Tennis Match

Background: Tennis is an intermittent sport, characterized by hundreds of repetitive explosive efforts, including accelerations, and jumps. A single match can last up to 5 hours and players are called to play several matches often separated by less than 48h of recovery. Objective: The study aimed to investigate the effects of a standardized tennis match on perceived fatigue and jump and sprint performances on a group of recreational tennis players and to observe if such variables were affected by residual effects of fatigue 24 hours after the match. Methods: Twelve recreational tennis players performed a 120 min match. Before, immediately after and 24h after the match, players completed a set of three countermovement jumps, three 10m sprints, and reported their perception of general fatigue. Results: Significant differences between the three conditions have been found for the perceived fatigue: indeed fatigue was higher both in the immediate post (F(1,10)= 54.422, η2 = 0.845, p<0.001) and 24h post-match (F(1,10)= 10.947, η2 = 0.523, p=0.08), with respect to the pre-match condition. No significant differences were detected in the other variables. Conclusion: During a tournament, the performance of tennis players may be weakened and the recovery prejudiced. To identify fluctuations of and factors linked to fatigue may help tennis practitioners to apply adequate recovery strategies with athletes, limiting performance decrements within a tournament, and indirectly preventing injuries.

Purpose:To determine how consecutive days of prolonged tennis match play affect performance, physiological, and perceptual responses.Methods:Seven well-trained male tennis players completed 4-h tennis matches on 4 consecutive days. Pre- and postmatch measures involved tennis-specific (serve speed and accuracy), physical (20-m sprint, countermovement jump [CMJ], shoulder-rotation maximal voluntary contraction, isometric midthigh pull), perceptual (Training Distress Scale, soreness), and physiological (creatine kinase [CK]) responses. Activity profile was assessed by heart rate, 3D load (accumulated accelerations measured by triaxial accelerometers), and rating of perceived exertion (RPE). Statistical analysis compared within- and between-days values. Changes (± 90% confidence interval [CI]) ≥75% likely to exceed the smallest important effect size (0.2) were considered practically important.Results:3D load reduced on days 2 to 4 (mean effect size ± 90% CI –1.46 ± 0.40) and effective playing time reduced on days 3 to 4 (–0.37 ± 0.51) compared with day 1. RPE did not differ and total points played only declined on day 3 (–0.38 ± 1.02). Postmatch 20-m sprint (0.79 ± 0.77) and prematch CMJ (–0.43 ± 0.27) performance declined on days 2 to 4 compared with prematch day 1. Although serve velocity was maintained, compromised postmatch serve accuracy was evident compared with prematch day 1 (0.52 ± 0.58). CK increased each day, as did ratings of muscle soreness and fatigue.Conclusions:Players reduced external physical loads, through declines in movement, over 4 consecutive days of prolonged competitive tennis. This may be affected by tactical changes and pacing strategies. Alongside this, impairments in sprinting and jumping ability, perceptual and biochemical markers of muscle damage, and reduced mood states may be a function of neuromuscular and perceptual fatigue.

The Effects of Rhythm Training on Tennis PerformanceRhythm training is an integral part of sports. The purposes of the study were to analyze the effects of rhythm training on tennis performance and rhytmic competence of tennis players, to compare the improvement levels of tennis specific and general rhythm training and to examine the effects of shorter and longer tempos on rhythmic competence. Thirty university students whose mean score of International Tennis Number (ITN) was 7.3 (±0.9) were divided randomly into three sub-groups: Tennis Group, General Rhythm Training Group and Tennis-Specific Rhythm Training Group. The experimental procedure lasted 8 weeks. During this period, all groups had the same tennis training twice a week. The Tennis Group had regular tennis training sessions. In addition to regular tennis training sessions, the General Rhythm Training Group followed the general rhythm training sessions and the Tennis-Specific Rhythm Training Group had tennis-specific rhythm training. The measurement instruments were ITN, Rhythmic Competence Analysis Test and Untimed Consecutive Rally Test. The results indicated that participation in tennis-specific or general rhythm training resulted in progress in tennis playing levels, forehand consistency performance and rhythmic competence of the participants. On the other hand, attendance to the regular 8-week tennis training was enough to solely increase the tennis playing level but not sufficient to develop forehand consistency performance and rhythmic competence. Although the participants in the TRTG had better improvement scores than the ones in the GRTG, no significant difference was found between the rhythm training groups. The results also revealed that participants exhibited higher rhythmic competence scores on fast tempo compared to slow tempo.

