The aim of this study was to examine the effects ofshort-term (six weeks) preseason strength and jumping exercises distribution programon amateur adult soccer player’s indicators of physical fitness. Twenty maleathletes (age 20.1±1.6years) were randomly divided into two groups that completed a volume-equatedtraining program differingonly in exercises distribution:a group that completed three weeks of strength followed by three weeksof plyometric training (TT;n=10) and a group that completed six weeks of combined strength and plyometric drills (S+P; n=10). Athletes completed a triplehop test with the dominant (HOPd) and non-dominant leg (HOPnd), a 15 meterssprint, a change of direction speed(CODS) test (i.e. T test), anda 6×30 meters repeated sprint with change of direction for the best (RSCODb) and mean velocity (RSCODm),and the percentage of decrement (%Dec) in sprint time. Moreover, athletesperformed a squat test formaximal power. Both strength and jumping training programs were performed two timesper week, equated for exercises, frequency, volume, and intensity per session. TheTT group completed the strength training volume during the first three weeks,and the plyometric training volume in the last three weeks, while the S+P combined strength and plyometric training during thesix weeks. A 2 (group) × 2 (time: pre, post) ANOVA with repeated measures was usedfor statistical analysis. Analysesrevealed significant improvements for the TT and S+P (HOPd: ES=0.91, 10.28 and16.69%, respectively; HOPnd: ES=0.86, 11.49 and 14.71%, respectively; RSCODb:ES=0.84, 9.23 and 8.34%, respectively; RSCODm: ES=0.89, 8.56 and7.51%, respectively). In thepost-test there were no significant differences between the groups in anyvariable analyzed. In conclusion, both training approaches were equally effective atimproving jumping and repeated sprinting ability. However, only after the S+Ptraining approach a significant improvement in CODS was observed, with more substantial changes in maximal sprintingspeed.
