Chainok, Phornpot; de Jesus, Karla; Mourão, Luis; Fonseca, Pedro Filipe Pereira; Zacca, Rodrigo; Fernandes, Ricardo J.; Vilas-Boas, João PauloThis study aimed to identify the biomechanical features of backstroke to breaststroke transition techniques (open, somersault, bucket, and crossover) in age-group swimmers. Eighteen preadolescent swimmers (12.2 ± 0.4 years old and 3–4 Tanner stages) underwent 4 weeks of systematic contextual interference training, comprising 16 sessions (40 min·session−1). Soon after, experimental testing was conducted where sw...
The effect of different foot and hand set-up positions on backstroke start perf...
Jesus, Karla de; Abraldes, José Arturo; Mourão, Luis; Santos, Márcio Borgonovo; Medeiros, Alexandre Igor Araripe; Gonçalves, Pedro; Chainok, PhornpotFoot and hand set-up position effects were analysed on backstroke start performance. Ten swimmers randomly completed 27 starts grouped in trials (n = 3) of each variation, changing foot (totally immersed, partially and totally emerged) and hand (lowest, highest horizontal and vertical) positioning. Fifteen cameras recorded kinematics, and four force plates collected hands and feet kinetics. Standardised mean di...
