The Effect of Physical Biorhythm Cycle on Some Physical Fitness Factors of Adolescent Volleyball Players

Abstract

Biorhythm is one of the latest topics in the field of identifying mind's ergonomics. Of all the performances with which biorhythm deals is the physical performance. The purpose of present research is to study the effect of physical cycle of biorhythm on the designated factors of physical fitness among teenage volleyball players in the city of Qom. In the present field research, 30 people were selected out of volleyball players aged 12 to 15 at random in the city of Qom. Biorhythm cycles were obtained with the biorhythm software. Vertical jump and medicine ball throwing were used as tests associating with muscular power; pull-up and sit-up were used as tests associating with muscular endurance in two states of charged (the second position) and discharged (the first position) of biorhythm physical cycle. The statistical correlated t test with the significance level of p≤0.05 was used to analyze data. The findings indicated that the tests pertaining to power including Vertical jump and medicine ball throwing were well-correlated with the physical cycle of biorhythm (p=0.042; p=0.019). However, the muscular endurance tests (revised sit-up and pull-up) did not show any significant difference between the two states and were not correlated with the physical cycle of biorhythm (p=0.75; p=0.73). The predictions by physical cycle of biorhythm on the muscular power of athletes are correct, but it was not possible with the muscular endurance of athletes. Of course, more researches should be conducted to increase the certainty of correctness predicted by the physical cycle of biorhythm. The prediction of this theory can be used to increase the performances of athletes in sports competitions if the biorhythm cycles prove right.

Musicians: Larks, Owls or Hummingbirds?

“…Circadian rhythms regulate a number of important functions that are relevant for human beings [12]. For instance, they seem to influence physical fitness, sleeping patterns, emotional reactions and complex cognitive functions such as mental organization, planning, and problem solving [34]. Circadian rhythms are linked to human biology and genetics, but there is a certain flexibility showing that they can be moderated by culture, socialization and learning [5].…”

Personality Oriented System of Strengthening of Students’ Physical, Psychic and Social-Moral Health

“…Researchers believe that knowing about the athletes` positive and negative phase or critical days of physical cycle by the coach or other people, who are in contact with them, can increase productivity, prevent sports injuries, improve performance and other factors influencing physical performance of athletes (Zareian et al, 2014). However, there are very limited and conflicting results about the application of Biorhythm theory in sports.…”

“…From the perspective of Biorhythm theory, humans are being influenced by physical, emotional and intellectual cycles from the day they are born and continuing until death [19,6]. These cycles include 23-day physical cycle, 28-day emotional cycle and 33-day cognitive cycle, each of which has the following features [11,5]: a.…”

Statistical Analysis of the Best Athlete (MPV) in the Men’s Grand Final in the 2023 Proliga Volleyball Competition

“…Each player's roaming range in volleyball is very different; The player with the shortest cruising power is the middle blocker, and the player with the farthest cruising power is the setter. Physical training should consider the somatotype of volleyball athletes when designing individualized exercise programs for each athlete (Zareian et al, 2014). The physical training component must be able to form athletes with power abilities, especially the lower limbs and upper limbs (Milić et al, 2017).…”
