Purpose:To examine the physiological profiles of wheelchair basketball and tennis and specifically to: (a) identify if there are differences in the physiological profiles of wheelchair basketball and tennis players of a similar playing standard, (b) to determine whether the competitive physiological demands of these sports differed (c) and to explore the relationship between the blood lactate [Bla−] response to exercise and to identify the sport specific heart rate (HR) training zones.Methods:Six elite athletes (4 male, 2 female) from each sport performed a submaximal and VO2 peak test in their sport specific wheelchair. Heart rate, VO2, and [Bla−] were measured. Heart rate was monitored during international competitions and VO2 was calculated from this using linear regression equations. Individual HR training zones were identified from the [Bla–] profile and time spent within these zones was calculated for each match.Results:Despite no differences in the laboratory assessment of HRpeak, the VO2peak was higher for the basketball players when compared with the tennis players (2.98 ± 0.91 vs 2.06 ± 0.71; P = .08). Average match HR (163 ± 11 vs 146 ± 16 beats-min–1; P = .06) and average VO2 (2.26 ± 0.06 vs 1.36 ± 0.42 L-min-1; P = .02) were higher during actual playing time of basketball when compared with whole tennis play. Consequently, differences in the time spent in the different training zones within and between the two sports existed (P < .05).Conclusions:Wheelchair basketball requires predominately high-intensity training, whereas tennis training requires training across the exercise intensity spectrum.

abstract The aim of this study was to examine the physiological demands of seven referees during a national basketball competition. We recorded heart rate (HR), relative exercise intensity as a percentage of age – predicted maximum HR (HRmax), proportion of playing time within the exercise intensity categories defined by the ACSM during each of the tournament matches for each referee per period, as well as the entire game. None of the variables shows significant differences between periods. Based on a format of three referees per match, referees worked with an average HR of 150 bpm (range 110-181 bpm) for each quarter of the match, which equals a relative intensity> 70% of HRmax for most (∼76%) of each quarter. Other studies will assist in developing appropriate training programs for elite basketball referees to maintain and / or maximize performance.

The purpose of this study was to examine the physiological changes in elite wheelchair basketball players leading up to the 2000 Paralympics. Twelve male players attended regular physiological assessments on six occasions; averaged data of two sessions for each year were used. Physiological measures included body mass, skinfold measurements, peak oxygen uptake and peak power obtained during maximal sprinting. VO2peak significantly increased from 2.65 to 2.83 L·min-1 prior to the Paralympics. Training had little influence on the anthropometric measurements or maximal sprinting data. In conclusion, the GB wheelchair basketball players appeared to have high levels of aerobic and anaerobic fitness. The longitudinal physiological profiles leading to the 2000 Paralympics suggest that players improved their aerobic base while maintaining other fitness prerequisites.

Abstract The purpose of this study was to investigate the effects of serve and return game situations on physiological responses and match characteristics in professional male tennis players during one hour-long simulated singles tennis matches. Ten internationally ranked tennis players (age 22.2 ± 2.8 years; body height 180.7 ± 4.4 cm; body mass 75.9 ± 8.9 kg) participated in this study. Their physiological responses were measured using two portable analyzers during indoor hard court matches. Ratings of perceived exertion were also determined at the end of the game. The variables describing the characteristics of the matches determined from video recordings were: (a) duration of rallies; (b) rest time; (c) work-to-rest ratio; (d) effective playing time; and (d) strokes per rally. Significant differences (p<0.05) were found between serving and returning conditions in an hour-long simulated singles tennis match in terms of oxygen uptake, a heart rate, ratings of perceived exertion, pulmonary ventilation, respiration frequency and a respiratory gas exchange ratio. In addition, both the heart rate and ratings of perceived exertion responses were moderately correlated with the duration of rallies and strokes per rally (r = 0.60 to 0.26; p<0.05). Taken together, these results indicate that the serve game situation has a significant effect on the physiological response in an hour-long simulated tennis match between professional male tennis players. These findings might be used for the physiological adaptations required for tennis-specific aerobic endurance.

