Concurrent training enhances athletes ' cardiovascular and cardiorespiratory measures . We evaluated the effects of concurrent strength and aerobic endurance training on cardiovascular and cardiorespiratory adaptations in college athletes and compared two concurrent exercise ( CE ) protocols . Separate experiments were performed on 30 women ( mean age 19.6 years ) and 20 men ( 20.4 years ) . In both experiments , subjects were divided into two groups ( serial CE and integrated CE ) matched for initial physical condition and trained in a vigorous 3-day per week CE program of 9 ( men ) to 11 ( women ) weeks . The two CE training protocols were equilibrated for exercise mode , intensity , and volume , differing only in the timing and sequence of exercises . During training , serial CE discernibly ( p < 0.05 ) increased cardiovascular adaptation in women , indicated by reduction ( -5.7 % ) in active heart rate ( HR ) ( HR/aerobic exercise intensity ) , whereas integrated CE discernibly reduced active HR in women ( -10.7 % ) and men ( -9.1 % ) . Before and after comparisons in the larger sample of women showed that serial CE discernibly reduced systolic and diastolic blood pressure ( BP ) ( -8.7 % and -14.0 % , respectively ) , increased estimated [ latin capital V with dot above ] o2max ( 18.9 % ) , and produced a trend ( 0.10 > p > 0.05 ) toward reduced resting HR ( -4.9 % ) . Integrated CE in women discernibly reduced systolic and diastolic BP ( -13.2 % and -12.6 % , respectively ) , increased estimated [ latin capital V with dot above ] o2max ( 22.9 % ) , and produced a trend toward reduced resting HR ( -2.4 % ) . Integrated CE produced discernibly larger gains than serial CE or a trend for four of six training adaptations . Effect sizes were generally large ( 60.0 % of discernible differences ) . We conclude that , for cardiovascular and cardiorespiratory adaptations in athletes , strength and endurance training are compatible and that exercise timing and sequence significantly influence training adaptations , complimenting our previous similar conclusions for strength , muscle endurance , body composition , and flexibility .
