Book excerpt: ABSTRACT: The purpose of the study was to determine if there was a relationship between lower-body power and swimming start performance analyzed through a correlation between the horizontal and vertical direction jump ability with the swimming start performance. Data were collected from 30 healthy adolescent swimming athletes (14.16 ± 1.47 years, 163.24 ± 7.54 cm, 50.09 ± 8.61 kg). These subjects were measured on anthropometric tests, dry-land lower-body power tests and swimming start performance tests. In the on-block phase, the results showed that lower-body power correlated with time on-block and take-off velocity. Specifically, for the vertical jump direction, CMJ and SJ were significantly correlated with time on-block (r = -.513, r2 = .263, p = .031; r = -.537, p = .025, respectively), whereas, for the horizontal jump direction, the SLJ was significantly correlated with time on-block and take-off velocity (r = -.592, r2 = .350, p = .042; r = .631, r2 = .398, p = .015, respectively). However, the lower-body power was not significantly to the reaction time or drive angle (p > .05). In the flight phase, for the horizontal jump direction, the SLJ was significantly correlated with flight distance and flight time (r = .655, r2 = .429, p = .028; r = .563, r2 = .317, p = .035, respectively), whereas no significant correlation was observed between SLJ and angle of entry. For the vertical jump direction, the CMJ and SJ were unrelated to flight distance, flight time or the angle of entry (p > .05). In the underwater-swimming phase, a significant correlation was observed between the CMJ, SJ and SLJ with time to 5 meters (r = -.597, r2 = .356, p = .018; r = .633, r2 = .400, p = .028; r = -.723, r2 = .523, p = .023, respectively). Besides, the lower-body power (CMJ, SJ and SLJ) was unrelated to time to 10 meters (p > .05).
