How do muscles get the energy they need for athletic activity?

ATP in muscle cells

In this analysis and discussion activity, students learn how muscle cells produce ATP by aerobic cellular respiration, anaerobic fermentation, and hydrolysis of creatine phosphate. They analyze the varying contributions of these three processes to ATP production during athletic activities of varying intensity and duration.

Students learn how multiple body systems work together to supply the oxygen and glucose needed for aerobic cellular respiration.

Finally, students use what they have learned to analyze how athletic performance is improved by the body changes that result from regular aerobic exercise.

Introduction

A response to “Miss Representation 8 min. trailer:” Changing gender stereotypes by increasing visibility of female athletes

Submitted by jmorgant on Sun, 10/30/2011 - 8:13pm

The trailer for Miss Representation by filmmaker Jennifer Siebel Newsom describes the power of the media, acknowledging that people learn more from it than any other single source of information. The media is the primary force that shapes our society: “politics, national discourse, and children’s brains, lives, and emotions” (Jim Steyer, CEO, Common Sense Media). Upwards of one billion people use the Internet every day (Marissa Mayer, Vice President, Consumer Products, Google); images are widely available and accessible without restrictions.

The messages disseminated by the mainstream media are pervasive, and more often than not emphasize and perpetuate harmful gender stereotypes. According to Miss Representation, women hold only 3% of clout positions in telecommunications, entertainment, publishing and advertising and comprise just 16% of all writers, directors, producers, cinematographers and editors. Because women are generally not the ones deciding how they are represented in the media, they are often shown as sex objects, valued by their looks rather than their achievements. As a result, “girls are taught that their value is based on how they look, and boys are taught that that’s what’s important about women” (Jean Kilbourne, EdD, Filmmaker, Killing Us Softly).
