The Soul swimming cap designed specifically for long hair, afro, and dreadlock hair was banned by the swimming body FINA at the Tokyo Olympics. The ban was due to the cap not following the natural form of the head and the possibility the Soul cap could increase swimming performance. The ban attracted considerable media attention and backlash online...
The use of inertial devices in sport have become increasingly common. The aim of this study was to examine the within-day validity and reliability of a relatively new inertial measurement unit at measuring basketball movement parameters. Eighteen well-trained basketball players completed several individual performance tests including linear running...
Pulmonary rehabilitation improves the health of people with chronic obstructive pulmonary disease (COPD). Community-based maintenance programmes led by health professionals maintain these benefits; however, limited information is available on volunteer-led community programmes. We investigated the impact of a post-rehabilitation volunteer-led progr...
The demands of national and international professional rugby union matches are well established, however, there has not been a comparative study investigating running demands in New Zealand teams playing in club (amateur), Heartland Championship (semi-professional Div 2), the Mitre 10 Cup (semi-professional Div 1) or Super Rugby (professional) comp...
University athletes are unique because they not only have to cope with the normal psycho-physiological stress of training and playing sport, but they also need to accommodate the stress associated with their academic studies along with considerable stress from their social environment. The ability to manage and adapt to stress ultimately helps impr...

Busbridge, AR, Hamlin, MJ, Jowsey, JA, Vanner, MH, and Olsen, PD. Running demands of provincial women's rugby union matches in New Zealand. J Strength Cond Res XX(X): 000-000, 2020-There has been rapid growth in participation in women's rugby but there is minimal research on the sport. The aim of this study was to increase our knowledge of the runn...
Takamori, S, Hamlin, MJ, Kieser, DC, King, D, Hume, P, Yamazaki, T, Hachiya, M, and Olsen, PD. Senior club-level rugby union player's positional movement performance using individualized velocity thresholds and accelerometer-derived impacts in matches. J Strength Cond Res XX(X): 000-000, 2020-Game demands of professional rugby union players have be...
Objectives: Neopterin has been used as a stress marker in team sport athletes, but its use
in monitoring stress in hypoxic training requires further investigation. The objective of this
study was to determine whether neopterin measures could detect differences between
hypoxic and normoxic training stress and whether such levels could predict subseq...
Background: Children today in developed countries have an abundance of discretionary, cheap,palatable and ready to eat foods available [...]
Background: Nutrition is crucial for optimal performance of athletes. There is limited researchon dietary habits of strength athletes in New Zealand [...]
This study aims to investigate the performance changes in 19 well-trained male rugby players after repeat-sprint training (six sessions of four sets of 5 × 5 s sprints with 25 s and 5 min of active recovery between reps and sets, respectively) in either normobaric hypoxia (HYP; n = 9; FIO2 = 14.5%) or normobaric normoxia (NORM; n = 10; FIO2 = 20.9%...
Many teams and individual athletes prefer to compete at home, thereby benefiting from preparing in familiar surroundings, having easy access to training and coaching staff, close contact with family members and profiting from a positive crowd atmosphere. However there is little empirical evidence to show whether home advantage is beneficial, partic...
The aim of this study was to investigate whether playing rugby at altitude or after travel (domestic and international) disadvantaged teams. In a retrospective longitudinal study, all matches (n=125) played in the 2012 Super Rugby Competition were analysed for key performance indicators (KPI) from coded game data provided by OPTA sports data compan...
Aim:
The relationship between watching major sporting events and cardiac hospital admissions is contentious. This study is the first to investigate cardiovascular admissions during Rugby World Cup (RWC) tournaments.
Methods and results:
New Zealand (NZ) public hospital admissions data were analysed for cardiovascular events during the 1999, 2003...
This study evaluated the impact of a high-intensity strength training session on rowing sprint performance. Ten male club rowers performed a baseline counter-movement jump (CMJ) and a 250 m rowing ergometer sprint (250 m). Twenty-four hours after baseline, participants performed a high-intensity strength training session (ST) consisting of multi-jo...

There is limited published research on the practices of strength and conditioning (S &C) coaches in Great Britain. Information about training program design would be useful in developing models of good practice and ecologically valid intervention studies. The aim of this research was to quantify the training practices of coaches responsible for the...
Limited research has been performed on competitive bouldering. The aim of this study was to quantify the movement dynamics of elite boulder climbers. Six climbers were filmed during a national competition consisting of 5 novel climbing problems or routes. Two problems were randomly selected and film footage was analyzed using Kandle Swinger Pro sof...
The aims of the study were to (a) determine the high-intensity activity patterns of soccer players at different performance levels and playing positions, (b) investigate temporary and end game fatigue in elite domestic and international soccer matches, and (c) quantify acceleration and maximal running speed profiles of elite soccer players. Elite d...
The aims of this study were to (1) determine the activity profiles of a large sample of English FA Premier League soccer players and (2) examine high-intensity running during elite-standard soccer matches for players in various playing positions. Twenty-eight English FA Premier League games were analysed during the 2005-2006 competitive season (n=3...
The purpose of this study was to compare the acute effects of different modes of stretching on vertical jump performance. Eighteen male university students (age, 24.3 +/- 3.2 years; height, 181.5 +/- 11.4 cm; body mass, 78.1 +/- 6.4 kg; mean +/- SD) completed 4 different conditions in a randomized order, on different days, interspersed by a minimum...
Athletes in sports requiring explosive movements might benefit from a unique form of training in which a limb is restrained while the athlete attempts ballistic (explosive) movements. We investigated the effects of such ballistic training and conventional resistance training on force and speed of front kicks, side kicks, and palm strikes of martial...
