Elite athletes are particularly susceptible to sleep inadequacies, characterised by habitual short (<7 hours/night) and poor quality (eg, fragmentation). Athletic performance is reduced a night or more without sleep, but the influence on of partial restriction over 1–3 nights, real-world scenario, remains unclear. Studies investigating in often suffer from inadequate experimental control, lack females questions concerning validity chosen assessment tools. Research only scratches surface...
Professional boxing is a combat sport categorized into series of weight classes. Given the sport’s underpinning culture, boxers’ typical approach to “making weight” usually via severe acute and/or chronic energy restriction and dehydration. Such practices have implications for physical performance also carry health risks. This article provides case-study account outlining more structured gradual helping professional male boxer make 59-kg superfeatherweight division. Over 12-week period,...
We have investigated the effects that sleep restriction (3-h during two consecutive nights) on an evening (17:00 h) submaximal weightlifting session; and whether this performance improves following a 1-h post-lunch powernap. Fifteen resistance-trained males participated in study. Before experimental protocol commenced, 1RM bench press inclined leg normative habitual were recorded. Participants familiarised with testing protocol, then completed three conditions nights of prescribed sleep: (i)...
This study investigated the relationships between coach, parent, and peer motivational climate participants' life skills development in youth sport. In total, 308 participants (Mage = 14.67, SD 2.20) completed a survey assessing (mastery ego) their sport (teamwork, goal setting, social skills, emotional problem solving decision making, leadership, time management, interpersonal communication). Multiple regression analyses found that peer-created mastery-climate had strongest positive...
Muscle force production and power output in active males, regardless of the site measurement (hand, leg, or back), are higher evening than morning. This diurnal variation is attributed to motivational, peripheral, central factors core and, possibly, muscle temperatures evening. study investigated whether decreasing resting rectal morning values, by immersion a water tank, leads becoming equal values motivated subjects. Ten healthy males (mean ± SD: age, 22.5 1.3 yrs; body mass, 80.1 7.8 kg;...
Muscle force production and power output in active males, regardless of the site measurement (hand, leg, or back), are higher evening than morning. This diurnal variation is attributed to motivational, peripheral central factors, core and, possibly, muscle temperatures evening. study investigated whether increasing morning rectal resting values, by passive warm-ups, leads becoming equal values motivated subjects. Ten healthy males (mean ± SD: age, 21.2 1.9 yrs; body mass, 75.4 8 kg; height,...
To examine alterations in muscle contractile properties, cortical excitability, and voluntary activation as a consequence of 20 d repetitive endurance cycling within 22-d period.Eight well-trained male cyclists completed prolonged stages interspersed by two rest days (days 9 17), which replicated the 2007 Tour de France route schedule. Isometric knee extensor torque EMG responses vastus lateralis response to percutaneous electrical stimulation transcranial magnetic were measured before, on...
Abstract Background and Aims The use of whole‐body cryotherapy (WBC) for athletic recovery is becoming increasingly popular despite the lack evidence supporting dosage parameters in its implementation. aim current study was to investigate dose–response effects WBC following match‐play elite rugby league players. Methods We observed endocrine (salivary cortisol testosterone) biochemical (creatine kinase) responses three separate post‐match periods Comparisons were made between a single...
The present study investigated the magnitude of diurnal variation in back squat and bench press using MuscleLab linear encoder over three different loads assessed benefit an active warm-up to establish whether could be negated. Ten resistance-trained males underwent (mean ± SD: age 21.0 1.3 years, height 1.77 0.06 m, body mass 82.8 14.9 kg) sessions. These included control morning (M, 07:30 h) evening (E, 17:30 sessions (5-min standardized at 150 W, on a cycle ergometer), one further session...
We have investigated the magnitude of circadian variation in Isokinetic and Isometric strength knee extensors flexors, as well back squat bench press performance using MuscleLab force velocity transducer. Ten resistance-trained males (mean±SD: age 21.5 ± 1.1 years; body mass 78.3 5.2 kg; height 1.71 0.07 m) underwent a) three to four familiarization sessions on each dynamometer b) at different times day (03:00, 09:00, 15:00 21:00 h). Each session was administered a counterbalanced order...
Purpose: Examine changes from 90-minutes of competitive match-play in countermovement jump (CMJ), creatine kinase (CK) and urine osmolality (Uosm) elite football players over a season their association to match external load.Methods: Eighteen footballers participated. CMJ, CK Uosm were collected 24-h pre-match 48-h post-match. Match-performance data was examined using Prozone®.Results: Post-match concentrations increased 49% (ES:0.66), while CMJ flight-time (FT), flight-time:contraction time...
Abstract The aim of this study was to assess left ventricular (LV) function and cardiac biomarkers in response repetitive endurance cycling over 22 days. Ten trained male cyclists (mean± s : age 40±5 years, V O 2max 56±4 ml · kg −1 min ) completed the 2007 Tour de France route. Before, during, 2 days after Tour, all participants underwent an echocardiographic examination determine ejection fraction, as well systolic (S′), early diastolic (E′), late (A′) myocardial tissue velocities, together...
Rugby league carries a high injury incidence with 61% of injuries occurring at tackles. The ball carrier has higher than the defender, therefore understanding mechanisms during injurious tackles are important. Given dynamic, open nature tackling, characteristics influencing tackle outcome likely encompass complex networks dependencies. This study aims to identify important classifying related and non-injurious events in rugby capability correctly classify those events. Forty-one were...
We have investigated the magnitude of diurnal variation in back squat and bench press performance using MuscleLab force velocity transducer. Thirty resistance-trained males (mean ± SD: age 21.7 1.4 years; body mass 80.5 4.5 kg; height 1.79 0.06 m) underwent two sessions at different times day: morning (M, 07:30 h) evening (E, 17:30 h). Each session included a period when rectal temperature (Trec) was measured rest, 5-min standardized 150 W warm-up on cycle ergometer, then defined programme...
Purpose:Investigate football-induced fatigue during hypoxia on RS and perceptual-cognitive skills.Methods: Ten semi-professional footballers underwent a control session (0-m) to quantify in non-fatigued state; three sessions (0-m;1500-m;3000-m) examining skills for given physical workload. The mean number of correct responses (%) anticipation decision-making accuracy were obtained at the 30-min mark each half. HR, TC, RPE %O2sat measured warm-up, test.Results: different between conditions...
Disaster response in the field is typically very strenuous, difficult work, both physically and mentally. While hard evidence lacking, it may be inferred that disaster providers lacking appropriate physical fitness are at increased risk of injury or compromising safety operations during a deployment. This problem amplified depending on where has occurred. For example, deploying to large-scale international disaster, particularly developing country under austere conditions, often brings...
Rugby league has a relatively high injury risk, with the tackle having greatest propensity. The number of tackles players engage in, prior to injurious may influence which yet be investigated. Therefore, this study investigated if rugby are involved in more (as either tackler or ball carrier) (i) 10 minutes, (ii) 1-min periods an tackle-event, (iii) differences for carriers vs. tacklers, and (iv) forwards backs. Video analysis was utilised quantify rate 10-min 61 tackle-related injuries. One...
