exercise affect your breathing and heart rate?” and my hypothesis was “If you exercise then your heart and breathing rates will go up because your body needs more oxygen to be circulated so that your body can keep up.”. My hypothesis was correct‚ as proven by my test. My partner‚ Brian’s heart rate when it was resting was 56 beats per second and his breathing rate was 40 beats per second. We made him do jumping jacks for ten seconds and his heart and breathing rates both went up. His heart rate increased

How to Match the Color of Your Manicure with the Color of Your Pedicure It is summer and we choose clothes and shoes that will keep us cool in the hot days. That is why this is the season when people show most flesh. And that is when you put on our sandals and show our beautiful toes to the world.

THE GREAT METABOLIC RACE INTRODUCTION During exercise‚ carbohydrates and lipids are required in order to provide energy for the working body. The inherent reduced nature of these compounds allows for partial or complete oxidation in extracting energy in the form of adenosine triphosphate (ATP). The varying chemical structure of the macromolecules evokes different processes for their complete utilisation. This paper seeks to expound on the mobilisation of these fuels‚ the biochemical pathways that

1. Comment how your personal teaching and learning philosophy and beliefs influence the way you see teaching and learning. I have always considered that the place where learning and teaching occur has to be a safe environment for the students and teachers in order to achieve the established goals. I believe teachers have to be aware of students’ needs‚ interests‚ conditions‚ and age. For instance‚ as Brown (2007) explains‚ different age groups require different dynamics and activities to learn the
