the effect on nasal resistance of an external nasal splint during isometric and Isotonic Exercise
Clinical Otolaryngology, 1999Co-Authors: A D WildeAbstract:The now commonplace wearing of external nasal splints by sportsmen and athletes has never been scientifically evaluated. The present study looks into the effect of both isometric and Isotonic Exercise on nasal resistance and examines if this is altered by the wearing of an external nasal splint. Twenty subjects who did not suffer from rhinitis were tested. Nasal resistance measurements were recorded using an anterior rhinomanometer before and after Exercise, with and without an external nasal splint. Pulse and blood pressure were measured using a Criticare Inc. model 508 physiological monitor before and after Exercise. Significant changes were observed in pulse (P < 0.001) and both systolic (P < 0.002) and diastolic (P < 0.001) blood pressure in response to Isotonic Exercise and pulse (P < 0.0001) and diastolic blood pressure (P < 0.0006) in isometric Exercise. Significant differences were seen in nasal resistance when the splint was applied before (P < 0.001) and after Exercise in both groups (P < 0.003). No significant difference was observed between the post-Isotonic Exercise groups with and without the splint (P= 0.167) but significant differences were seen in the isometric group (P < 0.0001). External nasal splints decrease nasal resistance at rest but are of little proven value when performing Isotonic Exercise however significantly reduce nasal resistance during isometric Exercise.

effect on nasal resistance of an external nasal splint and Isotonic Exercise
British Journal of Sports Medicine, 1999Co-Authors: A D WildeAbstract:OBJECTIVES: The now commonplace wearing of external nasal splints by sportsmen and athletes has never been scientifically evaluated.

METHODS: Twenty subjects not suffering from rhinitis were tested. Nasal resistance measurements were recorded using an anterior rhinomanometer before and after Isotonic Exercise with and without an external nasal splint. Pulse and blood pressure were measured before and after Exercise. RESULTS: Significant changes were observed in pulse (p < 0.001) and both systolic (p < 0.002) and diastolic (p < 0.001) blood pressure in response to Exercise. Significant differences were seen in nasal resistance when the splint was applied (p < 0.001) and after Exercise (p < 0.003). No significant difference was observed after Exercise when the splint was worn (p = 0.167). CONCLUSIONS: External nasal splints decrease nasal resistance at rest but are of little value during Isotonic Exercise.

hemodynamic effects of supervised calf muscle Exercise in patients with venous leg ulceration a prospective controlled study
Archives of Surgery, 2001Co-Authors: Konstantinos T DelisAbstract:Hypothesis Because more than two thirds of patients with venous ulcer have an impaired calf muscle pump, enhancement of its ejecting ability with physical training may generate an improved hemodynamic milieu sufficient to promoting ulcer healing. This study evaluated the effects of short-term supervised calf Exercise on calf muscle pump function and venous hemodynamics in limbs with venous ulceration. Design Prospective controlled study. Settings University-associated tertiary care hospital. Patients The study consisted of 2 groups. An Exercise group comprised 10 patients (median age, 72 years) receiving supervised Isotonic calf muscle Exercise for 7 consecutive days. A control group comprised 11 patients matched with those in the Exercise group for age, sex, ulcer size, and ulcer duration (all,P>.09). Patients in both groups had perimalleolar venous leg ulcers, impaired calf muscle function (ejection fraction, Interventions After providing a complete clinical history, both groups underwent a physical examination, venous duplex scanning, and air plethysmography. The venous filling index, venous volume, residual venous volume, and residual volume fraction of the calf on standing were measured plethysmographically at baseline and on day 8, in addition to calf muscle endurance as determined by the maximal number of plantar flexions performed against a fixed 4-kg resistance during 6 minutes (1 flexion/s). Operators were blinded to the subject's group. Exercise in the first group entailed consecutive active plantar flexions using a standardized 4-kg resistance pedal ergometer. Subjects daily completed 3 sets of flexions of 6 minutes each. All patients had short-stretched compression bandaging. Main Outcome Measures The ejected venous volume and ejection fraction were evaluated in both groups at baseline and on day 8. Results Both groups had a similar hemodynamic performance at baseline for all the variables evaluated (P>.10). After 7 days of Exercise, patients in the Exercise group improved their ejected venous volume by 67.5%, ejection fraction by 62.5%, residual venous volume by 25% (all 3,P= .006), and their residual volume fraction by 28.6% (P= .008). Changes in the control group within the same period were small (all,P>.10). By day 8, the Exercise group had a significantly better ejected venous volume (P .50) in either study group. Calf muscular endurance in the Exercise group increased 135%, from a median 153 plantar flexions at baseline to 360 on day 7 (P Conclusions By increasing the muscular endurance, efficacy, and power of the calf muscle, Isotonic Exercise improves its ejecting ability and the global hemodynamic status in limbs with venous ulceration. Prospective evaluations of the clinical effects of calf muscle pump strengthening for the treatment of venous leg ulceration are indicated by the results of this study.

