BACKGROUND: Paediatric sports injuries are common. Fortunately, most children self-modulate their activity levels when injured until they recover, but some will seek medical help. Injury pattern varies with age, mechanism and the chosen sport. OBJECTIVE: The aim of this article is to give a general overview of some of the more common paediatric sports injuries, including common patterns of pathogenesis, the effects of growth and biomechanics on tissue load, and issues particular to specific sports...

Despite the growing interest in Paralympic sport, the evidence-base for supporting elite wheelchair sport performance remains in its infancy when compared to able-bodied (AB) sport. Subsequently, current practice is often based on theory adapted from AB guidelines, with a heavy reliance on anecdotal evidence and practitioner experience. Many principles in training prescription and performance monitoring with wheelchair athletes are directly transferable from AB practice, including the periodisation and tapering of athlete loads around competition...

The present study aimed to quantify the demand of seven generic, closed agility drills. Twenty males with experience in invasion sports volunteered to participate in this study. They performed seven, closed agility drills over a standardised 30-m distance. Physical demand measures of peak velocity, total foot contacts, peak impacts, completion time, and maximum heart rate were obtained via the use of wearable sensor technologies. A subjective rating of perceived exertion (RPE) was also obtained. All measures, with the exception of maximum heart rates and RPE were able to delineate drills in terms of physical and physiological demand...

Muscle glycogen is the predominant energy source for soccer match play, though its importance for soccer training (where lower loads are observed) is not well known. In an attempt to better inform carbohydrate (CHO) guidelines, we quantified training load in English Premier League soccer players (n = 12) during a one-, two- and three-game week schedule (weekly training frequency was four, four and two, respectively). In a one-game week, training load was progressively reduced (P < 0.05) in 3 days prior to match day (total distance = 5223 ± 406, 3097 ± 149 and 2912 ± 192 m for day 1, 2 and 3, respectively)...

PURPOSE: To investigate the variation in training demands, physical performance, and player well-being across a women's soccer season. METHODS: Seventeen elite female players wore GPS tracking devices during every training session (N=90) throughout 1 national-league season. Intermittent high-speed-running capacity and 5-, 15-, and 25-m-sprint testing were conducted at the beginning of preseason, end of preseason, midseason, and end of season. In addition, subjective well-being measures were self-reported daily by players over the course of the season...

The investment in learning required to reach benefit with weightlifting training is currently not well understood in elite athletes. The purpose of this investigation was to quantify changes in vertical jump power production and kinematic variables in hang power clean (HPC) performance during the learning process from a naive state in a multiple single-subject research design. Four elite athletes undertook HPC learning for approximately 20-30 minutes twice per week over a 169-day period. Changes in parameters of vertical power production during squat jump (SJ) and countermovement jump (CMJ) were monitored from baseline (day 0) and at 3 additional occasions...

In team sports, tactical periodisation refers to the planned manipulation of training loads with the aim of prioritising athlete readiness for matches of greatest importance. Although monitoring of athletes' physical condition is often used to inform this planning, the direct influence of external factors on match difficulty has not been well quantified. In this study, a 'match difficulty index' (MDI) for use in Super Rugby was developed, based on the influence imparted by five external factors on previous match outcomes...

The study aim was to investigate the effect of a periodised pre-season training plan on internal training load and subsequent stress tolerance, immune-endocrine responses and physical performance in tennis players. Well-trained young tennis players (n = 10) were monitored across the pre-season period, which was divided into 4 weeks of progressive overloading training and a 1-week tapering period. Weekly measures of internal training load, training monotony and stress tolerance (sources and symptoms of stress) were taken, along with salivary testosterone, cortisol and immunoglobulin A...

