How does drinking juice before bed affect how many hours you sleep dependent variable?
A person who drinks juice before bed will sleep less hours than a person who does not drink juice.
How does temperature affect athletic performance?
High heat and humidity lead to two problems in the exercising body: 1) increased core body temperature and 2) dehydration. Increased body temperature (hyperthermia) leads to decreased muscle endurance, which means the muscle’s ability to contract repeatedly or in a sustained manner over long periods of time.
How does cold weather affect sports performance?
Colder muscles mean less efficient, weaker muscles with less stamina . Increased danger of pulling muscles – Warming up before exercise is important to prevent pulling muscles, low temperatures mean that muscles cool down faster and take longer to warm in the first place.
Why is temperature control important in sport?
Your body uses energy to maintain its core temperature. You take control when you make the effort to stabilize that temperature during your game . Thermoregulation allows you to preserve your optimal body temperature, so you deliver the best performance and stay safe at the same time.
How does weather affect football players?
Colder, stiffer muscles that aren’t working as efficiently are also more likely to tear, making strains more common in the cooler weather, according to Finnoff. Experts from ESPN’s “Sport Science” have tested the effects of low temperatures on an athlete’s performance.
Does weather affect football?
Things like snow, wind and cold affect both teams more or less equally and don’t have much of an impact on the point spread or moneyline — but inclement weather has an outsized effect on the total number of points scored by both sides .
What are the effects of ball temperature and ball inflation on collision?
When the ball is heated, it becomes more elastic, as the bonds are able to move more freely and thus are able to stretch more than those in a cooler ball , and thus less energy is lost (Portz, 2011). This then means that the ball bounces higher.
How does temperature affect coefficient of restitution?
temperature of the rubber will result in an increase in Young’s modulus , or in other words, a decrease in the compression distance of the ball. Less energy will be dissipated in each bounce, leading to an increase in the coefficient of restitution.
How do football players stay warm in cold weather?
“We have heated benches and heated foot pads are underneath where the players’ feet go while they’re sitting in order to help keep them warm,” said Taylor. Benches also include helmet warmers, which are perfect for heating up an ice-cold helmet before getting back in the game.
What affects the distance a soccer ball travels?

What effect does high temperature have on the growth of apples hypothesis?
Hypothesis: If we increase the temperature then more apples will grow.
What is the hypothesis of temperature may cause leaves to change color?
A proper hypothesis is written as an If...then... because statement. If leaf color change is related to temperature , then exposing plants to low temperatures will result in changes in leaf color because cooler weather causes a chemical change in the leaf.
How does weather conditions affect sports performance?
The warmer weather allows for more effective use of muscles , and therefore more effective training. Cold weather, by contrast, can put athletes’ bodies at risk of injury, as cold muscles are more susceptible to strains. ... Some Australian athletes suffered severe muscle strains due to having to train in cold conditions.
Does cold reduce athletic performance?
Timothy Miller, a sports medicine specialist and orthopedic surgeon at The Ohio State University Wexner Medical Center, added that joints and muscle tendons become stiffer in colder temperatures. This decreases performance and increases the risk of injury if athletes do not warm up properly.
Does temperature affect exercise?
If you want to increase your muscle strength, doing workouts in the cold probably won’t help. Muscles work best at hot temperatures . When muscles get cold, the force they can produce decreases. You are also more likely to get injured in the cold, but the extra risk of injury is reduced if you warm up properly.
How do cold temperatures affect muscles?
Cold weather causes muscles to lose more heat and contract , causing tightness throughout the body. Joints get tighter, muscles can lose their range of motion and nerves can more easily be pinched, according to Los Angeles-based orthopedic physical therapist Vivian Eisenstadt.
How cold weather affects the body?
Low body temperature can cause your heart , nervous system, and other organs to enter a state of shock, putting a person at risk of a heart attack, respiratory system failure and possibly death. Symptoms of hypothermia include shivering, slurred speech, slow breathing, lack of coordination and confusion.
Does cold weather affect sprinting?
Sprinters tend to have more issues in cold weather because if their muscles aren’t warm enough, they can pull something and have an injury to a hamstring or something. That’s a really common thing: hamstrings or quads, if they aren’t warm enough.”
Do athletes have higher temperature?
In general, athletes are found to have higher body temperatures , which can be related to difficulty falling asleep.
How does hyperthermia happen to an athlete?
Turning up the heat
There are three common causes of hyperthermia in athletes: high exercise intensity, high air temperature and high relative humidity . Any athlete – female or male – who pushes themselves too fast, for too long, in hot and humid conditions can experience performance-degrading hyperthermia.
How does weather affect soccer?
Heavy rainstorms greatly affect a soccer pitch, especially if it’s natural turf. Substantial rainfall can create puddles, muddy areas, and sinkholes on soccer fields. These change the game in a few ways. ... Soccer players often complain that the ball moves too fast when turf is wet.
How does cold weather affect fantasy football?
Teams post 45 more combined rushing yards per game and nearly one full rushing touchdown more; this yields +4.3 fantasy points expected per game for rushing attacks. This appears to be largely a product of play-calling: teams rush more in the snow, to the tune of about 2.5 more rushes per game.
What do football players wear in the rain?
If it’s very cold and rainy, you may need to wear a couple of layers. The most important layer is the one closest to your body.

Why does a football deflate in cold weather?
The “P” is pressure. ... But it proves that, when it’s cold, the pressure inside a football drops . In this specific situation, it could be that some pressure was removed from the balls, and that the 51-degree temperature did the rest. Regardless, when the mercury drops, footballs naturally deflate, at least a little.
What wind speed affects football?
The largest impact will come from wind. Wind is expected to be blowing a consistent 30-35 mph, with gusts reaching over 40 mph. The average wind for an NFL game is under 7 mph . In games with double-digit mph winds, the under hits at over a 55% rate.

How does temperature affect the coefficient of restitution of a tennis ball?
The temperature of the ball influences its coefficient of restitution. A warmer ball will bounce higher than a cold one. ... In a hollow ball, the change in temperature causes a change in air pressure within the ball.
Does temperature affect air pressure?
Cold air is more dense, therefore it has a higher pressure. Warm air is less dense and has a lower pressure associated with it. ... Remember, heat is less dense than cold air so the warm air will rise. This rising motion creates a natural vacuum lowering the air pressure at the Earth’s surface.
How does the temperature of a tennis ball affect the bounce science fair project?
Tennis Science Fair Ideas
When it falls to the ground, the air within the ball expands and this causes the ball to bounce back. Changing the temperature of the ball affects the pressure of the air inside the ball and, in turn, the height to which it bounces.
How does temperature affect bounce?
This is because the gas molecules inside the ball expand as temperature increases . As the gas molecules expand, their energy increases and they bounce around faster inside the ball. That’s why higher pressure leads to a higher bounce of the ball. Likewise, a lower temperature will lead to a lower pressure.
What is the control variable in the bouncing ball experiment?
Dependent variable is the height that the ball bounces. Constants are the release height, the bouncing surface, the type and the size of the ball. Controlled variables are air temperature, air flow, air pressure where you perform your tests.
What affects the bounce of a ball?
The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
