Background: The effectiveness of cardiovascular screening in minimising the risk of athletic field deaths in master athletes is not known. Objective: To evaluate the prevalence and clinical significance of ST segment depression during a stress test in asymptomatic apparently healthy elderly athletes. Methods: A total of 113 male subjects aged over 60 were studied (79 trained and 34 sedentary); 88 of them (62 trained and 26 sedentary) were followed up for four years (mean 2.16 years for athletes, 1.26 years for sedentary subjects), with a resting 12 lead electrocardiogram (ECG), symptom limited exercise ECG on a cycle ergometer, echocardiography, and 24 hour ECG Holter monitoring. Results: A significant ST segment depression at peak exercise was detected in one athlete at the first evaluation. A further case was seen during the follow up period in a previously “negative” athlete. Both were asymptomatic, and single photon emission tomography and/or stress echocardiography were negative for myocardial ischaemia. The athletes remained symptom-free during the period of the study. One athlete died during the follow up for coronary artery disease: he showed polymorphous ventricular tachycardia during both the exercise test and Holter monitoring, but no significant ST segment depression. Conclusions: The finding of false positive ST segment depression in elderly athletes, although still not fully understood, may be related to the physiological cardiac remodelling induced by regular training. Thus athletes with exercise induced ST segment depression, with no associated symptoms and/or complex ventricular arrhythmias, and no adverse findings at second level cardiological testing, should be considered free from coronary disease and safe to continue athletic training.

Objective: Regular physical activity is associated with a reduction of cardiovascular morbidity and mortality; however, evidence of unfortunate cardiovascular events accompanying elite sport involvement continues to accumulate. To date, no information is available on possible peculiarities of the cardiovascular risk profile in athletes. Design: The aim of this study was to evaluate plasma homocysteine levels in a group of athletes and to search for relationship with vitamin status and other metabolic variables in order to confirm the existence of a “sport-related hyperhomocysteinaemia” and to explain its clinical significance. The study population was composed of 82 athletes (59 male and 23 female) practising different sports and 70 healthy age-matched subjects (40 male and 30 female) as a control group. Besides the general clinical and analytical determinations, the assessed variables included homocysteine, folate, vitamin B12, total and high-density lipoprotein (HDL) cholesterol, lactate dehydrogenase (LDH), creatine kinase (CPK) and interleukin-6 (IL-6). Results: The prevalence of hyperhomocysteinaemia (>15 μmol/l) in athletes and controls was 47% and 15%, respectively. No correlation was found between homocysteine and any of the other investigated variables, in particular plasma folate, blood pressure, LDH, CPK, total and HDL cholesterol and IL-6. Conclusion: The results of this study confirm the existence of a sport-related hyperhomocysteinaemia which appears linked neither to the same variables found in the general population, nor to specific training-related variables. We suggest that it would represent an adaptation to training but the possibility of a secondary vascular damage cannot be excluded.

Effects of physical activity in Parkinson's disease: A new tool for rehabilitation

Paolo Borrione; Eliana Tranchita; Pierpaolo Sansone; Attilio Parisi

Parkinsons disease (PD) is a common neurodegenerative disease characterized by bradykinesia, tremor, rigidity, and postural instability. Motor disorders are composite and combined, adversely affecting the patients health. Tremor and rigidity are correlated with worsening manual dexterity as well as postural changes such as akinesia and camptocormia. Moreover, gait alteration as well as postural instability, with consequent impairment in balance, increase the risk of falls. It is well known that these symptoms respond poorly to pharmacologic therapy in PD patients. Physical therapy is the most effective non-pharmacological aid to PD patients. Available data in the literature indicate that any rehabilitation protocol has to focus on: cognitive movement strategies, cueing strategies, and improved physical capacity and balance. Different training programs for PD patients have been designed and evaluated but only specific training strategies, tailored and individualized for each patient, may produce improvements in gait speed and stride length, decrease motor and balance symptoms and improve quality of life. Furthermore, aerobic training may improve muscle trophism, strength and mobility. It seems reasonable to state that tailored physical activity is a valid tool to be included in the therapeutic program of PD patients, considering that this approach may ameliorate the symptoms as well as the overall physical incapacity, reduce the risk of falls and injuries, and ultimately improve quality of life.

