Study summary

The majority of today's youth do not engage in enough physical activity (PA) to maintain good health. Low PA levels are associated with poor health (e.g. diabetes, high blood pressure) and early mortality. Girls are less likely than boys to be active, and their rates of participation drop off more steeply during adolescence. Girls report many barriers to exercise, including transportation issues and feeling self-conscious about their appearance and abilities. School-based PA programs that try to improve health, mainly through aerobic exercise and education, have had a small effect to date. However, the few programs that included resistance training as the focus showed strong improvements in health related measures. In this project, we will examine the effect of a female strength and conditioning specialist on decreasing barriers and increasing the overall health of high school girls, with the delivery of in-school, girls-only resistance training programs. We will see if physical and mental health changes with the training, and how the presence of the S \& C specialist affects the girls' social interactions within the school. The results will help individuals in the education sector plan programs and services to improve overall youth and school health.

What researchers measure

Primary outcomes

  1. 1 Repetition Maximum leg press

    Time frame: Change from Baseline and at 8 weeks

Secondary outcomes

  1. 1 Repetition Maximum bench press

    Time frame: Baseline and at 8 weeks

  2. Grip strength dynamometry

    The average of three repetitions for each hand will be used in analysis

  3. mCAFT for aerobic fitness

    Time frame: Baseline and at 8 weeks

  4. Physical activity levels

    Average daily minutes spent in Sedentary, Low, Moderate and Vigorous intensity activity over 5 days will be measured via an accelerometer worn around the waist.

    Time frame: Baseline and at 8 weeks

  5. Physical Self-Perception Profile

    36 item questionnaire; scores for embedded scales of "Strength Competence", "Physical Self-Worth", "Global Self-Worth", and "Attractive Body Adequacy" will be calculated.
