ABSTRACTAn intervention trial with regular physical activity was carried out to test the hypothesis that walking speed is related to the level of cardiovascular fitness (maximal oxygen uptake). Earlier research has demonstrated that when VO2 max is held constant in a multiple regression analysis the association between walking speed and age (29–65 y) is eliminated. To describe the association between self-selected speeds of walking, and level of cardiovascular fitness, 63 men age 60 to 65 were studied before and after a 1 year program of exercise training. VO2 max was determined on a motor driven treadmill. A test of self-selected walking pace was administered over a 240 m indoor course. The men were asked to walk at 3 paces considered by the subjects to be rather slow, normal, and fast, respectively. They were randomly assigned with stratification for white and blue collar occupation to a program of exercise training (n = 33) or control (n = 27). The training program consisted of walking or jogging for 30 min three times per week for one year. After the training program the exercise group increased their VO2 max (9.5%) and their normal walking speed (1.29 to 1.43 m.s−1) significantly compared to the controls. A program of exercise endurance training will result in an increase in the speed of self-selected pace.

Sport-climbing popularity increased intensely over the past years. Particularly, children’s and adolescents’ interest therein is constantly growing. Despite a large effort in preventing injuries and muscle overloads, a fine-tuned training for each sensitive phase of child development is still needed. The objective of the study was to evaluate an innovative training program aimed at the preservation of joint mobility during the developmental age. This article relies on the results of a steady training program allowing to retain joints integrity among the practice of sport climbing in children. Joint mobility changes have been monitored before and after a one-year training program in fifteen subjects aged between 8 and 18 years. Subjects were divided into three groups depending on age (Turgor Secundus, Proceritas Secunda and Turgor Tertius). The motor tests administered were the sit-and-reach test, coxo-femoral mobility test and scapula–humeral mobility test. Our results showed that one-year training improved joint mobility at each analyzed phase, suggesting that this training program could improve mobility and flexibility. Given the importance of joint mobility preservation for discipline-related injuries prevention and eventually recovering, it is essential to provide a specific training program as a route to approach sport climbing, and even more importantly, at an early age. This work represents a preliminary study in order to demonstrate both efficacy on the joint mobility and the requirement of our playful work to support the global sport-climbing workout.

Nine elite male junior weightlifters (mean age 17.6 ± 0.3 yrs) performed weightlifting tests before (Test 1) and after (Test 2) 1 week of increased training volume (overreaching) and repeated the protocol after 1 year of their training program. Strength increased by Year 2 (p < 0.05) but did not change during either week of increased training volume. The 1-week overreaching stimulus resulted in attenuated exercise-induced testosterone concentrations during Year 1, but augmented exercise-induced testosterone concentrations during Year 2. Testosterone concentrations at 7 a.m. decreased for only Year 1. For both years, the 1-week overreaching stimulus increased Cortisol at 7 a.m., indicative of the increased training volumes. Testosterone/Cortisol was not affected by increased training volume for either year. One year of chronic weightlifting and prior exposure to the overreaching stimulus appears to decrease the detrimental effects of stressful training on the endocrine system.

The aims of the present study are twofold: 1) to investigate whether heart rate recovery (HRR) after a cycle ergometry test is affected by exercise training and 2) to test the ability of HRR to replicate the baroreflex sensitivity (BRS) changes that occur in response to an exercise training program in coronary artery patients. We randomized 82 coronary artery patients undergoing a residential cardiac rehabilitation program to an exercise training group (TR; n = 43) and an untrained group (UTR; n = 39). All of the patients underwent an exercise test before and after the rehabilitation program. HRR was recorded at the end of the 1st and 2nd min after exercise. BRS was determined at rest before and after treatment. HRR after the 2nd min was significantly improved in TR patients (−21.4 ± 0.9 beats/min) compared with UTR patients (−17.8 ± 1.2 beats/min) at the end of the training program. Improvement in HRR paralleled that in BRS in TR patients (from 3.2 ± 0.3 to 5.3 ± 0.8 ms/mmHg; P < 0.001), whereas no significant change was evident in UTR patients (from 3.5 ± 0 to 4.0 ± 0.4 ms/mmHg; P = 0.230). Our data show that HRR in the 2nd min after the cessation of a cycle ergometer exercise test increased in coronary artery patients after an exercise training period. This result confirms the positive effect induced by exercise training on HRR and extends the conclusions of previous studies to different modalities of exercise (i.e., cycle ergometer). HRR might provide an additional simple marker of the effectiveness of physical training programs in cardiac patients.

Abstract Introduction Vascular endothelial dysfunction is an underlying pathophysiological feature of chronic heart failure (CHF). Exercise has been shown to stimulate the mobilization of endothelial progenitor cells (EPC) in healthy populations. EPC contribute to the regeneration of the inflammatory endothelium and promote neovascularization. Purpose The purpose of the present study was to investigate the mobilization of EPC between CHF patients with different severity after a 36-session exercise training program. Methods Thirty eight consecutive patients (32 ♂, 6 ♀) with stable CHF [mean±SD, age (years): 56±10, EF (%): 32±9, peak VO2 (ml/kg/min): 18.1±4.1] enrolled a 36-session exercise training program. All patients underwent a symptom limited maximal cardiopulmonary exercise testing (CPET) on a cycle ergometer before and after the training program. Venous blood was sampled before and after each CPET. Five endothelial circulating populations were quantified by flow cytometry (Table 1). Patients were divided in severity groups according to the median values of peak VO2, predicted peak VO2, VE/VCO2 slope and EF. EPC values are expressed as “cells/million enucleated cells” in medians (25th, 75th percentiles). Results In all patients, rehabilitation showed a statistical significant effect as well as a significant acute effect in all endothelial circulating populations (p<0.001). Although there was statistical significant mobilization of endothelial circulating populations within each severity group (groups separated by peak VO2), no differences were observed between groups (p>0.05, Table 1). Similar results were also shown for the rest of CPET parameters and EF.

Conclusion A 36-session training program stimulates the long term mobilization of EPC in CHF patients. This mobilization seems to be similar in all patients irrespective of their severity. The clinical relevance of these findings and the potential mechanisms need further investigation.

Introduction: The purpose of this study was to investigate the effects of shortened-length versus through-range exercise training on upper quarter posture in primary school students with Forward Head Posture (FHP). Materials and Methods: Sixty pain-free participants with FHP were randomly allocated to one of three groups; shortened-length training (n=20), through-range training (n=20), and no- treatment control group (n=20). The shortened-length and through-range groups participated in training programs 3 times per week for 8 weeks. Upper quarter postures, including Craniovertebral Angle (CVA), Shoulder Angle (SA), Cranial Angle (CA), and thoracic kyphosis were measured by photogrammetry before and after the training. The confidence level was set at 95% (P<0.05). Results: After training, both exercise groups showed significant changes in CVA (P=0.001), SA (P=0.001), CA (P=0.001), and thoracic kyphosis (P=0.001) compared to the control group. Furthermore, CVA changed more in the shortened-length exercise group compared to the through-range exercise group (P=0.003) (effect size= 0.446). Conclusion: Both through-range and shortened-length exercises altered upper quarter alignment. The shortened-length training resulted in a larger change in CVA. These changes were small, and more studies are needed to investigate the effects of such training programs among people with pain.
