The Effect Of Cold-Water Immersion On Running Mechanics, Lucas M. Dibenedetto, Kristyne Wiegand, Julia Freedman Silvernail

International Journal of Exercise Science

International Journal of Exercise Science 12(1): 547-555, 2019. Cryotherapy is a common treatment used by athletes for rehabilitating acute injuries of a joint or muscle in order to accelerate recovery time and promptly return to play. Therefore, the potential effects of cryotherapy on performance and injury risk should be considered. The purpose of the current study was to investigate the effects of cold-water immersion on running mechanics. Fifteen healthy male and female participants (24.6 ± 5.74 years, 166.37 ± 7.67 cm, 71.72 ± 17.7 kg, 27.47 ± 7.55% body fat) were recruited for the study. Participants completed 10 running trials …

Adrenergic Control Of The Cutaneous Circulation During Cryotherapy, Kevin M. Christmas

International Journal of Exercise Science: Conference Proceedings

Cryotherapy application is a widely clinically used therapeutic technique using ice or cold water applied to the skin surface to reduce local blood flow. While beneficial, cryotherapy treatment does have the potential to induce some detrimental physiological side effects. For example, cryotherapy treatment induces pronounced tissue ischemia that is sustained for hours even during a post-treatment rewarming period. PURPOSE: To investigate the role of adrenergic receptor activation on cutaneous blood flow during 30 min of cryotherapy as well as during the subsequent 1 hr of passive rewarming. We hypothesized that adrenergic-mediated vasoconstriction is involved in pronounced and sustained cutaneous vasoconstriction …

The Effects Of Cold Water Immersion On Fractioned Response Time, Patricia Jean Romney

Theses and Dissertations

Objectives: Quantify the effects of cold water immersion of the ankle on fractioned response time of the dominant lower limb. Design and Setting: A 2x2x5x5 crossover design with repeated measures on time and treatment directed data collection. The independent variables were gender, treatment, time (pretreatment, and post 15 seconds, 3 minutes 6 minutes and 9 minutes) and trial (5 trials for each time group). Response time (Tresp), reaction time (Treac), trial and surface temperature were measurement variables. Subjects: Thirty-six subjects, 18 females and 18 males were recruited from a physically active volunteer college student population. Measurements: Fractioned response time was …

Motor Function Responses To Induced Pain And Cryotherapy, Blaine Cletus Long

Theses and Dissertations

Objective: Establish and validate an experimental pain model that will create pain for at least 20-minutes and then use the model to determine if: 1) cryotherapy decreases experimentally induced pain, 2) experimentally induced pain contributes to arthrogenic muscle inhibition, and 3) cold application influences pain or arthrogenic muscle inhibition. To answer these questions we conducted two experiments, the results of which are presented in two manuscripts. Methods: Seventy (n = 30 for experiment I and n = 40 for experiment II), physically active healthy male subjects participated. Interventions: Independent variables used for experiment I were condition (5% hypertonic saline infusion/cryotherapy, …

Dabbing The Skin Surface Dry During Ice Massage Augments Rate Of Temperature Drop, Amrik S. Sidhu, Gary Lentell, Robert Pettitt

International Journal of Exercise Science

While ice massage (IM) is a rapid cooling technique used to facilitate therapeutic movements in the rehabilitation process, evidence of its efficacy over alternative therapeutic protocols is scarce. We determined whether dabbing the skin surface dry during a standard IM treatment would lead to greater rate of skin temperature reduction in comparison to without dabbing; and whether dabbing the skin would lead to an acute change in flexibility. Sixteen healthy volunteers received a “dabbing” and “non-dabbing” 7-minute IM treatment over the surface of each triceps surae muscle. Minute-by-minute temperature change in skin surface was evaluated using an infrared thermometer. Active …

Effects Of Ankle Joint Cooling On Peroneal Short Latency Response, J. Ty Hopkins, Iain Hunter, Todd Mcloda

Faculty Publications

While cryotherapy has direct physiological effects on contractile tissues, the extent to which joint cooling affects the neuromuscular system is not well understood. The purpose of the study was to detect changes in ankle dynamic restraint (peroneal short latency response and muscle activity amplitude) during inversion perturbation following ankle joint cryotherapy. A 2x3 factorial design was used to compare reaction time and EMG amplitude data of treatment conditions (cryotherapy and control) across time (pre-treatment, post-treatment, and 30 min post-treatment). Thirteen healthy volunteers (age 23 ± 4 yrs, ht 1.76 ± 0.09 m, mass 78.8 ± 16.6 kg), with no history …

The Effects Of Three Different Ice Bath Immersion Times On Numbness (Sensation Of Pressure), Surface Temperature, And Perceived Pain, Norma E. Johnson

Theses and Dissertations

Objectives: Determine if numbness differs in magnitude and duration between 10-, 15-, and 20-min ice bath immersions, when temperature was held constant. Design: Dependant variables; sensation of pressure (g), perceived pain (cm), and skin temperature (º C). A repeated measures 3 X 19 factorial guided this study. Conditions were 10-, 15-, and 20-min ice bath immersions. Measurement times were before immersion, 1, 3, 5, 7, 9, 10, 11, 13, 15, 17, 19, and 20 min immersion, and 1.5, 3, 5, 7, 9 and 11 min postimmersion. Subjects: Eighteen college-aged volunteers. Measurements: Subjects participated in three ice bath immersions (10, 15, …
