The effect of backward locomotion training on the body composition and cardiorespiratory fitness of young women.

This study investigated the effect of a backward training program on the physical and fitness condition of young women. Twenty-six healthy female university students (aged 18 - 23 years) took part in three different baseline tests: body composition, a submaximal treadmill test, and a 20-m shuttle run test. Subjects were divided into a training group (n = 13) and a control group (n = 13). The training group completed a six-week backward run/walk training program. The control group was restricted to their daily activities similar to the four weeks prior to the onset of the baseline tests. The training group showed a significant (p = 0.01) decrease in O(2) consumption during both submaximal forward and backward exercise on the treadmill (32 % decrease during backward and 30 % decrease during forward exercise). A significant (p = 0.01) decrease in percentage body fat (2.4 %), a 19.7 % decrease in the sum of skinfolds (p = 0.001) and significantly (p = 0.013) improved predicted VO(2max) values from the forward 20-m shuttle run test (5.2 %) were also found in the case of the training group. The findings suggest that backward walk/run training improves cardiorespiratory fitness for both forward and backward exercise and causes significant changes in body composition in young women.

Relationship between adherence to exercise and scores on extraversion and neuroticism.

A sample of 116 subjects were classified as adherers or drop-outs on the basis of exercising at an on-campus exercise facility over 1 yr. Scores on the Eysenck Personality Inventory showed that adherers did not differ from drop-outs in scores on extraversion; however, drop-outs recorded significantly higher neuroticism scores than adherers.
