1.0 Fatigue Hypothesis Fatigue can be defined as extremely tiredness resulting from mental or physical exertion or illness. Based on my first journal by van Dieen, Luger and van der Eb (2011), the purpose of the research is to test the hypothesis that fatigue due to exercise will affect the trunk stability in elite female gymnasts. The method that they used is three trials of a balancing task while sitting on a seat fixed over a hemisphere. Before the research started, all of the gymnasts were instructed to handstand on an uneven bar to make their trunk muscle fatigue. On this study, they used force plate to trace the center of pressure (CoP).
Title: Determine how mass affects the way an object is pulled by gravity Aim: To find out the effect of mass on the falling time of an object from a specific height. In this experiment we will be dropping three different balls with different masses from a specific height and recording the time it takes to hit the ground. Hypothesis: The ball that is heavier/has more mass will hit the ground faster than balls that are less heavy/have less mass. Materials: • One 1m ruler • Three different balls with different masses (softball, hollow plastic ball, and ping-pong ball • Stop watch Variables: Independent: • Mass of each of the balls will not change after various trials Dependent: • Time it takes for the ball to hit the ground might be different after each trial Controlled: • Height at which ball is dropped • Ball dropped at rest/initial speed Method/Procedure: 1. Support 1m ruler vertically against the wall 2.
Ernest Tang 8E (16) Base Jumping Science Summative Lab Research Question: How does the drop height of (4.5m ,5m ,5.5m,6m and 6.5m) affect the drop time of the base jumping experiment? This is to see if my parachute works safely. I would record the time of the fall and see if it would be too fast. If it takes less time to land when released at a higher point, this means that the parachute is not safe. Hypothesis: If the drop height is higher, than the drop time would be longer.
The vertical jump measurement was determined as the difference between these two points combined with their mass. Individual maximum pushing force and direction of force were recorded objectively using a custom-built scrum machine. Each player’s fatigue and scrum effort were measured using a Visual Analogue Scale (VAS) and a Borg Rating of Perceived Exertion (RPE) Scale, respectively. Both scales were completed before scrumming and after each successive scrum. An ‘X’ was placed along the 10cm VAS ranging from no fatigue to most fatigue experienced, according to how the player was feeling.
Research by Hoigaard et al. (2010) in Norway with 110 elite level, women handball players on 10 seperate teams supported previous research that role satisfaction (i.e., satisfaction with the athlete’s formal task-related role on the team) would mediate the relationship between perceived role ambiguity (i.e., lack of clear information about one’s position and the expectations) and the athletes’ willingness to engage in social loafing (the phenomenon when an individual athlete displays less motivation followed by exerting less effort towards a task when engaged and operating collectively in a group or team sport than when working alone (Eccles & Turner, 2014)). The plethora of research also supports a negative association between social loafing
The simulation exercise gave me a perfect opportunity to communicate with new colleagues ( friends ) as a National NGO. I have more courage to express my thoughts and perspectives on the role given. The time stress and atmosphere in simulation teached me that I have to speak Clear and specific due to the limited time to work, I have to listen very carefully since sometimes everyone seems to speak so quickly, the heavy rain and voices can divert
Athlete’s that don’t prepare don’t tend to succeed and they never tend to use them. The second part is that the athlete must train and maintaining a high level of intensity before every drill in practice and the same intensity in every performance. Without this the body won’t be able to perform consistently and efficiently for long
Following the Involvement Load Hypothesis proposal, many investigation have tried to examine the accuracy of the claim made by Laufer and Hulstijn(2001).In this section some of studies will be discussed to elucidate the tenacity of the ILH. Hulstijn and Laufer (2001) conducted a study testing whether retention of vocabulary acquired incidentally is conditional upon the amount of task-induced involvement. The subjects were advanced English foreign language (EFL) learners in the Netherlands and Israel, divided in three groups in each country, every group was assigned to one task. Three tasks were designed to test the hypothesis. Task 1 consisted of reading a text equipped with marginal L1 glosses to target words.
