Physical Activity

I need some fun activity for about 100 people and I can’t have them leave there seats and move around the room. Something along the lines of the "make it rain" activity. Any ideas?

I love the rain thing. I came here to give you that answer, but you got me.
Uhh…
You could divide your room into two sections and have a red, white, and blue balloon assigned for each side. Tell the teens you are seeing if your teen group can take over the government contract for the US Mail service and you want to test out the spped of each side. Adults stand up front and hand the red ballon to a teen on the front row of each side. The teens on each side must bat the balloon all the way to the back of the room and then back up before you provide them with the white balloon. When they deliver that one up and back, send them the blue balloon.

This man is aged 36 years old and have an BMI of 35. I have to create a physical activity plan for him. This is just a school assessment. Ummm, what sport or physical activity should he do to lose weight and reduce his BMI to the healthy range over a long period of time? I had in mind, cardio kickboxing club 2-3 times a week, but is that realistic? can an obese survive or do kickboxing? please suggest more sports or pa.

Dear Luv,

One thing you need to understand is that you have to work hard if you want to change the shape of your body. That means a balance of medium-high intensity cardio exercise along with challenging strength training workouts.

For weight loss, you’ll need to get about 5 cardio workouts each week at a medium-high intensity for at least 30 minutes. If you’re a beginner, it’s best to start slow and work your way up but, if you’re in good condition and have no restrictions, challenging yourself with harder workouts is the best way to burn more calories. Interval training is a good choice because studies show you continue to burn calories even after you’ve stopped exercising.

In addition to your cardio workouts, you’ll need to lift weights for all your muscle groups at least 2 non-consecutive days a week. And, by lifting weights, that means using enough weight that you can ONLY complete the desired number of reps. For example, if you’re doing 12 bicep curls, you need to use enough weight that you can only do 12 bicep curls and not one more. Most people don’t lift enough weight to really challenge their muscles.

What you need to engage in is a well balanced all rounded diet with considerable physical exertion over a prolonged time period. Food can be broken down into 5 major groups. These groups are carbohydrates, proteins, fats, vitamins and minerals and water. The body needs varying amounts of these types of food so that the adequate amount of nutrients is supplied to the body. A well-balanced diet does not mean an equal amount of each type of food, as our body requires more of some nutrients than others.

Each type of food plays a significant role in our body but excesses or deficiencies of certain types of food can also harm the body and produce a negative impact on our health.

It is very important that we know how much of each type of food we are supposed to consume and that we eat in a sensible way. This means eating regular meals at "least" three times a day and drinking plenty of water, but what I would suggest is breaking it down to 5 smaller meals a day and having your last solid meal before 6pm after that you are only allowed to have pure low fat milk a mug or two would be a good idea to cut down on excessive cravings.

Hope this answers your question.

I find that when I exercise or even clean up my room, I feel kinda uplifted. So does some amount of physical activity help in alleviating minor forms of depression?

Yes it releases endorphins(sp) in the brain which have a similar affect as anti-depressants

On my wall, there were updates about my comment activity, Wall activity, etc. I wasn’t sure to which people would be able to view these, so I selected the option to hide it. However, now I want to unhide these updates (they appear as green speech bubbles). How do I do that?

i really depends on what you are trying to hide, and you arent very clear on that

Me and a friend are trying to lose weight and we have joined scottish slimmers so we have the dieting part down but we need an excersise or activity. We work six hours a day (9-3) and we only have sundays off. We have time after work but only a couple of hours so does anybody know a dast and affective excersise/activity?

No Time for Breakfast? – Make a superfoods smoothie with one of the green drink mixes. Add a scoop of protein powder, a scoop of superfoods greens powder and mix with ice, water and fruit for a delicious breakfast drink that will keep you satisfied for hours.

My human biology exam specification says :
"Describe how to carry out simple controlled experiments to illustrate how enzyme activity can be affected by changes in temperature"
What would they expect me to write?
As i read this http://www.123helpme.com/view.asp?id=122761 and it was a lot to remember just for one possible exam question? please help me , thank you
enzymes are made of proteins
proteins have a limited optimal range
if temps get out of range they unravel
since function is dependent on shape
they wouldn’t work any more
adjusting the temp slightly would lessen productivity
adjusting it maximum productivity would stop

Which of the following statements regarding the cascade of reactions leading to altered enzyme activity is false?

A.Glycogen synthase is inhibited in the cascade shown.
B.Phosphorylase kinase is inhibited in the cascade shown.
C.The binding of epinephrine results in the release of stored glucose in the cascade shown.
D.The binding of epinephrine results in the inhibition of glycogen synthesis in the cascade shown.
E.The cascade shown results in both the inhibition and activation of different enzymes.

the cascade is

We did an experiment on the effect of pH on enzyme activity. The enzyme we used is catalase from the liver. The problem is I didn’t get the results down. Our pH’s were 2, 7 and 10. I was just wondering what reaction you’d get. Which one would react the most or fastest?

Typically, most enzymes function best at a neutral pH.

hope this helps

A. Enzyme activity always increases with increasing temperature.
B. Higher temperatures typically in increase enzyme activity by lowering the activation energy of the reaction.
C. Higher temperatures increase enzyme activity by increasing the number of activated complexes that form each minute.
D. Low temperatures can denature enzymes by freezing them.
E. Enzymes are activated allosterically at certain temperatures, but excessive high heat may destroy them by denaturation.

E. higher temperatures are better, in general, unless the temp is so high that the protein is denatured.

Your Open Question: what is the effect of enzyme concentration on enzyme activity?

Explain how enzyme activity changes as enzyme concentration decreases, and discuss why this occurs (on a molecular level)

Enzymes are specific to the substrate that they will help break down. For each enzyme there will be one substrate to be acted upon. If you increase the amount of enzyme the amount of substrate breakdown will increase until it is used up. If you decrease the amount of enzyme the rate of reaction will slow until the enzymes help break down all the substrate.
