Relationships between muscle fibre characteristics and physical performance capacity in trained athletic boys
1991
The relationships between muscle fibre characteristics and the physical performance capacity of trained athletic boys (aged 11-13 years) were studied over 2 days. The subjects were divided into two groups according to muscle fibre distribution. The 'fast' group (FG) comprised 10 subjects (sprinters, weightlifters, tennis players) with more than 50% fast-twitch fibres (type II), and the 'slow' group (SG) comprised 8 subjects (endurance runners, tennis players, one weightlifter) with more than 50% slow-twitch fibres (type I) in their vastus lateralis muscle. The 'fast' group had 59.2 +/- 6.3% and the 'slow' group had 39.4 +/- 9.8% type II fibres. Other clear differences (P less than 0.05-0.01…
Key Physical Factors in the Serve Velocity of Male Professional Wheelchair Tennis Players
2021
The aim of this study was to identify the physical factors related to serve speed in male professional wheelchair tennis players (WT). Nine best nationally-ranked Spanish male wheelchair tennis players (38.35 ± 11.28 years, 63.77 ± 7.01 kg.) completed a neuromuscular test battery consisting of: isometric handgrip strength
Neuromuscular, metabolic and hormonal profiles of young tennis players and untrained boys.
1989
This study compared the neuromuscular, metabolic and hormonal profiles of trained prepubescent tennis players and an untrained group. The boys in the experimental group (n = 9; mean age +/- S.D. = 11.4 +/- 0.5 years) had participated in tennis training for 2.3 +/- 1.0 years and the boys in the control group (n = 9; mean age +/- S.D. = 10.9 +/- 0.4 years) were normal active volunteers. The tennis players were found to be physically more active than the controls when the comparison was made for either 1 year (4.9 +/- 1.8 vs 2.6 +/- 2.5 times per week; P less than 0.05) or for 1 week (3.4 +/- 1.2 vs 0.4 +/- 0.5 times; P less than 0.001) preceding the tests. Choice reaction time was significant…
Predicting domain-specific actions in expert table tennis players activates the semantic brain network.
2018
Motor expertise acquired during long-term training in sports enables top athletes to predict the outcomes of domain-specific actions better than nonexperts do. However, whether expert players encode actions, in addition to the concrete sensorimotor level, also at a more abstract, conceptual level, remains unclear. The present study manipulated the congruence between body kinematics and the subsequent ball trajectory in videos of an expert player performing table tennis serves. By using functional magnetic resonance imaging, the brain activity was evaluated in expert and nonexpert table tennis players during their predictions on the fate of the ball trajectory in congruent versus incongruent…
Application of Infrared Thermography in the Assessment of Sport Equipment
2019
Abstract Infrared thermography is a noninvasive imaging technique used to determine surface temperatures under controlled conditions. This technique has many applications in different fields, the assessment of sport equipment being one of them. This chapter aims to provide a general overview of the scientific literature regarding the application of infrared thermography for the assessment of sport equipment. Some examples are provided based on the recent literature and the background experience of the chapter authors in the use of infrared thermography in sport. Examples include the monitoring of formula one (F1) tires during racing, detection of technological doping in cycling, saddle fit …
Supination control increases performance in sideward cutting movements in tennis.
2013
The objective of this study was to explore the effects of tennis shoe characteristics on performance during sideward cutting movements followed by direction changes. Five tennis players (age = 21.5 +/- 0.8 years, mass = 75.2 +/- 2.8 kg, and height = 1.78 +/- 0.05 m) participated in the study and 10 tennis shoes were tested. Several footwear mechanical parameters were analyzed: Shore A hardness, longitudinal and transverse flexibility, midsole height at heel, presence of heel counters, and weight. A force plate was used to measure the kinetic variables, and two video cameras were used to perform a three-dimensional photogrammetric analysis. Results revealed that subject-footwear interaction …
Fitness testing in tennis: Influence of anthropometric characteristics, physical performance, and functional test on serve velocity in professional p…
2021
The aims of this study were to examine the relationship between anthropometric variables, physical performance, and functional test with serve velocity regarding tennis players’ level and to design regression models that effectively predict serve velocity. A sample of sixteen male tennis players participated in this study (national level = 8, professional level = 7). Anthropometric measurements (body mass, height, body mass index and body segments) and physical test (hand strength, countermovement jump, jump on serve, and serve velocity) and functional test (medicine ball throw overhead and shot put) were performed. No differences in anthropometrics and physical test were found between nati…
Stroke Analysis in Padel According to Match Outcome and Game Side on Court
2020
The aim of this study was to analyze the distribution of padel strokes, their effectiveness, direction, and court zone, comparing between the winning and losing pairs in the match and the playing side of the players. The sample included 8441 strokes corresponding to 1055 points out of a total of nine padel matches in the First National Category. The variables analyzed were type of stroke, court area, effectiveness and directions of the strokes, match outcome, and game side. Matches were analyzed through systematic observation. The results showed that the winning pair made a significantly higher percentage of winners, and cross-court smashes and volleys from the offensive zone. In addition, …
The relationship between professional tournament structure on the national level and success in men's professional tennis.
2003
This article discusses the relationship between a nation's men's professional tennis tournament structure and that nation's success in the international men's game. The 2002 men's professional tennis tournament calendar provided the distribution of events on the top thirty nations. Criteria for a nation's success in men's professional tennis were: nation's number of players with ATP points, nation's number of players in the top 200 ranking, and the combined ATP ranking of a nation's top 5 male players. Pearson correlations were performed between the number of tournaments and each criterion. Results showed a considerable variation in the number of events ranging between 67 (United States) an…
