Blood Lactate Levels

The purpose of the study was to compare the effect of creatine and thiamine supplementation on heart rate recovery (HRR) and blood lactate levels. Twelve male students comprised the two experimental (creatine and thiamine) groups of the study. The creatine group was supplemented with 0,3 g per weight, with 30 ml of water per dose of creatine four times a day, at regular intervals during the day, for 6 consecutive days. The thiamine group received 10 mg per weight just one time 30 minutes after a meal with 150 ml of water at the last supplementation days. After the supplementation period, subjects completed the incremental treadmill after a dynamic warm-up that consisted of walking at 6 km/h for 3 minutes. An initial treadmill speed started with 8,64 km/h for two minutes at 0% gradient followed by an increase of 1,44 km/h every 30 s until subjects reached their volitional exhaustion. After exercise cessation subjects continued with an active recovery of 10.08 km/h for approximately 5 minutes. Heart rate (HR) was regularly assessed from the first 5 min of passive recovery. Blood lactate levels were measured in the 9th min of passive recovery. There were no statistically significant differences in heart rate recovery and blood lactate levels after supplementation, respectively (P > 0.05). Based on these results, it appears that creatine supplementation did not provide a different effect with thiamine on the recovery of heart rate and blood lactate levels.

El objetivo de este estudio fue determinar en el pádel femenino de elite (PFE) las características antropométricas, la respuesta fisiológica y la estructura temporal producida durante una competición simulada (CS). Seis jugadoras con una experiencia mínima de 4 años en pruebas del circuito oficial fueron seleccionadas para participar en esta investigación. Se registraron diferentes medidas corporales para estudiar el perfil antropométrico: masa corporal, talla, 6 pliegues, 4 perímetros y 3 diámetros. Durante la CS fueron registradas las siguientes variables: i. Frecuencia cardíaca máxima (FCmáx), mínima (FCmín) y media (FCmed) de cada juego, set y total; ii. Niveles lácticos al terminar cada set, al finalizar el partido y en los minutos 2, 4, 6, 8 y 10 del periodo de recuperación; iii. Tiempo de juego total. Los valores antropométricos analizados reflejaron un somatotipo endo-mesomórfico (3.7-4.2-2.5). Los resultados fisiológicos obtenidos durante la CS fueron de 177±9.2 y 151±8.1 lpm para la FCmáx y FCmed respectivamente. Los niveles lácticos máximos alcanzados fueron de 2.4±.6 mmol.l. La duración media de los partidos fue de 56:11±00:38 m. La FCmáx fue de un 76.3% respecto a la máxima hallada en laboratorio. Los niveles de lactacidemia registrados situaron el esfuerzo en la vía metabólica aeróbica con cortos periodos entre el metabolismo aeróbico-anaeróbico. Conocer estos datos resulta de gran utilidad como método de control del rendimiento y de planificación del entrenamiento en el PFE.Palabras clave: composición corporal, somatotipo, lactato, frecuencia cardiaca, estructura temporal.Abstract: The aim of this study was to analyze anthropometric characteristics, physiological response and structure temporal produced in elite female paddle players (EFPP) during a simulated competition (SC). Six EFPP, with four years minimum experience in official circuit competitions, were selected for this study. Different body measures were registered to obtain the anthropometric profile: body mass, height, 6 skinfolds, 4 girths and 3 breadths. During CS the following variables were recorded: i. Maximum heart rate (HRmax), minimum and medium heart reat (HRmin and HRmed) on each game, set and final match; ii. Blood lactate levels after each set and lactate levels in minutes 2, 4, 6, 8, and 10 during recovery period; iii. Total playing time. Anthropometric values showed a mesoendomorfic somatotype (3.7-4.2-2.5). Physiological results showed that average achieved during SC was 177±9.2 and 151±8.1 bmp HRmax and HRmed, respectively. Maximum blood lactate levels showed by EFPP were 2.4±0.6 mMol.L-1. The mean match time was 56:11±00:38 m. Percentage of HRmax during simulated match was 76.3% of maximum value obtained during laboratory test. Blood lactate levels during SC showed that EFPP spent most of the time at aerobic intensities with brief periods at anaerobic intensities. Data obtained in this study provides useful information in EFPP training periodization and performance management.Key words: body composition, somatotype, blood lactate, heart rate, temporal structure.
