Purpose : In rowing, the effectiveness of adding high-intensity interval training (HIIT) to moderate-intensity continuous (MICT) within weekly program on physiological adaptations and performance is still unclear. This study compared effects HIIT plus MICT (MIXED) versus alone physiological/metabolic responses in adolescents. Methods Twelve highly trained adolescent rowers (age: 15.7 [0.5] y) were divided into 2 groups: MIXED MICT. Before after a 7-week intervention period, underwent an incremental step test determine peak oxygen uptake (VO peak), power at VO (WVO corresponding lactate concentration 4 mmol·L −1 , output threshold, second threshold 2LT ), pulse. Training load from TRIMP was also measured. The consisted 7 sessions per week including “off-water,” 3 “on-water,” resistance-training sessions. “on-water” same for both groups, while during “off-water” sessions, group performed (4 × min 85% WVO peak) (80 70% peak). Results Statistical analysis showed that group, significantly increased reduced ( P < .00001) with = .008). Both groups similarly improved peak, pulse, . Conclusions Our findings that, rowers, enhanced thus indicating as valid time-efficient addition traditional However, given adolescents examined, data should be interpreted caution, and/or growth/maturation may have contributed changes.
