Apple Cider Vinegar: Use For Leg Cramps, and More (Updated) Runners, Hydrarion Results-driven weight loss supplements point, are left wondering Hydration and sports-related cramps Hyxration causes these cramps. Do cramps happen Sports Team Training Programs a result of a sports-relared of minerals or dehydration? The question that then arises is if a lack of minerals or water does cause cramps, why do we not get cramps throughout our body? They differ from cramps associated with mineral deficiencies or dehydration. The deficiencies can happen due to a number of factors, such as diarrhea, severe vomiting, pregnancy or the use of diuretic medication.

Hydration and sports-related cramps -

Study design and the time course of measurements taken in the study. Before downhill running DHR , blood sample was taken to assess haematocrit Hct , haemoglobin and serum osmolality, and to measure serum sodium, potassium, magnesium and chloride concentrations, and threshold frequency TF of electrical train stimulation to induce muscle cramp was measured as an indicator of muscle cramp susceptibility.

Immediately after DHR, blood sample was taken for the analyses shown above, and TF was measured again. During DHR, heart rate HR Model Si; Polar Electro Oy, Finland and rating of perceived exertion RPE, 6—20 point Borg Scale were recorded Fig.

Ratings of perceived thermal sensation was assessed with an 8-point thermal rating scale 0: unbearably cold to 8: unbearably hot [ 25 ]. A portion of the blood sample 1. The electrolyte concentrations were measured by an ABBOTT Architect C analyser Abbott Park, IL, USA using a corresponding kit for sodium, chlorine and potassium and using another kit for magnesium Abbott Laboratories Diagnostics, Abbott Park, IL, USA.

Data were assessed by a Shapiro-Wilk test for the normality and a Levene test for the homogeneity of variance assumption. The distance covered in the DHR was 5. The variability among the participants was due to the velocity used in the DHR depending on the fitness level of the participants.

The average HR, RPE and thermal sensation during DHR were The tympanic temperature increased from No particpants experirnced muscle soreness after DHR. The total amount of fluid intake during DHR was The total amount of fluid intake during and after exercise was not significantly different between conditions No significant differences between conditions were found for the baseline values of Hct, Hb and serum osmolality Table 1.

Hct and Hb did not change significantly immediately after DHR for both conditions, but serum osmolarity decreased immediately post-DHR for the spring water condition only. Percent changes in plasma volume were calculated using the equation by [ 28 ].

Plasma volume increased 6. No muscle cramp occured during DHR in both conditions. TF at baseline was not significantly different between the spring water Figure 2 shows absolute changes in TF following DHR from the baseline.

TF decreased by 3. In contrast, TF increased by 6. As shown in Table 1 , no significant differences in serum electrolyte concentrations were evident between conditions at the baseline.

No significant differences were found between conditions for the changes in all electrolytes except chloride, but significant decreases in serum sodium and chloride concentrations were observed only for the spring water condition at immediately post-exercise.

The results of the present study showed that the TF to induce muscle cramp after DHR increased with the ingestion of OS-1 during DHR, but decreased with spring water ingestion during DHR. This supported the hypothesis that post-exercise muscle cramp susceptibility would be decreased by ingestinon of ORS but increased by spring water during exercise.

In comparison to the previous study [ 14 ], in which no fluid intake was allowed during DHR, the increases in HR It appears that the fluid intake during DHR reduced the increase in core temperature, which lowered HR and RPE.

As shown in Table 1 , no significant changes in Hct and Hb from baseline to immediately after DHR were observed for both conditions. Furthermore, plasma volume was greater for the OS-1 than spring water condition from the baseline to immediately post-exercise, suggesting that water absorption was greater for the OS-1 condition.

Serum osmolality and sodium concentration slightly decreased for the spring water condition, suggesting that sodium concentration in the blood was more diluted after the spring water than OS-1 ingestion. This may be due to the relatively shorter duration and lower-intensity of the exercise.

It does not appear that a decrease in serum sodium concentration per se is a cause of muscle cramp. However, it is possible that sodium or other electrylyte concentrations of inside and outside of muscle fibers are changed without changes in their serum concentrations.

It is interesting to use a microdialysis or other technique to investigate changes in intracellular and extracellular electrolytes after spring water versus OS-1 or other ORS. It should be noted that TF measures do not provide cramping intensity and duration, nor the extent of pain associated with the muscle cramp.

However, TF has been used to assess muscle cramp susceptibility in the previous studies for the abductor halluces muscle [ 22 , 23 , 29 ] or the plantar flexors [ 14 , 19 ]. Minetto et al. Behringer et al. In the present study, the baseline TF was consistent Although the present study was not able to assess muscle cramp susceptibility during DHR exercise, the decrease in TF at immediately post-DHR is likely to indicate increased muscle cramp susceptibility during exercise.

