Individual Sports

Tennis is one of the most popular individual sports all over the world. Strength and trained muscles are required for a player in order to achieve a good backhand, forehand, volley or flat stroke. Especially while playing tennis are many kinds of muscles involved, including the lower body muscles, trunk muscles and upper body muscles. The purpose of this review is to present the activated muscles in the basic tennis movements of forehand and backhand and to improve the knowledge about their role in order to help tennis players and coaches to enhance their tennis performance and to reduce risk of injury. To support the present review, data were gathered from library and network databases using keywords such as tennis, muscles, forehand, and backhand for publications between 2015 and 2019. Overall, thirty-five references were detected and used. The literature showed that forehand and backhand drives are strokes that involve muscles not only of the upper limbs but also a series of more complex movements that start with the feet and end with the swinging of the tennis racket. The insight for the action of the muscles in tennis should be utilized in tennis players so as to better understand the muscular function which takes part in specific tennis movements and has a greater performance. In addition, this knowledge is considered strongly beneficial for the coaches and the favourable building of the training process.

Absolute Effect

Delayed onset muscle soreness (DOMS) is a very common musculoskeletal problem in athletes involved in extreme competitions. The aim of this study is to compare the effect of diathermy, sham diathermy and massage on the knee proprioception of athletes treated for DOMS. Forty athletes were enrolled after the second day of a demanding ski mountaineering race. They were randomly assigned to four groups: no treatment [Formula: see text], massage [Formula: see text], diathermy [Formula: see text], and sham diathermy [Formula: see text]. The knee reposition error was measured after the treatments in order to assess knee proprioception. Significant differences between the diathermy and sham diathermy groups were found ([Formula: see text]) with an absolute effect size of [Formula: see text]. No other significant differences were found among groups. This means that diathermy has a negative impact on joint proprioception and can be explained by the spindle desensitization consequent to deeper tissue heating. This information can be important in the DOMS management of athletes, since an altered proprioception may interfere with the athlete’s performance and can increase the risk of injury.

Stress Levels

The present study aimed at (i) investigating weekly variations in wellness ratings relative to Hooper indicators (HI): fatigue (wFatigue), stress levels (wStress), delayed onset muscle soreness (wDOMS), sleep quality/disorders (wSleep), and wHI across the full preparation season (PS) and (ii) comparing the aforementioned variables between three periods: early-PS, week (W) W1 to W11; mid-PS, W12 to W22; end-PS, W23 to W32. Ten elite young wrestlers were involved in this study (age, 16 ± 0.7 years; height, 163 ± 4.8 cm; body mass, 57.7 ± 9.0 kg; VO2max, 48.7 ± 1.4 mL/kg−1/min−1). Wellness status was monitored daily using the HI questionnaire. The main results were found in W26 (24.2 ± 3.9 arbitrary units (AU)) and W14 (17.9 ± 7 AU) with the highest and lowest wDOMS, respectively. Decreases in wDOMS were reported during the PS. For wFatigue, the highest and lowest values belong to W19 (24.3 ± 3.3 AU) and W32 (16.7 ± 3.9 AU), respectively. In the case of wFatigue, the level increased within the PS. The highest wHI was observed in W19 (88.5 ± 7.7 AU) and the lowest in W32 (72.3 ± 6.1 AU). There were no significant changes between early-PS compared to mid- and end-PS, while significant changes were found for mid-PS in comparison to the end-PS. Changes in wDOMS, wStress, and wFatigue were in line with the changes in Hooper’s scoring. All PS daily monitoring results can provide a great standpoint from which coaches can determine wellness status throughout the season in elite youth level athletes. This information can be used to avoid the risk of injury, overtraining, and non-functional overreaching.

Background: Balancing training load helps prevent injury and maximize performance, but coaches do not often know the load or intensity of drills when making selections for practice. Objective: This study aimed to classify the drills of a women’s collegiate lacrosse team into low, moderate, and high intensity categories. Methods: Twenty-five participants wore global positioning system (GPS) devices and heart rate (HR) monitors daily during team practice and scrimmage matches. The data collected was trimmed to reflect only the time the players practiced and then organized by drill. Mean HR, distance rate, and training impulse (TRIMP) scores were used to classify drills into tertiles: low, moderate, and high intensity. Results: A total of 56 unique drills were analyzed over 33 training days, with 24 drills considered moderate intensity, 17 drills were high intensity, and 15 drills were low intensity. By position, 17 drills were low intensity for the midfielders, followed by 16 for the attacker, and 12 for the defenders and goalies. The defenders had the highest number of moderate intensity drills with 27, followed by the attackers with 24, midfielders with 21, and goalies with 17. Lastly, midfielders and goalies had the highest number of high intensity drills with 18, followed by attackers with 17, and defenders with 16. Conclusions: These results will help the coaching and training staff manage workloads and potentially reduce risk of injury and overtraining by giving insight into the demands of each drill they require of their athletes.
