Heart rate, blood lactate concentration, and time–motion analysis of female basketball players during competition

El principal objetivo del estudio fue analizar la intensidad de juego en jugadores de baloncesto en silla de ruedas (BSR) durante los partidos de play-off. En este estudio participaron nueve jugadores masculinos de BSR de primera división (34,8 ± 7,8 años). En total se analizaron seis partidos y los participantes fueron divididos en tres grupos según los minutos jugados: jugadores que jugaron 30-40 minutos (BSR30-40), jugadores que jugaron 20-29 minutos (BSR20-30) y los que jugaron entre 1 segundo y 19 minutos (BSR1-19). Durante todos los partidos se monitorizó la frecuencia cardíaca (FC), y además, se obtuvo la temperatura timpánica y la concentración de lactato sanguíneo antes e inmediatamente después de cada partido. Se encontraron diferencias significativas (P<0,05) en todas las zonas de intensidad entre el grupo BSR30-40 y BSR1-19. Los jugadores BSR30-40 pasaron un 36,4% del tiempo total por encima del 85% de la FCmáx, mientras que los jugadores BSR20-30 y BSR1-19 solo pasaron un 16,1 y un 9,2% del tiempo total. En todos los grupos tanto la temperatura timpánica (1,5-2,0%, P<0,05) como la concentración de lactato (81,1-125,0%, P<0,05) aumentó significativamente. Los resultados obtenidos en nuestro estudio exponen que los jugadores del grupo BSR30-40 pasaron mayor porcentaje de tiempo a alta intensidad (>85% de la FCmáx), con un aumento significativo de la temperatura y la concentración de lactato sanguíneo. Los entrenadores y preparadores físicos deberían tener en cuenta estas diferencias fisiológicas en función de los minutos jugados a la hora de planificar la temporada y los descansos post partido.Abstract. The main objective of the study was to analyze the game intensity in wheelchair basketball players (WB) during play-off matches. This study involved nine WB players of Spanish first division league (34.8 ± 7.8 years). Six play-off matches were analyzed and participants were divided into three groups according to the minutes they had played: players who had played between 30-40 minutes (WB30-40), players who had played between 20-30 minutes (WB20-30) and players who had played between 1 second and 20 minutes (WB1-19). For every game the heart rate (HR) was monitored by telemetry, and in addition, the tympanic temperature and blood lactate concentration samples were obtained before and immediately after each match. Significant differences (P<0.05) were observed in all intensity zones between WB30-40 and WB1-19 groups. The WB30-40 players spent 36.4% of the total time over 85% of maximum HR, while WB20-30 and WB1-19 players only spent 16.1 and 9.2% of the total time. Moreover, in all groups both tympanic temperature (from 1.5 to 2.0%, P<0.05) and lactate concentration (81.1 to 125.0%, P <0.05) increased significantly. The game intensity monitored by HR is different for WB players according to the minutes they had played (WB30-40, WB20-30 and WB1-19). The results of our study showed that the WB30-40 group obtained higher percentage of time spent at high intensity (> 85% of maximum HR) than other groups, with a significant increase in body temperature and blood lactate concentration. Coaches and physical trainers should be aware of these physiological differences when planning the season and post-match sessions.

