Your assignment!

[compleks]

I need help finding studies, or reputable articles.

I need information on the effects of basic joint rotations (arm windmills etc...). Specifically, I would like information / studies on the effects of basic knee bends as a warm up activity (simple flexion and extension of the knee joint, similar to a squat. And circling movements if possible.)

I basically need proven information on their effectiveness as a warm up activity, in terms of blood flow, lubrication of the joints, and motor control, etc...

I just need to know that I am right about something, and can prove a certain person wrong.

Thankyou, let the search begin!

These are some references could be interesting, but I didn't read them

The effect of static and dynamic stretching exercises on the maximal isokinetic strength of the knee extensors and flexors. By: Papadopoulos, G.; Siatras, Th.; Kellis, S.. Isokinetics & Exercise Science, 2005, Vol. 13 Issue 4, p285-291, 7p, 2 graphs; (AN 19251243)

WARM-UP PROGRAMS. By: Tindale, Rabina. Emergency Nurse, Mar2005, Vol. 12 Issue 10, p6-6, 1/6p, 1c; (AN 16387966)

{This study aimed to investigate the effect of structured warm-up programmes on reducing the incidence of knee and ankle injuries in young people participating in sports such as football, basketball or handball.

The authors conducted a randomised controlled trial involving 16- and 17-year-olds from 123 clubs who either did, or did not, take part in a specially devised warm-up programme involving four different sets of exercises of increasing difficulty.

The main focus of the programme was to improve awareness and control of knees and ankles during standing, running, jumping and landing.

Coaches were asked to use the programme at the beginning of every training session for 15 consecutive sessions and then once a week for the rest of the season.

Results showed that the clubs using the training exercises had a significantly lower incidence of injuries than those in the control group. The authors argue that the sample size is sufficient to show that the incidence of acute knee and ankle injuries can be halved and that the incidence of severe injuries can be reduced even more.

They suggest that health professionals work with sports clubs to develop exercise programmes to prevent such injuries especially among weekend recreational athletes.}

I'll be back later

How about finding some studies against their argument in conjunction with studies for your's. What are they claiming?

I suggest these links for your search (just in case you don't know them already)

I didn't find anything specific about joint rotations but didn't have much time.
