Abstract
Aim: To evaluate the intensity of training and official badminton matches (international championship) in junior elite players. Methods: Twelve elite players from the Brazilian junior national team (6 male and 6 female) were monitored during 19 training sessions and 50 official men's and women's single and double matches in the XXVII Pan-American Junior Games. Subjects underwent an incremental running step test to determine maximal oxygen uptake (VO2max), and an individual relationship between heart rate (HR) and VO2max was established to estimate exercise intensity and oxygen uptake at official matches (OMs) and training sessions. HR was monitored during multi-shuttlecock (MS), technical-tactical (TT), and physical (PS) training methods, as well as during simulated matches (SMs) and OMs. Variables such as %HRmax, HR zones, %VO2max, and energy expenditure were also calculated. Results: OM was the most intense activity monitored for male and female athletes, followed by SM according to %HRmax (86.8 ± 4.1% and 84.4 ± 5.0% for female and male, respectively, in OM vs. 74.6 ± 2.3% and 75.0 ± 5.0% for female and male, respectively, in SM). OM mean energy expenditure was 10.7 ± 0.5 kcal.min-1 for females and 14.9 ± 4.6 kcal.min−1 for males. Conclusion: MS training has less physiological demand and OM presented higher intensity. SM, on the other hand, had the closest physiological demand to an OM.
Highlights
Badminton has greatly gained in popularity since its inclusion in the 1992 Olympic Games in Barcelona, and, according to the World Badminton Federation, around 200 million people play badminton worldwide[1]
Considering that the analysis of training and official matches (OMs) intensities is key to unravel the demands of a sport, further studies are recommended to better elucidate these features in badminton junior elite players
OM had higher %HRmax than the training methods analyzed (p < 0.009, η2 = 0.8), PS was superior to MS (p = 0.005, η2 = 0.7), and simulated matches (SMs) had higher values than MS and TT (p < 0.048, η2 = 0.8)
Summary
Badminton has greatly gained in popularity since its inclusion in the 1992 Olympic Games in Barcelona, and, according to the World Badminton Federation, around 200 million people play badminton worldwide[1]. Run, jump, and attack with the racket at high speed and intensity[2,3]. As it is characterized by actions of short duration, high intensity, and a short resting time at a high level of play, players must display specific technical and physical conditions[4]. The game changed over the years, increasing the metabolic demands and requiring a greater resting time
