The present study investigated the effect of three goal-setting groups (self-set, assigned, and control) and three levels of self-efficacy (low, medium, and high) on bowling performance of college students (N = 288). The performance/retention trials were analyzed in a 3 × 2 × 10 (Goal Conditions × Self-Efficacy Levels × Trials) ANCOVA design, with repeated measures on the last factor and baseline performance as the covariate. Results of the data analysis revealed a significant main effect for self-efficacy (SE) levels for males and females. Individuals at high and medium SE levels performed significantly better than those at a low SE level. The nonsignificant main effect for goal groups was attributed to the spontaneous goal-setting behavior of the control group. Finally, there was a main effect for trials and planned comparisons indicated that as trials progressed female students improved. Evidence of a performance plateau was present for male students, as they showed marginal improvement across trials.

Background. The effectiveness of outpatient mobile laser intervention on specific treatment goals has not been fully explored. Thus, the aim of the study was to examine the effect of orthopaedic knee brace with laser on knee joint function, pain and swelling. Methods. Volunteers were divided into two experimental groups: chronic pain (n = 20, knee pain > 6 months) and acute pain (n = 20, knee pain < 1 week), and one control (n = 20, placebo) group. Subjects in all groups were immobilized in a knee brace for 4 weeks. In addition, the experimental groups underwent low-intensity laser therapy, whereas control group underwent pseudo-laser therapy, every second day for 10 min. The sequences of the tests were as follows: (a) clinical assessments and evaluation of knee extension and flexion amplitude, swelling, Lysholm subjective assessment questionnaire, VAS pain scale, (b) evaluation of balance using Kistler platform, (c) muscle peak torque and isometric torque variability assessment using isokinetic dynamometry. All tests were performed twice - before and after intervention. Results. Knee brace with laser is effective treatment for the reduction of pain, swelling, and recovering of daily functions (p < .05). Operation of the complex device is particularly effective in treating knee pain in the acute period (p < .05). Conclusions. Knee brace with laser therapy in the rehabilitation period ensures faster healing of patients compared to wearing only knee brace, particularly in acute pain, while muscle strength and proprioception remains depressed.

This study examined the effect of integrating Statistical concepts on Third year student teachers’ academic performance on Heredity in Biology. The study adopted purposive sampling where 93 participants were randomly assigned into two groups, i.e. an Experimental class (n = 45) and a Control group (n = 48).Three research questions and two hypotheses guided the study. The study used a quasi-experimental pretest-posttest control group design. Data were collected using a 8-item structured questionnaire which was used to obtain data on students’ attitude towards heredity while an Achievement Test’ (AT), which comprised 4 questions, was used to measure the students’ performance in genetics. The two null hypotheses were tested using the Independent Sample T-test (at α = 0.05) while the third question was analysed using percentages.The findings from the study showed that students taught Heredity by integrating statistical concepts achieved higher scores and significantly better than those taught using conventional methods (df = 91; p = 0.001 < α = 0.05) . There was also no better achievement in favour of the male students compared to their female counter parts when taught by integrating the statistical concepts in the experimental group (df = 43; p = 0.871 > α = 0.05). It further established that students developed positive attitude towards Heredity after integrating statistical concepts in the teaching of Heredity in Biology. The study recommends among other things, that since integrating statistical concepts is found to be an effective strategy and enhanced achievement among Biology students, teachers and lecturers of this subject should accept it as one of the strategies they can use in teaching Heredity in Biology so as to enhance students’ academic performance.

PURPOSE: This study aimed to examine the effects on the hamstring/quadriceps ratio (H/Q ratio) and H/Q ratio fatigue index (H/Q FI) of the knee joint of an 8-week weight training to improve the hamstring muscles of male college students.METHODS: Twenty male college students were divided into two groups: an exercise group (EG) and a control group (CG). The EG participated in an 8-week hamstring weight training program, working out twice a week, 60 min per session, with a 60–80% 1RM and 12–16 RPE intensity. The peak torque, H/Q ratio, and H/Q FI were measured, and a t-test was used to verify the statistical significance of the difference between the pre- and post-intervention results.RESULTS: The right flexor peak torque at 60°/sec increased by 14.10±9.60%BW in the EG and decreased by −9.00±16.55%BW in the CG, showing a significant difference between the groups (<i>p</i><0.01). The left flexor peak torque increased by 6.60±12.31%BW in the EG and decreased by −5.10±10.68%BW in the CG, showing a significant difference between the groups (<i>p</i><0.05). The left extensor peak torque decreased by −5.40±19.53%BW in the EG and by −28.40±25.70%BW in the CG, showing a significant difference between the groups (<i>p</i><0.05). The H/Q ratios tended to increase, but the difference was not significant.CONCLUSIONS: To prevent injuries and stabilize the knee joint, the central joint of the lower extremity that plays an important role in daily life and sports activities, hamstring weight training can be performed to maintain the H/Q ratio within the normal range.

ABSTRACT Introduction: The knee joint is a complex and important joint in the human body. It plays an active role in maintaining posture balance of the human body in sports, allowing one to bear a larger load and complete various complex technical movements. Objective: To investigate the stability and influence of kinemechanics in knee joint rehabilitation training. Methods: A total of 80 patients with anterior cruciate ligament injury who received treatment in Henan Provincial People's Hospital were selected and divided into control group and observation group according to the random number table method, with 40 cases in each group. Results: Six months after surgery, the peak torque (PT), peak torque to body weight ratio (PT/BWT), total work (TWT), Lysholm score and Tegner score, and knee circumference of the two groups were significantly improved compared with those before surgery (P <0.01). The degree of improvement was greater in the observation group:compared with the control group, the difference was highly statistically significant (P<0.01). Conclusions: Professional exercise rehabilitation has a definite effect on patients after anterior cruciate ligament reconstruction. It can significantly improve the muscle strength of quadriceps and hamstring, improve the function of knee joint and promote its recovery.

Abstract. Several studies have shown that Continuous Performance Tests (CPT) can diagnose Attention Deficit Hyperactivity Disorder (ADHD) better than other tests. Research reporting comparisons of two or more CPT-type tests is scarce. The purpose of the study was to compare the Mathematics Continuous Performance Test (MATH-CPT) with another CPT-type test (CPT II) and a questionnaire (the Brown Scale). The comparison was carried out by looking at correlations among subscales and checking the precision of detecting ADHD. Ninety-five high school and college students participated in the study, 41 with ADHD were the research group and 54 were the control group. The participants performed the two tests and answered the questionnaire. The results showed that the MATH-CPT correctly identified 74.50% of the participants of both groups as compared to the 71.60% of the CPT II. Correlations between the two CPT-type tests were moderate; however, they were similar to correlations found in other studies comparing similar tools. The MATH-CPT, final attention formula, showed significant correlations with the Brown scales, while the CPT II, confidence index associated with ADHD assessment, showed nonsignificant correlations with the questionnaire. The study indicated that MATH-CPT can be used with a clinical population of ADHD and for research purposes.
