"Caffeine may east post-workout pain"

New York Reuters health- That morning cup of coffee may be an antidote to post-exercise muscle soreness, if preliminary research is correct. IN a small study of female college students researchers found that a caffeine supplement seemed to lessen the familiar muscle pain that crops up the day after a particularly challenging workout. Known as delayed-onset muscle soreness or DOMS. The pain is common in the day or two after a workout that was more intense than normal. IN eccentric contraction the muscle produces a force while it's being lengthened. This happens when a person runs downhill, for example, or lowers a weight during a bicep curl. Exercised and researchers alike have tried many ways to prevent DOMS including over the counter painkillers, stretching and massage. But studies have found no cure all for the problem. In the current study published in the journal of pain researchers at the university of georgia in athens looked at the effects of a caffeine supplement on delayed muscle pain in nine young women. First, in a stimulated workout, the researchers used electrical stimulation to produce eccentric contractions in the women's thigh muscles-- enough to cause moderate day- after soreness.

Next, they repeated the procedure over the next two days, but on each day, the women took either a caffeine pill or placebo pill one hour before the muscle workout. Neither the women nor the researchers knew which pill was given on which day.

Overall, the women reported significantly less muscle soreness during the workout when they took caffeine instead of the placebo. The supplement had about the amount of caffeine found in two cups of coffee.

A. What is the research question/problem?

B. What is the hypothesis for the experiment?

C. Describe the control group.

D. Describe the experimental group.

E. What is the variable in the experiment?

F. List three flaws in the experimental design.

G. Redesign this experiment. In addiction to describing your experiment using words, help me visualize your experimental design by drawing a diagram and /or picture of how you would set up the experiment. be sure to include in your experiment description the following:

Variable, control group, and experimental group.

Please read and answer a-g thanks!!

its actually just like the others i found on here asked they are biology probability and scientific method questions. nevermind!

Answer 1

A. Aim:

The reaseach is particularly based on experimentally establishing the effect of caffeine and placebo on female body, post workout.

B. Hypothesis:

The effect of placebo is more effective than caffeine. As placebo contains almost two times the caffeine than coffee.

C. Control group:

This experiment as described, did not have any control group.

D. Experimental group:

The 9 women from a particular college group ,

Who were initially forced stimulated for muscle soreness and later continued for 2days.

This was accompanied with consumption of either caffeine or placebo.

E. Variable:

The variable of this group is amount of caffeine intake.

F. Flaws:

According to the experiment and personal opinion. The following can be considered as flaws-

1. The experiment could have been done with males.

As females might have menstrual cycle/syndrome, with affects the soreness and pain.

2. Researchers should have paid attention to consumption of placebo or caffeine during experimental study. For more reliable and specific result and conclusion.

3. The groups 9 females could have been seperated into 3 groups further. 1 group for control , 1 for just caffeine, 1 for just placebo.

G. Redesign:

The experiment canbe conducted with males of similar age group having similar characters.

The location can be taken as any certified gym, With dedicated males.

There 1 control group , and 2 experimental group can be setup for more accurate results.

Each experimental group can be given a different variable , viz placebo or caffeine.
