The Effects Of Bag Style On Muscle Activity Of The Trapezius, Erector Spinae And Latissimus Dorsi During Walking In Female University Students, R. Hardie, R. Haskew, J. Harris, Gerwyn Hughes
Kinesiology (Formerly Exercise and Sport Science)
Back pain is common in adolescents which has been associated with carrying a bag. However, there is little research examining the effects of bag style in female adolescents. The aim of the study was to investigate the effects of different bag conditions on muscle activity of the trapezius, erector spinae and latissimus dorsi muscles in female university students during walking. Twelve female university students walked on a treadmill for 5 minutes at 1.1 m/s during five conditions; control, 1 strapped rucksack, 2 strapped rucksack, ipsilateral shoulder strap and contralateral shoulder strap, each containing 10% bodyweight. Electromyography for the trapezius, erector …

Kinesiology (Formerly Exercise and Sport Science)
Objectives: The purpose of the study was to examine gender differences in lower limb muscle activity during jump landing and rapid change of direction. Equipment and Methods: Surface electromyography (EMG) of the rectus femoris, biceps femoris and gluteus maximus were recorded for 10 male and 10 female basketball, volleyball or netball players performing five repetitions each of two tasks; 1) landing from a maximal height vertical jump and, 2) 45º rapid change of direction on their dominant leg. Independent sample t-tests were conducted to determine sex differences and paired samples t-tests were conducted to determine task differences in peak EMG …
