Purpose: The aim of this review was to examine the effects of various factors, including recovery time, conditioning activity, range of motion, gender, age, fiber type percentage, training experience, and supplement intake, on post-activation potentiation (PAP) and post-activation performance enhancement (PAPE). After clarifying the differences bet...

BACKGROUND In the last decades, emerging evidence has shown that muscle growth is not homogeneous along a muscle head. This phenomenon is known as regional muscle hypertrophy and has led to several questions regarding the implications it may have for health and sports performance. OBJECTIVE The aim of this study was to determine whether regional h...

To investigate differences in the game demands of top-level professional basketball players based on their position and the quarter of the game. Thirteen elite male players were assessed on their positions (point guard, guard, forward, and centre) over different quarters (Q1-Q4) during 15 home games. A multivariate analysis of variance was performe...

Specific physical qualities such as sprint running, change-of-direction or jump height are determinants of sports performance. Photocell systems are practical and easy to use systems to assess the time from point A to point B. In addition, these photoelectric systems are also used to obtain the time of vertically displaced movements. Knowing the ac...

Background: The aim of the present study was to compare the effects of active (AR) vs. passive recovery (PR) between two Wingate Anaerobic Tests (WAnT) on power output, blood lactate (BLa) and oxygen consumption (VO2) in a second WAnT. Methods: Twelve well-trained cyclists underwent three experimental sessions. In the first session, they complet...

The aim of the present study was to analyse the role of exercises' resistance profile in regional hypertrophy. Thirty-eight healthy women completed a 9-week resistance training program consisting of either 4 sets of 12 repetitions to volitional failure of inclined bicep curls (INC group) or preacher curls (PREA group), three times per week. Pre- an...

During the last years, post-activation performance enhancement (PAPE) has gained notorious popularity due to the capacity to improve the acute rate of force development (RFD) using different strategies with different muscle contraction regimes as conditioning stimuli. The aim of the present study was to analyse the role of a maximal isometric post-...

Background: The relationship between stiffness and drop jump performance in athletes in various stages of development has yet to be fully investigated. The first aim of this study was to investigate the association between the stiffness of the patellar and quadriceps tendon (PT, QT), gastrocnemius-Achilles tendon unit (GAT), and rectus femoris (RF...

The aim of this study was to describe the effects on collective behaviour and the physical response of young elite football players (Under 15) in the same 11 versus 11 task in three different pitch lengths (100, 75 and 50 m, LSG100, LSG75 and LSG50, respectively), keeping the width constant (60 m). The intra-team variables were: convex hull (CH), s...

Purpose The aim of the present study was to analyse the role of exercises' resistance profile in regional hypertrophy. Methods 39 healthy women completed a 9-week resistance training program consisting of either 4 sets of 12 repetitions of inclined bicep curls (INC group) or preacher curls (PREA group) three times per week to muscle failure. Pre- a...

This study aimed to compare four standard deviational ellipse models to assess directional behavior and player activity area in four small-sided games (SSG) of soccer played on pitches with the same width (40 m) and different lengths (30, 40, 50, and 60 m). Fourteen participants played four 7-a-side SSGs on each of the four pitch sizes. Based on GP...

There is emerging evidence suggesting that muscle growth is not homogeneous through the muscle. The aim of the present study was to analyse the role of exercise selection in regional hypertrophy. Two randomly allocated groups with equal training volume and intensity performed squats in the smith machine (SMTH group) or the leg extension exercise (L...

A literature search was performed in 2 databases (PubMed and Scopus) on May 22, 2019. From the 14 studies included in the review, 13 found that the anatomical cross-sectional area of some regions of a muscle increased to a greater degree than others. Some studies found increases in the distal region, others reported increases in the middle region,...

It was recently demonstrated that musculoarticular (MA) stiffness is related to sprint cycling performance in nonfatigued conditions. This study examined whether relatively stiffer cyclists were more effective at sprinting under fatigued conditions, as occurs during endurance cycling competitions. MA stiffness of the quadriceps was assessed in 21 t...

Crank torque (CT) application and rate of CT development (RCTD) are important considerations in sprint cycling. The stiffness of the musculotendinous unit is related to the isometric rate of torque development (RTD); however, this relationship has yet to be examined in sprint cycling. Maximal isometric torque (MIT) and isometric RTD of the quadrice...

In cycling, a circular pedaling action makes the most useful contribution to forward propulsion. Training with independent cranks (IC) has been proposed to improve the pedaling action. The aims of this study were, first, to assess whether the intermuscular coordination pattern of the pedaling action with normal cranks (NC) is modified after a train...

An isometric maximal voluntary contraction (iMVC) is mostly used for the purpose of EMG normalization, a procedure described in the scientific literature in order to compare muscle activity among different muscles and subjects. However, the use of iMVC has certain limitations. The aims of the present study were therefore to propose a new method for...
