanto pela diferença entre MAOD e o EPOCRÁPIDO (MAODLA-1) como pelo acúmulo de lactato no sangue (MAODLA-2). O MAODMOD foi calculado pela somatória do EPOCRÁPIDO com MAODLA-2. Os principais resultados foram: a) as estimativas das contribuições do metabolismo anaeróbio lático não eram estatisticamente diferentes (MAODLA-1 = 2,40 ± 0,66 l; MAODLA-2 = 2,20 ± 0,4 l; p > 0,05); b) similarmente, os resultados do MAOD (3,03 ± 0,62 l) MAODMOD (2,84 ± 0,41) não eram significativamente diferentes (p > 0,05); c) foram detectadas correlações positivas entre MAODMOD, EPOCRÁPIDO, MAODLA-2 e os índices do teste de Wingate; d) os valores percentuais do EPOCRÁPIDO e do MAODLA-1 eram 22 ± 9% e 78 ± 9%, respectivamente. Esses resultados sugerem que os componentes anaeróbios do MAOD podem ser estimados satisfatoriamente utilizando somente o VO2 e que o MAOD pode ser determinado mediante MAODmod / The objective of this study was ascertain the possibility of estimate the anaerobic components of the maximal accumulated oxygen deficit (MAOD) used only oxygen uptake (VO2). In addition, was proposed an alternative method (MAODMOD) to determine the MAOD without using the extrapolation from submaximal VO2 to estimate the O2 demand of supramaximal exercise. Thus, ten subjects physically active performed the following tests: a) a maximal incremental exercise test for the measurement of the power output correspondent to maximal oxygen uptake (WVO2max); b) six submaximal tests with intensities bellow of the WVO2max (40-90% WVO2max); c) a supramaximal test at 110% WVO2max; d) Wingate anaerobic test. The fraction of the anaerobic alactic metabolism was calculated based on the fast component of excess post-exercise oxygen uptake (EPOCRÁPIDO), although the fraction of the anaerobic lactic metabolism was calculated based on both difference between MAOD and EPOCRÁPIDO (MAODLA-1) and changes in net blood lactate accumulation (MAODLA-2). MAODMOD was calculated by the sum of the EPOCRÁPIDO with the MAODLA-2. The main results were: a) non significant difference was found between the anaerobic lactic estimates (MAODLA-1 = 2,40 ± 0,66 l; MAODLA-2 = 2,20 ± 0,4 l; p > 0,05); b) similarly, there was no significant difference (p > 0,05) between MAOD (3,03 ± 0,62 l) and MAODMOD (2,84 ± 0,41); c) positive and significant correlation were detected between MAODMOD, EPOCRÁPIDO, MAODLA-2 and the indices of the Wingate anaerobic test (p < 0,05); d) the mean of the percentage values of the EPOCRÁPIDO and MAODLA-1 were 22 ± 9% e 78 ± 9%, respectively. These data suggest that the anaerobic components of the MAOD can be satisfactorily estimated using only the VO2 and that the MAOD can be determined using the MAODmod
