Abstract
Isometric exercises are frequently prescribed to patients by Osteopaths. The aim of thisstudy was to investigate the effects of maximal isometric contractions had on hamstring strength.
Twenty-two asymptomatic subjects, eight male and fourteen female, aged between 20 and 35, were recruited from the forth year student body at The British College of Osteopathic Medicine. Subjects performed isometric exercises to the hamstring muscle five days a week for two weeks. Each exercise involved sustaining knee flexion isometrically for a duration of six seconds and repeated six times with a thirty second rest in between each contraction held. Strength was measured as peak force using the digital myograph 2000. Measurements were taken two days prior to the training programme and then two days after the programme finished.
Statistical analysis using paired T-tests demonstrated a significant increase (p<0.05) in isometric strength (peak force) of the hamstring muscle within the experimental group. It was also found that there was a significant decrease (p<0.05) in isometric strength 0(peak force) within the control group. Unpaired T-tests conducted on males and females within the experimental group demonstrated that females increased significantly in strength (p<0.05), whilst males showed an insignificant increase in strength (p>0.05).
It was concluded that regular isometric exercises over the duration of two weeks to the hamstring muscle group is effective in increasing strength.
