Attacks by stray dogs, interference by bystanders or other pedestrians or acts of God will invalidate any given walk which would then have to be repeated to ensure the reliability of the results.
It is the hypothesis of this experiment that a researcher will require more time to complete 500 steps walking uphill than walking on a similar surface that is level.
Results
The results of the three walking experiments on the level sidewalk and the 15-degree hill were compared using a chi-square analysis.
An analysis of the averages and standard deviations is an appropriate analytical technique for this experiment because it provides a researcher with a useful test as to whether frequencies of the phenomena observed match the frequencies that might be expected to occur by chance.
All times were converted from minutes and seconds recorded on the field worksheet into total seconds required for each walk for use with the statistical analysis program for ease of comparison.
The results of the three walking field experiments on the 15-degree hill and the level sidewalk are shown in Table 1 below.

Conclusion
The results of this simple experiment confirmed the hypothesis that walking uphill would require longer, and therefore more physical intensity of movement, than walking on a similar surface that was level.
The preparation of the instrumentation, the development of the procedures and the execution of the steps involved were enlightening from both a research methodology perspective as well as in terms of improving physical fitness.
This approach was found to be a good way to introduce researchers to the steps involved in developing a simple experiment and presenting the findings in an interesting fashion to a wide range of audiences.
Vitamin D Supplementation increases Voluntary Physical Activity Levels in Nursing Home Patients Over the course of a semester does vitamin D3 supplementation, and the resultant increase in muscle strength and bone density, lead to increased physical activity in nursing home residents in the absence of added encouragement? The elderly often suffer from low serum levels of vitamin D, reduced muscle strength, and decreased bone density (reviewed in: Hamilton, 2010). Muscle biopsies have
Congestive Cardiac Failure Mr Ward is a 71-year-old male who reports feeling a non-radiating, "heavy" discomfort in the lower retrosternal and epigastric region particularly when he bends over or walks short distances. He also reports a further 7 days of dyspnoea during moderate exertion. On examination his blood pressure was 165/95 mm HG, pulse 90 -100 bpm, respiratory rate of 24 with inspiratory crackles at both lung bases. The following blood
In other words, sports participation may actually discourage some children from being physically active. Another current intervention is to reduce the amount of time that a child spends in front of a screen of some sort. Screens, whether computer screens, video game screens, or television screens all encourage children to be passive recipients of entertainment, rather than active players in a game of some sort. What is fascinating is that
This is achieved through the increase of metabolic rates and lean body mass while eliminating excess fat and burning calories. While the required amount of physical activity differs based on the caloric intake and body type, sports can assist an individual to maintain a healthy weight. For people who want to maintain a huge amount of weight loss, high-intensity sports can be the best option while reasonably-intensive physical activity
Community Outing Risk Report: Touring Old Mesilla The outing proposed needs to be a four hour tour for a group of 20 individuals with varied backgrounds, experience, and physical abilities. It needs to be an outdoor activity. The people in the group include four people in the 60-70-year range (three males and one female) two females over the age of 75, both of whom have health problems, four children between the
Practical Research Finding Implementation and Experimentation Stage -- Phase I The experimenter did not set out to determine specifically which of the various contributing factors (or combinations of factors) identified by the empirical research of medial tibial stress syndrome was most responsible for the experimenter's symptoms. However, since the initial attempts to resolve the symptoms incorporated changes to all of the external variables except a change in running surface, the experimenter
