A Comparative Study of White Muscle and Red Muscle Fiber Architectural Parameters

Abstract

The primary objective of this research was to compare red muscle fiber and white muscle fiber muscle architectural parameters of vastus lateralis (VL). The study sample consisted of 70 recreationally active male students from Gwalior, Madhya Pradesh. One repetition maximum Dr. Hatfield test was used to determine muscle fiber type. Thirty (N1 = 15 red muscle fiber group and N2 = 15 red muscle fiber group) out of 70 samples were retained in study for further evaluation. Muscle architectural parameters (VL, pennation angle [PA], fascicle length [FA], and muscle thickness [MT]) were measured using B-mode ultrasonography. Independent sample t-test was employed to determine a significant difference between selected white muscle fibers group and selected red muscle fibers on the basis of selected muscle architectural parameters. The vastus lateralis muscle showed differences in its PA, FA, and MT between different muscle fiber groups. The PA of red muscle fiber group was greater than white muscle fiber group, whereas the FA and MT of white muscle fiber group were greater than red muscle fiber group. In conclusion, architectural parameters studies carried on specific sports group will be helpful in future, and muscle architectural parameters may be considered as a new approach for muscle fiber type classification in the future.

“…Muscle architecture refers to the arrangement of muscle fibers within a muscle and how they contribute to its function. (Kumar, 2023) [8] There are three main components of muscle architecture: fiber length, pennation angle, and muscle thickness. Fiber length refers to the length of the muscle fibers themselves, which can vary greatly between different muscles.…”

“…(Khare et al, 2023) [5] The fiber length, pennation angle, and muscle thickness not only affect the mechanical properties of the muscle but also play a significant role in its overall performance. (Kumar, 2023) [8] For example, muscles with longer fibers have been associated with a greater range of motion, whereas muscles with a higher pennation angle are better suited for generating force. (Kumar, 2022) [12] (Kumar & Jhajharia, 2020) [11] Furthermore, understanding these architectural elements can provide valuable insights into injury prevention, rehabilitation, and exercise programming tailored to an individual's specific needs.…”

Athletes with lesser pennation angle tend to have muscles that are more parallel to the line of pull, allowing for greater excursion and range of motion.…”

“…This variation in muscle architecture impacts an athlete's performance in sports that require different types of movement, such as sprinting, jumping, and weightlifting.

Cricket in this 20 th century became very competitive and has evolved into a psychological (Jadaun et al, 2021) [4] , physically demanding sport that requires a combination of strength, speed, endurance, accuracy (Gautam & Kumar, 2018) [1] , coordination and agility.…”
