The prevalence of musculoskeletal injuries in sweep rowing is high. As nearly 50% of power during sweep rowing is contributed by the legs, the presence of muscle imbalances may predispose rowers to overuse injuries. The purpose of the study was to assess knee muscle strength symmetry between dominant and non-dominant limbs of male and female rowers. A descriptive, quantitative research design was used. Twenty-four male and 13 female rowers aged 18–26 years participated. Bilateral isokinetic knee flexion and extension peak torque and hamstrings/quadriceps (H/Q) ratios were assessed at 60°/s and 180°/s using an isokinetic dynamometer. The data was analysed using Mann-Whitney U and Wilcoxon rank tests and significance was set at p≤0.05. In males, the dominant knee extension torque values at 60°/s and 180°/s were significantly larger than that of the non-dominant side (p≤0.05). In females, the non-dominant eccentric H/Q ratio at 60°/s was 15% larger than that of the dominant side (p=0.019). Bilateral differences observed in knee extension torque for males and in H/Q ratio for females highlight the need for isokinetic testing of sweep rowers, to improve performance and prevent injury.

The objective was to compare cardiorespiratory parameters between two graded exercise protocols to determine which one is most appropriate for training prescription for male university level distance runners. The graded exercise tests, namely the Adapted Incremental Speed Protocol (AISP), and the Adapted Non-Motorised Incremental Speed Protocol (ANMIP) was used to compare several cardiorespiratory responses, as well as two intensity markers: the ventilatory threshold (VT) and the respiratory compensation point (RCP). The maximal oxygen consumption ( ) value of the ANMIP significantly (p<0.05) exceeded that of the AISP within a significantly (p<0.05) shorter time frame (8:19±0:52 vs. 11:25±1:11min). The percentage of where VT and RCP were attained, was significantly higher (p<0.05) on the ANMIP (84.11±4.25 vs. 97.16±2.35%) compared to the AISP (75.74±7.84 vs. 93.3±3.86%). Consequently, the ANMIP is perceived substantially more difficult, both physiologically and psychologically. It can therefore be considered an ideal training tool to intensify exercise load with more time efficient training sessions for a distance running population. However, the obtained results during the ANMIP could overestimate exercise prescriptions and should therefore not be used for these purposes.
目的是比较两种分级运动方案之间的心肺参数，以确定哪一种最适合男性大学水平长跑运动员的训练处方。分级运动试验，即适应增量速度方案(AISP)和适应非机动增量速度方案(ANMIP)用于比较几种心肺反应，以及两个强度标记:通气阈值(VT)和呼吸代偿点(RCP)。ANMIP组的最大耗氧量()值在较短的时间内(8:19±0:52 vs. 11:25±1:11min)显著(p<0.05)超过AISP组(p<0.05)。ANMIP组VT和RCP达到的比例(84.11±4.25 vs. 97.16±2.35%)明显高于AISP组(75.74±7.84 vs. 93.3±3.86%)(p<0.05)。因此，无论在生理上还是心理上，ANMIP都被认为要困难得多。因此，它可以被认为是一种理想的训练工具，以加强运动负荷，为长跑人群提供更有效的训练课程。然而，在ANMIP期间获得的结果可能高估了运动处方，因此不应用于这些目的。

The recreation profession is a fast-growing, diverse, career field, creating unique challenges for academic institutions in preparing students. Not all the skills and competencies (graduate attributes) needed by entry-level recreation professionals can be achieved through academic curricula in classroom settings. Experiential learning pedagogy may address these challenges for recreation education. The Twin-Cycle Experiential Learning model (TCELM) can incorporate field- and classroom-based experiential learning into degree programmes. The purpose of this article is to investigate the experience of students in a recreation module that implemented an adapted TCELM. A holistic single-case is reported with qualitative data including student reflections, lecturer reflections and focus group interviews, subject to inductive coding. The merit of both cycles of the TCELM in student learning was examined. Group work and time management were two factors identified that may challenge the implementation of experiential learning. However, both these factors contribute to the development of essential skills for the workplace. It was concluded that the adapted TCELM is practically implementable within a recreation module at a higher education institution. However, attention should be given to student expectations, active learning opportunities and the time spent on experiential learning activities.

This paper aims to compare the effects of functional exercises and basketball training on forward head posture, lumbar hyperlordosis, and motor skills of 45 obese children aged 10 years with forward head posture and hyperlordosis. The children were randomly included to the functional exercise, basketball and control groups for 12 weeks. The angles of lumbar lordosis and craniovertebral were recorded as biomechanical variables. Bruininks-Oseretsky Test of Motor Proficiency - Brief Form (BOTMP-BF) was used to determine motor skills of the children. Forty-two children completed the study. All groups had similar angles for lumbar lordosis after 12 weeks (p>0.05), whereas craniovertebral angle significantly decreased in the control group only (p<0.05). Both functional exercise and basketball were effective in improving speed and agility. There was a statistically significant increase in the total BOTMP-BF score of the functional exercise group (p<0.001). Both types of physical activity may be a way of managing the progression of forward head posture, whereas they did not affect lumbar posture. Functional exercises and basketball affected different aspects of motor skills.

Adolescence is a crucial developmental stage of growing and development. This stage is characterised by physiological and psychological changes, such as changes in body composition and self-efficacy. The aim of this study was to investigate the relationship between certain body composition components and self-efficacy among 12- to 14-year-old rural boys (n=49) and girls (n=43). The anthropometrical measurements included body mass, body stature, three skinfold sites, waist and hip circumferences and were used to determine Body Mass Index (BMI), fat percentages and waist-to-hip ratio (WHR). The Self-Efficacy Questionnaire for Children (SEQ-C) was used to measure general self-efficacy. Descriptive statistics and the Pearson product-moment practical correlation for analysis of data was performed. Only girls presented significantly high practical correlations between BMI and emotional self-efficacy (r=0.33, p=0.02), total self-efficacy and WHR (r=0.44, p=0.00), social self-efficacy and WHR (r=0.39, p=0.01), and emotional self-efficacy and WHR (r=0.33, p=0.02). The boys presented significant and positive practical correlations between social self-efficacy and body mass (r=0.31, p=0.02) and body stature (r=0.39, p=0.00). The findings seem to suggest that the practical correlations between body composition and self-efficacy could be specific to certain cultures and specific countries. Keywords: Self-efficacy; Body composition; Rural children; Body Mass Index; Fat percentage; Waist-to-hip ratio.
