Assess the influence of a 20% reduction in game time on the volume and intensity of elite AF players' match activity profiles. GPS technology was used to analyse the movement demands of 45 AF players from the same AFL club during 43 matches across the 2019 and 2020 seasons. GPS data were categorised into measures of volume (total match time [TMT] a...

Background Repeat power ability (RPA) assessments are a valuable evaluation of an athlete’s ability to repeatedly perform high intensity movements. Establishing the most reliable and valid loaded jump RPA assessment and method to quantify RPA has yet to be determined. This study aimed to compare the reliability and validity of an RPA assessment per...

The purpose of this case study was to quantify the contribution of the arms in the sprint start and compare the difference in force and velocity characteristics when arm forces are not accounted for. One elite student athlete performed 6 starts with the same block position whilst forces were measured independently for front and rear legs and left a...

PURPOSE When comparing or prescribing loads for single leg (SL) squat or jump movements there is a tendency to assume that the load will be half of what an athlete performs in the double leg (DL) movement. Whilst this is a reasonable starting point, the reality is that the SL movement is more challenging and we cannot make this assumption. AIMS The...

Background High volume power training (HVPT) involves high volumes of high-velocity resistance training, with the aim to improve repeated high-intensity efforts (RHIEs). Repeat power ability (RPA) is the ability to repeatedly produce maximal or near maximal efforts. Assessments of RPA using external loading may determine the ability to perform repe...

Rugby Sevens, a new Olympic sport, features high intensity intermittent running and contact efforts over short match durations, normally six times across two to three days in a tournament format. Elite Rugby Sevens seasons often include over a dozen competitive tournaments across less than nine months, demanding deliberate and careful training-stre...

The purpose of this study was to examine the differences in performance and heart rate responses between a high heat outdoor condition (34.0°C, 64.1% humidity) and a temperate indoor condition (22.0°C, 50.0% humidity) during the 30-15 intermittent fitness test (30-15IFT). Eight highly trained Rugby Union players (28.1 ± 1.5 years, 181.4 ± 8.8 cm, 8...
