The Effect of Fasting on some Physiological, Physical, and Skill Indicators, and Perceived Intensity among Handball youth by Mai Rawashdih

 Objectives of the Study:

The study aimed to examine the effects of fasting during Ramadan on certain physiological, physical, and skill-related indicators, as well as perceived exertion among junior handball players in Jordan. It sought to identify differences in variables like VO₂ max, heart rate, speed, explosive power, flexibility, endurance, shooting accuracy, dribbling, passing, receiving, and perceived exertion across three time points: before, during, and after Ramadan.

Methodology:

The study employed a descriptive approach, with a sample of 12 junior national handball players selected deliberately. Measurements were conducted in three phases: a week before Ramadan, the fourth week of Ramadan, and the fourth week after Ramadan. Physiological and physical tests, including the Beep Test, were used alongside skill-based assessments. Statistical analyses involved repeated measures ANOVA, means, standard deviations, and LSD tests to determine significant differences.

Physiological Variables & Measurement:

Key physiological variables measured included:

VO₂ max (predicted): Assessed using field tests to estimate aerobic capacity.

Heart Rate (HR): Monitored before and after exertion to observe changes due to fasting.

Other physical measures covered speed, explosive strength, flexibility, and endurance. Skill tests evaluated shooting accuracy, dribbling, passing, and receiving.

Results:

Decreased heart rate before and after the Beep Test during Ramadan.

Improved shooting accuracy, passing, and receiving during Ramadan.

Faster sprint times in Ramadan (average 3.15 seconds) compared to pre-Ramadan (3.41 seconds).

No significant differences in perceived exertion (RPE) across all phases.

The study recommended further research to analyze performance changes at different stages of Ramadan to optimize athletic preparation during fasting periods.

The Effect of Menstrual Periods on Some Physical and Physiological Aerobic and Anaerobic Capabilities in Taekwondo Players in Jordan. By Rana Albaradi

Objectives of the Study:

Primary Goal: To analyze how different phases of the menstrual cycle affect the performance of taekwondo players, specifically focusing on aerobic and anaerobic capacities.

Hypothesis It may be hypothesized that various menstrual cycle phases could either enhance or hinder physical performance due to hormonal fluctuations.

Methodology

Participants*: The study would involve a sample group of female taekwondo athletes from Jordan. Participant characteristics, such as age, training level, and menstrual cycle regularity, would be noted.

Physiological Variables: measurement of variables such as heart rate, lactate levels, and perceived exertion during training and competition.

Expected Outcomes

Performance Variability : It is anticipated that the study will highlight any significant variability in performance metrics across different menstrual phases.

Physiological Responses: Changes in heart rate, recovery time, and overall fatigue may be observed depending on the menstrual cycle phase.

Recommendations : The findings may lead to tailored training and competition strategies for female athletes during various phases of their cycle to optimize performance.

Significance of the Study

The findings would contribute to the broader understanding of female athlete physiology and performance, emphasizing the need for personalized training programs that consider menstrual health.

The study could encourage coaches and trainers to be more considerate of female athletes’ menstrual health in their training regimens.

Conclusion

Research like this is crucial for enhancing female athletic performance and ensuring optimal health and well-being in sports contexts.

The Effect of Aerobic Exercise at Various Intensities on Intraocular Pressure "Iop" in Physical Education Students by Fatima Alfaqi

The study titled "The Effect of Aerobic Exercise at Various Intensities on Intraocular Pressure (IOP) in Physical Education Students" investigates how different intensities of aerobic exercise can influence IOP, which is a critical factor in eye health and can affect conditions like glaucoma.

Objective: To determine the relationship between varying intensities of aerobic exercise and changes in intraocular pressure among physical education students.

Methodology:

Participants: A group of physical education students would be selected for the study.

Exercise Protocol : Participants could be subjected to aerobic exercises at different intensities, such as low, moderate, and high.

Measurement of IOP: Intraocular pressure would be measured before and after the exercise sessions using a tonometer.

Hypothesis: The study may hypothesize that aerobic exercises, particularly at certain intensities, could result in a significant change in IOP levels.

Results: The outcome could reveal whether increased intensity in aerobic exercise is correlated with a decrease or increase in IOP, contributing to understanding the implications of physical activity on eye health.

Conclusion: Results could provide insights into how physical education programs might benefit eye health and inform practices for students at risk of elevated IOP.

This study could contribute to the broader understanding of the interplay between physical activity and ocular health, emphasizing the importance of regular exercise in maintaining

overall well-being.

HANDGRIP STRENGTH AND ITS RELATIONSHIP TO SOME PHYSICAL MEASUREMENTS FOR HEALTHY PATIENTS, CARDIOVASCULAR DISEASE AND DIABETES

By: Zaid Radi Eid Al-Ayyoub

Supervisor: Dr. Ibrahim Mefleh Elayyan Dabayebeh, Prof.; Co-Supervisor: Dr. Philippe Noirez, Prof

This study aimed to identify hand grip strength and its relationship to some physical measurements in healthy individuals and hypertension, diabetes, and cardiovascular disease patients. The descriptive method was used due to its suitability for the nature and objectives of the study.

Handgrip Strength Measurement:

HGS is typically measured using a dynamometer, which gives an objective evaluation of an individual’s hand strength. It's a simple test that's easy to administer and requires minimal equipment.

Physical Measurements:

Researchers often correlate HGS with various physical measurements, including:

Body Mass Index (BMI): Higher BMI often relates to lower HGS in some populations.

Waist Circumference: Increased waist circumference can indicate central obesity, which may negatively impact muscle strength.

Muscle Mass: Studies examine the relationship between HGS and overall muscle mass, which tends to decline with age and inactivity.

Implications for Heart Health:

Handgrip strength has been shown to be an independent predictor of cardiovascular health. Low HGS is associated with:

Higher blood pressure.

Poorer lipid profiles (higher triglycerides, lower HDL cholesterol).

increased risk of heart disease and stroke.

Diabetes and HGS:
In patients with diabetes, lower HGS may indicate poor glycemic control and increased risk of complications. Research often looks at:

The impact of diabetes duration and control on muscle strength.

Differences in HGS among various diabetes types (Type 1 vs. Type 2).

Age and gender differences:

Studies typically explore how age and gender affect HGS. For example, men generally exhibit higher HGS than women, and strength tends to decline with older age.

Functional Outcomes:

HGS is frequently linked to functional outcomes, such as balance and mobility. Poor grip strength is associated with a higher risk of falls in older adults, which can lead to serious health complications.

Some research suggests that interventions like resistance training or nutritional modifications can improve HGS, potentially benefiting cardiovascular health and diabetes management.

Conclusion:

Understanding the relationship between handgrip strength and health conditions like cardiovascular disease and diabetes can help healthcare professionals identify at-risk individuals, design appropriate interventions, and improve overall health outcomes.
