Physical activity in university health science students: Motivations influencing behaviors.

To understand how competence, self-efficacy, enjoyment and motivation relates to physical activity behavior during transition from school to university. Health science students ( = 558) studying first year biology at an Australian university. Cross-sectional correlational survey design using five self-report questionnaires to establish relationships between a physical activity index and motivational variables.

Repeated-sprint ability and team selection in Australian football league players.

Purpose: To investigate the relationship between selected physical capacities and repeated-sprint performance of Australian Football League (AFL) players and to determine which physical capacities contributed to being selected for the first competition game.

Methods: Sum of skinfolds, 40-m sprint (with 10-, 20-, 30-, and 40-m splits), repeated-sprint ability (6 × 30-m sprints), and 3-km-run time were measured during the preseason in 20 AFL players. The physical qualities of players selected to play the first match of the season and those not selected were compared.

Effects of starting strategy on 5-min cycling time-trial performance.

The importance of pacing for middle-distance performance is well recognized, yet previous research has produced equivocal results. Twenty-six trained male cyclists (VO2 peak 62.8 +/- 5.

The effects of short-term sprint training on MCT expression in moderately endurance-trained runners.

The purpose of this study was to assess the effects of short-term sprint training on transient changes in monocarboxylate lactate transporter 1 (MCT1) and MCT4 protein and mRNA content. Seven moderately endurance-trained runners (mean +/- SE; age 27.7+/-2.

Anthropometric and biomechanical field measures of floor and vault ability in 8 to 14 year old talent-selected gymnasts.

The aim of this study was to identify the anthropometric and physical prerequisites for high difficulty floor tumbling and vaulting. Twenty 8-14 year old female talent-selected gymnasts performed handstand push-offs, and single and multiple jumps on a portable Kistler force plate. The force curves were analysed using Kistler and Excel software to obtain peak displacement, peak take-off force, and power The gymnasts were also assessed for sprinting, with and without vaulting, and standing broad jump performances.

.VO2 is attenuated above the lactate threshold in endurance-trained runners.

Purpose: To determine whether a deviation from linearity occurs in the .VO2-speed relationship, above the lactate threshold (LT) in running; and whether the length of the submaximal exercise bouts alters the magnitude of any deviation.

Methods: Ten endurance-trained runners (N = 3 state level, N = 4 club level, and N = 3 recreational) (mean +/- SE; age 24.
