Purpose: (1) To analyze the effects of postactivation performance enhancement (PAPE) induced by upper-limb flywheel resistance training on serve velocity and accuracy in tennis players, (2) to compare the effects of 2 different protocols (low load [LL] vs high load [HL]), and (3) to examine whether PAPE effects are influenced by tennis players' neuromuscular performance.

Methods: Fifteen young competitive tennis players completed 1 familiarization and 3 testing sessions in a randomized order. In the control session, participants performed a warm-up protocol followed by serve-velocity and -accuracy tests.

Range of Motion and Muscle Stiffness Differences in Junior Tennis Players with and without a History of Shoulder Pain.

Background: Due to its significant unilateral predominance, tennis can provoke functional and morphological asymmetries that develop over time and may result in undesired morphological alterations.

Hypothesis/purpose: The goals of this study were a) to assess glenohumeral range of motion and muscular stiffness in young tennis players with and without a history of shoulder pain and b) to examine interlimb asymmetries in these variables in both groups. It was hypothesized that players with a history of shoulder pain would show a reduced glenohumeral internal rotation (IR) and total arc of motion (TAM) and increased stiffness in internal rotator muscles compared to those without shoulder pain.

Countermovement jump (CMJ), sprint time (5, 10, and 15 m), change-of-direction (COD) performance (right and left), medicine-ball throws (overhead, forehand, and backhand), and serve velocity were included as tests at baseline, week 4, and week 8.

Inter-Limb Muscle Property Differences in Junior Tennis Players.

The goal of this study was to investigate side-to-side differences and asymmetries regarding muscle characteristics in young tennis players. Thirty-four participants performed contractile property measurements (stiffness, tone, elasticity and time to relaxation) on the dominant and non-dominant extremities including nine muscle groups involved in the kinetic chain of main tennis strokes. Significant differences (p≤0.

Effects of isoinertial or machine-based strength training on performance in tennis players.

The objective of this study was to analyze the effects of two 8-week neuromuscular training (NMT) interventions on selected physical indicators in young tennis players. Twenty-four junior male tennis players were assigned to a machine-based (MG) (n = 8), flywheel (FG) (n = 8) or a control training group (CG) (n = 8). Tests at baseline, week 4 and 8 included: countermovement jump (CMJ); speed (S; 5, 10, 15 m); agility (right [AR] and left [AL]); serve velocity (SV) and medicine ball throws (MBT; overhead [O], forehand [FH], backhand [BH]).

Determinant Physical Factors of Tennis Serve Velocity: A Brief Review.

Purpose: To review the main physical aspects that could positively or negatively influence serve velocity (SV).

Methods: An examination of existing literature including studies analyzing positive (biomechanical aspects, anthropometrics, range of motion, strength, and power) and negative (competition-induced fatigue) associations to SV are summarized in this review.

Results: Aspects such as lower-leg drive, hip and trunk rotations, upper-arm extension, and internal rotation seem to be the major contributors to racquet and ball speed.

Force-Time Curve Variable Outcomes Following a Simulated Tennis Match in Junior Players.

This study examined the alterations induced by a simulated tennis competition on maximal isometric voluntary contraction (MVC), peak rate of force development (PRFD) and rate of force development (RFD) at different stages of contraction. Twenty junior tennis players performed an 80-minute simulated tennis match and two (pre and post) muscular performance tests.
