Extent of Lactic Anaerobic Metabolism in Handballers

Abstract

The authors investigated lactic anaerobic metabolism in handball players during practice games. Seven players aged 18-21, belonging to second division league clubs, took part in the study. In the laboratory, VO2 max and the onset of blood lactate accumulation (OBLA) were determined with progressive maximal ergocycle tests. On the field, video recordings, cardiotelemetry, and rectal temperature measurements made during the first half of the game were used to quantify exertion. An intravenous catheter worn permanently was used to draw blood for lactate measurements at the 5th, 10th, 15th, 20th, and 30th min of play and after a 10-min rest period. The results confirmed earlier observations showing the need for an excellent maximal aerobic power and capacity in handballers. However, the maximal lactate levels observed (4-9 mmol X l-1) were above those that could be expected from samples drawn only at the end of play. These findings indicate that players must be trained to tolerate high lactate levels to preserve their maximal efficiency throughout the game. Finally, lactate production increased with player exertion and with increasing OBLA.

A multidisciplinary approach of success in team-handball

“…Nevertheless, significant differences between groups were observed in five physiological evaluations, i.e. the successful team-handball athletes recorded (i) higher values for sit-ups, (ii) faster times over the 30-m sprint, and (iii) lower values on dynamometry tests (handgrip 27 has reached the conclusion that the maximal aerobic power and capacity are prerequisites to the achievement of excellence in team-handball (age 18---21 years), and more recently Gorostiaga et al 28 concluded that endurance capacity does not seem to be a limiting factor for elite performance in team-handball. In fact, our results suggest that team-handball players may not need to have an extraordinary aerobic capacity, but they must possess a reasonably high level aerobic capacity.…”

Determinações e relações dos parâmetros anaeróbios do RAST, do limiar anaeróbio e da resposta lactacidemica obtida no início, no intervalo e ao final de uma partida oficial de handebol

“…Alguns estudos (6,7,9) foram realizados com o intuito de determinar a capacidade aeróbia de atletas de handebol, no entanto, nenhum deles apresentou os resultados referentes ao limiar anaeróbio (km.h -1 ). Delamarche et al (9) constataram em cicloergômetro que o consumo de oxigênio no OBLA (Onset of Blood Lactate Concetration) foi de 3,53 ± 0,22 L.min -1 .…”

Gorostiaga et al (6) estudaram o efeito de 6 semanas de treinamento de resistência nas concentrações de lactato sanguíneo referentes as velocidades de 10 e 11 km.h -1 em handebolistas adolescentes (15,1 ± 0,7 anos).…”

“…Delamarche et al (9) constataram que a concentração pico de lactato sanguíneo durante uma partida de handebol foi de 6,73 ± 1,81 mM e que esse valor esteve acima da [Lac] referente ao OBLA (4mM).…”

“…Embora exista uma vasta literatura internacional que objetivou contemplar diversos aspectos do handebol como força máxima (6) e explosiva (6,7) , consumo máximo de oxigênio (8,9) , e capacidade aeróbia (6,7,9) , em nível nacional, muito pouco tem sido realizado para caracterização fisiológica dos atletas dessa modalidade esportiva.…”
