abstract = {To investigate the effects of a badminton competition with 2 matches in a day on hip strength
and range of motion (ROM) and exercise-induced muscle damage in elite junior badminton players. Twenty
players (age: 17±0.8 years; body mass: 62.9±6.5 kg, height: 173.8±8.9 cm) participated in this study. Passive
hip internal (IR) and external rotation (ER), abduction (ABD) and adduction (ADD) hip ROM, isometric hip ADD
and ABD muscle strength, countermovement vertical jump (CMJ) height and blood creatine kinase concentration (CK)
were measured before and after a badminton competition during an international tournament. Blood samples
were collected 24 h after the end of the last match. Compared to baseline values, hip IR and ER ROM were
significantly decreased at post-competition in the dominant (IR=-9.0%; p=0.007 and ER=-15.2%; p=0.002)
and non-dominant limbs (IR=-9.08%; p=0.004 and ER=-19.4%; p<0.001). In contrast, hip ADD (13.5%;
p<0.001) and ABD (14.6%; p<0.001) strength increased significantly after the competition in the dominant
limb and ABD strength increased significantly in the non-dominant limb (9.2%; p=0.001). From baseline values,
CK increased after the competition (430.1%) and values remained elevated over baseline values 24 h later
(160.4%). Although hip muscle strength increased, a badminton competition with two consecutive matches
reduced hip ROM and increased blood CK concentration. This study suggests the necessity of investigating
recovery strategies after a badminton competition to return hip ROM to basal values before the next day of
the competition.},
