Physical exercise increases adult hippocampal neurogenesis in male rats provided it is aerobic and sustained
2016
Aerobic exercise, such as running, has positive effects on brain structure and function, such as adult hippocampal neurogenesis (AHN) and learning. Whether high-intensity interval training (HIT), referring to alternating short bouts of very intense anaerobic exercise with recovery periods, or anaerobic resistance training (RT) has similar effects on AHN is unclear. In addition, individual genetic variation in the overall response to physical exercise is likely to play a part in the effects of exercise on AHN but is less well studied. Recently, we developed polygenic rat models that gain differentially for running capacity in response to aerobic treadmill training. Here, we subjected these l…
Effects of a 10-day high-intensity interval training mesocycle on physical performance in male judo athletes
2020
Judo is an Olympic combat sport where the competition emphasizes several consecutive 20-30 seconds high-intensity efforts interspersed by short recovery periods. High-intensity block training has been found to be an efficient way to develop physical performance, wherein shorter training periods are focused on developing one or two chosen physical abilities. The purpose of this study was to investigate the effects of a 10-day high-intensity interval training period on the performance in male judo athletes. The study included pre and post-tests as well as a 10-day training intervention. The subjects were 19-28 years old men who had competed at least at the Nordic level during the last year (n…
Neuromuscular fatigue after short-term maximal run in child, youth, and adult athletes
2013
Johdanto ja tutkimuksen tavoite. Aikaisempien tutkimusten perusteella on havaittu että esipuberteetti ikäiset lapset väsyvät vähemmän ja palautuvat nopeammin kuin aikuiset kovatehoisten urheilusuoritusten yhteydessä. Nuoren urheilijan kypsymiseen liittyvät muutokset perifeerisissä ja hermostollisissa väsymysmekanismeissa ovat kuitenkin vielä selvittämättä. Tämän tutkimuksen tavoitteena on tuottaa uutta tietämystä iän ja kypsymisen vaikutuksista perifeeristen ja hermostollisten mekanismien rooliin 50 s maksimaalisessa juoksusuorituksessa. Menetelmät: Tutkimukseen osallistui 24 miespuolista koehenkilöä jotka jaettiin kolmeen ikäryhmään: Lapset (N = 8; 11.9 ± 1.4 v), Nuoret (N = 8; 14.9 ± 1.1 …
