The paper "Comparing the Difference in Energy Expenditure in the Treadmill and Rower Machine"  is a worthy example of a term paper on sports and recreation.   Exercise plays a major role in human health; it is associated with a decreased risk of chronic heart disease. Physical activity is an underlying problem solver to all prolonged diseases such as blood pressure, diabetes, and obesity many issues appears to be related to a sedentary lifestyle, measured as either energy expenditure or minutes of physical activity ( Moyna et al. , 2001; Vathsangam et al. , 2011). Exercise may be entertaining and sustained as an enjoyable experience if people select activities that results in a high rate of energy expenditure.

Indoor cardio equipment or exercise machines have become critical tools that people use to achieve goals of physical exercise activities. The different exercise machines promote different modes of exercise, thereby enabling individuals to have a chance to select the appropriate machines with the capability to address their physical exercise needs. Moreover, physical trainers are keen to have indoor cardio equipment that has the ability to satisfy trainee needs, a situation that calls for the evaluation of different cardio equipment available for indoor exercises.

Guided by this, the aim of this paper is to compare two exercise machines: treadmill and rower machine, in terms of the difference in energy expenditure. A number of studies have been conducted in which case differences among the exercise machines have been established. For example, a study by Zeni, Hoffman & Clifford (1996a), examined indoor exercise machines with regard to energy expenditure at given ratings of perceived exertion. The study compared major exercise machines such as treadmill, rowing ergometer, combined cycle/arm ergometer, cycle ergometer, stair stepper, and cross-country skiing simulator (Zeni, Hoffman & Clifford, 1996a).

The study was able to establish that rates of energy expenditure were able to change as much as 261 kcal/hour; for the exercise machines (Zeni, Hoffman & Clifford, 1996a). This was particularly notable when subjects in the research were able to exercise at self-selected work rates that were categorized as fairly light, relatively hard, and hard. Observation drawn from the above study was that treadmill came out with the greatest energy expenditure, then rowing and stair-stepping ergometers came second, while the cycle and combined cycle/arm ergometers came last in terms of values derived (Deuster, 1997).

Therefore, the conclusion that can be drawn from the study is that if exercise intensity is established by perceived effort, then treadmill running or walking has the ability to result in greater energy expenditure and a stronger cardio-respiratory training stimulus for any given duration of exercise as compared to other exercise modalities (Zeni, Hoffman & Clifford, 1996a). In a related study by the same researchers, Zeni, Hoffman & Clifford (1996b), using the same six modes of exercise equipment, it was established that for any given rating of perceived exertion (RPE), the treadmill stimulates relatively higher heart rates (HRs) when compared to other modes such as stationary cycle and the rowing machine.

On the other part, the cycling machine stimulates the lowest HR. With regard to blood lactate concentration, the study established the existence of a similar relationship between blood lactate concentration with RPE in all exercise machines, and only cross-country skiing simulator had different results (Zeni, Hoffman & Clifford, 1996b).