The aim of this study was to examine the impact of a tennis player’s body language and clothing (general vs. sport-specific) on the impressions observers form of them. Forty male tennis players viewed videos of a target tennis player warming up. Each participant viewed the target player displaying one of four combinations of body language and clothing (positive body language/tennis-specific clothing; positive body language/general sportswear; negative body language/tennis-specific clothing; negative body language/general sportswear). After viewing the target player, participants rated their impressions of the model’s episodic states and dispositions and gave their perceptions of the likely outcome of a tennis match with the target player. Analyses of variance revealed that positive body language led to favorable episodic impressions and low outcome expectations. Analysis also indicated that clothing and body language had an interactive effect on dispositional judgments. The study supports the contention that nonverbal communication can influence sporting interactions.

We tested the influence of string stiffness on the occurrence of forearm muscle fatigue during a tennis match. Sixteen tennis players performed two prolonged simulated tennis matches with low-stiffness or high-stiffness string. Before and immediately after exercise, muscle fatigability was evaluated on the forearm muscles during a maximal intermittent gripping task. Groundstroke ball speeds and the profile of acceleration of the racquet frame at collision were recorded during each match. The peak-to-peak amplitude of acceleration and the resonant frequency of the frame were significantly greater with high- (5060 ± 1892 m/s2and 204 ± 29 Hz, respectively) than with low-stiffness string (4704 ± 1671 m/s2and 191 ± 16 Hz, respectively). The maximal and the averaged gripping forces developed during the gripping task were significantly reduced after the tennis match with high- (−15 ± 14%, and −22 ± 14%, respectively), but not with low-stiffness string. The decrease of ball speed during the simulated matches tended to be greater with high- than with low-stiffness string (P= .06). Hence, playing tennis with high-stiffness string promotes forearm muscle fatigue development, which could partly contribute to the groundstroke ball speed decrement during the game.

The purpose of this study was to determine visual behavior and motor responses between experienced and novice wheelchair tennis players relative to the return in tennis. Novice (n = 7) and Experienced (n = 5) wheelchair tennis players took part in the study. Two series of serves performed to the forehand and the backhand sides were examined in both groups. One series was performed in a video-based setting (two dimensional) and the other one on court (three dimensional). Experienced participants focused initially on the head/shoulders and the free-arm, while novice players focused on the expected ball toss area or followed the ball from the toss to the apex. Results suggest that the experienced players obtain useful information from racket-arm cues during the stroke phase. They also performed faster motor responses as well.

Abstract The purpose of this study was to investigate the effects of serve and return game situations on physiological responses and match characteristics in professional male tennis players during one hour-long simulated singles tennis matches. Ten internationally ranked tennis players (age 22.2 ± 2.8 years; body height 180.7 ± 4.4 cm; body mass 75.9 ± 8.9 kg) participated in this study. Their physiological responses were measured using two portable analyzers during indoor hard court matches. Ratings of perceived exertion were also determined at the end of the game. The variables describing the characteristics of the matches determined from video recordings were: (a) duration of rallies; (b) rest time; (c) work-to-rest ratio; (d) effective playing time; and (d) strokes per rally. Significant differences (p<0.05) were found between serving and returning conditions in an hour-long simulated singles tennis match in terms of oxygen uptake, a heart rate, ratings of perceived exertion, pulmonary ventilation, respiration frequency and a respiratory gas exchange ratio. In addition, both the heart rate and ratings of perceived exertion responses were moderately correlated with the duration of rallies and strokes per rally (r = 0.60 to 0.26; p<0.05). Taken together, these results indicate that the serve game situation has a significant effect on the physiological response in an hour-long simulated tennis match between professional male tennis players. These findings might be used for the physiological adaptations required for tennis-specific aerobic endurance.

The purpose of the present study was to examine the relation between the physical characteristics of male tennis players who were aged 10&ndash;12 and their service strike speeds. A total of 13 licensed male tennis players (mean age 10.1&plusmn;0.1 years, mean height 1.46&plusmn;.06 m, mean body weight 38.7&plusmn;1.8 kg, mean sporting age 4.7&plusmn;0.3 years) who played at Middle East Technical University Tennis Club participated in the study. The demographic, anthropometric, (width, length, circumference, and subcutaneous fat) and ball speed measurements of the tennis players were taken and recorded. The data were analyzed by using the &ldquo;Descriptive Statistics&rdquo; and &ldquo;Pearson Correlation&rdquo; in the Statistical Package Program. When length measurements were examined, it was determined that although there was a positive relation between ball speeds and hand length (p&lt;0.05); a negative relation was detected between the other measurements (p&gt;0.05). When the width measurements were evaluated, it was determined that although there was a positive relation between ball speeds and chest, elbow and wrist widths (p&lt;0.05); a negative relation was detected between the other measurements (p&gt;0.05). In terms of the circumferences, although a positive relation was detected between ball speeds and arm contraction, chest, chest inspiration, and chest expiration circumference (p&lt;0.05); a negative relation was detected between the other circumference measurements (p&gt;0.05). When subcutaneous fat measurements were examined, it was determined that there was a negative relation between ball speeds (p&gt;0.05). As a result, when previous studies and literature were examined, it was determined that many studies emphasized that the factors that affect the service speed of young tennis players have a positive relationship with age. It is obvious that the strength features, and depending on this, anthropometric properties improve with age. It is considered that special force and technical training drills, regardless of the age category, may affect the speed and accuracy of the service strike in tennis. Our study offers a different perspective to coaches on this subject.

