“…In human athletes, an active 'warm down' period has been advocated to increase the rate of efflux of lactate from skeletal muscle to blood (Gisolfi et af. 1966;Evans and Cureton 1983). Other investigators have examined the effects of various levels of post exercise activity on the rates of blood lactate clearance (Hermansen and Stensvold 1972;Dodd et af.…”

Summary We determined the effect of post exercise activity on recovery from maximal exercise. Five Standardbred horses were exercised on an inclined treadmill (+10% slope) for 2 min at 2.5 m/s followed by 2 min at 12.5 m/s (∼110% V̇O2max). They had one of 3 recovery regimens: standing on the treadmill (A), trotting at 4 m/s for 15 min followed by walking at 2 m/s for 15 min (B), or walking at 2 m/s for 30 min (C). Muscle biopsies from the m. gluteus medius and jugular blood for blood lactate determination were collected, before and after exercise and at 3, 5, 10, 15, 20 and 30 min recovery. Ten minutes after exercise, heart rate was significantly (P<0.05) higher with recoveries B and C than recovery A, but there were no differences at 20 or 30 min following exercise. Both muscle and rectal temperatures were significantly (P<0.01) lower with recovery A compared with recoveries B and C. The type of recovery had no influence on the rate of change of [ATP] or [G‐6‐P]. The rate of decrease in plasma and muscle [lactate] was significantly faster with recovery B than A (P<0.05). Creatine phosphate increased (P<0.05) at a faster rate with recoveries B and C than A. We conclude that ‘warm‐down’ periods enhance clearance of lactate from skeletal muscle and that lactate may be utilised as a substrate by muscle during recovery from exercise.

“…There is good agreement that, within limits (Boileau et al, 1983), an active recovery promotes the removal of blood lactate better than a resting recovery (Belcastro and Bonen, 1975;Bonen and Belcastro,m 1976;Evans and Cureton, 1983;Hermansen and Stensvold, 1972;Stamford et al, 1981;Weltman et al, 1979). This effect can be attributed to the greater turnover and metabolic clearance rate of LA during moderate exercise (Issekutz et al, 1976).…”

“…However, when exercise is performed after blood lactate has been elevated, there is an increased lactate uptake (Belcastro and Bonen, 1975;Bonen and Belcastro, 1976;Evans and Cureton, 1983;Stamford et al, 1981;Weltman et al, 1979). Intensity of recovery exercise (Hermansen and Stensvold, 1972;Sharp, 1982), type of exercise (Belcastro and Bonen, 1975;Bonen and Belcastro, 1976), training status (Andersen and Henriksson, 1977), and type of muscle fibre Lamb, 1978), are thought to influence blood lactate removal.…”

Three tests were conducted to assess the effectiveness of three different intensities of exercise both in reducing blood lactic acid (LA) levels and in influencing subjects' heart rate (HR), following a 2000 m race in a rowing boat. In the first and second tests these variables were investigated during a 13 min recovery exercise at 60% and 40% of the preceding maximum rowing speed respectively. In the third test the subjects had a resting recovery.The results include a significant increase (P < 0.001) in the rate of lactate removal following the 40% recovery compared with the 60% and resting recoveries. The HRs were significantly lower during the last minute of resting recovery compared with 40% and 60% recoveries (P < 0.001). The same was true when 40% recovery was compared with 60% recovery (P < 0.001).The present data suggest firstly that 40% of the maximum rowing speed is an appropriate pace for effective LA removal and secondly that, at least for trained rowers, 86% of their maximum HR can be taken as an indication of work of an intensity at or above anaerobic threshold.

“…As formas de coleta, armazenamento e análise do lactato, foram as mesmas empregadas durante a determinação do LAn. Foi utilizada a regressão linear entre o logaritmo (base 10) da concentração de lactato e o tempo da recuperação, para o cálculo do meio tempo (t 1/2) da remoção do lactato sangüíneo (Evans & Cureton, 1983;McLellan & Skinner, 1982;Stamford, Weltman, Moffatt, & Sady, 1981).…”

O objetivo deste estudo foi verificar os efeitos, durante a recuperação passiva (RP), do tipo de exercício realizado previamente (corrida ou natação) e da capacidade aeróbia, determinada através do limiar anaeróbio (LAn), sobre a taxa de remoção do lactato sangüíneo (RLS), após um exercício de alta intensidade. Participaram do estudo nove indivíduos ativos do sexo masculino (20,66 + 3,24 anos; 1,76 + 0,04 m e; 71,22 + 4,26 kg). O LAn foi determinado medindo-se a concentração de lactato (YSL 2300 STAT) após cada tiro nos testes de corrida (3 x 1200 m progressivos) e de natação (3 x 200 m progressivos). A velocidade de cada exercício correspondente a 4 mM (LAn) foi calculada por interpolação linear. A seguir, os indivíduos realizaram em dias diferentes, duas sessões experimentais: corrida - 2 x 200 m na máxima velocidade, com 2 min de intervalo entre as tentativas; natação - 2 x 50 m na máxima velocidade, com 2 min de intervalo entre as tentativas. Cada procedimento deste foi seguido por 30 min de RP Após um, sete, 12, 17 e 30 min do término do exercício de alta intensidade, foram coletados 25 pl de sangue para a medição do lactato. Utilizando-se a regressão linear entre o logaritmo da concentração de lactato e o tempo da recuperação, foi calculado o meio tempo (t 1/2) da RLS. A RP após a corrida (CP = 25,5 min), apresentou um t 1/2 significantemente maior do que a RP após a natação (NP = 18,6 min). O t 1/2 das seqüências CP e NP, não correlacionaram-se com a velocidade correspondente ao LAn, obtida respectivamente na corrida (r = -0,18) e na natação (r = -0,57). Houve correlação significante entre os t 1/2 das seqüências CP e NP (r = 0,77). Com base nestes resultados, pode-se concluir que a capacidade aeróbia, determinada através do LAn, parece não influenciar a velocidade de RLS durante a RP. Durante a RP, a velocidade de remoção do lactato sangüíneo é menor após o exercício de corrida do que de natação
