Measuring tackle and ruck technique in rugby union
Background: Developing tackle and ruck technique is important to improve performance in matches and reduce the risk of injury. Little is known regarding valid tools to assess tackle and ruck technique in rugby union. The aims of this thesis were (1) to assess the validity and representativeness of …

The effect of an exercise intervention on insulin sensitivity, insulin secretion and insulin clearance in black obese South African women
… present with low insulin sensitivity (SI) and hyperinsulinemia, the latter due to high insulin secretion and reduced clearance. In addition, they exhibit lower levels of central and ectopic fat, compared to their white counterparts, contradicting the known correlates of SI typically …

The relationship between reported coaching behaviours and learning resources on youth rugby players' attitudes towards injury prevention and performance in the tackle
Background: Involvement in sports has numerous well-documented physiological and psychological benefits but also carries a risk of injury. Due to the contact nature of Rugby, involvement in the game carries a greater risk of injury compared to other sports. The tackle phase of the game has resulted …

Physiological evaluation of sleep surfaces in healthy volunteers and patients with acute-upon-chronic lower back pain
… in the sitting position results in reduced back and leg pain, centralisation of pain and reduced erector spinae muscle activity in patients with lower back pain (LBP). While the positive effects of a lumbar support in sitting have been studied, few researchers have attempted to document the value …
