Abstract
Context: A comparison of single and dual heating on acute gains in hamstring extensibility. Objective: To determine if active warm-up in conjunction with warm water immersion will have a greater effect on hamstring extensibility than active warm-up on land. Design: Crossover Setting: Research laboratory. Participants: Eighteen physically active males (20.4± 1.8 yrs, ht= 196. 2± 7.1cm, mass= 90.5 ± 22.5kg) experiencing limited hamstring extensibility and no low back or leg injury within 6 months prior to collection, or heat related illnesses that required medical attention. IRB approval was given. Intervention: During three sessions participants were measured before and after one of the three IO-minute warm-up protocols according to a Balance Latin Square treatment order. One treatment considered of resting supine (Rest), while the others included a step-up exercise at an intensity between 60%-80%s of their Karvonen calculated heart rate, with only one of these being performed in a waist deep 40.5°C warm water immersion (On-Land & Water, respectively. Main Outcome Measure: Hamstring extensibility gain quantified by the difference between the highest of three Active Assisted Straight Leg Raise angles of inclination pre and post measures to the nearest .1 °. Repeated ANOVAs and Tukey-Kramer MC test were used. Alpha was set a priori at .05. Results: Each treatment caused different gains (F2,34= 4.46, P = .02). Specifically, the Rest gains (1.9 ± 2.6°) were 3.1 ° less than the Water (5.0 ± 4.4°), with the On-Land (2.7 ± 4.0°) gains not being significantly different from the others. (MSE=l0.98 Critical Value=3.47). Conclusion: Warming-up in a warm water immersion increases acute hamstring extensibility gains.
