The purpose of this study was to determine the relationships between velocity, stroke length, and rate in freestyle competitive events order compare male female swimmers' results assess their with anthropometric characteristics. Three hundred three 325 swimmers national international levels were tested during competition. Solutions adopted each event had specific characteristics affecting rate/stroke length ratio according distance race. Differences velocity men women primarily resulted from...

By addressing numerous statistical, theoretical, and methodological weaknesses of existing research on chronic fatigue syndrome (CFS), this study attempted to examine closely whether cognitive dysfunction in CFS patients is restricted slowed information processing or it extends less efficient attentional selectivity. In an online study, 83 healthy controls (all French-speaking volunteers) first completed the Multidimensional Chronic Asthenia Scale then performed two-to-one version Stroop...

Abstract Background The intermittent fasting period of Ramadan is associated with reductions in training volumes and intensities to maintain physical fitness levels reduce injury occurrence. Accordingly, it might be beneficial include neuromuscular (NMT) applied during avoid detraining promote prevention soccer players. This study aimed analyze NMT effects on the young Methods Forty highly-trained male players (U17/U19) were randomly assigned a (n = 20) or traditional soccer-specific group...

The purpose of the study was to identify stroking characteristics such as rate and length used by male swimmers differing skill analyze variations velocity, stroke rate, during course race. performance 442 subjects including 40 competing at an international 100-m freestyle event videotaped later analyzed measure on each lap Stroke seemed be best predictor swimming velocity. Different levels could discriminated especially length, throughout Besides higher values for were characterized...

J Strength Cond Res 33(6): 1570-1579, 2019-This study investigates the physiological/physical responses a simulated mixed (MMA) competition over hours. Twelve fighters performed MMA competition, consisting of three 5-minute matches. Physiological/physical data were assessed before (Trest), directly after round 1 (Trd1), 2 (Trd2) 3...

Abstract Sangnier, S, Cotte, T, Brachet, O, Coquart, J, and Tourny, C. Planning training workload in football using small-sided games density. J Strength Cond Res 33(10): 2801–2811, 2019—To develop the physical qualities, games' (SSGs) density may be essential soccer. Small-sided are which pitch size, players' number, rules different to those for traditional soccer matches. The purpose was assess relation between SSGs' 33 densities data (41 practice 3 full games) were analyzed through global...

Abstract Background The pre-season preparatory period is considered key for optimizing the physical fitness levels needed to withstand congested match periods and preventing injuries during regular soccer season. This study contrasted effects s of neuromuscular training (NMT) versus an endurance-dominated (ET) program conducted preseason on measures injury occurrence in female players. Methods Twenty-four players aged 17.0 ± 1.3 years from a professional club participated this study. Players...

There is little known about return to sport and performance after anterior cruciate ligament (ACL) tear in high-level alpine skiers.To analyze the parameters that influence an ACL French skiers from 1980 2013.Descriptive epidemiology study.The study population included 239 male 238 female who competed on national ski team for at least 1 season between 2013 speed (downhill super-G) technical disciplines (giant slalom slalom). Two groups were formed: group (G1) athletes had sustained rupture,...

This study determined the validity and reliability of a new specific field test that was based on scientific data from latest research.Seventeen international-level karatekas participated in study: 14 men (age 24.1 ± 4.6 y, body mass 65.7 10.8 kg) 3 women 19 3.6 54.1 0.9 kg). All performed karate-specific (KST) 2 times (test retest sessions were carried out separated occasions 1 wk apart). Thirteen also laboratory to assess maximal oxygen uptake (VO2max).Test-retest results showed KST be...

The relationship between foot kinematics and the development of lower extremity musculoskeletal disorders (MSD) has been focus recent attention. However, most studies evaluated static type not dynamic function. purpose was to compare limb kinematics, plantar pressures during gait in physically active individuals with pronated non‐pronated Foot function 154 adult participants documented as (n = 63) or neutral 91) using 2 established methods: Posture Index Center Pressure Excursion Index....

Objective: The aim of the present study was to examine effect Cold Water Immersion (CWI) on recovery physical performance, hematological stress markers and perceived wellness (i.e., Hooper scores) following a simulated Mixed Martial Arts (MMA) competition. Method: Participants completed two experimental sessions in counter-balanced order (CWI or passive for control condition: CON), after MMAs competition (3×5-min MMA rounds separated by 1-min rest). During CWI, athletes were required...

The authors investigated and compared the energy expenditure postural coordination of two groups healthy subjects on a mechanical horse at 4 increasing oscillation frequencies. Energy was assessed from oxygen consumption, respiratory quotient, heart rate values, characterized by relative phase computations between (elbow, head, trunk) horse. results showed that riders better adapted (i.e., maintenance in-phase antiphase) than nonriders, but remains same. Likewise, we observed an system...

The aim of this study was to examine the effects two different sprint-training regimes on sprint and jump performances according age in elite young male soccer players over course one season.Players were randomly assigned training groups. Group 1 performed systematic change-of-direction sprints (CODST, U19 [n = 9], U17 U15 10]) while group 2 conducted linear (LST, 9]). Training volumes similar between groups (40 per week x 30 weeks 1200 season). Pre post training, all tests for assessment...

The aim of this study was to investigate the effects listening preferred music during a warm up or exercise, on performance 6-min all-out exercise test (6-MT) in young adult males. Twenty-five healthy males volunteered participate study. Following within subject design, participants performed three conditions (MDT: test; MDW: warm-up; WM: without music) random order. Outcomes included mean running speed over (MRS6), total distance covered (TDC), heart rate responses...