Motion Characteristics

Purpose:To quantify the physiological responses, time–motion characteristics, and reproducibility of various speed-endurance-production (SEP) and speed-endurance-maintenance (SEM) drills.Methods:Sixteen elite male youth soccer players completed 4 drills: SEP 1 v 1 small-sided game (SSG), SEP running drill, SEM 2 v 2 SSG, and SEM running drill. Heart-rate response, blood lactate concentration, subjective rating of perceived exertion (RPE), and time–motion characteristics were recorded for each drill.Results:The SEP and SEM running drills elicited greater (P < .05) heart-rate responses, blood lactate concentrations, and RPE than the respective SSGs (ES 1.1–1.4 and 1.0–3.2). Players covered less (P < .01) total distance and high-intensity distance in the SEP and SEM SSGs than in the respective running drills (ES 6.0–22.1 and 3.0–18.4). Greater distances (P < .01) were covered in high to maximum acceleration/deceleration bands during the SEP and SEM SSGs than the respective running drills (ES 2.6–4.6 and 2.3–4.8). The SEP SSG and generic running protocols produced greater (P < .05) blood lactate concentrations than the respective SEM protocols (ES 1.2–1.7). Small to moderate test–retest variability was observed for heart-rate response (CV 0.9–1.9%), RPE (CV 2.9–5.7%), and blood lactate concentration (CV 9.9–14.4%); moderate to large test–retest variability was observed for high-intensity-running parameters (CV > 11.3%) and the majority of accelerations/deceleration distances (CV > 9.8%) for each drill.Conclusions:The data demonstrate the potential to tax the anaerobic energy system to different extents using speed-endurance SSGs and that SSGs elicit greater acceleration/deceleration load than generic running drills.

Background: The aim of the present study was to assess physiological-biochemical reactions to incremental exercise loads and the levels and development of endurance skills in young male and female team game players. Material/Methods: The study sample comprised 370 soccer, handball, basketball and volleyball players (186 girls and 184 boys) from the Lower Silesian Regional Teams in Poland, aged 14.20 ±1.37 years (boys) and 13.90 ±1.15 years (girls). The exercise test consisted ofthe shuttle run Beep Test for estimation of aerobic fitness. The assessment of endurance skills was based on the length of the covered distance in the Beep Test as well as on measurements of the heart rate (physiological) and blood lactate concentration (metabolic). Results: Among the four studied groups of players a statistically significant improvement in endurance skills was noted in male volleyball players (p ≤ 0.05). Conclusions: Significantly higher levels of endurance skills in young male handball, basketball and volleyball players and in female volleyball players who remained on the regional teams for two consecutive years may be an indication of the players’ proper selection and training. Significant changes in blood lactate concentration in young players, revealed in both cross-sectional and continuous studies, were only noted in male volleyball players. Significant decreases in the heart rate in the cross-sectional study was found only in male handball and basketball players and in female basketball players, whereas in the continuous study only in male handball players. An assessment of young players’ physiological-biochemical reactions on the basis of exercise test results can effectively enhance the optimization of training loads.

We investigated the match demands (distances covered and acute physiological responses) of amputee soccer and its impact on muscular endurance and power. Measures such as heart rate, blood lactate concentration, subjective rating of perceived exertion, and time-motion characteristics were recorded in 16 Brazilian amputee soccer players during matches. Before and after matches, players completed a battery of tests: push-ups, countermovement vertical jump performance, and medicine ball throwing. Small differences were found between the first and second half for the distance covered in total and across various speed categories. Heart rate responses, blood lactate concentrations, and peak speed did not differ between halves, and all neuromuscular performance measures decreased after the match particularly after push-ups, although the rating of perceived exertion increased markedly compared with prematches. Although match physical performances were consistent across halves, the overall demands impaired test performance, especially for upper limb and closed kinetic chain exercise.

The purpose of this study was to examine the effects of a 2-km swim on markers of subsequent cycling performance in well-trained, age-group triathletes. Fifteen participants (10 males, five females, 38.3 ± 8.4 years) performed two progressive cycling tests between two and ten days apart, one of which was immediately following a 2-km swim (33.7 ± 4.1 min). Cycling power at 4-mM blood lactate concentration decreased after swimming by an average of 3.8% (p = 0.03, 95% CI −7.7, 0.2%), while heart rate during submaximal cycling (220 W for males, 150 W for females) increased by an average of 4.0% (p = 0.02, 95% CI 1.7, 9.7%), compared to cycling without prior swimming. Maximal oxygen consumption decreased by an average of 4.0% (p = 0.01, 95% CI −6.5, −1.4%), and peak power decreased by an average of 4.5% (p < 0.01, 95% CI −7.3, −2.3%) after swimming, compared to cycling without prior swimming. Results from this study suggest that markers of submaximal and maximal cycling are impaired following a 2-km swim.
