Abstract(s)
A ordem dos exercícios desempenha um papel significativo nas respostas ao treino da
força e consequentes adaptações, porém, existem ainda alguns aspetos por esclarecer em
torno deste tópico, uma vez que recentes investigações têm vindo a contrariar literatura
científica previamente publicada. O presente estudo teve como objetivo analisar a
influência da ordem dos exercícios de supino e agachamento enquanto primeiro e
segundo exercício da sessão de treino na velocidade de execução do movimento. Dez
indivíduos treinados (20.9±0.7 anos de idade) foram submetidos, de modo
randomizado, a dois protocolos de treino da força, cada um consistindo na execução de
três séries de seis repetições com 80% da carga externa correspondente a uma repetição
máxima, com diferentes sequências de exercício: supino seguido de agachamento (S+A)
e agachamento seguido de supino (A+S). Um medidor linear de velocidade foi acoplado
à barra da máquina Smith, com a qual foram os exercícios foram executados, de modo a
registar valores referentes à velocidade média propulsiva (VMP), pico de velocidade (PV)
e ao tempo até ao pico de velocidade (TPV). Complementarmente, foram também
medidos o lactato sanguíneo e a frequência cardíaca. Relativamente ao exercício de
supino, diferenças significativas foram encontradas ao nível da VMP na primeira (S+A:
0.50 ± 0.07m·s-1 vs. A+S: 0.42 ± 0.08m·s-1; p= 0.03, g= 0.72) e segunda série (0.50 ±
0.06m·s-1 vs. 0.42 ± 0.07m·s-1; p= 0.03, g= 0.73), assim como no PV, na segunda série
(0.74 ± 0.09m·s-1 vs. 0.63 ± 0.09m·s-1; p= 0.02, g= 0.86). Quanto ao exercício de
supino, embora se tenham registado velocidades de execução do movimento superiores
no protocolo A+S, não se verificaram diferenças significativas entre protocolos. Estes
resultados demonstraram que a execução do exercício de agachamento teve um
consequente decréscimo na velocidade de execução do exercício de supino.
Contrariamente, a velocidade de execução do exercício de agachamento não foi
significativamente afetada pela execução prévia do supino.
Exercise order plays a significant role on strength training responses and subsequent adaptations, although some aspects surrounding this topic remain unclear, as recent research findings seem to contradict previous recommendations. The present study aimed to analyse the influence of exercise order using the bench press and squat as the first or second exercise of the session on velocity performance. Ten male-trained individuals (20.9±0.7 years) randomly performed two protocols of three sets of six repetitions at 80% of one-repetition maximum with different exercise sequence: bench press followed by squat (BP+S) and squat followed by bench press (S+BP). A linear velocity transducer attached to the Smith machine barbell measured mean propulsive velocity (MPV), peak velocity (PV), and time to peak velocity (TPV). Additionally, blood lactate and heart rate were measured. Regarding bench press, differences were found in MPV in the first (BP+S: 0.50 ± 0.07m·s-1 vs. S+BP: 0.42 ± 0.08m·s-1; p= 0.03, g= 0.72) and second sets (0.50 ± 0.06m·s-1 vs. 0.42 ± 0.07m·s-1; p= 0.03, g= 0.73), as well as in PV in the second set (0.74 ± 0.09m·s-1 vs. 0.63 ± 0.09m·s-1; p= 0.02, g= 0.86). Regarding the squat, although the S+BP tended to show higher velocities, no significant differences were found between protocols. These results showed that squatting first decreased subsequent bench press velocity performance. On the other hand, squat velocity performance was not impaired when preceded by the bench press.
