The present study aimed at examining the physiological characteristics and metabolic demands of badminton single match play. Twelve internationally ranked badminton players (eight women and four men) performed an incremental treadmill test [VO 2peak = 50.3 § 4.1 ml min ¡1 kg ¡1 (women) and 61.8 § 5.9 ml min ¡1 kg ¡1 (men), respectively]. On a separate day, they played a simulated badminton match of two 15 min with simultaneous gas exchange (breath-by-breath) and heart rate measurements. Additionally, blood lactate concentrations were determined before, after 15 min and at the end of the match. Furthermore, the duration of rallies and rests in between, the score as well as the number of shots per rally were recorded. A total of 630 rallies was analysed. Mean rally and rest duration were 5.5 § 4.4 s and 11.4 § 6.0 s, respectively, with an average 5.1 § 3.9 shots played per rally. Mean oxygen uptake (VO 2), heart rate (HR), and blood lactate concentrations during badminton matches were 39.6 § 5.7 ml min ¡1 kg ¡1 (73.3% VO 2peak), 169 § 9 min ¡1 (89.0% HR peak) and 1.9 § 0.7 mmol l ¡1 , respectively. For a single subject 95% conWdence intervals for VO 2 and HR during match play were on average 45.7-100.9% VO 2peak and 78.3-99.8% HR peak. High average intensity of badminton match play and considerable variability of several physiological variables demonstrate the importance of anaerobic alactacid and aerobic energy production in competitive badminton. A well-developed aerobic endurance capacity seems necessary for fast recovery between rallies or intensive training workouts.
Physiological Characteristics of Indonesian Junior Badminton Players: Men's Double Category
International Journal of Human Movement and Sports Sciences, 2020
The primary aim of this study is to assess the VO 2max and anthropometric characteristics of men's double category; Next is to analyze match characteristics of men's double category; and finally, to compare the heart rate (HR) and blood lactate concentration calculated on-court with that obtained under laboratory conditions during an incremental test. 12 junior badminton players from Jaya Raya Badminton Club were enrolled as the subjects for this study. All participants were partnered up in 6 pairs (pair 1 to pair 6). During the first session (laboratory condition), VO 2max was measured by using a velocity dependent ramp test (INCS) based on incremental protocols. During the second session (on-court condition), the participants played a simulated match on court. A total of 350 rallies were analyzed. Statistical analyses revealed that double junior men's players hit the shuttlecock more often using drive shots techniques (466 shots). The ANOVA revealed significant differences regarding f B between pair 3 vs pair 6 (p=0.004), pair 4 vs pair 6 (p=0.030), and pair 5 vs pair 6 (p=0.023). For the lactate measures, ANOVA revealed significant main effects of time (p=0.001) and group (p=0.001). Furthermore, the significance of HR average among laboratory and on-court conditions was established with the help of an independent t-test. The study demonstrated that the physiological characteristics of Indonesian men's double category are intermittent activities of high and low intensities, interspersed by short recovery periods. It was also discovered that the adrenergic strategy results in enhanced HR and lactate levels in the laboratory than on-court conditions.

Aim: To develop a badminton specific test to determine on court aerobic and anaerobic performance. Method: The test was evaluated by using a lactate steady state test. Seventeen male competitive badminton players (mean (SD) age 26 (8) years, weight 74 (10) kg, height 179 (7) cm) performed an incremental field test on the badminton court to assess the heart rate turn point (HRTP) and the individual physical working capacity (PWC i) at 90% of measured maximal heart rate (HR max). All subjects performed a 20 minute steady state test at a workload just below the PWC i. Results: Significant correlations (p<0.05) for Pearson's product moment coefficient were found between the two methods for HR (r = 0.78) and velocity (r = 0.93). The HR at the PWC i (176 (5.5) beats/min) was significantly lower than the HRTP (179 (5.5) beats/min), but no significant difference was found for velocity (1.44 (0.3) m/s, 1.38 (0.4) m/s). The constant exercise test showed steady state conditions for both HR (175 (9) beats/min) and blood lactate concentration (3.1 (1.2) mmol/l). Conclusion: The data indicate that a valid determination of specific aerobic and anaerobic exercise performance for the sport of badminton is possible without HRTP determination.