We recently demonstrated that low frequency, moderate intensity, explosive-type resistance training (EMRT) is highly beneficial in elderly subjects towards muscle strength and power, with a systemic adaptive response of anti-oxidant and stress-induced markers. In the present study, we aimed to evaluate the impact of EMRT on oxidative stress biomarkers induced in old people (70–75 years) by a single bout of acute, intense exercise. Sixteen subjects randomly assigned to either a control, not exercising group (n=8) or a trained group performing EMRT protocol for 12-weeks (n=8), were submitted to a graded maximal exercise stress test (GXT) at baseline and after the 12-weeks of EMRT protocol, with blood samples collected before, immediately after, 1 and 24 h post-GXT test. Blood glutathione (GSH, GSSG, GSH/GSSG), plasma malonaldehyde (MDA), protein carbonyls and creatine kinase (CK) levels, as well as PBMCs cellular damage (Comet assay, apoptosis) and stress–protein response (Hsp70 and Hsp27 expression) were evaluated. The use of multiple biomarkers allowed us to confirm that EMRT per se neither affected redox homeostasis nor induced any cellular and oxidative damage. Following the GXT, the EMRT group displayed a higher GSH/GSSG ratio and a less pronounced increase in MDA, protein carbonyls and CK levels compared to control group. Moreover, we found that Hsp70 and Hsp27 proteins were induced after GXT only in EMRT group, while any significant modification within 24 h was detected in untrained group. Apoptosis rates and DNA damage did not show any significant variation in relation to EMRT and/or GXT. In conclusion, the adherence to an EMRT protocol is able to induce a cellular adaptation allowing healthy elderly trained subjects to cope with the oxidative stress induced by an acute exercise more effectively than the aged-matched sedentary subjects.

Objective T wave inversion (TWI) has been associated with cardiomyopathies. The hypothesis of this study was that TWI has relevant clinical significance in peri-pubertal athletes. Methods Consecutive male soccer players, aged 8–18 years, undergoing preparticipation screening between January 2008 and March 2009 were enrolled. Medical and family histories were collected; physical examinations, 12-lead ECGs and transthoracic echocardiogram (TTE) were performed. TWI was categorised by ECG lead (anterior (V1–V3), extended anterior (V1–V4), inferior (DII–aVF) and infero-lateral (DII–aVF/V4–V6/DI-aVL)) and by age. Results Overall, 2261 (mean age 12.4 years, 100% Caucasian) athletes were enrolled. TWI in ≥2 consecutive ECG leads was found in 136 athletes (6.0%), mostly in anterior leads (126/136, 92.6%). TWI in anterior leads was associated with TTE abnormalities in 6/126 (4.8%) athletes. TWI in extended anterior (2/136, 1.5%) and inferior (3/136, 2.2%) leads was never associated with abnormal TTE. TWI in infero-lateral leads (5/136, 3.7%) was associated with significant TTE abnormalities (3/5, 60.0%), including one hypertrophic cardiomyopathy (HCM) and two LV hypertrophies. Athletes with normal T waves had TTE abnormalities in 4.4% of cases, including one HCM with deep Q waves in infero-lateral leads. Conclusions In this broad population of peri-pubertal male athletes, TWI in anterior leads was associated with mild cardiac disease in 4.8% of cases, while TWI in infero-lateral leads revealed HCM and LV hypertrophy in 60% of cases. ECG identified all cases of HCM.

PURPOSE Endocannabinoids (eCB) and interleukin 6 (IL-6) levels change during physical activity, thus suggesting their involvement in the modulation of exercise-related processes like inflammation and energy homeostasis. To investigate whether lifestyle might affect the activity of the eCB-degrading enzyme fatty acid amide hydrolase (FAAH), active and sedentary subjects were enrolled. METHODS Plasma IL-6 levels and lymphocyte FAAH activity of eight physically active male subjects (mean ± SEM; age = 39.3 ± 2.9 yr, body mass index = 21.1 ± 0.4 kg·m), usually practicing aerobic exercise (8.1 ± 1.2 h·wk), and eight sedentary subjects (38.8 ± 3.7 yr, body mass index = 23.1 ± 0.8 kg·m) were measured. Also, in vitro effect of IL-6 was tested on FAAH expression and activity and on FAAH promoter activity in lymphocytes from sedentary subjects. RESULTS Under resting conditions (at least 12 h from the last exercise), the active group showed plasma IL-6 levels (2.74 ± 0.73 pg·mL) and lymphocyte FAAH activity (215.7 ± 38.5 pmol·min·mg protein) significantly higher than those measured in the sedentary group (0.20 ± 0.02 pg·mL, and 42.0 ± 4.2 pmol·min·mg protein). Increased IL-6 levels paralleled increased FAAH activity, and consistently, the in vitro treatment of lymphocytes from sedentary individuals with 10 ng·mL IL-6 for 48 h significantly increased FAAH expression and activity. Transient transfection experiments showed that IL-6 induced the expression of a reporter gene under the control of a cAMP response element-like region in the human FAAH promoter. A mutation in the same element abolished IL-6 up-regulation, demonstrating that this cytokine regulates FAAH activity at the transcriptional level. CONCLUSION IL-6 leads to activation of the FAAH promoter, thus enhancing FAAH activity that modulates the eCB tone in physically active people.

