Summary
Collegiate athletes experienced significant changes in body composition, with increased fat-free mass and decreased fat mass during intense training. These body composition shifts during breaks also impact athletic performance.
Area of Science:
- Sports Medicine
- Exercise Physiology
- Human Performance
Background:
- Body composition significantly influences athletic performance.
- Collegiate athletes face varied training intensities throughout seasons.
- Limited research exists on body composition changes during intense training and subsequent breaks.
Purpose of the Study:
- To track changes in collegiate athletes' body composition over an 11-week summer period.
- To analyze body composition shifts during intense training and detraining phases.
- To understand the implications of these changes on athletic performance.
Main Methods:
- Measured body weight and composition (fat-free mass, fat mass) in a collegiate men's basketball team.
- Utilized Dual X-ray Absorptiometry (DXA) scans at three time points: start of training, end of training, and after a break.
- Converted body composition measures into indices (kg/m²).
Main Results:
- Fat-free mass index increased significantly (p < 0.01) during the 7-week training period.
- Fat mass index decreased significantly (p = 0.01) during training and further decreased (p = 0.02) by the end of the summer.
- Fat-free mass index decreased post-training (p < 0.01), with no significant change in total body mass.
Conclusions:
- Cyclic changes in body composition occur during summer training periods in collegiate athletes.
- These fluctuations can potentially impact athletic performance.
- Further research is needed to identify mediators and moderators of these changes to optimize athlete and team performance.

Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions...

01:27Signs of Puberty
353
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

01:09Changes in the Appendicular Skeleton with Age
2.0K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:29Bone Disorders
3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:21Skeleton and Calcium Homeostasis
4.5K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

01:27Exercise and Muscle Performance
1.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
