“…In Figure 4, the percentage of active time compared to total training time does not differ in the three periods, which is consistent with the values recommended by experts for female tennis players [15]. In the competitions, the values of the performance indicators from the period decreased, and in the competition period, they correspond to the values measured in many studies [30][31][32][33]. In Figure 4, the percentage of active time compared to total training time does not differ in the three periods, which is consistent with the values recommended by experts for female tennis players [15].…”

The purpose of this article is to present the use of a previously validated wearable sensor device, Armbeep, in a real-life application, to enhance a tennis player’s training by monitoring and analysis of the time, physiological, movement, and tennis-specific workload and recovery indicators, based on fused sensor data acquired by the wearable sensor—a miniature wearable sensor device, designed to be worn on a wrist, that can detect and record movement and biometric information, where the basic signal processing is performed directly on the device, while the more complex signal analysis is performed in the cloud. The inertial measurements and pulse-rate detection of the wearable device were validated previously, showing acceptability for monitoring workload and recovery during tennis practice and matches. This study is one of the first attempts to monitor the daily workload and recovery of tennis players under real conditions. Based on these data, we can instruct the coach and the player to adjust the daily workload. This optimizes the level of an athlete’s training load, increases the effectiveness of training, enables an individual approach, and reduces the possibility of overuse or injuries. This study is a practical example of the use of modern technology in the return of injured athletes to normal training and competition. This information will help tennis coaches and players to objectify their workloads during training and competitions, as this is usually only an intuitive assessment.

“…The mean acceleration for each 4 min stage of groundstroke hitting for each subject at each anatomical site were used for subsequent analysis. The rationale for taking the mean acceleration over the 4 min period was to align the timescale of the acceleration data with that of the oxygen uptake kinetics which has been shown to be appropriate under similar experimental conditions [8] including activities with measurements of distal limb acceleration [20].…”

Tennis ball machine tests permit the concurrent measurement of physiological function and groundstroke performance in a sport specific manner. The purpose of this study was to understand further the demands of groundstroke performance during a test with progressively increasing ball frequency, by determining the running speed between strokes, upper and lower limb acceleration and pulmonary gas exchange throughout. Sixteen tennis players (n = 8, male; n = 8, female; all right handed) completed three 4 min stages of hitting against a ball feed frequency of 15, 20, 25 ball.min(-1) interspersed by 8 min of rest. Stepwise multiple regression analysis identified a predictive model of VO2 containing the variables of left arm acceleration and right ankle acceleration but not running speed (p < 0.0001; adjusted r2 = 0.93; left wrist acceleration Beta = 1.04; right ankle acceleration Beta = - 0.12; S. E. E. = 2.61 ml.kg(-1).min(-1)). Regression analysis found that the strongest predictors of stroke performance (ball speed [m.s(-1)] x stroke accuracy [%]) were right wrist acceleration and stroke economy (p < 0.0001; adjusted r2 = 0.28; right wrist acceleration Beta = - 0.59; movement economy Beta = - 0.28). The findings of this study highlight the contribution of limb acceleration and not running speed to the oxygen cost of tennis groundstroke performance.

“…20 Players perform an average of 2.5 to 3 shots per rally, depending on playing style, ball type, surface, gender, and tactical strategy. 15,18,[21][22][23] Most matches consist of work and rest periods of 5-10 s and 10-20 s, respectively, interspersed with rest periods between rallies and switching pauses. 22,24 In tennis, there are no studies that analyze workload during practice or compare athletes' workload during preparation periods and tournaments.…”

The aim of this single case study was to monitor the external workload of a professional female tennis player between 314 training sessions and 115 matches. A wearable device was used during two fully consecutive tennis seasons (24 months). External workload was determined using time indicators (total and active session times), shots indicators (shots per week, session, hour, rally and minute) and frequency distribution of rallies. This case study showed that the workload during practice sessions was higher compared to matches in terms of active time, percentage of active time, shots per hour and rally, and frequency distribution of rallies with more than nine shots. The number of shots executed per minute was lower in the practice sessions than in the match. It is concluded that the recommended number of shots per hour in a 90-min practice session is for the player to perform 400 to 800 shots. The recommended average number of rallies in practice sessions is 144 and 70% of the rallies should consist of four shots. The pace of rallies in open match situations in the practice sessions should reach the level of official matches. These conclusions could be useful guidelines for determining the workload of female tennis players participating in entry-level professional tournaments.