Background Groin injuries are some of the most common injuries tennis players suffer. Several factors (e.g., post-match decrease in hip adductor (ADD) strength) have been proposed as possible mechanisms for increasing the incidence of this type of injury. However, the risk factors of developing groin injuries after a tennis match have not yet been delineated. Objective The aim of this study was to determine the effect of tennis match-play on isometric ADD and abductor (ABD) strength and passive hip range of motion (ROM). Methods Twenty-six male tennis players (20.30 ± 4.98 years) took part in this study. Participants completed an evaluation of strength and flexibility hip measurements before and after a simulated tennis match. Dominant and non-dominant passive hip ROM, ADD and ABD isometric strength, and the ADD/ABD strength ratio were measured before and immediately post-match. A global positioning system (GPS) and a session rating of perceived exertion (RPE) were used to assess the locomotive demands and internal match load. Results Isometric dominant ADD strength (17.8%, p ≤ 0.01) and ADD/ABD strength ratio (11.6%, p = 0.04) were lower post-match compared to the pre-match values. No between-limbs differences were observed for isometric ADD strength, ABD strength, and passive hip ROM tests. RPE showed an expected increase between pre- vs. post-match (pre- vs. post-warming-up, 3.42 ± 2.08 vs. 5.62 ± 2.29, p < 0.01). In addition, a significant relationship between ADD strength and the volume of tennis practice per week was found, stablishing that tennis players with lower volume of training per week suffered a reduction in ADD strength in their dominant limb after match-play (r = 0.420, p = 0.04). Conclusion The assessment of ADD strength and the ADD/ABD strength ratio in the dominant limb may be considered a post-match tool that can be used to identify players who require rest and additional recovery strategies before competing again.

Abstract Ceratitis capitata (Wiedemann, 1824) is the main insect pest of fruits worldwide. The objective of this study was to evaluate the toxicity and residual effects of the ready-to-use toxic baits Success 0.02CB (0.24 g of active ingredient [a.i.] per liter of spinosad) and Gelsura (6 g of a.i./liter of alpha-cypermethrin) and to compare them with other food lures containing spinosad and malathion mixed with hydrolyzed protein (Biofruit 5% and Flyral 1.25%), Anamed without dilution or sugarcane molasses (7%) against adult C. capitata in laboratory and greenhouse trials. Ceratitis capitata adults were highly susceptible to all toxic bait formulations (mortality > 80%) until 96 h after exposure. The lowest LT50 (hours) of toxic baits were 2.32 (Gelsura at 4,000 mg/liter), 4.26 (Gelsura at 2,000 mg/liter), 4.28 (Anamed + malathion) and 4.89 (sugarcane molasses + malathion), while formulations containing spinosad (Biofruit, Flyral, Anamed and Success 0.02CB) showed LT50 of approximately 11 h. Without rain, Gelsura (2,000 mg/liter) and all spinosad formulations provided mortality superior to 80% 14 d after application. Gelsura and Anamed + spinosad showed higher resistance to a 5-mm simulated rain, similar to Anamed + malathion, while the other formulations had its efficacy decreased. All toxic baits were effective on adult C. capitata in residual experiments without rain while Anamed + spinosad caused high adult mortality after 5 to 25 mm rains. Gelsura and Anamed + spinosad can be used to replace toxic baits containing malathion for C. capitata population management.

The re-establishment of four legumes, Stylosanthes guianensis cv. Schofield, Lotononis bainesii cv. Miles, Desmodium intortum cv. Greenleaf and Macroptilium atropurpureum cv. Siratro by oversowing into a Setaria anceps cv. Kazungula stand was studied in plots with different phosphate (P) levels. Half the plots had received different levels of initial P only, seven years previously, the other half received initial and maintenance P plus a further application at oversowing. At 15 weeks after sowing all species had similar seedling densities (10 to 23 plants m-2). The densities of stylo and siratro declined over the 88 week trial, and desmodium also declined except at the highest rate of P. Lotononis density increased except at Nil P where all legumes, except stylo, were almost eliminated. In terms of legume survival and growth, setaria tiller density, and P concentration in plant tops, residual effects of P applied seven years previously were clearly evident, particularly at the higher rates (44 and 88 kg P ha-1). P and N concentrations in tops were linearly related.