isometric Exercise for acute pain relief is it relevant in tendinopathy management
British Journal of Sports Medicine, 2019Co-Authors: Karin Gravare Silbernagel, Bill Vicenzino, Michael Skovdal Rathleff, Kristian ThorborgAbstract:Isometric Exercise as an initial treatment and in-season pain management for tendinopathies has become the latest trend, yet clear evidence in support of this approach is lacking. This new approach is based on a small cross-over study (n=6)1 and a small randomised control trial (n=20)2 comparing isometric and Isotonic muscle contraction by Dr Ebonie Rio and colleagues. They reported substantial, acute effects of isometric Exercise on pain in patients with patellar tendinopathy, which was greater than seen with Isotonic Exercise. While the pain relieving response of isometrics in the first trial1 was dramatic and homogenic, the pain relief response of the second trial2 was much more heterogenic. Based on these results an isometric management approach was quickly extrapolated to other tendons, as evinced in a popular recently updated sports medicine textbook.3 We contend that three important questions need to be answered before isometric Exercise is widely adopted as standard valid first step in tendinopathy management.

the effect of isometric Exercise on pain in individuals with plantar fasciopathy a randomized crossover trial
Scandinavian Journal of Medicine & Science in Sports, 2018Co-Authors: Henrik Riel, Bill Vicenzino, Martin Bach Jensen, Jens Lykkegaard Olesen, Sinead Holden, Michael Skovdal RathleffAbstract:Isometric Exercise is commonly recommended for immediate pain relief in individuals suffering from lower limb tendinopathies, despite the limited evidence supporting its analgesic effect. Due to the similarities between plantar fasciopathy and tendinopathies, the aim of this trial was to investigate the acute effect of isometric Exercise on pain, compared to Isotonic Exercise, or walking, in individuals with plantar fasciopathy. We recruited 20 individuals with plantar fasciopathy for this prospectively-registered, participant-blinded, randomized, superiority crossover trial (ClinicalTrials.gov: NCT03264729). Participants attended three Exercise sessions (isometric, Isotonic, or walking) in a randomized order, within a 2-week period. Both isometric and Isotonic Exercises were performed standing with the forefoot on a step bench, while walking was performed barefoot. The primary outcome was pain (measured on a 0-100-mm VAS) during a pain-aggravating activity. Secondary outcomes included pressure pain threshold (PPT) under the heel, and plantar fascia thickness (PFT). All outcomes were measured before and after each Exercise session. There were no significant differences between the three Exercises on pain (P = 0.753), PPTs (P = 0.837), or PFT (P = 0.718). Further, there was no change in pain from before to after any of the Exercises (isometric Exercise 2.7 mm [95% CI: -12.2; 6.8], Isotonic Exercise -3.4 mm [95% CI: -5.0; 11.8], or walking 1.6 mm [95% CI: -16.1; 12.9]). Contrary to expectations, isometric Exercise was no better than Isotonic Exercise or walking at reducing pain in individuals with plantar fasciopathy. None of the Exercises induced any systematic analgesic effect.
