title: The influence of velocity-based resistance training on strength and power development

authors: Peta, Henare Te Ura Ote Ra

subjects: Technology

abstract: Sports that require high levels of strength and power typically employ traditional percentage-based training methods (%1RM). However, a major flaw to this form of training is that it does not take into account the athletes daily biological status and readiness to train. Therefore, movement velocity has been proposed as a viable method of resistance training to enhance performance. The purpose of this thesis was firstly, to examine literature on the adaptations and current practices of traditional based training (TT, %1RM) and velocity-based training methods (VBT). Secondly, to investigate the reliability of the bar mode application (band attached to the bar) of the PUSH band accelerometer in measuring peak velocity (PV) during the barbell squat jump exercises (SJ), and finally, to investigate the effects of VBT training on neuromuscular strength (back squat [BS], bench press, [BP]) and power (squat jump PV using the PUSH band) in comparison to TT (%1RM). The PUSH band showed high to perfect reliability in PVmax and PVmean across four trials (mean ICC 0.91 & 0.90). The results are in agreement with previous research conducted on the PUSH band accelerometer (when attached to the subject's forearm). No significant differences were found between groups in strength and power measures (p > 0.05). Furthermore, between-group effect sizes were deemed trivial for BS and BP (d = 0.00 and 0.03, respectively), while the effects for PVmax (d = 0.23 ±0.73) and PVmean (d = -0.38 ±0.59) were deemed unclear. Future research should focus on assessing the reliability of the bar mode application on other traditional exercises (BP, BS, deadlifts) at various intensities (20 – 90%1RM). Additionally, future research should utilise a larger sample size and a more homogenous strength/training group in order to determine any potential effects.

title: Biosecurity management overview

authors: Champion, Paul

abstract: Today’s symposium topic is the issue of water weeds in the Rotorua Lakes and their management. I will discuss how and where these weeds came from and how they got into New Zealand. The weeds discussed are only a small sample of potential weeds that could
have additional or even greater impacts on Rotorua and New Zealand as a whole. I will discuss our legislation and how management at the border protects us from future weeds yet to enter this country. Unfortunately, it appears that our legislation has been too
effective at keeping out new plants, with no new aquatic plants legally introduced since the mid 1990’s but over 25% of aquatic plants in the aquarium/pond plant trade appear to have got here illegally. Several prosecutions have resulted from interception of smuggled
plants.
Once inside our border, there are several biosecurity measures initiated that have kept a number of our worst weeds at bay. These include banning the propagation, sale and distribution of 30 aquatic weed species, national and regionally run eradication
programmes for high-risk weeds, with the successful eradication of five species and great progress towards the eradication of around twelve other weeds. However, some of these plants, such as water hyacinth, are still illegally kept by some individuals and several new
infestations have originated from such sources. Despite this, the programmes have successfully kept the volume of deliberate spread for a wide number of aquatic weeds to a trickle.
As previous speakers will have discussed, humans are the major cause of spread of aquatic weeds, with contaminated watercraft and trailers, fishing nets, diggers etc. all contributing to this spread. Bay of Plenty Regional Council have been proactively managing their lakes, identifying which lakes are threatened by which weeds, and then carrying out surveillance in order to detect and manage any new weed incursions. To assist with surveillance, they have designed and constructed weed cordons that effectively net off access points such as boat ramps (the main sites of new weed introduction) and have successfully detected and prevented establishment of new incursions of the weeds hornwort and egeria in Lake Rotoma. Each summer holidays an awareness programme run under the national ‘Check, Clean, Dry’ banner promotes inspection for weeds at boat ramps around the region. Additionally, surveillance of ornamental ponds near to high-value lakes has led to the detection of a number of
potential weeds.

title: Weaving kaupapa Māori and e-Learning

authors: Neal, Terry

subjects: New Zealand

abstract: This paper describes the creation and design of an online professional development course that aims to help educators in New Zealand to weave kaupapa Māori and e-Learning approaches together. The team sought to model weaving of kaupapa Māori and e-Learning approaches in how they worked together and the educational design for the material. The authors propose that educators with these skills are crucial if we are to effectively meet the needs of Māori learners, more than that, of all New Zealand learners, in the 21st century.