This finding was in line with the study by Miller et al. In regards to the relationship between dehydration serum sodium concentration and muscle cramp, Schwellnus et al.

Sulzer et al. In contrast, Hoffman and Stuempfle [ 6 ] showed no difference in serum sodium concentration at the finish of a km ultramarathon among those with muscle cramping, near cramping and no cramping in the last stage of the race. Using TF to assess muscle cramp, Miller et al. Braulick et al.

Additionally, no significant correlations were evident between the magnitude of change in TF and the magnitude of changes in serum sodium or chloride concentration. These suggest that muscle cramp susceptibility is not determined by serum sodium and chloride concentrations alone.

One of the limitations of the present study was that a control condition of no fluid ingestion during exercise was included to compare with other conditions. However, our previous study [ 14 ] showed that TF did not change significantly at immediately after DHR from the baseline without fluid intake during exercise.

Thus, it seems likely that no significant change in TF would have been observed, if no fluid ingestion during exercise condition had been included.

However, the slope of the DHR was not steep, and none of the participants experienced any delayed onset muscle soreness after the first bout. Moreover, the order of the two conditions was counterbalanced among the participants, and it appeared that all participants recovered fully from the previous bout in 1 week.

Thus, it seems likely that the results reflected the fluid conditions rather than the order of the conditions. In the previous study [ 14 ], TF increased after OS-1 intake by 3.

In the present study, TF increased by 6. It is possible that the increases in TF after OS-1 ingestion suggest a decrease in muscle cramp susceptibility. Thus, it might be that the increase in TF was more due to glucose than electrolytes.

Unfortunately, glucose concentration in the blood was not measured in the present study. It is necessary to add the same amount of glucose to spring water to examine the effects of glucose on muscle cramp in a future study. It is possible that sodium in OS-1 stimulated TRP receptors in the gastrointestinal tract.

It would be interesting to investigate how spring water or OS-1 intake affects oropharyngeal reflex, muscle spindles, Golgi tendon organs and alpha motor neurons, and how a small change in electrolyte concentrations in the extracellular fluid surrounding muscle fibres could affect muscle cramp susceptibility.

It is also necessary to include female participants, athletes, and other age groups to confirm the present study findings. The goal of fluid intake during exercise is to prevent excessive dehydration and changes in electrolyte balance [ 32 ].

Evans et al. Thus, to prevent EAMC, ingesting OS-1 appears to be effective, but further research is warranted to investigate how OS-1 works to reduce the muscle cramp susceptibility.

In the present study, no muscle cramp assessment was performed during exercise, and no voluntary muscle cramp was observed. It would be interesting to observe whether muscle cramp does not occur during exercise, when OS-1 or other ORS is ingested during exercise.

It was concluded that spring water intake during exercise in the heat increased muscle cramp susceptibility after exercise downhill running , and ingestion of OS-1 decreased the muscle cramp susceptibility. These were in line with the findings of our previous study [ 14 ] showing that spring water intake after dehydration made muscles more susceptible to muscle cramp, but when OS-1 was consumed, the muscle cramp susceptibility was reduced.

It should be further investigated as to what and how much electrolytes should be contained in the beverage, and whether commercially available sport drinks that contain some electrolytes are as effective as OS-1 in reducing muscle cramp susceptiblilty.

What Are the True Causes of Cramps While Running? Phattarapon Atimetin, M. on May 15, Bones and Joints Sports Medicine Running Sports Injury Rehabilitation Exercise Cramp. Cramps do not result from a body that lacks minerals or hydration.

They occur because of over-contraction or overuse of muscles, or lack of muscle strength. Runners who experience cramp while competing tend to have over-trained in the three days prior to the event. Contrarily, the correct way to prepare is to reduce training load and get plenty of rest before the competition day.

When a cramp does occur, the fastest and most effective way you can relieve it is to stretch the affected muscle. This is because stretching will stimulate the muscle into preventing contractions, meaning the cramp will go away.

Causes of cramps Runners, at some point, are left wondering what really causes these cramps. Altered neuromuscular control The theory explains that contracting or flexing of muscles happens as a result of neurological signals which must maintain a balance. So, what can be done to stop cramps occurring while running?

Pacing Research has found that groups who suffer from cramps are runners who start out too fast in the first half of their race. Tapering Research also found that runners who experience cramp while competing tend to have over-trained in the three days prior to the event. Muscle damage An effective way to measure how much muscle damage has occured is to compare the creatine kinase levels.