The study compares intensity of game load among individual players’ positions and between first and second half. Ten female basketball players in senior category participated in this study. Four intensity zones were determined based on maximal heart rate (HRmax). Telemetric device Suunto Team Pack was used for monitoring the heart rate (HR) during the games. The mean HR during the games reached 88.1±3.9% of HRmax of total time. When we compared players’ positions in individual intensity zones we did not record statistical (p>0.05) nor practical significance and neither in % of HRmax (87.4±3.6 vs. 87.8±4.6 vs. 88.8±3.5; point guard vs. forward vs. center). Moreover, when we compared the 1st and the 2nd half in individual zones and in % of HRmax (87.7±4.1 vs. 88.5±3.7) we also did not record any statistical significance (p>0.05) and effect size coefficient shows small effect. Players spent 76.3% of total time with HR grater than 85% of HRmax. The results indicate high physiological demands on female basketball players during the games without taking into consideration the player’s position. This information can be useful for planning and managing training process as well as for comparison with training load. In similar future research we recommend to also evaluate the time-motion analysis besides the internal response and thus a more detailed look at the examined subject in question may be reached.

In wheelchair basketball the evaluation of the quality of disabled players’ movement, motion and action variety, sensomotoric, intelectual, social interaction skills, coordinative and physical abilities besides the natural tests (Brasile, 1986), quantitative and qualitative play results (technical actions carried out by a player during a game and during a minute of a game) are considered to be objective and informative. The aim of the research was to state and evaluate the playing skills of wheelchair basketball players in different game positions (a playmaker, a forward, a center) in official competitions. The play of 32 baketball players was under research. Aiming to analyse playing results of wheelchair basketball players in different game positions 20 games were video recorded by camera ”Panasonic NV-GS27“. The following actions of the players (playmakers, forwards, centers) with different functions in the team were recorded: playing time, passing, dribbling, shooting and its efficiency, rebounding and other important technical actions characterizing the activity of the players during the game. The integral preparation, ability to play, the playing quality were evaluated according to the methods of D. Byrnes and B. Hendrick (1994), giving high or low marks for each action. Results showed that centers were the most active ones, carrying out on average 2.5 actions per minute (forwards — 2.1, playmakers — 1.2), shooting 16 times per game (forwards — 7.7, playmakers — 5). The most universal players were also the centers, their passing and dribbling actions making up 25%, shooting actions — 20% of all the movements. The most accurate main technical actions were carried out by the centers: their shooting accuracy was 36% (that of wing players and playmakers being 30%). Centers’ integral qualification and playing skills (according to the methods used) were the highest rated + 42 points. Quantitative and qualitative playing results and the results of integral preparation of wheelchair basketball players in center position were significantly better than those of the playmakers and forwards.Keywords: wheelchair basketball, quantitative and qualitative playing results, integral qualification, player’s game positions.

Los Grupos

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.

And Performance

A bioenergetical analysis of manoeuvrability and agility performance for wheelchair players is inexistent. It was aimed at comparing the physiological responses and performance obtained from the octagon multistage field test (MFT) and the modified condition in “8 form” (MFT-8). Sixteen trained wheelchair basketball players performed both tests in randomized condition. The levels performed (end-test score), peak values of oxygen uptake(VO2peak), minute ventilation(VEpeak), heart rate(HRpeak), peak and relative blood lactate (Δ[Lact−] = peak – rest values), and the perceived rating exertion (RPE) were measured. MFT-8 induced higherVO2peakandVEpeakvalues compared to MFT (VO2peak: 2.5 ± 0.6 versus 2.3 ± 0.6 L·min−1andVEpeak: 96.3 ± 29.1 versus 86.6 ± 23.4 L·min−1;P<0.05) with no difference in other parameters. Significant relations betweenVEpeakand end-test score were correlated for both field tests(P<0.05). At exhaustion, MFT attained incompletelyVO2peakandVEpeak. Among experienced wheelchair players, MFT-8 had no effect on test performance but generates higher physiological responses than MFT. It could be explained by demands of wheelchair skills occurring in 8 form during the modified condition.
