Investigating strength and range of motion of the hip complex in ice hockey athletes

CONTEXT: Ice hockey athletes frequently injure the hip complex via a non-contact mechanism. We investigated patterns of strength and range of motion (ROM) to establish major differences compared to soccer athletes. Soccer athletes were compared to ice hockey athletes due to similarities between the two sports with regards to the intermittent nature and high number of lower limb injuries. OBJECTIVE: To compare the differences in ROM and strength of the hip for both the dominant (Dom) and non-dominant (Ndom) limb in ice hockey and soccer athletes. DESIGN: Case control study. SETTING: Bilateral ROM in hip flexion in sitting (FS) and lying (FL), extension, abduction, adduction, and internal rotation (IR) and external rotation (ER) was measured using a goniometer and assessed for strength using a hand held dynamometer on both the Dom and Ndom limbs. Participants. Twenty four male, active, uninjured NCAA division III ice hockey (16) and soccer (8) athletes. MAIN OUTCOME MEASURE: ROM and strength for hip FS, FL extension, abduction, adduction, IR and ER. A mixed model ANOVA was used to investigate interactions and main effects. RESULTS: Ice hockey athletes exhibited greater hip adduction ROM compared to soccer athletes in the Dom leg (both p=0.002) and when both limbs were combined (p = 0.010). Ice hockey athletes had less ROM in ER (p = 0.042) than soccer athletes. Ice hockey athletes displayed less strength in adduction in their Ndom leg compared to their Dom leg (p=0.02) along with less adduction than soccer players in their Ndom leg (p=0.40). Ice hockey athletes displayed less strength in hip adduction (p=0.030), FS (p=0.023) and FL (p=0.030) than soccer athletes. CONCLUSIONS: Our findings suggest that ice hockey athletes may present an 'at risk' profile for non-contact hip injuries, in comparison with soccer athletes with regards to strength and ROM of the hip

FAPRI 1998 World Agricultural Outlook

The Food and Agricultural Policy Research Institute (FAPRI) prepares in the late fall of every year a preliminary baseline based on agricultural production, consumption, and trade. This is followed by an extensive outside review, re-evaluation of projections, and completion of the final baseline in January. The baseline assumes continuation of current agricultural and trade policies by world governments and assumes normal weather in the future. Macroeconomic assumptions on world general economic activity are derived from both Project LINK and the WEFA Group projections

FAPRI 2007 U.S. and World Agricultural Outlook

The FAPRI 2007 U.S. and World Agricultural Outlook presents projections of world agricultural production, consumption, and trade under average weather patterns, existing farm policy, and policy commitments under current trade agreements and custom unions. The outlook uses a macroeconomic forecast developed by Global Insight

FAPRI 2006 U.S. and World Agricultural Outlook

The FAPRI 2006 U.S. and World Agricultural Outlook presents projections of world agricultural production, consumption, and trade under average weather patterns, existing farm policy, and policy commitments under current trade agreements and custom unions. Despite continued high energy prices, world economic growth is expected to remain strong in the coming decade, above 3% per annum. Other major drivers of the 2006 baseline include new bio-energy policies in several large countries, EU sugar policy reform, sanitary and phytosanitary (SPS) shocks in livestock and poultry markets, and movements in the exchange rate.Crop Production/Industries, International Relations/Trade, Livestock Production/Industries,

FAPRI 1997 U.S. Agricultural Outlook

The Food and Agricultural Policy Research Institute develops a long-term outlook for the world agricultural sector once each year. While the initial steps to develop the new baseline start as soon as the previous year’s baseline is completed, the work begins in earnest in September and October with a discussion of policy and macroeconomic assumptions as well as a review of the models to be used in the upcoming exercise. The preliminary baseline is developed in November and that preliminary baseline is then shared among a number of reviewers. During the first or second week of January, more than 100 respondents are brought together for a two-day review process. Each segment of the baseline is presented and examined in a frank and open exchange of views. Subsequent to that review, the preliminary baseline is finalized

Residents Teaching Medical Students: How Do They Compare With Attending Educators?

PurposeEducating medical students is a core mission of academic radiology departments. In some programs, residents participate in student teaching. The aim of this study was to retrospectively compare medical student evaluations of radiology resident lectures with lecture evaluations of radiology faculty members.MethodsNumeric evaluations for lectures given by faculty members, fellows, and residents were collected over a 1-year period as part of routine course evaluations for a fourth-year medical student radiology elective. Faculty member, fellow, and resident lecture scores were compared, overall using analysis of variance and pairwise using Student's t test. A predefined low P-value threshold was used for the t tests to account for the multiple comparisons. To account for the inherent clustering of the data due to repeat lecturers, the data were reanalyzed on a "per lecturer" basis.ResultsThree hundred seven individual lecture scores were collected. There was no statistical difference between the lecture scores received by attending faculty members (mean, 9.10 on a scale of 10) and residents (mean, 8.99) (P = .08). Fellows, however, scored statistically significantly lower (mean, 8.45) than attending faculty members and residents (P <.001 for both comparisons). The per lecturer analysis yielded similar results.ConclusionsLectures delivered by residents received similar evaluations as lectures delivered by faculty members. Given that teaching can be an educational experience for residents, involving radiology residents in medical student teaching may benefit students and residents alike
