ELECTRICAL STIMULATION USE IN TENNIS 2

ABSTRACT.–The purpose of this preliminary study was to show the feasibility of

electrostimulation (ES) strength exercise incorporated into tennis sessions during the

preparatory season of competitive players, and its impact on anaerobic performance. Twelve tennis players (five males, seven females) completed nine sessions of quadriceps ES

(duration: 16 min; frequency: 85 Hz; on-off ratio: 5.25-25 s) over three weeks. ES sessions were integrated into tennis training sessions. Subjects were baseline tested and retested one (week 4), two (week 5), three (week 6) and four weeks (week 7) after the ES training program for maximal quadriceps strength, vertical jump height and shuttle sprint time. Participants were able to increase progressively ES current amplitude and evoked force throughout the nine training sessions, with an optimal treatment compliance of 100%. Maximal quadriceps strength significantly increased during the entire duration of the experiment (p < 0.001). Countermovement jump height at week 5 (+5.3%) and week 6 (+6.4%) was significantly higher than baseline (p < 0.05). In addition, 2×10 m sprint time at week 6 was significantly shorter (-3.3%; p = 0.004) compared to pre-training. The 3-week ES strength training program

was successfully incorporated into preseason tennis training with a linear progression in all training parameters. Throughout the study period, a ‘delayed’ enhancement of anaerobic power and stretch-shortening cycle performance was observed. Progressive ES strength training may be safely included in the early tennis season, and can lead to improvement in anaerobic performance of male and female players.