PURPOSE: Elite endurance athletes may train in a polarized fashion, such that their training-intensity distribution preserves autonomic balance. However, field data supporting this are limited. METHODS: The authors examined the relationship between heart-rate variability and training-intensity distribution in 9 elite rowers during the 26-wk build-up to the 2012 Olympic Games (2 won gold and 2 won bronze medals). Weekly averaged log-transformed square root of the mean sum of the squared differences between R-R intervals (Ln rMSSD) was examined, with respect to changes in total training time (TTT) and training time below the first lactate threshold (<LT(1)), above the second lactate threshold (LT(2)), and between LT(1) and LT(2) (LT(1)-LT(2))...

Although numerous authors have studied the effect of different training procedures on athlete's resistance performance, there are no studies on how the improvement of aerobic resistance is affected by the distribution of training loads. This research sets out to analyse the effectiveness on aerobic activity of distributions with a constant load (CON) and with increments in intensity (INC) over a 4-week period. A total of 30 athletes took part in the analysis (38.7 ± 9.8 years; 174.7 ± 6.5 cm; 72.0 ± 9.8 kg)...

Definitions of healthcare promotion were examined from the theory of knowledge regarding its ontological and epistemological aspects as considered by several paradigms. Three-phase periodisation was used. The first distancing regarding the positivist paradigm and healthcare promotion through definitions of public health was made during the background phase (1920-1973). The promotion of healthcare acquired its own identity and became explicit policy in the midst of scenarios involving the confluence of paradigms during the foundational phase (1974-1986)...

This study used transcranial magnetic stimulation to measure the corticospinal responses following 8 weeks of unilateral leg strength training. Eighteen healthy, non-strength trained participants (14 male, 4 female; 18-35 years of age) were matched for age, gender, and pre-training strength; and assigned to a training or control group. The trained group participated in unilateral horizontal leg press strength training, progressively overloaded and wave periodised, thrice per week for 8 weeks. Testing occurred prior to the intervention, at the end of 4 weeks and at the completion of training at 8 weeks...

The physical training undertaken by athletes is one of a set of lifestyle or behavioural factors that can influence immune function, health and ultimately exercise performance. Others factors including potential exposure to pathogens, health status, lifestyle behaviours, sleep and recovery, nutrition and psychosocial issues, need to be considered alongside the physical demands of an athlete's training programme. The general consensus on managing training to maintain immune health is to start with a programme of low to moderate volume and intensity; employ a gradual and periodised increase in training volumes and loads; add variety to limit training monotony and stress; avoid excessively heavy training loads that could lead to exhaustion, illness or injury; include non-specific cross-training to offset staleness; ensure sufficient rest and recovery; and instigate a testing programme for identifying signs of performance deterioration and manifestations of physical stress...

This article analyses the health of workers engaged in oil exploration and exploitation in Colombia during the time of the so-called De Mares concession from 1916 to 1940. Periodisation was constructed which sought to account for yellow fever and tropical diseases within the sanitary situation related to oil exploration and exploitation during this period and region and how it became displaced from its central position by accidentally. The initial period was characterised by the lack of protection to which the workers were subjected at the start of oil-producing activities between 1916 and 1920...

Dual-energy X-ray absorptiometry (DEXA) was used to assess whole body and regional soft tissue mass, fat mass and lean body mass compositional changes in 68 female recruits (age 20.8 +/- 1.14 years; body mass 59.5 +/- 8.79 kg; stature 159.57 +/- 5.53 cm) pre- and post 12-weeks of military basic training. A decrease in total body fat tissue mass (10.2%) and regional percent fat (10.9%) was measured with an increase in total lean body mass (8.7%). Of interest were the differences in the responses in the tissue composition of the arms (16...

International health funders, leaders and researchers frequently cite 'successes' in this field as validation for past labours and justification for future endeavours. However, the question of what constitutes success - from both historical and contemporary perspectives - has been inadequately analysed. This paper reviews and periodises understandings of success in international/global health during the past century and a half, mapping out shifts and continuities over time. It then turns to the implications of these changing conceptualizations for current and future global health ideologies, strategies and activities...
