Extend-A-Cool Test Results

Various in vivo tests were conducted to determine the efficacy of Extend-A-Cool according to real-life application situations.
The following presents the findings from these three tests:

• Test 1. Application on Resting Race Horses
• Test 2. Application Following Race Horse Training
• Test 3. Application Following Pleasure Horse Riding

Test 1. Extend-A-Cool & Resting Race Horses

Methodology

A cooling sheet was applied to resting racehorses to measure the cooling action when body heat was normal. This was conducted in order to see how body heat might impact the longevity of cooling action. The sample sheet was stored at room temperature.
An Extend-A-Cool sheet and wrap were applied to the right lower leg, with the left leg uncovered (control). A temperature sensor placed between the right leg surface and Extend-A-Cool captured temperature changes at one-minute intervals for approximately eight hours.

Test Results

• As shown in figure 1, the area where Extend-A-Cool was applied, cooled rapidly by approximately 6ºF initially or two hours.
• For four hours thereafter, the temperature difference still averaged 4ºF lower.
• When the Extend-A-Cool was removed, no hair
• was lost.

Test 2. Application Following Race Horse Training

Methodology

In this test, racehorses were trained under normal conditions and then cooled down for 30-minutes, followed by leg washing for ten-minutes. An Extend-A-Cool sheet and wrap were applied to the calf and shin of the front leg, and a temperature sensor was placed between the leg's surface and the sample. The left leg (control) had a temperature sensor wrapped by an Extend-A-Cool wrap only. Sensors were connected to a recorder attached to the horse's mane, and measurements were taken for two hours in one-minute intervals.

Test Results

• As shown in figure 2, immediately after the sample was applied to the area, a temperature difference of about 5ºF was maintained for the full two hours.

Test 3. Application Following Pleasure Horse Riding

Methodology

In this test, a pleasure horse was taken for a brief ride. Five minutes later, an Extend-A-Cool sheet and wrap were applied to the calf and shin of the right leg, with temperature sensors attached as in prior tests. An Extend-A-Cool wrap was placed on the left leg as a control, and temperatures of both legs were measured for 2.5 hours at one-minute intervals.

Test Results

• As shown in figure 3, immediately after the sample was applied to the area, a temperature difference of approximately 8ºF was measured for the first half-hour.
• For the remainder of the test, temperature differences were 6ºF or more.

Additional Technical Data

Extend-A-Cool may not be enough for more serious cases of tendonitis where hematomas exist; however, when used in conjunction with ice massages and other regimens established by the equine medical community, Extend-A-Cool can extend cooling therapy up to 6-hours for each transdermal sheet used.

• Water content of each Extend- A-Cool sheet is 59 grams, or 73.2% of the total weight of the 80 gram sheet.
• Extend-A-Cool sheets work by heat vaporization of water content.
• Refrigerating Extend-A-Cool will increase it's cooling capacity for the first ten minutes; however temperature changes after that point equalize with the research results obtained in non- refrigerated tests.

• When Extend-A-Cool samples stored at room temperature are applied, the area cools rapidly by approximately 6ºF. A temperature difference of approximately 5ºF or more was maintained for four hours. For two hours thereafter, cooling fell off by approximately 2ºF.
