School Workload and Sleep Deprivation in Adolescent Tardiness Research Paper - 3

School Workload and Sleep Deprivation in Adolescent Tardiness - Research Paper Example this study are the dependency at participants’ honesty, inability to directly manipulate the participants’ daily workload and sleep time, inability to manipulate â€Å"time of school† as sub-variable of school workload, and the inconclusiveness on the effects of increasing school workload to adolescent tardiness. Further larger-scale researches on school workload and sleep deprivation in committing tardiness is being aimed by this study. No experimental research so far was conducted on the effects of school workload and sleep deprivation in tardiness. However, two experimental literatures, plus three supporting non-experimental studies, will be used by this study to serve as guides in formulating the design of this study to be conducted for the first time. The experimental study Sustaining Female Helicopter Pilot Performance with Dexedrine during Sleep Deprivation (Caldwell, Caldwell & Crowley, 1997) investigated the effects of a stimulant drug dextroamphetamine on the flight stimulator performance of sleep-deprived female aviators. The sample participants were exposed to 40-hour sleep deprivation, but the experimental group received the drug while the control received a placebo. The independent variable is the drug administration while the dependent variables are the performance, level of alertness and mood of the participants. They found out that the experimental group is able to sustain performance, alertness and mood than the control group. This study provides a good background information on the effects of sleep deprivation that the drug is hypothesized to eliminate: poor performance, lower level of alertness and lower mood. This study provides a hypothesis that sleep deprivation affects student’s performance, which includ es tendencies of being tardy. Another experimental study, The impact of Cross-Training and Workload on Team Functioning: A Replication and Extension of Initial Findings (Cannon-Bowers et al, 1998). Other than cross-training, they

Healthful Eating for Weightlifters - Essay Example The awareness for such healthy outlook is more universal now than ever before. There are more fitness camps, more gyms in the neighborhood, more health and fitness equipment and facilities, and those who do not have access to these or do not feel their need have viable alternatives in aerobics and yogic stances. (Robert J. Buresh, MS, et al). The first step towards the achievement of good health and physique is proper diet and exercise. This paper is focused on healthful eating for weightlifters. As such, we are going to concentrate on those muscles that help weightlifters. There are muscles for activities such as marathon runners. These muscles are made up of Type 1 fibres and are ideally suited for runners and other activities of aerobic nature. The Type 2 fibre muscles develop for the purpose of short bursts of energy and are ideal for weight lifters. (Jonny Bowden). Therefore, the diet and exercises for weightlifters are framed after examining two factors. Factor number one is the weightlifter. Diet and exercise comprise factor number two. In order to satisfy the criteria for factor number one, the weightlifter's age, sex, height, weight, body mass index, present state of health, health history, and disability (if any) are recorded. The recording of data for factor number two will include present diet and physical activities, heart beat and pulse rates, calories level, and health related problems (if any). 4. Healthy Eating and Exercises It may not be possible to obtain the complete regimen of diet and exercise suitable for a particular person in one day. Getting hold of the regimen is the first step. Gradually, the process may undergo changes as the weightlifter continues on the diet and workouts, and upgrades to diets and physical activities which help in performance improvements. As a first step, the regimen comprises the following. 4.1 Nutrition The nutrition that results from dietary intake in our bodies is necessary for all of us. The body will simply collapse without nutrition. It is necessary for our health. Nutrition helps combat diseases, and cushions the effects of fatigue. It is important that the weightlifter consumes diet of the right nutritional value to suit his needs. The diet has got to be such that the conversion of body fat into muscle is easily achieved when combined with exercise. 4.2 Essential to Long Life A diet that provides healthy nutrition is essential for long life which is free from sickness and infirmities. It is important for the weightlifter to bear in mind a positive lifestyle is one of the key ingredients in performance improvement issues. Performance is not only related to diet and exercises but it is a matter of the mind as well. After
