Traditionally, there are two pedagogical approaches to teaching human anatomy. The first is the systems-based approach (study of body systems - bones, muscles, organs - separately) gross anatomy courses and the second is the segmental-based approach (study of body segments - upper and lower limbs and trunk - separately); both are highly recommended. However, to the best of our knowledge, less is known about academic performance comparing the two approaches.

Objective: The study intended to evaluate the differences between active and sedentary postural control and isokinetic trunk strength. The secondary aim was to evaluate the participants' total physical activity (PA) score regarding the specific quality of life domains assessed.

Methods: An analytical cross-sectional study involving 64 participants of both sexes aged ≥60 years (60-86 years) was conducted.

Article Synopsis
  • Ultramarathon running, especially 24-hour races, is becoming increasingly popular, yet there's limited knowledge about the origins of top runners and their fastest race locations.
  • A study utilizing a machine learning model analyzed over 171,000 race records and found that the majority of athletes come from the USA and Europe, with Tunisians showing the fastest average speeds.
  • The study revealed a strong connection between an athlete's country of origin and the race location, with the fastest races occurring in Israel, Romania, and other European and Asian countries; men generally ran faster than women, particularly in age groups 35-49.

During an IRONMAN, the pacing strategy in the running segment differs significantly between sexes. However, it is unknown if sex affects the running pace in shorter triathlon events. This study compared the pacing strategy between sexes during a 5-km running test performed following a 20-km cycle (sprint triathlon distances).

Background/objectives: Sarcopenia is a muscular disease characterized by loss of muscular strength and function, affecting mainly women, and associated with increased mortality risk. The aim of this study was to compare active women with inactive women of different age groups regarding muscle mass, strength, and muscle quality.

Methods: This study included 147 women (85 runners and 62 inactive), divided into <50 and ≥50 years old.

In this paper, we discuss how artificial intelligence chatbots based on large-scale language models (LLMs) can be used to disseminate information about the benefits of physical exercise for individuals with epilepsy. LLMs have demonstrated the ability to generate increasingly detailed text and allow structured dialogs. These can be useful tools, providing guidance and advice to people with epilepsy on different forms of treatment as well as physical exercise.

Breast cancer is the most common cancer in women worldwide, and its treatment usually involves a combination of many medical procedures, including surgery, chemotherapy, radiotherapy, and hormonal therapy. One of the detrimental effects on physical function is reduced upper limb muscle strength. This study aimed to evaluate upper body strength intra-day and inter-day (test-retest) reliability using the handgrip strength test (HGS) and the bilateral isometric bench press (BIBP) and the test-retest reliability of the one repetition maximum on the bench press (BP-1RM) in breast cancer survivors (BCS).

Purpose: Physical inactivity is considered an important risk factor for osteoporosis, however, some athletes performing extremely high training volumes can also develop bone mass loss. Moreover, the effect of total body mass or body surface area on bone mineral density remains controversial. Therefore, the aim of this study was to compare the absolute bone mineral density and bone mineral density adjusted to body surface area between amateur triathletes and nonactive women.

The present study aimed to compare V̇Omax (absolute, adjusted to total body mass, and adjusted to lean mass) in recreational runners and sedentary women < and > 50 yr and verify the effect of aging and physical activity level on the three types of V̇O max expression. The study included 147 women:85 runners (45.7 ± 14.

Purpose: Endurance sports performance is influenced by several factors, including maximal oxygen uptake (⩒Omax), the percentage of ⩒Omax that can be sustained in endurance events, running economy, and body composition. Traditionally, ⩒Omax can be measured as an absolute value, adjusted for body mass, reflecting the athlete's central capacity (maximal cardiac output), or adjusted for lean mass (LM), reflecting the athlete's peripheral capacity (muscular oxidative capacity). The present study aims to evaluate absolute, total body mass, and lower limb LM-adjusted ⩒Omax, ventilatory thresholds (VT), respiratory compensation points (RCP), and body composition during two training periods separated by 8 months.

Background And Rationale: The literature shows that the prevalence of dietary supplements is high and guidance by a nutritionist or specialized professional is low in professional triathletes. It is reasonable to assume that in recreational triathletes, the prevalence of dietary supplements will also be high and that a significant portion of the sampled population will use supplements without any guidance from a qualified professional. The present study investigated dietary supplement use among Brazilian male recreational triathletes.