Regular physical activity is effective as prevention and treatment for different chronic conditions related to the ageing processes. In fact, a sedentary lifestyle has been linked to a worsening of cellular ageing biomarkers such as telomere length (TL) and/or specific epigenetic changes (e.g. DNA methylation), with increase of the propensity to aging-related diseases and premature death. Extending our previous findings, we aimed to test the hypothesis that 12 weeks of low frequency, moderate intensity, explosive-type resistance training (EMRT) may attenuate age-associated genomic changes. To this aim, TL, global DNA methylation, TRF2, Ku80, SIRT1, SIRT2 and global protein acetylation, as well as other proteins involved in apoptotic pathway (Bcl-2, Bax and Caspase-3), antioxidant response (TrxR1 and MnSOD) and oxidative damage (myeloperoxidase) were evaluated before and after EMRT in whole blood or peripheral mononuclear cells (PBMCs) of elderly subjects. Our findings confirm the potential of EMRT to induce an adaptive change in the antioxidant protein systems at systemic level and suggest a putative role of resistance training in the reduction of global DNA methylation. Moreover, we observed that EMRT counteracts the telomeres’ shortening in a manner that proved to be directly correlated with the amelioration of redox homeostasis and efficacy of training regime, evaluated as improvement of both muscles power/strength and functional parameters.

BackgroundA growing consumption of natural (plant-derived) dietary supplements with ergogenic aims, with particular regard for ecdysteroids, phytoestrogen s and vegetal sterols, has been registered over the last years among “recreational” athletes. The present study was carried out in order to evaluate the real knowledge of plant-derived nutritional supplements among physically active people as well as their real consumption. Additional aim was to evaluate the effects of these supplements on the health profile of the users.MethodsTwenty-three trained subjects who habitually used natural dietary supplements, and 30 matched controls were analyzed for plasma biochemical markers and hormonal profile.ResultsThe laboratory tests revealed the absence of any sign of organ toxicity/damage in both athletes and controls. On the contrary, hormone profiles revealed marked alterations in 15 (65%) out of the 23 of investigated athletes. Specifically, 10 males presented increased plasma levels of progesterone, 15 subjects presented abnormal estrogen levels, including 5 (2 F and 3 M) presenting a “dramatic” increased estrogen values and 2 two males with increased estrogen levels, increased testosterone levels and associated suppression of luteinizing hormone and follicle-stimulating hormone.ConclusionsThe results of the present study highlighted that the habitual consumption of plant-derived nutritional supplements is frequently associated with significant hormonal alterations both in male and female subjects. Although these biochemical alterations were not associated with signs or symptoms of organ toxicity/damage at the moment of the study, it cannot be excluded that, in the mid/long-term, these subjects would suffer of health problems secondary to chronic exposure to heavily altered hormonal levels. Further large scale studies are needed to confirm the results of this pilot study as well as to investigate the biological mechanisms at the base of the observed hormonal alterations.

Beyond fairness: the biology of inclusion for transgender and intersex athletes

Yannis Pitsiladis; Joanna Harper; Jonathan Ospina Betancurt; Maria-Jose Martinez-Patino; Attilio Parisi; Guan Wang; Fabio Pigozzi

In November 2015, the International Olympic Committee (IOC) reached a consensus on “Sex Reassignment and Hyperandrogenism” allowing transgender athletes to compete after one year of hormone replacement therapy (HRT) and without sex reassignment surgery (SRS). These recommendations have been applauded by some who argue that these guidelines are supported by the limited scientific data and are in line with current social and legal recognition on transgender issues. There are however, many who oppose allowing transgender women to compete against cisgender women under any conditions, especially in those cases where gonadectomy has not been performed. While much of this opposition is based on a lack of understanding of the transformative nature of HRT, there are also those who have legitimate concerns over the paucity of scientific studies to support the new IOC guidelines.

The purpose of the present study was to evaluate the effects of a 4-week low-carbohydrate (CHO) diet regimen on body weight, exercise performance and hormonal response to running in master athletes. Six endurance master athletes performed three 30-min time trials, before (TT1), after 15 days (TT2) and after 30 days (TT3) on a low CHO diet. Blood samples were collected for hormonal and lactate measurements. After 15 days body weight had decreased (TT1 72.3 ± 2.4 kg, TT2 70.0 ± 2.7 kg; P = 0.006) and then remained stable. No differences were observed in performance (TT1 7,015 ± 273 m, TT2 6,920 ± 286 m, TT3 7,202 ± 315 m) and in the insulin/glucagon ratio. After 2 and 4 weeks, adrenocorticotropic hormone decreased significantly both at rest (baseline: TT1 42.5 ± 7.8 pg·ml−1, TT3 21.6 ± 3.2 pg·ml−1) and during exercise (end of exercise: TT1 120 ± 20 pg·ml−1, TT2 80 ± 16 pg·ml−1, TT3 31 ± 2 pg·ml−1). Baseline cortisol concentrations had increased significantly after as little as 15 days on the low CHO diet. The results of the present study demonstrate no changes in time trial performance in master endurance athletes after 4 weeks on a low CHO diet. However, an effect on the hypothalamic pituitary adrenal axis emerged.
