Physical activity, age, physiological functions

Stephen D. R. Harridge and Norman R. Lazarus, Physiology, 32: 152–161, 2017.

At the anatomical level, muscle loss in older people is associated with atrophy of fast-contracting, type II muscle fibers. Indeed, it has been suggested that type II fiber atrophy might completely explain the loss of muscle bulk in later life. However, a prevailing view is that skeletal muscle loss also relates to a loss of muscle fibers secondary to a loss of motor units. Partial re-innervation of abandoned fibers is believed to occur, resulting in an increased size of remaining motor units, with knock-on effects for fine motor control. This hypothesis is supported with histological evidence of fiber-type grouping and through electromyo- graphic estimates of motor unit number.

Whereas evidence of streaming of Z line and rod formation, and angulated fibers further point to dysregulation of skeletal muscle in later life (81). Studies of mas- ter athletes paint a very different picture (as illustrated in FIGURE 3), which once more challenges the assertion that these changes can be explained by an inherent aging process and are inevitable consequences of getting older.

Images taken across the mid region of the thigh, showing a sarcopenic muscle (middle) from a sedentary individual with reduced contractile mass, more subcutaneous fat, and infiltration of fat and connective tissue. By contrast, the muscles of a similarly aged master triathlete (bottom) shows little difference to that of a younger athlete (top).

Walk, run and think right

Armando Spataro, state’s attorney in Turin, will retire in a few weeks. Spataro is also a runner and marathoner and  Lawyers Association of Turin decided to greet him in a thoroughly unpredictable and so far ever made.In fact they organized in his honor, the “Walk, run and think right”, the first sport event inside a palace of justice. On 21 December at 14 pm, judges, journalists, lawyers, personal, and obviously law enforcement agencies will walk or run inside the palace of justice. Even the award is quite unusual.

The winners of category will have 9 minutes to greet him, the latest one minute. Finally in order to subscribe: “each category or team must deposit before December 20″ four folders “, one containing the greeting to the state’s attorney, and three on “the justice I wants.”

When we want sport and civil rights go hand in hand!

A common bias: the warmup is useful to avoid the injuries

There’s a lot of confusion among athletes in relation to the warmup function.

For some is practiced to avoid getting hurt.

For others it’s something to do well just before the races, but during the training they do not do ever in that way.

For almost everyone it’s a rather boring phase in which to prepare to start very well the competition.

It is often regarded like a school homework and it’s performed without conviction and with a reduced mental effort.

For example, almost no guy gets exhaling during the stretching. Let us remember that the first determines the later. Then bad stretching corresponds to a limited elongation and reduced muscle distension, with all the negative consequences coming if this kind of execution is repeated over time.

  • Fra i praticanti, il 24,4% lo fa in modo assiduo e il 9,8% saltuariamente.
  • La mancanza di tempo è la “scusa” più usata da chi non frequenta piscine o palestre, ma ci sono anche motivi di salute o di scarso interesse fra le varie giustificazioni da utilizzare.
  • Il 26,5% delle persone che preferisce fare movimento attraverso lunghe passeggiate a piedi o in bicicletta.
  • Tra gli uomini il 29,5% fa sport con continuità e l’11,7% di tanto in tanto.
  • Per le donne le percentuali sono più basse, rispettivamente 19,6% e 8,1%.
  • La pratica sportiva continuativa cresce nel tempo per entrambi i generi e in tutte le età: dal 15,9% del 1995 al 22,4% nel 2010 fino al 24,5% nel 2015.

Epilepsy and sports

Epilepsy and sports is still a relation not well investigated and especially little practiced. This is because many people continue to believe that sports can be a stress that trigger seizures. Research has shown that this probability is smaller in relation to physical activity than it is on normal daily activities. The question is not about whether playing sports, it regards what are the recommended sports and ones to avoid and how to obtain the medical certification at least to practice non-competitive sports. Also, it needs to remember that a forced sedentary lifestyle causes other problems, typical in those who don’t practice sports as cardio-circulatory problems, type-2  diabetes, breast and colon cancer as well as psychopathological disorders (depression and anxiety). The epilepsy day world should be a time of reflection and proposals on these issues, which will be tackled effectively not individually but only with collaborative networks among the families of these patients, the healthcare system, sports clubs and psychologists and medical experts.

World ranking of Sport Science Schools and Departments

ShanghaiRanking’s Global Ranking of Sport Science Schools and Departments has been published few days ago. It is the first attempt to rank a group of institutions & units with the same subject focus. Since the publication of the Academic Ranking of World Universities (ARWU) by academic subjects in 2009, ShanghaiRanking has been constantly seeking ways to expand the subjects been covered. In June 2016, ShanghaiRanking produced rankings of universities in 7 engineering subjects in order to provide insights into universities’ academic competences in more subject areas.

The world’s sport industry is undergoing enormous growth. Using China as an example, based on Nielsen’s latest data, China aims to create an $813 billion sport industry by 2025 and Chinese companies and wealthy individuals are encouraged to invest heavily in sports events, teams, facilities, agencies and sponsorships, inside and outside the country. Sport Science schools equip students with knowledge and skills to meet the needs of this fast-growing industry, and also to create scholarly knowledge to support and inspire this industry. ShanghaiRanking choose to start its ShanghaiRanking’s Global Ranking of Sport Science Schools and Departments.

A great amount of work is devoted to identify academic units, such as university, schools, faculties, and departments, which engage significantly in Sport Science research. A total of 110,000 unit addresses were examined and hundreds of websites searched to form the final list of 361 universities or about 400 sport-related units that actively engage in research. The top 300 universities are published in this ranking based on the measurement of publication, citation, citations per publication, top 25% journals publications, and internationally collaborated publications.

European universities dominate this year’s ranking list. There are 144 European institutions on the top 300 list. More than half of these units are from the United Kingdom, Spain and Germany with 45 units, 16 units, and 15 units respectively. Loughborough University’s School of Sport, Exercise and Health Sciences is the highest ranked unit in Europe and is ranked second in ShanghaiRanking’s Global Ranking of Sport Science Schools and Departments 2016.

103 institutions are from Americas. 64 of these units are from the United States and the country has the strongest presence in ShanghaiRanking’s Global Ranking of Sport Science Schools and Departments 2016 than other countries. Also strongly performed, 25 institutions from Canada and 14 from Brazil are listed in the ranking this year.

Deakin University’s School of Exercise and Nutrition Sciences from Australia took the first place in the ranking. 51 institutions are from Asia and Oceania and more than 90% of these institutions are from Australia, China, Japan, and New Zealand. New Zealand universities have outstanding performance as 6 out of 8 public universities from the country are presented in the ranking and AUT University’s School of Sport and Recreation is ranked in the top 30.

Two institutions are from Africa. University of Cape Town’s Division of Exercise Science and Sports Medicine is ranked 48th.
