"Effects of Congested Fixture on Men’s Volleyball Load Demands: Interactions with Sets Played"
O docente do Departamento de Desporto do nosso Instituto, o Prof. Sérgio Matos, em parceria com outros investigadores nacionais e internacionais, lançou recentemente um novo artigo científico. Com o título "Effects of Congested Fixture on Men’s Volleyball Load Demands: Interactions with Sets Played”, o artigo científico publicado no Journal of Functional Morphology and Kinesiology, tem o objetivo comparar a carga externa, a carga interna e a eficácia técnica entre o primeiro e o segundo jogo em jornada dupla usando o número de sets como um fator moderador.
The purpose of this study was to compare the external load, internal load, and technical efficacy between the first and the second matches (M1 and M2) occurring in congested fixtures (two matches in two days) using the number of sets as a moderating factor. An observational analytic research design was adopted. Data from official volleyball matches were collected during the first competitive period of the championship, comprising 14 competitive games within 10 weeks. Ten male elite volleyball athletes (age: 21.7 ± 4.19 years of age; experience: 6.2 ± 3.8 years; body mass: 85.7 ± 8.69 kg; height: 192.4 ± 6.25 cm; BMI: 23.1 ± 1.40 kg/m2) participated in this study. Players were monitored for external load (number of jumps and height of jumps) and internal load (using the rate of perceived exertion—RPE). Additionally, notational analysis collected information about attack efficacy and receptions made during matches. The mixed ANOVA revealed no significant interaction between time (M1 vs. M2) and number of sets for number of jumps per minute (p = 0.235; η2p = 0.114), mean jump height (p = 0.076; η2p = 0.193), RPE (p = 0.261; η2p = 0.106), attack efficacy (p = 0.346; η2p = 0.085), Positive reception (p = 0.980; η2p = 0.002) and Perfect reception (p = 0.762; η2p = 0.022). In conclusion, congested fixtures do not seem to affect the performance of volleyball players negatively.