The aim of the study was to determine the cardiorespiratory and metabolic characteristics during intense and moderate table tennis (TT) training, as well as during actual match play conditions. Blood lactate concentration (Lac), heart rate (HR, beats per minute [bpm]), oxygen uptake (VO2), and energy expenditure (EE) in 7 male participants of the German junior national team (age: 14 ± 1 y, weight: 60.5 ± 5.6 kg height; 165 ± 8 cm) were examined during six training sessions (TS) and during an international match. The VO2 was measured continuously with portable gas analyzers. Lac was assessed every 1 to 3 min during short breaks. Mean (peak) values for Lac, HR, VO2, and EE during the TS were 1.2 ± 0.7 (4.5) mmol·L-1, 135 ± 18 (184) bpm, 23.5 ± 7.3 (43.0) mL·kg-1· min-1, and 6.8 ± 2.0 (11.2) METs, respectively. During match play, mean (peak) values were 1.1 ± 0.2 (1.6) mmol·L-1, 126 ± 22 (189) bpm, 25.6 ± 10.1 (45.9) mL·kg-1·min-1, and 4.8 ± 1.4 (9.6) METs, respectively. For the first ...
E I N E M A N N Sport specific fitness testing of elite badminton players
There is a scarcity of descriptive data on the performance capacity of elite badminton players, whose fitness requirements are quite specific. The purpose of this paper is to investigate the physiological response of elite badminton players in a sport-specific fitness test. Twelve Hong Kong national badminton team players performed a field test on a badminton court. Six light bulbs were connected to a programming device causing individual bulbs to light up in a given sequence. The players were instructed to react to the flashes by running towards them, and striking shuttles mounted in the vicinity of the bulbs. Exercise intensity was controlled by altering the interval between successive lightings. A low correlation (r = 0.65) was found between the results of the field test and the rank-order list of subjects, based on an objective on-field physiological assessment and subjective ranking. This may be explained by the requirements of other factors besides physical fitness which contribute to success in elite level badminton competition. These factors may include, for example, technical skill, mental power, and aesthetic judgements on the court. Maximum mean(s.d.) heart rate data (187(8) beats * min-) and blood lactate values (10.4(2.9) mmol *11) in this study showed that players were under maximal load during the field test. From the testing data, it seems reasonable to speculate that the intensity of level 3 (20 light pulses min-; 3.0 s *ulse-l) and level 4 (22 light pulses * minu ; 2.7 spulse ) simulates the requirement of actual game energy expenditure of the Hong Kong badminton players exercising at close to their anaerobic threshold. The results also show that an estimate of fitness can be derived from measurements involving exercise closely resembling that which is specific for the sports activity in question. Improved training advice and guidance may result from such studies. (Br J Sports Med 1995; 29: 153-157)

To investigate short-term training and recovery-related effects on heart rate during a standardized submaximal running test. Methods Ten elite badminton players (7 females and 3 males) were monitored during a 12-week training period in preparation for the World Championships. Exercise heart rate (HRex) and perceived exertion were measured in response to a 5-min submaximal shuttle-run test during the morning session warm-up. This test was repeatedly performed on Mondays after 1-2 days of pronounced recovery ('recovered' state; reference condition) and on Fridays following 4 consecutive days of training ('strained' state). In addition, the serum concentration of creatine kinase and urea, perceived recovery-stress states, and jump performance were assessed before warm-up. Results Creatine kinase increased in the strained compared to the recovered state and the perceived recovery-stress ratings decreased and increased, respectively (range of average effects sizes: |d| = 0.93-2.90). The overall HRex was 173 bpm and the observed withinplayer variability (i.e., standard deviation as a coefficient of variation [CV]) was 1.3% (90% confidence interval: 1.2% to 1.5%). A linear reduction of-1.4% (-3.0% to 0.3%) was observed in HRex over the 12-week observational period. HRex was-1.5% lower (-2.2% to
Heart rate and blood lactate responses during the volleyball match
Scientific Reports
This study aimed to examine the heart rate and blood lactate responses of female volleyball players during the match according to the player positions. A total of 24 senior female volleyball players (middle blocker (n = 6), setter (n = 6), spiker (n = 6), and libero (n = 6)) were monitored for heart rate and blood lactate before, during and after a volleyball match. The mean heart rate and blood lactate level of volleyball players were determined 117.2 ± 13.9 bpm, 2.7 ± 1.2 mmol/L during the match. Heart rate was statistically different between all playing positions except middle blockers vs. spikers (p < 0.05). The blood lactate levels between the groups were not statistically different. The setters have the lowest heart rate and the libero players have the highest during the match. All subjects have a heart rate 50–60% and below 50% of their heart rate maximum during more than half of the match duration. These current results can be used by coaches to determine a specific train...
