Win, Draw, Or Lose? Global Positioning System-Based Variables’ Effect On The Match Outcome: A Full-Season Study On An Iranian Professional Soccer Team, Hadi Nobari, Norbert Keshish Banoocy, Rafael Oliveira, Jorge Pérez-Gómez

Research outputs 2014 to 2021

The aim of the study was to determine the between-match and between-halves match variability of various Global Positioning System (GPS) variables and metabolic power average (MPA) in competitions, based on the match results obtained by professional soccer players over a full season. Observations on individual match performance measures were undertaken on thirteen outfield players competing in the Iranian Premier League. The measures selected for analysis included total duration, accelerations in zones (AccZ1, 2, and 3), decelerations in zones (DecZ1, 2, and 3), and MPA collected by the Wearable Inertial Measurement Unit (WIMU). The GPS manufacturer set the thresholds for the …

The Bench Press Grip Width Does Not Affect The Number Of Repetitions Performed At Different Velocity Loss Thresholds, Alejandro Pérez-Castilla, Ivan Jukic, G. Gergory Haff, Amador García-Ramos

Research outputs 2014 to 2021

© 2021 by the authors. Licensee MDPI, Basel, Switzerland. This study aimed (I) to compare the number of repetitions that can be completed to failure (XRM) and before reaching a 15%, 30%, or 45% velocity loss threshold (XVLT) in the bench press exercise performed using different grip widths, and (II) to examine the inter-individual variability in the percentage of completed repetitions with respect to the XRM when the set volume is prescribed based on a fixed number of repetitions (FNR) and several velocity loss thresholds (VLT). Nineteen men performed four separate sessions in a random order where there was a …

Power Output, Cadence, And Torque Are Similar Between The Forward Standing And Traditional Sprint Cycling Positions, Paul F. J. Merkes, Paolo Menaspà, Chris R. Abbiss

Research outputs 2014 to 2021

Purpose:

Compare power output, cadence, and torque in the seated, standing, and forward standing cycling sprint positions.

Methods:

On three separated occasions (ie, one for each position), 11 recreational male road cyclists performed a 14 seconds sprint before and directly after a high-intensity lead-up. Power output, cadence, and torque were measured during each sprint. Results: No significant differences in peak and mean power output were observed between the forward standing (1125.5 ± 48.5 W and 896.0 ± 32.7 W, respectively) and either the seated or standing positions (1042.5 ± 46.8 W and 856.5 ± 29.4 W; 1175.4 ± 44.9 W …

Large Reductions In Match Play Physical Performance Variables Across A Professional Football Season With Control For Situational And Contextual Variables, Matthew Springham, Sean Williams, Mark Waldron, Darren Burgess, Robert Usher Newton

Research outputs 2014 to 2021

This investigation examined match play physical performance across a professional football season using a multicamera computerized tracking system. A linear mixed-effects model, controlling for situational and contextual variables, identified decreases in team average total distance (TD): season quarter 1 (Q1) (11,047 m) > season quarter 2 (Q2) (10,473 m) ( = ; ES = ), season quarter 3 (Q3) (10,449 m) ( < 0.001; ES = ), and season quarter 4 (Q4) (10,385 m) ( < 0.001; ES = ); work rate (WR): Q1 (115 m/min) > Q3 (108 m/min) ( < 0.001; ES = ), Q4 (107 m/min) ( < 0.001; ES = ); Q2 (109 m/min) > Q4 (107 m/min) ( = 0.003; ES = ); high-speed running distance (HSR): Q1 (1,051 m) > Q2 (813 m) ( = 0.006; ES = ); number of high-speed runs (NHSR): Q1 (87) > Q2 (65) ( …

The Effects Of An Eight Over Cricket Bowling Spell Upon Pace Bowling Biomechanics And Performance Within Different Delivery Lengths, Samuel J. Callaghan, Robert G. Lockie, Warren A. Andrews, Walter Yu, Robert F. Chipchase, Sophia Nimphius

Research outputs 2014 to 2021

Pace bowlers must often perform extended bowling spells with maximal ball release speed (BRS) while targeting different delivery lengths when playing a multi-day match. This study investigated the effect of an eight over spell upon pace bowling biomechanics and performance at different delivery lengths. Nine male bowlers (age = 18.8 ± 1.7 years) completed an eight over spell, while targeting different lengths (short: 7–10 m, good: 4–7 m, full: 0–4 m from the batter’s stumps, respectively) in a randomized order. Trunk, knee and shoulder kinematics and ground reaction forces at front foot contact (FFC), as well as run-up velocity and …

Change In Knee Flexor Torque After Fatiguing Exercise Identifies Previous Hamstring Injury In Football Players, Cameron Lord, Fadi Ma'ayah, Anthony J. Blazevich

Research outputs 2014 to 2021

Muscular fatigue and interlimb strength asymmetry are factors known to influence hamstring injury risk; however, limb‐specific exacerbation of knee flexor (hamstrings) torque production after fatiguing exercise has previously been ignored. To investigate changes in muscular force production before and after sport‐specific (repeated‐sprint) and non‐specific (knee extension‐flexion) fatiguing exercise, and explore the sensitivity and specificity of isokinetic endurance (ie, muscle‐specific) and single‐leg vertical jump (ie, whole limb) tests to identify previous hamstring injury. Twenty Western Australia State League footballers with previous unilateral hamstring injury and 20 players without participated. Peak concentric knee extensor and flexor (180°∙s⁻¹) torques were …

The Manipulation Of Pace Within Endurance Sport, Sabrina Skorski, Chris Abbiss

Research outputs 2014 to 2021

In any athletic event, the ability to appropriately distribute energy is essential to prevent premature fatigue prior to the completion of the event. In sport science literature this is termed “pacing.” Within the past decade, research aiming to better understand the underlying mechanisms influencing the selection of an athlete’s pacing during exercise has dramatically increased. It is suggested that pacing is a combination of anticipation, knowledge of the end-point, prior experience and sensory feedback. In order to better understand the role each of these factors have in the regulation of pace, studies have often manipulated various conditions known to influence …

Chambers, Robert Gardiner, Brad Wall, Prue Cormie, Kate Bolam, Daniel A. Galvao

Research outputs 2014 to 2021

Background

Physical exercise mitigates fatigue during androgen deprivation therapy (ADT); however, the effects of different exercise prescriptions are unknown.

Objectives

To determine the long-term effects of different exercise modes on fatigue in prostate cancer patients undergoing ADT.

Design, setting, and participants

Between 2009 and 2012, 163 prostate cancer patients aged 43–90 y on ADT were randomised to exercise targeting the musculoskeletal system (impact loading + resistance training; ILRT; n = 58), the cardiovascular and muscular systems (aerobic + resistance training; ART; n = 54), or to usual care/delayed exercise (DEL; n = 51) for 12 mo across university-affiliated exercise clinics …
