A resource aimed at GCSE or A-Level biology, physical education or applied science students, this worksheet provides a series of instructions to investigate the effect of exercise on blood pressure, heart rate and cardiac output. The worksheet includes a weblink to an online metronome for students to standardise their rate of exercise (e.g. squats)and also provides a graphic to gauge whether blood pressure is optimal or above normal. Key words: blood pressure, sphygmomanometer, exercise, heart rate, cardiac output, recovery

A worksheet aimed at GCSE biology or applied science students, this resource provides a basic introduction to the concept of respiration and the movement of reactants and products into and out of cells. The worksheet also includes a table requiring students to research the uses of energy that is supplied by respiration. Useful as an introduction to the topic or as a recap of what has already been learnt previously. Key words: respiration, energy, carbon dioxide, oxygen, glucose, cells

A resource aimed at advanced biology, applied science or physical education students, this worksheet provides several questions that lead students through the topic of blood doping. Lance Armstrong is used as a contextual example of an athlete that has been disgraced following the revelation that he was involved in blood doping; the worksheet provides questions on the effect of EPO, the impact on blood cell counts and how haematocrit tests could be used to provide evidence. The worksheet also has follow up questions on the use of steroids and diuretics in sports. Key words: Sports, Blood, doping, haematocrit, EPO, steroids, diuretics, lance armstrong, blood volume, steroids

A resource aimed at advanced level biology, applied science or physical education students, this worksheet comprises of a series of questions that discuss the nature of an ECG and its interpretation. The worksheet also includes questions on abnormal ECG traces and diagnosis of conditions such as tachycardia and bradycardia. A useful resource to use as a lesson starter or plenary once this topic has already been taught.

A worksheet aimed at high ability GCSE or Level 3 Physical Education or Applied Science students, this resource provides eighteen 'what am I' questions that relate to the topic of respiration. The questions probe knowledge that is slightly above GCSE but not quite at the level of advanced biology. A useful exercise to set as a plenary of key vocabulary, as a starter task recapping a previous lesson or as a homework challenge.
