Effects of two different tapering protocols on fitness and physical match performance in elite junior soccer players

The purpose of the present study was to determine the effects of two different tapering protocols on fitness and physical match performance in elite junior soccer players. One-hundred and fiftyeight elite junior soccer players (mean age: 17.1±0.79 yrs ; mean height: 177.9±6.64 cm ; mean weight: 71.3±7.96 kg ; mean body-mass index: 22.5±1.66 kg/m2 ) were randomly assigned to two groups: an exponential (n=79) and a linear tapering (n=79) group. Training sessions were conducted 3 times per week for 8 weeks. After 4 weeks of training and 4 weeks of tapering, participants were assessed in terms of body composition, physical fitness and distance covered distance covered within a match. Both groups showed similar changes for body composition. The exponential group showed better improvement than the linear group in the 5 and 30 m sprints, squat jump with arm swing and VO2max (p<0.05). The exponential tapering group had larger changes (p<0.05) than the linear group in medium running (8-13 km/h) (6% ; ES=0.26 compared to 5.5% ; ES=0.22) and sprinting (>18 km/h) (26% ; ES=0.72 compared to 21.7% ; ES=0.60). The results show that exponential tapering produced better effects on speed, power and endurance abilities than the linear protocol. Our results confirmed the reports of others that suggest that volume is the optimal variable to manipulate while maintaining both the intensity and the frequency of sessions
