<p> The purpose of this study was to investigate the effects of a high intensity interval training program (HIIT) using the upper extremities on peak oxygen uptake (VO_2peak), peak heart rate (HR_peak), total time-to-fatigue (TTF), peak power output (PPO), rating of perceived exertion (RPE), and blood lactate concentrations (bLa). Results showed significant (p &le; 0.05) improvements by the HIIT group in VO_2peak, HR_peak, PPO, and TTF when compared to a continuous training (CT) group. </p><p> Results of this study suggest that upper extremity HIIT appears to produce greater improvements in several physiological outcome measures when compared to CT and may be an effective way to improve cardiopulmonary fitness. Furthermore, a HIIT program using the upper extremities as little as 2 days per week appears to be a viable way to improve factors that contribute to cardiopulmonary fitness, muscular fitness, and performance, while being an efficient use of time.</p>

<p> The purpose of this study was to measure power output of the vertical jump after a static stretch versus post-activation potentiation without stretching. Six males (24.8 &plusmn; 4.3 years old) were tested using three different protocols; non-stretch (NS) with a 5RM back squat test, static stretch (SS), and post-activation potentiation (PAP). Mean and peak power output (W) were calculated using the Lewis, Sayers, Harman, and Johnson &amp; Bahamonde formulas. An increase in jump height and power was observed in both the SS and PAP (1685.0 &plusmn; 260.4 W and 1713. 2 &plusmn; 257.4 W) protocols from the baseline NS (1647.2 &plusmn; 267.4 W) protocol. Stretch-induced impairments were not observed in the current study. PAP was shown to increase power output from baseline testing (p= 0.0001). It can be concluded that SS and PAP have a positive affect on athletic performance and should be studied further.</p>

<p> This study compared the level of agreement and interrater reliability between novice and expert FMS evaluators from observing only the deep squat test. Sixty healthy subjects (36 females and 24 males) between the ages of 18-35 years performed the deep squat test and were scored by 20 FMS raters (experience levels ranging from five months to five years). All subjects who scored a 0 were eliminated from this study. Each of the subjects was video taped from the sagittal and frontal view. Data was determined using a Chi square test (p &le; 0.05) and a Kappa statistic. The interrater reliability was considered less than chance agreement with a Kappa value = -0.009. The Chi-Square value resulted in a p-value = 0.865, which is greater than the probability of p = 0.05. Results showed that there were no significant differences between the novice and expert FMS raters on the ability to agree 50% or more of the time on the deep squat test. The interrater reliability for the deep squat test resulted to be poor reliability within the two groups of FMS raters. </p>

We studied the accommodation of the increased pulmonary blood flow in the transition from rest through two successive levels of exercise in 19 awake mongrel dogs. We used the single bolus multiple indicator dilution technique with markers of the pulmonary vascular surface area and studied their behaviour at exercise. In a first set of experiments (n = 9) ($ sp3$H) norepinephrine served as the vascular surface area tracer while ($ sp3$H) benzoyl-Phe-Gly-Pro (($ sp3$H) BPGP), an inactive angiotensin-converting enzyme substrate was utilized in another (n = 10). Three other tracers were also injected with the surface markers: two vascular space markers, ($ sp{51}$Cr) erythrocytes and ($ sp{125}$I) albumin, and a water space tracer, ($ sp{14}$C) 1,8-octanediol. The mixture was injected into the pulmonary circulation and timed outflow samples were collected in the ascending aorta to obtain dilution curves. With exercise, the increase in pulmonary blood flow was accompanied by a linear increase in oxygen consumption. The range of blood flow achieved varied from 41 ml/s to 457 ml/s. The central blood volume as measured from the intravascular references increased linearly with flow. The tracer accessible extravascular lung water increased with flow and rapidly approached a maximal asymptotic proportion representing 75% of the postmortem lung weight. The ratio of the dilutional estimates of the extravascular lung water to that measured gravimetrically also increased in a similar fashion to reach an asymptotic proportion of close to 100%. These values were attained for moderate values of blood flow and did not increase further with higher blood flows. Tracer norepinephrine extractions at rest and at the two levels of exercise were 17% $ pm$ 1.2, 14% $ pm$ 0.8 and 15% $ pm$ 0.8 (SE) respectively. Using the Crone approximation we computed the permeability surface area product (PS) for norepinephrine. The PS product increased linearly with flow. Similarly, the proportional ($
