Acute injuries in Finnish junior floorball league players
Abstract Objectives To investigate the incidence and characteristics of acute time-loss injuries in Finnish junior floorball league players. Design Prospective cohort study with 3-year follow-up. Methods One hundred and eighty-six female and male players (mean age 16.6 ± 1.4) took part in the follow-up study (2011–2014). The training hours and games were recorded on a team diary. Floorball related acute injuries were registered and verified by a research physician. The injury incidence was expressed as the number of injuries per 1000 h of exposure. Incidence rate was calculated separately for games and practices, and for males and females. Results One hundred and forty-four acute time-loss …
Use of dietary supplements and anabolic-androgenic steroids among Finnish adolescents in 1991-2005.
Background : The aim of the study was to describe the prevalence, trends and associated factors of dietary supplements (DS) and anabolic-androgenic steroids (AAS) use among Finnish adolescents. Methods: The sample comprised 30 511 adolescents aged 12–18 years, of which 22 519 (74%) answered a questionnaire. We also studied associations between 14 socioeconomic, health and health behavioural variables and DS and AAS use by logistic regression. Results: The proportion of respondents using DS was 45% during the past year and it increased linearly by age. Vitamins (37%) and herbal products (13%) were the most common DSs. In 1991, 9% of the boys aged 16–18 years reported protein use, while the f…
Low back pain during military service predicts low back pain later in life
The aim of the present study was to assess associations between physician diagnosed unspecified low back pain (LBP) during compulsory military service and self-reported LBP and physical fitness measured on average four years after military service. From a total of 1155 persons who had been pass medical examination for military service and who had completed physically demanding military training between 1997 and 2007, 778 men participated in a refresher military training course and physical tests. In this study, the association between LBP during military service and LBP in later life in addition to the association between LBP and physical fitness were examined. A total of 219 out of 778 par…
Association between lower extremity muscular strength and acute knee injuries in young team‐sports athletes
The purpose of this study was to investigate LE muscular strength variables as potential risk factors for all and non‐contact acute knee and ACL injuries in young athletes. A total of 188 young (≤21) male and 174 female basketball and floorball players participated in LE muscular strength tests and were followed up to three years. The strength test battery consisted of 1RM leg press, maximal concentric isokinetic (60°/s) quadriceps and hamstrings and maximal isometric hip abductor strength. The outcomes were a new acute knee or ACL injury and a new acute non‐contact knee or ACL injury. A total of 51 (17 in males and 34 in females) new acute knee injuries registered and 17 (one in males and …
