Design/methodology/approach: A qualitative research approach was adopted where in-depth semi-structured interviews were conducted with purposively selected female senior manager...

Rooibos tea, traditionally consumed by Indigenous populations, is naturally caffeine-free and contains unique polyphenols with strong antioxidant, anti-inflammatory and anti-hyperglycaemic properties. As such, a systematic review was conducted following PRISMA 2020 guidelines (PROSPERO ID: CRD42023467829) to evaluate the potential association betwe...

Based on the shared expertise of two research entities at the Cape Peninsula University of Technology (CPUT) a transdisciplinary (TD) research approach was adopted to investigate whether Rooibos an indigenous South African plant with its unique bioactive compounds modulates oxidative stress and potentially acts as an ergogenic supplement. Due to th...

The research ethics committee (REC) is a key element of university administration and has gained increasing importance as a review mechanism for those institutions that wish to conduct responsible research, along with safeguarding research ethics standards, scientific merit and human rights of participants. Given the critical role of the university...

Equivocal findings exist for the economy associated with load carried close to the body's centre of mass. Individual variation could explain some of the equivocal findings. This research aimed to examine the extent of individual variation in loaded walking economy. Eighteen females carried load on the back, head and split between the front and back...

This study investigated whether rooibos herbal tea Aspalathus linearis has an ergogenic effect during a fatiguing arm strength test to exhaustion. Thirty-two male participants were randomised in a single blinded, cross-over placebo controlled study in which they ingested standardised rooibos or placebo capsules for four weeks prior to a fatiguing e...

It has been suggested that freedom of movement in the trunk could influence load carriage economy. This study aimed to compare the economy and sagittal plane trunk movements associated with three load carriage methods that constrain posture differently. Eighteen females walked at 3 km.h⁻¹ with loads of 0, 3, 6, 9, 12, 15 and 20 kg carried on the ba...

Professional sport organisations, especially football clubs have been historically characterised by committed and loyal support from local communities an example of such a relationship can be traced to 1888, when the leading Scottish club Celtic FC implemented a unique governance system that included allowing their fans to have a say in the running...

This research investigated the relationship between Corporate Social Responsibility (CSR) and organisational performance at Ajax Cape Town FC a professional football club in the South African Premier Soccer League (PSL). The data collected suggested that Ajax Cape Town FC employed CSR initiatives and consequently enjoyed various benefits from these...

It is recognized that a driving prerogative for any corporation is to make profits, however this fiscal ambition must be balanced with an understanding of broader moral responsibilities in a world characterized by huge economic disparities, with poverty signaling the nadir of this continuum. The argument forwarded here is that while it would be goo...

The purpose of this study was to compare the kinetic responses associated with ground reaction force measurements to both head-loading and back-loading in a group of Xhosa women. Altogether, 16 women were divided into two groups based on their experience of head-loading. They walked over a force plate in three conditions: unloaded or carrying 20 kg...

The Extra Load Index (ELI) has been proposed as a suitable method of assessing the relative economy of load carriage systems. The purpose of this study was to determine, based on empirical evidence, that the ELI can accommodate variations in both body composition and added load. In total, 30 women walked carrying loads of up to 70% body mass at sel...

Although contrasting evidence exists in the literature as to the economy of head-loading, there is a notion that head-loading is an extremely economical method of load carriage. This has become known as the ‘free ride’ hypothesis and, although untested, it is widely accepted. The purpose of this study was to test the ‘free ride’ hypothesis for head...

The aim is to quantify the physiological cost of head-load carriage and to examine the 'free ride' hypothesis for head-load carriage in groups of women differing in their experience of head-loading. Twenty-four Xhosa women [13 experienced head-loaders (EXP), 11 with no experience of head-loading (NON)] attempted to carry loads of up to 70% of body...

Many companies rely on research to ensure market relevance and to optimise their profit making potential. The paper examines the legal-moral dimensions that constitute corporations and considers how these relate with bioethics, notably the 'four principles approach' autonomy, beneficence, non-maleficence and justice. There appears to be an inherent...

The purpose of this study was to compare the subjective perceptual responses to both head-loading and back-loading in a group of Xhosa women. Thirty two women were divided into three groups based on their experience of head-loading and walked on a treadmill on two occasions, head-loading and back-loading, at a self selected walking speed for 4 min...

Although the influence of weight-bearing activity on bone mass has been widely investigated in white women, few studies have been conducted in black, African populations. We investigated bone mineral density (BMD) in black South African women, with and without a history of load-carrying on the head. We also investigated whether load carrying may of...

The physical capacity of emergency care practitioners (ECPs) plays a key role in their ability to carry out rescue and life-saving duties. Irrespective of the emergency scenario males and females are expected to be able to do the same tasks. This study assessed the differences in physical work capacity of male and female emergency care students (EC...

This study investigated the energetics of walking on sand and grass. Fourteen adult males, participated in the study. Participants had a mean age of 34.6 years old, 72.6 kg in mass and 172.5 cm in stature, who walked at 3, 4, 5, 6 and 7 km per h on sand and grass surfaces. Physiological measures included heart rate, O(2) uptake, CO(2) exhalation, v...
